Background

25(S)-27 hydroxy Cholesterol is a stereoisomer of the endogenous oxysterol 27-hydroxy cholesterol. 27-hydroxy Cholesterol is a sterol 27-hydroxylase-mediated cholesterol hydroxylation product involved in activating LXRα and LXRβ and potently suppressing cholesterol biosynthesis [1,2].

Liver X receptors (LXRs) belong to the nuclear receptor superfamily member. LXRs are ligand-activated transcription factors containing two LXR isoforms termed as α and β. LXRs play central roles in the transcriptional control of lipid metabolism. LXRs function as nuclear cholesterol sensors that are activated in response to elevated intracellular cholesterol levels in multiple cell types. Activation of LXRs induces the expression of the genes involved in cholesterol absorption, transport, efflux, and excretion. LXRs are potential targets for a variety of diseases, such as hypertriglyceridemia [3]. LXRs have also been involved in modulating immune and inflammatory responses in macrophages [3].

25(S)-27 hydroxy Cholesterol was the less predominant-occurring (~20%) stereoisomer of the endogenous oxysterol 27-hydroxy cholesterol. 27-hydroxy Cholesterol activated LXRα and LXRβ with the EC50 values of 85 and 71 nM, respectively [1,2].

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
