the skeleton and can lead to osteoporosis. As 17β-hydroxysteroid dehydrogenase type 2 (17β-HSD2) catalyses the conversion between active 17β-hydroxysteroid estradiol (E2) and testosterone (T) into their less active 17-ketosteroid and has been found in bones, 17β-HSD2 inhibitor may provide a new approach in the onset of osteoporosis. Bicyclic substituted hydroxyphenylmethanone derivatives were synthesised
老年人E2缺乏症直接影响骨骼,并可能导致骨质疏松症。由于2型17β-羟基类固醇脱氢酶(17β-HSD2)催化活性17β-羟基类固醇雌二醇(E2)和睾丸激素(T)转变为活性较低的17-酮类固醇,并且已经在骨骼中发现,因此17β-HSD2抑制剂可能提供了骨质疏松症发作的新方法。合成双环取代的羟苯基甲酮衍生物作为底物E2的类固醇模拟物,并评估其对17β-HSD2的抑制作用及其对17β-HSD1的选择性,从而催化雌酮(E1)转化为E2的逆反应。高度选择性的化合物(11,12,14,21和22),最有前途的一个(12)表现出低纳摩尔范围(101 nM)的IC 50值,对17β-HSD1的选择性因子为13。这些结果使化合物12成为进一步生物学评估的有趣候选物。
