NG,NG-dimethyl-L-Arginine (hydrochloride)

NG,NG-dimethyl-L-arginine (ADMA) is an endogenous inhibitor of nitric oxide synthase (NOS).{52984,3249} It is formed from arginine by protein arginine methyltransferases (PRMTs) and degraded by dimethylarginine dimethylaminohydrolases (DDAHs) and alanine-glyoxylate aminotransferase 2 (AGXT2).{52984} ADMA levels are increased concomitant with an increase in blood pressure in Dahl salt-sensitive rats fed a high-salt diet.{3249} ADMA levels are increased in the plasma in a variety of endothelial dysfunction-related diseases, including hypertension, congestive heart failure, and end-stage renal disease.{52984,822,4517}
