What is the mechanism of NADH powder of Action?

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.

What are the challenging in marketing for NMNH manufacturer?

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.

How to choose a real NMNH manufacturer?

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.

Frontier Dynamics on the Molecular Mechanism of Ginsenoside Rh2 Against Tumor

Introduction Ginsenoside Rh2, one protopanaxadiol (PPD)-type rare ginsenoside in Panax ginseng, is uncovered to possibly have broad-spectrum pharmacological activity in diversified tumors. It is utilized as an adjuvant drug for preoperative neoadjuvant chemotherapy, postoperative adjuvant chemotherapy, and rescue treatment of advanced cancer, which has been a research hotspot in recent years. Current states on cancer therapies Cancer has emerged as the second largest cause for death across the world, with approximately 9.6 million cancer-related deaths in 2018, in accordance with the statistical report by World Health Organization (WHO). Radiotherapy, chemotherapy and surgery are the preferred option for cancer, whose efficacy is however limited by the tumor relapse and drug resistance, requiring a patch such as adjuvant drugs to fix the bug. For anticancer treatment, over 60% of the approved and pre-new drug application candidates are natural products or synthetic molecules based upon natural product molecular skeletons. Strikingly, ginsenosides act as a promising therapeutic target by virtue of its pharmacological activities such as immune adjustment, anti-tumor, anti-oxidation, and protection of the heart and cerebral vessels. 20(S) ginsenoside Rh2 vs. 20(R) ginsenoside Rh2 There are two stereoisomeric forms of ginsenoside Rh2, namely 20(S) ginsenoside Rh2 and 20(R) ginsenoside Rh2. Relative to the (20R) ginsenoside Rh2, (20S) ginsenoside Rh2 has higher cytotoxic activity towards cancer cells. In a previously reported study, the half maximal inhibitory concentration values of 20(S) ginsenoside Rh2 and 20(R) ginsenoside Rh2 in A549 cells are 45.7 and 53.6 µM, respectively. The underlying mechanisms of ginsenoside Rh2 against tumor Mechanically, the anti-tumor effects of ginsenoside Rh2 are realized by enhancing the body’s immune activity to regulate microenvironment, inhibiting differentiation, angiogenesis, proliferation, invasion, and metastasis of tumor cells, inducing the apoptosis, cell cycle arrest, autophagy, superoxide and reactive oxygen species, and reversing the drug resistance via regulating a series of important tumor-related signaling pathway. For instance, ginsenoside Rh2 can activate CD4+ and CD8a+ T lymphocytes, promote their invasion, and enhance the killing effect of lymphocytes on B16-F10 melanoma cells in a concentration-dependent manner. Besides, the number of tumor cells in the G0/G1 phase is increased significantly post treatment with ginsenoside Rh2 and 5-FU, by which the expansion and migration of tumor cells are effectively hampered. Additionally, the ginsenoside Rh2 downregulates the levels of drug-resistance-related genes (eg. MRP1, MDR1, LRP and GST), making colorectal cancer cells more sensitive to 5-FU. Conclusion Ginsenoside Rh2 plays multifunctional roles in both tumor treatment and tumor microenvironment immunomodulation, which may become a promising choice of medication for patients with tumors in the future.

Is stevioside a sugar reducer or a health killer?

