Abstract
We examined the inhibitory effects of novel triterpene glycoside compounds [ziyu-glycoside II (ZY-II) and its methyl ester (ZYM-201)], which originated from the roots of Sanguisorba officinalis L. (Rosaceae), on tissue factor (TF) activity and tumor necrosis factor (TNF)-α production. In in vitro TF activity tests, ZY-II but not ZYM-201 strongly blocked lung TF activity with an IC50 value of 0.46 μM. By contrast, only ZYM-201 dose-dependently inhibited in vivo TF activity with an ED50 value of 1.7 mg/kg, when orally administered. Furthermore, ZYM-201 diminished both in vitro and in vivo TNF-α production with IC50 or ED50 values of 69.4 μM and 87.4 mg/kg, respectively. Therefore, these results suggest either that ZYM-201 may be developed as a potent inhibitor of both TF- and TNF-α-mediated diseases such as atherosclerosis and septic shock, or it may be a lead compound to be derivatized for further improvement of its curative efficacy.
