| Features | A mechanism-based inhibitor of NAE, and creates a covalent NEDD8-MLN4924 adduct catalyzed by the enzyme. | ||||||||||||||||
| In vitro |
MLN4924 is structurally related to adenosine 59-monophosphate (AMP)—a tight binding product of the NAE reaction. MLN4924 (3 μM) selectively inhibits NAE in HCT-116 cell lysates. MLN4924 (3 μM) inhibits overall protein turnover by <9% in HCT-116 cells. MLN4924 results in a dose-dependent decrease of Ubc12–NEDD8 thioester and NEDD8–cullin conjugates with an IC50 < 0.1 μM in HCT-116 cells, resulting in a reciprocal increase in the abundance of the known CRL substrates CDT1, p27 and NRF2, but not non-CRL substrates. MLN4924 (3 μM) leads cells to accumulate in S-phase as early as 8 hours and results in a significant fraction of cells contained 4N DNA content by 24 hours in HCT-116 cells. [1] MLN4924 (3 μM) results in rapid accumulation of pIkappaBalpha, decrease in nuclear p65 content, reduction of nuclear factor-kappaB (NF-kappaB) transcriptional activity, and G(1) arrest, ultimately resulting in apoptosis induction, events consistent with potent NF-kappaB pathway inhibition in ABC DLBCL cells. [2] MLN4924 (1 μM) triggers DNA replication and inhibit cell proliferation by stabilizing the DNA replication factor Cdt1, a substrate of cullins 1 and 4. MLN4924 (1 μM) , which is sufficient to elevate Cdt1 for 4-5 hours, is found to be sufficient to induce DNA replication and to activate apoptosis and senescence pathways. [3] MLN4924 treatment induces the characteristics of senescence phenotypes as evidenced by enlarged and flattened cellular morphology and positive staining of senescence-associated β-Gal. MLN4924-induced senescence is associated with cellular response to DNA damage, triggered by accumulation of DNA-licensing proteins CDT1 and ORC1, as a result of inactivation of CRL/SCF E3s. MLN4924-induced senescence is irreversible and coupled with persistent accumulation of p21 and sustained activation of DNA damage response. [4] |

| In vivo | MLN4924 (60 mg/kg) results in a dose- and time-dependent decrease of NEDD8–cullin levels as early as 30 min after administration in HCT-116 tumour-bearing mice, with maximal effect 1–2 hours post-dose. MLN4924 (60 mg/kg) also leads to a dose- and time-dependent increase in the steady state levels of NRF2 and CDT1 in HCT-116 tumour-bearing mice. MLN4924 (60 mg/kg) leads to DNA damage in the tumour indicated by the increased levels of phosphorylated CHK1 in HCT-116 tumour-bearing mice. MLN4924 administered on a BID schedule at 30 mg/kg and 60 mg/kg inhibits tumour growth with T/C values of 0.36 and 0.15, respectively, in mice bearing HCT-116 xenografts. [1] MLN4924 (60 mg/kg) blocks NAE pathway biomarkers and results in complete tumor growth inhibition in mice bearing human xenograft tumors of ABC- and GCB-DLBCL. MLN4924 (60 mg/kg) results in NF-kappaB pathway inhibition accompanied by tumor regressions in primary human tumor mice models of ABC-DLBCL. [2] |
Protocol
| Kinase Assay:[1] |
- Collapse
In vitro E1-activating enzyme assays: A time-resolved fluorescence energy transfer assay format is used to measure the in vitro activity of NAE. The enzymatic reaction, containing 50 μL 50 mM HEPES, pH 7.5, 0.05% BSA, 5 mM MgCl2, 20 μM ATP, 250 μM glutathione, 10 nM Ubc12–GST, 75 nM NEDD8–Flag and 0.3 nM recombinant human NAE enzyme, is incubated at 24 ℃ for 90 min in a 384-well plate, before termination with 25 μL of stop/detection buffer (0.1 M HEPES, pH 7.5, 0.05% Tween20, 20 mM EDTA, 410 mM KF, 0.53 nM Europium-Cryptate-labelled monoclonal Flag-M2-specific antibody and 8.125 μg/mL PHYCOLINK allophycocyanin (XL-APC)-labelled GST-specific antibody. After incubation for 2 hours at 24 ℃, the plate is read on the LJL Analyst HT Multi-Mode instrument using a time-resolved fluorescence method. A similar assay protocol is used to measure other E1 enzymes. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Dilution Calculator
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
