Cancer is one of the significant causes of mortality worldwide. Studies on antineoplastic drugs focused on natural products have revealed several mechanisms to inhibit cancer cells. Bugnay (Antidesma bunius) leaves showed potentials due to its activity observed against brine shrimp and breast cancer cells. However, there is still limited knowledge about its activity against other human cancer cells. This study focused on determining the phytochemical compounds in A. bunius leaves extract, the free radical scavenging activity of the extract using the Diphenylpicrylhydrazyl (DPPH) method, and in vitro cytotoxic activity against two cancer cell lines, namely HCT-116 human colorectal and A549 human lung adenocarcinoma cancer cell lines by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The phytochemicals identified were unsaturated lactones, flavonoids, phenolics, diterpenes, saponins, tannins, carbohydrates, and reducing sugars. The extract showed significant free radical scavenging activity and a direct correlation of activity with concentration levels. It also exhibited cytotoxic activity against HCT-116 human colorectal and A549 human lung adenocarcinoma. Hence, A. bunius leaves have the potential to be a source of antioxidant and antineoplastic compounds. This warrant further isolation of the compounds for chemotherapeutic purposes.Keywords: Antidesma bunius, Bugnay, Cancer, Cytotoxicity, Radical

Breast cancer remains as one of the highest causes of cancer-related deaths in the world, including Indonesia. In spite of following the standard protocol therapy, some patients in developing countries consume medicinal herbs as an alternative, complementary, as well as supportive therapies. Several herbs have been recognized to be used for this purpose. Annona muricata, Curcuma longa, Curcuma zanthorrhiza, Curcuma zedoaria, Phyllanthus urinaria, Gynura procumbens, Garcinia mangostana, Morinda citrifolia, and Nigella sativa are some of the plants used as chemopreventive agents with several formulas. Various types of extracts of Annona muricata show anticancer activities in vitro and in vivo. Curcumin, obtained from Curcuma longa and Curcuma zanthorrhiza, acts as p53 regulator and pro-oxidant in MCF-7 cells and also acts as a fatty acid synthase inhibitor in MDA-MB-231 cells. Xanthorrhizol from Curcuma zanthorrhiza has pro-apoptotic activity via modulation of Bcl-2, p53, and PARP-1 protein levels. Curcuma zedoaria contains curcumenone, curcumenol and curdion, which show pro-apoptotic activity in various cell lines and a cancer-induced mouse model. Corilagin and geraniin from Phyllanthus urinaria have different pro-apoptotic effects, in which, the corilagin-caused apoptotic effect is mediated by extrinsic and mitochondrial pathways, whereas geraniin induces apoptosis via ROS-mediated stimulation, both in MCF-7 cells. Thymoquinone from Nigella sativa has been extensively studied for its anticancer activities in recent years. Plants are cultivated, collected and mixed depending on the use as herbal medicines. Active compounds might be formulated if deemed possible. The development of more potential derivatives is also necessary to produce more optimum anti-cancer agents. In conclusion, Indonesian plants and their active constituents show potential activities to be developed as chemopreventive agents.Keywords: Indonesian medicinal herbs, breast cancer, active constituents, molecular targets

Breast cancer (BC) and cervical cancer (CC) have a high prevalence and mortality rate worldwide. Despite the availability of advanced treatment, resistance to conventional chemotherapies has emerged. Myrmecodia pendens, one of the species of Sarang Semut (local name), possess a potential of antitumor effects by inducing cell death different cancer cell entities. This study aimed to assess anti-tumor activities of n-hexane fraction of M. pendens in inhibiting cell survival and cell migration in BC and CC cells. M. pendens was extracted in methanol then fractionated using n-hexane or ethyl acetate. BC cells including MCF-7 (luminal A), HCC-1954 (HER2+) cells and CC Hela cells were treated with M. pendens extracts to evaluate cytotoxic activity using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay as well as anti-cell migration using scratch assay. We also analyzed inhibitory concentration 50 (IC50) of n-hexane fraction in BC and CC cells. We started with comparing cytotoxicity activities of methanol extract, ethyl acetate and n-hexane fractions of M. pendens. Data showed that the n-hexane fraction was the most potent inducing BC cell death. Therefore, we used the n-hexane fraction for further experiments. Interestingly, IC50 of this fraction in HCC-1954 and Hela cells were lower than in MCF-7 cells, 16; 13 and 60 ppm, respectively. Moreover, the low concentrations of n-hexane fraction inhibited HeLa cells migration, compared to control group (p

