Varespladib methyl (A-002; LY333013) is a selective inhibitor of group II secretory phospholipase A2 (PLA2).

IC50 & Target

phospholipase A2 (PLA2)[1]

In Vitro

Varespladib methyl (LY333013) is an orally-administered methyl ester pro-drug that is metabolized to LY315920[1]. Varespladib and its orally bioavailable prodrug, Varespladib methyl (methyl-Varespladib) shows high-level secretory PLA2 (sPLA2) inhibition at nanomolar and picomolar concentrations against 28 medically important snake venoms from six continents[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
