Betamethasone dipropionate, the prodrug of Betamethasone, is an orally active and potent glucocorticoid with anti-inflammatory and immunosuppressive activity. Betamethasone appears to be an effective inhibitor of LPS-induced inflammation and MMP release.
体外研究
The Calcipotriol/Betamethasone combination significantly inhibits the secretion of IL-17A and TNF-α in psoriatic skin. Additionally, the two components show additive inhibitory effects on secretion of IL-23 and TNF-α by DCs, of IL-17A and TNF-α by both CD4+ and CD8+ T cells and reduced inflammatory responses in Th17-stimulated keratinocytes.
RT-PCR
Cell Line:
Pig and human skin.
Concentration:
1 μM.
Incubation Time:
24 h.
Result:
Additively inhibit expression of inflammatory cytokines in psoriasis skin explant cultures.
Affected the activity of DCs resulting in a decreased secretion of TNF-α and IL-23.
体内研究
Betamethasone (5 mg/kg, orally) reduces the LPS-induced pulmonary inflammation and production of MMPs.
Animal Model:
Ten-week-old male Balb/c mice.
Dosage:
5 mg/kg (100 μg/ml for 60 min).
Administration:
Orally at 24 h and 1 h before the LPS aerosol.
Result:
Significantly (P < 0.05) inhibited the decrease of IL-10 level in BAL fluid induced by LPS exposure.
Markedly reduced the release of both MMP-2 and MMP-9.
