Estradiol-3,17-O,O-bis-sulfamates inhibit steroid sulfatase (STS), carbonic anhydrase (CA), and, when substituted at C-2, cancer cell proliferation and angiogenesis. C-2 Substitution and 17-sulfamate replacement of the estradiol-3,17-O,O-bis-sulfamates were explored with efficient and practical syntheses developed. Evaluation against human cancer cell lines revealed the 2-methyl derivative 27 (DU145
雌二醇3,17-O,O-双-氨基磺酸盐抑制类固醇硫酸酯酶(STS),碳酸酐酶(CA),并在被C-2取代时抑制癌细胞的增殖和血管生成。探索了C-2取代和17-氨基磺酸雌二醇-3,17-O,O-双-氨基磺酸盐的替代方法,并开发了有效而实用的合成方法。对人类癌细胞系的评估显示,2-甲基衍生物27(DU145 GI(50)= 0.38 microM)是最活跃的新型双氨基磺酸盐,而2-乙基-17-氨基甲酸酯衍生物52(GI(50)= 0.22 microM) )被证明是其系列中最活跃的(参见2-ethylestradiol-3,17-O,O-bis-sulfamate 4 GI(50)= 0.21 microM)。较大的C-2取代基对活性有害。X射线晶体学研究了2-甲氧基17-氨基甲酸酯50,与母体双氨基磺酸酯3相比,作为STS抑制剂的出奇地弱13倍。使用乳腺癌和前列腺癌异种移植物证实了4作为口服抗
