Benzoic acid is a typical substrate for monocarboxylic acid transporters (MCTs), and easily taken up from the apical membranes of Caco-2 cells by MCTs. However, some benzoic acid derivatives were sparingly taken up by Caco-2 cells. To elucidate the mechanism of lower uptake of the derivatives, w...

In the present study, we confirm that 2,4-dichlorophenoxyacetic acid (2,4-D) oxygenase from Sphingomonas agrestis 58-1 belongs to the family of Rieske non-heme iron aromatic ring-hydroxylating oxygenases, which comprise a core enzyme (oxygenase), ferredoxin, and oxidoreductase. It has previously...

The cellular uptake mechanism of 4-chloro-2-methylphenoxyacetic acid (MCPA), a phenoxyacetic acid derivative, was investigated using Caco-2 epithelial cells. The cells were incubated with 50 μM MCPA at pH 6.0 and 37 °C, and the uptake of MCPA from the apical membranes was measured. The uptake ...

The initial degradation mechanisms of OH and 4-chloro-2-methylphenoxyacetic acid (MCPA) including molecular form and anionic form are studied at the MPWB1K/6-311+G(3df, 2p)//MPWB1K/6-31+G(d, p) level. Possible reaction pathways of H-atom abstraction and OH addition are considered in detail. By r...

4-Chloro-2-methylphenoxyacetic acid (MCPA) is a selective systemic herbicide which is absorbed by leaves and roots. MCPA esters are preferred due to their low water solubility and environmental friendliness. Esterification of MCPA with n-butanol was investigated as a model reaction using immobil...

The optimized molecular structure, vibrational wavenumbers, corresponding vibrational assignments of 5-ethylsulphonyl-2-(p-aminophenyl)benzoxazole have been investigated experimentally and theoretically based on density functional theory. Synthesis and antibacterial and antimicrobial activities ...

The optimized molecular structure, vibrational wavenumbers, corresponding vibrational assignments of 2-[4-(4-phenylbutanamido)phenyl]-5-ethylsulphonyl-benzoxazole have been investigated experimentally and theoretically using Gaussian09 software. The wavenumbers were assigned by potential energy ...

A mixed nano-metal oxides of Cu-Ni-Co has been synthesized. Several characterization techniques (EDS, XRD, TEM, and SEM) have been used to provide insight into the nature and structure of the catalyst. The size of this mixed metal oxide is 22 nm. The SEM images indicate that the sample with sphe...

A DCP promoted metal-free, regio and stereoselective S-methylation/phenylation of allyl halides using sulfoxides as sulfenylating agent is described. A variety of multifunctional allyl halides underwent S-methylation and S-phenylation by using dimethyl sulfoxide (DMSO) and diphenyl sulfoxide (DP...

The yeast, Cryptococcus sp. MTCC 5455 was grown on various agro-industrial residues for the production of lipase. A maximum lipase activity of 753 ± 19 U g dry substrate−1 (U gds−1) and a biomass of 103 ± 5 mg gds−1 was obtained at 25 °C and 120 h using cottonseed oil cake with 71% moisture c...

The protic ionic liquids (PILs) di-[bis(2-hydroxyethyl)ammonium] adipate (DAd), bis(2-hydroxyethyl)ammonium salicylate (DSa) and bis(2-hydroxyethyl)ammonium oleate (DO), composed of organic anions and cations, were selected for pin-on-disc tribological tests as lubricants of OFHC copper discs sl...

In this work, clay polymer nanocomposites (CPN) with simultaneous dispersion of graphene and organomontmorillonites (OMt) in a poly (butylene adipate-co-terephthalate) (PBAT) biodegradable matrix were prepared, using the melt-blending technique. Two different OMt were used non polar Cloisite15A ...

Good quality single crystals of Piperazinium adipate were grown from aqueous solution at room temperature by slow solvent evaporation method. The crystal belongs to triclinic crystal system with centrosymmetric space group P1¯. Various functional groups present in the title compound were identi...

We investigated changes in soil microbiota associated with the degradation of poly(butylene adipate-co-terephthalate) (PBAT) film at 30 °C using a polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) method. The analysis revealed that fungal flora in soil in the vicinity...

The use of biodegradable plastic films made of poly(butylene adipate-co-terephthalate) (PBAT) to improve crop production has been proposed. Because the film after use is expected to be degraded on site, it is important to understand the biodegradation mechanism of PBAT in aerobic and mild temper...

A novel nanocomposite of silver/titanium dioxide/chitosan adipate (Ag/TiO2/CS) was developed through photochemical reduction using a chitosan adipate template. Chitosan served as a reducing agent anchoring the metal ions through Ag–N coordination bonds and electrostatic attractions, thus stabil...

Cellulose nanocrystals (CNCs) are nature-resourced nanoparticles and have been widely used to improve performance of biodegradable polyesters. Two types of CNCs respectively prepared by sulphuric acid hydrolysis (aCNCs) and ammonium persulfate oxidation (oCNCs) processes were incorporated into p...

Di(2-ethylhexyl) adipate (DEHA) is a plasticizer and phthalate substitute used in various consumer products. Relevant population exposures have to be assumed.
