The design, synthesis, and biological evaluation of a series of new aromatase (AR, CYP19) inhibitors bearing an imidazole ring linked to a 7-substituted coumarin scaffold at position 4 (or 3) are reported. Many compounds exhibited an aromatase inhibitory potency in the nanomolar range along with a high selectivity over 17-α-hydroxylase/C17−20 lyase (CYP17). The most potent AR inhibitor was the 7-(3
报道了一系列新的芳香酶(AR,CYP19)抑制剂的设计,合成和生物学评估,这些抑制剂带有与7位取代的香豆素骨架连接的4位(或3位)咪唑环。许多化合物在纳摩尔浓度范围内均显示出芳香化酶抑制潜能,并且对17-α-羟化酶/ C17-20裂解酶(CYP17)具有较高的选择性。最有效的AR抑制剂是7-(3,4-二氟苯氧基)-4-咪唑基甲基香豆素24,IC 50 = 47 nM。在一定数量的香豆素衍生物上的对接模拟可以识别驱动结合的最重要的相互作用,并清楚地表明香豆素和紧密相关的杂环分子支架的适当结构修饰的允许和不允许的区域。
