tyrosine kinase family is one of the most important targets in current cancer therapy regimens. In this study, we have designed and synthesized a series of thieno[2,3-d]pyrimidine derivatives as an EGFR and HER2 tyrosine kinase inhibitors. All the synthesized compounds were evaluated in vitro for their inhibitory activities against EGFRWT; and the most active compounds that showed promising IC50 values
许多激酶的失调与癌症的发展直接相关,酪氨酸激酶家族是当前癌症治疗方案中最重要的靶标之一。在这项研究中,我们设计并合成了一系列噻吩并[2,3-d]嘧啶衍生物,作为EGFR和HER2酪氨酸激酶抑制剂。在体外评估所有合成的化合物对EGFRWT的抑制活性。并测试了对EGFRWT表现出有希望的IC50值的最具活性的化合物对突变EGFRT790M和HER2激酶的抑制活性。此外,测试了这些化合物对四种癌细胞系(HepG2,HCT-116,MCF-7和A431)的抗肿瘤活性。化合物13g,13h和13k对所检查的细胞系表现出最高活性,IC50值为7.592±0。相当于厄洛替尼的32至16.006±0.58 µM(IC50为4.99±0.09至13.914±0.36 µM)。此外,选择了最有效的抗肿瘤药(13k)进行进一步研究,以确定其对MCF-7细胞系中细胞周期进程和细胞凋亡的影响。结果表明,该化合物阻滞了细胞周期的G2
