General description

A cell-permeable tetrahydro-β-carbolinylbarbiturate compound that selectively inhibits the E3 ligase activity of Mdm2-MdmX hetero-complex over that of Mdm2-Mdm2 homo-complex (70.6% vs. 17.6% inhibition, respectively, at 100 µM), without affecting Mdm2-MdmX complex formation or the activity of two other UbcH5C-utilizing ligase complexes Roc1-Cul1 and BRCA1-BARD1. Effectively inhibits ubiquitination and proteasomal degradation of cellular Mdm2 and p53 (effective conc. = 14 µM in U2OS, RKO, and HCT116 cultures) and induce RKO and MEF cell death in a p53- and Mdm2-dependent manner. Unlike Nutlin-3 (Cat. Nos. 444143 & 444151), MEL23 does not interfere with Mdm2-p53 interaction.

Effectively inhibits Mdm2-MdmX E3 ligase activity-dependent ubiquitination and proteasomal degradation of cellular Mdm2 and p53 (effective conc. = 14 µM in U2OS, RKO, and HCT116 cultures) and prevents DNA damage-induced MdmX degradation in MCF7 cells upon 50 µM etoposide treatment. Shown to induce RKO and MEF cell death in a p53- and Mdm2-dependent manner. Unlike Nutlin-3 (Cat. Nos. 444143 & 444151), MEL23 does not act by interfering Mdm2-p53 interaction.

The p53 tumor suppressor protein, known to be critically important in several processes including cell-cycle arrest and apoptosis, is highly regulated by multiple mechanisms, most certifiably the Murine Double Minute 2-Murine Double Minute X (MDM2-MDMX) heterodimer. The role of MDM2-MDMX

Although the E3 ligase Mdm2 and its homologue and binding partner MdmX are the major regulators of the p53 tumor suppressor protein, it is now evident that Mdm2 and MdmX have multiple functions that do not involve p53. As one
