Well-defined 3-miktoarm star copolymer 3μ-HBPE(PCL)₂ (HBPE: hyperbranched polyethylene, PCL: poly[ε-caprolactone]) was synthesized by combining chain walking polymerization (CWP), ring-opening polymerization (ROP), and “click” chem. The synthetic methodol. includes the following steps: (a) synthesis of in-chain ethynyl-functionalized PCL, (PCL)₂-C CH by ROP of ε-caprolactone (CL) with ethylene-functionalized solketal (3-[prop-2-yn-1-yloxy] propane-1,2-diol) as difunctional initiator and phosphazene superbase t-BuP₂ as catalyst; (b) synthesis of azido-functionalized hyperbranched PE (HBPE-N₃) by CWP of ethylene with α-diimine-Pd(II) catalyst, followed by quenching with excess 4-vinylbenzyl chloride and transformation of chloro to azide group with sodium azide; and (c) “clicking” HBPE-N₃ and (PCL)₂-C CH using copper(I)-catalyzed azide-alkyne cycloaddition ¹H NMR spectroscopy, gel permeation chromatog., Fourier-transform IR spectroscopy, and differential scanning calorimetry were used to determine the mol. characteristics and thermal properties of the polymers. Self-assembly behavior of 3μ-HBPE (PCL)₂ in petroleum ether, a selective solvent for HBPE, was investigated by dynamic light scattering, at. force microscopy, and transmission electron microscopy.

Hafnium-doped silica nanotubes for the upgrading of glycerol into solketal: Enhanced performances and in-depth structure-activity correlation was written by Soumoy, Loraine;Celis, Chloe;Debecker, Damien P.;Armandi, Marco;Fiorilli, Sonia;Aprile, Carmela. And the article was included in Journal of Catalysis in 2022.Name: (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol This article mentions the following:

An unprecedented type of Hf-doped silica nanotubes was synthesized using a straightforward one-pot sol-gel procedure. The well-defined nanotubes with a diameter of 14-20 nm exhibited high sp. surface area and a widely open texture. The method – involving a key pH adjustment step – allowed a quant. insertion of hafnium in the materials (Si/Hf = 74) and favored the insertion of Hf as dispersed species. Depending on the synthesis parameters, the chem. environment around Hf was modified, as evidenced by XPS, NH₃-TPD and NH₃-IR. Hf-doped silica nanotubes showed excellent activity in the conversion of glycerol to solketal, a reaction of high relevance in the context of biorefineries. Importantly, the turnover frequency and the acidity were unambiguously correlated with the insertion of Hf in the silica matrix. The best catalyst was proven to be stable and recyclable, and this sustainable reaction was also amenable to further catalytic enhancement upon optimized reaction conditions. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Name: (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol).

Al-free Zr-beta zeolite as a selective catalyst for the ketalization of glycerol was written by Vannucci, Julian A.;Legnoverde, Maria S.;Dalla Costa, Bruno O.;Basaldella, Elena I.;Nichio, Nora N.;Pompeo, Francisco. And the article was included in Molecular Catalysis in 2022.Application of 100-79-8 This article mentions the following:

Two Zr-beta zeolites were synthesized using different methods. Method 1 consisted in the formation of a dealuminated zeolite beta seed followed by Zr incorporation and thermal treatment (ZBZr₁). In Method 2, zeolite beta was prepared and then, the dealumination and subsequent Zr incorporation were performed (ZBZr₂). These materials were tested in the ketalization of glycerol with acetone and compared with a SBAsulf. Both preparation methods incorporate Zr in the zeolitic framework, and no ZrO₂ is detected. Method 1 developed crystallites with an average size of 260 nm, Si/Zr ratio ∼100, total amount of acid sites of 0.375 mmol.g^-1 and a ratio of Bronsted to Lewis acid sites of 1.9. In the case of Method 2, values of 1500 nm, ∼86, 0.32 mmol.g^-1 and 0.7 were obtained, resp. The ZBZr₂ sample presented low catalytic activity, possibly due to diffusion limitations. The turnover frequency (TOF) was calculated as 44.84 and 60.37 min^-1 for ZBZr₁ and SBA_sulf , resp. After one cycle of reaction, both ZBZr₁ and SBA_sulf showed a decrease in the glycerol conversion, however, the selectivity remained constant in the ZBZr₁ material after the reaction cycle and the catalytic activity could be reestablished after a thermal treatment. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Application of 100-79-8).

A continuous-flow process for the acetalization of crude glycerol with acetone on zeolite catalysts was written by Kowalska-Kus, J.;Held, A.;Nowinska, K.. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020.Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol This article mentions the following:

A continuous flow process using heterogeneous catalysts like zeolites (BEA, MFI, FAU) was developed for the conversion of crude glycerol with acetone to solketal (2,2-dimethyl-1,3-dioxolane-4-methanol). It was found that BEA zeolite and the hierarchical zeolite of MFI structure exhibit a high catalytic activity in solketal production for 3 h on stream. Almost 85% of glycerol conversion and 98% selectivity to solketal was achieved after 1 h of the reaction. The regeneration of spent catalysts by means of calcination with following ionic exchange restored the initial activity of the applied samples. The effect of particular impurities (alk. cations, water, and MONG (matter organic non glycerol)) present in crude glycerol, on the deactivation process of catalysts, was also explored. Anal. of carbon balance and low-temperature nitrogen adsorption/desorption measurements, as well as FT-IR spectra of applied materials (pure and crude glycerol and spent catalysts) evidenced that the concurrent presence of MONG and alk. cations reduce the zeolite catalysts activity. Considering the alteration of selectivity toward five and six membered isomers with declining acidity of spent catalyst, some tentative reaction paths of both isomers formation have been proposed. In the experiment, the researchers used many compounds, for example, (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol (cas: 100-79-8Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol).

