On September 7, 2020, Kraszewski, Karol; Tomczyk, Ireneusz; Drabinska, Aneta; Bienkowski, Krzysztof; Solarska, Renata; Kalek, Marcin published an article.Name: 2,4-Di-tert-butylphenol The title of the article was Mechanism of Iodine(III)-Promoted Oxidative Dearomatizing Hydroxylation of Phenols: Evidence for a Radical-Chain Pathway. And the article contained the following:

The oxidative dearomatization of phenols with the addition of nucleophiles to the aromatic ring induced by hypervalent iodine(III) reagents and catalysts has emerged as a highly useful synthetic approach. However, exptl. mechanistic studies of this important process have been extremely scarce. In this report, we describe systematic investigations of the dearomatizing hydroxylation of phenols using an array of exptl. techniques. Kinetics, EPR spectroscopy, and reactions with radical probes demonstrate that the transformation proceeds by a radical-chain mechanism, with a phenoxyl radical being the key chain-carrying intermediate. Moreover, UV and NMR spectroscopy, high-resolution mass spectrometry, and cyclic voltammetry show that before reacting with the phenoxyl radical, the water mol. becomes activated by the interaction with the iodine(III) center, causing the Umpolung of this formally nucleophilic substrate. The radical-chain mechanism allows the rationalization of all existing observations regarding the iodine(III)-promoted oxidative dearomatization of phenols. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Name: 2,4-Di-tert-butylphenol

Saraiva, Ariana; Carrascosa, Conrado; Raheem, Dele; Ramos, Fernando; Raposo, Ant Onio published an article in 2020, the title of the article was Maltitol: analytical determination methods, applications in the food industry, metabolism and health impacts.Computed Properties of 585-88-6 And the article contains the following content:

A review. Bulk sweetener maltitol belongs to the polyols family and there have been several dietary applications in the past few years, during which the food industry has used it in many food products: bakery and dairy products, chocolate, sweets. This review paper addresses and discusses in detail the most relevant aspects concerning the anal. methods employed to determine maltitol’s food safety and industry applications, its metabolism and its impacts on human health. According to our main research outcome, we can assume that maltitol at lower doses poses little risk to humans and is a good alternative to using sucrose. However, it causes diarrhoea and foetus complications at high doses. Regarding its determination, high-performance liquid chromatog. proved the primary method in various food matrixes. The future role of maltitol in the food industry is likely to become more relevant as processors seek alternative sweeteners in product formulation without compromising health.

The design of new dual-function inhibitors simultaneously preventing hydrate formation and corrosion is a relevant issue for the oil and gas industry. The structure-property relationship for a promising class of hybrid inhibitors based on waterborne polyurethanes (WPU) was studied in this work. Variation of diethanolamines differing in the size and branching of N-substituents (Me, Bu, and tert-butyl), as well as the amount of these groups, allowed the structure of polymer mols. to be preset during their synthesis. To assess the hydrate and corrosion inhibition efficiency of developed reagents pressurized rocking cells, electrochem. and weight-loss techniques were used. A distinct effect of these variables altering the hydrophobicity of obtained compounds on their target properties was revealed. Polymers with increased content of diethanolamine fragments with n- or tert-Bu as N-substituent (WPU-6 and WPU-7, resp.) worked as dual-function inhibitors, showing nearly the same efficiency as com. ones at low concentration (0.25 wt%), with the branched one (tert-butyl; WPU-7) turning out to be more effective as a corrosion inhibitor. Com. kinetic hydrate inhibitor Luvicap 55 W and corrosion inhibitor Armohib CI-28 were taken as reference samples. Preliminary study reveals that WPU-6 and WPU-7 polyurethanes as well as Luvicap 55 W are all poorly biodegradable compounds; BODt/CODcr (ratio of BOD and COD) value is 0.234 and 0.294 for WPU-6 and WPU-7, resp., compared to 0.251 for com. kinetic hydrate inhibitor Luvicap 55 W. Since the obtained polyurethanes have a bifunctional effect and operate at low enough concentrations, their employment is expected to reduce both operating costs and environmental impact. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Safety of 2,2′-(tert-Butylazanediyl)diethanol

