Quan, Wei published the artcileMetabolic perturbations and health impact from exposure to a combination of multiple harmful Maillard reaction products on Sprague-Dawley rats, Computed Properties of 526-98-7, the publication is Food & Function (2022), 13(10), 5515-5527, database is CAplus and MEDLINE.

The present study aimed to investigate the metabolic perturbations and health impact of the co-accumulation of Maillard reaction products (MRPs), including acrylamide, harmane, and Nε-(carboxymethyl)lysine (CML), via serum biochem. and histopathol. examinations as well as metabolomic anal. Sprague-Dawley rats were treated with acrylamide (2 mg per kg body weight [bw]), harmane (1 mg per kg bw), CML (2 mg per kg bw), and combinations of these MRPs. Harmane did not cause adverse effects on the health of rats, whereas acrylamide and CML resulted in significantly (P < 0.05) decreased insulin sensitivity (HOMA-IR > 1), increased oxidative stress levels, and pathol. injuries to the pancreas, liver, and gastrocnemius. Owing to the antioxidant and anti-diabetic activities of harmane, the effects of the combination of the MRPs on oxidative stress levels, blood glucose metabolism, and pathol. injuries to the pancreas and gastrocnemius were relieved. However, new health problems, including pathol. injury of the kidneys and increased cancer risk, were observed Metabolomic anal. revealed that this may be related to the effects of MRPs on the arginine biosynthesis pathway, which resulted in the abnormal metabolism of fumaric acid and the tricarboxylic acid cycle. These results indicated that the mechanisms of the combined effect of MRPs and their effects on health cannot be predicted from the effects of individual MRPs.

Durben, Stefan published the artcileDithienophosphole-capped π-conjugated oligomers, Recommanded Product: 5,5′-Bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2,2′-bithiophene, the publication is New Journal of Chemistry (2010), 34(8), 1585-1592, database is CAplus.

The synthesis of a 2-monobrominated dithieno[3,2-b:2′,3′-d]phosphole has opened the access to a series of highly luminescent π-conjugated oligomers that link two dithienophosphole units via a variety of aromatic spacers. The nature of the linking mode was found to have a significant impact on the photophys. properties of the system as a whole, either considerably improving the molar absorptivity of the new extended chromophores, or providing luminescent materials with red-shifted emission features and substantial photoluminescence quantum yields.

Oligoantennary neoglycoconjugates can act as powerful inhibitors of carbohydrate-protein interactions and thus serve as anti-adhesives in carbohydrate-based adhesion systems. They were obtained by a procedure that does not require protecting groups. Various unprotected NCS-functionalized saccharides were coupled with oligoamines in aqueous solution This versatile method is generally applicable to the synthesis of thiourea-bridged glycodendrimers.

Yamaguchi, Shigehiro published the artcileChanges of organized solution (microemulsion) structure with small change in amphiphile composition, Formula: C11H24O3, the publication is Yukagaku (1989), 38(2), 157-60, database is CAplus.

In the system of 8 weight% CaCl₂ aqueous/C₁₂H₂₅OCH₂CH₂SO₄Ca_0.5/iso-C₈H₁₇OCH₂CH(OH)CH₂OH/decane with only 3 weight% of total amphiphiles, it was possible to obtain only one phase region of microemulsion whose solvents swelled by 97 weight% (water + oil). The composition of water and oil varied over the entire range with slight changes in the amphiphile ratio from 0.38 to 0.42. Self-diffusion measurements indicated the microemulsion microstructure changed from O/W (hydrophilic) to W/O (lipophilic) by varying the HLB of the amphiphiles. A comparison of these results with change in temperature in a nonionic surfactant system showed that the change in the ratio of hydrophilic amphiphile and lipophilic amphiphile (from 0.38 to 0.42) had the same effect as that in HLB as making the temperature 30° in the nonionic surfactant system.

Zhou, Pan published the artcileMolybdenum-Catalyzed Cross-Coupling of Benzyl Alcohols: Direct C-OH Bond Transformation via [2 + 2]-Type Addition and Elimination, Product Details of C19H14O2, the publication is Organic Letters (2022), 24(23), 4218-4223, database is CAplus and MEDLINE.

