Methyl Xestospongoate类似物的设计、合成和抗肿瘤活性

Studies on methyl xestopongoate analogues:design, synthesis and antitumor activities

摘要: 设计、合成了52个Methyl Xestospongoate类似物并初步研究了其抗肿瘤活性。以炔基甲酯和二炔为原料，经过Cadiot-Chodkiewitz偶联和Sonogashira偶联反应合成了52个Methyl Xestospongoate类似物 4(a~m) - 7( a ~ m )，并利用¹H NMR、¹³C NMR和HREI-MS法确定其结构，采用CCK-8法测定了部分化合物的体外抗肿瘤活性。结果显示化合物 6k 对A549和P-388肿瘤细胞的增殖具有较强的抑制活性，其IC₅₀分别为9.36和9.62 μmol/L。

Abstract: Fifty-two methyl xestospongoate analogues were designed, synthesized and evaluated for the antiproliferative activity. Starting from alkynyl methyl ester and diyne, methyl xestospongoate analogues 4 ( a - m )- 7( a - m )were synthesized by Cadiot-Chodkiewitz coupling and Sonogashira coupling reactions. Their structures were identified by ¹H NMR, ¹³C NMR and HREI-MS. The cytotoxic inhibiton activities in vitro of some compounds were evaluated against human cancer cells A549 and P-388 by a CCK-8 method. Among them, compound 6k exhibited potent cell growth inhibitory activity against A549 and P-388 cancer cells, with IC₅₀ values of 9. 36 and 9. 62 μmol/L, respectively.
