title: Use of amino acid N-carboxy anhydride in the synthesis of peptide prodrug derivatives (including beta-chloroalanyl) of C4-beta-aminoalkyl carbapenems. In vitro and in vivo activities.
abstract: Mono- and dipeptide derivatives of C4-beta-aminoalkyl carbapenems were synthesized by the use of amino acid N-carboxy anhydride for the peptide bond formation. They were shown to act as prodrugs in vivo while imparting the much desired chemical stability. The beta-chloroalanyl derivative was suggested to act, in part, as a "dual-purpose" antibacterial.
