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) are produced naturally by Streptomyces lavendulae. The antibacterial activity of Ib against Pseudomonas sp. is especially significant.
