Tropomyosin receptor kinase (TRK) is a successful target for the treatment of various cancers caused by NTRK gene fusions. Herein, based on a rational drug design strategy, we designed and synthesized 35 aminopyrimidine derivatives that were shown to be TRKA inhibitors in the enzyme assay, among which compounds C3, C4, and C6 showed potent inhibitory activities against TRKA with IC50 values of 6.5
原肌球蛋白受体激酶 (TRK) 是治疗由NTRK基因融合引起的各种癌症的成功靶标。在此,基于合理的药物设计策略,我们设计并合成了35个氨基嘧啶衍生物,这些衍生物在酶学测定中被证明是TRKA抑制剂,其中化合物C3、C4和C6对TRKA表现出有效的抑制活性, IC 50值为6.5。 、5.0 和 7.0 nM,分别。体外抗增殖活性研究表明,化合物C3显着抑制KM-12细胞的增殖,但对MCF-7细胞和HUVEC细胞的抑制作用较弱。成药性初步评价表明,化合物C3表现出良好的肝微粒体和血浆稳定性,并且在 10 µM 时对细胞色素 P450 亚型具有弱或无抑制活性。还选择化合物C3、C4和 C6进行 ADME(吸收、分布、代谢和消除)特性预测和分子对接研究。抑制实验表明化合物C3对 TRK 亚型没有选择性。所有结果表明,化合物C3是开发 TRK 抑制剂的有用候选物。
