AF9/ENL-DOT1L/AF4 PPI-IN-1 is a potent inhibitor of protein-protein interactions (PPI) between AF9/ENL and the histone methyltransferase DOT1L/AF4. It effectively inhibits the interactions of AF9-DOT1L (IC50= 1.5 μM), AF9-AF4 (IC50= 1 μM), and ENL-AF4 (IC50= 1.2 μM). This compound suppresses the expression of MLL target genes, Myc and Meis1, and selectively blocks the proliferation of MLL-r and other leukemia cells. In a mouse model of MLL-r leukemia, AF9/ENL-DOT1L/AF4 PPI-IN-1 demonstrates significant antitumor activity with no notable toxicity. It is a useful agent for studying MLL-r leukemia.

| In vitro | AF9/ENL-DOT1L/AF4 PPI-IN-1 (0-1 μM,3 days) significantly reduces the mRNA levels of Myc and Meis1 in a concentration-dependent manner in Molm-13 cells. AF9/ENL-DOT1L/AF4 PPI-IN-1 effectively and selectively inhibits a range of cancer cells, including MV4-11 (EC₅₀ = 0.96 μM), Molm-13 (EC₅₀ = 1.6 μM), NB4 (EC₅₀ = 2.7 μM), HL-60 (EC₅₀ = 0.66 μM), Kasumi (EC₅₀ = 0.92 μM), and Jurkat (EC₅₀ = 0.77 μM), while showing negligible antiproliferative activity against solid tumor HeLa cells (EC₅₀ > 30 μM). |
| In vivo | AF9/ENL-DOT1L/AF4 PPI-IN-1, administered at 25 mg/kg and 50 mg/kg twice daily via intraperitoneal injection for 14 days, demonstrates significant antitumor activity in an MLL-r leukemia NOD-SCID mouse model, with good tolerance at these dosages. Additionally, at 50 mg/kg via intraperitoneal injection (0.5-24 hours), it exhibits favorable pharmacokinetic properties in NOD-SCID mice, with satisfactory plasma drug exposure and a half-life exceeding 40 hours. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year Shipping with blue ice/Shipping at ambient temperature. |
