Biological Activity

Potent and selective dihydroorotate dehydrogenase (DHODH) inhibitor (IC50 = ~20 nM). Causes depletion of pyrimidine nucleotides. Exhibits minimal inhibition against a panel of >400 kinases. Triggers differentiation of AML cell lines (ED50 = ~ 1 μM. Note uridine concentration effects ED50 value). Causes differentiation and depletion of leukemia-initiating cells in vivo. Antimetabolite.
