The pre-clinical characterization of novel aryloxypyridine amides that are histamine H(3) receptor antagonists is described. These compounds are high affinity histamine H(3) ligands that penetrate the CNS and occupy the histamine H(3) receptor in rat brain. Several compounds were extensively profiled pre-clinically leading to the identification of two(More)
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(More)
Previous research on histamine H(3) antagonists has led to the development of a pharmacophore model consisting of a central phenyl core flanked by two alkylamine groups. Recent investigation of the replacement of the central phenyl core with heteroaromatic fragments resulted in the preparation of novel 3,5-, 3,6- and 3,7-substituted indole and(More)
Pre-clinical characterization of novel substituted pyrrolidines that are high affinity histamine H(3) receptor antagonists is described. These compounds efficiently penetrate the CNS and occupy the histamine H(3) receptor in rat brain following oral administration. One compound,(More)
