Vitexin arginine is a natural c-glycosylated flavone isolated from various medicinal plants species,with anti-oxidant, anti-cancer, anti-inflammatory, anti-hyperalgesic, and neuroprotective effects.
L-hydroxy Arginine is a substrate for nitric oxide synthase in the catabolism of L-arginine to form nitric oxide. It has been used as a biomarker for reduced nitric oxide formation in patients with cardiovascular disease and metabolic syndrome.
Nω-Propyl-L-arginine, a powerful and specific inhibitor of neuronal nitric oxide synthase (nNOS), effectively inhibits nNOS with a Ki of 57 nM. It exhibits a remarkable 149-fold selectivity for nNOS over endothelial NOS (eNOS).
Nω-allyl-L-arginine is a competitive and reversible inhibitor of bovine brain nitric oxide synthase (nNOS), efficiently inactivating nNOS in a time-dependent manner. Additionally, Nω-allyl-L-arginine acts as a substrate, generating L-arginine, acrolein, and H2O.
L-Arginine-15N4 ((S)-(+)-Arginine-15N4) hydrochloride, the 15N-labeled variant of L-Arginine hydrochloride ((S)-(+)-Arginine hydrochloride), serves as the nitrogen donor in the synthesis of nitric oxide. This potent vasodilator is crucial, especially during a sickle cell crisis where its levels are notably diminished.
Perindopril arginine is an angiotensin converting enzyme inhibitor, and amlodipine, a dihydropyridine calcium channel blocker, and is indicated for the treatment of hypertension, to lower blood pressure.
