Quinoline-4-methyl esters as human nonpancreatic secretory phospholipase A₂ inhibitors

Bioorg Med Chem. 2011 Jun 1;19(11):3361-6. doi: 10.1016/j.bmc.2011.04.039. Epub 2011 Apr 22.

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.
