MAX-40279 hemiadipate is also effective against the FLT3 mutants such as FLT3^D835Y, suggesting that it can overcome resistance to Quizartinib (HY-13001) and Sorafenib (HY-10201). MAX-40279 hemiadipate inhibits NDRG1 phosphorylation at Ser330 and suppresses endothelial-to-mesenchymal transition (EndMT). MAX-40279 hemiadipate can be used for the research of acute myelogenous leukemia (AML).

Enzomenib enantiomer (DSP-5336 enantiomer) is an enantiomer of Enzomenib (HY-156794). Enzomenib (DSP-5336) is an orally active Menin inhibitor (IC₅₀=1.4 nM, K_d=6.0 nM). Enzomenib disrupts the interaction between Menin and KMT2A/MLL fusion proteins, specifically inhibits the expression of leukemia driver genes such as HOX/MEIS1, and upregulates ITGAM. Enzomenib effectively induces cell differentiation, inhibits tumor cell proliferation, and suppresses primitive cell colony formation. Enzomenib reduces disease burden and prolongs survival, but causes adverse reactions including differentiation syndrome and QTc interval prolongation. Enzomenib is used for research on relapsed/refractory acute myeloid leukemia, acute lymphoblastic leukemia, and other hematologic malignancies with mixed lineage leukemia (MLL) rearrangements or NPM1 mutations.
