activation of the estrogen receptor alpha (ERalpha). 17beta-Hydroxysteroid dehydrogenase type 1 (17beta-HSD1), which is responsible for the catalytic reduction of the weakly active estrogen estrone (E1) into E2, is therefore discussed as a novel drug target. Recently, we have discovered a 2,5-bis(hydroxyphenyl) oxazole to be a potent inhibitor of 17beta-HSD1. In this paper, further structural optimizations were
最有效的女性性激素17beta-Estradiol(E2)通过激活雌激素受体α(ERalpha)刺激乳腺肿瘤的生长和子宫内膜异位症。因此,将17beta-羟基类固醇脱氢酶1型(17beta-HSD1)负责将弱活性雌激素雌酮(E1)催化还原为E2,作为一种新型药物靶标进行了讨论。最近,我们发现2,5-双(羟苯基)恶唑是17beta-HSD1的有效抑制剂。在本文中,进行了进一步的结构优化:合成了39个双(羟基苯基)唑,噻吩,苯和氮杂苯,并对其生物学特性进行了评估。这项研究最有前途的化合物显示出在低纳摩尔范围内提高的IC 50值,对17beta-HSD2的高选择性,对ERalpha的低结合亲和力,在大鼠肝微粒体中具有良好的代谢稳定性,并且经口应用后具有合理的药代动力学特征。分子静电势的计算揭示了17beta-HSD1抑制与电子密度分布之间的相关性。
