MX69

MX69 is an inhibitor of the interaction between the ubiquitin ligase MDM2 protein and XIAP mRNA. It binds to the RING domain of MDM2 (Kd = 2.34 µM) and decreases the levels of MDM2 and XIAP in a concentration-dependent manner without affecting the levels of Bcl-2, cIAP-1, and cIAP-2. It induces autoubiquitination and degradation of MDM2 and increases the half-life of p53 in EU-1 cells. MX69 is cytotoxic to a variety of acute lymphoblastic leukemia (ALL) and neuroblastoma cancer cell lines but not to human normal bone marrow mononuclear (NBMM) cells. It increases survival in an EU-1 mouse model of leukemia when administered at a dose of 100 mg/kg.Formal Name: 4-[8-[[(3,4-dimethylphenyl)amino]sulfonyl]-3a,4,5,9b-tetrahydro-3H-cyclopenta[c]quinolin-4-yl]-benzoic acid.
