Polycystic ovary syndrome (PCOS) is a common endocrine disorder, defined by reproductive and endocrine abnormalities, with metabolic dysregulation including obesity, insulin resistance and hepatic steatosis. Recently, it was found that skeletal muscle insulin sensitivity could be improved in obese, post-menopausal, pre-diabetic women through treatment with NMN (NMN), a precursor to the prominent redox cofactor NAD (NAD⁺). Given that PCOS patients have a similar endocrine profile to these patients, we hypothesised that declining NAD levels in muscle might play a role in the pathogenesis of the metabolic syndrome associated with PCOS, and that this could be normalized through NMN treatment. Here, we tested the impact of NMN treatment on the metabolic syndrome of the dihydrotestosterone (DHT) induced mouse model of PCOS. We observed lower NAD levels in the muscle of PCOS mice, which was normalized by NMN treatment. PCOS mice were hyperinsulinemic, resulting in increased adiposity and hepatic lipid deposition. Strikingly, NMN treatment completely normalized these aspects of metabolic dysfunction. We propose that addressing the decline in skeletal muscle NAD levels associated with PCOS can normalize insulin sensitivity, preventing compensatory hyperinsulinemia, which drives obesity and hepatic lipid deposition, though we cannot discount an impact of NMN on other tissues to mediate these effects. These findings support further investigation into NMN treatment as a new therapy for normalizing the aberrant metabolic features of PCOS.

Self-Assembled Arene-Ruthenium-Based Rectangles for the Selective Sensing of Multi-Carboxylate Anions was written by Vajpayee, Vaishali;Song, Young-Ho;Lee, Min-Hyung;Kim, Hyun-Uk;Wang, Ming;Stang, Peter J.;Chi, Ki-Whan. And the article was included in Chemistry – A European Journal in 2011.Related Products of 53118-43-7 The following contents are mentioned in the article:

Novel arene-ruthenium [2+2] metalla-rectangles I and II were synthesized by self-assembly using dipyridyl amide ligand and arene-ruthenium acceptors (arene: benzoquinone, naphthacenedione) and characterized by NMR spectroscopy and ESI-MS. The solid-state structure of II was determined by x-ray diffraction and shows encapsulated di-Et ether mol. in the rectangular cavity of II. The luminescent II was further used for anion sensing with the amidic linkage serving as a hydrogen-bond donor site for anions and the ruthenium moiety serving as a signaling unit. A UV/visible titration study demonstrated that although II interacts very weakly with common monoanions as well as with flexible dicarboxylate anions such as malonate and succinate, it displays significant binding affinity (K>10³ in MeOH) for rigid multi-carboxylate anions such as oxalate, citrate, and tartrate, exhibiting a 1:1 stoichiometry. Probably 1:1 bidentate hydrogen bonding assisted by appropriate geometrical complementarity is mainly responsible for the increased affinity of II towards such anions. A fluorescence titration study revealed a large fluorescence enhancement of II upon binding to multi-carboxylate anions, which can be attributed to the blocking of the photoinduced electron-transfer process from the arene-Ru moiety to the amidic donor in II as a result of hydrogen bonding between the donor and the anion. This study involved multiple reactions and reactants, such as N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7Related Products of 53118-43-7).

N1,N2-Di(pyridin-4-yl)oxalamide (cas: 53118-43-7) 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 freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.Related Products of 53118-43-7

And the article was included in Molecules in 2017.Related Products of 18836-52-7 The following contents are mentioned in the article:

Anti-inflammatory compounds were investigated from the ethanol extract of the roots and rhizomes of Asarum heterotropoides var. mandshuricum, a traditional Chinese medicine called Xixin and used for pain and inflammatory. Nine new compounds were isolated, including six new lignans, neoasarinin A-C (1-3), neoasarininoside A and B (4 and 5), and asarinin B (7), and one new monoterpene, asarincin A (8), two new amides, asaramid II and III (10 and 11), and one new natural monoterpene, asaricin B (9), along with 37 known compounds (6, 12-47). Their structures and absolute configurations were elucidated on the basis of spectroscopic methods and chem. analyses. This is the first report of the absolute configuration of asarinin A (6). The 8-O-40 neolignans (1-5) were reported in the genus Asarum for the first time. The 15 compounds 17, 19, 22-25, 28, 31, 36, 40, 42, 43, 45-47 were isolated from the genus Asarum, and compounds 16, 32, 33, 37 and 39 were isolated from A. heterotropoides var. mandshuricum for the first time. Thirty-seven of the isolates were evaluated for anti-inflammatory activity against the release of β-glucuronidase in polymorphonuclear leukocytes (PMNs) induced by the platelet-activating factor (PAF), and compounds 1, 4, 7, 8, 14, 17-19, 22, 24, 25, 29, 30, 32, 33, 40-43, 45, and 46 showed potent anti-inflammatory activities in vitro, with 27.9%-72.6% inhibitions at 10^-5 mol/L. The results of anti-inflammatory assay suggested that lignans obtained from the CHCl₃ extract might be the main active components of Xixin. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Related Products of 18836-52-7).

