A steroidal saponin; inhibits HGF-induced invasive activity and COX-2 gene expression in MDA-MB-231 breast cancer cells and B16-F10 melanoma cells; reduces the number of metastatic nodules in B16-F10 melanoma cell-treated mice; reduces 2,3,4-trinitrobenzene sulfonic acid-induced colon shortening, myeloperoxidase activity, NF-kB activation, and IL-1β, TNF-α, and IL-6 levels in mice; reduces mortality and venous thrombus weight in mice with acute thromboembolism; inhibits AChE in vitro (IC50 = 35.4 μM)
