The aim of this study is the chem. and sensory description of the aroma of wines white Chelva through five successive vintages. Solid Phase Extraction (SPE) was used for the isolation of volatile compounds and Gas Chromatog. Mass Spectrometry (GC-MS) was employed by their anal. Aroma Sensory Profile of wines was defined using the Quant. Descriptive Sensory Anal. (QDA). A total of 77 volatile compounds were identified in Chelva wines. Chelva wines present a great quantity of aromatic compounds of very different chem. nature and with different aromatic descriptors, which will increase its aromatic complexity of these wines. Aroma sensory profile of Chelva wines was defined by higher intensity of fresh and peach aromas with notes citric, green apple, tropical fruit and sweet. This study showed that the Chelva grapes variety cultivated in La Mancha region present a great aroma potential and a complex sensory profile and can be considered a viable alternative to traditional grape varieties cultivated in this region for increasing the offer to the consumer.

Gu, Zixuan; Jiang, Haiyang; Zha, Fengchao; Manthey, Frank; Rao, Jiajia; Chen, Bingcan published the artcile< Toward a comprehensive understanding of ultracentrifugal milling on the physicochemical properties and aromatic profile of yellow pea flour>, Recommanded Product: 2-Ethylhexan-1-ol, the main research area is Pisum Starch damage Aromatic profile Untargeted metabolomics; Aromatic profile; Plant-based ingredients; Starch damage; Untargeted metabolomic approaches; Yellow pea.

Yellow pea (Pisum sativum L., YP) grain is generally milled into flour for further processing or direct consumption. However, the comprehensive relationship between milling configurations and YP flour properties remains unclear. The aim of this study is to investigate the effect of configurations (screen aperture size and rotor speed) of ultracentrifugal mill on the physicochem. properties and aromatic profiles of YP flours. Starch damage, morphol., particle size distribution, pasting, thermal property, and aromatic profiles of YP flours were studied. Results show that starch damage increased significantly as the screen aperture size decreased. The YP flour produced with a 500 μm aperture screen had the most stable pasting and thermal properties. With untargeted metabolomic approaches, 2-ethyl-1-hexanol could potentially be applied as an aroma maker to distinguish if an excessive milling or inappropriate configurations of ultracentrifugal mill are applied. This work has furnished fundamentals for the milling and application of YP flour.

Soszka, N.; Hachula, B.; Tarnacka, M.; Kaminska, E.; Pawlus, S.; Kaminski, K.; Paluch, M. published the artcile< Is a Dissociation Process Underlying the Molecular Origin of the Debye Process in Monohydroxy Alcohols?>, SDS of cas: 104-76-7, the main research area is glass former monohydroxy alc Debye relaxation hydrogen bond dissociation; activation barrier broad band dielec spectroscopy FTIR.

Herein, we investigated the mol. dynamics as well as intramol. interactions in two primary monohydroxy alcs. (MA), 2-ethyl-1-hexanol (2EHOH) and n-butanol (nBOH), by means of broad-band dielec. (BDS) and Fourier transform IR (FTIR) spectroscopy. The modeling data obtained from dielec. studies within the Rubinstein approach [Macromols. 2013, 46, 7525-7541] originally developed to describe the dynamical properties of self-assembling macromols. allowed us to calculate the energy barrier (Ea) of dissociation from the temperature dependences of relaxation times of Debye and structural processes. We found Ea ~19.4 ± 0.8 and 5.3 ± 0.4 kJ/mol for the former and latter systems, resp. On the other hand, FTIR data analyzed within the van’t Hoff relationship yielded the energy barriers for dissociation Ea ~20.3 ± 2.1 and 12.4 ± 1.6 kJ/mol for 2EHOH and nBOH, resp. Hence, there was almost a perfect agreement between the values of Ea estimated from dielec. and FTIR studies for the 2EHOH, while some notable discrepancy was noted for the second alc. A quite significant difference in the activation barrier of dissociation indicates that there are probably supramol. clusters of varying geometry or a ring-chain-like equilibrium is strongly affected in both alcs. Nevertheless, our anal. showed that the association/dissociation processes undergoing within nanoassocs. are one of the main factors underlying the mol. origin of the Debye process, supporting the transient chain model.

A convenient protocol for the 1-pot synthesis of quinazolin-4(3H)-ones using Pd(II) complexes via dehydrogenative coupling of readily available benzyl alcs. and 2-aminobenzamide was described. New structurally related Pd(II) N^O chelating complexes of general configuration [Pd(L)Cl(PPh3)] (L = dimethylamino benzoylhydrazone ligands) were designed and synthesized. The formation of the complexes was recognized by anal. and spectral methods (FTIR, NMR, HR-MS). The presence of a square-planar geometry around the Pd(II) ion was confirmed by single crystal x-ray diffraction study. A wide range of substituted quinazolinones were successfully achieved from a diverse range of benzyl alcs. in good to excellent yields using 1.0 mol % of catalyst loading under aerobic conditions. Also, control experiments reveal that the dehydrogenative coupling reaction involves initially the formation of an aldehyde intermediate and subsequent formation of a cyclic aminal intermediate.

