NO Synthase Activator

Isosorbide dinitrate (Standard) is the analytical standard of Isosorbide dinitrate. This product is intended for research and analytical applications. Isosorbide dinitrate (ISDN) is an NO donor that prevents LV remodeling and degradation of cardiac function following myocardial infarction (MI).

Quinolinic acid-¹³C₇ is the ¹³C labeled Quinolinic acid (HY-100807). Quinolinic acid, an endogenous metabolite of tryptophan, is a N-methyl-D-aspartate receptor (NMDA receptor) agonist. Quinolinic acid increases glutamate efflux, induces the generation of ROS, activates nitric oxide synthase, produces excessive NO, leading to calcium ion influx and neuronal apoptosis.

Piceatannol 3'-O-glucoside (Standard) is the analytical standard of Piceatannol 3'-O-glucoside. This product is intended for research and analytical applications. Piceatannol 3'-O-glucoside, an active component of Rhubarb, activates endothelial nitric oxide (NO) synthase through inhibition of arginase activity with IC₅₀s of 11.22 μM and 11.06 μM against arginase I and arginase II, respectively.

Quinocetone (Standard) is the analytical standard of Quinocetone (HY-123581). This product is used for research and analytical purposes. Quinocetone is an orally active animal feed additive used to increase the meat production of livestock and poultry. Quinocetone exhibits antibacterial activity against a variety of pathogenic microorganisms. Quinocetone exhibits tissue-specific (liver, lymphocyte) toxicity. Quinocetone induces autophagy in cells through the ATF6/DAPK1 pathway. Quinocetone activates the NF-κB and iNOS pathways, leading to cell apoptosis, hepatocyte vacuolar degeneration and fibrosis. Quinocetone can inhibit Nrf2/HO-1 and induce the generation of reactive oxygen species (ROS), leading to oxidative stress and DNA damage.

L-Arginine-¹⁵N₄,d₇ (hydrochloride) is the deuterium and ¹⁵N-labeled L-Arginine hydrochloride. L-Arginine hydrochloride ((S)-(+)-Arginine hydrochloride) is the nitrogen donor for synthesis of nitric oxide, a potent vasodilator that is deficient during times of sickle cell crisis.

Rosuvastatin lactone-d₆ is the deuterium labeled Rosuvastatin lactone. Rosuvastatin lactone is a metabolite of Rosuvastatin (HY-17504A), a statin lipid-lowering agent and HMG-CoA inhibitor. Rosuvastatin lactone exhibits endothelium-independent and HMG-CoA reductase-independent vasorelaxant activity in rat aortic rings, and its vasorelaxant effect is jointly mediated by NO produced by inducible nitric oxide synthase (iNOS) located in vascular smooth muscle and activation of potassium channels. Rosuvastatin lactone itself has no lipid-lowering effect.

NCX1022 is an NO-releasing derivative of Hydrocortisone, which is the most widely used anti-inflammatory agent for the treatment of skin inflammation.
