  Cytotoxic effects of C-glycosides in HOS and HeLa cell lines

  摘要：

  Fifty-two C-glycosides were synthesized and their in-vitro antiproliferative activity screened against human cervical carcinoma (HeLa) and osteosarcoma (HOS) cell lines. Nine of them had growth inhibitions (GI(50) values) below 10 mu M, the Gglucopyranoside 38 being the most active against HeLa (5.4 mu M) and the dichlorocyclopropyl derivative 42 against HOS (1.6 mu M). Some preliminary structure-activity relationships were established. (c) 2007 Elsevier Ltd. All rights reserved.

  α-C-Glycosides have been prepared by the addition of organozinc reagents to glycal epoxides. Dialkyl and diaryl zinc reagents in the presence of CF3COOH provide the corresponding α-glycosides in 53-82% yields. Organozinc chlorides RZnCl formed by the reaction RLi with zinc chloride can also be successfully applied to this coupling reaction with high α-selectivity.

  α-C-糖苷是通过将有机锌试剂加入糖醇环氧化物制备的。在CF3COOH的存在下，二烷基和二芳基锌试剂能以53-82%的产率提供相应的α-糖苷。由RLi与氯化锌反应形成的有机锌氯化物RZnCl也可以成功应用于这种偶联反应，并具有很高的α-选择性。
