Hinneh, Michael published the artcilePod storage with roasting: A tool to diversifying the flavor profiles of dark chocolates produced from ‘bulk’ cocoa beans? (part I: aroma profiling of chocolates), Synthetic Route of 21834-92-4, the main research area is aroma flavor dark chocolate cocoa bean; Aroma profile; Chocolate; Cocoa; HS-SPME-GC–MS; Pod storage; Roasting.

The impact of pod storage (PS) and roasting temperature (RT) on the aroma profiles of dark chocolates were evaluated. Cocoa liquor samples comprised of ten different combinations of PS and RT, while keeping the roasting time fixed at 35 min. Addnl., com. cocoa liquors from renowned origins (Ecuador, Madagascar, Venezuela, Vietnam, Ivory Coast and Ghana) were acquired for comparison. From these, 70% dark chocolates were produced under the same conditions after which they were subjected to headspace solid-phase microextraction-gas chromatog.-mass spectrometry (HS-SPME-GC-MS) anal. Although both PS and RT were found to influence the aroma volatile concentrations, the impact of RT over PS seemed to be greater. An agglomerative hierarchical clustering (AHC) of all chocolates on the basis of their aroma profiles revealed a similar impact as earlier observed, where major clustering of the chocolates was in accordance with the intensity of the roasting process applied. However, within each group, the dissimilarities owing to PS among the chocolates was clearly depicted. Comparatively, chocolates with low (100-120 °C), instead of moderate to high (135-160 °C) RT’s, rather showed a low dissimilarity with those from the com. cocoa liquors of the different origins. Although from the same beans, the diversity of aroma profiles of these chocolates as well as the similitude of some treatments to some chocolates from com. grade cocoa liquors, unequivocally underscores the possibility for steering diverse distinct flavors from ‘bulk’ cocoa through PS and roasting, with beneficial implications, both from an application and an economic point of view.

Shah, Umang published the artcileIdentification of chalcone derivatives as putative non-steroidal aromatase inhibitors potentially useful against breast cancer by molecular docking and ADME prediction, Recommanded Product: 2,3-Dimethoxybenzaldehyde, the main research area is breast cancer chalcone anticancer nonsteroidal aromatase inhibitor mol docking.

Aromatase is an influential target to overcome estrogen receptor pos. breast cancer, as the enzyme is responsible for conversion of androstenedione to estrone, a promising drug target for therapeutic management of breast cancer. Chalcones are prominent biosynthetic compounds and parent candidate for the synthesis of heterocycles with diversified biol. activities. The prime objective of the present study is to evaluate the binding interaction of 2-hydroxyphenyl- prop-2-en-1-one (1A-1X), 2-hydroxy-4-methoxyphenyl- prop-2-en-1-one (3A-3X), 2,4-dihydroxyphenyl- prop-2-en-1-one (9A-9X) and 1-hydroxynaphthalen-2-yl-prop-2-en-1-one (5A-5X) derivatives with aromatase enzyme by mol. docking study and also check their ADME properties by maestro suit. The designed chalcones derivatives have been docked against our target protein with PDB id 3S7S retrieved from the protein data bank, whereas exemestane has been taken as the pos. control. As docking data revealed that docking score of 1K, 1U, 1B 3K 3N, 5K, 5U, 9S, 9K, 9N and 9F compounds found less than exemestane and all of these compounds with appropriate ADME properties have proven their excellent absorption as well as solubility characteristics. The present findings provided valuable information about binding interactions of chalcones derivatives to the active site of aromatase. These compounds may serve as potential lead compound for developing new aromatase inhibitors in breast cancer treatment.

Wei, Ya-Nan published the artcileStructural changes for lignin from Chinese quince during the sequential fractionation of cell wall polysaccharides, Formula: C9H10O3, the main research area is Chinese quince cell wall polysaccharide sequential fractionation lignin structure; mol weight distribution.

The crosslinking between lignin and cell wall polysaccharides is one of recalcitrance to extract pectin and hemicellulose. In this work, water-, chelator-, Na2CO3-soluble pectin (WSP, CSP, NSP) and alkali-soluble hemicellulose (ASH) were sequentially removed, milled wood lignins (WMWL, CMWL, NMWL and KMWL) were isolated from Chinese quince. Quant. chem. anal. techniques (e.g., HPAEC, FT-IR, GPC, Py-GC/MS, TG and 2D NMR) were used for characterizing the lignin fractions. Results indicate that there are tight linkages between arabinose and lignin. The mol. weight and thermal stability decreased as different types of pectin (WSP, CSP and NSP) were removed. Py-GC/MS and 2D NMR data showed that the major interunit β-O-4′ aryl ether bonds of lignin (61.07%-72.53%) and the S/G ratios (0.56-2.68) were changed. It was revealed that Chinese quince pectin and hemicellulose polysaccharides have more covalent crosslinks with S-type lignin from secondary wall S2 than G-type lignin. These results will contribute to realizing the mechanisms of cell wall polysaccharides isolation and be beneficial for the potential application of Chinese quince fruits in food and other industries.

Based on the interaction modes of the natural 20S proteasome inhibitors , we have previously discovered a dipeptide . To explore the SAR around compound , we designed and synthesized a series of dipeptides () with a fragment-based strategy. Among them, nine compounds showed significant inhibitory activities against the chymotrypsin-like activity of human 20S proteasome with IC50 values at the submicromolar level, which were comparable or even superior to the parent compound Meanwhile, they displayed no significant inhibition against trypsin-like and caspase-like activities of 20S proteasome. The results suggested the feasibility to design dipeptides as novel and potent 20S proteasome inhibitors.
