Formation and reactivity of inorganic and organic chloramines and bromamines during oxidative water treatment was written by Heeb, Michele B.;Kristiana, Ina;Trogolo, Daniela;Arey, J. Samuel;von Gunten, Urs. And the article was included in Water Research in 2017.Electric Literature of C6H5ClO2 The following contents are mentioned in the article:

The formation and further reactions of halamines during oxidative water treatment can be relevant for water quality. In this study, we investigated the formation and reactivity of several inorganic and organic halamines (monochloramine, N-chloromethylamine, N-chlorodimethylamine, monobromamine, dibromamine, N-bromomethylamine, N,N-dibromomethylamine, and N-bromodimethylamine) by kinetic experiments, transformation product anal., and quantum chem. computations. Kinetic model simulations were conducted to evaluate the relevance of halamines for various water treatment scenarios. Halamines were quickly formed from the reaction of chlorine and bromine with ammonia or organic amines. Species-specific second-order rate constants for the reaction of chlorine and bromine with ammonia, methyl- and dimethylamine were in the order of 10⁶-10⁸ M^-1s^-1. The formed halamines were found to be reactive towards phenolic compounds, forming halogenated phenols via electrophilic aromatic substitution (phenol and resorcinol) or quinones via electron transfer (catechol and hydroquinone). At near neutral pH, apparent second-order rate constants for these reactions were in the order of 10^-4-10^-1 M^-1s^-1 for chloramines and 10¹-10² M^-1s^-1 for bromamines. Quantum chem. computations were used to determine previously unknown aqueous pK_a values, gas phase bond dissociation energies (BDE) and partial at. charges of the halamines, allowing a better understanding of their reactivities. Kinetic model simulations, based on the results of this study, showed that during chlorination inorganic and organic chloramines are the main halamines formed. However, their further reactions with organic matter are outcompeted kinetically by chlorine. During ozonation, mainly inorganic bromamines are formed, since ozone quickly oxidizes organic amines. The further reactions of bromamine are typically outcompeted by ozone and thus generally of minor importance. The use of peracetic acid for saline ballast water treatment can result in the formation of substantial amounts of bromamines, which can react with dissolved organic matter and contribute to the formation of brominated products. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Electric Literature of C6H5ClO2).

4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides are versatile building blocks in organic chemistry.

The presence of alk. phosphatases has been observed in several species and has been known to play a crucial role in various biol. functions. Higher expressions of alk. phosphatase have been found in several multifactorial disorders and cancer patients, which has led it to be an interesting target for drug discovery. A strong structural similarity exists between intestinal alk. phosphatases (IAPs) and tissue-nonspecific alk. phosphatases (TNAPs), which has led to the discovery of only a few selective inhibitors. Therefore, a series of 22 derivatives of 6-(chloromethyl)-4-(4-hydroxyphenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate and Et 6-(chloromethyl)-4-(2-hydroxyphenyl)-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate were synthesized to evaluate the anticancer potential of these compounds against breast cancer. The compounds were characterized through spectral and elemental analyses. The inhibitory effect of dihydropyrimidinone derivatives on alk. phosphatases was evaluated using the calf alk. phosphatase assay. The antioxidant activity of these compounds was performed to study the radical scavenging effect. In silico mol. docking and mol. dynamic simulations were performed to elucidate the binding mode of active compounds Moreover, the two-dimensional qual.-structure-activity relationship (2D-QSAR) was performed to study the structural requirements for enzyme inhibition. The calf alk. phosphatase inhibitory assay revealed significant inhibition of the enzyme by compound I with IC₅₀ 1.27μM at 0.1 mM concentration as compared to standard KH₂PO₄ having IC₅₀ 2.80μM. Several compounds also showed very good inhibition with IC₅₀ values of 2.502, 2.943, and 2.132μM, resp., at the same concentration The antioxidant assay revealed efficient radical scavenging activity of three compounds at 100μg/mL with IC₅₀ values of 0.48, 0.61, and 0.75μg/mL, resp. The mol. docking and simulation studies revealed efficient binding of active compounds in the active binding site of the target enzyme. The final QSAR equation revealed good predictivity and statistical validation having R² = 0.958 and Q² = 0.903, resp., for the generated model. The compound I showed the highest inhibitory activity with stable binding modes acting as a future lead for identifying alk. phosphatase inhibitors. The mol. simulations suggested the stable binding of this compound, and the QSAR studies revealed the importance of autocorrelated descriptors in the inhibition of alk. phosphatase. The investigated compounds may serve as potential pharmacophores for potent and selective alk. phosphatase inhibitors. We intend to further investigate the biol. activities of these compounds as alk. phosphatase inhibitors.

