Abstract
A series of novel fused heterocycle methyl esters were designed and synthesized as human nonpancreatic secretory phospholipase A₂ (hnps-PLA₂) competitive inhibitors. Among the 22 synthesized compounds, 17 quinoline-4-methyl esters displayed hnps-PLA₂ inhibition activity in the in vitro bioassay. The IC₅₀ value for the best compound 3o was 1.5 μM. The structure-inhibition-activity relationships of the compounds were studied using molecular docking.
