Z-omega-substituted thio-2-(2,2-dimethylcyclopropanecarboxamido)-2-alkenoic acids, a process for preparing and an antibacterial composition containing the same.

摘要

Novel chemical compounds and a process for preparing them are provided. These compounds selectively inhibit the metabolism of dipeptidase (E.C.3.4.13.11) and therefore are useful in combination with antibacterial products. These chemical compounds are Z-2-(2,2-dimethylcyclopropanecarboxamido)- omega -pyridylthio-2-alkenoic acids (and related arylthio and heterocyclylthio analogs) of the general formula: <CHEM> wherein n is an integer from 3-5, Y is pyridyl, pyrimidinyl, tetrazolyl, imidazolyl, thiadiazolyl, thiazolinyl, or phenyl, optionally having 1 or 2 substituents which are hydroxyl, oxo, carboxyl, or methyl; and the loweralkyl (C1-6) esters and pharmaceutically acceptable salts thereof.