Concerns are growing about human exposure to endocrine-disrupting chemicals (EDCs), especially during the preadolescent development stage. Parabens are prevalent EDCs widely used as additives in cosmetics. So, the determination of parabens in such products is important. In this study, we developed a reliable and sensitive method to determine simultaneously nine common parabens (methylparaben, ethylparaben, phenylparaben, benzylparaben, penthylparaben, and two groups of isomeric compounds include propylparaben, isopropyl paraben, and butylparaben, isobutylparaben) in cosmetics products. The QuEChERS and solid-phase extraction techniques are used for extraction parabens from non-surfactant cosmetics (perfume, mouth wash solution) and surfactant cosmetics (shampoo, cream, gel), respectively and quantified by using ultra-performance liquid chromatography coupled with the ultraviolet-visible detector. All nine compounds showed good linearity with regression coefficients predominantly above 0.990. The LOD and LOQ of parabens were 0.07 µg/mL; 0.2 µg/mL, respectively. The recoveries ranged from 80 to 110% with the relative standard deviations below 8%. The developed method was successfully applied to determine parabens in various commercial cosmetic products from a local supermarket and the total parabens concentrations are in a wide-ranged from 2.0 to 1270 mg/kg.

The use of deltamethrin and cypermethrin insecticides to control pests has been implemented in Indonesia. Irregular and excessive use of insecticides can have toxic effects on the male reproduction system. Deltamethrin and cypermethrin insecticides can inhibit androgen biosynthesis and disrupt the growth of sperm. Therefore, this research is conducted to find out the effect of deltamethrin and cypermethrin insecticides toward the level of intratesticular testosterone in male Wistar strain rats. This research is conducted in vivo using male Wistar strain rats. Nine rats are divided into three groups of treatment, namely control group, deltamethrin group with 0.26 mg/kg of weight, and cypermethrin group with 0.26 mg/kg of weight. Treatment is conducted every day for 15 days orally, and then the rats are dissected to take their testicles. Testicles are chopped and their intratesticular homogenates are taken by adding the medium of DMEM and collagenase (0.25 mg/mL). The measurement of the level of testosterone is conducted by using Electrochemiluminescence immunoassay (ECLIA) method. Data on the change of the increase of body weight, organ weight, and the level of testosterone is analyzed statistically using the one-way ANOVA test. The research result shows that giving 0.26 mg/kg of weight of deltamethrin and 0.26 mg/kg of weight of cypermethrin does not affect the increase in body weight, relative weight of the reproductive organ, and the level of intratesticular testosterone of male Wistar strain rats.

Cervical cancer is one of the most leading causes of women death. Currently, paclitaxel is still one of the main therapeutic regimens for cervical cancer patients. However, some patients developed to be paclitaxel-resistant. Hence, studies to find out the novel strategies to resolve this problem are important. Generating resistant cancer cell lines can be utilized as the potent tool to evaluate the efficacy of any therapeutic agent toward cancer drug-resistant problems. Current studies describing the methods to establish chemoresistance are lacking. Moreover, study in Indonesia conducting chemoresistance in cell line is limited. This study was aimed to elaborate the characteristics of HeLa cells during generation of paclitaxel-resistant cervical cancer cells. The parental HeLa cells were exposed to an escalating concentration of paclitaxel for a long time period. Subsequently, cells were divided into two groups for the evaluation of resistance characteristics. The values of inhibitory concentration 50 (IC50) and inhibitory concentration 90 (IC90) were analyzed using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay. Our data showed that the longer exposing periods of paclitaxel, the higher IC50 and IC90 values of HeLa cells are. IC90 of paclitaxel in HeLa Pac RB was increased from 69 pM, 440 pM, 2,561 pM and 10,337 pM on 0th, 1st, 2nd, 3rd and 4th months, respectively. Interestingly, the resistant cells were recovered to be paclitaxel-sensitive when they were not being continuously exposed to paclitaxel. In addition, the paclitaxel resistant cells become less sensitive against 5-FU but not doxorubicin, cisplatin and etoposide. We were able to generate cervical cancer HeLa paclitaxel-resistant cell line. These cell line could potentially be utilized for further studies in order to understand the molecular mechanisms of drug resistance in cervical cancer and as a tool for cancer drug discovery.Keywords: cervical cancer, drug resistant cell line, paclitaxel resistant cells, stepwise escalating concentration.

