MEL23
MEL23 is a MDM2 E3 ligase inhibitor that blocks the E3 ligase activity of the MDM2-MDMX complex. MEL23 inhibits Mdm2 and p53 ubiquitination in cells, reduce viability of cells with wild-type p53. MEL23 stabilizes MDM2 via a mechanism independent of p53 transcription.

MDM2 |
MEL23 increases the luminescence of Mdm2(wt)-luciferase cells with an EC50 value of 2.7 μg/mL[1].
MEL23 (3.16-100 μM; 48 hours) leads to cell death that is p53-dependent[1].
MEL23 (2.5-5 μg/mL; 48 hours) increases the sub-G1 population and caused a slight G2-cell cycle arrest in HT-1080 cells[1].
MEL23 (5 μg/mL; 6 hours) increases levels of Mdm2, p53, and MdmX and activates p53[1].
MEL23 (5 μg/mL; 24-48 hours) increases the transcription of p53 target genes, Mdm2, p21, puma, and bax[1].
In the parental HT-1080 cells, MEL23 suppresses cell death induced by Erastin (HY-15763), and substantially decreases the extent of ferroptosis[2].
