Ethnopharmacological relevance: Zanthoxylum armatum DC (Rutaceae) containing flavonoids, alkaloids, coumarins, lignans, amides and terpenoid is well-known for its curative properties against various ailments including cancer. In the current research, phytochemicals present in the methanolic extract of Zanthoxylum armatum bark (MeZb) were characterized by LC-MS/MS analysis and chemotherapeutic potential of this extract was determined on DMBA-induced female Sprague Dawley rats. Materials and methods: A simple and fast high-performance liquid chromatography-mass spectroscopy (LC-MS/MS) of MeZb was established followed by in-vitro antioxidant assays. This was followed by in-silico docking analysis as well as cytotoxicity assessment. Successively in-vivo study of MeZb was performed in DMBA-induced Sprague Dawley rats possessing breast cancer along with detailed molecular biology studies involving immunofluorescence, RT-qPCR and Western blot analysis. Results: LC-MS/MS investigation revealed the presence of compounds belonging to flavonoid, alkaloid and glycoside groups. MeZb revealed potential antioxidant activity in in-vitro antioxidant assays and strong binding energy of identified compounds was seen from the in-silico study with both HO1 and Keap1 receptor. Furthermore, the antioxidant action of MeZb was proven from the in-vivo analysis of antioxidant marker enzymes (lipid peroxidation, enzymic and non-enzymic antioxidants). This study also revealed upregulation of protective Nrf-2 following downregulation of Keap1 after MeZb treatment with respect to untreated cancerous rats. Conclusion: These results exhibited anti-breast-cancer potential of MeZb through Nrf2-Keap1 pathway which may be due to the flavonoids, alkaloids and glycosides present in it.

It is crucial to develop highly sensitive and selective probes toward hydrazine because it is a class of highly toxic and pollutant compound. Herein, using fracture of carbon carbon double bond and dissociation of amide by hydrazine, a novel off-on fluorescent probe was developed for hydrazine. The probe can quantitatively detect hydrazine in concentration range from 0 to 20 mu M with the LOD of 140 nM. Further, it displayed excellent selectivity and anti-interference ability over many neutral molecules, metal ions, anions, and biological species. The ability to target lysosome and the response of hydrazine to this probe in a living cell was successfully tracked via fluorescence imaging. (C) 2017 Elsevier Ltd. All rights reserved.

In search of more potent new antitubercular agents, a library of novel piperazine tethered dimeric 1,2,3-triazoles were designed by assembling 1,2,3-triazoles and piperazine in a single molecular architectural framework. The titled compounds (3a-m) were synthesized by 1,3-dipolar cycloaddition of 1,4-di(prop-2-yn-1-yl)piperazine (1) and various azides (2a-m) using click chemistry approach with good yields. All the synthesized compounds (3a-m) have been screened for their in vitro antitubercular, antifungal and antioxidant activities against their respective strains. Among them, 3b, 3d, and 3i have revealed promising antitubercular activity against Mycobacterium tuberculosis (Mtb) H37Rv with MIC 12.5 mu g/mL. Molecular docking results provided well-clustered solutions to the mode of binding for these molecules into the active site of Mtb enoyl reductase (InhA). In addition to this, most of synthesized compounds were found to have potential antifungal as well as antioxidant activity.

Soluble epoxide hydrolase (sEH) enzyme plays an important role in the metabolism of endogenous chemical mediators, epoxyeicosatrienoic acids, which are involved in the regulation of blood pressure and inflammation. According to the pharmacophoric model suggested for sEH inhibitors, some new amide-based derivatives of 3-phenylglutaric acid were designed, synthesized and biologically evaluated. Docking study illustrated that the amide group as a primary pharmacophore had a suitable distance from the three amino acids of Tyr383, Tyr466 and Asp335 for effective hydrogen binding. Most of the compounds showed moderate to high sEH inhibitory activities in in vitro test in comparison with 12-(3-Adamantan-1-yl-ureido)-dodecanoic acid, as a potent urea-based sEH inhibitor. Compound 6o with phenethyl in R position exhibited the highest activity with IC50 value of 0.5 nM. Graphic abstract In this study, some new amide-based derivatives of 3-phenylglutaric acid were designed, synthesized and biologically evaluated. Most of the synthesized compounds provided nanomolar range inhibition against sEH enzyme. The best observed IC50 value was 0.5 nM. Incorporating a carboxylic moiety into these structures by forming carboxylate salts would increase the solubility and improving physicochemical properties. [GRAPHICS] .

