possesses anti-inflammatory activity. The binding of curcumin with PLA2 was studied using X-ray crystallography. Since the electron density found in the active site did not match with curcumin, (the photo-degraded product of curcumin) in the unexplained electron density. To understand the , molecular docking studies was carried out. with respect to the ligand position and identified that of PLA2 with a binding energy -16.81 Kcal/mol. The binding mode is in such a manner that it can prevent the entry of substrate to the hydrophobic active site. These studies indicate that curcumin can be act as an inhibitor to PLA2.
