With increasing ecological and environmental concerns because of the extensive use petroleum-based products, natural resources for preparation functional materials is great public value. Cellulose introduced as an ideal promising biomaterial widespread application which obtained from biobased sources such plants, biomass, or bacteria, relying on efficient, scalable, facile methods. Generally, sulfation, silylation, esterification, phosphorylation, etherification, oxidation are common...

Nanotechnology and nanoscience hold great promise for many multidisciplinary applications, including catalysis where gold nanoparticles (GNPs) are considered "safer environmentally benign" on account of the fact that they relatively nontoxic efficient pivotal applications in natural-product synthesis, organic reactions, pharmaceutical industry, medicinal chemistry. Since physicochemical characteristics GNPs pertain to their shape, size, composition, surface modification, these features...

Abstract Branched architectures with asymmetric polymeric arms provide an advantageous platform for the construction of tailored nanocarriers therapeutic interventions. Simple and adaptable synthetic methodologies to amphiphilic miktoarm star polymers have been developed in which spatial location reactive oxygen species (ROS) glutathione (GSH) responsive entities is articulated be on corona shell surface or inside core. The design such facilitated through versatile building blocks selected...

MCRs as privileged and practical synthetic route, have been deployed for preparation of COFs. Subsequently, proficient COFs robust catalysts employed the sustainable MCRs.

A ZnCl2-catalyzed regio- and diastereoselective one-pot sequential Knoevenagel condensation/1,3-dipolar cycloaddition reaction of CH acids (oxindole, 1,3-indandione, 3H-pyrazol-3-one), aldehydes, dibromoformaldoxime has been established. The method allows the synthesis diversely functionalized spiroisoxazolines in good isolated yields under mild conditions. Moreover, preparation spiroindene-isoxazole-1,3-diones containing benzoimidazole or benzothiazole moieties as new ligands for...

The possibility of formation complexes between glycine and boron doped C60 (C59B) fullerene is investigated compared with that by using the density functional theory calculations. It has been found binding to C59B generated most stable via its carbonyl oxygen active site, a energy −37.89kcal/mol, while molecule prefers bind pure cage amino nitrogen consistent recent experimental theoretical studies. We have also tested stability Gly-C59B complex ab initio molecular dynamics simulation,...

Abstract The deployment of multicomponent reactions (MCRs), defined as containing three or more reactants, not only enjoys pot, atom, and step‐economy in the synthesis novel complex molecules but also aligns with sustainable chemistry principles a green symphony. Generally, components lead to complexity, are taken an extreme ‘‘higher‐order’’ MCRs, where six even react one‐pot, have been developed, although they remain scarce compared their 3, 4 5‐component relatives. On this topic, rich...

In order to investigate the effects of foliar application amino acid and calcium chelate on "Golden Delicious" "Granny smith" apple trees, a randomized complete block design with four repetitions was conducted.Apple trees were sprayed (0, 2, 4 mg L -1 ) their combination.Fruit weight, fruit firmness, total soluble solids, titretable acidity content fruits determined.All applied treatments significantly increased quality quantity traits compared control in both cultivars.The combination...

An architectural polymer containing hydrophobic isoxazole-based dendron and hydrophilic polyethylene glycol linear tail is prepared by a combination of the robust ZnCl2 catalyzed alkyne-nitrile oxide 1,3-dipolar cycloaddition esterification chemistry. This water soluble amphiphilic telodendrimer acts as macromolecular biologically active agent shows concentration dependent reduction glioblastoma (U251) cell survival.

Background: Medicinal plants are considered as modern resources for producing agents that could act alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim the present study was evaluate chemical composition and antibacterial activity essential oil Pistacia khinjuk (combined with dominance γ-terpinene) against P. aeruginosa B. subtilis. Materials Methods: identified using gas chromatography coupled mass spectrometer detector (GC-MS). As a screen test detect property...

T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety alcohols. Alcohols are oxidized in situ aldehydes under conditions, which undergo three-component reaction with N,N'-dimethylbarbituric acid various isocyanides afford good yields.
