We developed a high-throughput assay for modulators of mitochondrial function in neurons measuring inner mitochondrial membrane potential (ΔΨ_m) and ATP production The assay was used to screen a library of small mols., which led to the identification of structural/functional classes of mitochondrial modulators such as local anesthetics, isoflavones, COXII inhibitors, adrenergic receptor blockers, and neurotransmitter system effectors. Our results show that some of the isolated compounds promote mitochondrial health, enhance oxygen consumption rate, and protect neurons against toxic insults found in the cellular environment of Alzheimer disease. These studies offer a set of compounds that may provide efficacy in protecting the mitochondrial system in neurodegenerative disorders.

Li, Xiao-Chang published the artcileSynthesis, Properties, and Application of New Luminescent Polymers with Both Hole and Electron Injection Abilities for Light-Emitting Devices, HPLC of Formula: 146370-51-6, the publication is Chemistry of Materials (1999), 11(6), 1568-1575, database is CAplus.

New luminescent polymers that contain both electron-withdrawing cyano groups and electron-rich moieties, triphenylamine (TPA) or tetraphenyldiaminobiphenyl (TPD), were synthesized by Knoevenagel condensation of 1,4-bis(cyanomethyl)-2-[(2-ethylhexyl)oxy]-5-methoxybenzene with the dialdehyde of TPA or TPD, resp. The polymers were characterized by NMR, FT-IR, microanal., GPC, DSC, and TGA. Efficient orange photoluminescence was observed with an absolute quantum efficiency of 48% for the TPA incorporated polymer (TPA-CNPPV). Cyclic voltammetry investigation showed that the polymers presented reversible oxidation and reduction with relatively low potentials, which suggested that the polymers have both good electron and hole injection abilities. We demonstrated an effective approach to synthesize polymers with the triad properties of efficient photoluminescence, good hole injection and high electron-affinity properties, which are highly desirable for application in light-emitting devices. This point was supported by the demonstration of a single layer light-emitting device with a configuration of ITO/TPA-CNPPV/Al, in which good external quantum efficiency (0.1%) and bright luminance of 2100 cd/m² was achieved. Multilayer LEDs using the polymers as the active layers and different charge injection/transporting layers were also investigated.

Lin, Dan-Dan published the artcileStimulation of Bathyarchaeota in enrichment cultures by syringaldehyde, 4-hydroxybenzaldehyde and vanillin under anaerobic conditions, HPLC of Formula: 134-96-3, the publication is International Biodeterioration & Biodegradation (2022), 105409, database is CAplus.

Bathyarchaeota covering about 25 subgroups are a newly discovered archaeal phylum with widespread in anaerobic environments including marine sediments, soils and subsurface petroleum reservoirs. Although recent studies showed that Bathyarchaeota can use lignin as an energy source to get enrichment, there is a lack of the pure culture and thus the understanding about Bathyarchaeota is still based on genomic information. In this study, lignin and three aldehyde compounds, namely syringaldehyde, 4-hydroxybenzaldehyde, and vanillin, which were recognized as the metabolic intermediates of lignin biodegradation, were used as substrates to enrich Bathyarchaeota from mangrove sediments, and enrichment cultures of Bathyarchaeota was successfully established in the laboratory The changes in gene-copy numbers, microbial composition and consumption of the substrates indicated that the syringaldehyde significantly stimulated the growth of Bathyarchaeota in the enrichment culture. Meanwhile, the relative abundance of Bathyarchaeota was as high as 97.13% in term of the archaeal composition, especially bathyarchaeotal genome subgroup-6 accounted for more than 99.9% in Bathyarchaeota, and 4.74 mmol L^-1 methane were also detected in the enrichment culture amended with syringaldehyde as a substrate after about 117 days of incubation, compared to 4-HBA (3.75 mmol L^-1) and VA (3.75 mmol L^-1). This work will facilitate the design of high-efficiency enrichment cultures and understanding about the metabolic and ecol. functions of Bathyarchaeota in nature.

Here, authors describe an activation mode for unactivated alkenes on the basis of a synergy between Re₂O₇/HReO₄ and hexafluoroisopropanol (HFIP). Highly electron-deficient styrenes have been activated to effect a challenging intermol. hydroarylation with different arenes to give a variety of diarylalkanes in high efficiency. This method is characterized by mild reaction condition, broad substrate scope, high chem. yields, and minimal waste generation. The potential synthetic application of this methodol. was exemplified by the efficient synthesis of a retinoic acid receptor (RAR) agonist. DFT calculations and deuterium-labeling experiments were conducted to elucidate the reaction mechanism, and both confirmed the critical role of HFIP, which significantly reduced the energetical barriers for several key steps of this transformation via a network of hydrogen bonding to perrhenate anion with two equivalent of HFIP.

Ferroptosis is a new type of programmed cell death discovered recently and has been demonstrated to be involved in a number of human diseases such as ischemic stroke. Ferroptosis inhibitors are expected to have potential to treat these diseases. Herein, we report the identification of promethazine derivatives as a new type of ferroptosis inhibitors. Structure-activity relationship (SAR) analyses led to the discovery of the most potent compound 2-(1-(4-(4-methylpiperazin-1-yl)phenyl)ethyl)-10H-phenothiazine (51), which showed an EC₅₀ (half maximal effective concentration) value of 0.0005μM in the erastin-induced HT1080 cell ferroptosis model. In the MCAO (middle cerebral artery occlusion) ischemic stroke model, 51 presented an excellent therapeutic effect. This compound also displayed favorable pharmacokinetic properties, in particular, a good ability to permeate the blood-brain barrier. Overall, 51 could be a promising lead compound for the treatment of ferroptosis related diseases and deserves further investigations.

