Design, synthesis, and structure-activity relationships of thieno[2,3-b]pyridin-4-one-based non-peptide luteinizing hormone-releasing hormone (LHRH) receptor antagonists are described. Starting with the thienopyridin-4-one derivative 26d (T-98475) an optimization study was performed, which resulted in the identification of a highly potent and orally bioavailable LHRH receptor antagonist, 3-(N-benz
设计,合成,和构效关系的基于thieno [2,3-b] pyridin-4-one的非肽黄体生成激素释放激素(LHRH)受体拮抗剂。从噻吩并吡啶-4-酮衍生物26d(T-98475)开始,进行了优化研究,从而确定了一种高效且可口服生物利用的LHRH受体拮抗剂3-(N-苄基-N-甲基氨基甲基)-7 -(2,6-二氟苄基)-4,7-二氢-2- [4-(1-氢xy-1-环丙烷羧酰胺基)苯基] -5-异丁酰基-4-氧噻吩并[2,3-b]吡啶(33c )。化合物33c显示出对人受体的亚纳摩尔体外活性,并且其口服给药有效地抑制了cast割的雄性食蟹猴的血浆LH水平。此外,
