简介内容:FI-700 is a novel and potent FLT3 inhibitor with promising antileukemia activity. FI-700 showed a potent IC(50) value against FLT3 kinase at 20 nmol/L in an in vitro kinase assay. FI-700 showed selective growth inhibition against mutant FLT3-expressing leukemia cell lines and primary acute myeloid leukemia cells, whereas it did not affect the FLT3 ligand (FL)-driven growth of Wt-FLT3-expressing cells. Oral administration of FI-700 induced the regression of tumors in a . tumor xenograft model
