Stachydrine (Proline betaine, L-stachydrine, Methyl hygrate betaine) is a quaternary ammonium derivative of proline that occurs widely in Medicago species. It is an osmoprotective compound found in urine. This compound is a major constituent of Chinese herb leonurus heterophyllus sweet used to promote blood circulation and dispel blood stasis. It can inhibit the NF-κB signal pathway.

Mechanism of Action

Targets/IC₅₀/Ki	NF-κB
In vitro	Stachydrine inhibits cell proliferation and induces primary apoptosis and ROS production in T47D and MCF-7 cells in time- and dose-dependent manner. Its treatment induces caspase-3 activation and decreases the expression of the anti-apoptotic protein Bcl-2. This compound simultaneously inhibits the phosphorylation of Akt and ERK proteins. It ameliorates the detrimental effect of high-glucose on EC (endothelial cells) and that its beneficial effect occurs through the modulation of cell senescence signaling and SIRT1 expression. This chemical inhibits AngII-induced excessive autophagy within H9c2 cells. It blocks the over phosphorylation of the p47phox subunit, decreases the translocation of p47phox and p67phox to the membrane, inhibits the activity of NOX2, and reduces the generation of ROS.
In vivo	Stachydrine ameliorates transverse aortic constriction (TAC)-induced cardiac hypertrophy, dysfunction and excessive autophagy in vivo. It shows significantly pharmacological properties including low toxicity, anti-inflammatory activities by improving the cellular membrane permeability, decreasing the levels of inflammatory factors and reducing the lipid peroxidation, and anti-oxidant activities by reducing plasma LDH activity and MDA levels, and protection against myocardial ischemia reperfusion injury in rats. The mean pharmacokinetic parameters of this compound after oral administration of Herba Leonuri extract: Tmax=0.75 h, t1/2z=1.64 h.
