Here we describe the properties of CP-154,526, a potent and selective nonpeptide antagonist of corticotropin (ACTH) releasing factor (CRF) receptors. CP-154,526 binds with high affinity to CRF receptors (Ki < 10 nM) and blocks CRF-stimulated adenylate cyclase activity in membranes prepared from rat cortex and pituitary. Systemically administered CP-154,526(More)
SR141716A (Sanofi Recherche), a pyrazole derivative with high affinity for rat and human CB1 cannabinoid receptors, has recently been reported to reverse biochemical, physiological and behavioral effects induced by cannabinoid agonists. The present experiments characterized the activity of SR141716A (SR) in behavioral procedures designed to assess its(More)
An orally active clinical candidate of corticotropin-releasing factor 1 (CRF 1) antagonist 1 showed a significant positive food effect in dog and human after oral administration. Efforts to address the food effect issue led us to explore and discover compounds in series 2 as orally active CRF 1 receptor antagonists, in which some compounds showed improved(More)
A series of 2-aryloxy-4-alkoxy-pyridines ( 1) was identified as novel, selective, and orally active antagonists of the corticotropin-releasing factor 1 (CRF 1) receptor. Among these, compound 2 (CP-316311) is a potent and selective CRF 1 receptor antagonist with an IC 50 value of 6.8 nM in receptor binding and demonstrates oral efficacy in central nervous(More)