On January 31, 2022, Vahdati, Saeed Niazi; Lashkari, Ali; Navasatli, Sepideh Aliniaye; Ardestani, Susan Kabudanian; Safavi, Maliheh published an article.Electric Literature of 96-76-4 The title of the article was Butylated hydroxyl-toluene, 2,4-Di-tert-butylphenol, and phytol of Chlorella sp. protect the PC12 cell line against H2O2-induced neurotoxicity. And the article contained the following:

Oxidative stress is considered the main cause of cellular damage in a number of neurodegenerative disorders. One suitable ways to prevent cell damage is the use of the exogenous antioxidant capacity of natural products, such as microalgae. In the present study, four microalgae extracts, isolated from the Persian Gulf, were screened to analyze their potential antioxidant activity and free radical scavenging using ABTS, DPPH, and FRAP methods. The methanolic extracts (D1M) of green microalgae derived from Chlorella sp. exhibited potent free radical scavenging activity. In order to characterize microalgae species, microscopic observations and anal. of the expression of 18S rRNA were performed. The antioxidant and neuroprotective effects of D1M on H2O2-induced toxicity in PC12 cells were investigated. The results demonstrated that D1M significantly decreased the release of nitric oxide (NO), formation of intracellular reactive oxygen species (ROS), and the level of malondialdehyde (MDA), whereas it enhanced the content of glutathione (GSH), and activity of heme oxygenase 1 (HO-1), NAD(P)H: quinone oxidoreductase 1 (NQO1), and catalase (CAT) in PC12 cells exposed to H2O2. The pretreatment of D1M improved cell viability as measured by the MTT assay and invert microscopy, reduced cell apoptosis as examined by flow cytometry anal., increased mitochondrial membrane potential (MMP), and diminished caspase-3 activity. The GC/MS anal. revealed that D1M ingredients have powerful antioxidant and anti-inflammatory compounds, such as butylated hydroxytoluene (BHT), 2,4-di-tert-butyl-phenol (2,4-DTBP), and phytol. These results suggested that Chlorella sp. extracts have strong potential to be applied as neuroprotective agents, for the treatment of neurodegenerative disorders.

On January 15, 2022, Sun, Nan; Gao, Zhiyi; Li, Shiqi; Chen, Xiaowen; Guo, Jing published an article.Reference of 2,4-Di-tert-butylphenol The title of the article was Assessment of chemical constitution and aroma properties of kiwi wines obtained from pure and mixed fermentation with Wickerhamomyces anomalus and Saccharomyces cerevisiae. And the article contained the following:

To improve the aroma of kiwi wine through the utilization of Wickerhamomyces anomalus, kiwi juice was fermented using a selected W. anomalus strain in pure culture and mixed fermentations with Saccharomyces cerevisiae, which was inoculated simultaneously and sequentially. The physicochem. indexes, volatile compounds and aroma properties of the kiwi wines were assessed. The study suggested that the ethanol, color indexes and organic acids of the wines were closely related to the method of inoculation. Compared with the pure S. cerevisiae fermentation, the mixed fermentations produced more varieties and concentrations of volatiles. The sequential fermentations increased the concentrations of esters and terpenes, improving the flower and sweet fruit notes of the wines. The simultaneous inoculation enhanced the contents of esters and aldehydes, intensifying the flower, sweet and sour fruit of the wines. Partial least-squares regression anal. showed that esters and terpenes contributed greatly to the flower and sweet fruit aroma, whereas aldehydes were the major contributors to the sour note. Based on our results, the mixed fermentations not only enriched the types and concentrations of volatiles, but also had better sensory properties. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Reference of 2,4-Di-tert-butylphenol

