Abstract

Some new diazo incorporated coumarin compounds were designed and synthesized to evaluate their anti-HIV activity. Overall, compounds were active against HIV at 100 μM. Additionally, no cytotoxic effect was observed at this concentration. The compound with 4-chlorobenzyl group indicated the best anti-HIV activity (52%). Docking studies using the later crystallographic data available for PFV integrase showed similar binding modes to HIV-1 integrase inhibitors. On the basis of these data, nitrogen atoms of 1,3,4-oxadiazole ring have been involved in the Mg2+ chelation and 4-chlorobenzyl group occupies the same position as 4-flourobenzyl group of raltegravir in the active site. In addition, in silico ADME assay demonstrated favorable physicochemical properties for the new designed compounds. Thus, synthesized structures could be introduced as a novel template for designing safe anti-HIV compounds with integrase inhibitory potential.