(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. As a result of interactions such as these, the water solubility of amides is greater than that of corresponding hydrocarbons. These hydrogen bonds are also have an important role in the secondary structure of proteins.Related Products of 18836-52-7

SIRT1 promotes lipid metabolism and mitochondrial biogenesis in adipocytes and coordinates adipogenesis by targeting key enzymatic pathways was written by Majeed, Yasser;Halabi, Najeeb;Madani, Aisha Y.;Engelke, Rudolf;Bhagwat, Aditya M.;Abdesselem, Houari;Agha, Maha V.;Vakayil, Muneera;Courjaret, Raphael;Goswami, Neha;Hamidane, Hisham Ben;Elrayess, Mohamed A.;Rafii, Arash;Graumann, Johannes;Schmidt, Frank;Mazloum, Nayef A..

The NAD⁺-dependent deacetylase SIRT1 controls key metabolic functions by deacetylating target proteins and strategies that promote SIRT1 function such as SIRT1 overexpression or NAD+ boosters alleviate metabolic complications. We previously reported that SIRT1-depletion in 3T3-L1 preadipocytes led to C-Myc activation, adipocyte hyperplasia, and dysregulated adipocyte metabolism Here, we characterized SIRT1-depleted adipocytes by quant. mass spectrometry-based proteomics, gene-expression and biochem. analyses, and mitochondrial studies. We found that SIRT1 promoted mitochondrial biogenesis and respiration in adipocytes and expression of mols. like leptin, adiponectin, matrix metalloproteinases, lipocalin 2, and thyroid responsive protein was SIRT1-dependent. Independent validation of the proteomics dataset uncovered SIRT1-dependence of SREBF1c and PPARα signaling in adipocytes. SIRT1 promoted NMN acetyltransferase 2 (NMNAT2) expression during 3T3-L1 differentiation and constitutively repressed NMNAT1 and 3 levels. Supplementing preadipocytes with the NAD⁺ booster NMN (NMN) during differentiation increased expression levels of leptin, SIRT1, and PGC-1α and its transcriptional targets, and reduced levels of pro-fibrotic collagens (Col6A1 and Col6A3) in a SIRT1-dependent manner. Investigating the metabolic impact of the functional interaction of SIRT1 with SREBF1c and PPARα and insights into how NAD+ metabolism modulates adipocyte function could potentially lead to new avenues in developing therapeutics for obesity complications.

Alkamides from Anacyclus pyrethrum L. and their in vitro antiprotozoal activity was written by Althaus, Julia B.;Malyszek, Claudine;Kaiser, Marcel;Brun, Reto;Schmidt, Thomas J.. And the article was included in Molecules in 2017.Recommanded Product: 18836-52-7 The following contents are mentioned in the article:

In our ongoing study to evaluate the antiprotozoal activity of alkamides from Asteraceae, a dichloromethane extract from the roots of Anacyclus pyrethrum L. showed a moderate in vitro activity against the NF54 strain of Plasmodium falciparum and against Leishmania donovani (amastigotes, MHOM/ET/67/L82 strain). Seven pure alkamides and a mixture of two further alkamides were isolated by column chromatog. followed by preparative high performance liquid chromatog. The alkamides were identified by mass- and NMR-spectroscopic methods as tetradeca-2E,4E-dien-8,10-diynoic acid isobutylamide (anacycline, 1), deca-2E,4E-dienoic acid isobutylamide (pellitorine, 2), deca-2E,4E,9-trienoic acid isobutylamide (3), deca-2E,4E-dienoic acid 2-phenylethylamide (4), undeca-2E,4E-dien-8,10-diynoic acid isopentylamide (5), tetradeca-2E,4E,12Z-trien-8,10-diynoic acid isobutylamide (6), and dodeca-2E,4E-dien acid 4-hydroxy-2-phenylethylamide (7). Two compounds-undeca-2E,4E-dien-8,10-diynoic acid 2-phenylethylamide (8) and deca-2E,4E-dienoic acid 4-hydroxy-2-phenylethylamide (9) -were isolated as an inseparable mixture (1:4). Compounds 3, 4, and 5 were isolated from Anacyclus pyrethrum L. for the first time. While compounds 4 and 5 were previously known from the genus Achillea, compound 3 is a new natural product, to the best of our knowledge. All isolated alkamides were tested in vitro for antiprotozoal activity against Plasmodium falciparum, Trypanosoma brucei rhodesiense, Trypanosoma cruzi, and Leishmania donovani and for cytotoxicity against L6 rat skeletal myoblasts. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Recommanded Product: 18836-52-7).

