Use | MI-503 is a potent and selective Menin-MLL inhibitor with IC50 = 14.7 nM. MI-503 shows antitumor activity in in vitro and in vivo models of HCC and reveals the potential mechanism of menin contribution to HCC. Treatment with MI-503 selectively kills various HCC cell lines and this effect is significantly enhanced by a combination of MI-503 with sorafenib, the standard-of-care therapy for HCC. |
In vitro study | Treatment of mouse bone marrow cells (BMC) transformed with MI-503 of the oncogene with MLL-AF9 resulted in significant growth inhibition, with GI50 = 0.22 μm after 7 days of treatment. The MI-503 inhibition of cell growth was time-dependent and significant after 7-10 days of treatment. MI-503 is very effective in inducing MLL white blood cell differentiation, and can greatly enhance the expression of CD11b (CD11b is a marker of bone marrow differentiation), accompanied by c-kit (leukemia stem cell related marker). In MLL leukemia cells, treatment at <1 μm of MI-503 also resulted in a significant decrease in Hoxa9 and Meis1 expression levels, with a large upregulation of the downstream target genes of the MLL fusion protein. |
In vivo study | MI-503 has good drug class properties in mice, including metabolic stability, pharmacokinetics. It is able to prevent hematologic malignancies and reduce MLL leukemia tumor burden in vivo. After intravenous or oral administration of words, high levels can be achieved in peripheral blood MI-503, and oral bioavailability is also high (-75%). Prolongation of the treatment time by MI-503 (38 days) caused no toxic effects in mice, no change in body weight and no change in liver and kidney tissue morphology. MI-503 can greatly improve the survival of MLL leukemia mice, without affecting the normal hematopoietic function. |

biological activity | MI-503 is an effective and selective Menin-MLL inhibitor with IC50 of 14.7 nM. In human MLL leukemia cell lines, there is a significant growth inhibition effect (GI = 250 nM-570 nM), but in human leukemia cells without MLL translocation, the effect is very small. MI-503 is used to inhibit menin-MLL interactions that prevent the progression of MLL leukemia in vivo. |

It is able to block hematological malignancies in the body and reduce the MLL leukemia tumor burden. After intravenous injection or oral administration of words, the MI-503 can reach a high level in the peripheral blood and its oral bioavailability is also very high (~ 75%).
