Fosmidomycin analogues as inhibitors of monoterpenoid indole alkaloid production in Catharanthus roseus cells
Substituted 3-[2-(diethoxyphosphoryl)propyl]oxazolo[4,5-b]pyridine-2(3H)-ones were obtained by functionalization at 6-position with various substituents (aryl, vinyl, carbonyl chains) via reactions catalysed with palladium. We found that these new fosmidomycin analogues inhibited the accumulation of ajmalicine, a marker of monoterpenoid indole alkaloids production in plant cells. Some of them have

Compounds having the formula ##STR1## wherein R.sup.1 is a acyl, R.sup.2 is hydrogen, lower alkyl, ar(lower)alkyl or acyl, and A is lower alkylene, lower alkenylene or hydroxy(lower)alkylene, or an agronomically-acceptable salt or ester thereof, are herbicidally active.
Studies on phosphonic acid antibiotics. IV. Synthesis and antibacterial activity of analogs of 3-(N-acetyl-N-hydroxyamino)-propylphosphonic acid (FR-900098).
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.
Studies on phosphonic acid antibiotics. I. Structure and synthesis of 3-(n-acetyl-n-hydroxyamino)propylphosphonic acid (FR-900098) and its n-formyl analogue (FR-31564)
The structure elucidation of FR-900098 (1) isolated from a microorganism source and the syntheses of FR-900098 and its N-formyl analogue, FR-31564 (2), are described. The latter possesses a superior antimicrobial activity.
