|Description||(+)-Borneol is one of enantiomers of borneol which is a valuable medical material, senior aromatic spice, and chemical material and has been used in food and also folk medicine.|
(+)-borneol significantly inhibits the expression of iNOS and TNF-α in a dose-dependent manner in the LPS-stimulated BV-2 cells. Aβ-induced cell cytotoxicity is inhibited by 100 μM of (−) and (+) borneol treatment. Treatment of borneol significantly decreases ROS generation. The expression of HO-1 and nuclear translocation of Nrf2 are increased by Aβ treatment. This nuclear translocation of Nrf2 is further increased by administration of borneol. Compared with the Aβ treated group, the (+) borneol treated group significantly increases Bcl-2 expression with decreased expression of Bax. Thus, Borneol protects SH-SY5Y cells against Aβ-induced toxicity, exerts an antioxidative effect and suppresses apoptosis.
|In vivo||In the rat model of permanent cerebral ischemia, (+)-borneol (1.0 mg/kg) significantly ameliorates infarct size and neurological scoresvia reducing the expression of inducible nitric oxide synthase (iNOS) and tumor necrosis factor-alpha (TNF-α) in a dose dependent manner. Notably, (+)-borneol shows long-term effects on the improvement of sensorimotor functions in the photothrombotic model of stroke, which decreases the number of foot faults in the grid-walking task and forelimb asymmetry scores in the cylinder task, at least in part through reducing loss of dendritic spines in the length, brunch number and density. (+)-Borneol obviously loosens the intercellular tight junction in the blood-brain barrier (BBB) and enhances the distribution of drugs in the brain tissue, as it could increase number and volume of pinocytotic vesicles in BBB cells and then promotes the transportation of substance by cell pinocytosis. It contributes to neuroprotection and reduces pro-inflammatory cytokine expression and promotes functional recovery from permanent stroke with a long-term effect in the acute phase of focal permanent cerebral ischemia.|

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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 SDS / 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 SDS / 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.
