Biological Activity for CP 154526

CP 154526 is a selective, non-peptide CRF1 receptor antagonist (Ki values are 2.7 and > 10000 nM for CRF1 and CRF2 receptors respectively). Blocks CRF-induced adenylate cyclase activation (Ki = 3.7 nM) and attenuates activation of the HPA axis by CRF. Displays anxiolytic-like activity in the rat elevated plus-maze test; brain penetrant.
