产品描述 Description

Nicotinamide riboside, a form of vitamin B3 and NAD+ precursor, is converted to bioavailable NAD+, via nicotinamide riboside kinase (NRK) and NMNAT, or by the action of nucleoside phosphorylase and NAM salvage^[1-2].

In in vitro experiments ,nicotinamide riboside attenuates alcohol induced liver injuries via activation of SirT1/PGC-1α/mitochondrial biosynthesis pathway ^[3]. Nicotinamide Riboside Enhances In Vitro Beta-adrenergic Brown Adipose Tissue Activity in Humans^[4].

Nicotinamide Riboside was able to enhance the skeletal muscle NAD+ metabolome, inducing gene expression signatures implicated in downregulation of energy metabolism pathways, but did not affect muscle mitochondrial bioenergetics or metabolism^[5]. Nicotinamide Riboside enhances deacetylase activity in vivo, deacetylates PGC-1α in muscle, liver, and BAT, and it induces deacetylase activity in tissues where NAD+ accumulates^[6].

实验参考方法 Experimental Reference Method

Cell experiment [1]:
Cell lines	Murine RAW 264.7 macrophages
Preparation Method	The prepared mouse bone marrow-derived macrophages were cultured and stored at 37°C in 5% CO2. Murine RAW 264.7 macrophages were treated with EtOH (80 mM), MeCHO (200 μM), and nicotinamide riboside (1 mM), respectively, and ROS accumulation was determined.
Reaction Conditions	1 mM ,72 h
Applications	Ethanol and its metabolite, acetaldehyde, significantly increased cellular ROS levels, but Nicotinamide riboside completely abolished the increase to a basal level in RAW 264.7 macrophages.
Animal experiment [2]:
Animal models	Eight-week-old male C57BL/6 J mice
Preparation Method	The reared mice were randomly divided into 3 groups: control group (CTRL), ethanol group (EtOH) and nicotinamide riboside supplementation group (EtOH+ Nicotinamide riboside ). Mice in the ethanol and nicotinamide riboside supplemented groups were fed a Lieber-DeCarli ethanol liquid diet, while control mice were paired as previously described.
Dosage form	400 mg/kg, oral gavage once daily for 10 consecutive days
Applications	Mice were fed in pairs and there was no difference in body weight between the three groups. Fat accumulation was observed in the ethanol group, while only a few tiny lipid droplets were observed in the nicotinamide riboside group. Nicotinamide riboside significantly decreased serum ALT and AST and liver triglyceride levels, and slightly decreased liver weight ratio.
