inhibitory activity against MDA-MB-468 cells. Moreover, analogs (3a–b and 3d–e) bearing a benzyl group at the N-2 position showed more potent activity than gefitinib, as a potent EFGR-TK inhibitor. Especially, compound 3a exhibited selective cytotoxic activity against MDA-MB-468 cells; it also had a synergistic effect in combination with gefitinib against MDA-MB-468 cells. In addition, we confirmed that compounds
设计并合成了一系列新颖的1-氧代-1,2,3,4-四氢吡嗪并[1,2- a ]吲哚-3-羧酰胺类似物,用于开发吡嗪并吲哚酮骨架作为抗乳腺癌药物。与具有脂肪族基团的化合物相比,分别具有呋喃-2-基-甲基酰胺基团和苄基酰胺基团的化合物1h和1i在MDA-MB-468三阴性乳腺癌(TNBC)细胞中表现出更强的细胞毒性。作为1h和1i的(R)-对映异构体的化合物2a和2b也具有对MDA-MB-468细胞的抑制活性。此外,类似物(3a – b和3d –e)在N -2位置带有苄基显示出比吉非替尼(作为有效的EFGR-TK抑制剂)更强的活性。尤其是,化合物3a对MDA-MB-468细胞表现出选择性的细胞毒性活性。它与吉非替尼联合使用对MDA-MB-468细胞也有协同作用。另外,使用蛋白质印迹分析,我们证实了化合物3a和3d抑制了MDA-MB-468细胞中Akt的磷酸化。因此,这些1-氧代-1,2,3,4-四氢吡嗪并[1
