BPR1J-340 is a potent and selective FLT3 inhibitor with potential anticancer activity. BPR1J-340 was identified as a novel potent FLT3 inhibitor by biochemical kinase activity (IC50 approximately 25 nM) and cellular proliferation (GC50 approximately 5 nM) assays. BPR1J-340 inhibited the phosphorylation of FLT3 and STAT5 and triggered apoptosis in FLT3-ITD(+) AML cells. The pharmacokinetic parameters of BPR1J-340 in rats were determined. BPR1J-340 also demonstrated pronounced tumor growth inhibition and regression in FLT3-ITD(+) AML murine xenograft models. The combination treatment of the HDAC inhibitor vorinostat (SAHA) with BPR1J-340 synergistically induced apoptosis via Mcl-1 down-regulation in MOLM-13 AML cells, indicating that the combination of selective FLT3 kinase inhibitors and HDAC inhibitors could exhibit clinical benefit in AML therapy.
Uses
BPR1J-340 is a potent FLT3 inhibitor with an IC50 of ~25 nM. BPR1J-340 inhibits the phosphorylation of FLT3 and STAT5 and triggered apoptosis in FLT3-ITD+ acute myeloid leukemia (AML) cells. BPR1J-340 exhibits significant anti-tumor activities[1].
