Metode pembuatan bubuk NMN

Bubuk NMN pada umumnya diproduksi melalui sintesis kimia atau enzimatik, atau biosintesis fermentasi. Ada pro dan kontra untuk ketiga metode tersebut.
Chemical synthesis is expensive and labor intensive, and all raw ingredients used are categorized as “unnatural,” i.e., not from biological systems. There are, however, some advantages from the manufacturer’s perspective. The yield is well suited to mass NMN powder production, and all of those unnatural raw ingredients can be carefully controlled. But there are a number of drawbacks as well. Some of the solvents used in the manufacturing process are seriously bad from an environmental standpoint, and impurities and by-products can be challenging to remove from the finished product – that’s seriously bad for the consumer.
Enzymatic production of NMN powder, on the other hand, is considered a “green preparation method.” Like the chemical route, it’s pricey, but it offers a higher yield and impressively high purity. The finished NMN ticks all the boxes – stable, easily absorbed, lightweight, low density, and a low molecular structure.
Fermentasi juga telah dieksplorasi sebagai metode produksi NMN, tetapi hasil, meskipun berkualitas tinggi, cukup buruk, sehingga banyak perusahaan suplemen dengan cukup bijaksana melihat ke proses lain yang lebih berkhasiat.

Pertanyaan yang Sering Diajukan

Apakah Anda punya pertanyaan?

Penuaan, sebagai proses alami diidentifikasi oleh penurunan regulasi produksi energi dalam mitokondria dari berbagai organ seperti otak, jaringan adiposa, kulit, hati, otot rangka dan pankreas karena penipisan NAD+ . Kadar NAD+ dalam tubuh menurun sebagai konsekuensi dari peningkatan enzim konsumsi NAD+ saat menua Ada tiga jalur biosintesis yang berbeda untuk menghasilkan NAD+ dalam sel mamalia termasuk sintesis de novo dari jalur triptofan, garam dan Preiss-Handler. Di antara ketiga jalur ini, NMN adalah interproduk yang terlibat dalam biosintesis NAD+ melalui jalur garam dan Preiss-Handler. Jalur penyelamatan adalah yang paling efisien dan rute utama untuk biosintesis NAD+, di mana nikotinamida dan 5-fosforibosyl-1-pirofosfat diubah menjadi NMN dengan enzim NAMPT diikuti dengan konjugasi ke ATP dan konversi ke NAD oleh NMNAT. Selain itu, enzim yang mengonsumsi NAD+ bertanggung jawab atas degradasi NAD+ dan konsekuensi pembentukan nikotinamida sebagai produk sampingan.

Keamanan bubuk NMN tidak dapat dinilai karena studi klinis dan toksikologi yang diperlukan belum selesai untuk menetapkan tingkat aman yang direkomendasikan untuk pemberian jangka panjang. Namun demikian, keamanan dan kemanjurannya tidak pasti dan tidak dapat diandalkan karena kebanyakan dari mereka belum kembali dengan pengujian praklinis dan klinis ilmiah yang ketat. Masalah ini muncul karena produsen ragu-ragu untuk membayar penelitian dan uji klinis karena potensi margin keuntungan yang lebih rendah, dan tidak ada lembaga yang berwenang untuk mengatur produk NMN karena seringkali produk yang dijual sebagai makanan fungsional daripada obat terapeutik yang diatur secara ketat. Oleh karena itu, proses persetujuan yang lebih ketat telah dituntut oleh kelompok advokasi konsumen yang meminta badan pengatur untuk menetapkan standar dan pembatasan untuk memasarkan produk kesehatan anti-penuaan, dengan mempertimbangkan keselamatan, kesehatan dan kesejahteraan pengguna merah N. obat mujarab untuk orang tua, karena meningkatkan kadar NAD bila tidak diperlukan dapat menghasilkan beberapa efek yang merugikan. Oleh karena itu, dosis dan frekuensi suplementasi NMN harus diresepkan dengan hati-hati tergantung pada jenis defisiensi terkait usia dan semua kondisi kesehatan lain yang dihadapi orang-orang. Prekursor NAD lainnya telah dipelajari untuk berbagai kekurangan terkait usia dan mereka digunakan untuk kekurangan tertentu, hanya setelah terbukti efektivitas dan aman digunakan. Oleh karena itu, prinsip yang sama juga harus diterapkan pada NMN

Pertama, periksa pabrik. Setelah beberapa penyaringan, NMN menyimpulkan bahwa konsumen yang langsung berhadapan dengan lebih memperhatikan pembangunan merek. Oleh karena itu, untuk merek yang bagus, kualitas adalah hal yang paling penting, dan hal pertama untuk mengontrol kualitas bahan baku adalah memeriksa pabrik. Perusahaan Bontac benar-benar memproduksi bubuk NMN berkualitas tinggi dengan caterias SGS. Kedua, kemurnian diuji. Kemurnian adalah salah satu parameter terpenting dari bubuk NMN. Jika NMN dengan kemurnian tinggi tidak dapat dijamin, zat yang tersisa kemungkinan akan melebihi standar yang relevan. Seperti yang ditunjukkan oleh sertifikat terlampir bahwa bubuk NMN yang diproduksi oleh Bontac mencapai kemurnian 99,9%. Akhirnya, diperlukan spektrum tes profesional untuk membuktikannya. Spektroskopi Resonansi Magnetik (NMR) dan spektrometri massa resolusi tinggi (HRMS). Biasanya melalui analisis kedua spektrum ini, struktur senyawa dapat ditentukan terlebih dahulu.

