DPBQ

Catalog No.GC33384

DPBQ activates p53 and triggers apoptosis in a polyploid-specific manner, but does not inhibit topoisomerase or bind DNA. DPBQ elicits expression and phosphorylation of p53 and this effect is specific to tetraploid cells.

Description of DPBQ

DPBQ is a p53 activator.

DPBQ elicits apoptosis and cell death and is selective for effects in 4N cells. DPBQ elicits expression and phosphorylation of p53 and this effect is specific to tetraploid cells. Knockdown of TP53 restores proliferation of tetraploid cells in the presence of DPBQ[1].

Protocol of DPBQ

Kinase experiment:

For Western blot analysis, 2N and 4N RPE1 cells are treated with DMSO, 50 ng/mL doxorubicin, or 1 μM DPBQ for 48 hours. Western blotting is performed with a SDS-PAGE Electrophoresis and semidry transfer. Samples are analyzed by chemiluminescence. β-actin is used as a protein loading control[1].

Cell experiment:

For Apoptosis assays, 2N and 4N RPE1 cells are treated with DMSO, 60 nM staurosporine, or 1 μM DPBQ for 48 hours. Apoptosis is evaluated by an Annexin V-PE/7-AAD apoptosis detection kit. For the flow cytometry analysis, the percent positive cells in the upper right and lower right quadrants are summed to give the total number of apoptotic cells. Three independent replicates are performed[1].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
