• Description: HM43239 is an orally active small molecule inhibitor of FLT3 that selectively inhibits not only FLT3 wild type, ITD mutants or TKD mutations, but also FLT3 ITD/TKD double mutations. HM43239 directly inhibits the kinase activity of FLT3 as a reversible Type I inhibitor and effectively modulates downstream p-STAT5 and p-ERK. HM43239 also demonstrated inhibition of SYK, JAK1/2 and TAK1, known to be involved in tumor cell proliferation and/or differentiation HM43239 monotherapy induced dose-dependent regression of tumor growth in FLT3 wild-type and FLT3 mutated leukemia cancer cell line.

• In Vitro Activity: HM43239 potently inhibited the growth of AML cell lines harboring FLT3 ITD mutation, such as MV4-11 (IC50: 1.3 nM), MOLM-13 (5.1 nM) and MOLM-14 (2.9 nM). Furthermore, HM43239 effectively inhibited the phosphorylation levels of FLT3 and of downstream kinases related with cell proliferation.; Reference: Cancer Res. 2018 July 1;78(13_Supplement):804. https://doi.org/10.1158/1538-7445.AM2018-804
• In Vivo Activity: Furthermore, the combination treatment of HM43239 with various reagents (e.g., IAP inhibitor, chemotherapy, etc) demonstrated synergistic efficacy in mouse models, xenografted with both MV-4-11 and MOLM-13 cell lines without any significant toxicity.; Reference: Cancer Res. 2019 July 1;79(13_Supplement):1293. https://doi.org/10.1158/1538-7445.AM2019-1293
