Identification of (R)-(2-Chloro-3-(trifluoromethyl)phenyl)(1-(5-fluoropyridin-2-yl)-4-methyl-6,7-dihydro-1H-imidazo[4,5-c]pyridin-5(4H)-yl)methanone (JNJ 54166060), a Small Molecule Antagonist of the P2X7 receptor

The synthesis and SAR of a series of 4,5,6,7-tetrahydro-imidazo[4,5-c]pyridine P2X7 antagonists are described. Addressing P2X7 affinity and liver microsomal stability issues encountered with this template afforded methyl substituted 4,5,6,7-tetrahydro-imidazo[4,5-c]pyridines ultimately leading to the identification of 1 (JNJ 54166060). 1 is a potent P2X7 antagonist with an ED50 = 2.3 mg/kg in rats, high oral bioavailability and low-moderate clearance in preclinical species, acceptable safety margins in rats, and a predicted human dose of 120 mg of QD. Additionally, 1 possesses a unique CYP profile and was found to be a regioselective inhibitor of midazolam CYP3A metabolism.

We report the structure-based design and synthesis of a novel series of aza-benzimidazoles as PHD2 inhibitors. These efforts resulted in compound 22, which displayed highly potent inhibition of PHD2 function in vitro.
