With the help of the establishment of novel reaction methodology, a series of N-Aryl-5-(2,2,2-trifluoroethoxy)-1,5-dihydro-2H-pyrrol-2-one conjugates were designed and synthesized in 2–4 steps, and subsequent anticancer activity of these compounds was evaluated. Preliminary results showed that these compounds have moderate to potent activities against human acute leukemia cells K562, human lung cancer
借助新反应方法的建立,设计并合成了一系列N -Aryl-5-(2,2,2-trifluoroethoxy)-1,5-dihydro-2 H -pyrrol-2-one 偶联物。 2-4 个步骤,然后评估这些化合物的后续抗癌活性。初步结果表明,这些化合物对人急性白血病细胞 K562、人肺癌 A549、人乳腺癌 MDA-MB-231 和人宫颈癌 HeLa 癌细胞系具有中度至强效的活性。其中,化合物2d和2k对K562细胞系最有效,IC 50值分别为0.07和0.52 µM,毒性为2d对正常肝细胞(LO2)细胞系低(存活率81%)。流式细胞仪分析显示,2d有效地将 K562 细胞阻滞在 G2/M 期,甚至比 Combretastatin A4 (CA4) 好得多。此外,结果表明参与了半胱天冬酶依赖性或独立的细胞凋亡途径,这可以通过 FADD、半胱天冬酶原 3、切割半胱天冬酶 3、HTRA2/Omi、SMAC/Diablo
