The synthesis and SAR studies of tricyclic imidazo[4,5-b]pyridin-2-ones as human corticotropin-releasing factor receptor (CRF(1)) antagonists are discussed herein. Compound 16g was identified as a functional antagonist that inhibited CRF-stimulated cyclic adenosine monophosphate production and CRF-induced adrenocorticotrophic hormone release. Pharmacokinetics studies in rats showed that 16g was orally
本文讨论了三环咪唑并[4,5-b]吡啶-2-酮作为人类促肾上腺皮质激素释放因子受体(CRF(1))拮抗剂的合成和SAR研究。化合物16g被确定为一种功能性拮抗剂,可抑制CRF刺激的环磷酸腺苷生成和CRF诱导的肾上腺皮质营养激素释放。在大鼠体内进行的药代动力学研究表明,16g口服生物可利用的,具有良好的脑部渗透能力,并且半衰期适中。在我们努力确定具有改善的药代动力学特性的CRF(1)拮抗剂的过程中,16g的药物显示出较低的分布体积。