However, reports on the mode of action and detail mechanism of curcumin in breast cancer disease are limited. Hence, curcumin’s effect on the human breast cancer cell line MCF-7 and MDA-MB-468 was investigated. The MCF-7 and MDA-MB-468 breast cancer cells line were given curcumin in several doses. The anti-proliferation activity of curcumin was determined using the MTS cell viability test and caspase-3 activity was used to detect apoptosis using flowcytometry. The expression of Ras-association domain family 1 isoform A (RASSF1A) and Bax protein in cells was evaluated by ELISA analysis. Kruskal-Wallis followed by the Mann-Whitney test and the Spearman correlation tests were used to asses correlation among RASSF1A, Bax, and caspase-3. Cytotoxicity of curcumin on MCF-7 was lower than that of MDA-MB-468 (75.73 μg/mL and 380.79 μg/mL). The concentration of curcumin at 80 μg/mL induced apoptosis mainly through the intrinsic pathway by caspase-3 activation. Curcumin also showed an anti-proliferative activity as shown by the increase of RASSF1A and Bax protein. Curcumin mediates anti-proliferative and apoptotic effect through the activation of RASSF1A and Bax. Our research data adds information about the role of curcumin in epigenetic events through RASSF1A protein.Keywords: Bax, caspase-3, curcumin, MCF-7, MDA-MB-468, RASSF1A

Quantitative analysis of bioactive peptide mostly conducted by measuring the activity. While the determination of peptide content in natural sources has been conducted using various instruments, vibrational spectroscopy remains underutilized. Here, we attempted new developed method in peptide quantification and degradation kinetic analysis using Fourier-Transform Infrared Spectroscopy. Bovine Serum Albumin was used as standard protein in method development and validation. Peptide content was estimated by converting peak area to concentration. The method was used to estimate peptide content in Canarium nut protein and its hydrolysates, which potentially hold biological activity. Kinetic study was conducted with microwave as an accelerator for hydrolysis, an apparatus rarely used in peptide study. Amide I band on wavenumber range of 1724.05-1619.91 cm-1 was selected for analysis, considering its selectivity and linearity. The method also met other validation requirement, including accuracy and precision. When applied in quantitative analysis, the method was able to calculate peptide content decrease in Canarium nut protein after hydrolysis using papain (38.24%), pepsin (33.67%) and alkaline reagent (28.53%). In kinetic study, microwave-assisted peptide degradation exhibited logarithmic profile with the equation of y=-0.148ln(x)+0.9591 and R² value of 0.963. Based on these results, FTIR is useful in estimating peptide content and in analyzing degradation kinetic profile.

Ethanolic extract and brazilein-containing fraction of Caesalpinia sappan L., has been reported to inhibit cell proliferation in T47D (ER+ PR+/- cell, Luminal A subtype model). The Luminal A subtype is the most common subtype of breast cancer in Indonesian women. In this study, we explored the activity of the reduced form of brazilein, i.e. brazilin, in T47D cells proliferation and the mechanism that involved. The cytotoxicity activity of brazilin was observed using MTT assay. While the cell cycle modulation analysis was done by using flowcytometry, and the senescence assay was observed using S-A-β-galactosidase assay. The results showed that brazilin inhibited cell growth in a dose-dependent manner with an IC50 value of 50μM (or 14.3μg/mL). That was higher than a brazilein-containing fraction, which was reported previously by our group to have an IC50 value of 68μg/mL against the same cell. Cell cycle analysis showed that cells treated with brazilin were accumulated at the G2/M phase in a dose-dependent manner. Furthermore, cells treated with a combination of brazilin and doxorubicin was accumulated at the G2/M phase and sub G1 phase. Cells accumulation at sub G1 phase indicates that the cells undergo apoptosis. Our data of S-A-β-galactosidase assay showed that cells treated with 1/4IC50, 1/2IC50, and IC50 brazilin had lower senescent cells compared to the untreated cells. The morphology of cells treated with IC50 (50μM) brazilin changed. The cells shape became rounded, cells were shrinkage and detached from the well plate, indicating that cells may undergo apoptosis. These results suggested that brazilin was cytotoxic towards T47D cells and its combination with dox potentially induced apoptosis and decreased cell senescence. The ability of brazilin to decrease cell senescence provides new insight of utilization of C. sappan or its constituents, particularly brazilin, as anti-ageing.

