ng,ng-dimethyl-l-arginine

NG,NG-dimethyl-L-Arginine dihydrochloride 是一种内源性一氧化氮合酶抑制剂。由 L-精氨酸合成的一氧化氮 (NO) 有助于调节血压和宿主防御。

SDMA (Symmetric dimethylarginine) 是一氧化氮 (NO) 合酶的内源性抑制剂。

SDMAp-hydroxyazobenzene-p′-sulfonate 是 SDMA 的对羟基偶氮苯-p′-磺酸盐衍生物，作为内源性一氧化氮合酶 (NO synthase) 的阻断剂。它也是 NF-κB 的激活剂，能够加强 IL-6 和 TNF-α 的表达。在血清和血浆中稳定，该化合物可以作为肝肾功能障碍的生物标志物使用。

NG,NG-dimethyl-L-arginine-d6 (ADMA-d6) (hydrochloride) is intended for use as an internal standard for the quantification of NG,NG-dimethyl-L-arginine by GC- or LC-MS. ADMA is an endogenous inhibitor of nitric oxide synthase (NOS). It is formed from arginine by protein arginine methyltransferases (PRMTs) and degraded by dimethylarginine dimethylaminohydrolases (DDAHs) and alanine-glyoxylate aminotransferase 2 (AGXT2). ADMA levels are increased concomitant with an increase in blood pressure in Dahl salt-sensitive rats fed a high-salt diet. 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.
