title: Pyrimidinone antibiotics--heterocyclic analogues with improved antibacterial spectrum.
abstract: We report the synthesis and pharmacological evaluation of new derivatives of the natural dipeptide antibiotic TAN 1057 A,B containing heterocycles either in the beta-amino acid side chain or as mimics of the urea function. In the course of this program, we identified novel analogues that display activity towards a broader panel of Gram-positive bacteriae.