Our previous study showed that kaffir lime leaf extracts may have anti-cancer properties. However, production of bioactive compounds is affected by environmental factors. Here, we present a method to control environmental conditions using in vitro culture techniques such as callus induction. Calluses were induced from seed embryo explants of kaffir lime on MS medium with combinations of 2,4-D and BAP at concentrations 1:0.5; 1:1; and 2:1, respectively. Fourty and 60 days-old calluses were extracted using chloroform and ethyl acetate and analyzed by GC-MS. Results showed all combinations of 2,4-D and BAP were able to induce callogenesis from seed embryo explants of kaffir lime with no significant differences of callus initiation time, biomass, morphology and growth rates. However differences were detected in the bioactive compound profiles. In kaffir lime callus, both fatty acids and secondary metabolites were detected. Specifically, in 40 days-old calluses (exponential growth phase) we detected α-pinene and 1.8–cineole in plants treated with 2,4-D: BAP at concentration 1:0.5 and 2:1. In 60 days-old calluses (stationary phase) we detected a number of compounds in plants treated with 2,4-D:BAP at concentrations of 1:0.5 and 2:1, including caryophyllene, linoleoyl chloride, thiogeraniol, stigmasterol, clianosterol, citronellal, neo-isopulegol, citronellol, geraniol, eugenol, cyclopropane, pristane, elemol and farnesol

Harmsiopanax aculeatus leaves, a medicinal plant with locally named kapur, have been used traditionally to treat malaria in Maluku, Indonesia. However, the scientific information of this plant is still limited. In our previous study, the methanol extract of this plant leaves have been proven to possess in vitro antiplasmodial activity. This study was conducted to evaluate in vitro antiplasmodial activity and cytotoxicity of subfractions of the plant leaves. Fractionation was performed using a column chromatography with Sephadex LH-20 as the stationary phase and methanol as the mobile phase. The subfractions obtained were then tested for in vitro antiplasmodial activity on a chloroquine-resistant FCR3 strain of Plasmodium falciparum using a visual method. Cytotoxicity was evaluated by using MTT assay. The in vitro antiplasmodial activity and cytotoxicity were expressed as IC50, calculated using probit analysis with SPSS 16 for windows. The results showed that the four subfractions tested have a high antiplasmodial activity with IC50 values of 0.09; 0.18; 0.01; and 0.77 µg.mL-1, respectively. In addition, these subfractions had IC50 values of >400 µg.mL-1 against Vero cells indicating that they were non-toxic. In conclusion, the subfractions of H. aculeatus leaves are very active and selective against P. falciparum. Further study will be conducted to isolate the active compounds.

Over-the-counter (OTC) cough and cold medications (CCMs) have been used to treat the symptoms of upper respiratory infection in children for decades. The safety of CCMs in children has been questioned. The data on knowledge of pharmacists in supplying cough medicines for children under two years have been limited. This study aimed to evaluate the pharmacists’ dispensing decisions to manage the cough in children under two years old. A descriptive cross-sectional was carried out in 300 pharmacies in 15 districts in Ho Chi Minh City, Vietnam. The pharmacists were interviewed by a simulated patient. The results showed that, information that pharmacists actively asked the client about the patient and disease symptoms was limited. Most pharmacists did not provide adequate instructions and counsel about using drugs for clients. Only 22/300 (7.33%) of pharmacists appropriately provided cough medicines for children under 2 years old. The main reason of inappropriateness was the deficiency of knowledge about updated contraindication of N-acetylcysteine (93.17%). Pharmacists in pharmacies located in districts 3, 11 and Binh Thanh had higher rate of rational provision than those in other districts. A good and full understanding of the patient symptom helped the pharmacists supply cough medicines more reasonably. The limited caution of pharmacists and the low proportion of pharmacists updating contraindication of N-acetylcysteine should be considered as a warning sign in pharmacy practice in Ho Chi Minh City, Vietnam.

Okra (Abelmoschus esculentus (L) Moench) fruit is empirically used in type 2 diabetes mellitus treatment. This research aims to know the antihyperglycemic activity of okra fruit extract and fractions in streptozotocin-nicotinamide (STZ-NA) induced as well as in insulin resistance diabetic rats, the effect on pancreatic cells regeneration, and the effect on immunohistochemical expression of glucose transporter-4. This study used a group of 35 male Wistar rats for STZ-NA induced diabetic model and another group of 35 rats for insulin resistance diabetic model. Gliclazide (0.72mg/kg BW) and metformin (45mg/kg BW) were used as drug control in STZ-NA induced and insulin resistance diabetes, respectively. Okra fruit ethanol extract, n-hexane, ethyl acetate, and water fraction were orally administered with dose of 200; 107; 6 and 86mg/kg BW, respectively, for 28 days after diabetic condition was obtained. Blood glucose level was measured every week. Hematoxylin-eosin staining was used to evaluate the pancreatic cells regeneration, while immunohistochemistry was used to evaluate the expression of glucose transporter-4 in muscle membrane cells, at the end of the treatment. The results revealed that ethyl acetate fraction was the most effective in lowering blood glucose level in both condition of diabetes. Ethyl acetate fraction decreased the necrosis of pancreatic cells in STZ-NA induced diabetic rats and increased the expression of glucose transporter-4 in muscle cell of insulin resistance diabetic rats.

