Biological Activity
AC50: 8 μM (PDK1)[1]
PDK1 activator, PS48, has the ability to reverse the cell proliferation inhibition role of Triptolide (HY-32735) in vitro. The inhibition role of Triptolide in cell number is significantly reversed by PS48. Triptolide significantly increases the cell proportion in G0-G1 phase and decreases the cell proportion in G2-M and S phase. However, the effect of Triptolide on cell cycle distribution is all reversed by PS48. In addition, suppression of PDK1/Akt/mTOR pathway by Triptolide in high glucose (HG)-treated human renal mesangial cells (HRMCs) is also reversed by PS48, as well as the expression of Ki-67 and proliferating cell nuclear antigen (PCNA)[2].

Protocol
PDK1 activity tests are performed using T308tide as a substrate for PDK1. In brief, PDK1 activity assay is performed at room temperature (22°C) in a 20 μL mix containing 50 mM Tris pH 7.5, 0.05 mg/mL BSA, 0.1% β-mercaptoethanol, 10 mM MgCl2, 100 μM [γ32P]ATP (5-50 cpm/pmol) , 0.003% Brij, 150-500 ng PDK1, and T308tide (from 0.1 to 1 mM). When appropriate, the PDK1 activity assay is performed in a 96 well format and 4 μL aliquots spotted on p81 phosphocellulose papers using ep motion 5070, washed in 0.01% phosphoric acid, dried, and then exposed and analysed using PhosphoImager technology. Activity measurements are performed in duplicates or triplicates with less than 10% difference between replicates. Experiments are repeated at least twice[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Human renal mesangial cells (HRMCs) are cultured with 1640 media, containing 10% fetal bovin serum at 37 °C in 5% CO2. Cells are cultured with D-glucose at normal (5.5 mM) or high (25 mM) concentrations in serum-free medium. D-Mannitol (25 mM) is used for a control of osmolality. TP is reconstituted in 0.01% DMSO and freshly diluted with culture medium to 10 ug/L before using. To determine the specific role of PDK1 in TP-potentiated anti-proliferation, 5 μM PS48 (MedChem Express, USA) is applied following the treatment of TP. MTT assay is used to detect cell proliferation. HRMCs are seeded at a density of 1x105/mL into 96-well plates. After 12, 24, 48 and 72 h incubation with different compounds, 20 uL MTT (5 mg/mL) is added to each well. Cells are then cultured for an additional 2 h and subsequently lysed using DMSO (150 uL/well). When the formazan crystals completely dissolve, the optical density (OD) is measured at 570 nm. The arithmetic mean OD of six wells for each group is calculated[2].
