  摘要：

  从d-葡萄糖开始，已设计并合成了三个具有d-阿拉伯立体化学和在C-2'位置（5-7）具有氮官能团的氮官能团的新的噻唑呋林类似物。已知的d-xylo立体异构体1（化合物2）以及两个在C-3'（3和4）带有氮官能团的新类似物也已由相同的糖前体合成。合成过程由以下三个阶段组成：（i）多步合成适当保护的戊呋喃糖基氰化物，（ii）通过将所得的呋喃呋喃糖基氰化物与l-半胱氨酸乙酯进行环缩合，然后再将其制得的呋喃呋喃糖基氰化物环化，来构建乙基噻唑-4-羧酸酯部分。脱氢，以及（iii）使用酯氨解将噻唑-4-甲酸乙酯最终转化为目标噻唑呋喃类似物。在基于细胞培养的测定中评估了噻唑呋林类似物的抗肿瘤活性。化合物3、4（d-xylo）和7（d-阿拉伯糖）显示出显着的抗肿瘤活性，IC50值在4-7 nM范围内。初步的结构-活性关系允许鉴定两个具有超过母体化合物1的抗增殖活性的类似物几个数量级（例如，抗Raji的比为

  Synthesis and biological evaluation of new pyrazole- and tetrazole-related C-nucleosides with modified sugar moieties

  摘要：

  3(5)-Carboxamido-4-(beta-D-ribofuranosyl)pyrazoles bearing 2'-benzamido (15) and 3'-mesyloxy (29) isosteric groups, as well as the tetrazole C-nucleosides with 2-benzamido-2-deoxy-beta-D-ribofuranose (19) and 3-azido-3-deoxy-beta-D-xylofuranose (36) as sugar segments, have been synthesized starting from D-glucose, by utilizing the 2,5-anhydro-D-glucose ethylene acetal derivatives 1 and 20 as divergent intermediates. The C-nucleosides 15 and 36 were shown to be moderate inhibitors of the in vitro growth of both N2a and BHK 21 tumour cell lines, whereas 29 showed a selective, although not potent cytotoxic activity against N2a cells. Compound 29 also showed a moderate in vitro antiviral activity towards the rabies virus. (C) 2002 Elsevier Science Ltd. All rights reserved.

  A divergent synthesis of two novel tiazofurin analogues, 2-(3-deoxy-3-fluoro-beta-D-xylofuranosyl)thiazole-4-carboxamide (2) and 2-(3-acetamido-3-deoxy-beta-D-xylofuranosyl)thiazole-4-carboxamide (3), has been achieved starting from D-glucose. Both nucleoside analogues were evaluated for their in vitro cytotoxicity against several human leukaemia and solid tumour cell lines.

  A new tiazofurin analogue, 2-(3-amino-3-deoxy-p-D-xylofuranosyl)thiazole-4-carboxamide (3), was synthesized starting from D-glucose and evaluated for its in vitro antiproliferative activity against a panel of human tumour cell lines. Compound 3 exhibited the most powerful cytotoxicity against K562 cells, being approximately 100-fold more potent than tiazofurin. This analogue was also active against Jurkat, HT-29 and HeLa malignant cells, with respective IC50 values being ca. 2-, 27- and 17-fold lower than those observed for tiazofurin. Remarkably, compound 3 did not exhibit any significant cytotoxicity towards normal foetal lung MRC-5 cell line. (c) 2006 Elsevier Ltd. All rights reserved.
