Biological Activity

Description Higenamine (Norcoclaurine, (+-)-Demethylcoclaurine), also known as Norcoclaurine HCl, is a non-selective β2 adrenoceptor agonist which is a chemical compound naturally occurring in a number of plants.
β2-adrenoceptor [1]
α1-adrenoceptor [1]
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[1]. 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[2].

In vivo Higenamine can produce relaxation in tracheal muscle[1]. 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[3].

Protocol (from reference)

Cell Research:


  • Cell lines: PC12 cells
  • Concentrations: 5-20 μM
  • Incubation Time: 12-48 h
  • Method:

    PC12 cells are maintained routinely in RPMI 1640 medium supplemented with 10% heat-inactivated horse serum and 5 % fetal calf serum pius 100 units/ml penicillin and 100 μg/ml streptomycin at 37°C. The PC12 cells (ca. 1×105 cells/cm2) are treated with higenamine (5-2O μM) and then incubated for 12 (-48) h. The cells (ca. 1.5-2 × 105 cells/cm2) are harvested with phosphate buffered saline (PBS) and the pellet extract is used for the measurement of dopamine content, and TH and AADC activities.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
