The plasticizing effect of N,N-diethyl-3-methylbenzamide (DEET) on poly(l-lactic acid) (PLLA) is analyzed and discussed in this manuscript. DEET is the key active ingredient in many commercial mosquito-repellent formulations, and is also an environment-friendly compound, which well matches the b...

Nano-α-Fe2O3 can accelerate the degradation of diethyl phthalate ester (DEP) in the presence of citric acid under UV (300–400 nm) irradiation, but the underlying mechanism remains unclear. In this study, based on ultraviolet photoelectron spectra (UPS) and density functional theory (DFT) analy...

Diethyl phthalate ester (DEP) can be degraded in Fe3+-UV- aliphatic/phenolic carboxyl acids systems, and the degradation can be significantly influenced by different physical chemical properties of the organic acids. In this study, a density function theory (DFT) approach combined with multiline...

The critical temperatures and pressures of diethyl esters of dicarboxylic acids C2H5OOC(CH2)n-2COOC2H5 with straight alkyl chains and n = 3, 4, 6 have been measured. These data and the results of the previous measurements have been analyzed and the recommended critical properties of dicarboxylic...

2-Hydroxyheptanal (2-HH) is one of the major aldehydes derived from peroxidation of polyunsaturated fatty acids. In the present study, to obtain an insight into the contributions of 2-HH to protein modifications during lipid peroxidation, a lysine-containing dipeptide, Nα-hippuryllysine (N-benz...

2-Hydroxyheptanal (2-HH) is one of the reactive aldehyde species generated during the peroxidation of n−6 polyunsaturated fatty acids, such as linoleic and arachidonic acids. Analogous to the Maillard reaction of reducing sugars, 2-HH readily reacts with lysine ε-amino groups. In the present st...

The degradation of four dimeric lignin model compounds by meso-tetra(2,6-dichloro-3-sulfonatophenyl)porphyrin iron chloride (TDCSPPFeCI) (2) are reported. 4-Ethoxy-3-methoxyphenylglycerol-β-guaiacyl ether (3) (a β-0-4 dimer) was cleaved to give 4-ethoxy-3-methoxybenzaldehyde (4) and guaiacol (...

Herein, Nitrogen functionalized graphene oxide (N-f-GrO) has been synthesized using the sonochemical method. 2-Aminopyrimidine (APD) was used as a precursor for covalent functionalization with graphene oxide [f-(APD)GrO] as N-f-GrO which was ascertained with XPS. The involvement of arylamine gro...

Extended studies in the 4-aryl-pyrido[1,2-c]pyrimidine group resulted in 27 new compounds (10.1-10.27), 5,6,7,8-tetrahydropyrido[1,2-c]pyrimidine derivatives. In vitro tests (RBA) were carried out for 10.1-10.27 compounds in order to determine their affinity to 5-HT1A receptor and SERT protein. ...

The X-ray diffraction analysis of N-o-nitrophenyl-2,3,4,6-tetra-O-acetyl-β-d-glucopyranosylamine (1), N-m-nitrophenyl-2,3,4,6-tetra-O-acetyl-β-d-glucopyranosylamines, N-p-nitrophenyl-2,3,4,6-tetra-O-acetyl-β-d-glucopyranosylamines, and their N-acetyl derivatives was performed. The sugar moiet...

Structural analyses of four compounds (phenyl 2,3,4,6-tetra-O-acetyl-β-d-galactopyranoside (1), phenyl β-d-galactopyranoside (2), phenyl 2,3,4,6-tetra-O-acetyl-α-d-galactopyranoside (3) and phenyl α-d-galactopyranoside (4)) have been performed using solid-state 13C MAS NMR spectroscopy and t...

γ-Oryzanol is an important phytochemical used in pharmaceutical, alimentary and cosmetic preparations. The present article, for the first time, discloses the performances of NP-HPLC in separating γ-oryzanol components and develops a validated method for its routine quantification. The analysis...

Coumaric acid and its derivatives are known to inhibit UV-induced melanogenesis, skin erythema, angiogenesis, platelet accumulation and osteoclastogenesis besides regulation of bone formation, anti-oxidant and anti-microbial activities. The present study is a novel piece of work in which the syn...

The fungus Alternaria alternata can cause food contamination by black spot rot and food safety issues due to the production of mycotoxins. In particular, A. alternata can infect many fresh fruits and vegetables and lead to considerable postharvest decay during storage and processing. The use of ...

BackgroundIt is well known that medicinal plants and their products are relevant candidates for the treatment of inflammatory conditions. Ethyl p-coumarate is a phenylpropanoid that has similar structure to others anti-inflammatory and antioxidant substances. However, these activities have never...

2,3,4,6-Tetra-O-acetyl-β-D-glucopyranosyl- and 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-β-D-glucopyranosyl azides were transformed into the corresponding per-O-acetylated N-(β-D-glycopyranosyl) amides via a PMe3 mediated Staudinger protocol (generation of N-(β-D-glycopyranosyl)imino-trimethylp...
