New series of compounds bearing 2-thioquinazolinone scaffold were designed, synthesized as HSP90 inhibitors. Anti-proliferative activity of the synthesized compounds was evaluated against HCT-116, Hela and MCF-7 cell lines and compound 5k was found to be the most active member of the entire study with IC50 of 4.47, 7.55 and 4.04 μM, respectively, compared to DOX (IC50 of 5.23, 5.57 and 4.17 μM, respectively)
设计了带有2-硫代喹唑啉酮骨架的新系列化合物,将其合成为HSP90抑制剂。评估了合成化合物对HCT-116,Hela和MCF-7细胞系的抗增殖活性,发现化合物5k是整个研究中最活跃的成员,IC 50分别为4.47、7.55和4.04μM,与DOX相比(IC 50分别为5.23、5.57和4.17μM)。大多数测试化合物显示出对正常成纤维细胞WI-38较低的细胞毒性。化合物5b,5k和8a显示出有效的HSP90抑制活性,IC 50值在纳摩尔范围内。抗坦西霉素(IC,分别为71.32、25.07和56.78 nm50 of 86.45 nm)。通过下调HSP90客户蛋白Her2和上调伴侣HSP70水平,证实了它们对HSP90的抑制活性。化合物5k对EGFR,VEGFR-2和拓扑异构酶-2表现出有效的多靶点抑制活性,IC 50值在纳摩尔范围内。38.5、126.95和25.85 nm。使用流式细
