Novel 2-arylmethoxy-4-(2,2′-dihalogen-substituted biphenyl-3-ylmethoxy) benzylamine derivatives were designed, synthesized, and evaluated in vitro and in vivo against cancers as PD-1/PD-L1 inhibitors. Through the computer-aided structural optimization and the homogeneous time-resolved fluorescence (HTRF) assay, compound A56 was found to most strongly block the PD-1/PD-L1 interaction with an IC50 value
设计、合成了新型 2-芳基甲氧基-4-(2,2'-二卤素取代的联苯-3-基甲氧基)苄胺衍生物,并在体外和体内评估了其作为 PD- 1 / PD -L1 抑制剂的抗癌作用。通过计算机辅助结构优化和均相时间分辨荧光(HTRF)测定,发现化合物A56能够最强地阻断 PD-1/PD-L1 相互作用,IC 50值为 2.4 ± 0.8 nM,并显示出最强的阻断PD-1/PD-L1 相互作用的能力。有效的活动。1 H NMR滴定结果表明A56可以与PD-L1蛋白紧密结合,K D < 1 μM。A56/ PD-L1 复合物 (3.5 Å)共晶结构的 X 射线衍射数据详细破译了一种新的结合模式,这可以解释其最有效的抑制活性。基于细胞的检测进一步证明了A56作为 hPD-1/hPD-L1 阻断剂的强大能力。尤其是在hPD-L1 MC38人源化小鼠模型中,A56显着抑制肿瘤生长,且无明显毒性,TGI率为55.20%(50
