Betulin (BE), also known as betulinol, betuline, or betulinic alcohol, is a pentacyclic lupane-type triterpenoid naturally distributed in many plants and displays a broad spectrum of biological and pharmacological properties such as anticancer and chemopreventive activity. Betulin (Trochol), is a sterol regulatory element-binding protein (SREBP) inhibitor with an IC50 of 14.5 μM in K562 cell line.

|Description||Betulin (BE), also known as betulinol, betuline, or betulinic alcohol, is a pentacyclic lupane-type triterpenoid naturally distributed in many plants and displays a broad spectrum of biological and pharmacological properties such as anticancer and chemopreventive activity. Betulin (Trochol), is a sterol regulatory element-binding protein (SREBP) inhibitor with an IC50 of 14.5 μM in K562 cell line.|
Betulin significantly inhibits cell viability in cervix carcinoma HeLa cells, hepatoma HepG2 cells, lung adenocarcinoma A549 cells, and breast cancer MCF-7 cells with IC50 values ranging from 10 to 15 mg/mL. While betulin exhibits only moderate anticancer activity in other human cancer cells such as hepatoma SK-HEP-1 cells, prostate carcinoma PC-3, and lung carcinoma NCI-H460, with IC50 values ranging from 20 to 60 mg/mL, it shows minor growth inhibition in human erythroleukemia K562 cells (IC50>100 mg/mL). Betulin does not directly trigger mitochondrial cytochrome c release in isolated mitochondria. Bax and Bak are rapidly translocated to the mitochondria 30 min after betulin treatment. In vitro, Betulin inhibits LPS-induced tumor necrosis factor α (TNF-α) and (interleukin) IL-6 levels and up-regulates the level of IL-10. Also Betulin suppresses the phosphorylation of nuclear factor-kB (NF-kB) p65 protein in LPS-stimulated RAW 264.7 cells.
|In vivo||In vivo, Betulin alleviates LPS-induced acute lung injury. Treatment with Betulin diminishes pro-inflammatory cytokines, myeloperoxidase activity and bacterial loads in lung tissue during gramnegative pneumonia. In HFD-fed apoE−/− mice, betulin administration significantly reduces lesions in en face aortas and aortic sinuses. Furthermore, betulin administration significantly increases ABCA1 expression and suppresses macrophage positive areas in the aortic sinuses. Moreover, betulin administration improves plasma lipid profiles and enhances fecal cholesterol excretion in the mice.|

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.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
