Biochem/physiol Actions

BMS-763534 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 = 0.26 & 0.4 nM against 150 pM ovine CRF for binding rat & human CRF-R1, respectively), potency (IC50 = 1.0 nM against 0.3 nM CRF-stimulated ATCH secretion from primary rat anterior pituitary cells), and selectivity, displaying little affinity toward porcine CRF-R2/CRF2 and 46 other receptor/channel/transporter proteins (IC50 >10 μM). BMS-763534 inhibits CRF-stimulated cAMP production in human Y-79 retinoblastoma cells in cultures (pA2 = 9.47) and exhibits anxiolytic efficacy in a rat situational anxiety model in vivo (0.5-3 mg/kg p.o.).

BMS-763534 is a potent (CRF(1) IC(50) = 0.4 nM) and selective (>1000-fold selectivity vs. all other sites tested) CRF(1) receptor antagonist (pA2 = 9.47 vs. CRF(1)-mediated cAMP production in Y79 cells). BMS-763534 accelerated the dissociation of (125)I-o-CRF from rat frontal cortex membrane CRF(1) receptors consistent

A series of N(3)-pyridylpyrazinones was investigated as corticotropin-releasing factor-1 receptor antagonists. It was observed that the binding affinity of analogues containing a pyridyl group was influenced not only by the substitution pattern on the pyridyl group, but also by the

Detailed metabolic characterization of 8, an earlier lead pyrazinone-based corticotropin-releasing factor-1 (CRF(1)) receptor antagonist, revealed that this compound formed significant levels of reactive metabolites, as measured by in vivo and in vitro biotransformation studies. This was of particular concern due
