An increase in the production of reactive oxygen species (ROS) in mitochondria due to targeted delivery of redox active compounds may be useful in studies of modulation of cell functions by mitochondrial ROS. Recently, the mitochondria-targeted derivative of menadione (MitoK3) was synthesized. However, MitoK3 did not induce mitochondrial ROS production and lipid peroxidation while exerting significant cytotoxic action. Here we synthesized 1,4-naphthoquinone conjugated with alkyltriphenylphosphonium (SkQN) as a prototype of mitochondria-targeted prooxidant, and its redox properties, interactions with isolated mitochondria, yeast cells and various human cell lines were investigated. According to electrochem. measurements, SkQN was more active redox agent and, due to the absence of Me group in the naphthoquinone ring, more reactive as electrophile than MitoK3. SkQN (but not MitoK3) stimulated hydrogen peroxide production in isolated mitochondria. At low concentrations, SkQN stimulated state 4 respiration in mitochondria, decreased membrane potential, and blocked ATP synthesis, being more efficient uncoupler of oxidative phosphorylation than MitoK3. In yeast cells, SkQN decreased cell viability and induced oxidative stress and mitochondrial fragmentation. SkQN killed various tumor cells much more efficiently than MitoK3. Since many tumors are characterized by increased oxidative stress, the use of new mitochondria-targeted prooxidants may be a promising strategy for anticancer therapy.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Electroanalysis called Quaternary Ammonium Based Carboxyl Functionalized Ionic Liquid for Covalent Immobilization of Horseradish Peroxidase and Development of Electrochemical Hydrogen Peroxide Biosensor, Author is Murphy, Manoharan; Theyagarajan, K.; Thenmozhi, Kathavarayan; Senthilkumar, Sellappan, which mentions a compound: 2834-05-1, SMILESS is O=C(O)CCCCCCCCCCBr, Molecular C11H21BrO2, Related Products of 2834-05-1.

A novel electrochem. biosensor was developed using a judiciously designed platform for the rapid and accurate determination of hydrogen peroxide (H2O2). The horseradish peroxidase (HRP) based biosensor was constructed by covalent anchoring of the enzyme to a newly synthesized quaternary ammonium-based carboxyl functionalized ionic liquid (TBA-COOH-IL) immobilized on a multiwalled carbon nanotube deposited glassy carbon electrode (MWCNT/GCE). A stable amide bond is formed between HRP enzyme and IL by utilizing the terminal -NH2 of HRP and -COOH groups of TBA-COOH-IL, while the pi-pi stacking holds the TBA-COOH-IL firmly on the MWCNT/GCE and forms HRP/TBA-COOH-IL/MWCNT/GCE. Thus fabricated HRP/TBA-COOH-IL/MWCNT/GCE displayed a well-resolved redox peak at a formal potential (E°’) of -0.32 V, which corresponds to the concealed FeIII/FeII redox center of the immobilized HRP enzyme. Further, the developed biosensor was employed for the electrocatalytic determination of H2O2 in static and dynamic conditions, which showed a wide linear range from 0.02 to 4.30 mM with a high sensitivity and low detection limit of 160.6μA mM-1 cm-2 and 6μM, resp. The excellent performance of the fabricated biosensor is attributed to the stable covalent anchoring of freely water-soluble enzyme on the newly designed, highly conducting and biocompatible platform. Furthermore, the fabricated biosensor exhibited good reproducibility with an extended long-term stability.

The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 11-Bromoundecanoic acid( cas:2834-05-1 ) is researched.Electric Literature of C11H21BrO2.Pradhan, Tapas R.; Lee, Hae Eun; Gonzalez-Montiel, Gisela A.; Cheong, Paul Ha-Yeon; Park, Jin Kyoon published the article 《Highly Chemoselective Esterification from O-Aminoallylation of Carboxylic Acids: Metal- and Reagent-Free Hydrocarboxylation of Allenamides》 about this compound( cas:2834-05-1 ) in Chemistry – A European Journal. Keywords: trans acyloxyenamide preparation regioselective chemoselective diastereoselective green chem; allenamide carboxylic acid hydrocarboxylation aminoallylation; (E)-enamides; Brønsted acid; carboxylic acids; linear selective; metal-free. Let’s learn more about this compound (cas:2834-05-1).

Metal-free hydrocarboxylation of allenamides RCH=C=CH2 (R = N-benzyl(4-methylbenzene)sulfonamide, (methoxycarbonyl)(naphthalen-1-yl)aminyl, 2-oxo-1,3-oxazolidin-3-yl, etc.) with various functionalized carboxylic acids R1C(O)OH (R1 = Me, Ph, 1-(4-nitrophenyl)ethyl, 6-chloroimidazo[1,2-a]pyridin-3-yl, etc.) was achieved with complete regio- and stereocontrol (>49:1). This environmentally compatible transformation affords γ-acyloxyenamides RCH=CHCH2OC(O)R1 with exclusive E-selectivity. Electron rich, electron poor, aliphatic, aryl, and heterocyclic carboxylic acids all gave excellent yields (avg. 89%, 47 examples). The synthetic potential of this transformation in the late-stage modification of complex natural carboxylic acids and simple modification of the products to three-carbon synthons with ample opportunity for further diversification were demonstrated. DFT studies revealed that the reaction occurs in a stepwise manner through the intermediacy of a conjugated iminium species, which is rapidly captured by the carboxylate ion, resulting in the observed linear selectivity.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 11-Bromoundecanoic acid(SMILESS: O=C(O)CCCCCCCCCCBr,cas:2834-05-1) is researched.Recommanded Product: 580-34-7. The article 《Carbon supported hybrid catalysts for controlled product selectivity in the hydrosilylation of alkynes》 in relation to this compound, is published in Catalysis Science & Technology. Let’s take a look at the latest research on this compound (cas:2834-05-1).

