Function

ACCC_ECOLI This protein is a component of the acetyl coenzyme A carboxylase complex; first, biotin carboxylase catalyzes the carboxylation of the carrier protein and then the transcarboxylase transfers the carboxyl group to form malonyl-CoA.

Publication Abstract from PubMed

The biotin carboxylase (AccC) is part of the multi-component bacterial acetyl coenzyme-A carboxylase (ACCase) and is essential for pathogen survival. We describe herein the affinity optimization of an initial hit to give 2-(2-chlorobenzylamino)-1-(cyclohexylmethyl)-1H-benzo[d]imidazole-5-carbox amide (1), which was identified using our proprietary Automated Ligand Identification System (ALIS).(1) The X-ray co-crystal structure of 1 was solved and revealed several key interactions and opportunities for further optimization in the ATP site of AccC. Structure Based Drug Design (SBDD) and parallel synthetic approaches resulted in a novel series of AccC inhibitors, exemplified by (R)-2-(2-chlorobenzylamino)-1-(2,3-dihydro-1H-inden-1-yl)-1H-imidazo[4,5-b ]pyridine-5-carboxamide (40). This compound is a potent and selective inhibitor of bacterial AccC with an IC(50) of 20 nM and a MIC of 0.8 microg/mL against a sensitized strain of Escherichia coli (HS294 E. coli).
