Metabolic engineering of Escherichia coli for biosynthesis of β-nicotinamide mononucleotide from nicotinamide was written by Liu, Yang;Yu, Bo. And the article was included in Microbial Biotechnology in 2021.Name: ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate The following contents are mentioned in the article:

The β-NMN (NMN) is a key intermediate of an essential coenzyme for cellular redox reactions, NAD. Administration of NMN is reported to improve various symptoms, such as diabetes and age-related physiol. decline. Thus, NMN is attracting much attention as a promising nutraceutical. Here, we engineered an Escherichia coli strain to produce NMN from cheap substrate nicotinamide (NAM) and glucose. The supply of in vivo precursor phosphoribosyl pyrophosphate (PRPP) and ATP was enhanced by strengthening the metabolic flux from glucose. A nicotinamide phosphoribosyltransferase with high activity was newly screened, which is the key enzyme for converting NAM to NMN with PRPP as cofactor. Notably, the E. coli endogenous protein YgcS, which function is primarily in the uptake of sugars, was firstly proven to be beneficial for NMN production in this study. Fine-tuning regulation of ygcS gene expression in the engineered E. coli strain increased NMN production Combined with process optimization of whole-cell biocatalysts reaction, a final NMN titer of 496.2 mg l^-1 was obtained. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Name: ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate).

((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Name: ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate

Inhibitory effects of metabolites isolated from Artemisia dracunculus L. against the human carbonic anhydrase I (hCA I) and II (hCA II) was written by Aydin, Tuba;Yurtvermez, Bayram;Senturk, Murat;Kazaz, Cavit;Cakir, Ahmet. And the article was included in Records of Natural Products in 2019.Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide The following contents are mentioned in the article:

Tarragon or Dragon′s-wort (Artemisia dracunculus L.) is widely used as spice and in traditional medicine in various regions of the world. Inhibitory effects of the n-hexane, dichloromethane, ethanol and methanol extracts of the leaves of tarragon on the human carbonic anhydrase (hCA) I and II enzymes were investigated. Dichloromethane extract exhibited the strongest activity with lowest IC50 value (0.020 and 0.031 μg/mL, resp.). The chromatog. studies on the dichloromethane extract of tarragon allowed the isolation of six known strong inhibitors of hCA isoenzymes as trans-anethole, stigmasterol, herniarin, (2E,4E)-N-isobutylundeca-2,4-dien-8,10- diynamide, (2E,4E)-1-(piperidin-1-yl)undeca-2,4-diene-8,10-diyn-1-one and 1-(4′-methoxyphenyl)-1,2,3- trihydroxypropane. The compound, 1-(4′-methoxyphenyl)-1,2,3-trihydroxypropane was isolated from tarragon for the first time in this study. Among the tested compounds, 1-(4′-methoxyphenyl)-1,2,3-trihydroxypropane showed the highest inhibitiory impact on both hCA isoenzymes. Also its IC50 values were found lower than pos. control, acetazolamide. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide).

(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The solubilities of amides and esters are roughly comparable. Typically amides are less soluble than comparable amines and carboxylic acids since these compounds can both donate and accept hydrogen bonds. Tertiary amides, with the important exception of N,N-dimethylformamide, exhibit low solubility in water. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide

The global COVID-19 epidemic has spread rapidly around the world and caused the death of more than 5 million people. It is urgent to develop effective strategies to treat COVID-19 patients. Here, we revealed that SARS-CoV-2 infection resulted in the dysregulation of genes associated with NAD+ metabolism, immune response, and cell death in mice, similar to that in COVID-19 patients. We therefore investigated the effect of treatment with NAD+ and its intermediate (NMN) and found that the pneumonia phenotypes, including excessive inflammatory cell infiltration, hemolysis, and embolization in SARS-CoV-2-infected lungs were significantly rescued. Cell death was suppressed substantially by NAD+ and NMN supplementation. More strikingly, NMN supplementation can protect 30% of aged mice infected with the lethal mouse-adapted SARS-CoV-2 from death. Mech., we found that NAD+ or NMN supplementation partially rescued the disturbed gene expression and metabolism caused by SARS-CoV-2 infection. Thus, our in vivo mouse study supports trials for treating COVID-19 patients by targeting the NAD+ pathway. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Recommanded Product: ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate).

(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide

And the article was included in ACS Chemical Biology in 2018.Computed Properties of C14H25NO The following contents are mentioned in the article:

This report describes the development of a target-protein-oriented natural-products-isolation (TPO-NAPI) method for Hedgehog inhibitors and the direct GLI1 inhibitor, 5′-O-methyl-3-hydroxyflemingin A , which inhibited hedgehog (Hh) signal transduction and diminished characteristics of cancer stem cells. Eight natural products (including three newly described products) that directly bind to GLI1 were rapidly obtained via the TPO-NAPI method developed using GLI1 protein-immobilized beads. 5′-O-Methyl-3-hydroxyflemingin A inhibited Hh signaling (IC₅₀ 7.3 μM), leading to decreasing production of the Hh target proteins BCL2, PTCH1, and BMI1. 5′-O-Methyl-3-hydroxyflemingin A was cytotoxic to Hh-related cancer cells. CD experiments revealed that 5′-O-methyl-3-hydroxyflemingin A directly bound GLI1 (K_d = 7.7 μM). Moreover, 5′-O-methyl-3-hydroxyflemingin A diminished cancer stem cell characters of Huh7 such as sphere formation and production of the cancer stem cell marker EpCAM. These results suggest that Hh inhibitors can efficiently suppress the activity of cancer stem cells.