Traditional cross-couplings catalyzed by transition metal catalysts generally rely on the classic oxidative addition-transmetalation-reductive elimination process, which requires low-valent precious metals and an inert atm. and which initiates from carbon-alide or pesudo carbon-halide bonds. Herein, an unprecedented molybdenum-oxo-complex-catalyzed intermol. cross-coupling of benzyl alcs. has been reported. Various alcs. including primary, secondary, and tertiary substrates can proceed efficiently under these conditions. Several functional groups sensitive to the low-valent transition metals, such as aryl halides, can be well tolerated. The mechanistic studies and DFT calculations suggest that an intramol. concerted cyclization was involved in the reverse [2 + 2]-type elimination process.

Li, Xiaowei published the artcileNickel-Catalyzed Arylation of C(sp³)-O Bonds in Allylic Alkyl Ethers with Organoboron Compounds, Recommanded Product: ((3aS,5aR,8aR,8bS)-2,2,7,7-Tetramethyltetrahydro-3aH-bis([1,3]dioxolo)[4,5-b:4′,5′-d]pyran-3a-yl)methanol, the publication is Organic Letters (2021), 23(17), 6612-6616, database is CAplus and MEDLINE.

A nickel-catalyzed cross-coupling of allylic alkyl ethers with organoboron compounds through the cleavage of the inert C(sp³)-O(alkyl) bonds is described. Several types of allylic alkyl ethers can be coupled with various boronic acids or their derivatives to give the corresponding products in good to excellent yields with wide functional group tolerance and excellent regioselectivity. The gram-scale reaction and late-stage modification of biol. active compounds further prove the practicality of this synthetic method.

Li, Yaowen published the artcileNovel low-bandgap oligothiophene-based donor-acceptor alternating conjugated copolymers: synthesis, properties, and photovoltaic applications, Related Products of alcohols-buliding-blocks, the publication is Journal of Polymer Science, Part A: Polymer Chemistry (2010), 48(13), 2765-2776, database is CAplus.

A series of novel soluble donor-acceptor low-bandgap-conjugated polymers consisting of different oligothiophene (OTh) coupled to electron-accepting moiety 2-pyran-4-ylidenemalononitrile (PM)-based unit were synthesized by Stille or Suzuki coupling polymerization The combination of electron-accepting PM building block with varied OTh_n (the number of thiophene unit increases from 3 to 5) results in enhanced π-π stacking in solid state and intramol. charge transfer (ICT) transition, which lead to an extension of the absorption spectra of the copolymers. Cyclic voltammetry measurements and MO distribution calculations indicate that the highest occupied MOs (HOMO) energy levels could be fine-tuned by changing the number of thiophene units of the copolymers, and the resulting copolymers possessed relatively low HOMO energy levels promising good air stability and high-open circuit voltage (V_oc) for photovoltaic application. Bulk heterojunction photovoltaic devices were fabricated by using the copolymers as donors and (6,6)-Ph C₆₁-butyric acid Me ester as acceptor. The highest V_oc reached 0.94 V, and the short circuit currents (J_sc) were improved from 1.78 to 2.54 mA/cm², though the power conversion efficiencies of the devices were measured between 0.61 and 0.99% under simulated AM 1.5 solar irradiation of 100 mW/cm², which indicated that this series copolymers can be promising candidates for the photovoltaic applications.

Wang, Cheng published the artcileIdentifying Key Metabolites Associated with Glucosinolate Biosynthesis in Response to Nitrogen Management Strategies in Two Rapeseed (Brassica napus) Varieties, Application In Synthesis of 90-64-2, the publication is Journal of Agricultural and Food Chemistry (2022), 70(2), 634-645, database is CAplus and MEDLINE.

A high glucosinolate (GSL) concentration, an undesirable substance, has severely restricted rapeseed (Brassica species) development. We performed widely targeted metabolomics anal. based on the ultra-high-performance liquid chromatog.-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) technol. to analyze the metabolic profiles and identify the differential metabolites and GSL components in response to different nitrogen (N) levels in two rapeseed varieties. A total of 341 metabolites and 38 GSL components were detected in the seeds. A total of 188 differential metabolites, including 34 GSL components, were identified in response to different treatments, which were mapped into 2-oxocarboxylic acid metabolism, tryptophan metabolism, and GSL biosynthesis. Key indicators of GSL components highly responsible for different N levels under two contrasting varieties were recognized, i.e., 1-methylpropyl GSL and 4-methylthiobutyl GSL. This study suggests that the efficient N management and variety selection are important strategies for developing rapeseed with low GSLs.
