Oral administration of nicotinamide mononucleotide is safe and efficiently increases blood nicotinamide adenine dinucleotide levels in healthy subjects was written by Okabe, Keisuke;Yaku, Keisuke;Uchida, Yoshiaki;Fukamizu, Yuichiro;Sato, Toshiya;Sakurai, Takanobu;Tobe, Kazuyuki;Nakagawa, Takashi. And the article was included in Frontiers in Nutrition in 2022.Formula: C11H15N2O8P The following contents are mentioned in the article:

NMN (NNM) is an orally bioavailable NAD⁺ precursor that has demonstrated beneficial effects against aging and aging-associated diseases in animal models. NMN is ultimately converted to NAD⁺, a redox cofactor that mediates many metabolic enzymes. NAD⁺ also serves as the substrate for poly(ADP-ribose) polymerase (PARP) and sirtuins, and regulates various biol. processes, such as metabolism, DNA repair, gene expression, and stress responses. Previous mouse models showed that NMN administration can increase NAD⁺ in various organs and ameliorate agingrelated diseases, such as obesity, diabetes, heart failure, stroke, kidney failure, and Alzheimer′s disease through NAD⁺-mediated pathways. However, evidence of its effect on humans is still scarce. In this study, we conducted a placebo-controlled, randomized, double blind, parallel-group trial to investigate the safety of orally administered NMN and its efficacy to increase NAD⁺ levels in thirty healthy subjects. Healthy volunteers received 250 mg/day of NMN (n = 15) or placebo (n = 15) for 12 wk, and physiol. and laboratory tests were performed during this period. In addition, NAD⁺ and its related metabolites in whole blood were examined Oral supplementation of NMN for 12 wk caused no abnormalities in physiol. and laboratory tests, and no obvious adverse effects were observed NAD⁺ levels in whole blood were significantly increased after NMN administration. We also observed the significant rise in nicotinic acid mononucleotide (NAMN) levels, but not in NMN. We also found that the increased amount of NAD⁺ was strongly correlated with pulse rate before the administration of NMN. These results suggest that oral administration of NMN is a safe and practical strategy to boost NAD⁺ levels in humans. 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: 1094-61-7Formula: C11H15N2O8P).

((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. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Formula: C11H15N2O8P

((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. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Category: amides-buliding-blocks

Preconditioning of mesenchymal stem cells with ghrelin exerts superior cardioprotection in aged heart through boosting mitochondrial function and autophagy flux was written by Sun, Liqiang;Zhang, Wenlong. And the article was included in European Journal of Pharmacology in 2021.SDS of cas: 1094-61-7 The following contents are mentioned in the article:

Application of mesenchymal stem cells (MSCs) is considered as a promising cell-based therapy to induce cardioprotection against ischemia-reperfusion (IR) injury. Preconditioning of MSCs is the key strategy to improve MSCs functions in vitro and their efficacy in vivo, especially in elderly subjects in whom cardioprotection is lost. This study investigated the effects of preconditioning of human umbilical cord-derived MSCs with ghrelin and their combination with nicotinamide-mononucleotide (NMN) on cardioprotection, and the role of autophagy flux and mitochondrial function in aged hearts subjected to IR injury. Aged Sprague Dawley rats (20-22 mo old) were subjected to LAD occlusion-induced myocardial IR injury and treated with ghrelin-preconditioned or unconditioned-MSCs at early reperfusion. NMN (500 mg/kg, i.p) was also administered at early reperfusion and repeated 12 h later. Intra-myocardial injection of ghrelin-preconditioned MSCs reduced infarct size and cardiotroponin release of aged myocardium, and improved cardiac function following IR injury. MSCs preconditioning with ghrelin restored IR-induced mitochondrial reactive oxygen species and membrane potential depolarization and enhanced ATP production To reveal possible mechanism, preconditioned-MSCs increased autophagy flux by downregulating the overexpression of Beclin-1 and P62 proteins and increasing the LC3-II expression and LC3-II/LC3-I ratio. Moreover, combining NMN to ghrelin-preconditioned MSCs synergistically augmented its protective effects on infarct size and mitochondrial function. All above effects were abolished by autophagy flux inhibitor, chloroquine. Thus, ghrelin may serve as a promising candidate to improve the cardioprotective efficacy of MSC-based therapy via autophagy/mitochondrial pathway and that NMN serves as a good booster in combination therapy in aged hearts. 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: 1094-61-7SDS of cas: 1094-61-7).

((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. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.SDS of cas: 1094-61-7

Dihydronicotinamide riboside is a potent NAD+ precursor promoting a pro-inflammatory phenotype in macrophages was written by Chini, Claudia C.

