Compound: 1-(4-(4-Hydroxyphenyl)piperazin-1-yl)ethanone, is researched, Molecular C12H16N2O2, CAS is 67914-60-7, about Stereoisomers of ketoconazole: preparation and biological activity. Author is Rotstein, David M.; Kertesz, Denis J.; Walker, Keith A. M.; Swinney, David C..

The four stereoisomers of the antifungal agent ketoconazole, (2S,4R)-, (2R,4R)-, (2R,4S)-, and (2S,4S)-(imidazolylmethyl)phenyl{[(acetylpiperazinyl)phenoxy]methyl}dioxolanes I, were prepared and evaluated for their selectivity in inhibiting a number of cytochrome P 450 enzymes. Thus, (bromomethyl)phenyldioxolanes II condensed with 4-(N-acetylpiperazino)phenol and imidazole to give I. II were prepared by bromination of 2′,4′-dichloroacetophenone followed by reaction with (S)- and (R)-solketal tosylate. Large differences in selectivity among the isomers were observed for inhibition of the cytochromes P 450 involved in steroid biosynthesis, whereas little difference was observed for inhibition of those associated with hepatic drug metabolism The cis-(2S,4R) and trans-(2R,4R) isomers are equipotent in inhibiting corticoid 11β-hydroxylase and much more effective than their antipodes. Little selectivity was observed for inhibition of cholesterol side chain cleavage or xenobiotic hydroxylases. These data indicate that the affinity of azoles for cytochrome P 450 enzymes involved in steroid synthesis is high dependent on the stereochem. of the entire mol., whereas binding to drug metabolizing enzymes is a less selective process.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Folic acid-terminated poly(2-diethyl amino ethyl methacrylate) brush-gated magnetic mesoporous nanoparticles as a smart drug delivery system, published in 2021, which mentions a compound: 7789-45-9, Name is Cupric bromide, Molecular Br2Cu, Computed Properties of Br2Cu.

Currently, chemotherapy is an important method for the treatment of various cancers. Nevertheless, it has many limitations, such as poor tumor selectivity and multi-drug resistance. It is necessary to improve this treatment method by incorporating a targeted drug delivery system aimed to reduce side effects and drug resistance. The present work aims to develop pH-sensitive nanocarriers containing magnetic mesoporous silica nanoparticles (MMSNs) coated with pH-responsive polymers for tumor-targeted drug delivery via the folate receptor. 2-Diethyl amino Et methacrylate (DEAEMA) was successfully grafted on MMSNs via surface initiated ARGET atom transfer radical polymerization (ATRP), with an average particle size of 180 nm. The end groups of poly (2-(diethylamino)ethyl methacrylate) (PDEAEMA) brushes were converted to amines, followed by a covalent bond with folic acid (FA) as a targeting agent. FA conjugated to the nanoparticle surface was confirmed by XPS. pH-Responsive behavior of PDEAEMA brushes was investigated by Dynamic Light Scattering (DLS). The nanoparticles average diameters ranged from ca. 350 nm in basic media to ca. 650 in acidic solution Multifunctional pH-sensitive magnetic mesoporous nanoparticles were loaded with an anti-cancer drug (Doxorubicin) to investigate their capacity and long-circulation time. In a cumulative release pattern, doxorubicin (DOX) release from nano-systems was ca. 20% when the particle exposed to acidic media, compared to ca. 5% in basic media. The nano-systems have excellent biocompatibility and are minimally toxic when exposed to MCF-7, and -MCF-7 ADR cells.

Category: oxazolidine. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: Cupric bromide, is researched, Molecular Br2Cu, CAS is 7789-45-9, about Conjugated Cross-linked Phenothiazines as Green or Red Light Heterogeneous Photocatalysts for Copper-Catalyzed Atom Transfer Radical Polymerization. Author is Dadashi-Silab, Sajjad; Lorandi, Francesca; DiTucci, Matthew J.; Sun, Mingkang; Szczepaniak, Grzegorz; Liu, Tong; Matyjaszewski, Krzysztof.

