Jiang, Hu-Lin published the artcileMannosylated chitosan-graft-polyethylenimine as a gene carrier for Raw 264.7 cell targeting, Application In Synthesis of 96345-79-8, the publication is International Journal of Pharmaceutics (2009), 375(1-2), 133-139, database is CAplus and MEDLINE.

Gene transfer using non-viral vectors is a promising approach for the safe delivery of therapeutic genes. Among non-viral vectors, chitosans have been proposed as alternative, biocompatible cationic polymers for non-viral gene delivery. However, the low transfection efficiency and low specificity of chitosan needs to be addressed prior to clin. application. In this study, mannosylated chitosan-graft-polyethylenimine (Man-CHI-g-PEI) copolymer was prepared by thiourea reaction between the isothiocyanate group of mannopyranosylphenylisothiocyanate and the amine groups of chitosan-graft-PEI (CHI-g-PEI) for targeting into antigen presenting cells (APCs) having mannose receptors. The composition and mol. weight were characterized using ¹H NMR and GPC, resp. The copolymer was complexed with plasmid DNA in various copolymer/DNA (N/P) charge ratios, and the complexes were characterized. Man-CHI-g-PEI showed good DNA binding ability and high protection of DNA from nuclease attack and had low cytotoxicity compared with PEI 25K. The transfection efficiency of Man-CHI-g-PEI/DNA complexes into the Raw 264.7 macrophage cell line, which has mannose receptors, was higher than CHI-g-PEI itself as well as PEI 25K, indicating Man-CHI-g-PEI can be used as an APCs’ targeting gene delivery carrier.

Park, Hyeonjung published the artcileDisintegrable n-Type Electroactive Terpolymers for High-Performance, Transient Organic Electronics, Category: alcohols-buliding-blocks, the publication is Advanced Functional Materials (2022), 32(2), 2106977, database is CAplus.

Degradable organic semiconductors have significant potential for transient and biomedical organic electronics, but there have been only a few studies on fully degradable conjugated polymers (CPs) that achieve high elec. performance. In addition, these examples are limited to p-type CPs. In this study, a series of fully degradable n-type CPs, naphthalene diimide (NDI)-based terpolymer (PNDIT2/IM-f) are developed. The incorporation of an imine linker (IM) into the CP backbone affords the capability of facile hydrolysis degradation while maintaining efficient π-conjugations and excellent elec. properties. An addnl. benefit of this mol. design is the systematic tunability of the degradation characteristics and elec. performance depending on the IM content (f_IM). At the optimal point (f_IM = 0.45) that enables complete degradation of the polymer under acidic conditions, the resulting PNDIT2/IM-0.45 film exhibits high electron mobility (μ_e) of 0.04 cm² V^-1 s^-1 in organic field-effect transistors (OFETs), demonstrating excellent potential as transient OFETs. The high μe value is mainly attributed to the enlarged edge-on orientations and tighter stacking of PNDIT2/IM-f crystallites as increasing f_IM. Thus, this study provides useful guidelines for the design of fully degradable n-type CPs and establishes an important correlation between the mol. structure-electronic performance-transient properties.

Upare, Pravin P. published the artcileA Bimetallic Ru₃Sn₇ Nanoalloy on ZnO Catalyst for Selective Conversion of Biomass-Derived Furfural into 1,2-Pentanediol, Related Products of alcohols-buliding-blocks, the publication is ACS Sustainable Chemistry & Engineering (2021), 9(51), 17242-17253, database is CAplus.

