Abstract

Acute myeloid leukemia (AML) is characterized by fast progression and low survival rates, in which Fms-like tyrosine kinase 3 (FLT3) receptor mutations have been identified as driver mutations in a subgroup of AML patients. Herein, we describe the design, synthesis, and biological evaluation of a novel series of potent pyrido.[3,4-b]pyrazin-2(1H)-one derivatives as FLT3 inhibitors. The compounds exhibited moderate to potent FLT3 kinase inhibitory potency and excellent antiproliferative activities against MV4-11 cells. Among them, compound 13 demonstrated the most potent kinase activity against FLT3-D835Y (IC50 = 29.54 ± 4.76 nM) and cellular potency against MV4-11 cells (IC50 = 15.77 ± 0.15 nM). Compound 13 also efficiently inhibited the growth of multiple mutant BaF3 cells expressing FLT3-D835V/F, FLT3-F691L, and FLT3-ITD/D835Y. Furthermore, compound 13 was metabolically stable in mouse liver microsomes. Moreover, the treatment with compound 13 led to robust inhibition of FLT3 autophosphorylation on Tyr589/591 in MV4-11 cells. In summary, our data demonstrated that 13 was worthy of further study for the treatment of AML.
