Abstract: | We have synthesized a new series of azo‐bis antipyrine derivatives from a one‐pot multicomponent Knoevenagel/Michael addition reaction of antipyrine, with a diversity of azo aldehydes in ethanol and L‐Proline as a catalyst under reflux condition. The anti‐inflammatory activity of the final products was assessed using the inhibition of albumin denaturation technique. Compound 3f showed an inhibitory effect with IC50 values of 3.6 μM with respect to the standard anti‐inflammatory drug Aspirin, with IC50 values of 2 μM. In addition, molecular docking was performed to confirm the in vitro results against the enzymatic inhibition activity of COX‐2 enzymes in which compound 3f showed good binding affinity with an inhibition constant (Ki) of 1.79 nM. |
