Biological Activity
GSK2945 dose-dependently enhances the transcriptional activity of Rev-erbα and a Bmal1 (a target gene of REV-ERBs) luciferase reporter (EC50 of 2.05 μM)[1].
GSK2945 (20 μM; 12 hours and 24 hours; mouse and human primary hepatocytes) treatment increases levels of Cyp7a1/CYP7A1 in mouse and human primary hepatocytes. GSK2945 (20 μM) treatment also increases Lrh-1/LRH-1 (a known hepatic activator of Cyp7a1/CYP7A1) mRNA and protein[1].

-
Cell Line:Mouse (male, CD1) and human (male, Caucasian) primary hepatocytes
-
Concentration:20 μM
-
Incubation Time:12 hours and 24 hours
-
Result:Led to significant increases in mRNA and protein (at 24-h) expression of Cyp7a1. mRNA and protein (at 24-h) levels of CYP7A1 were increased in human primary hepatocyte. Lrh-1/LRH-1 was upregulated.

Animal Model:Male C57BL/6 mice (8-10 weeks of age)[1]
-
Dosage:0 mg/kg or 10 mg/kg
-
Administration:Intraperitoneal injection; twice every day; for 7 days
-
Result:Increased hepatic mouse cholesterol 7α-hydroxylase (Cyp7a1) level and lowered plasma cholesterol in wild-type mice.

Solvent & Solubility
DMSO : 83.33 mg/mL (197.77 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.08 mg/mL (4.94 mM); Clear solution
This protocol yields a clear solution of ≥ 2.08 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (20.8 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.
