GSK2945 is a class of tertiary amine, and is a highly specificRev-erbα/REV-ERBα (mouse/human reverse erythroblastosis virus α)antagonist withEC₅₀s of 21.5 μM and 20.8 μM, respectively. GSK2945 enhancescholesterol7α-hydroxylase (CYP7A1)level andcholesterolmetabolism^[1].

GSK2945 dose-dependently enhances the transcriptional activity of Rev-erbα and a Bmal1 (a target gene of REV-ERBs) luciferase reporter (EC₅₀of 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].

GSK2945 (0-10 mg/kg; intraperitoneal injection; twice every day; for 7 days; male C57BL/6 mice) treatment increases hepatic mouse cholesterol 7α-hydroxylase (Cyp7a1) level and lowers plasma cholesterol in wild-type mice^[1].

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照In Vitro方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用； 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

• 1.

  请依序添加每种溶剂： 10% DMSO    40%PEG300   5%Tween-80   45% saline

  Solubility: ≥ 2.08 mg/mL (4.94 mM); Clear solution

  此方案可获得 ≥ 2.08 mg/mL (4.94 mM，饱和度未知) 的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH2O 中，得到澄清透明的生理盐水溶液

  请依序添加每种溶剂： 10% DMSO    90%corn oil

  Solubility: ≥ 2.08 mg/mL (4.94 mM); Clear solution

  此方案可获得 ≥ 2.08 mg/mL (4.94 mM，饱和度未知) 的澄清溶液，此方案不适用于实验周期在半个月以上的实验。

  以 1 mL 工作液为例，取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。
