Properties Suppliers
Naringenin

Naringenin is a flavanone, a type of flavonoid, that is considered to have a bioactive effect on human health as antioxidant, free radical scavenger, anti-inflammatory, carbohydrate metabolism promoter, and immune system modulator. It is the predominant flavanone in grapefruit.

Properties Suppliers
Natamycin

Natamycin is a naturally occurring antifungal agent produced during fermentation by the bacterium Streptomyces natalensis, commonly found in soil. Natamycin has a very low solubility in water, due to the amphiphilic nature of the molecule. However, natamycin is effective at very low levels. Natamycin is classified as a macrolide polyene antifungal and, as a drug, is used to treat fungal keratitis. It is especially effective against Aspergillus and Fusarium corneal infections.

Properties Suppliers
Nateglinide

Nateglinide is a drug for the treatment of type 2 diabetes.Nateglinide belongs to the meglitinide class of blood glucose-lowering drugs. Nateglinide lowers blood glucose by stimulating the release of insulin from the pancreas. It achieves this by closing ATP-dependent potassium channels in the membrane of the β cells. This depolarizes the β cells and causes voltage-gated calcium channels to open. The resulting calcium influx induces fusion of insulin-containing vesicles with the cell membrane, and insulin secretion occurs.

Properties Suppliers
Nebivolol

Nebivolol is a β1 receptor blocker with nitric oxide-potentiating vasodilatory effect used in treatment of hypertension and, in Europe, also for left ventricular failure.It is highly cardioselective under certain circumstances.Nebivolol lowers blood pressure (BP) by reducing peripheral vascular resistance, and significantly increases stroke volume with preservation of cardiac output.

Properties Suppliers
Nebivolol Hydrochloride

Nebivolol Hydrochloride acts as a selective β1-adrenoceptor antagonist.Induces vasodilation via a nitric oxide- and cGMP-dependent mechanism and displays antihypertensive activity.
