1. Ruscogenin has anti-inflammatory activity, suppressed zymosan A-evoked peritoneal total leukocyte migration in mice in a dose-dependent manner, 2. Ruscogenin inhibited adhesion of leukocytes to a human umbilical vein endothelial cell line (ECV34) injured by tumor necrosis factor-alpha (TNF-alpha) in a concentration-dependent manner. 3. Ruscogenin significantly attenuate LPS-induced acute lung injury via inhibiting expressions of TF and iNOS and NF-kappa B p65 activation.

Compound 1, (25R)-Ruscogenin-3-yl α-L-rhamnopyranosyl-(1→2)-[β-D-xylopyranosyl-(1→4)]-β-D-glucopyranoside, is a steroidal saponin that can be isolated from the roots of Ophiopogon japonicus [1].

(1beta,3beta,25S)-3-Hydroxyspirost-5-en-1-yl 2-O-(6-deoxy-alpha-L-mannopyranosyl)-beta-D-xylopyranoside is a natural product

25(R,S)-Ruscogenin is a natual product.

1. Neoruscogenin represents a universal pharmacological tool for RORα research due to its specific selectivity profile versus other nuclear receptors.
