Alcoholism leads to many diseases, and it is also the social and economic burden of the society. Alc. intake is the main cause of acute liver injury and chronic liver disease. Here, the ameliorative effect of NADH and dihydronicotinamide riboside (NRH) against alc.-induced liver damage was studied and its possible mechanism was further clarified. In vitro studies showed that NADH and NRH are effective NAD+ concentration-enhancing agents. Compared with NMN, NADH and NRH can provide greater NAD+ increase at the same concentrations I.p. injection of NADH and NRH in C57BL/6J mice also significantly increased the NAD+ content in liver, blood, brain, fat and kidney. Importantly, NADH and NRH significantly increased the liver NAD+/NADH ratio, but did not induce apoptosis markers in cells. The intragastric administration of 500 mg/kg NRH, 500 mg/kg NADH 15 min prior to acute alc. ingestion (8 mL/kg, 40% w/v, in tap water) could dramatically enhance alc. metabolism as revealed by the reduced concentrations of ethanol and acetaldehyde in blood as well as the decreased duration of the loss of righting reflex (LORR). Both Pretreatment and posttreatment with NADH or NRH could significantly reduce the increase of serum aspartate transaminase (AST) and alanine transaminase (ALT) after alc. administration, indicating that they have a certain therapeutic effect on alc. hepatotoxicity besides preventing the adverse effects caused by alc. NADH and NRH could also alleviate lipid peroxidation as indicated by the repressed malondialdehyde (MDA) level and the elevated activities of superoxide dismutase (SOD) in liver tissues. Addnl., NADH or NRH can mitigate the abnormal lipid metabolism in acute alc. liver damage. These benefits obviously suggested that NADH or NRH could be a potential nutraceutical or pharmacol. agent for promoting alc. metabolism and preventing or treating early liver injury caused by acute alc. exposure. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Application In Synthesis of ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate).
((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Application In Synthesis of ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate
