Lanosterol, a naturally-occurring triterpenoid derivative, is a key imtermediate in the biosynthesis of Cholesterol. Lanosterol is metabolized to Cholesterol and Cucurbitacins. Lanosterol is a naturally-occurring sterol and biosynthetic precursor of several animal, fungal, and protozoan steroids, including cholesterol and ergosterol. Defects in the processing of lanosterol contribute to a wide variety of disorders, including the formation of cataracts. Similarly, certain fungicides act by blocking lanosterol processing by fungi.
ln Vitro |
Through enhanced autophagy and co-chaperone CHIP expression, lanosterol reduces aberrant proteotoxic aggregation and lessens its cytotoxicity[1]. The oocyte is instructed to restart meiosis by lanosterol, which triggers a physiological signal in the cholesterol biosynthesis pathway and is a precursor of meiosis-activating sterols [2].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1 mg/mL (2.34 mM) (saturation unknown) in 10% EtOH + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear EtOH stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1 mg/mL (2.34 mM) (saturation unknown) in 10% EtOH + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear EtOH stock solution to 900 μL of corn oil and mix well.  (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
