indicate that compound 19m has a good drug safety. Partial ADME properties were evaluated in vitro and in vivo. Compound 19m exhibited a good AUC values and volume of distribution and low clearance in the pharmacokinetics experiment of rats. Finally, a pharmacophore model guided by experimental results is proposed. We hope this theoretical model can help researchers find type I TRK inhibitors more efficiently
原肌球蛋白受体激酶 TRK 负责由NTRK基因融合引起的不同肿瘤类型,并已被确定为抗癌治疗的成功靶点。在此,我们通过合理的药物设计策略,从微摩尔效力的17a中报道了一种有效的选择性 TRKs 抑制剂19m 。化合物19m显着抑制TRK依赖性细胞系(Km-12)的增殖,而对TRK非依赖性细胞系(A549和THLE-2)没有抑制作用。此外,激酶选择性分析表明,除了TRK之外,化合物19m仅对ALK表现出较强的抑制活性。这些数据可能表明化合物19m具有良好的用药安全性。部分 ADME 特性在体外和体内进行了评估。化合物19m在大鼠药代动力学实验中表现出良好的AUC值和分布容积以及较低的清除率。最后,提出了以实验结果为指导的药效团模型。我们希望这个理论模型能够帮助研究人员更有效地寻找I型TRK抑制剂。
