the National Cancer Institute-United States of America (NCI-USA) anticancer screening program. Compound 5 (7-Chloro-3-(2,4-dimethoxyphenyl)-5-methylthiazolo[4,5-d]pyrimidine-2(3H)-thione) was found to have a potent and broad-spectrum cytotoxic action against NCI panel with GI50 (50% growth inhibition concentration) mean graph midpoint (MG-MID) = 2.88 µM. MTT assay was used to determine IC50 values of
合成了新的噻唑并[4,5- d ]嘧啶类似物,并对它们的抗肿瘤活性进行了体外生物学评估。通过美国国家癌症研究所(NCI-USA)的抗癌筛选计划评估了这些化合物的生长抑制作用。发现化合物 5 (7-氯-3-(2,4-二甲氧基苯基)-5-甲基噻唑并[4,5- d ]嘧啶-2(3 H)-硫酮)具有有效的广谱细胞毒作用具有GI 50(50%生长抑制浓度)的NCI面板平均图中点(MG-MID)= 2.88 µM。使用MTT测定法测定IC 50最有效的抗HCT-116大肠癌和WI-38人肺成纤维细胞系药物的价值;分别为5.33 µM±0.69和21.69 µM±1.04。流式细胞仪分析表明化合物 5 触发凋亡和G2 / M细胞周期停滞。评价化合物 5 抑制CDK1(细胞周期蛋白依赖性激酶1)/细胞周期蛋白B复合物的能力,其IC 50值为97nM±2.33。此外,根据基因表达分析,化合物 5除了下调B
