ML-792 is a potent, seletive SUMO-activating enzyme (SAE) inhibitor with IC50 of 3 nM and 11 nM for SAE/SUMO1 and SAE/SUMO2, respectively.
ML 792 shows no significant inhibition for closely related E1 enzymes NAE (IC50=32 uM) and ubiquitin-activating enzyme (UAE) (IC50 >100 uM), as well as a panel of 366 ATP-using enzymes.
ML 792 dose-dependently decreases global SUMOylation in HCT116 cells (EC50=19 nM), demonstrates potent antiproliferative effect in HCT116 cells and MDA-MB-231 cells with EC50 of 0.04 and 0.11 uM, respectively.
