And the article contained the following:

Both sulfur and fluorine play important roles in organic synthesis, the life science, and materials science. The direct incorporation of these elements into organic scaffolds with precise control of the oxidation states of sulfur moieties is of great significance. Herein, we report the highly selective electrochem. vicinal fluorosulfenylation and fluorosulfoxidn. reactions of alkenes, which were enabled by the unique ability of electrochem. to dial in the potentials on demand. Preliminary mechanistic investigations revealed that the fluorosulfenylation reaction proceeded through a radical-polar crossover mechanism involving a key episulfonium ion intermediate. Subsequent electrochem. oxidation of fluorosulfides to fluorosulfoxides were readily achieved under a higher applied potential with the adventitious H2O in the reaction mixture The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Application In Synthesis of 1-Decanethiol

And the article contained the following:

The amplified spontaneous emissions in blue quantum dots (QDs) are still constrained by their high thresholds due to the challenge in engineering alloyed core-shell interface in the QDs with a wide bandgap to suppress Auger recombination. Compared with their red and green counterparts, the larger reactivity difference between the alloyed shell precursors makes it hard to regulate the composition and structure of the shell, and the smaller potential barrier between the core and the alloyed shell in blue QDs renders charge carriers tunneling into surface defects easier. Here, we employ a Lewis soft base ligand, 1-decanethiol, to balance the mismatched reactivity between Zn and Cd precursors for crafting a thick gradient alloyed shell with gradually increased potential barrier, which can not only restrict the charge carriers tunneling but also smooth the confinement potential. As a result, the resulting blue QDs show a long Auger lifetime of 1.3 ns, and a low threshold of 6.9 μJ cm-2 excited by a femtosecond laser, which is the record value among all reported blue-emitting nanocrystals and comparable to those of state-of-the-art red and green QDs. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Reference of 1-Decanethiol

On October 31, 2021, Yang, Jing; Hao, Yuxin; Li, Nana; Wang, Chunyu; Liu, Yongping published an article.Application In Synthesis of 3-Hydroxyphenylacetic acid The title of the article was Metabolic and microbial modulation of phenolic compounds from raspberry leaf extract under in vitro digestion and fermentation. And the article contained the following:

Raspberry leaves, byproducts in raspberry production, are also a rich source of bioactive phytochems. In this study, the changes of phenolic compounds in raspberries leaf extract (RLE) under in vitro digestion and colonic fermentation were further studied by HPLC-MS anal. and 16S rRNA. The results showed that the phenolic compounds in RLE were relatively stable during in vitro gastric digestion; however, in the subsequent intestinal digestion and colonic fermentation, their content decreased sharply. A large amount of hydroxyphenylpropionic acid, hydroxyphenylacetic acid and urolithins were produced under the action of gut microbiota. Moreover, compared with corresponding control, RLE significantly reduced the ratio of Firmicutes/Bacteroidetes in all volunteers, increased the relative abundances of some beneficial bacteria, Enterococcus, Prevotella, and decreased the relative abundances of potential pathogens, Clostridium and Faecalibacterium. These findings suggest that RLE during in vitro digestion and fermentation has pos. effects on gut microbiota and potential value of maintaining intestinal health. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Application In Synthesis of 3-Hydroxyphenylacetic acid

And the article contained the following:

In this work, hybrid materials of single-walled carbon nanotubes (SWCNT) noncovalently functionalized with fluoroalkyl- (SWCNT/ZnPc-CF) and alkyl- (SWCNT/ZnPc-CH) substituted zinc(II) phthalocyanines were prepared The effect of fluorination of the substituents in phthalocyanine macrocycle on the functionalization degree of carbon nanotubes and sensor response to ammonia was investigated. It was shown that the type of substituents in the phthalocyanine macrocycle showed noticeable effect both on the degree of functionalization of carbon nanotubes and on the sensing performance of the investigated hybrids. The amount of phthalocyanine mols. adsorbed on SWCNT walls was shown to be 1.5 times higher in the SWCNT/ZnPc-CH hybrid. The SWCNT/ZnPc-CF layer exhibited 2 times less chemiresistive sensor response to ammonia than SWCNT/ZnPc-CH, while its sensor response was more stable at 70% relative humidity. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Application In Synthesis of 1-Decanethiol

And the article contained the following:

