以胺、异硫氰酸酯和炔酯为原料, 通过三组分偶联环化制备了一系列4-氧代-2-亚胺基噻唑烷-5-亚基乙酸乙酯类化合物. 采用噻唑蓝(MTT)法研究了目标化合物对人肝癌细胞HepG2和人乳腺癌细胞MCF-7的体外抗癌活性, 结果发现大多数化合物显示出明显的抗癌活性. 与顺铂相比, (Z)-2-((Z)-2-((3,4-二氯苯基)亚氨基)-3-(3-(4-甲基哌嗪-1-基)丙基)-4-氧代噻唑烷-5-亚基)乙酸乙酯(4r)表现出最好的细胞毒性, 对HepG2和MCF-7的IC50值分别为0.88和0.80 μmol/L, 并且讨论了药物的初步构效关系. 这些化合物对肿瘤细胞具有良好的生物活性, 是一类有应用前景的化学治疗药物, 值得进行后续研究.

A series of novel ethyl 4-oxo-2-iminothiazolidin-5-ylidene acetate derivatives were synthesized through the three- component coupling annulation of amines, isothiocyanates and diethyl but-2-ynedioates. The obtained compounds were assayed in vitro for their anti-cancer activities against human liver cancer (HepG2) and human breast cancer (MCF-7) cell lines by standard methyl thiazolyl tetrazolium (MTT) method, most of which exhibited significant cytotoxicity. In particular, ethyl (Z)-2-((Z)-2-((3,4-dichlorophenyl)imino)-3-(3-(4-methylpiperazin-1-yl)propyl)-4-oxothiazolidin-5-ylidene)-acetate (4r) displayed the highest level of cytotoxicity compared with cisplatin, and its IC50 values for HepG2 and MCF-7 cells were 0.88 and 0.80 μmol/L, respectively. Their preliminary structure-activity relationship was also discussed. The remarkable cytotoxic nature of these substances against cancer cells could be considered as promising chemotherapeutic agents to be developed in future.

Key words: ethyl 4-oxo-2-iminothiazolidin-5-ylidene acetate, anti-cancer activity, structure-based drug design, structure- activity relationship