On August 17, 2021, Lowe, Charles N.; Phillips, Katherine A.; Favela, Kristin A.; Yau, Alice Y.; Wambaugh, John F.; Sobus, Jon R.; Williams, Antony J.; Pfirrman, Ashley J.; Isaacs, Kristin K. published an article.Related Products of 96-76-4 The title of the article was Chemical Characterization of Recycled Consumer Products Using Suspect Screening Analysis. And the article contained the following:

Recycled materials are found in many consumer products as part of a circular economy; however, the chem. content of recycled products is generally uncharacterized. A suspect screening anal. using two-dimensional gas chromatog. time-of-flight mass spectrometry (GC x GC-TOFMS) was applied to 210 products (154 recycled, 56 virgin) across seven categories. Chems. in products were tentatively identified using a standard spectral library or confirmed using chem. standards A total of 918 probable chem. structures identified (112 of which were confirmed) in recycled materials vs. 587 (110 confirmed) in virgin materials. Identified chems. were characterized in terms of their functional use and structural class. Recycled paper products and construction materials contained greater numbers of chems. than virgin products; 733 identified chems. had greater occurrence in recycled compared to virgin materials. Products made from recycled materials contained greater numbers of fragrances, flame retardants, solvents, biocides, and dyes. The results were clustered to identify groups of chems. potentially associated with unique chem. sources, and identified chems. were prioritized for further study using high-throughput hazard and exposure information. While occurrence is not necessarily indicative of risk, these results can be used to inform the expansion of existing models or identify exposure pathways currently neglected in exposure assessments. The experimental process involved the reaction of 2,4-Di-tert-butylphenol(cas: 96-76-4).Related Products of 96-76-4

On June 30, 2020, Chen, Haitao; Xu, Chao; Zhang, Fan; Liu, Yu; Guo, Yong; Yao, Qinghua published an article.Computed Properties of 621-37-4 The title of the article was The gut microbiota attenuates muscle wasting by regulating energy metabolism in chemotherapy-induced malnutrition rats. And the article contained the following:

Malnutrition is a common clin. symptom in cancer patients after chemotherapy, which is characterized by muscle wasting and metabolic dysregulation. The regulation of muscle metabolism by gut microbiota has been studied recently. However, there is no direct convincing evidence proving that manipulating gut microbiota homeostasis could regulate muscle metabolic disorder caused by chemotherapy. Here, we investigate the potential role of gut microbiota in the regulation of the muscle metabolism in 5-fluorouracil (5-Fu)-induced malnutrition rat model. Male Sprague-Dawley rats were randomly divided into two groups (n = 8/group): control group and 5-Fu group. In the 5-Fu group, rats received 5-Fu (40 mg/kg/day) by i.p. injection for 4 days, and all rats were raised for 8 days. Nutritional status, muscle function, muscle metabolites, and gut microbiota were assessed. Fecal microbiota transplantation (FMT) was applied to explore the potential regulation of gut microbiota on muscle metabolism 5-Fu-treated rats exhibited loss of body weight and food intake compared to control group. 5-Fu decreased the levels of total protein and albumin in serum, and significantly increased the levels of IL-6 and TNF-α in muscle tissue. Rats that received 5-Fu displayed concurrent reduction of muscle function and fiber size. Moreover, 5-Fu group showed a distinct profile of gut microbiota compared to control group, including the relative lower abundance of Firmicutes and a higher abundance of Proteobacteria and Verrucomicrobia. Fourteen differential muscle metabolites were identified between two groups, which were mainly related to glycolysis, amino acid metabolism, and TCA cycle pathway. Furthermore, fecal transplantation from healthy rats improved nutritional status and muscle function in 5-Fu-treated rats. Notably, FMT inhibited the inflammatory response in muscle, and reversed the changes of several differential muscle metabolites and energy metabolism in 5-Fu-treated rats. Study demonstrated that gut microbiota played an important role in the regulation of muscle metabolism and promoting muscle energy production in 5-Fu-induced malnutrition rats, suggesting the potential attenuation of chemotherapy-induced muscle wasting by manipulating gut microbiota homeostasis. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Computed Properties of 621-37-4
