General description

A cell permeable, non-toxic compound with a purine core scaffold that acts as a highly potent inhibitor of monopolar spindle1 kinase (MPS1; IC₅₀ = 50 nM). Displays good selectivity when screen against a panel of 450+ protein kinases. Reduces the levels of cyclin B that can be reversed by addition of proteasome inhibitor MG-132 (Cat. No. 474790). Inhibits SMAD2 phosphorylation and blocks the proliferation of U251 glioblastoma cells (IC₅₀ = 5 µM). Increasingly sensitizes U251 cells to the action of vincristine (~ 3 nM) in vitro and in orthotopic mouse model of glioblastoma (2 mg/kg) leading to their prolonged survival.