Using the power of light to drive controlled radical polymerizations has provided significant advances in synthesis of well-defined polymers. Photoinduced atom transfer radical polymerization (ATRP) systems often employ UV light to regenerate copper activator species to mediate the polymerization Taking full advantage of long-wavelength visible light for ATRP would require developing appropriate photocatalytic systems that engage in photoinduced electron transfer processes with the ATRP components to generate activating species. Herein, we developed conjugated microporous polymers (CMP) as heterogeneous photocatalysts to exploit the power of visible light in promoting copper-catalyzed ATRP. The photocatalyst was designed by crosslinking phenothiazine (PTZ) as a photoactive core in the presence of dimethoxybenzene as a crosslinker via the Friedel-Crafts reaction. The resulting PTZ-CMP network showed photoactivity in the visible region due to the extended conjugation throughout the network because of the aromatic groups connecting the PTZ units. Therefore, photoinduced copper-catalyzed ATRP was performed with CMPs that regenerated activator species under green or red light irradiation to start the ATRP process. This resulted in efficient polymerization of acrylate and methacrylate monomers with high conversion and well-controlled mol. weight The heterogeneous nature of the photocatalyst enabled easy separation and efficient reusability in subsequent polymerizations

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Cupric bromide(SMILESS: [Cu+2].[Br-].[Br-],cas:7789-45-9) is researched.Formula: C14H11N3O2. The article 《Improving Hemocompatibility: How Can Smart Surfaces Direct Blood To Fight against Thrombi》 in relation to this compound, is published in ACS Applied Materials & Interfaces. Let’s take a look at the latest research on this compound (cas:7789-45-9).

Nature utilizes endothelium as a blood interface that perfectly controls hemostasis, preventing the uncontrolled formation of thrombi. The management of pos. and neg. feedback that finely tunes thrombosis and fibrinolysis is essential for human life, especially for patients who undergo extracorporeal circulation (ECC) after a severe respiratory or cardiac failure. The exposure of blood to a surface different from healthy endothelium inevitably initiates coagulation, drastically increasing the mortality rate by thromboembolic complications. In the present study, an ultrathin antifouling fibrinolytic coating capable of disintegrating thrombi in a self-regulated manner is reported. The coating system is composed of a polymer brush layer that can prevent any unspecific interaction with blood. The brushes are functionalized with a tissue plasminogen activator (tPA) to establish localized fibrinolysis that solely and exclusively is active when it is required. This interactive switching between the dormant and active state is realized through an amplification mechanism that increases (pos. feedback) or restores (neg. feedback) the activity of tPA depending on whether a thrombus is detected and captured or not. Thus, only a low surface d. of tPA is necessary to lyse real thrombi. Our work demonstrates the first report of a coating that self-regulates its fibrinolytic activity depending on the conditions of blood.

Compound: Cupric bromide, is researched, Molecular Br2Cu, CAS is 7789-45-9, about Imine-based covalent organic framework as photocatalyst for visible-light-induced atom transfer radical polymerization.

Photoinduced atom transfer radical polymerization (ATRP) is an economical and environment-friendly method for synthesizing polymers with pre-designable structures and precise mol. weight Although significant progress for copper-mediated photoinduced ATRP has been achieved, several drawbacks still remain, such as poor electron transfer capability and absorption bands of photocatalysts near UV region.

Silver nanowires (AgNWs) have attracted growing interest because of their wide range of applications in modern nano electronic appliances. During polyol method, the presence of cations and anions in the reaction solution has influence on the final morphol. of AgNWs. Here we report a feasible way to prepare AgNWs by polyol method. Copper bromide (CuBr2) salt was used to provide anions and cations in the reaction solution The anions (Br-) helps in reducing the amount of free Ag+ by forming silver bromide (AgBr) during initial silver seeds formation and the cations scavenge oxygen from the surface of AgNWs during preferential growth of the AgNWs. Ethylene glycol (EG) was used as a solvent and reducing agent, silver nitrate (AgNO3) was used as Ag source and polyvinyl pyrrolidone (PVP) was used as a capping agent. The effects of various factors which influence the final morphol. of AgNWs were studied. AgNWs were successfully synthesized in the presence of CuBr2 salt. The morphol. of the synthesized AgNWs was characterized by the SEM and TEM. The crystallinity was characterized by HRTEM, SAED and XRD. The LSPR peaks of Ag nanostructures were revealed by UV-Vis spectroscopy. The conductive properties of AgNWs thin conductive films were studied by coating the synthesized nanowires on polyethylene terephthalate (PET) substrate.

