Berberine Chloride

A highly potent and selective oxysterol EBI2 (GPR183) agonist (K_d) = 450 pM in a saturation binding assay, and EC₅₀ = 140 pM over EC₅₀ = 2.1 nM for its enantiomer, 7β,25-OHC, in a GTP-γS binding assay).

Descrição

Descrição geral

A highly potent and selective oxysterol EBI2 (GPR183) agonist (K_d) = 450 pM in a saturation binding assay, and EC₅₀ = 140 pM over EC₅₀ = 2.1 nM for its enantiomer, 7β,25-OHC, in a GTP-γS binding assay). Dose-dependently suppresses forskolin-induced cAMP accumulation in an EBI2-expressing SK-N-MC/CRE-β-galactosidase cell line (IC₅₀ = 2 nM), but not in control cells. Stimulates migration of LPS-activated spleen B-cells and anti-CD3/CD28-activated CD4⁺ T-cells in a dose-dependent manner. In addition, pharmacological inhibition of its biosynthesis in vivo by Clotrimazole, a CYP7B1inhibitor, promotes the migration of adoptively transferred pre-activated B cells to the T/B boundary, mimicking the phenotype of pre-activated B cells in EBI2-deficient mice.

Aplicação

Fluorescent stain for heparin in mast cells

Ações bioquímicas/fisiológicas

An alkaloid with weak antibiotic properties. Substrate for MDR efflux pumps. Antimicrobial activities of berberine is potentiated by the MDR inhibitor 5´-methoxyhydnocarpin (5´-MHC). Berberine upregulates the expression of Pgp in hepatoma cells. Treatment with berberine potentially results in the reduced accumulation of chemotherapeutic drugs.
