WDR5-IN-1 is a potent and selective inhibitor of WD repeat domain 5 (WDR5) (Kd <0.02 nM), and also inhibits MLL1 histone methyltransferase (HMT) activity (IC50: 2.2 nM).
MI-1481 is an effective MML1 inhibitor (IC50: 3.6 nM). MI-1481 showed very potent inhibition of the menin-MLL1 interaction (IC50: 3.6 nM). MI-1481 also demonstrates pronounced activity in MLL leukemia cells and in vivo in MLL leukemia models.
MM-401 is a specific inhibitor of histone H3K4 methyltransferase MLL1 activity that acts by reprogramming mouse epiblast stem cells to naive pluripotency.
Sekikaic acid is a phenolic lichen metabolite that has been found in H. obscurata and has diverse biological activities. It scavenges superoxide and DPPH radicals in cell-free assays when used at a concentration of 0.5 µM. Sekikaic acid is active against the rg recombinant strain of respiratory syncytial virus (RSV; IC50 = 5.69 µg ml). It inhibits the protein-protein interaction between mixed lineage leukemia 1 (MLL1) and the GACKIX domain of CREB-binding protein (CBP; IC50 = 34 µM).
TC-5115 is a potent inhibitor of MLL methyltransferase with IC50 value of 16 nM. TC-5115 may lead to the development of a new therapy for the treatment of human MLL leukemia. The mixed-lineage leukemia (MLL) protein, also known as MLL1, is a lysine methyltransferase specifically responsible for methylation of histone 3 lysine 4. MLL has been pursued as an attractive therapeutic target for the treatment of acute leukemia carrying the MLL fusion gene or MLL leukemia.
