Tsagdi, A. published the artcileBlend membranes based on N1-alkyl-substituted imidazolium functionalized polymers and aromatic polyethers: influence of N1-alkyl substituent on properties and alkaline stability, Synthetic Route of 111-83-1, the publication is Polymer Bulletin (Heidelberg, Germany) (2022), 79(3), 1647-1668, database is CAplus.

N1-alkyl (octyl and dodecyl)-substituted imidazolium-based PVBC homopolymers have been synthesized via N-quaternization reaction of N1-alkyl imidazole and PVBC precursor homopolymer bearing reactive benzyl chloride moieties. Due to their poor film forming properties and water solubility, these homopolymers were blended with aromatic polyethers bearing main chain pyridine units at different compositions in order to study the effect of alkyl chain length on morphol., water uptake, swelling ability and chem. stability of the prepared membranes. The B2 blend membrane with the highest N1-dodecyl-substituted imidazolium PVBC content (65 wt%) exhibited the highest water uptake (54%) despite its lower IEC value compared to the corresponding one containing N1-octyl-substituted imidazolium PVBC, low swelling ratio and a phase separated morphol. Evaluation of the chem. stability in 3.6 M KOH solution at 80°C for 7 days revealed the degradation of imidazolium via ring opening, as evidenced by ATR-FT-IR spectroscopy. Therefore, new blends having as second constituent, the N1-alkyl-substituted imidazolium functionalized poly(PVBC-co-AA₂₀) copolymers containing acrylic acid units were fabricated targeting to the improvement of chem. stability via ionic cross linking. The prepared D1 and D2 blend membranes containing 60 and 65 wt% dodecyl-imidazolium functionalized poly(PVBC-co-AA₂₀) copolymer content, resp., were flexible, exhibited moderate IECs (1.47-1.60 meq/g) and sufficient water uptakes (up to 30%). D2 blend membrane showed excellent chem. stability after testing in 3.6 M KOH solution at 80°C for 30 days, as confirmed by ATR-FT-IR spectroscopy and TGA anal. The excellent chem. stability can probably be attributed to the steric hindrance effect of N1 dodecyl substituent which effectively protects the C2 position of imidazolium from hydroxide attack as well as to the formation of a dense, ionic crosslinked structure that hinders hydroxide penetration.

Copper-Catalyzed Asymmetric Coupling of Allenyl Radicals with Terminal Alkynes to Access Tetrasubstituted Allenes

In contrast to the wealth of asymmetric transformations for generating central chirality from alkyl radicals, the enantiocontrol over the allenyl radicals for forging axial chirality represents an uncharted domain. The challenge arises from the unique elongated linear configuration of the allenyl radicals that necessitates the stereo-differentiation of remote motifs away from the radical reaction site. We herein describe a copper-catalyzed asymmetric radical 1,4-carboalkynylation of 1,3-enynes via the coupling of allenyl radicals with terminal alkynes, providing diverse synthetically challenging tetrasubstituted chiral allenes. A chiral N,N,P-ligand is crucial for both the reaction initiation and the enantiocontrol over the highly reactive allenyl radicals. The reaction features a broad substrate scope, covering a variety of (hetero)aryl and alkyl alkynes and 1,3-enynes as well as radical precursors with excellent functional group tolerance.

Anticancer Impacts ofTerminalia catappaExtract on SW480 Colorectal Neoplasm Cell Line

Purpose Colorectal cancer (CRC) is one of the most lethal and prevalent cancers throughout the world. Despite the remarkable advance in the field, drug resistance still remains as an unresolved problem in cancer. Hence, finding effective compounds with minimal side effects to fight cancer is of central priority. Herbal products have been traditionally used to prevent and treat a variety of diseases. Methods In the present study, the antitumor effect ofTerminalia catappaplant ethanolic extract (TCE) was assessed on SW480 CRC model cell line. In this regard, effects of TCE were evaluated on the proliferation, apoptosis, and migration of SW480 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, Annexin V/PI flow cytometry, and scratch tests, respectively. Furthermore, changes in the expression of genes involved in these events including Bax, Bcl-2, Caspase 3, Caspase 8, Caspase 9, MMP-13, miR-21, and miR-34a were measured by quantitative real-time PCR (qRT-PCR). Results According to the MTT results, TCE reduced the proliferation of SW480 cells significantly. The flow cytometry test also revealed a notable rate of apoptosis induction after TCE treatment. An inhibitory effect on cell migration was also evident in scratch test. Expression patterns of the assessed genes also changed subsequent to TCE treatment. Conclusion The results of this study indicated thatT. catappacould be considered as a potential source of anticancer compounds and a candidate for further investigations.

