Yang, Wei published the artcileStructure-activity relationship studies of phenothiazine derivatives as a new class of ferroptosis inhibitors together with the therapeutic effect in an ischemic stroke model, Application In Synthesis of 338454-30-1, the publication is European Journal of Medicinal Chemistry (2021), 112842, database is CAplus and MEDLINE.

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.

Hu, Liqun published the artcileAn Intermolecular Hydroarylation of Highly Deactivated Styrenes Catalyzed by Re₂O₇/HReO₄ in Hexafluoroisopropanol, Synthetic Route of 91-16-7, the publication is ACS Catalysis (2022), 12(10), 5857-5863, database is CAplus.

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.

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.

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.

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.

Rearrangement of highly reactive nitrile imines derived from N-2-nitrophenyl hydrazonyl bromides could be harnessed for the facile construction of amide bonds was reported. This amidation reaction was found to be widely applicable to the synthesis of primary, secondary, and tertiary amides and was used as the key step in the synthesis of the lipid-lowering agent bezafibrate. The orthogonality and functional group tolerance of this approach was exemplified by the N-acylation of unprotected amino acids.

Fliri, Anton F. published the artcileDrug effects viewed from a signal transduction network perspective, Related Products of ethers-buliding-blocks, the publication is Journal of Medicinal Chemistry (2009), 52(24), 8038-8046, database is CAplus and MEDLINE.

Understanding how drugs affect cellular network structures and how resulting signals are translated into drug effects holds the key to the discovery of medicines. Herein we examine this cause-effect relationship by determining protein network structures associated with the generation of specific in vivo drug-effect patterns. Medicines having similar in vivo pharmacol. have been identified by a comparison of drug-effect profiles of 1320 medicines. Protein network positions reached by these medicines were ascertained by examining the coinvestigation frequency of these medicines and 1179 protein network constituents in millions of scientific investigations. Interestingly, medicine associations obtained by comparing by drug-effect profiles mirror those obtained by comparing drug-protein coinvestigation frequency profiles, demonstrating that these drug-protein reachability profiles are relevant to in vivo pharmacol. By using protein associations obtained in these investigations and independent, curated protein interaction information, drug-mediated protein network topol. models can be constructed. These protein network topol. models reveal that drugs having similar pharmacol. profiles reach similar discrete positions in cellular protein network systems and provide a network view of medicine cause-effect relationships.

Nielsen, Daniel S. published the artcileHigh Cell Permeability Does Not Predict Oral Bioavailability for Analogues of Cyclic Heptapeptide Sanguinamide A*, Category: ethers-buliding-blocks, the publication is Australian Journal of Chemistry (2020), 73(4), 344-351, database is CAplus.

The cyclic heptapeptide derivative, sanguinamide A, is a model scaffold for studying how component amino acids, heterocycles, and N-methylation influence membrane permeability and oral bioavailability. Membrane permeable sanguinamide A analogs have been reported, but there is limited data on their pharmacokinetic properties in vivo. Here we report pharmacokinetic properties for highly cell and membrane permeable sanguinamide A analogs in rats and find that there is no correlation between reported permeability in vitro and oral bioavailability in vivo. We show that N-methylation of sanguinamide A analogs gives compounds with greater flexibility, greater susceptibility to degradation by rat liver microsomes, and lower oral bioavailability in rats.

Herold-Majumdar, Owik Matthias published the artcileRemoval of hard COD from acidic eucalyptus kraft pulp bleach plant effluent streams using oxidoreductases, Quality Control of 134-96-3, the publication is Biotechnology and Applied Biochemistry (2022), 69(2), 687-700, database is CAplus and MEDLINE.

The bleach plant of a pulp and paper (P&P) mill presents a major source of wastewater containing toxic organic matter characterized as COD (COD). Due to their high oxidizing power, oxidoreductases hold promise to be a key solution for the removal of dissolved organic material. Here, four oxidoreductases from different enzyme families were selected to treat bleach plant effluents. Haloperoxidase treatment of the final effluent resulted in the highest levels of decolorization (71%) and reduction of aromatic compounds (36%). Using single compound anal., 27 low mol. weight compounds were found to be persistent throughout the wastewater treatment process and, therefore, classified as hard COD. The tested enzymes efficiently removed several of the identified COD compounds Hence, this study suggests that the application of oxidoreductases will serve as an environmental-friendly solution for reducing waste from P&P production
