Description:	VTP50469 is a potent, highly selective and orally active Menin-MLL interaction inhibitor with a Ki of 104 pM. VTP50469 has potently anti-leukemia activity[1][2].
Target:	Ki: 104 pM (Menin-MLL interaction)[1][2]
In Vivo:	VTP50469 (15-60 mg/kg; oral administration; twice a day; for 28 days; NSG mice) treatment is highly efficacious across all dosage levels and all treatment groups have a significant survival advantage. Mice dosed at 30 and 60 mg/kg VTP50469 extends survival advantage[1]. Animal Model: Unconditioned immunodeficient (NSG) mice with MV4;11 cells[1] Dosage: 15 mg/kg, 30 mg/kg, and 60 mg/kg Administration: Oral administration; twice a day; for 28 days Result: Was highly efficacious across all dosage levels and all treatment groups had a significant survival advantage over the control group.
In Vitro:	VTP50469 more potently and rapidly inhibits cell proliferation in a concentration-dependent manner in MLL-r cell lines carrying (MOLM13 (IC50 of 13 nM), THP1 (IC50 of 37 nM), NOMO1 (IC50 of 30 nM), ML2 (IC50 of 16 nM), EOL1 (IC50 of 20 nM), and murine MLL-AF9 cells (IC50 of 15 nM)) and ALL (KOPN8 (IC50 of 15 nM), HB11;19 (IC50 of 36 nM), MV4;11 (IC50 of 17 nM), SEMK2 (IC50 of 27 nM), and RS4;11 (IC50 of 25 nM)) cell lines[1]. At early timepoints MLL-r B cell ALL (B-ALL) cell lines, but not MLL-r AML cell lines, underwent apoptosis in response to VTP50469 in a dose-dependent manner. MLL-r AML cell lines underwent dose-dependent differentiation starting at 4-6 days of exposure to VTP50469[1]. VTP50469 displaces Menin from protein complexes and inhibits chromatin occupancy of MLL at select genes. Loss of MLL binding led to changes in gene expression, differentiation, and apoptosis[1].
