[Amino acid derivatives of 2,6-xylidine and p-aminobenzoic acid. II. Synthesis of derivatives of N-(p-aminobenzoylaminoalkylacyl)-2,6-xylidines and study of their resistance to proteolytic factors].

Abstract

Syntheses of N-(p-aminobenzoylaminoalkylacyl)-2,6-xylidines are described. The carbodiimide method and the method of mixed anhydrides were employed for the syntheses. Physicochemical properties, yields, data of elementary analysis and IR spectra of eighteen novel compounds are given. Resistance of some obtained compounds to actions of the gastric digestive… (More)
