  Structure–Activity Relationships of C-17-Substituted Estratriene-3-O-sulfamates as Anticancer Agents

  摘要：

  The synthesis and antiproliferative activities of analogues of 2-substituted estradiol-3,17-O,O-bis-sulfamates (E2bisMATEs) are discussed. Modifications of the C-17 substituent confirm that an H-bond acceptor is essential for high activity; its optimal linkage to C-17 and the local environment in which it resides are defined. In the non-sulfamoylated series 17 beta-acyl substitution delivers 48b, the most potent compound identified to date. In the sulfamate series a number of permutations of linker and H-bond acceptor deliver excellent activity, with 55, 61, 65, 49a, and 49b proving especially promising. The in vivo potential of these compounds was explored in the NCI hollow fiber assay and also in a mouse Matrigel model of antiangiogenesis in which 49 and 55 show significant inhibitory activity.

  vitro. Investigation of the SAR reveals that a sterically unhindered hydrogen bond acceptor attached to C-17 is most likely key to the enhanced activity. Compound 8 displayed significant in vitro antiangiogenic activity, and its ability to act as a microtubule disruptor was confirmed. Inhibitory activity of the sulfamate derivatives against steroid sulfatase and carbonic anhydrase II (hCAII) was also

  讨论了17-氰基2-取代的estra-1,3,5（10）-三烯作为抗癌剂的合成，SAR和临床前评价。2-甲氧基17β-氰基甲基estra-1,3,5（10）-三烯-3-醇（14），但没有相关的2-乙基衍生物7和相关的3-O-氨基磺酸盐8和15显示出有效的抗增殖作用（分别针对MCF-7 GI 50 300、60和70 nM）对人癌细胞的抗癌作用。对SAR的研究表明，连接C-17的空间不受阻碍的氢键受体很可能是增强活性的关键。化合物8显示出显着的体外抗血管生成活性，并证实了其充当微管破坏剂的能力。还观察到氨基磺酸酯衍生物对甾族硫酸酯酶和碳酸酐酶II（hCAII）的抑制活性，并通过蛋白质晶体学研究了15与hCAII之间的相互作用。在体内证实了这些多机制抗癌药的潜力，在无胸腺裸鼠MDA-MB-231人乳腺癌异种移植模型中观察到有前景的14和15活性。
