The Chinese name of NMNH is "reduced nicotinamide mononucleotide". NMNH is an amorphous yellow powder. NMNH increases NAD+ levels faster and at a higher concentration, on average 5 times that of NMN. NMNH has been industrialized and has a purity of ≥99%. It is available in two forms: free acid and sodium salt.
BONTAC is a reliable partner that we have been working with for many years. The purity of their coenzyme is very high. Their COA can achieve relatively high test results.
I discovered BONTAC in 2014 because David's article in cell about NAD and NMN related showed that he used BONTAC's NMN for his experimental material. Then we found them in China. After so many years of cooperation, I think it is a very good company.
I think green, healthy and high purity are the advantages of BONTAC's products compared with others. I still work with them to this day.
In 2017, we chose BONTAC's coenzyme, during which our team encountered many technical problems and consulted their technical team, which were able to give us good solutions. Their products are shipped very fast and they work more efficiently.
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.
Recently, a piece of good news came from the Japan Patent Office (one of the largest patent offices in the world) across the ocean to Shenzhen. The patent for "A STABLE NICOTINAMIDE RIBOSE COMPOSITION AND ITS PREPARATION METHOD" applied by Bontac was approved and issued a certificate. This invention patent is of great significance to the stability of Bontac coenzyme series products. This is another new recently patent obtained by Bontac after accumulating more than 150 patent applications. Such impressive achievements in scientific research are undoubtedly the best commendation for the innovative spirit of Bontac Biotech. Invention Title: A STABLE NICOTINAMIDE RIBOSE COMPOSITION AND ITS PREPARATION METHOD Technical advantages: Industrial artificial preparation of nicotinamide ribosehave made considerable progress to prepare relatively pure nicotinamide ribose at a lower cost. However, the monomer will become a viscous solid within a few seconds or minutes under ambient temperature and humidity as nicotinamide ribose is very easy to absorb moisture, and will disintegrate into oil within a few hours. In order to keep nicotinamide ribose as a dry solid, it needs to be stored in an absolutely dry environment, or frozen stored at about -20°C, which severely restricts the commercial application and promotion of nicotinamide ribose. Therefore, the development of stable nicotinamide ribose products has become a major problem that needs to be solved urgently. The purpose of the present invention is to solve the technical problem that the nicotinamide ribose monomer mentioned in the above background art is difficult to preserve and cannot be promoted and applied because it is very easy to absorb moisture and decompose. The invention provides a nicotinamide ribose composition with stable properties, easy storage, transportation and use. Only by continuously innovating technology can we adapt to the new opportunities in the new era, "respond to all changes" before new challenges, and produce a qualitative leap based on quantity. In the current favorable situation, Bontac Biotech's innovation plan is still non-stop, focusing on the overall market direction, paying attention to every link, solving every subtle problem, and writing Bontac's legend with active innovation. At this stage, Bontac Bio will continue to build a better R&D team, increase investment in scientific research, create better products for our customers, and empower greater value.
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.
With the epidemic control policies loosening worldwide, residents in China, India, Malaysia, Japan and Singapore have suffered a shortage of medicines to varying degrees. But on the other hand, the type of medicines available to the public is dynamically increasing, and at present the anti-Covid-19 stars available on the market include Paxlovid, NMN, etc. What are the similarities and differences between the two in terms of mechanism of preventing and treating the Coronavirus? It is necessary to briefly make out the principle of Covid-19 infection in human cells before discussing the mechanism of action of Paxlovid and NMN. How SARS-CoV-2 infect cells? First, the mature Covid-19 (as shown in Figure 1) is mainly composed of structure proteins including spike (S) protein, nucleocapsid (N) protein, membrane (M) protein and envelope (E) protein and RNA viral gene. Figure 1. SARS-Cov-2 structure The SARS-CoV-2 opens a channel into the cell by its S protein through recognizing and binding to the ACE2 protein receptor of host cells in vivo. After entering the host cell, the SARS-CoV-2 initiates transcription and translation activities, replicating plenty of SARS-CoV-2, disrupting the cell structure and interfering with the normal cell function. Under this mechanism of action, the supplement of medicine directly comes into play on the sides of spike S protein of the Covid-19 and the ACE2 protein of host cells in human body. Paxlovid prevents the synthesis of S proteins of SARS-CoV-2. The mechanism of Paxlovid to treat Covid-19 Paxlovid was made up with two main ingredients, Nirmatrelvir and Ritonavir. Nirmatrelvir combats SARS-CoV-2 by blocking the synthesis of S proteins.The gene information of all SARS-CoV-2 proteins only take over 1/3 of the right side of RNA strand (as shown in Figure 2), and the remaining 2/3 of the RNA gene strand is used for transcription and translation for multiple proteins to synthesize the polyprotein. After the polyprotein is synthesized, it will be cleaved into several functional proteins likely S protein by virus proteases. Figure 2. RNA structure In short, when the SARS-CoV-2 replicates, the RNA initiates transcription and translation for proteins in bulk and then proteases cleave it to form structural proteins (S protein). The main proteases used when replicating is CL3. Nirmatrelvir of Paxlovid binds to the CL3 protease to prevent the cleavage of the SARS-CoV-2 polyprotein so as to interrupt the protein synthesis of viral. (As shown in Figure 3). What’s more, another ingredient, Ritonavir, works by maintaining the concentration of Nirmatrelvir in the body, prolonging and enhancing its efficacy and maintaining the interruption strength for the replicating protease CL3. Figure 3.CL3 in translation The mechanism of NMN to prevent and treat Covid-19 NMN prevents Covid-19 infection by protecting DNA and reducing ACE2 expression, shutting down the pathway of ACE2 protein into human cells. The researchers found that DNA damages accumulates intracellular ACE2 receptor proteins. However, these two enzymes to repair DNA damage, sirtuins and PARP, need to be to motivated by NAD+. Studies showed that NMN supplementation is effective in increasing NAD+ levels and thus reducing ACE2 protein expression. As it demonstrates that experiment proved that a reduction in ACE2 expression after infected with the SARS-CoV-2, along with a reduction in viral load and tissue damage in the lungs (as shown in Figure 4) based on the situation that 200mg/kg of NMN fed to old mice aged 12 months for 7 days. Figure 4. NMN performance in recuding viral loads The study not only reaffirms the convincing for NMN to treat Covid-19 infection, but based on its proven ability to reduce lung pathological damage and even death in mice infected with neointima, NMN may be used in clinical trials to treat patients with Covid-19 infection. It is clear from the above principles of action that both Paxlovid and NMN work on original source of infection to treat and prevent Covid-19. The difference between the two is that Paxlovid interferes with the replication of the virus while NMN closes the door to the entry of Covid-19 into human cells. Both different mechanisms of action are in principle effective in preventing the invasion of Covid-19. References 1.
