ABSTRACT:

The synthesis of different 2,3-pyridine dicarboxamino acids (II-XI), 2,3-pyridine-dicarbox-Gly OMe, HCI (XII), hydrazides (XIII, XIV), dipeplide methyl esters (XV-XVIII) and aminoacylamides (XIX-XXIII) are described. Coupling of quinolinic acid-3-methyl ester with amino acid methyl ester hydrochlorides in dioxane-Et3N medium using the dicyclohexylcarbodiimide (DCC method furnishes the desired nicotinic acid methyl ester -2-carbonyl-amino acid methyl esters (XXV-XXIX). Twelve of the synthesized 2,3-pyridine dicarboxamino acids (II -XI) and the hydrazides (XIII, XIV) were found to be active against a number of microorganisms. Compounds (III and IV) were reported to possess some analgesic properties.
