Snake bite envenomation is resulting in high rates of mortality and morbidity all over the world. In developing countries like Pakistan, the burden of snake bite is hard to estimate due to the insufficient epidemiological data, as victims receive traditional health care instead of hospitalization.Full Text

The present work is designed to synthesize 2,5-disubstituted-1,3,4-oxadiazole derivatives 5a–5d as snake venom phospholipase A2 (PLA2) inhibitors. The snake venom was isolated from Naja oxiana by pressing their glands below eyes to perform anti-PLA2 activity. The compounds 5a–5d showed good PLA2 inhibitory potential, especially 5d exhibited excellent activity having IC50 value 0.002 mM (0.01 > p > 0.001) followed by 5c having IC50 value 0.003 mM (0.01 > p > 0.001). Compounds 5a and 5b have IC50 values 0.027 mM (p < 0.001) and 0.014 mM (p < 0.001) respectively. The docking results showed that all compounds have binding interactions with amino acid residues in active binding site. They have good binding affinities, particularly 5d has binding energy –6.8 kcal/mol compared to other analogues. On the basis of dry and wet lab results, it may proposed that 5d may act as a potent inhibitor of PLA2 in N. oxiana venom.Keywords