(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides are stable compounds. The lower-melting members (such as acetamide) can be readily purified by fractional distillation. Most amides are solids which have low solubilities in water.Computed Properties of C14H25NO

And the article was included in Journal of Pharmaceutical and Biomedical Analysis in 2015.Product Details of 18836-52-7 The following contents are mentioned in the article:

In this study, a new type of single quadrupole mass spectrometric detector was implemented in transdermal research. The local skin pharmacokinetic properties of the plant N-alkylamides (NAAs) pellitorine and anacycline, present in an Anacyclus pyrethrum extract, and spilanthol, present in a Spilanthes acmella extract were investigated. This single quad MS detection method showed great advantages compared to the traditional UV detector. The NAAs could be identified and quantified in the samples with an ultra performance liquid chromatog. (UPLC)-single quad MS detection system, even if they were not separated, which is a requirement when using an UV-detector. Another advantage of the UPLC-MS system is that lower limit of detection values could be obtained allowing a more accurate and precise determination of the exptl. lag time in the in vitro skin permeation experiments To conclude, this single quad MS detector coupled to UPLC is a useful anal. tool with improved performance compared to high performance liquid chromatog.

Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Product Details of 18836-52-7

Protective effects of amide constituents from the fruit of Piper chaba on D-galactosamine/TNF-α-induced cell death in mouse hepatocytes was written by Matsuda, Hisashi;Ninomiya, Kiyofumi;Morikawa, Toshio;Yasuda, Daisuke;Yamaguchi, Itadaki;Yoshikawa, Masayuki. And the article was included in Bioorganic & Medicinal Chemistry Letters in 2008.Reference of 18836-52-7 The following contents are mentioned in the article:

The methanolic extract from the fruit of Piper chaba (Piperaceae) was found to have a hepatoprotective effect on D-galactosamine (D-GalN)/lipopolysaccharide (LPS)-induced liver injury in mice. From the Et acetate-soluble fraction, a new amide constituent named piperchabamide E (I) together with twenty known amide constituents (e.g., piperine, piperchabamides A-D, and piperanine) and two aromatic constituents were isolated as the hepatoprotective constituents. With regard to structure-activity relationships, the amide moiety and the 1,9-decadiene structure between the benzene ring and amide moiety were suggested to be important for strong inhibition of D-GalN/tumor necrosis factor-α (TNF-α)-induced death of hepatocytes. Furthermore, a principal amide constituent, piperine, dose-dependently inhibited increase in serum GPT and GOT levels at doses of 2.5-10 mg/kg (p.o.) in D-GalN/LPS-treated mice, and this inhibitory effect was suggested to depend on the reduced sensitivity of hepatocytes to TNF-α.

Studies have shown that storing pre-rigor frozen fish at subzero temperatures before thawing might suppress pH drop after thawing in some migratory fish. Therefore, the mechanisms involved in pH maintenance and the effects on the quality of fish muscle were investigated here. Frozen spotted mackerel (Scomber australasicus) was stored at -10°C for 1-10 d (hereinafter referred to as “-10°C treatments”). pH, water retention, and the changes in primary metabolite concentrations were investigated in the frozen and thawed muscles. When the -10°C treatment lasted for 5 d or longer, the thawed muscle maintained a min. pH of 6.2, and the water-retention and water-reabsorption capacities of the frozen-thawed spotted mackerel muscle of -10°C treatment samples increased compared with the control sample. In the -10°C treatments, NAD (NAD) was consumed and glycolytic intermediate products accumulated in the frozen muscle. This result suggests anaerobic glycolysis was inhibited. The results of this investigation indicate that -10°C treatments before thawing may increase the meat quality in frozen spotted mackerel. This study involved multiple reactions and reactants, such as ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate (cas: 1094-61-7Quality Control of ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate).

Amides include many other important biological compounds, as well as many drugs like paracetamol, penicillin and LSD. Low-molecular-weight amides, such as dimethylformamide, are common solvents. Amides can be recrystallised from large quantities of water, ethanol, ethanol/ether, aqueous ethanol, chloroform/toluene, chloroform or acetic acid. The likely impurities are the parent acids or the alkyl esters from which they have been made. The former can be removed by thorough washing with aqueous ammonia followed by recrystallisation, whereas elimination of the latter is by trituration or recrystallisation from an organic solvent.Quality Control of ((2R,3S,4R,5R)-5-(3-Carbamoylpyridin-1-ium-1-yl)-3,4-dihydroxytetrahydrofuran-2-yl)methyl hydrogen phosphate