Cervical cancer can be treated conventionally with chemotherapy agents, but its use has side effects and complications in the form of damage to normal cells. This study aims to determine the potential of A. platensis as an alternative anticancer agent that is selective towards normal cells. Based on TLC analysis, A. platensis contains antioxidant compounds such as β-carotene, flavonoids, and terpenoids which are able to inhibit proliferation and trigger apoptosis of cancer cells. The study was conducted using cervical cancer cells HeLa and normal cells HDFa. A. platensis macerated with 96% ethanol at a ratio of 1:4. Based on probit analysis, it is known that ethanol extract of A. platensis has a cytotoxic effect on HeLa cells with IC50 values of 260.444μg/mL and index selectivity towards HDFa cells of 7.931. The mechanism of cytotoxic activity of ethanol extract of A. platensis is related to its ability to extend the doubling time, increase the induction of apoptosis, and reduce the rate of cells migration. Ethanol extract of A. platensis can also increase cells accumulation in the S phase to prevent cells from entering the G2/M phase.

Chemotherapy is the first-line treatment for triple-negative breast cancer (TNBC), yet toxicity and resistance effects have been the current problems. Curcumin,a natural compound, has been reported to exert anti-proliferative effects on various cancer cells, including breast carcinoma cells. However, the β-diketone moiety influences the stability of curcumin. Curcumin analogs, pentagamavunon-0 (PGV-0), and pentagamavunon-1 (PGV-1) were synthesized to improve the stability and activity of curcumin by modified the β-diketone moiety into mono-ketone pentanone. In this study, we evaluated the cytotoxicity, inhibition of cell cycle progression, and induction of apoptosis of curcumin and its analogs (PGV-0 and PGV-1) in murine triple-negative breast cancer 4T1 cell line. The cytotoxic evaluation was done by MTT assay, while apoptosis induction and cell cycle evaluation was performed by annexin V staining and detected by flow cytometry. Curcumin and its analogs, PGV-0, and PGV-1, significantly inhibit the viability of 4T1 breast cancer cells with an IC50 value of 34.34µg/mL, 13.76µg/mL and 38.21μg/mL, respectively. Apoptosis analysis with a dose of 10µg/mL and 15µg/mL in 4T1 breast cancer cells showed that curcumin and its analogs effectively induce apoptotic in a dose-dependent manner. In cell cycle analysis using a dose of 15µg/mL, curcumin inhibited the cell cycle progression in the S phase, whereas PGV-0 and PGV-1 inhibited the cell cycle in the G2/M phase. It could be concluded that curcumin analogs, PGV-0 and PGV-1, have higher potential to be developed as anti-cancer agents by inducing cell cycle arrest and apoptosis in triple-negative breast cancer.

Fetal bovine serum (FBS) is a gold standard as a supplement to cell and tissue culture media. This is due to a large number of Growth Factor (GF) contained in FBS. However, the use of FBS is at risk of transferring endotoxins, prions, bacteria and viruses from animals to humans, so it is risky to be used on cell therapy. Human Platelet Lysate (HPL) is a medium that can be developed as an alternative cell growth medium. The advantage of HPL is that it does not contain aggregate platelets so it does not cause the cells to clot. This condition causes HPL to be used as a substitute medium replacing FBS for cell propagation. The use of HPL for cell propagation has been widely reported. However, the use of HPL in cancer cells has not been found. Thus, this study aims to see the effectiveness of HPL as a T47D cell culture medium. The study began with donor selection with criteria for the male sex, the blood type O, the age ≤35 years. Furthermore, the Platelet Concentrate (PC) was processed into HPL then measured pH, total protein and albumin levels. The cell viability was measured using the MTT assay to determine the ability of cell proliferation when propagation using HPL. The doubling time test was carried out as in the cell proliferation test. However, the incubation was carried out for 24 h, 48 h and 72 h and the HPL concentration used was 5%. The result shows that HPL 10% and 20% ability to increase proliferation better than the FBS 10%. HPL with a 5% concentration ability to shortens the doubling time than FBS 10% (doubling time is less than 19.94 h). It this study, cell proliferation is influenced by the pH of HPL and total protein but not by the amount albumin.Keywords: Human Platelet Lysate, Proliferation, T47D cell line, total protein, albumin.

