Biological Activity for NBI 35965 hydrochloride

NBI 35965 hydrochloride is a potent and selective corticotropin-releasing factor receptor 1 (CRF₁) antagonist (K_i values are 4 and > 10000 nM at CRF₁ and CRF₂ respectively). Inhibits cAMP accumulation and adrenocorticotropic hormone (ACTH) production in vitro (pIC₅₀ values are 7.1 and 6.9 respectively) and attenuates CRF and ACTH production in vivo. Orally active and brain penetrant with anxiolytic activity.
