Description: Varespladib, aslo known as LY315920, is a secreted phospholipase A2 (sPLA2) inhibitor (IC50 = 50 - 750 nM for a range of sPLA2 isoforms). Varespladib reduces atherosclerosis and aneurysm formation in ApoE-/- mice and in guinea pigs. Varespladib significantly reduces the post-ACS inflammatory response in those with and without diabetes. Varespladib may be potentially useful for treatment of coronary artery disease.
