24S,25-Epoxycholesterol (1-10 μM) upregulates LXR-related genes ABCA1, ABCG1, and APOE, promotes cholesterol efflux, thereby preventing foam cell formation, and blocks the proliferation of mouse and human glioma stem cells by eliminating cellular cholesterol[1][3]. 24S,25-Epoxycholesterol inhibits the proliferation and migration of HGC27, which is enhanced by knockout of LXRβ[2]. 24S,25-Epoxycholesterol (40 μM) inhibits HMG-CoA reductase and activates LXR, thereby inhibiting mevalonate-dependent isoprenoid production and enhancing ATP-binding cassette transporter G1 expression, inducing apoptosis of bone marrow-derived mouse mast cells (BMMC)[5].

| Additional Infomation |
24(S),25-epoxycholesterol is a 3beta-hydroxy-Delta(5)-steroid that is desmosterol in which the double bond at position 24-25 has been oxidised to the corresponding epoxide (the 24S diastereoisomer). It is an oxysterol agonist of the liver X receptor. It has a role as a liver X receptor agonist. It is a cholestanoid, a 3beta-hydroxy-Delta(5)-steroid and an epoxy steroid. It is functionally related to a desmosterol.

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).

Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] Oral Formulations
Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.4960 mL | 12.4800 mL | 24.9601 mL | |
| 5 mM | 0.4992 mL | 2.4960 mL | 4.9920 mL | |
| 10 mM | 0.2496 mL | 1.2480 mL | 2.4960 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