1. Introduction On July 2023, the World Health Organization (WHO) has classified the soda sweetener aspartame as a possible carcinogen, but said that aspartame is safe to consume within a daily limit of 40 milligrams per kilogram of a person’s body weight according to the latest assessment results regarding the impacts of the non-sugar sweetener aspartame upon the health. How about another sweetener stevioside? Is stevioside a sugar reducer or a health killer? 2. Current situation on stevioside Stevioside (also termed stevia glycoside) has been regarded as “the third largest source of natural sugar across the world” by virtue of its low calorie, high sweetness, good stability and low price, which is widely used in medicine, daily chemicals, beverage, food, brewing and other industries.  3. Regulatory application and control of stevioside The aforementioned report of WHO on the possible carcinogenesis of soda sweetener aspartame is based on high intake. An adult weighing 70 kilograms or 154 pounds would have to drink more than 9 to 14 cans of aspartame-containing soda daily to exceed the limit and potentially face health risks. There is no need to be worry about the risk of carcinogenesis in the case of healthy intake. The same situation is applicable to another sweetener stevioside. Stevioside is approved to be sweetener in food in countries like Mainland China, Japan, Korea, Australia, New Zealand, the USA and European Union. In China, there are detail specifications on the food additive stevioside (GB 2760-2014). 4. The therapeutic properties of stevioside 4.1 Antitumor effect Stevioside can be applied as a valuable chemotherapy candidate to be further investigated for cancer therapy. The activity of the well-known tumor promoter, 12-O-tetradecanoylphorbol-13-acetate (TPA), is successfully inhibited with stevioside in a murine skin-cancer model. In addition, stevioside can reduce mammary adenoma incidence in F344 rats. 4.2 Anti-hypertensive activity The hypotensive effect observed in rats after chronic oral administration (30 days) of 2.67 g stevia leaves/day has been confirmed in spontaneously hypertensive rats. In that murine model, stevioside (100 mg/kg; i.v.) is able to reduce blood pressure with no change in serum epinephrine, norepinephrine, or dopamine levels. 4.3 Anti-diabetics In diabetic rats, stevioside (0.2 g/kg; i.v. administration) decreases glucose blood levels, yet increases insulin responses and reactions to an intravenous glucose tolerance test (IVGT). Also, stevioside enhances insulin levels above basal during the IVGT, without altering blood glucose response, in normal rats, hinting its potential as a drug candidate for type 2 diabetes. 4.4 Inhibition of pathogenic bacteria Stevioside has demonstrated antibacterial action on various foodborne pathogenic bacteria, including Escherichia coli, a wellknown etiologic agent of severe diarrhea. Regarding antiviral properties, stevioside seems to impede binding of rotavirus to host cells. Rotavirus is commonly associated with pediatric gastroenteritis. 4.5 Anti-inflammatory property In lipopolysaccharide (LPS)-stimulated THP1 cells, stevioside (1mM) inhibits NF-κB. Moreover, stevioside prevents in vitro upregulation of genes involved in liver inflammation. In addition,  silico assays demonstrate its antagonistic action in two proinflammatory receptors: tumor necrosis factor receptor (TNFR)-1 and Toll-like receptor (TLR)-4-MD2.  4.6 Antioxidant capability The antioxidant effects of stevioside and rebaudioside A have been confirmed in a fish model, both of which effectively control lipoperoxidation and protein carbonylation. Furthermore, stevioside prevents oxidative DNA damage in the livers and kidneys of a type 2 diabetes murine model. 5 Conclusion As long as the intake is properly controlled, stevioside can be very useful. Stevioside holds a great promise in the clinical treatment and daily health care. Reference Orellana-Paucar A. M. (2023).

A Novel Way Out of the Dilemma in the Treatment of Breast Cancer: Rh2-Lipo

Introduction Ginsenoside Rh2 nanoliposome formulation has been proved to effectively target and deliver drugs to the tumor site, with less side effects and higher treatment efficiency, holding great promise in the treatment of tumors including breast cancer. Dilemma of traditional tumor therapies The traditional tumor therapies (eg. surgery, radiation, and chemotherapy) carry the high risks of damaging normal tissues and incompletely eradicating the cancer. Strikingly, nanotechnology opens up novel opportunities for tumor treatment, which can enhance earlier diagnosis through in vitro assays, promote imaging capabilities for diagnosis and treatment monitoring, and improve therapeutic outcomes by refining targeting precision, augmenting localized drug efficacy as well as minimizing systemic toxicity. Limitations of conventional liposome formulations The conventional liposome formations encounter a lot of bottlenecks in improving the progress of tumor microenvironment, a vital complex ecosystem for cancer development and metastasis. In addition, these formulations face the trouble (eg. issues related to religion tradition and vegetarianism) brought by cholesterol, an ingredient of traditional liposomes. Moreover, there are disadvantages of complicated fabrication process, low targeting efficiency of ligand-modified liposomes as well as extended circulation time of liposomes caused by the utilization of polyethylene glycol. Merits of PTX-Rh2-Lipo PTX-Rh2-lipo, a potential nanomedicine, has an overtly smaller particle size and higher zeta potential when compared with PTX-C-Lipo. Both types of liposomes show analogous encapsulation and stabilization abilities, as manifested by similar polydispersity index, encapsulation efficiency, and loading efficiency.  Different from conventional wooden liposomes, PTX-Rh2-Lipo has the merits of enhanced uptake in tumor-associated fibroblasts L929 and 4T1 breast cancer cells, high targeting and penetration capacity, cytotoxicity against L929 fibroblasts, normalization of the vessel network, and depletion of stromal collagen. Conclusion Rh2-lipo cannot kill 4T1 breast cancer cells alone, despite of its stronger penetration ability in the tumors. Yet, it can act as a delivery vehicle for paclitaxel (PTX) to enhance its antitumor properties. Specifically, in this novel Rh2-Lipo-based nano-carrier PTX-Rh2-lipo, ginsenoside Rh2 can not only serve as a multifunctional membrane material to stabilize the structure and prolong the blood circulation of liposomes, but also works as an active ingredient to synergically enhance the efficacy of anti-cancer drugs by remodeling tumor-associated microenvironment and stimulating the immune system.
