摘要

(5R)-Cleistenolide和一些相关的类似物已经从d-葡萄糖开始合成。合成的关键步骤包括z选择性Wittig烯化和分子内C-5位构型反转的Mitsunobu反应。合成化合物的体外抗增殖活性在8个人类肿瘤细胞组和单个正常细胞系(MRC-5)上进行了测试。大多数被测试的化合物对某些人类肿瘤细胞有很强的抗增殖作用,对正常胎儿肺成纤维细胞(MRC-5)的毒性均可忽略不计。本研究获得的活性最高的化合物是内酯5,其在MDA-MB 231细胞培养中与阿霉素具有相同的活性(IC50为0.09 μ M)。类似物2、5和6在K562细胞株中具有较强的抗增殖活性(IC50分别为0.21、0.34和0.33 μ M),与阿霉素的IC50非常接近(IC50为0.25 μ M)。一项进行的SAR研究表明,在C-5位置的立体化学变化可能会增加所产生的立体异构体的活性。

Synthesis and antiproliferative activity of (5R)-cleistenolide and analogues
(5R)-Cleistenolide and a few related analogues have been synthesized starting from d-glucose. The key steps of the synthesis included a Z-selective Wittig olefination and an intramolecular Mitsunobu reaction with an inversion of configuration at the C-5 position. In vitro antiproliferative activity of synthesized compounds was tested on a panel of eight human tumour cells and against a single normal cell line (MRC-5). The majority of tested compounds showed strong antiproliferative effects on certain human tumour cells and all of them showed negligible toxicity to normal foetal lung fibroblasts (MRC-5). The most active compound obtained in this work is lactone 5, which in MDA-MB 231 cell culture showed the same activity as doxorubicin (IC50 0.09 ?M). Strong antiproliferative activities of analogues 2, 5 and 6 were recorded in the K562 cell line (IC50 0.21, 0.34 and 0.33 ?M, respectively), in which they showed very similar activities to doxorubicin (IC50 0.25 ?M). A performed SAR study revealed that a change in the stereochemistry at the C-5 position may increase the activity of resulting stereoisomers.
