PIK-75 alone blocks Thr 308 phosphorylation in L6 myotubes and 3T3-L1 adipocytes with IC₅₀ values of 1.2 and 1.3 μM, respectively^[1].
PIK-75 (1-1000 nM; 5 min) blocks the phosphorylation of PKB induced by insulin on both Ser473and Thr308 in CHO-IR cells in a dose-dependent manner, with an IC₅₀ of 78 nM^[2].
PIK-75 (0.1-1000 nM; 48 hours) inhibits the proliferation and survival of pancreatic cancer cells through apoptotic cell death^[3].
PIK-75 (0.1-1000 nM) also reduces the colony formation of pancreatic cancer MIA PaCa-2 and AsPC-1 cells^[3].

Cell Viability Assay^[3]

Cell Line:	Human pancreatic cancer cells (MIA PaCa-2 or AsPC-1)
Concentration:	0.1, 0.3, 1, 3, 10, 30, 100, 300, and 1000 nM
Incubation Time:	48 hours
Result:	Submicromolar concentration was sufficient to inhibit the proliferation of pancreatic cancer, MIA PaCa-2 and AsPC-1 cells after 48-h treatment.

Western Blot Analysis^[2]

Cell Line:	Overnight-starved CHO-IR cells
Concentration:	1, 10, 100, 1000 nM
Incubation Time:	5 minutes
Result:	Blocked the phosphorylation of PKB induced by insulin (1 nM, 10 min) on both Ser473and Thr308 in a dose-dependent manner.

In Vivo

PIK-75 (2 mg/kg) potentiates anticancer activity of Gemcitabine (20 mg/kg) in vivo. Gemcitabine (20 mg/kg) or PIK-75 (2 mg/kg) alone reduces the tumor growth to similar degree. Beneficial effect of PIK-75/Gemcitabine is evident as this combination markedly reduces the tumor growth in vivowithout affecting the body weights of mice^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Mice bearing tumors of MIA PaCa-2^[3]
Dosage:	2 mg/kg; or combination with Gemcitabine (20 mg/kg)
Administration:	Administered injection; 5 times per week. 25 days
Result:	Reduced the tumor growth and enhanced the antitumor effect.

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: ≥ 1.1 mg/mL (2.25 mM); Clear solution

This protocol yields a clear solution of ≥ 1.1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (11.0 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: ≥ 1.1 mg/mL (2.25 mM); Clear solution

This protocol yields a clear solution of ≥ 1.1 mg/mL (saturation unknown).

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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 1.1 mg/mL (2.25 mM); Clear solution

This protocol yields a clear solution of ≥ 1.1 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
