中文摘要：

合成了系列新的3-芳基噻唑烷-4-酮-2-酰胺衍生物, 并测试了化合物抑制肿瘤细胞增殖活性. 部分化合物对A-549和Hela肿瘤细胞有弱的细胞毒性, 而对BGC-823没有抑制作用, 表现出一定的选择性. 其中, 化合物7ad对A-549有较强的抑制活性（IC50＝21.0 μmol？L－1）, 与阳性对照顺铂的抑制活性（IC50＝19.4 μmol？L－1）相当. 初步的构效关系表明化合物的立体结构可能对其抗肿瘤活性影响较大.

英文摘要：

A series of novel 3-aryl-4-oxo-thiazolidin-2-carboxylic acid amides were synthesized and evalu- ated for their antiproliferative activity for three tumor cells. Some compounds showed weak cytotoxicity against A-549 and Hela tumor cells, but no antiproliferative activity against BGC-823, which suggested such compounds with a certain cytotoxicity selectivity to the three tumor cells. Among them, compound 7ad was the best one against A-549 with the IC50 value of 21.0 μmol.L-1, nearly equivalent to that of the positive control cisplatin （IC50=19.4 μmol.L-1）. Preliminary structure activity relationship analysis of these ana- logues suggested that the steric factor may be important to the anti-tumor activity.