One of the main modalities of cancer treatment is chemotherapy, which uses chemicals that are generally electrophilic. These xenobiotic compounds sometimes does not produce effective response due to activity of glutathione S-transferase (GST) which inactivate the xenobiotics. Several natural phenolic compounds were reported to inhibit GST activity in vitro. Noni fruit (Morinda citrifolia L.) which contains flavonoids and other phenolic compounds such as scopoletin and morindon is proposed to interfere GST activity. This study aimed to analyze the effect of ethanolic extract of Noni fruit in vivo on GST activity in lung rat using 1,2-dichloro-4-nitrobenzene (DCNB). This substrate is a specific for class mu GST. First, rats were administered with ethanolic extract of Noni and dimethylbenz(α)anthracene (DMBA) for two weeks. The cytosolic fraction of lung was isolated then the GST activity was determined by simple kinetic program which was automatically calculated using spectrophotometer. The results showed that ethanolic extract of Noni in 1 and 5% (w/v) of concentration induced class mu GST activity, whereas 10% (w/v) of concentration inhibited class mu GST activity. After a treatment with DMBA, all tested concentrations of ethanolic extract of Noni inhibited class mu GST activity of lung rat significantly. These results indicated that Noni fruit extract can be further developed as a supportive agent of a chemotherapy drug.Keywords: DMBA, GST, Morinda citrifolia L., spectrophotometer.

TNBC, one of the sub type of breast cancers was widely known with high tumorigenic and poor prognosis than others. The development of combination agent (co-chemotherapy) with doxorubicin for chemotherapy of TNBC were carried out to decrease doxorubicin side effect and resistance in cancer. This present study aims to explore the co-chemotherapeutic properties of PGV-0 and investigate induction of doxorubicin on apoptosis, senescence and ROS against TNBC. 4T1 Cell line were used as a TNBC in vitro model. Cytotoxic measurement was performed using MTT assay resulting in IC50 values of 52 μM. Meanwhile, the combination of doxorubicin and PGV-0 showed synergistic effect which decreased cell viability of 4T1 better than single treatment of doxorubicin. Apoptosis analysis was performed using annexin V/PI assay indicated that the combination treatment of PGV-0 and doxorubicin increased apoptosis evidence. Senescence detection was carried out using senescence-associated-β galactosidase (SA-β-gal) assay. The results showed that a single treatment of PGV-0 induced cellular senescence and increased senescence cells in combination treatment. Moreover, DCFDA staining showed that PGV-0 increased ROS level at single treatment, whereas combination treatment increased ROS intracellular compared to the positive control of doxorubicin. Based on these results, PGV-0 has potential as a co-chemotherapeutic candidate on TNBC.Keyword: 4T1, PGV-0, Co-chemotherapy, Cytotoxic, Senescence, Apoptosis, ROS

The utilization of natural resources, one of which is plants, has been researched as an alternative to synthetic drugs because of their natural content. Potato (Solanum tuberosum L.) peels, the parts of potatoes that are often cut off and discarded, have been reported to have some phenolic compounds and flavonoids in their composition. The extract of potato peels was investigated for its analgesic, anti-inflammatory, and anti-biofilm-forming properties. A hot plate test was conducted to assess the analgesic activity in treatment doses of 50 mg/kg, 100 mg/kg, and 200 mg/kg with paracetamol as the reference drug and distilled water as the negative control, while carrageenan-induced paw edema was used to assess anti-inflammatory activity in treatment doses of 100 mg/kg, 200 mg/kg, and 400 mg/kg with diclofenac as the reference drug and distilled water as the negative control. Anti-biofilm-forming activity was tested by using the crystal violet assay. The results showed that, compared with the negative control, treatment doses of 100 mg/kg and 200 mg/kg significantly (p < 0.05) reduced pain stimuli, whereas a treatment dose of 100 mg/kg, 200 mg/kg, and 400 mg/kg significantly (p < 0.05) reduced the edema volume increment. However, compared with the positive control, paracetamol and diclofenac were associated with the least pain stimulus and the least edema volume increment, respectively. Potato peel extract against S. mutans biofilm formation demonstrated effectiveness (p < 0.05). Based on these data, it can be concluded that potato peel extract has analgesic, anti-inflammatory, and anti-biofilm-forming activities, as demonstrated in this study.

