Abstract

Abstract Aromatic amide derivatives of formula (I) and their salts are new. (Where R1 = aliphatic hydrocarbon optionally substituted with halogen or OH, or a cycloaliphatic or araliphatic hydrocarbon. X1 = CO, SO2, or OCO with the carbon linked to the N. X2 = aliphatic hydrocarbon (optionally substituted with OH, carboxy, NH2, guanidino, cycloaliphatic or aromatic hydrocarbon) or cycloaliphatic hydrocarbon, with a carbon of the aliphatic optionally bridged by a divalent aliphatic hydrocarbon. R2 = carboxy or its ester or amide derivative, NH2, substituted amino, formyl, acetal derivative of formyl, 1H-tetrazol-5-yl, pyridyl, OH, ether, SR, SOR, SO2R, alkanoyl, sulphamoyl, N-substituted sulphamoyl, PO2H2 or PO3H2. R = H or aliphatic hydrocarbon. X3 = hydrocarbon. R3 = carboxy, 5-tetrazolyl, SO3H, PO2H2, PO3H2 or haloalkylsulphamoyl. Rings A and B are each optionally substd. 121 compounds are specifically claimed, including (S)-N-(1-carboxy -2-methyl)-prop-1-yl) -N-pentanoyl-N- (2'-(1H-tetrazol-5-yl) biphenyl-4-ylmethyl) amine.
