Priya, V.; Subalakshmi, M. published the artcile< Study of oxidation of dyes by N-chlorosuccinimide in aqueous acetic acid medium: A kinetic and mechanistic>, SDS of cas: 128-09-6, the main research area is dye chlorosuccinimide acetic acid medium oxidation kinetic.

Kinetics of oxidation of Dyes by N-Chlorosuccinamide(NCS) in acetic acid medium has been done in the presence of hydrochloric acid. The reaction follows first order kinetics with respect to both [NCS], [Substrate] and [HCl]. Increases in ionic strength increases the rate and addition of the reaction product succinamide has a slight retarding effect on the reaction rate. Increase in the dielec. constant of the medium decreases the rate. Activation parameters have been evaluated from Arrhenius plot by studying the reaction at different temperature [40-55 oC] and oxidation products are identified. A most probable reaction mechanism is proposed and an appropriate rate law is deduced to account for the observed kinetic data.

Yasunaga, Katsuaki; Kiyonari, Akiko; Nakagawa, Munehiro; Yoshikawa, Kunie published the artcile< Investigation into the ability of the Salmonella umu test to detect DNA damage using antitumor drugs>, Safety of 2-(Bis(2-chloroethyl)amino)-1,3,2-oxazaphosphinane 2-oxide hydrate, the main research area is antitumor genotoxicity Salmonella umu gene.

In order to examine the ability of the umu test detecting system, 18 antitumor drugs were tested using the Salmonella umu test. The tested antitumor drugs were selected so as to produce different biochem. actions, and they were classified into three categories; five agents of group I (antimetabolites), eight agents of group II (alkylating agents), and five agents of group III (antibiotics). The results showed that all antimetabolites, all alkylating agents, and three of the antibiotics had pos. responses, but the antibiotics aclarubicin (ACR) and chromomycin A3 (CHR) had neg. responses. Both antibiotics that gave neg. responses were anthracyclines, but daunomycin (DNR), which was one of the anthracyclines, had a pos. result in the umu test. These results suggest that it is possible for the umu test to detect genotoxicity of chems. regardless of the types of DNA damage (inhibition of DNA synthesis relative enzyme, DNA base alkylating, DNA strand-break, and DNA adduct), but difficult for it to detect genotoxicity of any anthracyclines.

Lee, Hiu-Fung; Lacbay, Cyrus M.; Boutin, Rebecca; Matralis, Alexios N.; Park, Jaeok; Waller, Daniel D.; Guan, Tian Lai; Sebag, Michael; Tsantrizos, Youla S. published the artcile< Synthesis and Evaluation of Structurally Diverse C-2-Substituted Thienopyrimidine-Based Inhibitors of the Human Geranylgeranyl Pyrophosphate Synthase>, Name: 3-Chloro-4-methylbenzene-1-sulfonyl chloride, the main research area is multiple myeloma antimyeloma liver toxicity thienopyrimidine hGGPPS inhibitor pharmacokinetics.

Novel analogs of C-2-substituted thienopyrimidine-based bisphosphonates (C2-ThP-BPs) are described that are potent inhibitors of the human geranylgeranyl pyrophosphate synthase (hGGPPS). Members of this class of compounds induce target-selective apoptosis of multiple myeloma (MM) cells and exhibit antimyeloma activity in vivo. A key structural element of these inhibitors is a linker moiety that connects their (((2-phenylthieno[2,3-d]pyrimidin-4-yl)amino)methylene)bisphosphonic acid core to various side chains. The structural diversity of this linker moiety, as well as the side chains attached to it, was investigated and found to significantly impact the toxicity of these compounds in MM cells. The most potent inhibitor CML-07-119(13c)(I) was evaluated in mouse and rat for liver toxicity and systemic exposure, resp., providing further optimism for the potential value of such compounds as human therapeutics.

Goldfeld, David J.; Silver, Eric S.; Radlauer, Madalyn R.; Hillmyer, Marc A. published the artcile< Synthesis and Self-Assembly of Block Polyelectrolyte Membranes through a Mild, 2-in-1 Postpolymerization Treatment>, Computed Properties of 1592-20-7, the main research area is self assembly polyelectrolyte membrane mild postpolymn.

Block polymer systems containing spatially separated pos. and neg. charges are desirable for a number of applications, including biomedical devices, membrane separations, and coatings. Unfortunately, the tendency of pos. and neg. block polymers to charge cancel and form an insoluble coacervate precipitate leads to processing difficulties in the fabrication of charged thin films. We use postpolymn. modifications to simultaneously add both neg. and pos. charges to self-assembled neutral ABC triblock polymer thin films. Using reversible addition-fragmentation chain transfer polymerization, we synthesized triblock terpolymers consisting of poly(Pr styrene sulfonic ester), poly(4-chlorostyrene), and poly(vinylbenzyl chloride). The chem. functionalization of both charged blocks was accomplished simultaneously through exposure to gaseous trimethylamine in a single step at room temperature, simplifying the synthetic procedure and preserving the microstructure of the thin film. The quant. functionalization was tracked through attenuated total reflectance IR spectroscopy, and the thin film morphol. was evaluated using intermodulation at. force microscopy, transmission electron microscopy, and grazing-incidence small-angle X-ray scattering.

