— Dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS) caused by the DENV virus are among the global problems regarding mosquito-borne viral infections. The DENV virus is transmitted through Aedes aegypti causing clinical manifestations that can cause critical illness for patients. The need for effective antiviral therapy is needed to treat DENV virus infections. 1-Deoxynojirimycin (DNJ), one of the many imino sugars found in mulberry leaves and several strains of bacteria, has potential as an antiviral against DENV virus infection. The antiviral activity of DNJ works as an inhibitor of the α-glucosidase enzyme which is important in virus secretion so that it affects the infection rate. DNJ also has the effect of boosting the immune system to initiate an immune response to a viral infection. Further research is needed to develop DNJ as an effective antiviral DENV in the future.
