Description:

Chikusetsusaponin IVa is a novel AMPK activator, can induce insulin secretion from βTC3 cells via GPR40 mediated calcium and PKC pathways, may be developed into a new potential for therapeutic agent used in T2DM patients.Chikusetsusaponin IVa exerts antithrombotic effects, including minor hemorrhagic events.

Chikusetsusaponin IVa methyl ester induces cell cycle arrest by the inhibition of nuclear translocation of β-catenin in HCT116 cells.   

We demonstrate that Chikusetsusaponin IVa methyl ester (CME), a triterpenoid saponin from the root of Achyranthes japonica, has an anticancer activity. 

METHODS AND RESULTS:

We investigate its molecular mechanism in depth in HCT116 cells. CME reduces the amount of β-catenin in nucleus and inhibits the binding of β-catenin to specific DNA sequences (TCF binding elements, TBE) in target gene promoters. Thus, CME appears to decrease the expression of cell cycle regulatory proteins such as Cyclin D1, as a representative target for β-catenin, as well as CDK2 and CDK4. As a result of the decrease of the cell cycle regulatory proteins, CME inhibits cell proliferation by arresting the cell cycle at the G0/G1 phase. 

CONCLUSIONS:

Therefore, we suggest that CME as a novel Wnt/β-catenin inhibitor can be a putative agent for the treatment of colorectal cancers.

Antithrombotic effect of chikusetsusaponin IVa isolated from Ilex paraguariensis (Maté).   

The triterpene Chikusetsusaponin IVa was isolated from the fruit of Ilex paraguariensis. 

METHODS AND RESULTS:

Using biochemical and pharmacological methods, we demonstrated that Chikusetsusaponin IVa (1) prolongs the recalcification time, prothrombin time, activated partial thromboplastin time, and thrombin time of normal human plasma in a dose-dependent manner, (2) inhibits the amidolytic activity of thrombin and factor Xa upon synthetic substrates S2238 and S2222, (3) inhibits thrombin-induced fibrinogen clotting (50% inhibition concentration, 199.4 ± 9.1 μM), and (4) inhibits thrombin- and collagen-induced platelet aggregation. The results also indicate that Chikusetsusaponin IVa preferentially inhibits thrombin in a competitive manner (K(i)=219.6 μM). Furthermore, when administered intravenously to rats, Chikusetsusaponin IVa inhibited thrombus formation in a stasis model of venous thrombosis, although it did not induce a significant bleeding effect. Chikusetsusaponin IVa also prolonged the ex vivo activated partial thromboplastin time. 

CONCLUSIONS:

Altogether, these data suggest that Chikusetsusaponin IVa exerts antithrombotic effects, including minor hemorrhagic events. This appears to be important for the development of new therapeutic agents.
