Design and synthesis of new anticancer pyrimidines with multiple-kinase inhibitory effect

Abstract

A new series of N-substituted-2-aminopyrimidines based on the '4-(pyridin-3-yl)pyrimidin-2-amine' scaffold of Imatinib has been designed and synthesized. A selected group from the target compounds was tested over a panel of 60 cancer cell lines at a single dose concentration of 10 mu M, and the two most active compounds, 25b and 30, were further tested in a five-dose testing mode to determine their IC50 values over the 60 cell lines. Compound 30 has showed good potencies and high efficacies, and was accordingly tested at a single dose concentration of 10 mu M over a panel of 54 kinases. At this concentration, the compound has showed multiple inhibitions over a number of oncogenic kinases, including ABL1, AKT1, LCK, C-SRC, PIM1, FLT3, FYN, and KDR. A molecular modeling study was made by docking of the most active compound 30 and its inactive analog 29 into the kinase domain of ABL1 to investigate their possible binding interactions.