Carboxyboronate as a Versatile In Situ CO Surrogate in Palladium-Catalyzed Carbonylative Transformations

The application of carboxy-MIDA-boronate (MIDA=N-methyliminodiacetic acid) as an in situ CO surrogate for various palladium-catalyzed transformations is described. Carboxy-MIDA-boronate was previously shown to be a bench-stable boron-containing building block for the synthesis of borylated heterocycles. The present study demonstrates that, in addition to its utility as a precursor to heterocycle synthesis, carboxy-MIDA-boronate is an excellent in situ CO surrogate that is tolerant of reactive functionalities such as amines, alcohols, and carbon-based nucleophiles. Its wide functional-group compatibility is highlighted in the palladium-catalyzed aminocarbonylation, alkoxycarbonylation, carbonylative Sonogashira coupling, and carbonylative Suzuki-Miyaura coupling of aryl halides. A variety of amides, esters, (hetero)aromatic ynones, and bis(hetero)aryl ketones were synthesized in good-to-excellent yields in a one-pot fashion.

Differential effect of surfactants tetra-n-butyl ammonium bromide and N-Cetyl-N, N, N-trimethyl ammonium bromide bound to nano-cellulose on binding and sustained release of some non-steroidal anti-inflammatory drugs

Nano crystalline cellulose (NCC) modified with cationic surfactant CTAB (N-Cetyl-N, N, N-trimethyl ammonium bromide) proved as effective drug delivery excipient for sustained release of non-steroidal anti-inflammatory drugs (NSAIDs). In the present work, our purpose was to study the effect of another cationic surfactant TBAB (tetra-n-butyl ammonium bromide) used to modify NCC on binding and sustained release of hydrophobic NSAIDs. NCC modified TBAB was characterized by FTIR & TGA analysis. TBAB-NSAID interactions have been assessed using CHEM3D. The sustained release character was monitored by time dependent serum protein protecting and time dependent anti-cathepsins activities. The NCC-TBAB exhibited the binding efficiency for NSAIDs in the range of 42-25% depending upon the hydrophobicity of NSAID and released the drug up to 60 min. The research problem added to the existing knowledge of suitable surfactants required to change the hydrophilic nature of NCC to act as carrier for hydrophobic drugs. TBAB surfactant having shorter alkyl chain length exhibited lower binding efficiency and decreased sustain release of drugs as compared to CTAB having longer alkyl chain length.

Visible light-driven flower-like Bi/BiOClxBr(1-x) heterojunction with excellent photocatalytic performance

In this work, a series of flower-like Bi/BiOClxBr(1-x) heterojunction photocatalysts have been developed. Bi nanoparticles were grown on the BiOClxBr(1-x) nanosheets via an in situ chemical reduction with the assistance of cetyltrimethylammonium chloride and cetyltrimethylammonium bromide aqueous solution. The in situ growth of Bi nanoparticles on the BiOClxBr(1-x) nanosheets could not only give rise to the optical absorption in the visible region, but also promote the photocatalytic performance of BiOClxBr(1-x). Bi/BiOCl0.8Br0.2 exhibited the highest photocatalytic performance, which could completely degrade RhB in 12 min under the UV light irradiation and 6 min under visible light irradiation, respectively. Moreover, holes and superoxide radicals were verified to be the primarily active species in the photocatalytic process.

A simple hypochlorous acid signaling probe based on resorufin carbonodithioate and its biological application

A novel hypochlorous-acid-selective signaling probe based on the carbonodithioate derivative of resorufin (RT-1) was developed. Probe RT-1 showed prominent colorimetric and turn-on type fluorescence signaling behavior exclusively toward hypochlorous acid, induced by oxidative hydrolysis, to regenerate resorufin dye. Hypochlorous acid signaling was not affected by the presence of common metal ions and anions as background, except for the redox active bromide and iodide anions. The detection limit of RT-1 for hypochlorous acid was found to be 2.18 x 10(-9) M (0.11 ppb), and the signaling was completed within 3 min. It was also confirmed that hypochlorous acid signaling by the carbonodithioate-based probe RT-1 was superior to that of the closely related carbonothioate derivative RT-2. This was rationalized by density functional theory calculations, which demonstrated that the CS sulfur atom of the former is more negatively charged than that of the latter. Finally, as a biological application of the probe, visualization of hypochlorous acid in RAW 264.7 murine macrophages and HeLa cells was successfully conducted to detect the cellular response to hypochlorous acid.
