Hybridization strategy is an effective strategy to obtain multi-target inhibitors in drug design. In this study, we assembled the pharmacophores of momelotinib and tandutinib to get a series of 4-piperazinyl-2-aminopyrimidine derivatives All compounds were tested for the inhibition of JAK2 and FLT3 enzymes, of which, compounds with potent enzyme activities were assayed for antiproliferative activities against three cancer cell lines (HEL, MV4-11, and HL60). The structure-activity relationship studies were conducted through variations in two regions, the “”A”” Ph ring and “”B”” Ph ring. Compound 14j showed the most balanced in vitro inhibitory activity against JAK2 and FLT3 (JAK2 IC50 = 27 nM, FLT3 IC50 = 30 nM), and it also showed potent inhibition against the above tested cell lines. In the cellular context, 14j strongly induced apoptosis by arresting cell cycle in the G1/S phase, and was selected as a promising JAK2/FLT3 dual inhibitor. After reading the article, we found that the author used 2,4-Dichloropyrimidine(cas: 3934-20-1Reference of 2,4-Dichloropyrimidine)
2,4-Dichloropyrimidine(cas: 3934-20-1) is a member of organic chlorides. Organic chloride content in crude oil can be detected through specialized laboratory analysis. Care and attention are essential while sampling and testing.Reference of 2,4-Dichloropyrimidine
