Li, Jiafu;Aziz, Tareq Md.;Granger, Caroline O.;Richardson, Susan D. research published 《 Are Disinfection Byproducts (DBPs) Formed in My Cup of Tea? Regulated, Priority, and Unknown DBPs》, the research content is summarized as follows. Globally, tea is the second most consumed nonalcoholic beverage next to drinking water and is an important pathway of disinfection byproduct (DBP) exposure. When boiled tap water is used to brew tea, residual chlorine can produce DBPs by the reaction of chlorine with tea compounds In this study, 60 regulated and priority DBPs were measured in Twinings green tea, Earl Gray tea, and Lipton tea that was brewed using tap water or simulated tap water (nanopure water with chlorine). In many cases, measured DBP levels in tea were lower than in the tap water itself due to volatilization and sorption onto tea leaves. DBPs formed by the reaction of residual chlorine with tea precursors contributed ~12% of total DBPs in real tap water brewed tea, with the remaining 88% introduced by the tap water itself. Of that 12%, dichloroacetic acid, trichloroacetic acid, and chloroform were the only contributing DBPs. Total organic halogen in tea nearly doubled relative to tap water, with 96% of the halogenated DBPs unknown. Much of this unknown total organic halogen (TOX) may be high-mol.-weight haloarom. compounds, formed by the reaction of chlorine with polyphenols present in tea leaves. The identification of 15 haloarom. DBPs using gas chromatog.-high-resolution mass spectrometry indicates that this may be the case. Further studies on the identity and formation of these aromatic DBPs should be conducted since haloarom. DBPs can have significant toxicity.

The transition metal-catalyzed Mizoroki-Heck reaction is a powerful method to synthesize C-C bonds, allowing access to several important pharmaceuticals. Traditionally free amines have not been compatible with these approaches due to oxidation of the amine by the transition metal or other side reactions. However, the functionalization of unprotected allylamines is particularly attractive due to their prevalence in various biol. active mols. Herein, the palladium-catalyzed selective monoarylation of free allylamines using aryl iodides is reported. The strategy works on primary, secondary, and tertiary amines, making it very general. This monoarylation method is scalable and works on aryl iodides with a variety of substituted arene or heterocycle motifs, including chromophoric substrates.

In order to optimize sample preparation for shotgun proteomics, we compared four cysteine alkylating agents: iodoacetamide, chloroacetamide, 4-vinylpyridine and Me methanethiosulfonate, and estimated their effects on the results of proteome anal. Because alkylation may result in methionine modification in vitro, proteomics data were searched for methionine to isothreonine conversions, which may mimic genomic methionine to threonine substitutions found in proteogenomic analyses. We found that chloroacetamide was superior to the other reagents in terms of the number of identified peptides and undesirable off-site reactions. Among the reagents evaluated, iodoacetamide increased the rate of methionine-to-isothreonine conversion, especially if the sample was prepared in gel. The presence of proline following methionine in a protein sequence increased the modification rate as well. Generally, the methionine-to-isothreonine conversion events were relatively rare, but should be taken into account in proteogenomic studies when searching for single nucleotide polymorphism events at the protein level. Addnl., we have evaluated other methionine modifications, such as oxidation and carbamidomethylation. We found that carbamidomethylation may affect up to 80% of peptides containing methionine under the condition of iodoacetamide alkylation. In this case, carbamidomethylation of methionine is more common than oxidation and should be accounted for as a variable modification during proteomic search. One of the most trending questions in bottom-up proteomics is the depth of proteome profiling, in other words, the coverage of proteins by identified tryptic peptides. In proteogenomics, where the identification of a single peptide, e.g. bearing an amino acid substitution, may be of interest, high sequence coverage is especially important. Chem. modifications during sample preparation may mimic biol. significant coding mutations at the proteome level. A typical example of such modification is methionine to isothreonine conversion during alkylation, which mimics methionine to threonine substitution in protein sequences due to resp. genomic mutations. Therefore, the studies on the proper selection of alkylating reagents which balance the cysteine alkylation efficiency and the extent of methionine conversion upon conventional proteomic sample preparation workflow are crucial for the outcome of proteogenomic analyses and should present a general interest for the proteomic community.

Worldwide, iodine deficiency affects two billion people and is the leading preventable cause of intellectual disability. Application In Synthesis of 626-01-7.

Kumao, Ren;Miyatake, Kenji research published 《 Sulfonated and Fluorinated Aromatic Terpolymers as Proton Conductive Membranes: Synthesis, Structure, and Properties》, the research content is summarized as follows. We designed and synthesized a series of sulfonated terpolymers, SPP-PQP and SPP-BQP, containing sulfophenylene, quinquephenylene (QP) and perfluoroalkylene (PAF) or hexafluoroisopropylidene (BAF) groups whose compositions were optimized to achieve high-performance proton conductive membranes. In both series, the terpolymers were obtained as high-mol.-weight (Mn = 19.0-32.9 kDa, Mw = 99.9-198 kDa) providing bendable and transparent membranes with supposed ion exchange capacity (IEC) values (2.41-2.68 meq. g-1) by solution casting. SPP-PQP membranes exhibited higher water uptake, higher proton conductivity, and larger strain at break with increasing the PAF composition In contrast, the membrane properties were less sensitive to the composition in the SPP-BQP membranes. Among the terpolymer membranes investigated, SPP-PQP50 showed the best-balanced properties in terms of low water uptake, high proton conductivity, and high mech. properties probably because highly hydrophobic aliphatic PAF and more rigid QP groups both contributed to those relevant properties. Overall, the combination of different hydrophobic components in the terpolymers was effective in improving the properties of proton conductive membranes, that could not be achieved with the corresponding copolymer membranes.