Antioxidants are agents that can reduce free radicals. Parijoto fruit (Medinilla speciosa) contains flavonoids that could act as an antioxidant. However, those flavonoids are water-soluble and show low bioavailability. Nanotechnology is a potential approach to improve the bioavailability of flavonoids from Parijoto fruit. This study was conducted to determine the antioxidant activity of parijoto nanoparticles with variations of the chitosan, alginate, and chitosan/alginate encapsulants. Secondary metabolites of parijoto fruit were using the maceration method. The synthesis of parijoto nanoparticles was conducted using the ionic gelation method with chitosan, alginate, and chitosan/alginate encapsulation. Parijoto nanoparticle size and distribution were characterized using Particle Size Analyzer (PSA). The formation of nanoparticles in colloids was determined as a percent. The antioxidant activity of nanoparticle was evaluated using Ferric Reducing Antioxidant Power (FRAP) method using a UV-Vis spectrophotometer. Chitosan encapsulation produced nanoparticles with a size of 269.3 nm, pdI 0.372 and transmittance 99.379%.

The extract of Citrus reticulata has been studied for its biological activities, due to its citrus flavonoid content. The extract and its flavonoid compounds exhibit growth inhibition properties in several cancer cell lines and in vivo models. Conversely, the extract can also induce cell proliferation and angiogenesis, and shows estrogenic effects, in vitro and in vivo. Because of the contrasting effects that depend on the concentration or dosage, the precise action of the extract and its flavonoids need to be elucidated in various cell types. The objective of this study is to evaluate the effect of Citrus reticulata peel extract (Citrus extract) and hesperidin, a citrus flavonoid, on the modulation of cell proliferation in the RAW 264.7 macrophage cell line. Cell viability under Citrus extract or hesperidin treatment was assessed by using the MTT assay. The expression of interleukin-10 (IL-10), an anti-inflammatory cytokine, modulated by Citrus extract was also examined by immunostaining. Low concentrations of Citrus extract at 1 and 100 μg/mL were able to induce cell proliferation, though not significantly, as shown by cell viability of 138 and 114%, respectively. At higher concentrations of 500, 750, and 1000 μg/mL, Citrus extract decreased cell viability significantly by up to 64, 46, and 36%, respectively. Accordingly, hesperidin at low (3.1 μg/mL−61.1 μg/mL) or high (152.6 μg/mL−305.3 μg/mL) concentrations increased or reduced cell viability significantly by up to 116−136% or 10−61%, respectively. The value of the 50% inhibitory concentration (IC50) of Citrus extract was more than three times higher (756 μg/mL) than that of hesperidin (203 μg/mL = 332 μM). Additionally, 250 μg/mL of Citrus extract was able to induce IL-10 expression compared with the control. These results demonstrate that Citrus extract and hesperidin exert a biphasic effect on macrophage cells. The future development of Citrus extract as a co-chemotherapeutic, anticancer, or immunomodulatory agent should include careful consideration of its biphasic effect on each cell type.

L-Citrulline shows potential activity as a supplement to prevent myocardial infarction through vasodilative and possible antioxidative effects but may be deleterious by causing nitrosative stress. This study determined the potentially deleterious effects of L-citrulline supplementation in isoproterenol-induced myocardial infarction with a focus on nitrosative stress. L-Citrulline supplementation was given orally at dosages of 300 or 600mg/kg body weight daily for 6 days. Myocardial infarction was induced in Wistar rats via subcutaneous injection of isoproterenol (85 mg/kg body weight (BW)) on day 4 and 5. Blood pressure was measured at the end of the study (day 6) and rats were sacrificed to collect heart tissue samples for a histopathological evaluation. The histopathological evaluation was done using hematoxylin and eosin staining for the myocardial damage evaluation and immunohistochemical (IHC) staining of arginase-2, inducible nitric oxide synthase (iNOS), and 3-nitrotyrosine to evaluate nitrosative stress. L-Citrulline supplementation failed to show a significant protective effect on blood pressure and exacerbated the decrease of diastolic blood pressure. Both low and high dose L-citrulline supplementation had a significant protective effect on myocardial damage compared to the isoproterenol group (p

