Design, synthesis and biological evaluation of urea derivatives from o-hydroxybenzylamines and phenylisocyanate as potential FabH inhibitors
摘要:
FabH, beta-ketoacyl-acyl carrier protein (ACP) synthase III, is a particularly attractive target, since it is central to the initiation of fatty acid biosynthesis and is highly conserved among Gram-positive and Gram-negative bacteria. A series of o-hydroxybenzylamines 1-16 and its corresponding new urea derivatives 17-32 were synthesized and fully characterized by spectroscopic methods and elemental analysis. This new urea derivatives class demonstrates strong antibacterial activity. Escherichia coli FabH inhibitory assay and docking simulation indicated that the compounds 1-(5-bromo-2-hydroxybenzyl)-1-(4-fluorophenyl)-3-phenylurea (18) and 1-(5-bromo-2-hydroxybenzyl)-1-(4-chlorophenyl)-3-phenylurea (20) were potent inhibitors of E. coli FabH.

A dosage regimen for the topical prevention or treatment of a skin infection or an inflammatory skin condition in a human subject using a halogenated salicylanilide. The topical dosage regimen provides high concentrations of the halogenated salicylanilide in skin tissue which are retained for a prolonged period without the need for further topical dosing of the halogenated salicylanilide.
