生物活性
| 製品説明 | MLN4924は、Nedd8活性化酵素（NAE）の低分子阻害剤であり、IC50は4 nMです。 |
|---|---|
| in vitro | Pevonedistat (MLN4924) is structurally related to adenosine 59-monophosphate (AMP)—a tight binding product of the NAE reaction. It (3 μM) selectively inhibits NAE in HCT-116 cell lysates and inhibits overall protein turnover by <9% in HCT-116 cells. This compound 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. It (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. At the same concentration, it 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. At 1 μM, it triggers DNA replication and inhibits cell proliferation by stabilizing the DNA replication factor Cdt1, a substrate of cullins 1 and 4. This concentration, 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. Treatment with this compound 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. It is irreversible and coupled with persistent accumulation of p21 and sustained activation of DNA damage response. |
| in vivo | Pevonedistat (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. It also leads to a dose- and time-dependent increase in the steady state levels of NRF2 and CDT1 in HCT-116 tumour-bearing mice. This compound leads to DNA damage in the tumour indicated by the increased levels of phosphorylated CHK1 in HCT-116 tumour-bearing mice. When administered on a BID schedule at 30 mg/kg and 60 mg/kg, it inhibits tumour growth with T/C values of 0.36 and 0.15, respectively, in mice bearing HCT-116 xenografts. It (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. This compound (60 mg/kg) results in NF-kappaB pathway inhibition accompanied by tumor regressions in primary human tumor mice models of ABC-DLBCL. |

| 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. | ||
