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.