A., once mentioned the application of 593-81-7, Recommanded Product: Trimethylamine hydrochloride, Name is Trimethylamine hydrochloride, molecular formula is C3H10ClN, molecular weight is 95.5712, MDL number is MFCD00012478, category is amides-buliding-blocks. Now introduce a scientific discovery about this category.

Hydrogen deuterium exchange mass spectrometry (HDX MS) reports on the conformational landscape of proteins by monitoring the exchange between backbone amide hydrogen atoms and deuterium in the solvent. To maintain the label for analysis, quench conditions of low temperature and pH are required during the chromatography step performed after protease digestion but before mass spectrometry. Separation at 0 degrees C is often chosen as this is the temperature where the most deuterium can be recovered without freezing of the typical water and acetonitrile mobile phases. Several recent reports of separations at subzero Celsius emphasize the promise for retaining more deuterium and using a much longer chromatographic gradient or direct infusion time. Here we present the construction and validation of a modified Waters nanoACQUITY HDX manager with a third temperature-controlled zone for peptide separations at subzero temperatures. A new Peltier-cooled door replaces the door of a traditional main cooling chamber and the separations and trapping column are routed through the door housing. To prevent freezing, 35% methanol is introduced post online digestion. No new pumps are required and online digestion is performed as in the past. Subzero separations, using conventional HPLC column geometry of 3 mu m particles in a 1 x 50 mm column, did not result in major changes to chromatographic efficiency when lowering the temperature from 0 to -20 degrees C. There were significant increases in deuterium recovery for both model peptides and biologically relevant protein systems. Given the higher levels of deuterium recovery, expanded gradient programs can be used to allow for higher chromatographic peak capacity and therefore the analysis of larger and more complex,proteins and systems.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. Category: amides-buliding-blocks, 3144-09-0, Name is Methylsulfonamide, SMILES is CS(=O)(N)=O, in an article , author is Chen, Xuebin, once mentioned of 3144-09-0.

Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) has become the world’s leading killer disease due to a single infectious agent which survives in the host macrophage for the indefinite period. Hence, it is necessary to enhance the efficacy of the clinically existing antitubercular agents or to discover new anti antitubercular agents. Here, we report the synthesis, characterization and antimycobacterial evaluation of protein-drug conjugates. A carrier protein, Transferrin (Tf) was covalently conjugated to isoniazid (INH) utilizing hydrazone and amide linkers. The purity of the reactions was confirmed by SDS-PAGE while conjugation was confirmed by UV-visible spectrophotometry, MALDI-TOF analysis, and FFIR spectrophotometry. The in vitro antitubercular assay result showed that the inhibitory activity of the parent drug was conserved in both the conjugates. The conjugates were effective against intracellular Mtb H37Rv and were devoid of cytotoxic effect at therapeutic concentration. (C) 2019 Elsevier Masson SAS. All rights reserved.

A family of calix[4]arenes with variation in steric crowding at the upper rim and incorporating pyridine and amide moieties at two of the four OH groups located in the lower rim have been synthesized and their performance as sensors for metal ions has been investigated. Two of the compounds exhibited selective interaction with Cu2+ ions with sharp colour change, observed by the naked eye. Spectroscopic and computational studies revealed that two of the compounds form 1 : 2 complexes, in which one of the Cu2+ ions interacts strongly with the phenolic OH, resulting in a colour change due to strong absorption (ICT) in the visible region. For the third compound, the Cu2+ ions coordinate with the pyridine and amide nitrogen atoms, and the Cu2+ ion could not enter inside to interact with the OH group due to restricted flexibility at the lower rim because of the bulky groups at the upper rim. The Cu2+ complexes thus formed have been used for sensing of amino acids and interestingly, one of the complexes exhibits interactions selectively with cysteine out of eighteen amino acids tested with a sharp colour change in aqueous media. The formation of the Cu2+-cysteine complex is confirmed from mass data, and the surface morphology of the complex before and after the addition of cysteine is investigated by SEM study.

