Description

OSU-03012 (AR-12; PDK1 inhibitor AR-12) is a blood-brain permeable PDK-1 inhibitor with an IC50 of 5 μM[1][3].

IC50 & Target

IC50: 5 μM (PDK-1)[1]
In Vitro

OSU-03012 inhibits PC-3 cells viability with IC50 values of 5 μM. The effects of OSU-03012 on PC-3 cell proliferation in 10% FBS-supplemented medium are also examined. OSU-03012 induces apoptotic death in PC-3 cells in 1% FBS-containing medium in a dose-dependent manner, as demonstrated by DNA fragmentation and PARP cleavage. OSU-03012 is effective in suppressing PC-3 cell proliferation at sub-μM, consistent with that noted in 1% serum[1].

In Vivo

All of the SCID/Rag2 mice develop two MDA-MB-435/LCC6/Her-2 tumors and are assigned to either the vehicle control or OSU-03012 (200 mg/kg) treatment group, which is given orally for 3 days. OSU-03012 remarkably decreases EGFR protein expression in the tumors by ~48% compared with expression levels found in the tumors taken from mice that receive the vehicle control. OSU-03012 also prevents Y-box binding protein-1 (YB-1) from binding to the EGFR promoter at the 1b and 2a sites[2].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (5.43 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.

    Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (5.43 mM); Suspended solution; Need ultrasonic

    This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Cell Assay
[1]

PC-3 (p53-/-) human androgen-nonresponsive prostate cancer cells are cultured in RPMI 1640 supplemented with 10% fetal bovine serum (FBS) at 37°C in a humidified incubator containing 5% CO2. The effect of Celecoxib and its derivatives (e.g., OSU-03012) (2.5 μM, 5 μM, 7.5 μM and 10 μM) on PC-3 cell viability is assessed by using the MTT assay in six replicates. Cells are grown in 10% FBS- supplemented RPMI 1640 in 96-well, flat-bottomed plates for 24 h, and are exposed to various concentrations of Celecoxib derivatives (e.g., OSU-03012) dissolved in DMSO (final concentration ≤0.1%) in 1% serum-containing RPMI 1640 for different time intervals. Controls receive DMSO vehicle at a concentration equal to that in drug-treated cells. The medium is removed, replaced by 200 μL of 0.5 mg/mL of MTT in 10% FBS-containing RPMI 1640, and cells are incubated in the CO2 incubator at 37°C for 2 h. Supernatants are removed from the wells, and the reduced MTT dye is solubilized in 200 μL/well DMSO. Absorbance at 570 nm is determined on a plate reader[1].

Animal Administration
[2]

Mice[2]
SCID/Rag2m mice (6-8 weeks old, female) are subcutaneously injected with 1×107 MDA-MB-435/LCC6 cells stably transfected with HER-2/neu. Each mouse is inoculated with the cells on the right and left sides of the lower back. A total of eight mice are injected, each harboring two tumors. After 6 weeks, the mice are randomly assigned into groups (vehicle, 0.5% methyl cellulose/0.1% Tween 80, or OSU-03012 at 200 mg/kg/day). Mice are dosed daily for 3 days with either the vehicle or OSU-03012 by oral gavage. On the fourth day, the study is terminated, mice are sacrificed, and the tumors are collected for chromatin immunoprecipitation (ChIP) and protein isolations.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
