BMS-665053 is a pyrazinone-containing antagonist that targets corticotropin-releasing factor/hormone (CRF or CRH) receptor 1 (CRF1, CRF-R1, CRFR-1, CRH-R1, CRHR-1) with high affinity (IC50 </= 1.0 nM against 150 pM ovine CRF for binding human and rat CRF-R1), potency (IC50 = 4.9 nM against 1 nM CRF-stimulated cAMP production in human Y-79 retinoblastoma cells), and selectivity, displaying no affinity toward CRF-R2/CRF2 (IC50 >10 μM against 150 pM ovine CRF in binding assay). BMS-665053 exhibits anxiolytic efficacy in a defensive withdrawal anxiety test in rats in vivo (10 mg/kg p.o.) with good oral bioavailability (F = 52%).

(S)-5-Chloro-1-(1-cyclopropylethyl)-3-(2,6-dichloro-4-(trifluoromethyl)phenylamino)pyrazin-2(1H)-one (BMS-665053), a pyrazinone-containing compound, is a potent and selective antagonist of corticotropin-releasing factor receptor-1 (CRF-R1) that showed efficacy in the defensive withdrawal model for anxiety in rats, suggesting its use as a potential treatment for anxiety and depression. In
A series of 5-arylamino-1,2,4-triazin-6(1H)-ones was synthesized and evaluated as antagonists at the corticotropin releasing factor receptor. Formation of CYP-mediated oxidative reactive metabolites previously observed in a related N(3)-phenylpyrazinone structure was minimized by incorporation of the additional ring nitrogen found in
Journal of medicinal chemistry, 52(14), 4161-4172 (2009-06-26)
A series of pyrazinone-based heterocycles was identified as potent and orally active corticotropin-releasing factor-1 (CRF(1)) receptor antagonists. Selected compounds proved efficacious in an anxiety model in rats; however, pharmacokinetic properties were not optimal. In this article, we describe an in
