  Antiproliferation and apoptosis induced by C-glycosides in human leukemia cancer cells

  摘要：

  A large series of alkyl C-glycosides was synthesized from D-glucal or D-galactal. These compounds were screened against the human promyelocytic leukemia cell line (HL60), showing significant activity and apoptosis. Up to 13 C-glucopyranosides, but no C-galacto- or C-mannopyranosides, exhibited inhibitory concentrations (IC50 values) below 20 mu M, five of them in the range 4-8 mu M. Preliminary structure-activity relationships were established. (c) 2006 Elsevier Ltd. All rights reserved.

  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.

  A series of alkyl α-d-C-glucopyranosides were synthesized and their conformational properties analyzed by CD and NMR spectroscopy. The conformational analysis revealed that the hydroxymethyl group populations (torsion angle ω, O1–C1–C2–O2) and those around the C-glucopyranosidic bond (torsion angle Φ; O2–C6–C7–C8) depend on the structural nature of the C-aglycon. The gt and the exo–syn populations

  合成了一系列烷基α-d- C-吡喃葡萄糖苷，并通过CD和NMR光谱分析了它们的构象性质。构象分析表明，羟甲基基团（扭转角ω，O1-C1-C2-O2）和C-吡喃葡萄糖苷键周围的分子（扭转角Φ； O2-C6-C7-C8）取决于分子的结构性质。C-糖苷配基。在GT和外-顺式种群增加作为Ç -aglycon变得更加取代。这些旋转种群和质子化学位移与塔夫脱的空间参数之间的线性相关性揭示了碳的重要作用C-葡糖苷的整体构象中的β-糖苷配基。随着运动的空间位阻的增加，影响羟甲基旋转的立体电子外-脱氧异头作用变得更加重要。甲伪还进行端基异构体的旋转比较研究。