The effect of grafting density and side chain length on the conformation of PEG grafted bottlebrush polymers was written by Xiao, Lifen;Li, Jie;Peng, Gang;Huang, Geng. And the article was included in Reactive & Functional Polymers in 2020.Quality Control of (2,2-Dimethyl-1,3-dioxolan-4-yl)methanol This article mentions the following:

PEG grafted polymers are a kind of promising materials, and widely applied in polymer electrolytes, lubricants, biotechnol. and biomedical science. While up to now, systematical researches of the relationship between architecture and conformation of PEG grafted polymers are very rare. Here, we efficiently and successfully prepared a series of PEG grafted polymers with different grafting d., and side chain length by combining ring-opening metathesis polymerization (ROMP) and Copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, and then characterized the conformations of the synthesized bottlebrush polymers by AFM technique. The AFM images showed that all the polymers P(NB-alkyne)₄₀₀-g-PEG with low grafting d. were spherical morphol., while the polymers P(NB-2alkyne)₄₀₀-g-PEG and P(NB-4alkyne)₃₉₄-g-PEG presented cylindrical morphol., which indicated that only grafting d. could determine the shape of the prepared PNB-g-PEG bottlebrush polymers. While, the side chain length could affect the size of prepared PEG grafted bottlebrush polymers.

Discovery of indoximod prodrugs and characterization of clinical candidate NLG802 was written by Kumar, Sanjeev;Jaipuri, Firoz A.;Waldo, Jesse P.;Potturi, Hima;Marcinowicz, Agnieszka;Adams, James;Van Allen, Clarissa;Zhuang, Hong;Vahanian, Nicholas;Link, Charles Jr.;Brincks, Erik L.;Mautino, Mario R.. And the article was included in European Journal of Medicinal Chemistry in 2020.Synthetic Route of C6H12O3 This article mentions the following:

A series of different prodrugs of indoximod, including esters and peptide amides were synthesized with the aim of improving its oral bioavailability in humans. The pharmacokinetics of prodrugs that were stable in buffers, plasma and simulated gastric and intestinal fluids was first assessed in rats after oral dosing in solution or in capsule formulation. Two prodrugs that produced the highest exposure to indoximod in rats were further tested in Cynomolgus monkeys, a species in which indoximod has oral bioavailability of 6-10% and an equivalent dose-dependent exposure profile as humans. NLG802 was selected as the clin. development candidate after increasing oral bioavailability (>5-fold), C_max (6.1-3.6 fold) and AUC (2.9-5.2 fold) in monkeys, compared to equivalent molar oral doses of indoximod. NLG802 is extensively absorbed and rapidly metabolized to indoximod in all species tested and shows a safe toxicol. profile at the anticipated therapeutic doses. NLG802 markedly enhanced the anti-tumor responses of tumor-specific pmel-1 T cells in a melanoma tumor model. In conclusion, NLG802 is a prodrug of indoximod expected to increase clin. drug exposure to indoximod above the current achievable levels, thus increasing the possibility of therapeutic effects in a larger fraction of the target patient population.

In the framework of the present study, a triumphant attempt was made to obtain biocompatible ZnOES NPs using E. sonchifolia (L.) plant extracts A repercussion of solvent alteration on the biol. and photocatalytic properties of ZnOES NPs has also been delineated employing two solvents viz. water and ethanol during the extraction of plant material. The formation of ZnOES NPs was confirmed through FTIR, PXRD, and UV-visible spectroscopy, which was further upheld by the elemental mapping study. Addnl., the NPs were examined through Rietveld refinement of P-XRD data obtained, FE-SEM, and BET analyses. The results of these analyses have substantiated the formation of mesoporous ZnOES NPs with divergent shapes and sizes ranging between 18.12 and 25.70 nm. The in-vitro antidiabetic activity of ZnOES NPs carried out revealed their excellent α-amylase inhibition activity (85.53 ± 0.002%). Furthermore, the in-vitro anti-inflammatory activity unfolded their biocompatibility by exhibiting a % HRBCMS up to 89.31 ± 0.002%. The NPs also displayed anti-microbial activities against Staphylococcus aureus, Bacillus subtulis, Pseudomonas aeroginosa, Pseudomonas syringae, and Escherichia coli. Therewithal the photo-degradation experiments of ZnOES nanocatalysts manifested superlative dye degradation efficacies exhibiting a % degradation of 92.01 and 79.36 for Methylene Blue and Methyl orange dyes resp. Thus the studies have evinced the antidiabetic, antimicrobial, and dye degradation potentialities of biocompatible ZnOES NPs with excellent stability and reusability.
