remarkably inhibit the proliferation of the B lymphoma cell lines at concentrations of 6.49 μM (Ramos cells) and 13.2 μM (Raji cells), and was stronger than the novel agent spebrutinib. In addition, the inhibitory potency toward the normal PBMC cells showed that inhibitor 10c possesses low cell cytotoxicity. All these explorations indicated that molecule 10c could serve as a valuable inhibitor for B-cell
通过将功能性磺酰胺引入嘧啶模板的C-2苯胺部分,合成了一系列新的二苯基嘧啶衍生物(SFA-DPPYs),然后对其进行生物学评估,认为其是有效的Bruton酪氨酸激酶(BTK)抑制剂。在这些分子中,抑制剂10c,10i,10j和10k对BTK酶显示出高效力,IC50值分别为1.18 nM,0.92 nM,0.42 nM和1.05 nM。特别地,化合物10c可以在6.49μM(Ramos细胞)和13.2μM(Raji细胞)的浓度下显着抑制B淋巴瘤细胞系的增殖,并且比新药斯培鲁替尼更强。另外,对正常PBMC细胞的抑制能力表明抑制剂10c具有低细胞毒性。
