The main methods of NMNH powder preparation include extraction, fermentation, fortification, biosynthesis and organic matter synthesis. Compared with other preparations, the whole enzyme become the mainstream method owing to the advantages of pollution free, high level of purity and stability.
when applied to cultured cells, the NMNH is shown to be more efficient than NMN as it was able to “significantly increase NAD+ at a ten times lower concentration (5 µM) than that needed for NMN”. Moreover, NMNH shows to be more effective, as at 500 µM concentration, it achieved “an almost 10- fold increase in the NAD+ concentration, while NMN was only able to double NAD+ content in these cells, even at 1 mM concentration.”.
Interestingly, NMNH also appears to act quicker and has a longer-lasting effect compared to NMN. According to the authors, NMNH induces a “significant increase in NAD+ levels within 15 minutes”, and “NAD+ steadily increased for up to 6 hours and remained stable for 24 hours, while NMN reached its plateau after only 1 hour, most likely because the NMN recycling pathways to NAD+ had already become saturated.”.
NMNH also proved more effective than NMN in raising NAD+ levels in a variety of tissues when administered at the same concentration, confirming the results observed in cell lines. The data presented in this study also corroborate the evidence that NAD+ boosters protect against different models of acute kidney injury, and place NMNH as a great alternative intervention to other NAD+ precursors to reduce tubular damage and accelerate recovery.
To overcome the limitations of the current repertoire of NAD+ enhancers, other molecules with a more pronounced effect on the NAD+ intracellular pool are desired. This has stimulated us to investigate the use of the reduced form of nicotinamide mononucleotide (NMNH) as an NAD+ enhancer. There is very scarce information about the role of this molecule in cells. In fact, only one enzymatic activity has been described to produce NMNH. This is the NADH diphosphatase activity of the human peroxisomal Nudix hydrolase hNUDT1232 and the murine mitochondrial Nudt13.33 It has been postulated that, in cells, NMNH would be converted to NADH via nicotinamide mononucleotide adenylyl transferases (NMNATs).34 However, both NMNH production by Nudix diphosphatases and its use by NMNATs for NADH synthesis have only been described in vitro using isolated proteins, and how NMNH participates in cellular NAD+ metabolism remains unknown.
First, inspect the factory. After some screening, NMNH companies that directly face consumers pay more attention to brand building. Therefore, for a good brand, quality is the most important thing, and the first thing to control the quality of raw materials is to inspect the factory. Bontac company actually manufacturing NMNH powder of high quality with the caterias of SGS. Secondly, the purity is tested. Purity is one of the most important parameters of NMN powder. If high purity NMNH cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NMNH powder produced by Bontac reach the purity of 99%. Finally, a professional test spectrum is needed to prove it. Common methods for determining the structure of an organic compound include Nuclear Magnetic Resonance Spectroscopy (NMR) and high-resolution mass spectrometry (HRMS). Usually through the analysis of these two spectra, the structure of the compound can be preliminarily determined.
