Abstract: Cytosolic phospholipase A2 is consided as an important fact that will induce arthritis. We have studied the three-dimensional quantitative structure activity relationship for a series of reported pyrrolidine based inhibitors by the comparative molecular field analysis. One representative compound of the series 1a was docked onto cPLA2 (PDBcode: 1CJY) by using Dock and Autodock program to determine the most likely binding conformation to cPLA2. The strategy of all-placement search was used in the CoMFA study to give a final model with the cross-validation q2 of 0.701 and the total analysis of the CoMFA coefficients map gives insights to the design of better cPLA2 inhibitors.

Key words: Comparative molecular field analysis(CoMFA), Cytosolic phospholipaseA2 (cPLA2), Pyrrolidine inhibitor