A series of Rh- and Ir-hybrid catalysts with varying tether lengths has been prepared by immobilization of RhI, RhIII and IrIII complexes on carbon black via radical grafting. The performance of the different catalysts was assessed for the hydrosilylation of phenylacetylene with Et3SiH. The efficiency of the catalysts was dependent on the length of the tethers to the surface. The RhIII- and IrIII hybrids afforded the β(Z)-vinylsilanes, as observed for the analogous homogeneous RhIII catalyst. No distinct product selectivity was observed when using the homogeneous RhI precursors as catalysts. However, on using the RhIII hybrid catalysts derived from the RhI precursors to promote hydrosilylation, the major products were the α-vinylsilanes and the origin of the difference in reactivity was found to be a chem. modification of the catalysts during immobilization. Substrate scope is demonstrated for a number of alkynes, and feasible mechanisms supported by DFT calculations are proposed.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Adsorption of phenylalanine-rich sequence-defined oligomers onto Kevlar fibers for fiber-reinforced polyolefin composite materials.Reference of 11-Bromoundecanoic acid.

Oligomers comprising four or sixteen phenylalanine residues with regularly intercalated aliphatic chains of different lengths prepared by solid-phase synthesis exhibit sufficient thermal stability to be used as interfacial agents and processed for the preparation of poly(propylene-co-ethylene)-based composite materials. The investigation of their adsorption on Kevlar fibers by SEM is difficult due to the surface heterogeneity of the bare Kevlar fibers. However, oligomers with four successive phenylalanine residues have been clearly observed suggesting their better adsorption on the fiber. The quantification of those oligomers adsorbed on the fibers performed gravimetrically on pellets of fibers has however revealed no significant impact of the length of the aliphatic chain.

The article 《Shaping Liquid Crystals with Gold Nanoparticles: Helical Assemblies with Tunable and Hierarchical Structures Via Thin-Film Cooperative Interactions》 in relation to this compound, is published in Advanced Materials (Weinheim, Germany). Let’s take a look at the latest research on this compound (cas:2834-05-1).

The availability of helical assemblies of plasmonic nanoparticles with precisely controlled and tunable structures can play a key role in the future development of chiral plasmonics and metamaterials. Here, a strategy to efficiently yield helical structures based on the cooperative interactions of liquid crystals and gold nanoparticles in thin films is developed. These nanocomposites exhibit exceptional long-range hierarchical order across length scales, which results from the growth mechanism of nanoparticle-coated twisted nanoribbons and their ability to form organized bundles. The helical assembly formation is governed by the presence of rationally functionalized nanoparticles. Importantly, the thickness of the achieved nanocomposites can be reversibly reconfigured owing to the polymorphic nature of the liquid crystal. The versatility of the proposed approach is demonstrated by preparing helixes assembled from nanoparticles of different geometries and dimensions (spherical and rod-like). The described strategy may become an enabling technol. for structuring nanoparticle assemblies with high precision and fabricating optically active materials.

Application of 2834-05-1. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Syzygium aromaticum (clove) essential oil: An alternative for the sanitization of citrus fruit in packinghouses.

Citrus canker is a quarentenary disease caused by Xanthomonas citri subsp. citri (X. citri). Thus, sanitization of fresh fruit is a necessary measure before any com. activity. Therefore, we evaluated the clove essential oil (CEO), as an alternative sanitizer for the disinfection of citrus fruit in packinghouses. Tests in vitro and in vivo were carried out to determine the cell inhibitory concentration and to verify the efficacy of the oil for the disinfection of citrus fruits. In in vitro tests, CEO was able to inhibit X. citri when used at 0.75% (volume/volume). In experiments that simulate the sanitization process used in packinghouses, 5% CEO was as effective as the recommended sanitization product based on sodium hypochlorite. GC-MS results showed a high presence of eugenol derivatives as the major compounds of CEO. All results proved that CEO is a potential sanitizer that could be used as an alternative to sodium hypochlorite. Novelty impact statement : Exptl. evidence shows that the clove essential oil (CEO) has the same sanitization efficacy as sodium hypochlorite, which makes of CEO an alternative sanitizer for the decontamination of citrus fruits to be exported to the European Union. CEO is a safer and more sustainable sanitizer for the postharvest disinfection of citrus fruit.
