A series of triazole-substituted quinazoline hybrid compounds were designed and synthesized for anticancer activity targeting epidermal growth factor receptor (EGFR) tyrosine kinase. Most of the compounds showed moderate to good antiproliferative activity against four cancer cell lines (HepG2, HCT116, MCF-7, and PC-3). Compound showed good antiproliferative activity (IC = 20.71 μM) against MCF-7 cell lines. Molecular docking results showed that compound formed hydrogen bond with Met 769 and Lys 721 and π-sulfur interaction with Met 742 of EGFR tyrosine kinase (PDB ID: 1M17). Compound decreases the expression of EGFR and p-EGFR. It also induces apoptosis through reactive oxygen species generation, followed by the change in mitochondrial membrane potential.
设计并合成了一系列三唑取代的喹唑啉杂化化合物,用于靶向表皮生长因子受体(EGFR)酪氨酸激酶的抗癌活性研究。大多数化合物对四种癌细胞系(HepG2、HCT116、MCF-7和PC-3)表现出中度至良好的抗增殖活性。化合物对MCF-7细胞系表现出良好的抗增殖活性(IC = 20.71 μM)。分子对接结果表明,化合物与EGFR酪氨酸激酶的Met 769和Lys 721形成氢键,并与Met 742形成π-硫相互作用(PDB ID:1M17)。化合物降低了EGFR和p-EGFR的表达。它还通过产生活性氧诱导细胞凋亡,随后线粒体膜电位发生变化。
