  First synthesis of 3,16,20-polyoxygenated cholestanes, new cytotoxic steroids from the gorgonian Leptogorgia sarmentosa

  摘要：

  Using tigogenin as starting material, (20S)-20-hydroxycholestane-3,6-dione (1), (16S, 20S)-16,20-dihydroxycholestan-3-one (2), (20S)-20-hydroxycholest-1-ene-3,16-dione (3) and (20S)-20-hydroxycholest-4-ene-3,16-dione (4), natural polyoxygenated Steroids from the gorgonian, Leptogorgia sarmentosa, were synthesized in four steps. Antitumor activity against three tumor cell lines (breast cancer, MCF7, lung cancer NCI and oral cancer KB) was evaluated. Two compounds (3 and 4) showed strong activity against NCI (IC50 6.16 and 10.51 mu M) and moderate activity against MCF7 and KB, the IC50 being in the range 30.6S-47.22 mu M. Compound 2 showed moderate activity against NCI (IC50 42.68 mu M) but was inactive against MCF7 and KB whereas compound 1 showed no activity against all tested cells. (c) 2008 Elsevier Inc.

  A series of new polyoxygenated steroid derivatives with various steroid skeleton moieties were synthesized. Antitumor activity of the compounds against three tumor cell lines (Breast cancer MCF7, lung cancer NCl and oral cancer KB) were evaluated. Compounds with aromatic A ring of this series exhibited the most potent cytotoxicities in all tested cells. The absence of OH at C-16 or lack of cholesterol like side chain at C-20 in the steroid skeleton apparently result in decreased cytotoxicity. The compound became inactive when the side chain contains double bond at C-24-C-25. When hydroxyl group at C-3 was protected no cytotoxicities against MCF7 and NCl and considerable low cytotoxicity against KB cell lines were observed. (C) 2010 Elsevier Inc. All rights reserved.
