The synthesis and antitumor activity screening of 4-aminothiazol-2(5H)-one derivatives
were performed. The absence of possible 4-amino-imino tautomerism of thiazolidinones-2 has been
confirmed based on the study of the molecule structures. The existence of the alone amino-form was
confirmed. An anticancer activity screening was performed within the Developmental Therapeutics Program (National
Cancer Institute/NIH, USA). Tested compounds possess low to moderate anticancer activity (average values - 60 cancer
cell lines assay) with significant selective action on certain cancer cell lines (CCRF-CEM and RPMI-8226/leukemia,
U251/CNS cancer, RFX 393/renal cancer, OVCAR/ovarian cancer etc.). The advantage of 5-ylidene-4-R-amino derivatives
in comparison with compounds with free amino group was shown. Some structure-activity findings, the comparison
of target compounds with isomeric 5-ylidene-2-imino(amino)thiazol-4(5H)-ones, as well as COMPARE analysis were described.
Among the tested compounds (Z)-5-(furan-2-ylmethylidene)-4-(4-chlorophenylamino)thiazol-2(5H)-one (IIIk)
and (Z)-5-(4-diethylaminophenylmethylidene)-4-(4-hydroxy-5-isopropyl-2-methylphenylamino)thiazol-2(5H)-one (IIIp)
possessed the highest levels of activity.
对4-氨基噻唑-2(5H)-酮衍生物的合成及抗肿瘤活性筛选进行了研究。基于对分子结构的研究,确认了噻唑啉酮-2中不存在可能的4-氨基-亚氨基互变异构体,确认了独立氨基型的存在。在国家癌症研究所/国家卫生研究院(美国)的开发疗法项目中进行了抗癌活性筛选。测试的化合物具有低到中等的抗癌活性(平均值 - 60个癌细胞系检测),对某些癌细胞系(如CCRF-CEM和RPMI-8226/白血病、U251/CNS癌、RFX 393/肾癌、OVCAR/卵巢癌等)表现出显著的选择性作用。相比于自由氨基团的化合物,5-烯基-4-R-氨基衍生物的优势得到了证明。文中还描述了一些结构-活性发现、目标化合物与异构体5-烯基-2-亚氨基(氨基)噻唑-4(5H)-酮的比较,以及COMPARE分析。在测试的化合物中,(Z)-5-(呋喃-2-基甲烯)-4-(4-氯苯基氨基)噻唑-2(5H)-酮 (IIIk) 和 (Z)-5-(4-二乙氨基苯基甲烯)-4-(4-羟基-5-异丙基-2-甲基苯基氨基)噻唑-2(5H)-酮 (IIIp) 展现了最高的活性水平。
