Biological Evaluation and Docking Analysis of Daturaolone as Potential Cyclooxygenase Inhibitor

Abstract

This study deals with the isolation of the active constituent(s) from a methanolic extract ofPistacia integerrimaJ. L. Stewart barks and it was also oriented to evaluate thein vivoandin silicoanti-inflammatory activity. By NMR and crystallography techniques, we have isolated a triterpenoid identified as daturaolone (compound1). This compound showedin vivoa significant and dose dependent (1–30 mg/kg) anti-inflammatory activity on carrageenan-induced mouse paw oedema (ED50= 10.1 mg/kg) and on acetic acid-induced writhing responses in mice (ED50= 13.8 mg/kg). In thein vivoexperiments, the effect of tested compound was also evaluated in presence of the reference drug diclofenac (1–30 mg/kg). Moreover,in silicoanalysis of receptor ligand complex shows that compound1interacts with cyclooxygenases (COXs) binding sites displaying an interesting interaction with COX-1. These findings suggest that compound1isolated fromP.integerrimapossessesin vivoanti-inflammatory and antinociceptive potentials, which are supportedin silicoby an interaction with COXs receptors.
