Nakkala, Jayachandra Reddy published the artcileDimethyl Itaconate-Loaded Nanofibers Rewrite Macrophage Polarization, Reduce Inflammation, and Enhance Repair of Myocardic Infarction, Synthetic Route of 617-52-7, the publication is Small (2021), 17(17), 2006992, database is CAplus and MEDLINE.

Cellular metabolism plays a major role in the regulation of inflammation. The inflammatory macrophages undergo a wide-range of metabolic rewriting due to the production of significant amount of itaconate metabolite from cis-aconitate in the tricarboxylic acid cycle. This itaconate mol. has been recently described as a promising immunoregulator. However, its function and mode of action on macrophages and tissue repair and regeneration are yet unclear. Herein, the itaconate-derivative di-Me itaconate (DMI) suppresses the IL-23/IL-17 inflammatory axis-associated genes and promotes antioxidant nuclear factor erythroid 2-related factor 2 target genes. The poly-ε-caprolactone (PCL)/DMI nanofibers implanted in mice initially maintain inflammation by suppressing anti-inflammatory activity and particular inflammation, while at later stage promotes anti-inflammatory activity for an appropriate tissue repair. Furthermore, the PCL/DMI nanofiber patches show an excellent myocardial protection by reducing infarct area and improving ventricular function via time-dependent regulation of myocardium-associated genes. This study unveils potential DMI macrophage modulatory functions in tissue microenvironment and macrophages rewriting for proper tissue repair.

Mo, Yuan published the artcilePhoto-curing of thick monomer systems with photoluminescent ZnO nanoparticles photoinitiators, Formula: C15H20O6, the publication is Progress in Organic Coatings (2022), 106788, database is CAplus.

The photo-curing of thick monomer systems or coatings had often been limited to the depth of a few microns to few millimeters. In order to overcome this difficult problem, the ZnO nanoparticles (NPs) were researched to improve the photo-curing depth because that ZnO had the function of the photoluminescent upon the light irradiation The light emitted by ZnO NPs penetrated into the deeper layers to increase the photo-curing depth. The best co-photoinitiator, bis (2,4,6-trimethylbenzoyl) Ph phosphine oxide (819), in the monomer 1, 6-hexanediol diacrylate, were determined by the UV-visible spectrophotometer and fluorescence spectrophotometer. A photo-curing depth of 16.7 mm was achieved by the combination of ZnO NPs and bis (2,4,6-trimethylbenzoyl) Ph phosphine oxide (819) in 1, 6-hexanediol diacrylate. In addition, an exptl. model was proposed, the influence factors were systematically studied, and the exptl. equations related to the different factors and photo-curing depths were determined by controlling the different variables. With different variables, the maximum top layer double bond conversion of 77%, and the maximum bottom layer double bond conversion of 55%. This investigation confirmed that the photoluminescent ZnO NPs had a function of improving the photo-curing depth. Therefore, this investigation provided a new idea and method for the photo-curing of thick monomer systems and coatings.

Leucine-rich repeat kinase 2 (LRRK2) has been implicated in the pathogenesis of Parkinson’s disease (PD). Inhibition of LRRK2 kinase activity is a therapeutic approach that may lead to new treatments for PD. Herein we report the discovery of a series of [1,2,4]triazolo[4,3-b]pyridazines that are potent against both wild-type and mutant LRRK2 kinase activity in biochem. assays and show an unprecedented selectivity towards the G2019S mutant. A structural rational for the observed selectivity is proposed.

Chen, Haifeng published the artcileFormation of allylated quaternary carbon centers via C-O/C-O bond fragmentation of oxalates and allyl carbonates, Computed Properties of 5205-11-8, the publication is Chemical Communications (Cambridge, United Kingdom) (2020), 56(3), 454-457, database is CAplus and MEDLINE.

Disclosed herein emphasizes Fe-promoted cross-electrophile allylation of tertiary alkyl oxalates with allyl carbonates that generates all C(sp³)-quaternary centers. The reaction involves fragmentation of tertiary alkyl oxalate C-O bonds to give tertiary alkyl radical intermediates, addition of the radicals to less hindered alkene terminals, and subsequent cleavage of the allyl C-O bonds. Allylation with 2-aryl substituted allyl carbonates was mediated by Zn/MgCl₂, and Fe was used to promote the radical addition efficiency. By introduction of activated alkenes, a three-component radical cascade reaction took place.

Hang, Wei published the artcileCobalt-Catalyzed Reductive Carboxylation of Aryl Bromides with Carbon Dioxide, Recommanded Product: 3-(Methoxycarbonyl)benzoic acid, the publication is Advanced Synthesis & Catalysis (2020), 362(12), 2337-2341, database is CAplus.

