Product Description
Information
Higenamine (Norcoclaurine, (+-)-Demethylcoclaurine), also known as Norcoclaurine HCl, is a non-selectiveβ2 adrenoceptoragonist which is a chemical compound naturally occurring in a number of plants.
Targets
β2-adrenoceptor ; α1-adrenoceptor
In vitro
Higenamine is a potential β2-adrenoceptor agonist. As a potent cardiotonic and vasodilator, It is also an α1 antagonist and a weak α2 agonist. Higenamine decreases the intracellular dopamine content dose-dependently and shows 55.2% inhibition of dopamine content in PC12 cells at a concentration of 2OM with 24h incubation. The IC50 value of higenamine for inhibiting dopamine biosynthesis in PC12 cells is 18.2 μM. Dopamine content is lowered and reaches minimal level at 12—24h after exposure to higenamine.
In vivo
Higenamine can produce relaxation in tracheal muscle. Higenamine has anti-thrombotic effects in both mouse acute thrombosis model and rat arterio-venous shunt (AV-shunt) models. The oral administration of higenamine (50 or 100 mg/kg) increases the recovery rates from the acute thrombotic challenge in mice and lowers the weight of thrombus formed inside the AV-shunt tube in rats.
This compound belongs to the class of organic compounds known as benzylisoquinolines. These are organic compounds containing an isoquinoline to which a benzyl group is attached.