On August 10, 2021, researchers from Shanghai University of Science and Technology published an article titled NAD+ supplement potentiates tumor killing function by rescuing defective TUBBY-mediated NAMPT transcription in tumor infiltrated T cells in Cell Reports, revealing that NAD+ in supplemented during CAR-T therapy and immune checkpoint inhibitor therapy, it can improve the anti-tumor activity of T. At present, the supplementary precursor of NAD+, as a nutritional product,has been verified for human consumption safety.This achievement provides a simply and feasible new method for improving the anti-tumor activity of T cells. Cancer immunotherapies including the adoptive transfer of naturally occurring tumor-infiltrating lymphocytes (TILs) and genetically engineered T cells, as well as the use of immune checkpoint blockade (ICB) to boost the function of T cells, have emerged as promising approaches to achieve durable clinical responses of otherwise treatment-refractory cancers (Lee et al., 2015; Rosenberg and Restifo, 2015; Sharma and Allison, 2015). Although immunotherapies have been successfully used in the clinic, the number of patients benefiting from them is still limited (Fradet et al., 2019; Newick et al., 2017). Tumor microenvironment (TME)-related immunosuppression has emerged as the major reason for low and/or no response to both immunotherapies (Ninomiya et al., 2015; Schoenfeld and Hellmann, 2020). Therefore, efforts to investigate and overcome TME-related limitations in immune therapies are of great urgency. The fact that immune cells and cancer cells share many fundamental metabolic pathways implies an irreconcilable competition for nutrients in TME (Andrejeva and Rathmell, 2017; Chang et al., 2015). During uncontrolled proliferation, cancer cells hijack alternative pathways for more rapid metabolite generation (Vander Heiden et al., 2009). As a consequence, nutrient depletion, hypoxia, acidity, and generation of metabolites that can be toxic in the TME may hinder successful immunotherapy (Weinberg et al., 2010). Indeed, TILs often experience mitochondrial stress within growing tumors and become exhausted (Scharping et al., 2016). Interestingly, multiple studies also indicate that metabolic changes in TME could re-shape T cell differentiation and functional activity (Bailis et al., 2019; Chang et al., 2013; Peng et al., 2016). All these evidences inspired us to hypothesize that metabolic reprogramming in T cells might rescue them from a stressed metabolic environment, thereby reinvigorating their anti-tumor activity (Buck et al., 2016; Zhang et al., 2017). In this current study, by integrating both genetic and chemical screens, we identified that NAMPT, a key gene involved in NAD+ biosynthesis, was essential for T cell activation. NAMPT inhibition led to robust NAD+ decline in T cells, thereby disrupting glycolysis regulation and mitochondrial function, blocking ATP synthesis, and dampening the T cell receptor (TCR) downstream signaling cascade. Building on the observation that TILs have relatively lower NAD+ and NAMPT expression levels than T cells from peripheral blood mononuclear cells (PBMCs) in ovarian cancer patients, we performed genetic screening in T cells and identified that Tubby (TUB) is a transcription factor for NAMPT. Finally, we applied this basic knowledge in the (pre) clinic and showed very strong evidence that supplementation with NAD+ dramatically improves the anti-tumor killing activity both in adoptively transferred CAR-T cells therapy and immune check point blockade therapy, indicating their promising potential for targeting NAD+ metabolism to better treat cancers. 1.NAD+ regulates the activation of T cells by affecting energy metabolism After antigen stimulation, T cells undergo metabolic reprogramming, from mitochondrial oxidation to glycolysis as the main source of ATP. While maintaining sufficient mitochondrial functions to support cell proliferation and effector functions.Given that NAD+ is the main coenzyme for redox, the researchers verified the effect of NAD+ on the level of metabolism in T cells through experiments such as metabolic mass spectrometry and isotope labeling. The results of in vitro experiments show that NAD+ deficiency will significantly reduce the level of glycolysis, TCA cycle and electron transport chain metabolism in T cells. Through the experiment of replenishing ATP, the researchers found that the lack of NAD+ mainly inhibits the production of ATP in T cells, thereby reducing the level of T cell activation. 