monitoring the growth kinetics of K562 cell during a period of 72 h using the real-time live-cell imaging. Among these compounds, 1-(5-((6-((3-morpholinopropyl) amino)pyrimidin-4-yl)thio)-1,3,4-thiadiazol-2-yl)-3-(4-(trifluoromethyl)phenyl)urea (7) exhibited the least cellular toxicity and better biological activity in cellular assays (K562, IC50: 0.038 μM). Compound 7 also displayed very good induced-apoptosis
在这项研究中,通过简单而有效的结构合成了一系列1-苯基-3-(5-(嘧啶-4-基硫基)-1,3,4-噻二唑-2-基)脲受体酪氨酸激酶抑制剂基础的设计。基于细胞测定法对这些化合物的结构活性关系(SAR)分析导致发现了许多化合物,这些化合物显示出对人类慢性粒细胞白血病(CML)细胞K562的有效活性,但通过监测细胞毒性非常弱或没有细胞毒性实时活细胞成像显示K562细胞在72小时内的生长动力学。在这些化合物中,1-(5-((6-((3-吗啉代丙基)氨基)嘧啶-4-基)硫基)-1,3,4-噻二唑-2-基)-3-(4-(三氟甲基)苯基)脲(7)在细胞测定法(K562,IC50:0.038μM)中表现出最小的细胞毒性和更好的生物学活性。化合物7对人CML细胞系K562也显示出非常好的诱导凋亡作用,并通过人磷酸激酶阵列分析通过PI3K / Akt信号途径的蛋白磷酸化显着降低而发挥了其作用。体外结果表明1
