Lee, Hiu-Fung published the artcileSynthesis and Evaluation of Structurally Diverse C-2-Substituted Thienopyrimidine-Based Inhibitors of the Human Geranylgeranyl Pyrophosphate Synthase, Category: alcohols-buliding-blocks, the publication is Journal of Medicinal Chemistry (2022), 65(3), 2471-2496, database is CAplus and MEDLINE.

Novel analogs of C-2-substituted thienopyrimidine-based bisphosphonates (C2-ThP-BPs) are described that are potent inhibitors of the human geranylgeranyl pyrophosphate synthase (hGGPPS). Members of this class of compounds induce target-selective apoptosis of multiple myeloma (MM) cells and exhibit antimyeloma activity in vivo. A key structural element of these inhibitors is a linker moiety that connects their (((2-phenylthieno[2,3-d]pyrimidin-4-yl)amino)methylene)bisphosphonic acid core to various side chains. The structural diversity of this linker moiety, as well as the side chains attached to it, was investigated and found to significantly impact the toxicity of these compounds in MM cells. The most potent inhibitor CML-07-119(13c)(I) was evaluated in mouse and rat for liver toxicity and systemic exposure, resp., providing further optimism for the potential value of such compounds as human therapeutics.

Dishman, Sarah N. published the artcileDivergent stereochemical outcomes in the insertion of donor/donor carbenes into the C-H bonds of stereogenic centers, Computed Properties of 86-48-6, the publication is Chemical Science (2022), 13(4), 1030-1036, database is CAplus and MEDLINE.

Herein, the insertion of donor/donor carbenes into stereogenic carbon centers allowing access to trisubstituted benzodihydrofurans in a single step was reported. This study illuminates, for the first time, the stereochem. impact on the carbene center and delineates the structural factors that enable control over both stereogenic centers. Sterically bulky, highly activated C-H insertion centers exhibit high substrate control yielding a single diastereomer and a single enantiomer of product regardless of the catalyst used. Less bulky, less activated C-H insertion centers exhibit catalyst control over the diastereomeric ratio (dr), where a single enantiomer of each diastereomer was observed with high selectivity. A combination of exptl. studies and DFT calculations was used to elucidate the origin of these results. First, hydride transfer from the stereogenic insertion site proceeds with high stereoselectivity to the carbene center, thus determining the absolute configuration of the product. Second, the short lived zwitterionic intermediate can diastereoselectively ring-close by a hitherto unreported SE2 mechanism that was either controlled by the substrate or the catalyst. These results demonstrate that donor/donor carbenes undergo uniquely stereoselective reactions that originate from a stepwise reaction mechanism, in contrast to the analogous concerted reactions of carbenes with one or more electron-withdrawing groups attached.

Caffrey, Andrew J. published the artcileCharacterization of Humulus lupulus glycosides with porous graphitic carbon and sequential high performance liquid chromatography quadrupole time-of-flight mass spectrometry and high performance liquid chromatography fractionation, Quality Control of 106-25-2, the publication is Journal of Chromatography A (2022), 463130, database is CAplus and MEDLINE.

Monoterpenes contribute to the characteristic aroma of several hop varieties and may occur as nonvolatile glycosides. Upon hydrolysis, the volatile terpenes are released from the glycoside precursors. Little is known, however, about the glycoside composition of hops. Seven pentose-hexose monoterpene alc. glycosides from dried Humulus lupulus L. cv. Citra cones were isolated using high performance liquid chromatog. separation and fractionation on a reverse phase phenyl-hexyl column. Further evaluation of each isolated fraction through HPLC qTOF MS with porous graphitic carbon (PGC) showed that the seven isolated monoterpenyl glycoside fractions could be further resolved into 20 isomers. Isolation on phenyl-hexyl followed by separation on PGC was needed to distinguish each isomer present. Addnl., the hop cones were screened for potential aroma glycosides. Using the PGC column combined with a database of over 900 potential glycosides, the identification of 21 addnl. monoterpene-polyol, norisoprenoid, volatile phenol, and aliphatic alc. glycosides is reported.

Zeng, Xiaotong published the artcileEffects of deproteinization methods on primary structure and antioxidant activity of Ganoderma lucidum polysaccharides, Category: alcohols-buliding-blocks, the main research area is Ganoderma polysaccharide antioxidant activity primary structure deproteinization method; Antioxidant activities; Deproteinization; Ganoderma lucidum polysaccharides; Primary structure.

