Anti-Inflammatory, Analgesic Evaluation and Molecular Docking Studies of N-Phenyl Anthranilic Acid-Based 1,3,4-Oxadiazole Analogues

Abstract EN

A novel series of N-phenyl anthranilic acid-based 1,3,4-oxadiazoles were prepared (4a–h) and subjected to anti-inflammatory, analgesic activity and molecular docking studies to target cyclooxygenase-2 enzyme.

1,3,4-Oxadiazole derivatives were screened for anti-inflammatory activity in carrageenan-induced rat paw edema and analgesic activity by tail immersion method.

In synthesized compounds, the free carboxylic group, which is responsible for gastric side effects, was derivatized by heterocyclic 1,3,4-oxadiazole bioactive core, which showed good interaction with COX-2 receptor with good docking score.

Among all the synthesized compounds, 4e and 4f have emerged out as potential COX-2 inhibitors.
