- Microwave-assisted one-step synthesis of fenamic acid hydrazides from the corresponding acids
-
A facile and efficient method for synthesis of fenamic acid hydrazides from their acids in one-step reaction under microwave irradiation and solvent-free conditions was developed. Compared with the two-step conventional heating method, the process was simple, the reaction time was very short and the yields were almost quantitative.

- Synthesis, analgesic and anti-inflammatory activities of chalconyl-incorporated hydrazone derivatives of mefenamic acid
-
A series of chalconyl-incorporated hydrazone derivatives of mefenamic acid was synthesized in order to obtain new compounds with potential analgesic and anti-inflammatory activity having lesser side effects. The structures of all synthesized compounds were confirmed by means of elemental analysis, IR, 1H NMR, 13C NMR and mass spectra. All compounds were evaluated for their analgesic and anti-inflammatory activities by tail-flick method and carrageenan-induced rat paw edema test, respectively. Among all the synthesized compounds, compounds (4a) and (4j) exhibited the most prominent and consistent anti-inflammatory activity. In acute ulcerogenicity study, it can be concluded that compounds (4a) and (4j) are devoid of the deadlier gastrointestinal toxicities.

- New esters of N arylanthranilic acids
-
A series of acyloxy and alkyloxymethyl esters of meclofenamic, flufenamic and mefenamic acids has been synthesized and its antiinflammatory, analgesic and antipyretic activities have been compared with those of the corresponding acids and the methyl, β,γ isopropylidenedioxypropyl, and N,N diethylaminoethyl esters. The acyloxy and alkyloxymethyl esters are the most interesting compounds, because they possess pharmacological activity of the same order as that of the corresponding acids and a lower toxicity. The ethoxymethyl ester of N (2,6 dichloro m tolyl)anthranilic acid is presently under clinical investigation.
