The research results were published in《Angewandte Chemie, International Edition》 in 2022.SDS of cas: 119-47-1 The article conveys some information:

A novel approach for various asym. transformations of cyclic enones, e.g., 2-cyclohepten-1-one has been described. The combination of readily accessible chiral diamines and sterically demanding flexible phosphoric acids resulted in a simple and highly tunable catalyst framework. The careful optimization of the catalyst components led to the identification of a particularly powerful and multi-purpose organocatalyst, which was successfully applied for asym. epoxidations, aziridinations, aza-Michael-initiated cyclizations, as well as for a novel Robinson-like Michael-initiated ring closure/aldol cyclization. High catalytic activities and excellent stereocontrol were observed for all four reaction types, indicating the excellent versatility of the catalytic system. Furthermore, a simple change in the diamine’s configuration provided easy access to both product antipodes in all cases. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

The article was appeared in 《ACS Sustainable Chemistry & Engineering》. They have made some progress in their research.HPLC of Formula: 119-47-1 The article mentions the following:

This work studied the effect of cellulose-lignin interactions under potassium formate (HCOOK) and nickel formate (Ni(HCOO)₂) on behavior and product distributions. The results indicated that the presence of HCOOK affected the whole thermal decomposition process, while the effect of Ni(HCOO)₂ was mainly manifested before 339°C. The interaction under the action of HCOOK favored the generation of carbonyl compounds, and the catalytic pyrolysis with Ni(HCOO)₂ was better for formating phenols. The high peak intensities of CO and CH₄ were achieved by adding nickel formate and potassium formate, resp. It was obviously different from noncatalytic pyrolysis. The evolution of a char structure further revealed that different formate salts had different effects on the interactions. The statistical method according to the distribution of the liquid component confirmed that HCOOK had the strongest effect for reducing the cellulose-lignin interactions. To complete the study, the researchers used 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

The article contains the following contents:

This study evaluates six formulations in improving the oxidation stability of different fatty acid Me esters (MEs). Two MEs differed in the unsaturation levels as they were synthesized from different feedstock: a blend of soybean and sunflower oils, and waste cooking oil; they did not fulfill the requirements of the EN 14214 standard concerning their oxidation stability (≈0.6 h) and some impurities. The third MEs (SoSuME-EN) were fully compliant with the standard Five formulations were phenolic-based, containing single or mixed antioxidant compounds of different mol. structures; one was amine-based. Different dosages of the formulations were added to the ME samples (corresponding to the addition range 50-48300 ppm). The MEs stability expressed as induction periods, IP, determined by the Rancimat method, were used for the calculation of stabilization factors, SF, indicating the efficiency of the applied formulation. The formulation containing 2-(1,1-dimethyl-ethyl)-1,4-benzenediol was the most efficient concerning the lowest consumption rate and the highest SF achieved for the low quality ME. 2,2′-Methylene-bis-(4-methyl-6-tert-butylphenol) was linked with higher antioxidant potency than the amine-based formulation and the phenolic compounds with two bulky tert-Bu groups. Among the 4 selected phenolic additives, butylated hydroxytoluene and 2,2′-methylene-bis-(4-methyl-6-tert-butylphenol) had similar efficiency in SoSuME-EN (at ≈500 ppm they produced SF ≈ 2), while it took twice of this amount for mixed butylphenols to achieve the same effect. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

High ionic conductivity, strong stability to lithium metal, convenient preparation and good adaptability to cathodes are the important prerequisites for the practical application of solid-state electrolytes (SE). In this work, an environment-friendly poly(1,3-dioxolane) (PDOL) solid electrolyte membrane was for the first-time prepared by a rapid surface-initiating 1,3-dioxolane (DOL) polymeration process under the interaction of substrate and initiator. The -SiO3, -CaO5 and -NaO3 groups on the surface of glass substrate can react with the oxygen atoms on the DOL ring, initiate the rings opening and polymerizing to be long chains under the action of LiPF6, which provides an efficient and environment-friendly preparation method for PDOL membrane without any organic solvent release, and the monomer conversion rate of the DOL reaches 97.6%. This highly polymerized PDOL electrolyte is friendly to the lithium metal environment and shows strong stability, the Li/SE/Li cell can run stably for nearly 4000 h at a c.d. of 0.3 mA/cm2. High electrochem. stability window up to 5.0 V enables PDOL electrolyte friendly adapt to various cathode environments including sulfur (S) and LiFePO4, and LiCoO2 and Li(Ni0.6Co0.2Mn0.2)O2 (NCM622). The assembled NCM622/SE/Li solid-state soft-pack battery can be cycled for 300 cycles at 0.5 C with the capacity retention of 85%. This PDOL electrolyte membrane shows a high promising com. application prospect due to its friendly and high-efficiency polymerization process and strong adaptability to electrodes.2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) were involved in the experimental procedure.

