Targeting acquired drug resistance is the major challenge in the treatment of EGFR-driven non-small cell lung cancer (NSCLC). In this study, a novel class of compounds containing pyrido[3,4-d]pyrimidine scaffold was designed as new generation EGFR-TKIs to overcome this challenge. The most promising compound B30 inhibited HCC827 and H1975 cells growth with the IC50 values of 0.044 μM and 0.40 μM, respectively
靶向获得性耐药是治疗EGFR驱动的非小细胞肺癌(NSCLC)的主要挑战。在这项研究中,一类新型的含有吡啶并[3,4- d ]嘧啶骨架的化合物被设计为新一代的EGFR-TKI,以克服这一挑战。最有希望的化合物B30抑制HCC827和H1975细胞生长,IC 50值分别为0.044μM和0.40μM 。同时,B30表现出对EGFR L858R(IC 50 = 1.1 nM)和EGFR L858R / T790M / C797S(IC 50 = 7.2 nM)的有效抑制活性。B30可以剂量依赖的方式抑制HCC827细胞中EGFR的磷酸化,并显着诱导HCC827细胞凋亡。分子对接表明B30中的羟基可以与突变体Ser797形成额外的氢键。这些发现强烈支持我们的假设,即2,4,6-三取代的吡啶并[3,4- d ]嘧啶衍生物可以用作EGFR-TKI。由小分子抑制剂与突变体Ser797形成的预测氢键相