Aims: Bacterial pathogens such as Pseudomonas aeruginosa and Burkholderia pseudomallei are intrinsically resistant to many classes of antibiotics. This is not only due to the poor permeability of their outer membrane but also because of expression of multiple efflux pumps. A promising strategy to minimize the efflux of drugs by these pumps is the use of efflux pump inhibitors (EPIs). In this study, the potential of caffeic acid derivatives as EPIs in P. aeruginosa and B. pseudomallei were evaluated. Methodology and results: The potential of caffeic acid and its derivatives, i.e. chlorogenic acid, caffeic acid phenethyl ester (CAPE) and caffeic acid phenethyl amide (CAPA) to act as EPIs in P. aeruginosa and B. pseudomallei were assessed using the ethidium bromide (EtBr) accumulation and minimum inhibitory concentration (MIC) validation assays. Among the four test compounds, CAPE was found to significantly increased intracellular accumulation of EtBr in both P. aeruginosa and B. pseudomallei. An increase of 21.4% and 16.8% in cell fluorescence, over a 5-min time frame was observed in P. aeruginosa and B. pseudomallei respectively. Combination of CAPE with kanamycin significantly reduced MICs of this aminoglycoside by a factor of 8-fold in P. aeruginosa and 2-fold in B. pseudomallei. Combination of CAPE with gentamicin also led to a reduction of 4-fold MIC value of this antibiotic in B. pseudomallei. Conclusion, significance and impact of study: The in-vitro results suggest that CAPE has the potential to act as an EPI in P. aeruginosa and B. pseudomallei, thus improving the efficacy of aminoglycosides as antimicrobial agents.

The worldwide plastic waste production is steadily increasing, since the use of polymeric materials continues to rise. One area of particular high plastic consumption is food packaging. Flexible and rigid packaging films are typically made from petrochemical-sourced polymers, which are utilized because of their low cost, ductility, melt-processability, and gas barrier properties, but a major downside is their inability to biodegrade in a reasonable time. Packaging-relevant properties of nanocomposites based on polyester-amides (PEAs) are reported, which are chosen on account of their tunable crystallinity, biobased starting materials, and biodegradability. These polymers are synthesized via melt polycondensation of a building block made from caprolactone and 1,4-diaminobutane, with the addition of 1,4-butanediol and dimethyl adipate. The fraction of the amide segment is varied between 25 and 75 mol%. The oxygen transmission rate (O2TR) drops upon increasing the amide content from 1.6 x 10(5) to 2.9 x 10(-4) cm(3) m(-2) d(-1) on account of increasing crystallinity. In order to improve the gas barrier properties further, nanocomposites of the PEAs and 1-10 wt% cellulose nanocrystals (CNCs) are prepared. These nanocomposites have indeed lower O2TR values than the neat PEAs, with reductions of as much as 50% for a CNC content of 10 wt%.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 6313-33-3, Name is Formimidamide hydrochloride, molecular formula is CH5ClN2, belongs to amides-buliding-blocks compound. In a document, author is Kim, Kue-Ho, introduce the new discover, COA of Formula: https://www.ambeed.com/products/6313-33-3.html.

Alternately N-alkylated aromatic amides such as 1-3 bearing various side chains were designed and synthesized as novel helical foldamers. The CD spectra of oligomers with chiral side chains showed a positive Cotton effect, which indicates that these oligomers take helical conformations in solution. The CD intensity gradually increased with increasing chain length, and pentamer 3d showed remarkably strong CD signals in chloroform. The absorption maxima of the UV spectra were increasingly red shifted with increasing chain length, in contrast to the case of poly(p-N-alkylbenzamide)s. Structure optimization of the oligomers based on the crystal structure of la as the monomer unit supported the formation of helical structure with a large cavity and also suggested intramolecular hydrogen bond formation between secondary amides. The results of calculation were consistent with the observed spectroscopic features.