The article contains the following contents:

River and coastal sediments were collected at 17 stations in Ulsan, the largest industrial city in South Korea, to evaluate the levels, profiles, emission sources, and spatial distribution of polycyclic aromatic hydrocarbons (PAHs). The mean concentration of Σ₁₆ PAHs was 722 ng/g, and fluoranthene was a predominant compound PAHs with 4-6 rings showed higher proportions than PAHs with 2-3 rings. The stations located near industrial complexes showed elevated levels of indicator compounds for petroleum, coal, coke, and fuel combustion. Therefore, petrochem. industries, coal pier, non-ferrous industries, and vehicles were identified as the emission sources. As industrialization and urbanization progressed, an increase in PAH levels and profile changes were observed as a result of the increasing industrial fuel consumption and the increasing number of vehicles. This is the first study that confirmed the change of PAHs in sediment caused by the change of emission sources over time in Ulsan. And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.

Targeting Bcr-Abl is the key to the treatment of chronic myeloid leukemia. Despite great progress in the treatment of patients with chronic CML, advanced CML patients are still unable to obtain effective and safe drugs. Momordica cochinchinensis seed is the dried ripe seed of Momordica cochinchinensis, which is a kind of fruit and consumed for dietary as well as medicinal uses. This study aimed to investigate the anticancer activity of Momordica cochinchinensis seed extract (MCSE) in CML cells. CML cells (KBM5 and KBM5-T315I) were treated with MCSE and analyzed for growth, apoptosis, and signal transduction. Nude mouse xenograft model was used to evaluate the antitumor activity of MCSE In Vivo. MCSE significantly reduced the cell viability of CML cells, triggered G0/G1 phase arrest in KBM5 cells and S phase arrest in KBM5-T315I cells. Concurrently, MCSE caused the activation of caspase-3, -8, -9, PARP and the degradation of Mcl-1, ultimately triggering endogenous and exogenous cell apoptosis. Meanwhile, MCSE downregulated Bcr-Abl levels and its downstream signaling pathways. Addnl., MCSE inhibited the growth of CML cells in nude mouse xenografts. Taken together, this study demonstrated the anticancer mechanism of MCSE, namely blocking Bcr-Abl and downregulating Mcl-1, and finally induced apoptosis of CML cells. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .

Song, Kai;Ren, Xu;Zhang, Qiaoyun;Xu, Linghan;Liu, Dan published 《Electrochemical treatment for leachate membrane retentate: Performance comparison of electrochemical oxidation and electro-coagulation technology》. The research results were published in《Chemosphere》 in 2022.HPLC of Formula: 119-47-1 The article conveys some information:

With the widespread use of membrane in advanced treatment of leachate, China produces a large amount of leachate membrane retentate (LMR) (23.4 million tons) annually, which is usually treated by incineration or recirculation in engineering, but these technologies have many drawbacks. LMR is suitable for electrochem. treatment due to its high elec. conductivity This study compared the performances of electrochem. oxidation (EO) and electro-coagulation (EC) technol. on LMR treatment under different exptl. conditions, including anode material, c.d., initial pH and reaction time. We found that EO optimal conditions achieved 70.1%, 83.1%, 78.7%, 98.7%, and 69.7% removal of total organic carbon (TOC), UV absorption (at 254 nm), chromaticity, ammonia nitrogen (NH₃-N), and total nitrogen (TN), resp. Compared with EO, EC exhibited a similar removal ability for organics and better removals of chroma, but much less performance for removing nitrogen pollutants in the same reaction time, i.e., removals of NH₃-N and TN were only 31.5% and 36.2%, resp. Meanwhile, EC showed much higher instantaneous current efficiency of COD than EO under its optimal reaction time (120 min). In addition, the UV-Vis spectra and 3D fluorescence spectra indicated that EO exhibited relatively outstanding performance in decomposing dissolved organic matter (DOM) with rather complicated structures than EC. Also, the flow field-flow fractionation technique demonstrated that EO preferentially destroy humic-like, large mol. weight DOM, and converting them to smaller mols., which resulted in more volatile organic compounds in EO samples than EC samples. While EC had little selectivity in the removal of organics, except humic-like DOM with relative small mol. These findings can provide a theor. basis for the electrochem. treatment of LMR. And 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) was used in the research process.

