Agmatine is a dicationic amine at physiological pH, formed by decarboxylation of arginine catalyzed by arginine decarboxylase. It acts on polyamine metabolism by inhibiting nitric oxyde synthase and activating spermidine/spermine acetyltransferase as well as the antizyme of ornithine decarboxylase. Agmatine is metabolized by agmatinase to form urea and putrescine, suggesting that it is a polyamine precursor. Agmatine is transported to organs by an energydependent mechanism, whereas increased cellular concentrations promotes apoptosis. Agmatine and its metabolic enzymes arginine decarboxylase and agmatinase have also been recognized in mitochondria, as well as imidazoline I2 receptor. These observations and the results obtained in these year...
