breast cancer. In this paper, we report the design, synthesis, and in vitro biological evaluation of a series of new (di)benzopyranone-based inhibitors of this enzyme. The design of the new compounds was guided by a CoMFA model previously developed for a series of nonsteroidal aromatase inhibitors. Both the chromone and the xanthone nuclei were taken as molecular skeletons, and the functions supposed to
芳香酶(P450arom)是治疗乳腺癌的药理学目标。在本文中,我们报告了该酶的一系列新型(二)苯并吡喃酮类抑制剂的设计,合成和体外生物学评估。新化合物的设计以先前针对一系列非甾体芳香酶抑制剂开发的CoMFA模型为指导。色酮和黄嘌呤核均被视为分子骨架,其功能对于结合芳香酶活性位点至关重要-通过亚甲基与芳香部分相连的杂环(咪唑或1,3,4-三唑)单元和一个H键接受功能(CN,NO(2),Br)位于芳环上,与带有孤对的杂环氮相距合适的距离-并与它们相连。色酮,蒽酮,黄酮衍生物和黄酮衍生物通过常规合成方法由适当的甲基类似物制备。使用人胎盘微粒体和[1β,2β-(3)H]睾丸激素作为标记底物,通过Thompson和Siiteri的方法确定芳香酶抑制活性。还对所有化合物进行了17α-羟化酶/ C17,20-裂合酶(P450 17)的测试,这是一种治疗前列腺疾病的具有治疗意义的酶。x吨酮衍生物22d,e(IC(50)值分别为43和40