A new simple and effective routine analytical method for quantification of curcuminoids in Curcuma xanthorrhiza was developed by high-performance liquid chromatography. This method based on chromatographic fingerprint combined with a quantitative analysis of multi-components by single marker (QAMS). Curcumin was selected as an internal marker for the determination of two other similar compounds, i.e. bisdemethoxycurcumin and demethoxycurcumin, by using the relative coefficient factor (RCF). Excellent linearity was obtained for each component (r2 > 0.9998), and the recovery of extraction methods were within 100.23-103.95%. The precision of the method was good at inter-day and intra-day analysis (RSD < 4.0%). The stability of RCFs was good under various chromatographic conditions with RSD < 1%, and the ratio of retention time was used to locate each compound. The quantification of curcuminoids between QAMS and external standard method (ESM) proved the consistency and similarity of the two method (RSD < 2%). This study demonstrated that QAMS could be used as a routine method for quality control of curcuminoids in C. xanthorrhiza. This method successfully proved accurate, stable, more effective and simple than external standard method.

Senescence defined as an irreversible cell cycle arrest. Senescence can inhibit cancer growth and suppress the progression of cancer. Some anticancer compounds are known to have the potential to induce senescence. Senescence defence against tumor development by preventing proliferation of cells with DNA damage. The study aimed to determine the cytotoxic effects and senescence induction of Pentagamavunon-0 (PGV-0) on Human Epidermal Growth Factor Receptor 2-positive (HER2-positive) breast cancer cells, HCC 1954. Cytotoxic tests carried out with 3- (4.5-dimethylthiazzol-2yl) -2.5-tidiphenyltetrazolium (MTT) assay showed that PGV-0 exhibited a strong cytotoxic effect with a the half maximal inhibitory concentration (IC50) value of 39 μM. Treatment with IC50 in sub-doses combined with doxorubicin showed cytotoxic enhancement effects. The senescence assay using SA-β-Galactosidase showed that the PGV-0 in a single treatment was able to induce senescence with a percentage of cell senescent of 15%. The combination treatment of PGV-0 at the half dose of IC50 with doxorubicin 100 nM was able to induce senescence with the percentage of senescent cells of 25%. Moreover, PGV-0 also increased intracellular reactive oxygen species (ROS). The results of this study indicate that PGV-0 exhibits cytotoxic effect, increases cytotoxic effect of doxorubicin and induces senescence that may correlate to the increasing of intracellular ROS in 1954 HCC cells.Keywords: Pentagamavunon (PGV-0), HCC 1954, Cytotoxic, Senescence

Objective: To investigate the effect of Phyllanthus niruri Linn (Euphorbiaceae) in the proliferation of human leukemic cells (MOLT-4 and K562).Methods: Phyllanthus niruri L (P.niruri) was macerated by using various solvents to obtain the crude extracts. Cytotoxicity of the extracts against MOLT-4 and K562 cells was tested using MTT assay to find the IC50 value. To analyse cell cycle progression, cellular DNA was measured using propidium iodide (PI) staining. Apoptosis induction was evaluated using Annexin V-FITC and PI staining and analysed using FACSVerse flow cytometry. Finally, the expression of p53 on MOLT-4 and K562 cell lysate was measured by western blotting, to identify the possible mode of action of the anticancer activity.Results: P. niruri crude extracts demonstrated a potential anti-cancer effect towards MOLT-4 cells (IC50 range was 42.21 ± 4.98 to 97.06 ± 18.29 µg/ml). However, against K562 cells, P.niruri extracts exhibited a lower inhibitory potency (the IC50 was 120.19 ± 8.48 to 256.55 ± 26.22 µg/ml). The results showed the selectivity of the toxic effect of the extracts against MOLT-4 and K562. To evaluate the possible mechanism of action the anticancer effect, we evaluated P. niruri extract action in apoptosis induction and p53 expression. The results showed that methanol and hexane extract inhibited MOLT-4 cell progression from G1 to S-phase, indicating G1 cell arrest. Moreover, apoptotic cell population following treatment of MOLT-4 and K562 cells with methanol extract was markedly increased, showing morphological signs of apoptosis including membrane degradation and chromatin condensation. Furthermore, we found that there was an increase in p53 expression following MOLT-4 treatment with methanol extract, suggesting that p53 induction may be involved in cell apoptosis.Conclusions: The results indicated the involvement of p53 pathway in the mechanism of anti-cancer activity exerted by P. niruri extract on MOLT-4 cells. However, for cancer cells lacking P53 expression, such as K562 cells, apoptosis might take place via other pathways.