(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. 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.Recommanded Product: 18836-52-7

Fractionation of the photochemical systems of photosynthesis. I. Chlorophyll contents and photochemical activities of particles isolated from spinach chloroplasts was written by Anderson, Jan M.;Boardman, N. K.. And the article was included in Biochimica et Biophysica Acta, Biophysics Including Photosynthesis in 1966.Reference of 730-25-6 The following contents are mentioned in the article:

Spinach chloroplasts were fragmented by incubation with digitonin and the resulting chlorophyll-containing particles separated by differential centrifugation. Particles pelleted by forces of 1000 g and 10,000 g had a lower ratio of chlorophyll a/chlorophyll b (chl a/chl b) than the chloroplasts, whereas the smaller particles which either sedimented at 50,000-144,000 g or remained in the 144,000-g supernatant had higher ratios than the chloroplasts. Chl a/chl b ratios were usually determined spectrophotometrically in 80% acetone, but essentially the same ratios were obtained after transfer of the pigments to ether or after separation of the chlorophylls by thin-layer chromatography. The small particles were inactive in the Hill reaction, either with ferricyanide, trichloroindophenol, or NADP as oxidant, but they photoreduced NADP if provided with the electron-donor couple, Na ascorbate, and dichloroindophenol, and both ferredoxin and NADP reductase. The 1000-g and 10,000-g fractions showed Hill activity, but the rate of reduction of NADP in the presence of ferredoxin and NADP reductase was lower than the rates of reduction of ferricyanide and trichloroindophenol. The particles with the high chl a/chl b ratios appear to be representative of System I (the “long wavelength” system) of photosynthesis, whereas the 1000-g and 10,000-g fractions appear to be enriched in particles representative of System 2. Chloroplasts were also fragmented by Triton X-100 and Nonidet P-40; in contrast to the digiton treatment, the particles so obtained were photochem. inactive. This study involved multiple reactions and reactants, such as N-(3,4-Dichlorophenyl)octanamide (cas: 730-25-6Reference of 730-25-6).

N-(3,4-Dichlorophenyl)octanamide (cas: 730-25-6) belongs to amides. Compared to amines, amides are very weak bases and do not have clearly defined acid–base properties in water. On the other hand, amides are much stronger bases than esters, aldehydes, and ketones. 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.Reference of 730-25-6

Mitochondria need to interact with the nucleus under homeostasis and stress to maintain cellular demands and nuclear transcriptional programs. Disrupted mitonuclear interaction is involved in many disease processes. However, the role of mitonuclear signaling regulators in endotoxin-induced acute lung injury (ALI) remains unknown. NAD (NAD⁺) is closely related to mitonuclear interaction with its central role in mitochondrial metabolism In the current study, C57BL/6J mice were administrated with lipopolysaccharide 15 mg/kg to induce endotoxin-induced ALI and investigated whether the NAD⁺ precursor NMN (NMN) could preserve mitonuclear interaction and alleviate ALI. After pretreatment with NMN for 7 days, NAD⁺ levels in the mitochondrial, nucleus, and total intracellular were significantly increased in endotoxemia mice. Moreover, supplementation of NMN alleviated lung pathol. injury, reduced ROS levels, increased MnSOD activities, mitigated mitochondrial dysfunction, ameliorated the defects in the nucleus morphol., and these cytoprotective effects were accompanied by preserving mitonuclear interaction (including mitonuclear protein imbalance and the mitochondrial unfolded protein response, UPR^mt). Furthermore, NAD⁺-mediated mitonuclear protein imbalance and UPR^mt are probably regulated by deacetylase Sirtuin1 (SIRT1).

Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields.

Nicotinamide Mononucleotide Administration Amends Protein Acetylome of Aged Mouse Liver was written by Luo, Chengting;Ding, Wenxi;Zhu, Songbiao;Chen, Yuling;Liu, Xiaohui;Deng, Haiteng. And the article was included in Cells in 2022.Reference of 1094-61-7 The following contents are mentioned in the article:

It is known that the activities of nicotine adenine dinucleotide (NAD+)-dependent deacetylase decline in the aging mouse liver, and NMN (NMN)-mediated activation of deacetylase has been shown to increase healthspans. However, age-induced changes of the acetylomic landscape and effects of NMN treatment on protein acetylation have not been reported. Here, we performed immunoprecipitation coupled with label-free quant. LC-MS/MS (IPMS) to identify the acetylome and investigate the effects of aging and NMN on liver protein acetylation. In total, 7773 acetylated peptides assigned to 1997 proteins were commonly identified from young and aged livers treated with vehicle or NMN. The major biol. processes associated with proteins exhibiting increased acetylation from aged livers were oxidation-reduction and metabolic processes. Proteins with decreased acetylation from aged livers mostly participated in transport and translation processes. Furthermore, NMN treatment inhibited the aging-related increase of acetylation on proteins regulating fatty acid β oxidation, the tricarboxylic acid (TCA) cycle and valine degradation In particular, NAD (P) transhydrogenase (NNT) was markedly hyperacetylated at K70 in aged livers, and NMN treatment decreased acetylation intensity without altering protein levels. Acetylation at cytochrome 3a25 (Cyp3a25) at K141 was also greatly increased in aged livers, and NMN treatment totally arrested this increase. Our extensive identification and anal. provide novel insight and potential targets to combat aging and aging-related functional decline. 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: 1094-61-7Reference of 1094-61-7).

((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. 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.Reference of 1094-61-7
