CP-640186 hydrochloride

CP-640186 hydrochloride has been used as an allosteric acetyl-CoA carboxylase (ACC) inhibitor (ACCi) for pharmacological inhibition of lipogenesis to determine if fatty acid synthesis is essential for brown adipose tissue (BAT) whitening. It has also been used as an inhibitor of mammalian acetyl-CoA carboxylase (mACC1/2) to study its effect on meropenem potency against the persisters from multiple pathogens, including B. thailandensis, P. aeruginosa, S.Typhimurium, and attenuated Y. pestis.

CP-640186 is a potent and orally active acetyl-CoA carboxylase 1/2 (ACC-alpha/beta, ACC1/2) inhibitor (IC50 ~50 nM) that targets the carboxyltransferase (CT) domain at the ACC dimer interface (via tight interactions with the putative biotin-binding site) in a reversible manner, uncompetitive with respect to ATP, and non-competitive with respect to bicarbonate, acetyl-CoA, and citrate. CP-610431 inhibits fatty acid (FA) synthesis, triglyceride (TG) synthesis, TG and apoB secretion (IC50 = 1.6, 1.8, 3.0, and 5.7 μM, respectively), but not cholesterol synthesis or apoC3 secretion in HepG2 cells (ACC1), as well as stimulates FA oxidation in C2C12 cells (ACC2) and in rat epitrochlearis muscle strips (EC50 = 57 nM and 1.3 μM, respectively). Oral administration is shown to inhibit FA synthesis in rats, CD1 mice, and ob/ob mice (ED50 = 13, 11, and 4 mg/kg, respectively) and stimulate rat whole body FA oxidation (ED50 ∼30 mg/kg) in vivo.
