What is CHIR-090?

Description

CHIR-090 is the first reported compound that in fact kills both E. coli and Pseudomonas aeruginosa in bacterial disk diffusion assays (Liang et al. 2011). Nonetheless, CHIR-090 was about 600-fold less effective against LpxC orthologs from the Rhizobiaceae family than against E. coli LpxC. In this way, studies have shown that the removal of morpholine ring, based on a chemical scaffold of reduced radius, was able to increase affinity by 20-fold for LpxC enzymes from the Rhizobiaceae family of bacteria and enhance the antibiotic activity against E. coli and P. aeruginosa by 2–4 fold over CHIR-090.

Definition

ChEBI: CHIR-090 is an L-threonine derivative obtained by formal condensation of the carboxy group of 4-({4-[(morpholin-4-yl)methyl]phenyl}ethynyl)benzoic acid with the amino group of N-hydroxy-L-threoninamide. It has a role as an antimicrobial agent, a lipopolysaccharide biosynthesis inhibitor and an EC 3.5.1.108 (UDP-3-O-acyl-N-acetylglucosamine deacetylase) inhibitor. It is an acetylenic compound, a member of morpholines, a member of benzamides, a L-threonine derivative and a hydroxamic acid.
