title: Modification of the cysteamine side chain of thienamycin. III.
abstract: Thienamycin derivatives (4) having a cyclic amidine moiety at the C-2 position were prepared. The susceptibility to renal dehydropeptidase-1 and the antimicrobial activity of these compounds were determined. Their structure-activity relationships are also discussed.
