The flux ratios of [14C]Bepotastine (5 μM) in LLC-GA5-COL150 cells are significantly greater than those in LLC-PK1, showing that the B-to-A flux exceeds those in the other direction in LLC-GA5-COL150 cells. Bepotastine stimulates P-gp-mediated ATP hydrolysis with Km, Vmax, and Vmax/Km values of 1.25 mM, 108 nmol/min/mg protein, and 0.087 mL/min/mg protein, respectively. [2] Bepotastine besilate (100 mM) suppresses Leukotriene B(4) induced Ca(2+) concentration in cultured dorsal root ganglion neurons and cultured neutrophils. [3] Bepotastine (100 μM) dose-dependently inhibits chemotaxis of cultured guinea pig peritoneal eosinophils induced by LTB4. Bepotastine (1 mM) significantly reduces A23187-induced histamine release of cultured rat peritoneal mast cells. [4] |

| In vivo | Bepotastine (0.8 mg/kg) administrated in WT and P-gp KO mice results in the plasma total concentrations 580 ng/mL and 467 ng/mL at 6 min after dosing, respectively, and the plasma protein binding with 41.1% and 45.9%. The absorption of [14C]Bepotastine from the proximal region in the presence and absence of verapamil is 63.0% and 72.4%, respectively, and that from the distal region is 10.9% and 62.7%, respectively. [2] Bepotastine besilate (10 mg/kg) inhibits scratching induced by an intradermal injection of histamine (100 nmol/site), but not serotonin (100 nmol/site). Bepotastine besilate (1 mg/kg-10 mg/kg, oral) dose-dependently suppresses scratching induced by substance P (100 nmol/site) and leukotriene B(4) (0.03 nmol/site). [3] Bepotastine besilate significantly inhibits conjunctival vascular hyperpermeability in a dose-dependent manner in guinea pig allergic conjunctivitis models with maximal effect for Bepotastine besilate 1.5%. [4] Bepotastine (3 mg/kg and 10 mg/kg) effectively inhibits the compound 48/80-induced scratching behavior of BALB/c mice 1 hour after oral administration. Bepotastine (10 mg/kg) also significantly inhibits the scratching behavior and suppresses the serum LTB(4) levels in atopic dermatitis model NC/Nga mice. [5] |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × 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).
Dilution Calculator
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.
