0.625mg/ml Taking the 1 mL working solution as an example, add 50 μL of 12.5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description ML-792 is a potent and selective inhibitor of SUMO (small ubiquitin-like modifier)-activating enzyme (SAE). ML-792 inhibits SAE/SUMO1 and SAE/SUMO2 in ATP–inorganic pyrophosphate (PPi) exchange assays with IC50 of 3 nM and 11 nM, respectively.
Targets
SAE/SUMO1 [1]
(Cell-free assay)		 SAE/SUMO2 [1]
(Cell-free assay)
3 nM 11 nM
In vitro

ML-792 is a mechanism-based SUMO-activating enzyme (SAE) inhibitor with nanomolar potency in cellular assays. ML-792 selectively blocks SAE enzyme activity and total SUMOylation, thus decreasing cancer cell proliferation. Induction of the MYC oncogene increases the ML-792-mediated viability effect in cancer cells, thus indicating a potential application of SAE inhibitors in treating MYC-amplified tumors.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    HCT116 cells

  • Concentrations

    0.5 μM

  • Incubation Time

    48 h

  • Method

    HCT116 cells are plated (0.2 × 106 cells/well) and incubated overnight in six-well tissue culture dishes. To study ML-792-induced DNA damage, cells are then treated with DMSO or 0.5 μM ML-792 for 24 h. A 4-h treatment is used as a positive control for induction of DNA-strand breaks. To study how loss of SUMOylation contributes to repair of DNA damage, individual wells of HCT116 cells are treated with the following treatments: DMSO (6 h); 0.5 μM ML-792 (6 h).