Cobalt-catalyzed reductive carboxylation of aryl bromides with carbon dioxide to form the corresponding carboxylic acids ArC(O)OH [Ar = Ph, 4-MeOC₆H₄, 1-naphthyl, etc.] in good to high yields was developed. The reaction proceeded under one atm pressure of CO₂ at 40°C in the presence of cobalt iodide/2,2′-bipyridine catalysts and zinc dust as a reducing reagent. Preliminary mechanistic experiments ruled out intervention of intermediate organozinc species for carboxylation with CO₂, thus suggested direct CO₂ insertion into the corresponding ArCoBr species.

Yildirim, Hatice published the artcileNatural-product-inspired design and synthesis of thiolated coenzyme Q analogs as promising agents against Gram-positive bacterial strains: insights into structure-activity relationship, activity profile, mode of action, and molecular docking, Name: Ethyl 2-mercaptopropanoate, the publication is RSC Advances (2022), 12(32), 20507-20518, database is CAplus and MEDLINE.

In an attempt to develop effective and potentially active antibacterial and/or antifungal agents, we designed, synthesized, and characterized thiolated CoQ analogs (CoQ1-8) with an extensive antimicrobial study. The antimicrobial profile of these analogs was determined using four Gram-neg. bacteria, three Gram-pos. bacteria, and three fungi. Because of the fact that the thiolated CoQ analogs were quite effective on all tested Gram-pos. bacterial strains, including Staphylococcus aureus (ATCC 29213) and Enterococcus faecalis (ATCC 29212), the first two thiolated CoQ analogs emerged as potentially the most desirable ones in this series. Importantly, after the evaluation of the antibacterial and antifungal activity, we presented an initial structure-activity relationship for these CoQ analogs. In addition, the most promising thiolated CoQ analogs (CoQ1 and CoQ2) having the lowest MIC values on all tested Gram-pos. bacterial strains, were further evaluated for their inhibition capacities of biofilm formation after evaluating their in vitro potential antimicrobial activity against each of 20 clin. obtained resistant strains of Gram-pos. bacteria. CoQ1 and CoQ2 exhibited potential mol. interactions with S. aureus DNA gyrase in addition to excellent pharmacokinetics and lead-likeness profiles. Our findings offer important implications for a potential antimicrobial drug candidate, in particular for the treatment of infections caused by clin. resistant MRSA isolates.

Yu, Hui published the artcileEvaluation of “Click” Binaphthyl Chiral Stationary Phases by Liquid Chromatography, Related Products of esters-buliding-blocks, the publication is Chirality (2012), 24(5), 391-399, database is CAplus and MEDLINE.

Two click binaphthyl chiral stationary phases were synthesized and evaluated by liquid chromatog. Their structures incorporate S-(-)-1,1′-binaphthyl moiety as the chiral selector and 1,2,3-triazole ring as the spacer. These chiral stationary phases (CSPs) allowed the efficient resolution for a wide range of racemic BINOL derivatives, particularly for nonpolar diether derivatives and 3-Ph indolin-2-one analogs. The chromatog. data showed that the π-π interaction was crucial for enantiorecognition of these CSPs. Loss of enantioselectivity observed on CSP3, which are lacking the triazole ring linkage, indicated that the triazole ring linkage took part in the enantioseparation process, although it was remote from the chiral selector of the CSP. The substitution of the Ph group at 6 and 6′ positions can significantly improve the separation ability of the CSP. The chiral recognition mechanism was also studied by tracking the elution orders and studying the thermodn. parameters. Chirality 00:000-000, 2012. Copyright © 2012 Wiley Periodicals, Inc.

Su, Yifan published the artcilePreparation and properties of ethylene-acrylate salt ionomer/polypropylene antistatic alloy, Product Details of C42H63O3P, the publication is Advanced Composites and Hybrid Materials (2021), 4(1), 104-113, database is CAplus.

Ethylene-acrylate salt ionomer antistatic agent was prepared with ethylene-Et acrylate copolymer and potassium hydroxide as the primary raw materials and blended with polypropylene (PP) to make self-made ionomer/PP antistatic alloy. Com. Entira and PP were blended in the same way to prepare Entira/PP antistatic alloy. Then, the morphol. and phys. properties of the self-made ionomer/PP and Entira/PP were studied using differential scanning calorimetry, thermo-gravimetric anal., rotary rheometer, and scanning electron microscope. The exptl. results showed the development of a self-made ionomer in a torque rheometer successfully, and its performance in all aspects was similar to the com. Entira. Material test results have shown that the phys. properties such as surface and volume resistivity, antistatic durability, thermal weight loss, crystallization properties, and rheol. properties of PP modified by self-made ionomer are very similar to those modified by Entira. And due to the selection of raw materials, this self-made ionic antistatic agent is cheaper than com. Entira and has good research value. A permanent antistatic agent was prepared by the saponification reaction of ethylene-Et acrylate copolymer and KOH. This antistatic agent can reduce the resistivity of PP by 8 orders of magnitude, showing an antistatic effect similar to that of com. Entira.
