4-Aminothiazolyl analogues of GE2270 A: antibacterial lead finding

Abstract

4-Aminothiazolyl analogues of the antibacterial natural product GE2270 A (1) were designed, synthesized, and evaluated for gram positive bacteria growth inhibition. The aminothiazole-based chemical template was evaluated for chemical stability, and its decomposition revealed a novel, structurally simplified, des-thiazole analogue of 1. Subsequent stabilization of the 4-aminothiazolyl functional motif was achieved and initial structure activity relationships defined.
