How to use

In Vitro:

Toddalolactone inhibits the binding between PAI-1 and uPA, and therefore prevented the formation of the PAI-1/uPA complex.

In Vivo:

Intraperitoneal injection of toddalolactone in mice significantly prolonged tail bleeding and reduced arterial thrombus weight in a FeCl3-induced thrombosis model. Moreover, the hydroxyproline level in the plasma and the degree of liver fibrosis in mice were decreased after intraperitoneal injection of toddalolactone in CCl4-induced mouse liver fibrosis model.