Chemoselective hydrogenolysis of biomass-derived feedstocks into chems. is one of the most challenging transformations for upgrading biomass over noble-metal-based heterogeneous catalysts. Here, we demonstrate the use of an efficient Ru₃Sn₇ alloy-supported ZnO catalyst (Ru-Sn/ZnO) to convert biomass-derived furfural (FF) by selective formation of 1,2-pentanediol (1,2-PDO). We found that 1,2-PDO can be produced with a very high yield (>84%) while limiting the competitive formation of 1,5-PDO (yield of âˆ?2%) and other side hydrogenation reactions during FF hydrogenolysis. The new catalyst showed excellent catalytic performance and catalyst reusability when tested for up to five consecutive cycles without any significant deactivation. The remarkable performance of Ru-Sn/ZnO for selective formation of 1,2-PDO from FF was attributed to the combined effect of Ru₃Sn₇ alloy phases together with tin oxide species on a basic ZnO support. All the tested catalysts were thoroughly characterized through different characterization techniques to confirm the synergy of the active sites in the Ru-Sn/ZnO combination and its effectiveness for selective formation of 1,2-PDO. In addition, a possible reaction mechanism is proposed based on d. functional theory calculations and their correlation with exptl. results.

Boggu, Pulla Reddy published the artcileDiscovery of benzimidazole analogs as a novel interleukin-5 inhibitors, COA of Formula: C4H11NO, the publication is European Journal of Medicinal Chemistry (2019), 111574pp., database is CAplus and MEDLINE.

A series of novel ((hydroxyalkyl)aminomethyl)benzimidazole analogs I [n = 1, 2, 3, 4; R = H, tert-Bu, Ph, etc.; R¹ = H, cyclohexyl, 4-pyridinylmethyl, etc.] and II [R² = Ph, 4-methoxyphenyl, benzyl, 4-methoxybenzyl] were synthesized and evaluated for their IL-5 inhibitory activity using pro-B Y16 cell line. Among them, compound I [n = 1, R = Et, R¹ = H] (94.3% inhibition at 30 μM, IC₅₀ = 3.5 μM, cLogP = 4.132) and compound I [n = 1, R = cyclohexylemthyl, R¹ = H] (94.7% inhibition at 30 μM, IC₅₀ = 5.0 μM, cLogP = 6.253) showed the most potent inhibitory activity. The essential feature of SAR indicated that the chromenone ring can be replaced by a benzimidazole ring to maintain the inhibitory activity. In addition, the hydroxyethylaminomethyl group was suitable for the IL-5 inhibitory activity. Moreover, the hydrophobic substituents on carbon played an important role in the IL-5 inhibitory activity of these analogs. However, N-substituted analogs did not improve inhibitory activity. In addition, MTT assay of compounds I [n = 1; R = Et, cyclohexylmethyl; R¹ = H] with normal B lymphoblasts revealed that they had no significant effects on cell viability.

Haraguchi, Kazutoshi published the artcileNew Aqueous Solutions with Lower Viscosities than Water, Recommanded Product: 3,3,3-Trifluoropropan-1-ol, the publication is Bulletin of the Chemical Society of Japan (2021), 94(4), 1185-1191, database is CAplus.

Liquid water exhibits many anomalous phys. properties because of its unique structure and hydrogen bonding networks, which were mostly uncovered at the beginning of the 20th century. Because of its interesting properties and microstructures under various conditions and in aqueous solutions, understanding the behavior of water is important, but remains scientifically challenging. Regarding the viscosity of aqueous solutions, despite the discovery 147 years ago that very small amounts of certain salts decrease the viscosity of water slightly, there has been no significant progress to date. Herein, we report new aqueous solutions, with low additive fractions and much lower viscosities than pure water, which exhibit unique viscosity-composition curves. The findings should spark renewed interest in scientific research on water, which may greatly impact numerous industries.

Grabosch, Carsten published the artcileA dual Click’ strategy for the fabrication of bioselective, glycosylated self-assembled monolayers as glycocalyx models, Quality Control of 96345-79-8, the publication is Organic & Biomolecular Chemistry (2013), 11(24), 4006-4015, database is CAplus and MEDLINE.

