Abstract In this paper, a set of 3-methylquniazolinone derivatives were designed, synthesised, and studied the preliminary structure-activity relationship for antiproliferative activities. All target compounds performed significantly inhibitory effects against wild type epidermal growth factor receptor tyrosine kinase (EGFRwt-TK) and tumour cells (A431, A549, MCF-7, and NCI-H1975). In particular, compound
抽象的 本文设计、合成了一组3-甲基喹唑啉酮衍生物,并研究了其抗增殖活性的初步构效关系。所有目标化合物对野生型表皮生长因子受体酪氨酸激酶(EGFR wt -TK)和肿瘤细胞(A431、A549、MCF-7和NCI-H1975)均表现出显着的抑制作用。特别是,化合物4d 3-氟-N- (4-((3-甲基-4-氧代-3,4-二氢喹唑啉-2-基)甲氧基)苯基)苯甲酰胺对所有肿瘤细胞均表现出比吉非替尼更高的抗增殖活性。 IC 50分别为 3.48、2.55、0.87 和 6.42 μM)。此外,化合物4d在测试浓度下可诱导MCF-7细胞凋亡并停滞在G2/M期。分子对接和ADMET研究表明,化合物4d可以与EGFR wt -TK紧密形成多个氢键。因此,化合物4d有潜力开发为新型抗癌药物。
