Biological Activity

Description PS-48 is an allosteric activator of phosphoinositide-dependent protein kinase-1 (PDK1).
PDK1 [1]
In vitro

The PDK1 agonist PS48 is able to promote the osteogenic ability of MC3T3-E1 cells treated with dexamethasone. The protein levels of p-AKT and p-mTOR are increased in MC3T3-E1 cells treated with dexamethasone after PS48 treatment.[2]

In vivo

In vivo, the PDK1 agonist PS48 can maintain the bone mass of mice treated with dexamethasone.[2]

Protocol (from reference)

Cell Research:


  • Cell lines: MC3T3-E1 cells
  • Concentrations: 5 μM
  • Incubation Time: --
  • Method:

    MC3T3-E1 cells are cultured in an osteogenic differentiation medium containing 4 mM glycerophosphate and 25 μg/mL ascorbic acid until 70% confluency. Dexamethasone (final concentration of ethanol, 0.01%, vol/vol) at different concentrations is then added to the osteogenic differentiation medium for 14 days. The culture medium is replaced every two days. MC3T3-E1 cells are cultured in a culture medium containing 10−7 M dexamethasone supplemented with or without PS48 (5 μM).

Animal Research:


  • Animal Models: 8-week-old male C57BL/6J mice
  • Dosages: --
  • Administration: --

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.