In this study, highly active TiO2 sensitized by a novel axial substituted subphthalocyanine H12SubPcB-OPHCH2COOH (SubPc-3) was successfully prepared via a solvothermal method. Based on the crystallog. strategy, a new packing motif of SubPc-3 consisting of ligand-convex concave-concave head-head π-interaction was discovered for the first time, which affected its catalytic performance significantly. Furthermore, the DFT and TD-DFT methods were used to study the electronic feature and excited-state properties in SubPc-3 utilizing an optimized structure. By examining the degradation of methyl orange (MO) and bromophenol blue (BB) under visible light, the photocatalytic activities of the nanocomposites were investigated. The photocatalytic degradation rate of MO and BB degradation with TiO2/SubPc-3 are 97.8% and 99.5%, which are approx. 5.26 and 1.41 times compared to pure TiO2, resp. Besides, the reusability studies indicated that the photocatalytic activity of TiO2/SubPc-3 (25:1) could be maintained above 90.1% after five circulating photo-degradation This work revealed the correlation between π-interaction of sensitizer and photocatalytic performance, as well as further confirmed the great potential of TiO2/SubPc-3 photocatalytic materials in environmental remediation. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Formula: C8H8O3

And the article contained the following:

Discovery of new catalysts is crucial for future growth and development of environmentally friendly energy conversion processes e. g. the production of hydrogen by water electrolysis. We developed an aerosol-based synthesis technique as a comparatively fast and facile method to prepare multi-metal catalysts. 22 different quinary metal compositions were synthesized and investigated with respect to their activity for the oxygen evolution (OER) and the glycerol oxidation (GOR) reactions. The impact of the element composition and the homogeneous distribution of the elements in the particles on catalytic performance were evaluated. The highest activity for OER was found for Co20Cu20Ni20Fe20Zn20. For GOR, Ag-containing catalysts were the most active, however, in most cases Ag was locally enriched and not homogeneously mixed with the other metals in the particles. Ag-based catalysts outperformed similar compositions containing one or more noble metals. The GOR selectivity of selected catalysts during long-term electrolysis was also investigated and it was shown that varying the catalyst composition via aerosol-based synthesis is a potential way to modulate the GOR selectivity. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Category: alcohols-buliding-blocks

Shukla, Ila; Azmi, Lubna; Rao, Ch. V.; Jawaid, Talha; Kamal, Mehnaz; Alkhamees, Osama A.; Alaseem, Ali M.; Alsanad, Saud M. published an article in 2022, the title of the article was Inclusive roles of protocetraric acid, a secondary metabolite from the common green shield lichen Flavoparmelia caperata in alcohol-induced hepatic injury.Safety of 2,3-Dihydroxypropanoic acid And the article contains the following content:

Flavoparmelia caperata belongs to the family Parmeliaceae which is a huge family of lichens and comprises of species that draw much attention about pharmacol. activities. Several medicinally important compounds have been reported in this lichen. Protocetraric acid is among the major metabolites possessed by this lichen. Hence, the present study is designed to look into the more inclusive role of protocetraric acid in case of alc.-induced hepatotoxicity in rats. Thirty rats were randomly divided into six groups: Group 1 served as the control group, Group 2 received ethanol, Group 3 received F. caperata ethanolic extract (FCE) 50 mg/kg, Group 4 received FCE 100 mg/kg, Group 5 received FCE 200 mg/kg and Group 6 received Liv.52 (Standard drug). At the end of the experiment, biochem. parameters, oxidative stress markers, inflammatory mediators, caspase-3 and 8 activities were studied. The liver tissues were further examined histopathol. for localization of areas of severe hepatotoxicity. Cell viability was determined by using the MTT assay in MCF-7 and HepG2 cells. Moreover, FCE increased cell viability. Protocetraric acid, erythritol, and myo-inositol were detected in GC-MS anal. The outcomes of this study reveal that FCE may prove to be supportive in the treatment of alc.-induced hepatotoxicity and oxidative stress. Results of different markers have revealed that among all, FCE (100 mg/kg) has demonstrated the best hepatoprotective activity. It also ameliorated the morphol. changes induced by alc. These observations speak about the significance of the components of the lichen extract The corrective action of FCE in alc.-induced liver damage may be due to its antioxidant, anti-inflammatory, and anti-apoptotic activities. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Safety of 2,3-Dihydroxypropanoic acid

