Protocol

Cell experiment:

The effect of campesterol on the viable cell number was assessed by XTT assay. HUVECs were treated with various concentrations (10, 20, 30, 40 and 50 μg/mL) of campesterol and incubated at 37 °C in a humidified incubator for 24 h, a XTT working solution was added to each well. The cells were incubated at 37 °C for 2 h and the optical density was measured using a microplate reader at 450 nm[1].

Background

24α-methyl Cholesterol is an agonist of liver X receptors (LXR).

Liver X receptors (LXRs) are ligand-dependent transcription factors involved in the transcriptional control of lipid metabolism. LXRs function as nuclear cholesterol sensors that are activated by elevated intracellular cholesterol levels in multiple cell types. Activation of LXRs induces the expression of various genes involved in cholesterol absorption, transport, efflux, and excretion. In addition to their function in lipid metabolism, LXRs have also been found to modulate immune and inflammatory responses in macrophages. LXRα is highly expressed in the liver and at lower levels in the adrenal glands, adipose, intestine, lung, macrophages, and kidney, and LXRβ is ubiquitously expressed [2].

24α-methyl Cholesterol was a phytosterol found in vegetables, nuts, fruits, and seeds that competitively inhibited the absorption of intestinal cholesterol and decreased the transcription of genes important for cholesterol metabolism [3]. 24α-methyl Cholesterol acted as an agonist at liver X receptors (LXR) and suppressed the proliferation of prostate and breast cancer cells [1].

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.