2.The NAD+ salvage synthesis pathway regulated by NAMPT is essential for T cell activation The metabolic reprogramming process regulates the activation and differentiation of immune cells. Targeting T cell metabolism provides an opportunity to modulate the immune response in a cellular way. Immune cells in the tumor microenvironment, their own metabolic level will also be correspondingly affected. The researchers in this article have discovered the important role of NAMPT in the activation of T cells through genome-wide sgRNA screening and metabolism-related small molecule inhibitor screening experiments. Nicotinamide adenine dinucleotide (NAD+) is a coenzyme for redox reactions and can be synthesized through the salvage pathway, de novo synthesis pathway, and Preiss-Handler pathway. The NAMPT metabolic enzyme is mainly involved in the NAD+ salvage synthesis pathway. Analysis of clinical tumor samples found that in tumor-infiltrating T cells, their NAD+ levels and NAMPT levels were lower than other T cells. Researchers speculate that NAD+ levels may be one of the factors that affect the anti-tumor activity of tumor-infiltrating T cells. 3.Supplement NAD+ to enhance the anti-tumor activity of T cells Immunotherapy has been exploratory research in cancer treatment, but the main problem is the best treatment strategy and the effectiveness of immunotherapy in the overall population. Researchers want to study whether enhancing the activation ability of T cells by supplementing NAD+ levels can enhance the effect of T cell-based immunotherapy. At the same time, in the anti-CD19 CAR-T therapy model and anti-PD-1 immune checkpoint inhibitor therapy model, it was verified that supplementation of NAD+ significantly enhanced the tumor-killing effect of T cells. The researchers found that in the anti-CD19 CAR-T treatment model, almost all mice in the CAR-T treatment group supplemented with NAD+ achieved tumor clearance, while the CAR-T treatment group without NAD+ supplemented only about 20 % Of mice achieved tumor clearance. Consistent with this, in the anti-PD-1 immune checkpoint inhibitor treatment model, B16F10 tumors are relatively tolerant to anti-PD-1 treatment, and the inhibitory effect is not significant. However, the growth of B16F10 tumors in the anti-PD-1 and NAD+ treatment group could be significantly inhibited. Based on this, NAD+ supplementation can enhance the anti-tumor effect of T cell-based immunotherapy. 4.How to supplement NAD+ The NAD+ molecule is large and cannot be directly absorbed and utilized by the human body. The NAD+ directly ingested orally is mainly hydrolyzed by brush border cells in the small intestine. In terms of thinking, there is indeed another way to supplement NAD+, which is to find a way to supplement a certain substance so that it can synthesize NAD+ autonomously in the human body. There are three ways to synthesize NAD+ in the human body: Preiss-Handler pathway, de novo synthesis pathway and salvage synthesis pathway. Although the three ways can synthesize NAD+, there is also a primary and secondary distinction. Among them, the NAD+ produced by the first two synthetic pathways only accounts for about 15% of the total human NAD+, and the remaining 85% is achieved through the way of remedial synthesis. In other words, the salvage synthesis pathway is the key to the human body to supplement NAD+. Among the precursors of NAD+, nicotinamide (NAM), NMN and nicotinamide ribose (NR) all synthesize NAD+ through a salvage synthesis pathway, so these three substances have become the body's choice for supplementing NAD+. Although NR itself has no side effects, in the process of NAD+ synthesis, most of it is not directly converted into NMN, but needs to be digested into NAM first, and then participate in the synthesis of NMN, which still cannot escape the limitation of rate-limiting enzymes. Therefore, the ability to supplement NAD+ through oral administration of NR is also limited . As a precursor for supplementing NAD+, NMN not only bypasses the restriction of rate-limiting enzymes, but is also absorbed very quickly in the body and can be directly converted into NAD+. Therefore, it can be used as a direct, rapid and effective method to supplement NAD+. Expert Reviews: Xu Chenqi (Excellence and Innovation Center of Molecular Cell Science, Chinese Academy of Sciences, Immunology Research Expert) Cancer treatment is a problem in the world. The development of immunotherapy has made up for the limitations of traditional cancer treatment and expanded the treatment methods of doctors. Cancer immunotherapy can be divided into immune checkpoint blocking therapy, engineered T cell therapy, tumor vaccine, etc. These treatment methods have played a certain role in the clinical treatment of cancer. At the same time, this also makes the current focus of immunotherapy research on how to further enhance the effect of immunotherapy and expand the beneficiaries of immunotherapy.