Keywords: polymethyl acrylate preparation ATRP initiator polymer dispersity kinetics.They researched the compound: Cupric bromide( cas:7789-45-9 ).Application In Synthesis of Cupric bromide. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:7789-45-9) here.

Herein we present a simple batch method to control polymer dispersity using a mixture of two ATRP initiators with different reactivities. A wide dispersity spectrum (D ∼ 1.1-1.7) is achieved by altering the ratio between the two ATRP initiators while sustaining fairly monomodal mol. weight distributions. Depending on the targeted dispersity, a distinct kinetic profile was observed and, in contrast to previous ATRP approaches, near-quant. conversions were obtained even for the highest dispersities. High end-group fidelity was also maintained in all cases as exemplified by chain extensions. Significantly, this method can be applied to various ATRP protocols as well as to various monomer classes.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Cupric bromide, is researched, Molecular Br2Cu, CAS is 7789-45-9, about Fastening Br- Ions at Copper-Molecule Interface Enables Highly Efficient Electroreduction of CO2 to Ethanol, the main research direction is copper bromide dodecanethiol carbon dioxide electroreduction catalyst.Recommanded Product: Cupric bromide.

Developing advanced electrocatalysts to convert CO2 into liquid fuels such as ethanol is critical for utilizing intermittent renewable energy. The formation of ethanol, however, is generally less favored compared with the other hydrocarbon products from Cu-based electrocatalysts. Herein, we construct an efficient electrocatalyst for ethanol formation based on dodecanethiol-modified CuBr, which in situ generates a robust Br-doped Cu-thiol interface. The obtained electrocatalyst shows a significantly enhanced C2+ Faradaic efficiency of 72%, among which the Faradaic efficiency of ethanol is 35.9%. Notably, the ratio of ethanol to ethylene significantly increases from 0.32 for pristine CuBr to 1.08 for dodecanethiol-modified CuBr. The improved electrocatalytic activity is related to the modulated adsorption energy of key intermediates on the Br-doped Cu-thiol interface as verified by d. functional theory (DFT) calculations The present study highlights the great potential of utilizing hybrid metal-mol. interfaces for improving electrocatalytic CO2 conversion.

Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Membrane Science called Thin-film composite membranes based on hyperbranched poly(ethylene oxide) for CO2/N2 separation, Author is Zhang, Gengyi; Tran, Thien N.; Huang, Liang; Deng, Erda; Blevins, Adrienne; Guo, Wenji; Ding, Yifu; Lin, Haiqing, which mentions a compound: 7789-45-9, SMILESS is [Cu+2].[Br-].[Br-], Molecular Br2Cu, Application In Synthesis of Cupric bromide.

Crosslinked amorphous poly(ethylene oxide) (XLPEO) is one of the leading membrane materials for post-combustion CO2 capture. For example, XLPEO prepared from poly(ethylene glycol) Me ether acrylate (PEGMEA) exhibited CO2 permeability of 570 Barrer and CO2/N2 selectivity of 41 at 35°C. However, these XLPEOs cannot be dissolved in coating solutions, making it impossible to be fabricated into thin-film composite (TFC) membranes using state-of-the-art manufacturing processes. In this study, we synthesized high mol. weight yet soluble HPEO via atom transfer radical polymerization (ATRP). These polymers were thoroughly characterized and compared with XLPEO, including thermal transitions, free volumes, and pure-gas sorption and permeation properties. A polymer with the best combination of CO2 permeability (540 Barrer) and CO2/N2 selectivity (43) was fabricated into defect-free TFC membranes with a thickness as thin as 506 ± 44 nm. When challenged with simulated flue gas containing water vapor at 35°C for over 100 h, the membrane shows stable CO2 permeance of 850 GPU and CO2/N2 selectivity of 37, comparable to the leading com. membranes for carbon capture.
