In this paper some semicarbazide and 1,2,4-triazolin-5-one derivatives are evaluated in vitro for their anticancer
activity towards human tumour cell line: ovary (TOV 112D), lung (A 549), breast (T47D) and uterus (Hela). Compounds
2-4 have been found to show the most effective in vitro activity against ovary cancer cell line. For compound 4 the growth
inhibition (80% and 70%) is observed in two concentrations (100 μg/ml and 50 μg/ml). The cytotoxic effect of examined
compounds seems to be dose-dependent and time-dependent. Compound 7 has GI=80% values towards the breast cancer
cell line in concentration of 100 μg/ml. Structure-activity relationship (SAR) studies are carried out for all the compounds
of the series. Compounds 2-4 show an activity profile that can be improved through medicinal chemistry strategies.

生物对人类肿瘤细胞株(卵巢(TOV 112D)、肺(A 549)、乳腺(T47D)和子宫(Hela))的体外抗癌活性。研究发现,化合物 2-4 对卵巢癌细胞株具有最有效的体外活性。在两种浓度(100 微克/毫升和 50 微克/毫升)下,化合物 4 的生长抑制率分别为 80% 和 70%。所研究化合物的细胞毒性作用似乎是剂量依赖性和时间依赖性的。浓度为 100 μg/ml 的化合物 7 对乳腺癌细胞株的 GI 值为 80%。对该系列的所有化合物都进行了结构-活性关系(
SAR)研究。化合物 2-4 显示出了可通过药物
化学策略加以改进的活性特征。
