Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 10.000mg/ml (17.20mM) Taking the 1 mL working solution as an example, add 50 μL of 200 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 make it clear; 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 Nutlin-3a ((-)-Nutlin-3), the active enantiomer of Nutlin-3, inhibits the p53/MDM2 interaction with IC50 of 90 nM in a cell-free assay. Nutlin-3a induces autophagy and apoptosis in a p53-dependent manner.
Targets
p53-MDM2 interaction [3]
(Cell-free assay)
90 nM
In vitro Nutlin-3a displaces p53 from the binding pocket of MDM2 and thereby releases p53 from inhibition and proteasomal degradation, leading to induction of its downstream targets, cell cycle arrest, and apoptosis. Seven days of incubation with 10 μM nutlin-3a led to >90% inhibition of NIH3T3 cells’ growth[1]. Nutlin-3a stabilizes and activates p53, and induces p21 expression in a dose-dependent manner[1]. Nutlin-3a effectively depletes the S-phase compartment to 0.2-2% and increases the G1- and G2/M-phase compartments[1]. Nutlin-3a induces apoptosis in ~60% of SJSA-1 and MHM cells after 40 h, which increased further after 60 h (85% and 65%, respectively) [1].
In vivo Nutlin-3a suppresses xenograft growth in a dose-dependent fashion with the highest dose (200 mg/kg) showing a substantial tumor shrinkage [1]. Nutlin-3 is a selective activator of the p53 pathway in vivo and highly efficacious against SJSA-1 osteosarcoma tumors[1]. Tumors with wild-type p53 and mdm2 gene amplification will respond best to therapy with Nutlin-3a.
Features Highly selective MDM2 inhibitor with a much lower effect on MDMX. Most effective on tumors with wild type p53.

Protocol (from reference)

Kinase Assay:[3]
  • Biacore studies

    Competition assays are performed on a Biacore S51. A Series S Sensor chip CM5 is derivatized for immobilization of a PentaHis antibody for capture of the His-tagged p53. The level of capture is ~ 200 response units (1 response unit corresponds to 1 pg of protein per mm 2). The concentration of MDM2 protein is kept constant at 300 nM. Test compounds are dissolved in DMSO at 10 mM and further diluted to make a concentration series of inhibitor in each MDM2 test sample. The assays are run at 25 °C in running buffer (10 mM Hepes, 0.15 M NaCl, 2% DMSO). MDM2-p53 binding in the presence of inhibitor is calculated as a percentage of binding in the absence of inhibitor and IC50 is calculated using Microsoft Excel

Twenty-four hours after plating 1×105 Shh-EGFP cells, media was changed to serum-free media containing vehicle, 8µM Nutlin-3a, and/or Shh (3µg/mL). Cells were also transduced with lentivirus containing pLKO.1 empty vector or LentiORF-YFP-WIP1. 48 hours later, cells were fixed in 4% paraformaldehyde, permeabilized, incubated with α-WIP1 or α-Ki-67 antibody, and mounted using media containing DAPI. Scale bar, 100µm.
