Home Ubiquitin E3 Ligase inhibitor - Apoptosis related activator SZL P1-41 For research use only.

SZL P1-41

SZL P1-41 (compound #25) is a specific inhibitor of S-phase kinase-associated protein 2 (Skp2) that indeed binds to Skp2, prevents Skp2-Skp1 interaction and inhibits Skp2 SCF E3 ligase activity, which consequently suppresses survival of cancer cells and cancer stem cells. SZL P1-41 causes higher apoptosis rates in cancer cells.

Cell Research Cell lines PC3 cells
Concentrations 10 μM, 20 μM
Incubation Time 4 days
Method

For Skp2 inhibitor administration, 5~10 × 103 of cells are seeded in 12 wells in triplicate for 24 h and then treated with various doses of SZL P1-41 (refreshed every two days). After four days, cells are harvested, stained with 0.4% blue solution, and viable cells are counted using hemocytometer under microscope by blue dye exclusion method. For treatment, 8× 103 of PC3 cells with were seeded in 12 wells in triplicate for 24 h and then treated with various doses of SZL P1-41 for four and three days, respectively (refreshed every two days).

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.
