l-arginine

1. L-Arginine (L-Arg) exhibits anti-atherosclerotic effect. 2. L-Arginine and soy enriched diet are effective in prevention of osteoporosis associated with diabetes mellitus. 3. Exogenous L-Arginine could enhance neonate lymphocyte proliferation through an interleukin-2-independent pathway. 4. A combination of oral L-citrulline and L-Arginine effectively and rapidly augments NO-dependent responses at the acute stage.

N-Acetyl-L-arginine dihydrate (N-Ac-L-arg-OH) is one of the guanidino compounds found elevated in the serum of a hemodialyzed renal insufficient (uremic) pediatric population.

L-Arginine hydrochloride is a nitrogen donor for synthesis of nitric oxide.

N-Acetyl-L-arginine (Ac-Arg-OH) belongs to the class of organic compounds known as n-acyl-l-alpha-amino acids. These are n-acylated alpha amino acids which have the L-configuration of the alpha-carbon atom. N-a-Acetyl-L-arginine serum levels (and other guanidino compounds) were elevated of all the hyperargininemic patients are higher than the normal range. N-a-Acetyl-L-arginine is a very strong basic compound (based on its pKa). Untreated hyperargininemic patients have the highest guanidino compound levels in cerebrospinal fluid. N-a-Acetyl-L-arginine is one of the guanidino compounds found elevated in the serum of an hemodialyzed renal insufficient (uremic) pediatric population. Outside of the human body, N-a-Acetyl-L-arginine has been detected, but not quantified in, apples and loquats. This could make N-a-acetyl-L-arginine a potential biomarker for the consumption of these foods. N-a-Acetyl-L-arginine, with regard to humans, has been found to be associated with several diseases such as uremia and colorectal cancer; N-a-acetyl-L-arginine has also been linked to the inborn metabolic disorder hyperargininemia. During a low-arginine diet, together with sodium benzoate therapy, there was a marked decrease in plasma N-alpha-acetylarginine. N-a-Acetyl-L-arginine increases in urine hyperargininemic patients.

SDMA (Symmetric dimethylarginine) is the most potent endogenous inhibitor of nitric oxide synthase (NOS), with higher levels in patients with end-stage renal disease (ESRD).

Triptoquinone A may be a useful candidate for the development of a drug as a potent inhibitor of iNOS gene over-expression. Triptoquinone A has anti-inflammatory activity, it prevents ndotoxin-or interleukin-1 beta-promoted induction of nitric oxide synth

L-Lysine (Aminutrin) is one of nine essential amino acids in humans required for growth and tissue repair, Lysine is supplied by many foods, especially red meats, fish, and dairy products. Lysine seems to be active against herpes simplex viruses and present in many forms of diet supplements. The mechanism underlying this effect is based on the viral need for amino acid arginine; lysine competes with arginine for absorption and entry into cells. Lysine inhibits HSV growth by knocking out arginine.

L-Citrulline is an amino acid derived from ornithine in the catabolism of proline or glutamate and glutamine, or from l-arginine via arginine-citrulline pathway.

L-Aspartic acid (Aspatofort) is a non-essential amino acid in humans, L-Aspartic acid has an overall negative charge and plays an important role in the synthesis of other amino acids and in the citric acid and urea cycles. Asparagine, arginine, lysine, methionine, isoleucine, and some nucleotides are synthesized from aspartic acid. L-Aspartic acid also serves as a neurotransmitter.

4-Guanidinobutanoic acid (4-GBA) is an L-arginine metabolite that has been used in the intestinal transport tranport studies. It has been specifically use to human proton coupled amino acid transporters hPAT1.
