Al Otaibi, Ahmed published the artcileA methanol and protic ionic liquid Ugi multicomponent reaction path to cytotoxic α-phenylacetamido amides, Computed Properties of 86-51-1, the main research area is protic ionic liquid alpha phenylacetamido amides anticancer.

The Ugi four component reaction of an aldehyde, amine, isocyanide and an ethanoic acid was effected smoothly in protic ionic liquids ethylammonium nitrate (EAN) and propylammonium nitrate (PAN) to afford analogs of α-phenylacetamido amides in good to excellent isolated yields. The corresponding reactions in [BMIM][PF6] and the protic ionic liquid ethanolammonium nitrate (ETAN) failed. Microwave irradiation in EAN facilitated rapid access to three focused libraries, based on the parent isocyanide: cyclohexyl isocyanide, benzyl isocyanide and Et isocyanoacetate. Anal. of the structure activity relationship data suggested the presence of a bulky moiety originating from the isocyanide (cyclohexyl and benzyl) enhanced cytotoxicity. Removal of the acetylenic H-atom from the ethanoic acid moiety was detrimental to cytotoxicity. The most active analogs produced, N-(2-cyclohexylamino)-1-(4-methoxyphenyl)-2-oxoethyl-N-(3,5-dimethoxyphenyl)propiolamide, returned average GI50 values of ≤1 μM across the cancer cell lines evaluated. Combined, these data suggest that analogs of this nature are interesting potential anti-cancer development leads.

A 4-fold interpenetrated diamond-like topol. metal-organic framework (MOF), Ni(pybz)2 [pybz = 4-(4-pyridyl)benzoate] was successfully synthesized and fully characterized. This MOF can serve as coating material in gas chromatog. capillary column for the separation of some low b.p. essential oils. The prepared columns have good recognition ability and excellent selectivity toward organic compounds, including alcs., aldehydes, ketones, carboxylic acid, ethers, ester, and amines. The strained metal sites, van der Waals interactions, C-H···π attraction, and weak nonclassical hydrogen bond contribute to the recognition and selectivity of prepared columns. The grand canonical Monte Carlo technique was used to simulate the interactions of the adsorbates with MOF. The calculated van der Waals energies agree with the results of gas chromatog. separation

Chen, Jiangyan published the artcileApplication of UHPLC-Q-TOF MS based untargeted metabolomics reveals variation and correlation amongst different tissues of Eucommia ulmoides Oliver, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is metabolomic variation Eucommia liquid chromatog mass spectrometry.

The biol. function of Eucommia ulmoides Oliver (EU) is related to its metabolites. However, due to the complexity of distribution of metabolites in different tissues, currently, the comprehensive information anal. on metabolome of EU has been limited. In this study, we analyzed the components of leaves, seeds and barks of EU by using ultra high-performance liquid chromatog.-tandem time-of-flight mass spectrometer (UHPLC-Q-TOF MS) untargeted metabolomics before 2373 metabolites were identified in total. By using Principal Component Anal. (PCA), Partial Least Square Discriminant Anal. (PLS-DA) and other multivariate statistical anal. methods, there were 116 metabolites expressing differently in all samples. The result showed that the metabolic composition of leaves was similar to that of barks and there still existed significant differences amongst different tissues in HCA anal. Besides, the heatmap of differential metabolites also showed the higher concentrations of organic acids and derivatives, lipids and lipid-like mols. in seeds compared to leaves and barks. Furthermore, we detected 13,456 metabolites-metabolites correlations and determined 1098 metabolic pairs which resulted in significant correlation by Pearsons correlation anal. At last, all detected metabolites were annotated in KEGG and 966 of them had KEGG ID. After enrichment anal., 311 metabolites were mapped in 168 pathways and 26 of these pathways had apparent influence in the metabolic differences amongst different parts of EU. This work provides the first comprehensive metabolomic of EU, which will provide theor. basis for the separation and identification of medicinal activities of EU and potentially help advance studies in EU metabolic engineering.

Navedo, Juan G. published the artcileAssessing the effects of human activities on the foraging opportunities of migratory shorebirds in Austral high-latitude bays, Category: isoquinoline, the main research area is .

Human presence at intertidal areas could impact coastal biodiversity, including migratory waterbird species and the ecosystem services they provide. Assessing this impact is therefore essential to develop management measures compatible with migratory processes and associated biodiversity. Here, we assess the effects of human presence on the foraging opportunities of Hudsonian godwits (Limosa haemastica, a trans-hemispheric migratory shorebird) during their non-breeding season on Chiloé Island, southern Chile. We compared bird d. and time spent foraging in two similar bays with contrasting disturbance levels: human presence (mostly seaweed harvesters accompanied by dogs) was on average 0.9±0.4 people per 10 ha in the disturbed bay, whereas it was negligible (95% days absent) in the non-disturbed bay. Although overall abundances were similar between bays, godwit d. was higher in the non-disturbed bay throughout the low tide period. Both days after the start of the non-breeding season and tidal height significantly affected godwit d., with different effects in either bay. Time spent foraging was significantly higher in the non-disturbed bay (86.5±1.1%) than in the disturbed one (81.3±1.4%). As expected, godwit d. significantly decreased with the number of people and accompanying dogs in the disturbed bay. Our results indicate that even a low d. of people and dogs can significantly reduce the foraging opportunities of shorebirds. These constraints, coupled with addnl. flushing costs, may neg. affect godwits’ pre-migratory fattening. Hence, as a first step we suggest limiting human presence within bays on Chiloé to 1 person per 10 ha and banning the presence of accompanying dogs in sensitive conservation areas.

Dusart, A. published the artcileOccurrence of (suspected) genotoxic flavoring substances in Belgian alcohol-free beers, Computed Properties of 21834-92-4, the main research area is Belgian alc free beers flavoring substances genotoxicity; Alcohol-free beers; Flavoring substances; GC–MS; Genotoxicity; SAFE.

The regulatory landscape of flavorings is evolving, thereby putting pressure on control laboratories to develop anal. methods for a wide range of compounds in various types of food and drinks. In order to improve the monitoring of flavoring substances, a versatile and accurate anal. method using the solvent-assisted flavor evaporation (SAFE) technique coupled to GC-MS(SIM) was developed and validated. Focus was put on authorized flavoring substances requiring specific attention due to a genotoxic concern based on information from European risks assessment reports. Thirty-seven (suspected) genotoxic flavoring substances were analyzed in a selection of ten alc.-free beers. Five suspected genotoxic compounds (i.e. 1-(2-furyl)-2-propanone, 2-acetylfuran, 2-acetyl-5-methylfuran, 2-acetyl-3,5-dimethylfuran, hex-2-eno-1,4-lactone) as well as two confirmed genotoxic flavoring substances (p-mentha-1,8-dien-7-al, 2,4-pentanedione) were identified and quantified among the selected samples. Low concentrations and natural occurrences of the identified compounds suggested that these were not added as such but rather originated from heat-treatments or from plant-based extracts