Penelitian terbaru membuktikan: Koenzim NAD+ dapat meningkatkan kekebalan tumor! Komentar Ahli dari Akademi Ilmu Pengetahuan Tiongkok

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.

Mekanisme Molekuler yang Mendasari Interaksi Antara NAD+/NMN dan DBC1

Introduction Oxidized form of nicotinamide adenine dinucleotide (NAD+) and its precursor nicotinamide mononucleotide (NMN) have been uncovered to restore DNA repair and prevent cancer progression via the deleted in breast cancer 1 (DBC1). This research is committed to deciphering the detailed molecular mechanisms. About DBC1 DBC1 is a nuclear protein initially cloned from a human chromosome 8p21 region, which can modulate diversified targets by protein-protein interaction, contributing to various cellular processes such as apoptosis, DNA repair, senescence, transcription, metabolism, circadian cycle, epigenetic regulation, cell proliferation, and tumorigenesis. The affinity and molecular binding mechanisms between NAD+/NMN and DBC1354–396 Under the help of nuclear magnetic resonance (NMR) and Isothermal titration calorimetry (ITC) experiments, it is verified that both NAD+ and NMN have a binding relationship with the NHD domain of DBC1. Specifically, NAD+ interacts with DBC1354-396 through hydrogen bonds, with a binding affinity (8.99 μM) nearly twice that of NMN (17.0 μM) and the key binding sites are primarily residues E363 and D372. The vital roles of E363 and D372 mutagenesis in ligand-protein interaction The N-terminal loop of DBC1354-396 encloses the small ligand within a local space, anchoring NAD+ and NMN to the protein through key amino acid residues E363 and D372 via hydrogen bonding. Conclusion Both NAD+ and its precursor NMN can bind to DBC1's NHD domain (DBC1354–396) at key sites E363 and D372, providing novel clues for the development of targeted therapies and drug research on DBC1-associated disease including tumors.

Suplementasi Prekursor NAD Ibu untuk Mengurangi Risiko Terkena CNDD

1. Pendahuluan Nicotinamide adenine dinucleotide (NAD) telah diungkapkan sebagai penting untuk perkembangan embrio. Pasien dengan varian genetik dalam jalur sintesis NAD+ de novo sering memiliki gangguan defisiensi NAD bawaan (CNDD), kondisi multisistem yang diwariskan dengan cara resesif autosomal. Dalam konteks defisiensi NAD+, semua organ dan sistem, bukan hanya tulang belakang, jantung, ginjal, dan anggota badan, dapat terpengaruh. 2. Hubungan antara NAD synthetase 1 (NADSYN1) dan CNDD Individu yang memberikan varian NADSYN1 biallelic memiliki fitur klinis yang mirip dengan mereka yang menderita CNDD. Hingga saat ini, hampir semua kasus CNDD yang diidentifikasi dapat dikaitkan dengan varian kehilangan fungsi biallelic di salah satu dari 3 gen nonredundan dari jalur sintesis NAD de novo, termasuk kynureninase (KYNU), 3-hydroxyanthranilate 3,4-dioxygenase (HAAO), atau NADSYN1. Di antara individu dengan CNDD yang diidentifikasi hingga saat ini, mereka yang memiliki varian NADSYN1 patogen biallelic adalah yang paling beragam dalam fenotip. 3. Dampak varian NADSYN1 terhadap aktivitas enzimatik dan fenotipe Secara khusus, NADSYN1 dapat mengkatalisis amidasi asam nikotinat adenin dinukleotida (NaAD) ke NAD. Varian patogen bialel pada NADSYN1 menyebabkan blok metabolisme di jalur de novo dan jalur Preiss-Handler, yang menyebabkan defisiensi NAD. Varian kehilangan fungsi NADSYN1 bialel berdampak pada metabolom NAD manusia. Fenotipe pasca kelahiran melibatkan kesulitan makan, keterlambatan perkembangan, perawakan pendek, dll. 4. Embriogenesis tikus terganggu oleh hilangnya NADSYN1 Pada embrio tikus NADSYN1-/- malformasi yang bergantung pada NAD terjadi ketika prekursor NAD makanan ibu terbatas selama kehamilan. Embrio Nadsyn1//- yang terkena paling sering menunjukkan malformasi ginjal, mata, dan paru-paru. 5. Efek pencegahan suplementasi prekursor NAD amidat terhadap CNDD Kehilangan embrio yang bergantung NADSYN1 dan malformasi pada tikus dapat dicegah dengan suplementasi makanan prekursor NAD amidat (NMN dan NAM) selama kehamilan. Prekursor NAD yang diturunkan dari diet ibu terutama menentukan perkembangan embrio yang sehat. 6. Kesimpulan Suplemen penambah NAD sangat penting bagi individu dengan varian kehilangan fungsi biallelic pada NADSYN1. Suplementasi prekursor NAD ibu, sampai batas tertentu, dapat mengurangi risiko terkena CNDD. Referensi Szot JO, Cuny H, Martin EM, dkk.
