An efficient and practical method for solid-phase synthesis of tripeptide-bearing glycopeptide antibiotics: combinatorial parallel synthesis of carboxamide derivatives of chloroorienticin B

Abstract

An efficient and practical method was established for solid-phase parallel synthesis of the peptide-bearing carboxamide derivatives of chloroorienticin B, and over 80 compounds were synthesized simultaneously. Among the derivatives prepared, compounds having both tryptophan and tyrosine residues ( 1– 3) were found to possess potent antibacterial activity against VRE.
