  Synthesis and evaluation of geldanamycin-estradiol hybrids

  摘要：

  Geldanamycin (GDM) binds to the Hsp90 chaperone protein and causes the degradation of several important signalling proteins. A series of novel estradiol-geldanamycin hybrids has been synthesized and evaluated for their ability to induce the selective degradation of the estrogen receptor (ER). The hybrid compounds are active and more selective than the parent causing degradation of ER and HER2, but not other GDM targets. (C) 1999 Elsevier Science Ltd. All rights reserved.

  Abstract We report the 13 C NMR data for 17β-estradiol, 17α-estradiol, and a series of ten 17β- or 17α-estradiol derivatives bearing an allyl group on the D-ring (at C-17, C-16, and C-15 positions). The target 17β-OH estradiol derivatives were synthesized from estrone by well known methods to ensure the accuracy of the allyl stereochemistry. The 17α-estradiol derivatives were obtained by a modified

  摘要 我们报告了 17β-雌二醇、17α-雌二醇和一系列 10 种 17β- 或 17α-雌二醇衍生物的 13 C NMR 数据，这些衍生物在 D 环上带有烯丙基（在 C-17、C-16 和 C -15 个位置）。目标 17β-OH 雌二醇衍生物是通过众所周知的方法从雌酮合成的，以确保烯丙基立体化学的准确性。17α-雌二醇衍生物是通过对 17β-类似物进行改良的 Mitsunobu 醇转化获得的。碳分配是使用 1D 和 2D NMR 实验完成的。研究了 D 环的烯丙基的六个位置（17α、17β、16α、16β、15α 和 15β）和两种醇立体化学（17β 和 17α），从而获得了重要的数据来源。还确定了烯丙基定位和醇立体化学对 13 C NMR 化学位移的影响，

  The synthesis of a 16 alpha-(bromoalkylamide) derivative of estradiol (N-butyl, N-methyl, 11-[3',17'beta-(dihydroxy)-1',3',5'(10')-estratrien-16'alpha-yl]-9(R/S)-bromo undecanamide) was performed by two different approaches starting from estrone. Each approach hers the same key intermediate, containing an aldehyde group, but differs by the bromination step and the timing of formation of the amide group. This compound was found to cause, at 100 mu M, a complete inhibition of 17 beta-hydroxysteroid dehydrogenase (17 beta-HSD) responsible for the interconversion of estrone and estradiol. The corresponding IC50 value was 10.6 mu M. In the estrogen-sensitive ZR-75-1 human breast cancer cell line, this estradiol derivative has no estrogenic activity at 30 nM and only a minimal estrogenic activity (10% above the basal level) at 1 mu M. At this latter concentration, this compound causes a 28% inhibition of 0.1 nM EI-induced cel[proliferation (antiestrogenic activity). Thus, the introduction of a side-chain with a secondary bromide and a butyl methyl amide group at the 16 alpha-position of estradiol has two interesting effects; namely an inhibition of cytosolic 17 beta-HSD and a blockade of the estrogenic effect of estradiol.
