By merging the critical pharmacophore of EGFR/HER2 and HDAC inhibitors into one compound, a novel series of EGFR, HER-2, and HDAC multitarget inhibitors were synthesized. Compounds 9a-l contained 4-anilinoquinazolines with C-6 triazole-linked long alkyl chains of hydroxamic acid and displayed excellent inhibition against these enzymes (compound 9d exhibited the best inhibitory potency on wild-type
通过将
EGFR / HER2和H
DAC抑制剂的关键药效团合并为一个化合物,合成了一系列新的
EGFR,HER-2和H
DAC多靶点
抑制剂。化合物9a-1含有4-
苯胺基
喹唑啉和C-6三唑连接的异羟
肟酸长烷基链,对这些酶表现出优异的抑制作用(化合物9d对野生型
EGFR,H
DAC1和H
DAC6表现出最佳的抑制效能,IC50值分别为0.12 nM,0.72nM和3.2nM)。此外,化合物9b和9d有效抑制了五种人类癌
细胞系的增殖(IC50值在0.49至8.76μM之间)。进一步的机理研究表明,化合物9d在细胞
水平上还调节
EGFR和HER2的
磷酸化以及组蛋白H3的超乙酰化,并诱导BT-474细胞显着的凋亡。所以,
