inhibit steroid sulfatase activity may be a rewarding approach to the treatment of androgeno-sensitive and estrogeno-sensitive diseases. In the present study, we report the chemical synthesis and biological evaluation of a new family of steroid sulfatase inhibitors. The inhibitors were designed by adding an alkyl, a phenyl, a benzyl, or a benzyl substituted at position 17alpha of estradiol (E(2)), a C18-steroid
类固醇硫酸酯酶或甾基硫酸酯酶是广泛分布在人体组织中的微粒体酶,其催化硫酸化的3-羟基类固醇水解为相应的游离活性3-羟基类固醇。由于雄激素和雌激素可能是从血液中可用的脱氢表雄酮硫酸盐(DHEAS)和硫酸雌酮(E(1)S)开始在癌细胞内合成的,因此使用抑制类固醇硫酸酯酶活性的治疗剂可能是一种有益的方法。雄激素敏感性和雌激素敏感性疾病的治疗。在本研究中,我们报告了甾族硫酸酯酶抑制剂新家族的化学合成和生物学评估。通过添加在C18类固醇的雌二醇(E(2))的17α位上取代的烷基,苯基,苄基或苄基来设计抑制剂 使用均质的JEG-3细胞或转染到HEK-293细胞中的类固醇硫酸酯酶进行酶分析。我们观察到,疏水取代基可强烈抑制类固醇硫酸酯酶,而亲水取代基则较弱。尽管在17α-位的疏水基团增加了抑制活性,但位阻因素却起到了相反的作用。如17alpha-decyl-E(2)和17alpha-dodecyl-E(