Compared PF-543 I and synthesized a newly designed derivative of PF-543 II in which two aromatic structures were connected in para-form. The synthesized derivative II showed inhibitory effect on SK1, similar to that of PF-543 I. However, it was more cytotoxic to HT29, AGS, and PC3 cells than PF-543 I. Also carried out a docking study for SK1 and demonstrated that the synthesized derivative II showed interaction with SK1 similar to PF-543 I. Results obtained from this study suggest that the structure of II may be well substituted for the structure of PF-543 I in terms of biol. activity, providing important structural information for the design of new derivatives of PF-543 II.

Syed-Ab-Rahman, Sharifah Farhana; Carvalhais, Lilia C.; Chua, Elvis T.; Chung, Fong Yi; Moyle, Peter M.; Eltanahy, Eladl G.; Schenk, Peer M. published the artcile< Soil bacterial diffusible and volatile organic compounds inhibit Phytophthora capsici and promote plant growth>, Category: alcohols-buliding-blocks, the main research area is soil bacteria volatile antioomycete biocontrol Phytophthora plant growth; Anti-oomycete; Biocontrol; Phytophthora capsici; SPME-GC–MS; Soil bacteria; Volatile.

Biotic interactions through diffusible and volatile organic compounds (VOCs) are frequent in nature. Soil bacteria are well-known producers of a wide range of volatile compounds (both organic and inorganic) with various biol. relevant activities. Since the last decade, they have been identified as natural biocontrol agents. Volatiles are airborne chems., which when released by bacteria, can trigger plant responses such as defense and growth promotion. In this study, we tested whether diffusible and volatile organic compounds (VOCs) produced by soil bacterial isolates exert anti-oomycete and plant growth-promoting effects. We also investigated the effects of inoculation with VOC-producing bacteria on the growth and development of Capsicum annuum and Arabidopsis thaliana seedlings. Our results demonstrate that organic VOCs emitted by bacterial antagonists neg. influence mycelial growth of the soil-borne phytopathogenic oomycete Phytophthora capsici by 35% in vitro. The bacteria showed plant growth promoting effects by stimulating biomass production, primary root growth and root hair development. Addnl., we provide evidence to suggest that these activities were deployed by the emission of either diffusible organic compounds or VOCs. Bacterial VOC profiles were obtained through solid phase microextraction (SPME) and anal. by gas chromatog. coupled with mass spectrometry (GC-MS). This elucidated the main volatiles emitted by the isolates, which covered a wide range of aldehydes, alcs., esters, carboxylic acids, and ketones. Collectively, twenty-five VOCs were identified to be produced by three bacteria; some being species-specific. Our data show that bacterial volatiles inhibits P. capsici in vitro and modulate both plant growth promotion and root system development. These results confirm the significance of soil bacteria and highlights that ways of harnessing them to improve plant growth, and as a biocontrol agent for soil-borne oomycetes through their volatile emissions deserve further investigation.

We study the properties and phase behavior of the H2O-diesel fuel-Neonol AF 9-6/2-ethylhexanol system, which is regarded as a promising microemulsion fuel. A pseudoternary diagram of the system has been obtained. In the diesel fuel/H2O (DF/W) ratio ranging from 98:2-50:50 and the emulsifier concentration of 8-40 volume%, a region of microemulsions has been distinguished, generating particular interest as an alternative fuel. In the region under study, a reverse micellar phase L2 has existed predominantly. Fish-cut diagrams have been obtained for the DF/W ratios in the emulsifier concentration-temperature coordinates. An increase in the H2O fraction in microemulsions significantly has narrowed the range of their stability. The critical changes of microemulsion properties have been identified using the fish-cut diagrams. We established the empirical relation among the phase inversion temperature, the emulsifier concentration in the phase inversion point, and the H2O fraction in microemulsions.

Kirsch, Philine; Jakob, Valentin; Oberhausen, Kevin; Stein, Saskia C.; Cucarro, Ivano; Schulz, Thomas F.; Empting, Martin published the artcile< Fragment-Based Discovery of a Qualified Hit Targeting the Latency-Associated Nuclear Antigen of the Oncogenic Kaposi's Sarcoma-Associated Herpesvirus/Human Herpesvirus 8>, Formula: C9H8O, the main research area is Kaposi sarcoma human herpesvirus 8 antiviral LANA.

The latency-associated nuclear antigen (LANA) is required for latent replication and persistence of Kaposi’s sarcoma-associated herpesvirus/human herpesvirus 8. It acts via replicating and tethering the virus episome to the host chromatin and exerts other functions. We conceived a new approach for the discovery of antiviral drugs to inhibit the interaction between LANA and the viral genome. We applied a biophys. screening cascade and identified the first LANA binders from small, structurally diverse compound libraries. Starting from a fragment-sized scaffold, we generated optimized hits via fragment growing using a dedicated fluorescence-polarization-based assay as the structure-activity-relationship driver. We improved compound potency to the double-digit micromolar range. Importantly, we qualified the resulting hit through orthogonal methods employing EMSA, STD-NMR, and MST methodologies. This optimized hit provides an ideal starting point for subsequent hit-to-lead campaigns providing evident target-binding, suitable ligand efficiencies, and favorable physicochem. properties.