Benoite, T.; Vigasini, Nora published an article in 2021, the title of the article was Antioxidant and antidiabetic activities of ethanolic extract of Hibiscus sabdariffa calyx and Stevia rebaudiana leaf.Safety of 2,4-Di-tert-butylphenol And the article contains the following content:

The prevalence of diabetes mellitus has increased tremendously in developing countries of tropical regions. The need for an effective and safe alternative is of importance as oral hypoglycemic drugs have reported to cause side effects on prolonged use. In the present study two tropical plants, Hibiscus sabdariffa calyx and Stevia rebaudiana leaves were assessed for their in vitro antioxidant and antidiabetic activities. Total phenol and flavonoids of ethanolic extracts were quantified. Bioactive compounds were screened by Gas Chromatog. Mass Spectrometry (GC-MS) anal. Antioxidant activity was assessed by 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) and superoxide radical scavenging assays. Antidiabetic ability was evaluated by inhibition of enzymes involved in carbohydrate metabolism Glucose uptake by 3T3-L1 cells was also assessed. Ethanolic extract of Stevia leaf (EtSL) had a higher percentage of phenol and flavonoids. The GC-MS anal. showed the presence of phytochems. like Phenol-2,4-bis (1,1-dimethylethyl) in Roselle calyx and 6-methoxyflavone in Stevia leaves. The antioxidant assessment showed that EtSL significantly inhibited superoxide radical (IC50 = 45.81±1.21 μg/mL). The antidiabetic assessment revealed that Ethanolic extract of Roselle calyx (EtRC) showed strong inhibition of alpha amylase (IC50 = 27.95±0.32 μg/mL) and alpha glucosidase (IC50 = 6.21±0.18 μg/mL). Glucose uptake in 3T3-L1 cells demonstrated that both plants had significant insulin sensitizing ability. It was also revealed that the phenol and flavonoid content strongly correlated with IC50 values of antioxidant and antidiabetic assays. Results of this study show that both plants are a potential source of bioactive phytochems. and can be used as a plant-based antioxidant and antidiabetic agent. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Safety of 2,4-Di-tert-butylphenol

Mohamedshah, Zulfiqar; Hayes, Micaela; Chadwick-Corbin, Sydney; Neilson, Andrew P.; Ferruzzi, Mario G. published an article in 2022, the title of the article was Bioaccessibility, gut microbial metabolism and intestinal transport of phenolics from 100% Concord grape juice and whole grapes are similar in a simulated digestion and fecal fermentation model.Recommanded Product: 3-Hydroxyphenylacetic acid And the article contains the following content:

Phenolic rich 100% grape juice has been associated with many health benefits, but its place in dietary guidance is controversial relative to whole fruit. Direct comparisons of phenolic profiles and bioavailability between these food forms are needed. Phenolic bioaccessibility and metabolism from Concord (CG) and Niagara (NG) grapes and corresponding 100% juices were investigated using an in vitro digestion coupled with anaerobic gut fermentation model. Intestinal transport of resulting bioaccessible phenolics and microbial metabolites was estimated using a Caco-2 cell model. Total bioaccessible phenolics from both upper and lower digestion were similar (P > 0.05) between NG (400.9 ± 26.3 μmol per 100 g) and NGJ (349.5 ± 8.3 μmol per 100 g) and significantly different (P < 0.05) between CG (417.2 ± 24.4 μmol per 100 g) and CGJ (294.3 ± 45.4 μmol per 100 g) total cellular transport of phenolics was similar (P > 0.05) between whole grapes (89.4 ± 5.3 μmol per 100 g for CG, and 71.8 ± 2.4 μmol per 100 g for NG) and 100% juices (88.0 ± 5.6 μmol per 100 g for CGJ, and 85.3 ± 9.4 μmol per 100 g for NGJ). Differences were observed between the location of phenolic metabolism, bioaccessibility and subsequent cellular transport of individual phenolics between grapes and juice matrixes. Specifically, greater amounts of phenolics were transported from grape juices than whole grapes from the upper tract. However, cumulative bioaccessibility and transport from upper and lower GI digestion/fermentation together indicates that the absorbable phenolics from 100% grape juice is similar to that of whole grapes, suggesting that phenolic-mediated health benefits from consumption of whole fruit and juice may be similar.
