Allgemeine Beschreibung
A highly potent and selective oxysterol EBI2 (GPR183) agonist (K
d) = 450 pM in a saturation binding assay, and EC
50 = 140 pM over EC
50 = 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 (IC
50 = 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.
Sicherheitsprofil
Poison by intraperitoneal route.Slightly toxic by ingestion. Mutation data reported. Whenheated to decomposition it emits toxic vapors of NOx andCl-.
läuterung methode
Berberine chloride crystallises from water to give the dihydrate. The anhydrous salt may be obtained by recrystallisation from EtOH/Et2O, wash the crystals with Et2O and dry them in a vacuum. The iodide has m 250o(dec) (from EtOH). [Perkin J Chem Soc 113 503 1918, Kametani et al. J Chem Soc(C) 2036 1969, Beilstein 27 I 515, 27 II 567.]
Clinical claims and research
People most commonly use berberine for diabetes, high levels of cholesterol or other fats in the blood, and high blood pressure. It is also used for burns, canker sores, liver disease, and many other conditions but there is no good scientific evidence to support many of these uses.
