Design, synthesis, and structure–activity relationships of pyrazole derivatives as potential FabH inhibitors
摘要:
Fatty acid biosynthesis is essential for bacterial survival. 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 - \negative bacteria. Fifty-six 1-acetyl-3,5-diphenyl-4,5-dihydro-(1H)-pyrazole derivatives were synthesized and developed as potent inhibitors of FabH. This inhibitor class demonstrates strong antibacterial activity. Escherichia coli FabH inhibitory assay and docking simulation indicated that the compounds 1-(5-(4-fluorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl) ethanone (12) and 1-(5-(4-chlorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl) ethanone (13) were potent inhibitors of E. coli FabH.

The translation of functionally active naturalproducts into fully synthetic small-molecule mimetics has remained an important process in medicinal chemistry. We recently discovered that the terpene naturalproduct nimbolide can be utilized as a covalent recruiter of the E3 ubiquitin ligase RNF114 for use in targeted protein degradation—a powerful therapeutic modality within modern-day drug discovery
