Background:

N^G,N^G-dimethyl-L-arginine-d₆(ADMA-d₆) (hydrochloride) is intended for use as an internal standard for the quantification of N^G,N^G-dimethyl-L-arginine by GC- or LC-MS. ADMA is an endogenous inhibitor of nitric oxide synthase (NOS).^1,2It is formed from arginine by protein arginine methyltransferases (PRMTs) and degraded by dimethylarginine dimethylaminohydrolases (DDAHs) and alanine-glyoxylate aminotransferase 2 (AGXT2).¹ADMA levels are increased concomitant with an increase in blood pressure in Dahl salt-sensitive rats fed a high-salt diet.²ADMA levels are increased in the plasma in a variety of endothelial dysfunction-related diseases, including hypertension, congestive heart failure, and end-stage renal disease.^1,3,4
