Design, synthesis and structure-activity relationship evaluation of novel LpxC inhibitors as Gram-negative antibacterial agents was written by Ding, Shi;Dai, Rui-Yang;Wang, Wen-Ke;Cao, Qiao;Lan, Le-Fu;Zhou, Xian-Li;Yang, Yu-She. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2018.Name: Methyl 4-bromo-2-fluorobenzoate This article mentions the following:
LpxC inhibitors are new-type antibacterial agents developed in the last twenty years, mainly against Gram-neg. bacteria infections. To develop novel LpxC inhibitors with good antibacterial activities and biol. metabolism, the authors summarized the basic skeleton of reported LpxC inhibitors, designed and synthesized several series of compounds and tested their antibacterial activities against Escherichia coli and Pseudomonas aeruginosa in vitro. Structure-activity relations are discussed. The metabolism stability of YDL-2, YDL-5, YDL-8, YDL-14, YDL-20-YDL-23 were evaluated in liver microsomes, which indicated that the 2-amino iso-Pr group may be a preferred structure than the 2-hydroxy Et group in the design of LpxC inhibitors. In the experiment, the researchers used many compounds, for example, Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2Name: Methyl 4-bromo-2-fluorobenzoate).
Methyl 4-bromo-2-fluorobenzoate (cas: 179232-29-2) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. Many of the alkyl bromine derivatives are excellent alkylating agents since bromides are good leaving groups. Tribromides, like tetrabutylammonium tribromide, are used as a solid source of bromine. N-bromosuccimide (NBS) is used for the selective bromination of allylic bonds.Name: Methyl 4-bromo-2-fluorobenzoate
