Dot1L-IN-4 is a potent disruptor of telomeric silencing 1-like protein (DOT1L) inhibitor with an IC50 SPA DOT1L of 0.11 nM[1].
Dot1L-IN-4 (Compound 10) is tested in cellular assays to assess the ability to inhibit the dimethylation of H3K79 in HeLa cells (ED50 H3K79me2 Elisa=1.7 nM) and HOXA9 gene expression in Molm-13 cells (ED50 HOXA9 RGA=33 nM). Dot1L-IN-4 also inhibits mixed lineage leukemia (MLL) with an IC50 of 99 µM[1].
Dot1L-IN-4 (Compound 10; 300 mg/kg; p.o.; qd) is not tolerated at such a high dose by tumor xenograft bearing mice, and at a 6-fold reduced dose, the tumor growth as well as the HOXA9 reporter gene mRNA are reduced only by less than half as compared to control animals[1].
