Verproside

Verproside, a catalpol derivative iridoid glycoside isolated from the genus Pseudolysimachion, represses TNF-α -induced MUC5AC expression by inhibiting NF-κB activation via the IKK/IκB signaling cascade. Verproside has potent anti-inflammatory, antioxidant, antinociceptive activities and ir is a potent anti-asthmatic/COPD drug candidate in vivo[1]. NF-κB TNF-α IKK

Verproside (2.5-20 μM; for 2 hours) markedly reduces phosphorylation levels of IKKα/β, IκBα, and TAK1 in the 5-20 μM range[1]. Western Blot Analysis[1] Cell Line: NCI-H292 cells

Verproside (Intragastrically; 30 mg/kg; 48 hours) significantly reduces the immunoglobulin E (IgE) levels of verproside-treated mice[2]. Animal Model: Specific pathogen-free female BALB/c mice aged 8-10 weeks[2]
