7α,25-Dihydroxycholesterol (Synonyms:7α,25-OHC)
目录号 : KM9908 CAS No. : 64907-22-8 纯度 : ≥98%

7α, 25-dihydroxycholesterol (7α,25-OHC) 是一种孤儿 GPCR 受体 EBI2 (GPR183) 的有效选择性激动剂和内源性配体。7α, 25-dihydroxycholesterol 对激活 EBI2 有很强的作用 (EC50=140 pM; Kd=450 pM)。7α, 25-dihydroxycholesterol 可作为一种趋化因子,指导 B 细胞、T 细胞和树突状细胞的迁移。

生物活性

7α, 25-dihydroxycholesterol (7α,25-OHC) is a potent and selective agonist and endogenous ligand of the orphan GPCR receptor EBI2 (GPR183). 7α, 25-dihydroxycholesterol is highly potent at activating EBI2 (EC50=140 pM; Kd=450 pM). 7α, 25-dihydroxycholesterol can serve as a chemokine directing migration of B cells, T cells and dendritic cells.

体外研究

In vitro, 7α, 25-dihydroxycholesterol (7α,25-OHC) stimulates the migration of EBI2-expressing mouse B and T cells with half-maximum effective concentration values around 500 pM, but had no effect on EBI2-deficient cells.

体内研究

EBI2-deficient B cells or normal B cells desensitized by 7α,25-Dihydroxycholesterol (1 μM; 1.5 hours) pre-treatment shows reduced homing to follicular areas of the spleen.

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