The article contains the following contents:

Thioredoxin, a highly conserved class of proteins involved in redox signaling, is found in a range of organisms from bacteria to higher-level eukaryotes. Thioredoxin acts as an active regulatory enzyme to eliminate excessive reactive oxygen species, thereby preventing cellular damage. In this study, the cDNA sequence of thioredoxin domain-containing 5 (AbTXNDC5) from the disk abalone transcriptomic database was characterized. An in silico anal. of AbTXNDC5 was performed, and its spatial and temporal expression patterns in hemocytes and gills in response to bacteria (Vibrio parahaemolyticus, Listeria monocytogenes), viral hemorrhagic septicemia virus, and pathogen-associated mol. pattern mols. were observed Furthermore, AbTXNDC5 expression was examined in different developmental stages. Functional assays to explore insulin disulfide reduction, anti-apoptotic activity, and protection against hypoxic cell death of AbTXNDC5 were conducted through recombinant proteins or overexpression in cells. AbTXNDC5 contains a 1179-bp open reading frame coding for 392 amino acids. Conserved thiol-disulfide cysteine residues within two Cys-X-X-Cys motifs were found in AbTXNDC5. Quant. real-time polymerase chain reaction indicated that healthy digestive tract and hemocyte tissues expressed high levels of AbTXNDC5 mRNA, which may protect the host from invading pathogens. Immune-challenged abalone hemocytes and gills exhibited upregulated expression of AbTXNDC5 at different time points. rAbTXNDC5 also exhibited a functional insulin disulfide reductase activity. AbTXNDC5 conferred protection to cultured cells from apoptosis and hypoxia-induced stress, compared to the pcDNA3.1(+) transfected control cells. Therefore, AbTXNDC5 can be considered an important gene in abalones in relation to the primary immune system and regulation of redox homeostasis and confers protection from stress.

The article was appeared in 《Environmental Science & Technology Letters》. They have made some progress in their research.Synthetic Route of C23H32O2 The article mentions the following:

The prevalently used LC-MS/MS methods for the simultaneous determination of synthetic phenol antioxidants (SPAs) and relevant metabolites suffer from a serious drawback of low sensitivity for 2,6-di-tert-butyl-4-hydroxytoluene (BHT) and a common issue of background contamination, which hampers the simple and accurate detection of these substances at trace levels in environmental samples. In this study, we developed an improved LC-MS/MS method for the simultaneous determination of eight SPAs and four relevant metabolites, including BHT. By use of atm. pressure chem. ionization (APCI), the sensitivity of BHT in the LC-MS/MS was enhanced approx. 260 times vs. results obtained by using electrospray ionization (ESI), which allowed the anal. of BHT up to 1.1 ng/g in indoor dust and 0.06 ng/g in human plasma. Similarly, the sensitivity of 2,4,6-tri-tert-butylphenol and 2,6-di-tert-butyl-4-sec-butylphenol was also enhanced with APCI, which avoided their sep. anal. by GC-MS. By installation of a C₁₈ column after the eluent mixer and before the injector as a trap column, the target analytes leached out from the LC system were eluted at a much later retention time than those in the samples, which resulted in complete elimination of the instrumental background contamination. These improvements enable the method to be well applied to the real samples. The experimental procedure involved many compounds, such as 2,2-Methylenebis(6-tert-butyl-p-cresol) (cas: 119-47-1) .
