  Synthesis and evaluation of novel 4-amino-4,6-androstadiene-3,17-dione: An analog of formestane

  摘要：

  Synthesis of 4-amino-4,6-androstadiene-3,17-dione 7, an analog of formestane used in breast cancer therapy as an aromatase inhibitor, from 4-acetoxy-4-androstene-3,17-dione 2 is described. This is the first report of a 4-amino diene (4,6) system in this series of molecules. The new (7) and reported molecules were screened by the National Cancer Institute (NCI, Bethesda, USA) for in vitro antitumor activity against 60 human cancer cell lines. Molecule 7 showed best activity against breast cancer cell line (MCF-7). (c) 2008 Elsevier Ltd. All rights reserved.

  C-6α and C-7α androstanes were studied to disclose which position among them is more convenient to functionalize to reach superior aromatase inhibition. In the first series, the study of C-6 versus C-7 methyl derivatives led to the very active compound 9 with IC50 of 0.06 μM and Ki = 0.025 μM (competitive inhibition). In the second series, the study of C-6 versus C-7 allyl derivatives led to the best

  研究了C-6α和C-7α雄烷酮，以揭示其中的哪个位置更易于官能化以实现优异的芳香化酶抑制作用。在第一个系列中，对C-6和C-7甲基衍生物的研究导致了非常活泼的化合物9，IC50为0.06μM，Ki = 0.025μM（竞争性抑制）。在第二系列中，对C-6和C-7烯丙基衍生物的研究导致了这项工作中最佳的芳香化酶抑制剂13，IC50为0.055μM，Ki = 0.0225μM（不可逆抑制）。除了这些发现外，可以得出结论，C-6α位置比C-7α更好的功能化，除了同时存在一个C-4取代基时。另外，甲基是最好的取代基，其次是烯丙基，其次是羟基。为了合理化最佳抑制剂13的构效关系，