Solid surfaces decorated with specific saccharide patterns can serve as a model for the chem. and structurally highly complex glycocalyx of eukaryotic cells. Here we present an approach based on self-assembled monolayers on gold, which are built up in a three-step manner to provide a solid basis, a biorepulsive oligoethylene glycol part, and a specific glycoside terminus, e.g. I, in a modular way. Of the different reaction sequences, the one with two consecutive click reactions’ (the copper(I)-catalyzed 1,3-dipolar cycloaddition of alkynes with azides and the thiourea-bridging of isothiocyanates with amines) directly on SAM’ results in the densest layers, as demonstrated by IR absorption reflection spectroscopy and ellipsometry. As a real life’ test, the surfaces obtained this way were used for bacterial adhesion experiments Here the biorepulsivity of the middle part of the SAMs as well as specific binding to the carbohydrate termini could be clearly demonstrated.

Taniguchi, Ikuo published the artcilePiperazine-immobilized polymeric membranes for CO₂ capture: mechanism of preferential CO₂ permeation, HPLC of Formula: 622-40-2, the publication is Polymer Journal (Tokyo, Japan) (2021), 53(1), 129-136, database is CAplus.

Amines are incorporated into various membranes to improve their CO₂ separation performance. With amine-containing polymeric membranes, gas transport properties are often enhanced under humidity, where CO₂ migrates through the membranes in the form of bicarbonate ions. Piperazine (Pz) and its derivatives are known to catalyze the conversion of CO₂ to bicarbonate ions and have been used in liquid amine scrubbing technol. Piperazines were immobilized in poly(vinyl alc.) (PVA), and the resulting polymeric membranes showed high CO₂ separation performance over H₂ and CH₄. The gas transport properties were dependent on the chem. structure of the amines. In particular, 3-(1-piperazinyl)-1,2-propanediol (PzPD)-containing polymeric membranes gave excellent CO₂ separation performance, and the CO₂ permeability and CO₂ selectivity over CH₄ were 1060 Barrer and 370, resp., at 50°C and 90% relative humidity with a transmembrane CO₂ pressure of 11 kPa. The interaction between PzPD and CO₂ was quant. studied by inverse-gate decoupling ¹³C NMR spectroscopy. CO₂ interacted with the secondary amino group on the Pz ring to form a carbamate, which was readily hydrolyzed to produce bicarbonate ions. The hydroxyl group on the C2 carbon of PzPD facilitated the interaction between CO₂ and the amine through hydrogen bonding, resulting in enhanced diffusivity of CO₂ in the membranes.

Wada, Masanori published the artcileReactions of 1,8-Dimethoxy-9-phenylxanthen-9-ol in the Presence of an Acid, and Its Basicity, SDS of cas: 596-38-3, the publication is Bulletin of the Chemical Society of Japan (1999), 72(4), 779-785, database is CAplus.

In the presence of a catalytic amount of acid, the title xanthenol (1) reacted in acetone to give 1,8-dimethoxy-9-phenylxanthen-9-ylmethyl Me ketone. Analogous reactions were observed for Et Me ketone and acetophenone, but not for di-Et ketone. Propanal and butanal also reacted to give 2-(1,8-dimethoxy-9-phenylxanthen-9-yl)propanal and 2-(1,8-dimethoxy-9-phenylxanthen-9-yl)butanal, resp. In hot primary and secondary alcs.,1 was reduced to give 1,8-dimethoxy-9-phenylxanthene. 1 also reacted with methoxybenzenes, phenol, and N-alkylanilines to give 9-aryl-1,8-dimethoxy-9-phenylxanthenes. The basicity of 1, or the stability of the carbenium ion (pK_R⁺ = -0.81), was measured in hydrochloric acid and compared with those of related 9-arylxanthen-9-ols, such as 1,8-dimethoxy-9-(2,6-dimethoxyphenyl)xanthen-9-ol (1.14), 9-(2,6-dimethoxyphenyl)xanthen-9-ol (4.80) (8), and 9-phenylxanthen-9-ol (0.75). The drastic differences in the reactivities and the basicity between 1 and 8 were attributed to a steric effect rather than an electronic effect.
