生物活性
Beclomethasone 17-propionate (Beclomethasone-17-monopropionate) 是 Beclomethasone dipropionate (HY-13571) 的活性代謝產(chǎn)物，是糖皮質(zhì)激素受體 (GR) 激動(dòng)劑。Beclomethasone 17-propionate 對(duì) GR 的親和力比 Beclomethasone dipropionate 高。Beclomethasone 17-propionate 有效抑制慢性阻塞性肺疾病 (COPD) 肺巨噬細(xì)胞中細(xì)胞因子的產(chǎn)生。體外研究
Metabolism of Beclomethasone dipropionate to 17-BMP is an important activation step. Beclomethasone 17-propionate inhibits LPS-stimulated CXCL8, TNFα and IL-6. The EC 50 values of Beclomethasone 17-propionate for IL-6, TNFα and CXCL8 were 0.05 nM, 0.01 nM and 0.1 nM, respectively. Beclomethasone 17-propionate evokes upregulation of the GR dependent genes FKBP51 and GILZ.