Chen, Zixu; Sun, Ruixue; Feng, Shengyu; Wang, Dengxu; Liu, Hongzhi published the artcile< Porosity-Induced Selective Sensing of Iodide in Aqueous Solution by a Fluorescent Imidazolium-Based Ionic Porous Framework>, COA of Formula: C9H9Cl, the main research area is porosity fluorescence imidazolium sensor iodide framework; imidazolium; iodide sensing; paper sensor; porous polymers; silsesquioxane.

Developing a chemosensor for rapid, sensitive, and visual detection of iodide (I-) by a simple synthetic strategy is still challenging. Herein, the authors report a highly efficient iodide sensor by simply introducing ionic imidazolium groups into the porous network. This sensor, i.e., a fluorescent ionic porous framework (IPF), was prepared by the quaternization reaction of octa((benzylchloride)ethenyl)silsesquioxane and 1,4-bis(1H-imidazole-1-yl)benzene and exhibited moderate porosity with a Brunauer-Emmett-Teller surface area of 379 m2 g-1 and blue fluorescence when excited by UV light. The IPF suspension in water can detect I- with high sensitivity and selectivity among various anions and quick response by fluorescence quenching. In contrast to no response toward I- by the linear model compound and the enhanced sensing performance with an increment of porosity, this finding indicates that the porosity of IPF is important for the detection of I- and an inducement of the sensing process. A fluorescent paper sensor was further developed, which shows high efficiency for the visual detection of I- similar to the abovementioned sensor, suggesting its potential in convenient and on-site sensing of I-. In addition, the paper sensor is recyclable with a remarkable fluorescence resuming ratio of 83% after 10 times cycle detection. Moreover, the developed sensor is used for the anal. of real samples. This work represents the first example of the detection of I- by an ionic porous polymer. Compared with conventional iodide sensors, the present sensor does not require unique structures to form the pseudocavity during sensing I- and can easily achieve high efficiency by incorporating ionic hydrogen bond donors into the porous network, indicating the importance of porosity and the feasibility of replacing the pseudocavity with a real cavity (or pore). More iodide sensors with high efficiency can be designed and fabricated by this novel and simple strategy.

Franchini, Davide; Dapiaggi, Federico; Pieraccini, Stefano; Forni, Alessandra; Sironi, Maurizio published the artcile< Halogen bonding in the framework of classical force fields: The case of chlorine>, Recommanded Product: 1-Chloro-3,5-difluorobenzene, the main research area is aryl chloride alanine halogen bonding Van der Waals force.

Halogen bonding is nowadays a consolidated tool in chem. Only recently, the importance of halogen bonding has been demonstrated also in biol. systems, owing to the presence of halogens in drugs. This interaction is due to the anisotropy of the electron d. around the halogen that leads to the formation of the ‘σ-hole’, which is responsible for the interaction with a nucleophile site. Unfortunately, classical force fields used in the study of ligand-receptor systems are not able to describe the ‘σ-hole’. Here, we propose a pseudo-atom based methodol. able to correctly describe halogen bonding involving chlorine using classical force field.

Efficient chem. fixation of carbon dioxide (CO2) into valuable fine chems. requires porous materials with highly active catalytic centers. Herein, multifunctional imidazolium based hypercrosslinked ionic polymers with versatile functional groups (sulfonic, hydroxyl, amino, carboxyl, and alkyl group), abundant microporosity and high ionic site d. were constructed in a two-step solvothermal route including free-radical copolymerization of divinylbenzene (DVB), 4-vinylbenzyl chloride (VBC) and imidazolium bromide ionic liquids (ILs) and successive Friedel-Crafts alkylation based hypercrosslinkage. The resultant hydroxyl-functional ionic polymer demonstrated promising performances in selective adsorption and conversion of CO2 via cycloaddition with epoxide. High yield associating with large turnover number (TON) and turnover frequency (TOF), stable reusability and well substrate compatibility were achieved, affording an efficient metal-free heterogeneous catalyst for CO2 fixation. The full microporous structure resulted in CO2 enrichment around the robust hydroxyl-functional ionic sites, showing a synergistic effect to promote CO2 transformation.

New asym. aromatic dichlorophthalimide monomers containing pendant groups (trifluoromethyl or methyl) were conveniently prepared from inexpensive and com. available compounds With these monomers, a new class of soluble polyimides with a regioirregular structure within the polymer backbone was obtained by the Ni(0)-catalyzed polymerization method. The structures of the polymers were confirmed by various spectroscopic techniques. The polyimides displayed better solubility and higher thermal stability than the corresponding regular polyimides. In addition, fluorinated polyimides in this study had low dielec. constants ranging from 2.52 to 2.78, low moisture absorptions of less than 0.59%, and low thermal expansion coefficients between 10.6 and 19.7 ppm/°C. The oxygen permeability coefficients and permeability selectivity of oxygen to nitrogen of the films were in the ranges of 2.99-4.20 barrer and 5.55-7.50, resp. We have demonstrated that the synthetic pathway for polyimides provides a successful approach to increasing the solubility and processability of polyimides without sacrificing their thermal stability.
