Description

Agmatine sulfate exerts modulatory action at multiple molecular targets, such as neurotransmitter systems, ion channels and nitric oxide synthesis. It is an endogenous agonist at imidazoline receptor and a NO synthase inhibitor.

IC50 & Target

Human Endogenous Metabolite

 

In Vitro

Agmatine binds to alpha 2-adrenergic and imidazoline receptors and stimulates release of catecholamines from adrenal chromaffin cells. Its biosynthetic enzyme, arginine decarboxylase, is present in brain. Agmatine, locally synthesized, is an endogenous agonist at imidazoline receptors, a noncatecholamine ligand at alpha 2-adrenergic receptors and may act as a neurotransmitter[1]. Agmatine is synthesized in the brain, stored in synaptic vesicles in regionally selective neurons, accumulated by uptake, released by depolarization, and inactivated by agmatinase. Agmatine inhibits nitric oxide synthase, and induces the release of some peptide hormones[2]. Agmatine, 4-(aminobutyl)guanidine, is produced by decarboxylation of L-arginine by the enzyme arginine decarboxylase. Agmatine is a competitive inhibitor of all NOS isoenzymes but not an NO precursor. Ki values are approximately 660 μM (NOS I), 220 μM (NOS II) and 7.5 mM (NOS III)[3]. Agmatine stimulates nitrite production three-fold above basal nitrite formation by endothelial cells. Agmatine displaces [3H]-idazoxan from endothelial cellmembranes and is found to induce transients in the cytosolic calcium of endothelial cells. The transients could be downregulated by repeated exposure to agmatine but are not affected by pretreatment with norepinephrine[4].

In Vivo

Agmatine produces an antidepressant-like effect when assessed in the forced swimming test and in the tail suspension test in mice (dose range 0.01-50 mg/kg, i.p.), without accompanying changes in ambulation in an open-field[5]. In ischemic stroke, agmatine protects the blood-brain barrier, which can be monitored in vivo by quantification of permeability by using dynamic contrast-enhanced MR imaging[6]. Agmatine substantially augments the antidepressant-like effect of MK-801, reinforcing the notion that this compound modulates NMDA receptor activation[7].

Animal Administration
[6][7]

Rats: Thirty-four male Sprague-Dawley rats are subjected to transient MCA occlusion for 90 minutes. Immediately after reperfusion, agmatine (100 mg/kg) or normal saline is injected intraperitoneally into the agmatine-treated group (n= 17) or the control group, respectively. MR imaging is performed after reperfusion[6].

Mice: Mice are pretreated with a range of sub-effective doses of either fluoxetine (1, 2.5 and 5 mg/kg, p.o.; a selective serotonin reuptake inhibitor), imipramine (0.01, 0.05 and 0.1 mg/kg, p.o.; a tricyclic antidepressant), bupropion (0.1, 0.5 and 1 mg/kg, p.o.; dopamine reuptake inhibitor with subtle activity on noradrenergic reuptake), or MK-801 (0.0001, 0.0005 and 0.001 mg/kg, p.o.; noncompetitive NMDA receptor antagonist) and immediately after, a sub-effective dose of either agmatine (0.0001 mg/kg p.o.) or vehicle is administered. After 60 min, the animals are subjected to behavioral testing[7].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
