一般的な説明A highly potent and selective oxysterol EBI2 (GPR183) agonist (Kd) = 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.

純化方法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.]
