Asymmetric dimethylarginine

(2S)-2-amino-5-[(E)-[amino(dimethylamino)methylidene]amino]pentanoic acid

C8H18N4O2 (202.1429688)


Asymmetric dimethylarginine (ADMA) is a naturally occurring chemical found in blood plasma. It is a metabolic by-product of continual protein modification processes in the cytoplasm of all human cells. It is closely related to L-arginine, a conditionally-essential amino acid. ADMA interferes with L-arginine in the production of nitric oxide, a key chemical to endothelial and hence cardiovascular health. Asymmetric dimethylarginine is created in protein methylation, a common mechanism of post-translational protein modification. This reaction is catalyzed by an enzyme set called S-adenosylmethionine protein N-methyltransferases (protein methylases I and II). The methyl groups transferred to create ADMA are derived from the methyl group donor S-adenosylmethionine, an intermediate in the metabolism of homocysteine. (Homocysteine is an important blood chemical, because it is also a marker of cardiovascular disease). After synthesis, ADMA migrates into the extracellular space and thence into blood plasma. Asymmetric dimethylarginine is measured using high performance liquid chromatography. ADMA has been identified as a uremic toxin according to the European Uremic Toxin Working Group (PMID: 22626821). Isolated from broad bean seeds (Vicia faba). NG,NG-Dimethyl-L-arginine is found in many foods, some of which are yellow wax bean, spinach, green zucchini, and white cabbage. D004791 - Enzyme Inhibitors Asymmetric dimethylarginine is an endogenous inhibitor of nitric oxide synthase (NOS), and functions as a marker of endothelial dysfunction in a number of pathological states.

Symmetric dimethylarginine

(2S)-2-amino-5-[(E)-N,N-dimethylcarbamimidamido]pentanoic acid

C8H18N4O2 (202.1429688)


Symmetric dimethylarginine, also known as N,n-dimethylarginine or SDMA, is a L-arginine derivative having two methyl groups at the N(omega)- and N(omega)-positions It has a role as an EC 1.14.13.39 (nitric oxide synthase) inhibitor. It is a member of guanidines, a non-proteinogenic L-alpha-amino acid, a L-arginine derivative and a dimethylarginine. It is a tautomer of a N(omega),N(omega)-dimethyl-L-arginine zwitterion. It belongs to the class of organic compounds known as arginine and derivatives. Arginine and derivatives are compounds containing arginine or a derivative thereof resulting from reaction of arginine at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Symmetric dimethylarginine is a drug. Outside of the human body, symmetric dimethylarginine has been detected, but not quantified in pulses. Symmetric dimethylarginine (SDMA) is an endogenously produced inhibitor of nitric oxide synthase (EC-Number 1.14.13.39). However, elevated levels of Symmetric dimethylarginine occur in patients with vascular disease, especially suffering end-stage renal disease. Isolated from broad bean (Vicia faba) seed proteins SDMA (Symmetric dimethylarginine) is an endogenous inhibitor of nitric oxide (NO) synthase activity. SDMA, a novel kidney biomarker, permits earlier diagnosis of kidney disease than traditional creatinine testing.
