  2-Substituted Estradiol Bis-sulfamates, Multitargeted Antitumor Agents:  Synthesis, In Vitro SAR, Protein Crystallography, and In Vivo Activity

  摘要：

  The anticancer activities and SARs of estradiol-17-O-sulfamates and estradiol 3,17-O,O-bis-sulfamates (E2bisMATEs) as steroid sulfatase (STS) inhibitors and antiproliferative agents are discussed. Estradiol 3,17-O,O-bis-sulfamates 20 and 21, in contrast to the 17-O-monosulfamate 11, proved to be excellent STS inhibitors. 2-Substituted E2bisMATEs 21 and 23 additionally exhibited potent antiproliferative activity with mean graph midpoint values of 18-87 nM in the NCI 60-cell-line panel. 21 Exhibited antiangiogenic in vitro and in vivo activity in an early-stage Lewis lung model, and 23 dosed p.o. caused marked growth inhibition in a nude mouse xenograft tumor model. Modeling studies suggest that the E2bisMATEs and 2-MeOE2 share a common mode of binding to tubulin, though COMPARE analysis of activity profiles was negative. 21 was cocrystallized with carbonic anhydrase II, and X-ray crystallography revealed unexpected coordination of the 17-O-sulfamate of 21 to the active site zinc and a probable additional lower affinity binding site. 2-Substituted E2bisMATEs are attractive candidates for further development as multitargeted anticancer agents.

  The present invention relates to novel substituted steroid derivatives which represent selectiv inhibitors of the 17β-hydroxysteroid dehydrogenase type I (17β-HSD1) and, in addition, which may represent inhibitors of the steroid sulphatase, as well as to their salts, to pharmaceutical preparations containing these compounds and to processes for the preparation of these compounds. Furthermore, the invention concerns the therapeutic use of said novel substituted steroid derivatives, particularly their use in the treatment, inhibition, prophylaxis or prevention of steroid hormone dependent diseases or disorders, such as steroid hormone dependent diseases or disorders requiring the inhibition of 17β-hydroxysteroid dehydrogenase type I and/or steroid sulphatase enzymes and/or requiring the lowering of the endogenous 17β-estradiol concentration.

  The synthesis and antiproliferative activity of analogues of estradiol 3,17-O,O-bis-sulfamates (E2bisMATEs) are discussed. Modifications of the C-17 substituent reveal that an H-bond acceptor is essential for high antiproliferative activity. The local environment in which this H-bond acceptor lies can be varied to an extent. The C-17-oxygen linker can be deleted or substituted with an electronically

  讨论了雌二醇3，17- O，O-双-氨基磺酸酯（E2bisMATEs）类似物的合成和抗增殖活性。C-17取代基的修饰表明，H键受体对于高抗增殖活性至关重要。该H键受体所处的局部环境可以在一定程度上变化。C-17-氧连接基可以被缺失或被电子中性的亚甲基取代，并且末端NH 2被甲基取代也是可接受的。甲磺酸酯10和14被证明与E2bisMATE 2和3等价，而砜20和35显示出增强的体外抗增殖活性。另外，首次建立了2-取代的雌二醇-3 - O-氨基磺酸衍生物作为微管蛋白聚合抑制剂的SAR 。这些试剂抑制放射性标记的秋水仙碱与微管蛋白的结合。
