first-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), gefitinib and erlotinib significantly improved the therapeutic effect in non–small cell lung cancer (NSCLC) patients with EGFR mutation. However, the EGFRT790M mutation occurs and results in acquired resistance. Consequently, mutant selective third-generation EGFR TKIs represented by AZD9291 (Osimertinib) have been
第一代表皮生长因子受体(EGFR)酪氨酸激酶抑制剂(TKI)吉非替尼和厄洛替尼显着提高了EGFR突变非小细胞肺癌(NSCLC)患者的治疗效果。然而,EGFR T790M突变发生并导致获得性耐药。因此,以AZD9291(奥希替尼)为代表的突变选择性第三代EGFR TKI被开发出来,以提供更有效的治疗,但临床应用受到获得性耐药和高昂成本的限制。合成了一系列5-氯嘧啶-2,4-二胺衍生物,并筛选了其对H1975和A431细胞的体外抗肿瘤活性。 XHL11显示出最强的抗肿瘤活性。与 AZD9291 相比,XHL11 抑制具有 EGFR L858R/T790M突变的 H1975 细胞的细胞增殖和集落形成并诱导细胞凋亡。此外,XHL11引起EGFR和凋亡相关通路的表达变化。此外,在 H1975 皮下异种移植模型中,口服 XHL11 可抑制体内肿瘤进展。这些数据表明,XHL11 可能被开发为一种有前途的