NAD (NAD) metabolism plays an important role in the regulation of immune function. However, a complete picture of how NAD, its metabolites, precursors, and metabolizing enzymes work together in regulating immune function and inflammatory diseases is still not fully understood. Surprisingly, few studies have compared the effect of different forms of vitamin B3 on cellular functions. Therefore, we investigated the role of NAD boosting in the regulation of macrophage activation and function using different NAD precursors supplementation. We compared NMN (NMN), nicotinamide riboside (NR), and nicotinamide (NAM) supplementation, with the recently described potent NAD precursor NRH. Our results show that only NRH supplementation strongly increased NAD+ levels in both bone marrow-derived and THP-1 macrophages. Importantly, NRH supplementation activated a pro-inflammatory phenotype in resting macrophages, inducing gene expression of several cytokines, chemokines, and enzymes. NRH also potentiated the effect of lipopolysaccharide (LPS) on macrophage activation and cytokine gene expression, suggesting that potent NAD+ precursors can promote inflammation in macrophages. The effect of NRH in NAD+ boosting and gene expression was blocked by inhibitors of adenosine kinase, equilibrative nucleoside transporters (ENT), and IkB kinase (IKK). Interestingly, the IKK inhibitor, BMS-345541, blocked the mRNA expression of several enzymes and transporters involved in the NAD boosting effect of NRH, indicating that IKK is also a regulator of NAD metabolism In conclusion, NAD precursors such as NRH may be important tools to understand the role of NAD and NADH metabolism in the inflammatory process of other immune cells, and to reprogram immune cells to a pro-inflammatory phenotype, such as the M2 to M1 switch in macrophage reprogramming, in the cancer microenvironment.

The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine.

Nicotinic acid supplementation at a supraphysiological dose increases the bioavailability of nicotinamide adenine dinucleotide precursors in mares was written by Pollard, Charley-Lea;Gibb, Zamira;Swegen, Aleona;Lawson, Edwina F.;Grupen, Christopher G.. And the article was included in Journal of Animal Physiology and Animal Nutrition in 2021.Electric Literature of C11H15N2O8P The following contents are mentioned in the article:

NAD+ deficiency has recently been linked with increased occurrences of congenital abnormalities and embryonic death in human and animal subjects. Early embryonic death is a major component of pregnancy loss in mares and very little is known regarding the requirement for NAD+ in horses. The aim of this study was to quantify NAD+ and its metabolites in the plasma and urine of mares after orally administering an acute dose of nicotinic acid and determine the absorption, metabolism and excretion of this essential precursor for NAD+ biosynthesis. Nicotinic acid (5 g per os) was administered to four mares via a dosing syringe. Blood samples were collected at 0, 0.25, 0.5, 1, 2, 4, 6 and 22 h, and urine samples were collected at 0, 3, 6 and 22 h. The samples were processed and analyzed by mass spectrometry. A general additive model was applied to all metabolite concentration values followed by a post-hoc multiple comparisons test. Nicotinic acid was rapidly absorbed into peripheral blood within 15 min of administration and the concentrations of nicotinic acid, nicotinamide (NAM), nicotinuric acid, nicotinic acid mononucleotide and nicotinic acid adenine dinucleotide (NaAD) increased significantly in plasma at 30 min. The concentrations of NAM, nicotinic acid riboside and NaAD increased significantly in urine at 3 h. The levels of NAM and NaAD remained significantly elevated in plasma at 22 h, sixfold and ninefold greater, resp., than the basal levels at 0 h. While the extracellular levels of NAD+ in the samples remained undetected, the large, sustained elevation of NaAD levels in plasma indicates that the NAD+ levels were boosted within the cellular compartments. The results show that nicotinic acid supplementation increases the bioavailability of NAD+ precursors in mares, which is proposed to be beneficial during periods of peak NAD+ demand, such as during early embryo development. 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: 1094-61-7Electric Literature of C11H15N2O8P).

Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.Electric Literature of C11H15N2O8P

NADH and NRH as potential dietary supplements or pharmacological agents for early liver injury caused by acute alcohol exposure was written by Wu, Ke;Li, Jieqing;Zhou, Xuhan;Zhou, Fei;Tang, Shenzhen;Yi, long;Wu, Yong;Tian, Shiliu. And the article was included in Journal of Functional Foods in 2021.Application In Synthesis of ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate The following contents are mentioned in the article:

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.

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

NADH and NRH as potential dietary supplements or pharmacological agents for early liver injury caused by acute alcohol exposure was written by Wu, Ke;Li, Jieqing;Zhou, Xuhan;Zhou, Fei;Tang, Shenzhen;Yi, long;Wu, Yong;Tian, Shiliu. And the article was included in Journal of Functional Foods in 2021.Recommanded Product: 1094-61-7 The following contents are mentioned in the article:

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: 1094-61-7Recommanded Product: 1094-61-7).

((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. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Recommanded Product: 1094-61-7
