The design and synthesis of a new class of nonpeptide luteinizing hormone-releasing hormone (LHRH) receptor antagonists, the 2-phenylimidazo[1,2-a]pyrimidin-5-ones, is reported. Among compounds described in this study, we identified the potent antagonist 15b with nanomolar in vitro functional antagonism. The result might suggest that the heterocyclic 5-6-ring system possessing a pendant phenyl group
报道了新型的非肽黄体生成激素释放激素(LHRH)受体拮抗剂2-苯基咪唑并[1,2-a]嘧啶-5-酮的设计与合成。在这项研究中描述的化合物中,我们确定了具有纳摩尔体外功能拮抗作用的强效拮抗剂15b。结果可能表明,具有连接至五元环的苯基侧基的杂环5-6环系统是小分子LHRH拮抗剂支架的重要结构特征。
