Biochem/physiol Actions
Massonianoside B is a cell-permeable, potent, highly selective, reversible and SAM-competitive DOT1L (disruptor of 4 telomeric silencing 1-like) inhibitor that decreases cellular levels of H3K79 methylation and inhibits the MLL fusion target genes HOXA9 and MEIS1 expression. Massonianoside B exhibits anti-leukemic activity. It is metabolically stable in both human and mouse liver microsomes.
