Analysis of volatile components in Asarum heterotropoides by HS-SPME/GC-MS was written by Wang, Feng;Li, Nan;Li, Xue;Zhong, Lingyan;Huang, Zetian;Hu, Ping. And the article was included in Riyong Huaxue Gongye in 2021.Quality Control of 6-Allyl-4-methoxybenzo[d][1,3]dioxole This article mentions the following:

Asarum is a kind of commonly used traditional Chinese medicine, and volatile oil is the main material basis for its efficacy. In traditional studies, the volatile oil is extracted by steam distillation and analyzed by GC-MS. Although the extraction method is easy to operate and has low cost, it is time-consuming, large sample consumption, high extraction temperature and easy thermal decomposition of active components. Moreover, xylene is often added in this method to promote the stratification of volatile oil, which brings great interference to the subsequent GC-MS anal. and component identification of volatile oil. Therefore, Solid Phase microextraction (SPME) technol. that integrates extraction, purification, enrichment, and sampling functions was used to analyze the volatile oil of Asarum for the first time. The HS-SPME/GC-MS method was established to analyze Asarum heterotropoides, and the volatile components were identified by the NIST spectral library search and retention index. A total of 68 components were identified from the volatile oil of Asarum heterotropoides from 6 origins. The relative content of Me eugenol was the highest among the volatile components with peak area percentages ranging from 17.20% to 33.80%. The application of HS-SPME/GC-MS method to the study of the volatile components in Asarum heterotropoides can reflect the overall differences, and the method is simple and rapid, providing new ideas for the quality evaluation of Asarum heterotropoides. In the experiment, the researchers used many compounds, for example, 6-Allyl-4-methoxybenzo[d][1,3]dioxole (cas: 607-91-0Quality Control of 6-Allyl-4-methoxybenzo[d][1,3]dioxole).

Functional acrylic resin based on the terpolymer of Bu acrylate (BA)-Me methacrylate (MMA)-glycidyl methacrylate (GMA) was prepared The terpolymer was treated with CO2 gas flow in the presence of cetyltrimethyl ammonium bromide as a catalyst. In terms of the carbonation reaction time, poly(MMA-co-BA-co-GMA-co-2-oxo-1,3-dioxolane-4-yl-Me methacrylate) was prepared in various yields of CO₂ fixation (>90%).

Chemical reactivity and safener activity of acetal compounds was written by Ekler, Zsigmond;Dutka, Ferenc. And the article was included in Zeitschrift fuer Naturforschung, C: Journal of Biosciences in 1991.SDS of cas: 2568-30-1 This article mentions the following:

The chem. reactivity of acetamide-type compounds as well as their safener activity against thiocarbamate herbicides change with the number of chlorine substituents in the order: nonchlorinated < monochloro < dichloro. Several compounds of another chem. group, acetal (e.g., MG-191, 2-dichloromethyl-2-methyl-1,3-dioxolane), are also effective safeners for thiocarbamate herbicides. According to growthroom studies, the safener activity of acetals also increases with increasing chlorine content up to two chlorine atoms on the same carbon. A number of differently chlorinated acetals were synthesized and their acid-catalyzed hydrolysis rate determined in order to establish a relationship between their bioactivity and chem. reactivity. The hydrolysis rate order of acetals (nonchlorinated > monochloro > dichloro) is the opposite of that found for acetamides. Thus, safener activity of acetals increases with decreasing chem. reactivity. The opposite reactivity order of acetamides and acetals can be explained by the different mechanisms of their hydrolysis. Dichloroacetals are not effective safeners without further modification. In plants, however, they may be activated by a nonhydrolytic pathway. In the experiment, the researchers used many compounds, for example, 2-Chloromethyl-1,3-dioxolane (cas: 2568-30-1SDS of cas: 2568-30-1).

eCF309: a potent, selective and cell-permeable mTOR inhibitor was written by Fraser, Craig;Carragher, Neil O.;Unciti-Broceta, Asier. And the article was included in MedChemComm in 2016.COA of Formula: C4H7BrO2 This article mentions the following:

Kinase inhibitors capable of blocking the phosphorylation of protein substrates with high selectivity are essential to probe and elucidate the etiol. role of such mols. and their signalling pathways. By addressing these biochem. questions in disease relevant cell-based and in vivo models, strong pharmacol. evidence can be generated towards validating or disproving a target hypothesis. Pharmacol. studies can also provide fundamental information to identify appropriate biomarkers and rational drug combination strategies and thereby facilitate clin. translation. However, due to the high number of kinases encoded by the human genome (>500) and their highly conserved catalytic domains, the development of such an elite class of inhibitors-a.k.a. high-quality chem. probes-represents a major challenge. Through a ligand-based inhibitor design, focused library synthesis and phenotypic screening to prioritize compounds with potent cell activity, we recently identified a cell cycle inhibitor with micromolar potency that inhibits mTOR kinase activity. Following a rapid lead optimization campaign, we report the development of eCF309, an mTOR inhibitor displaying low nanomolar potency both in vitro and in cells and an excellent selectivity profile (S-score (35%) = 0.01 at 10 μM). In the experiment, the researchers used many compounds, for example, 2-Bromomethyl-1,3-dioxolane (cas: 4360-63-8COA of Formula: C4H7BrO2).

Gas-phase sugar formation using hydroxymethylene as the reactive formaldehyde isomer was written by Eckhardt, Andre K.;Linden, Michael M.;Wende, Raffael C.;Bernhardt, Bastian;Schreiner, Peter R.. And the article was included in Nature Chemistry in 2018.Category: dioxole This article mentions the following:

Carbohydrates (CH₂O)_n are the formal adducts of carbon (atoms) to water with a repeating unit that structurally resembles H-C-OH (hydroxymethylene). Although hydroxymethylene has been suggested as a building block for sugar formation, it is a reactive species that had escaped detection until recently. Here we demonstrate that formaldehyde reacts with its isomer hydroxymethylene to give glycolaldehyde in a nearly barrierless reaction. This carbonyl-ene-type transformation operates in the absence of base and solvent at cryogenic temperatures similar to those found in extraterrestrial environments or interstellar clouds. Hydroxymethylene acts as a building block for an iterative sugar synthesis, as we demonstrate through the formation of the triose glyceraldehyde. The thermodynamically preferred ketose dihydroxyacetone does not form, and the formation of further branched sugars in the iterative synthesis presented here is unlikely. The results therefore provide a link between the well-known formose (Butlerow) reaction and sugar formation under non-aqueous conditions. In the experiment, the researchers used many compounds, for example, (R)-2,2-Dimethyl-1,3-dioxolane-4-carbaldehyde (cas: 15186-48-8Category: dioxole).