Ganoderma lucidum polysaccharides (GLP) as one of water-soluble polysaccharides has attracted much attention because of its bioactivities, especially antioxidant activity. Deproteinization is an essential step in the purification process of polysaccharides. In this study, three classic deproteinization methods, including neutral protease method, TCA precipitation and CaCl2 salting out, were evaluated for crude GLP processing. The methods had ability to remove proteins (71.50-87.36%), and meanwhile polysaccharide loss (8.35-11.39%) was observed Structure anal. indicated that these deproteinization methods had no significant effect (p > 0.05) on mol. weight of polysaccharides, but led to varying degrees of glycoside bond losses (1.14-64.05%). Moreover, the antioxidant activities of deproteinized polysaccharides were measured in vitro by hydroxyl radical, reducing power, 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) free radical and ferric-reducing antioxidant power tests. Purified GLP by enzymolysis maintained the strongest antioxidants activities with the retention rate of over 47.40%, and its deproteinization efficiency and polysaccharide loss ratio were 74.03% and 11.39% resp. In view of relatively high purity and antioxidant activity, enzymolysis was a suitable deproteinization method for GLP production

Lin, Shifan published the artcileStudy on the Effect of Mentha x piperita L. Essential Oil on Electroencephalography upon Stimulation with Different Visual Effects, Category: alcohols-buliding-blocks, the main research area is Mentha piperita essential oil electroencephalog stimulation visual effect; colour; electroencephalograph; inhalation; peppermint essential oil.

Essential oils have long been used to fight infections and treat various diseases. Peppermint (Mentha x piperita L.) is an herbal medicine that has been widely used in daily life since ancient times, and it has a wide range of applications in food, cosmetics, and medicine. Mint oil is refreshing because of its cool and comfortable smell; therefore, it is often used in ethnopharmacol. studies. The present study investigated the effects of peppermint essential oil in electroencephalog. activity response to various visual stimuli. The electroencephalog. changes of participants during peppermint essential oil inhalation under white, red, and blue color stimulations were recorded. A rapid Fourier transform anal. was used to examine the electroencephalograph power spectra of the various microstates induced by inhaling the oils. Peppermint essential oil had various effects on the brain when subjected to different visual stimuli. Alpha waves increased in the prefrontal area in the white-sniffing group, which facilitated learning and thinking. In the blue-sniffing group, the changes were less pronounced than those in the red group, and the increased alpha wave activity in the occipital area was more controlled, indicating that the participants’ visual function increased in this state. Based on EEG investigations, this is the first study to indicate that vision influences the effects of peppermint essential oils. Hence, the results of this study support the use of essential oils in a broader context to serve as a resource for future studies on the effects of different types of essential oils.

Yang, Zhirui published the artcileNetwork pharmacology-based dissection of the underlying mechanisms of dyspnoea induced by zedoary turmeric oil, Formula: C10H18O, the main research area is network pharmacol dyspnoea zedoary turmeric oil; binding affinity; dyspnoea; haemoglobin; network pharmacology; zedoary turmeric oil.

Zedoary turmeric oil (ZTO) has been widely used in clinic. However, the unpleasant induced dyspnoea inevitably impedes its clin. application. Thus, it is urgent to elucidate the mechanism underlying the ZTO-induced dyspnoea. In this study, network pharmacol. was firstly performed to search the clue of ZTO-induced dyspnoea. The key target genes of ZTO-induced dyspnoea were analyzed using GO enrichment anal. and KEGG pathway anal. GO anal. suggested that haem binding could be a key mol. function involved in ZTO-induced dyspnoea. Hence, the Hb (Hb) was focused for its oxygen-carrying capacity with haem as its critical component binding to the oxygen. UV-visible absorption spectrum indicated that the ZTO injection (ZTOI) perturbed the Soret band of Hb, suggesting an interaction between ZTO and Hb. GC-MS anal. revealed that β-elemene, germacrone, curdione and furanodiene were main components of ZTOI. Mol. docking was used to illustrate the high affinity between representative sesquiterpenes and Hb, which was finally confirmed by surface plasmon resonance, suggesting their potential roles in dyspnoea by ZTO. Following a network pharmacol.-driven strategy, our study revealed an intervened Hb-based mechanism underlying the ZTO-induced dyspnoea, providing a reference for elucidating mechanism underlying adverse drug reactions of herbal medicines in clinic.
