variety of N-[(ethyl-4,6-diaryl-3-pyridinecarboxylate)-2-yl]aminoacidesters 6a-h were synthesized through the reaction of 2-bromonicotinates 4 with a number of primary aminoacidester hydrochlorides 5 in refluxing tetrahydrofuran in the presence of triethylamine as dehydrohalogenating agent. Similarly, reaction of 4 with N-glycylglycine ethyl ester hydrochloride 7 'as a representative example of dipeptide

A focused dataset of previously synthesized and tested [1,2,4]-triazolo[1,5-a]pyridines and pyridine-3-carboxylates was studied by Molecular Field Topology Analysis (MFTA) to identify steric and electronic determinants of anti-inflammatory activity useful for the design and synthesis of new anti-inflammatory agents. Rational design based on the MFTA model identified eleven novel pyridine-3-carboxylates (2a-e and 3a-f) as promising. After synthesis and screening, three of (2a, 2c, 3a) revealed potent anti-inflammatory activity exceeding that of indomethacin, the reference inhibitor for artificially induced edema in rats.