Zou, Wen published the artcileEnhancement of the visible-light absorption and charge mobility in a zinc porphyrin polymer/g-C₃N₄ heterojunction for promoting the oxidative coupling of amines, Recommanded Product: (2-Methoxyphenyl)methanamine, the publication is Applied Catalysis, B: Environmental (2021), 119863, database is CAplus.

Graphitic carbon nitride (g C₃N₄, CN) has been widely used as a photocatalyst due to its high stability and suitable band gap. However, its further development is limited due to inefficient light harvesting and rapid recombination of photogenerated carriers. In this study, a visible-light-responsive zinc porphyrin (ZnP)/CN heterojunction photocatalyst was synthesized by the combination of CN and a zinc-porphyrin-conjugated microporous polymer (ZnP-CMP). ZnP/CN exhibited excellent photocatalytic activity for the oxidative coupling of amines to imines under visible-light irradiation The efficiency of the as-developed photocatalyst was 25 times greater than that of CN and about 2 times greater than that of ZnP-CMP. The significantly enhanced catalytic efficiency was attributed to the promotion of visible-light harvesting and photogenerated charge mobility via the introduction of ZnP-CMP. The ZnP/CN heterojunction photocatalyst also exhibited excellent broad substrate scope, stability, and reusability.

Jiang, Jun published the artcileDonor-Acceptor Type Conjugated Microporous Polymer as a Metal-Free Photocatalyst for Visible-Light-Driven Aerobic Oxidative Coupling of Amines, Category: ethers-buliding-blocks, the publication is Catalysis Letters (2021), 151(11), 3145-3153, database is CAplus.

Developing cheap, highly efficient, metal-free heterogeneous photocatalysts remain a great challenge in photoredox reactions. Herein, we utilize a typical Suzuki coupling of low-cost triphenylamine derivative and 9,10-dibromoanthracene to synthesis a donor-acceptor type conjugated microporous polymer (denoted as PAA-CMP). As expected, heterogeneous PAA-CMP exhibits excellent photocatalytic performance, good functional group tolerance and satisfying recyclability in metal-free aerobic oxidative coupling of amines to imines driven by visible light, which is due to its absolute energy level positions and good physicochem. stability. More excitingly, PAA-CMP can enable the gram-scale air-oxidized photocatalytic conversion under natural sunlight irradiation, yielding the desired imine product with an isolated yield of 65% for 48 h. The current work provides a great application prospect for CMPs in low-cost and large-scale organic industrial production in the future. The prepared donor-acceptor (D-A) type conjugated microporous polymer (PAA-CMP) as a metal-free and heterogeneous photocatalyst enable the gram-scale air-oxidized photocatalytic conversion of benzylamine into N-benzylidenebenzylamine under natural sunlight irradiation, yielding the desired imine product with an isolated yield of 65%.

The orderly mesoporous KF/Al-Ce-SBA-15 (KF/ACS) solid bases were successfully prepared with cetyltrimethylammonium bromide (CATB)- poly (ethylene oxide)/poly (propylene oxide)/poly (ethylene oxide) triblock copolymer (P123) as the dual-template and KF as the modifier in two steps. The structure and property of the obtained catalysts were characterized by X-ray diffraction (XRD), N₂ adsorption-desorption, transmission electron microscopy (TEM), SEM (SEM) and CO₂-temperature programmed desorption (TPD). The results illustrated that the KF/ACS catalysts possess both an ordered mesostructure and superbasicity when the introduced Al/Ce at. ratio is 0.12 and the loading amounts (mass fraction) of KF is 10%. The catalytic activity of the prepared materials was evaluated in the ring-opening reaction of propylene oxide (PO) with methanol. It shows excellent catalytic performance exhibiting 92.0% yield of propylene glycol monomethyl ether (PM) and 96.1% selectivity to 1-methoxy-2-propanol (PPM) and the byproducts of dipropylene glycol Me ether was effectively inhibited.

Ma, Zhiming published the artcileCoexistence of Fe Nanoclusters Boosting Fe Single Atoms to Generate Singlet Oxygen for Efficient Aerobic Oxidation of Primary Amines to Imines, Category: ethers-buliding-blocks, the publication is ACS Catalysis (2022), 12(9), 5595-5604, database is CAplus.

Tuning the geometric and electronic structure of the single-metal-atom catalysts via simultaneous presence of metal nanoparticles or nanoclusters (NCs) offers an alternative avenue to improving their catalytic performance. Herein, that the coexistence of Fe NCs in proximity to Fe single atoms on N-doped porous carbon can significantly improve the catalytic performance in aerobic oxidation of primary amines to imines using air as the oxidant was demonstrate. A broad spectrum of primary aromatic, heterocyclic, and aliphatic amines was efficiently and selectively oxidized into their corresponding imines in good to high yields. Exptl. measurements and theor. calculations reveal that the proximity of Fe NCs interacts with Fe single atoms, which not only benefits the adsorption of mol. O₂ and amine substrates but also promotes the activation of O₂ to selectively generate singlet oxygen (¹O₂) and then facilitates the key intermediate imine formation via H-atom abstraction with a lower energy barrier, thereby significantly boosting the reaction activity.
