Wang, Jie;Wei, Shangfei;Li, Tong;Xing, Lingyun;Cao, Meng;Jiang, Nan;Guo, Ming;Zuo, Daiying;Zhai, Xin research published 《 Structure-based design of 2,4-diaminopyrimidine derivatives bearing a pyrrolyl group as ALK and ROS1 inhibitors》, the research content is summarized as follows. In order to develop potent ALK and ROS1 dual inhibitors, twenty-eight 2,4-diaminopyrimidine derivatives (9a-9n and 10a-10n) bearing a pyrrolyl moiety were designed and synthesized based on the co-crystal structure of ceritinib with ALKwt protein. Most compounds displayed considerable activity against ALK and ROS1 addicted cells; meanwhile, compound 10d showed excellent activity against Karpas299, H2228 and HCC78 with IC50 values of 0.01, 0.08 and 0.042μM. Subsequently, seven compounds were selected for kinase studies in vitro, resulting in the discovery of 10d with IC50 values of 1.8, 4.3 and 3.6 nM against ALK, ALKL1196M and ROS1, resp. Furthermore, the biol. assays revealed that compound 10d induced cell apoptosis in a dose-dependent manner. Ultimately, mol. docking studies presented reasonable and optimal binding interactions with ALKwt and ROS1.
Electric Literature of 103-76-4, 1-(2-Hydroxyethyl)piperazine is a useful research compound. Its molecular formula is C6H14N2O and its molecular weight is 130.19 g/mol. The purity is usually 95%.
