Synthesis, physicochemical characterization and pharmacological evaluation of mutual prodrugs of aceclofenac with quercetin, vanillin and L-tryptophan have been attempted to develop novel gastrosparing NSAIDs, devoid of ulcerogenic side effects. The structures of synthesized prodrugs were confirmed by IR, H-1 NMR, C-13 NMR and mass spectroscopy. The hydrolysis kinetics studies were performed in simulated gastric fluid, simulated intestinal fluid and rat fecal matter. Its anti-inflammatory and ulcer index were analyzed along with estimation of biochemical parameters (GWM and Hexosamine), oxidative parameters (LPO, GSH, CAT, and SOD) and protein estimation. The results indicated that the synthesized prodrugs are chemically stable, biolabile and possesses optimum lipophilicity. They also exhibited retention of anti-inflammatory activity with reduced ulcerogenicity. The study showed that the mutual prodrugs are better in action compared to the parent drug and have fewer gastrointestinal side effects.

Microwave assisted amberlite-IRA-402 (OH) ion exchange resin catalyzed synthesis of new benzoxazole scaffolds derived from antiinflammatory drugs aceclofenac and mefenamic acid as potential therapeutic agents for inflammation
microwave assisted synthesis of 2-substituted benzoxazole derivatives from antiinflammatory drugs aceclofenac and mefenamic acid using amberlite-IRA-402 (OH) ion exchange resin as a base catalyst were reported. The synthesized compounds were purified and characterized by 1H NMR, 13C NMR and Mass spectroscopy. In silico molecular docking studies were carried out to predict the bindingaffinity of the synthesized
