What is the mechanism of NMN powder of anti-aging?

Aging, as a natural process is identified by downregulation of energy production in mitochondria of various organs such as brain, adipose tissue, skin, liver, skeletal muscle and pancreas due to the depletion of NAD+ . NAD+ levels in the body decrease as a consequence of increasing NAD+ consuming enzymes when aging There are three different biosynthesis pathways to produce NAD+ in mammalian cells including de novo synthesis from tryptophan, salt and Preiss-Handler pathways. Among these three pathways, NMN is an interproduct by is involved in NAD+ biosynthesis through salt and Preiss-Handler pathways. The salvage pathway is the most efficient and the main route for the NAD+ biosynthesis, in which nicotinamide and 5-phosphoribosyl-1-pyrophosphate are converted to NMN with the enzyme of NAMPT followed by conjugation to ATP and conversion to NAD by NMNAT. Furthermore, NAD+ consuming enzymes are responsible for degradation of NAD+ and consequence nt formation of nicotinamide as a by-product.

What are the challenges of marketing the NMN powder?

The safety of NMN powder cannot be assessed since required clinical and toxicological studies have not been completed yet to establish the recommended safe levels for long term administration. Nevertheless, their safety and efficacy are uncertain and unreliable since most of them have not been back by Rigorous scientific preclinical and clinical testing. This issue has been arisen as manufacturers are hesitant to pay for research and clinical trials due to potential lower profit margin, and there is no authorizing agency to regulate NMN products because it is often product sold as functional food than heavily regulated therapeutic drug. Therefore, more strict approval process has been demanded by consumer advocacy groups requesting regulatory agencies to set standard and restrictions for marketing anti-aging health products, considering safety, health and wellbeing of N red besumers. a panacea for the elderly, because boosting NAD levels when not required may yield some detrimental effects. Therefore, the dose and frequency of NMN supplementation should be carefully prescribed depending on the type of age-related deficiency and all other confronting health conditions of the people. Other NAD precursors over have been studied to diverse age-related deficiencies and they are used for particular deficiencies, only after they are proven for effectiveness and safe to use. Therefore, the same principle should be applied to NMN as well

How to choose a real NMN powder material manufacturer?

First, inspect the factory. After some screening, NMN companied 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 NMN 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 NMN cannot be guaranteed, the remaining substances are likely to exceed the relevant standards. As the attached certificates demonstrates that the NMN powder produced by Bontac reach the purity of 99.9%. Finally, a professional test spectrum is needed to prove it. Magnetic Resonance Spectroscopy (NMR) and high-resolution mass spectrometry (HRMS). Usually through the analysis of these two spectra, the structure of the compound ca n be preliminarily determined.

Mechanism for Preventing and Treating Covid-19: NMN VS Paxlovid

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.

Supplementing NAD+ precursors as a promising approach for DPN

1. Introduction Diabetic peripheral neuropathy (DPN) is one of the most frequent complications of diabetes, ans also a major cause of foot ulcers, disability, and eventual amputation. With the prolongation of the diabetes, about 50% of people with diabetes will eventually develop DPN. Notably, supplementing NAD+ precursors could alleviate DPN symptoms by increasing the NAD+ level and activating the sirtuin-1 (SIRT1) protein. 2. The reversal effect of NAD+ precursors on DPN In vitro, the Dorsal Root Ganglion neurons (DRGs) isolated from diabetic mice are exposed to the NAD+ precursor Nicotinamide Riboside (NR) or Nicotinamide Mononucleotide (NMN). It is found that the NAD+ level, the SIRT1 protein, and the deacetylation activity are elevated, followed by the boosted neurite growth, the improved nerve function, and the reversal of IENFD loss. In vivo, supplement of NMN or NR also offsets the neuropathy in C57BL6 mice induced by streptozotocin (STZ) or high fat diet (HFD), as manifested by the improved sensory function, normalized nerve conduction velocities, and restored intraepidermal nerve fibers. 3. The increase of neurite length in a SIRT1-dependent manner post the addition of NMN/NR SIRT1, one of the most unique NAD+ consuming enzymes, can protect against DPN when activated, which may attribute to the improved mitochondrial function and energy homeostasis. Apart from these, SIRT1 activity in the nucleus can deacetylate the transcriptional and co-transcriptional factors that regulate glucose homeostasis and fat oxidation. The activation of SIRT1 is critical for axonal regeneration. NMN/NR treatment or transfection with SIRT1 overexpression vector can directly facilitate the neurite growth in cultured DRG neurons, which however is hindered by the SIRT1 inhibitor EX527, hinting the significance of SIRT1. 4. The association of SARM1 with NMNAT2 in axonal degeneration of DPN Sterile alpha and Toll/interleukin-1 receptor motif-containing 1 (SARM1) controls the axonal degeneration and regeneration via a well-regulated system comprising NAD+ and NMN. NAD and NMNAT2 can boost vesicular glycolysis and axonal transport to maintain the axonal health. The mitochondrial localization of SARM1 complements the coordinated activity of NMNAT2 that promotes axonal survival. 5. Conclusion Supplementing NAD+ precursors may be a promising approach for the treatment of DPN. A SARM1 inhibitor coupled with either NR or NMN may be more effective than a single agent alone in preventing or treating DPN.

The Immuno-Enhancing Effect of Rh2-L on Double Emulsion Adjuvant Against Foot-and-Mouth Disease

1. Introduction At present, vaccine is the preferred option for the prevention of foot-and-mouth disease (FMD), for which the adjuvant is essential due to its strong role in boosting immune response associated with vaccine antigens. Herein, Rh2 liposomes (Rh2-L) are prepared by ethano injection methods, then loaded into a double emulsion adjuvant and emulsified into a Water-in-Oil-in-Water (W/O/W) emulsion, together with FMDV antigen, for the prevention of FMD. 2. About FMD FMD, also known as aphthous fever, is a viral and fulminating infectious disease in which the foot-and-mouth disease virus (FMDV) violates hoofed livestock such as cattle, pigs and sheep. Since FMD is a zoonotic disease with high incidence and fast transmission speed, FMD vaccination is significant for those with long-term contact with livestock or low immunity such as the herders, veterinarians and children. 3.The significance of transform Rh2 into Rh2-L By transformation of Rh2 into Rh2-L, on the one hand, the poor solubility and hemolysis of Rh2 can be mitigated to a large extent. On the other hand, Rh2-L functions as a liposome. Noteworthily, liposome itself has been revealed to be an adjuvant in vaccine design to improve immune response by interacting with antigen-presenting cells (APCs), increasing the representation of immune stimulants to APCs, and stimulating innate immunity. 4. The immune-enhancing effect of Rh2-L on FMD vaccine Rh2-L has a immune-enhancing effect, as evidenced by an increase in humoral and cellular immune responses. In the FMDV model, the group of the FMD vaccine prepared with double emulsion adjuvants containing Rh2-L presents a more desirable protective effect relative to other groups. This group has a higher neutralizing antibody titer, stronger lymphocyte proliferation responses, and higher levels of cellular and humoral immune cytokine production, including IFN-γ and IL-4. 5. Conclusion Rh2-L can further boost the immune effect of the double emulsion adjuvant against foot-and-mouth disease, which may be a promising and powerful platform for subunit vaccine adjuvant. 6.
