ω-(2-Amino-2-carboxyethylthiol-2-(cyclopropane- carboxamido)-2-alkenoic acids, their esters and salts of the formula
in the Z configuration, wherein R2 is 2,2-dimethylcyclopropyl or 2,2-dichlorocyclopropyl; R' is hydrogen, loweralkyl of 1-6 carbon atoms, dialkylaminoalkyl with 1-6 carbon atoms in each alkyl group, or a pharmaceutically acceptable cation; R3 is an alkylene chain of 3-7 carbon atoms, having a terminal substituent which is 2-amino-2-carboxyethylthio, or 1-(phosphono)ethylamino which selectively inhibit the metabolism of dipeptidase (E.C:3.4.13.11) and therefore are useful in combination with antibacterial products, by preference with the thienamycin class of compounds.