1. Introduction The gut microbiota has long been regarded as one of the key elements contributing to the regulation of host health. Any changes in the composition or quality of the gut microbiota may have physiological consequences for the host. To determine the effect of sweetener stevia (also known as stevioside) on the gut microbiome of healthy population, the stool samples are collected from healthy participants who consume with or without five drops of the sweetener stevia twice daily. Following analyses of 16S rRNA sequencing method, no large-scale change is found in the gut microbiota post 12 weeks of consumption with stevia, hinting the safety of stevia. 2. Insignificant changes in the alpha or beta diversity following consumption of stevia It is discovered that there is no significant difference in alpha diversity (in terms of observed taxa, evenness and Shannon Index) and beta diversity (with regard to PCoA, PERMANOVA, and Jaccard Index) between groups. Nevertheless, PCoA plots shows strong separation along the x-axis. In addition, the community composition in each group is relatively even over time and equally diverse. 3. No clear difference in relative abundances of taxa At the genus level, relative abundances are similar between the control and stevia groups. No major difference is observed in relative abundances at the class, order and family level. Strikingly, butyricoccus is the only one identified taxon exhibiting significant difference at baseline, but not after 12 weeks of stevia consumption. Moreover, Collinsella and Aldercreutzia are two coprococcus species identified as explicitly different at baseline (one higher and one lower when comparing stevia vs. control), which however are significantly elevated after 12 weeks of consumption with stevia. 4. The safe intake volume of sweetener steviol glycosides In the European Food Safety Authority (EFSA), there is a Panel on Food Additives and Flavourings (FAF), which is responsible for evaluating the safety of food additives and establishing acceptable daily intake levels for safe use. Steviol glycosides, one of the extract from stevia, is evaluated by the FAF as well. In accordance to the latest toxicological test, this sweeter is not genotoxic and carcinogenic, without any adverse effects on the human reproductive system or growing children. The expert group has set the acceptable daily intake (ADI) of steviol glycosides at 4 milligrams per kilogram of body weight per day, which is consistent with the level determined by the Joint Expert Committee on Food Additives (JECFA) administered by the US Food and Agriculture Organization (FAO) and the World Health Organization (WHO). 5. Conclusion Regular, long-term consumption of stevia does not overtly alter the composition of the human gut microbiotia. Stevia can be safe as long as the intake volume is controlled appropriately.

Introduction Cardiovascular diseases (CVD) poses huge economic burden and great threat to the life of patients, even surpassing Alzheimer's disease and diabetes. 17.9 million people in the world die from CVD, with indirect treatment costs of $237 billion per year, which are projected to increase to $368 billion by 2035. It has been reported that the deficiency or imbalance of oxidized nicotinamide adenine dinucleotide phosphate (NADP+)/reduced nicotinamide adenine dinucleotide phosphate (NADPH) redox couple has been linked to a variety of pathological conditions including CVD. NADP(H) redox couple as cofactor/electron carrier in cardiommyocytes NADPH is an essential cofactor of glutathione reductase (GR) and thioredoxin reductase (TRs) in cardiommyocytes, with a crucial role in maintaining cellular redox homeostasis and energy metabolism. GR catalyzes the recycling of Glutathion (GSH) from oxidized glutathione (GSSG), and TRs reduces oxidized Trx-S2 into Trx-(SH)2. Simultaneously, both enzymes require NADPH as an electron donor and oxidize it to NADP+. Once O2•− is formed, for example, from NOXs in the cytosol and from mitochondrial electron transport chain (ETC), cytosolic CuZnSOD and mitochondrial MnSOD will reduce it to H2O2. GSH can be used by glutathione peroxidase (GPx) to reduce H2O2 further to water. Trx-(SH)2 provides reducing equivalents for Prx in the removal of H2O2. The connection of NADP(H) with cardiovascular pathologies NADP(H) plays a dual role in cardiovascular pathologies. On the one hand, the reduced NADPH can result in significant antioxidant deficiencies and intracellular accumulation of free radicals, which triggers lipid peroxidation, inflammation, and vascular dysfunction, ultimately exacerbating the course of atherosclerosisoxidase. On the other hand, high NADPH level can give rise to myocardial injury by inducing reductive stress and enhancing reactive oxygen species (ROS) production. Conclusion Changes in cellular NADP(H) content affect the intermediary metabolism of cardiac function, especially in diseased myocardium. Maintaining the balance between NADP+ and NADPH in cardiommyocytes is critically important for the treatment of CVD. Either deficiency or excess NADP(H) levels can lead to imbalances in cellular redox state and metabolic homeostasis, resulting in energy stress, redox stress, and ultimately disease state. NADP(H) has an important therapeutic value in CVD. Reference Sun Y, Wu D, Hu Q. NADP+/NADPH in Metabolism and its Relation to Cardiovascular Pathologies. Curr Med Chem.
