1-(1H-Benzimidazol-5-yl)-3-tert-butylurea derivatives have been identified as a novel class of non-peptide luteinizing hormone-releasing hormone (LHRH) antagonists. Herein, we disclose the synthesis and structure-activity relationships (SAR) of this class resulting in the identification of compound 12c, with dual functional activity on human and rat receptors (rat LHRH: IC50=120 nM; human LHRH: IC50=18
1-(1H-苯并咪唑-5-基)-3-叔丁基脲衍生物已被确定为一类新型的非肽黄体生成激素释放激素(LHRH)拮抗剂。本文中,我们披露了此类化合物的合成与构效关系(SAR),从而鉴定出对人和大鼠受体具有双重功能的化合物12c(大鼠LHRH:IC50 = 120 nM;人LHRH:IC50 = 18 nM )。这些SAR研究表明1-(1H-苯并咪唑-5-基)-3-叔丁基脲是小分子LHRH拮抗剂的新药效团。
