Studies on Phosphonic Acid Antibiotics. IV. Synthesis and Antibacterial Activity of Analogs of 3-(N-Acetyl-N-hydroxyamino)-propylphosphonic Acid (FR-900098)

Abstract

The synthesis of analogs of 3-(N-acetyl-N-hydroxyamino) propylphosphonic acid (FR-900098, Ia) and an analysis of their structure-activity relationship are described. Among them, compounds Ib (FR-31564) and XIIb (FR-32863) have recently been found to be produced naturally by Streptomyces lavendulae. The antibacterial activity of Ib against Pseudomonas species is especially significant.
