Catalposide, an iridoid glycoside that could be isolated from Catalpa ovate G. Don (Bignoniaceae), inhibits TNF-α, IL-1β, and IL-6 productions and NF-κB (p65) activation in lipopolysaccharide-activated RAW 264.7 macrophages[1].
Catalposide (1-1000 ng/mL) could inhibit TNF-a, IL-1β, and IL-6 productions in RAW 264.7 macrophages[1].
