Abstract
A new series of functionalized fused pyridines 4(a‐i) and fused pyrido[2,3‐d]pyrimidines 8(a‐c) were designed and synthesized through a multi component reaction where in pyridine ring formation step plays a key role. All the newly formed compounds were well characterized by spectral techniques such as FTIR, 1HNMR, 13CNMR, HRMS and XRD. The potential therapeutic activities such as anti‐inflammatory activity by protein denaturation and RBC membrane stabilization methods, and anti‐oxidant activity by DPPH scavenging method of the newly synthesized compounds were studied. Interestingly, in‐vitro testing of these compounds reveals that the compounds 4d, 4g, 4i, 8a and 8b showed comparable anti‐inflammatory activity with respect to the standard drug, diclofenac. Similarly, fused pyridine 4f showed excellent anti‐oxidant activity when compared with the standard, ascorbic acid.Keywords