Discovery of boronic acid-based potent activators of tumor pyruvate kinase M2 and development of gastroretentive nanoformulation for oral dosing was written by Patle, Rajkumar;Shinde, Shital;Patel, Sagarkumar;Maheshwari, Rahul;Jariyal, Heena;Srivastava, Akshay;Chauhan, Neelam;Globisch, Christoph;Jain, Alok;Tekade, Rakesh K.;Shard, Amit.

Several studies have established that cancer cells explicitly over-express the less active isoform of pyruvate kinase M2 (PKM2) is critical for tumorigenesis. The activation of PKM2 towards tetramer formation may increase affinity towards phosphoenolpyruvate (PEP) and avoidance of the Warburg effect. Herein, we describe the design, synthesis, and development of boronic acid-based mols. as activators of PKM2. The designed mols. were inspired by existing anticancer scaffolds and several fragments were assembled in the derivatives I [R¹ = H, F, methoxy, Cl; R² = H; R³ = N(CH₃)₂, Phenyl; R⁴= H] were synthesized using a multi-step synthetic strategy in 55-70% yields, starting from cheap and readily available materials. The compounds were selectively cytotoxic to kill the cancerous cells at 80 nM, while they were non-toxic to the normal cells. The kinetic studies established the compounds as novel activators of PKM2 and I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] emerged as the most potent derivative I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] was further evaluated using various in silico tools to understand the mol. mechanism of tetramer formation. Docking studies revealed that I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] binds to the PKM2 dimer at the dimeric interface. Further to ascertain the binding site and mechanism of action, rigorous MD (mol. dynamics) simulations were undertaken, which led to the conclusion that I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] stabilizes the center of the dimeric interface that possibly promotes tetramer formation. We further planned to make a tablet of the developed mol. for oral delivery, but it was seriously impeded owing to poor aqueous solubility of I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H]. To improve aqueous solubility and retain I [R¹ = Cl; R² = H; R³ = N(CH₃)₂; R⁴= H] at the lower gastrointestinal tract, thiolated chitosan-based nanoparticles (TCNPs) were prepared and further developed as tablet dosage form to retain anticancer potency in the excised goat colon. Our findings may provide a valuable pharmacol. mechanism for understanding metabolic underpinnings that may aid in the clin. development of new anticancer agents targeting PKM2.

Synthesis of indocyanine green functionalized comblike poly(aspartic acid) derivatives for enhanced cancer cell ablation by targeting the endoplasmic reticulum was written by Wan, Jiaxun;Sun, Luyan;Wu, Pan;Wang, Fang;Guo, Jia;Cheng, Jianjun;Wang, Changchun. And the article was included in Polymer Chemistry in 2018.Formula: C6H12BrCl The following contents are mentioned in the article:

Undesired gene expression can lead to severe diseases such as cancers. Oncogenic proteins or survival factors encoded by oncogenes can sustain cancer cell survival and proliferation. Considering that proteins are manufactured and transported by the endoplasmic reticulum (ER), the destroying of oncogenic proteins within the ER could cut-off the process of undesired gene expression. In this study, a new type of ER targeting strategy was developed based on the coordination interaction of the Ca(II) ion rich ER lumen with the carboxyl group of poly(aspartic acid) (PAsp). A comblike polymer PAsp-g-(PEG-ICG) was rationally designed and successfully prepared by grafting azido-modified polyethylene glycol (PEG) and the azido-modified photosensitizer indocyanine green (ICG) onto alkynyl-modified PAsp through the copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC). Here, ICG not only shows its importance as an imaging agent that reveals the distribution of PAsp-g-(PEG-ICG) micelles both at tissue and subcellular levels, but also acts as a protein destructive agent to generate reactive oxygen species (ROS) resulting in protein denaturation. Moreover, chemotherapeutic drugs, such as paclitaxel, can be easily encapsulated into PAsp-g-(PEG-ICG) (PTX@PAsp-g-(PEG-ICG)) in up to 28% drug loading capacity with excellent stability. The exptl. results proved that the as-prepared PTX@PAsp-g-(PEG-ICG) micelles exhibited selective accumulation in the ER lumen of cancer cells. Thus, a 10-fold enhancement of ROS was obtained by incubating cancer cells with PAsp-g-(PEG-ICG) micelles at a PTX concentration of 1.0μg ml^-1 under laser irradiation (0.2 W cm^-2, 785 nm, 30 s) for 24 h, leading to disruption of proteins in the ER that caused ER stress-induced cancer cell apoptosis up to 76%. In a cytotoxicity test, U-87 MG glioma cells incubated with PTX@PAsp-g-(PEG-ICG) at the PTX concentration of 2.5μg ml^-1 were reduced to nearly 0% of cell viability upon 24 h laser irradiation (2 W cm^-2, 785 nm, 30 s), in comparison with free PTX that showed 60% cell viability under the same conditions, indicating that photodynamic therapy (PDT) remarkably enhanced chemotherapeutic effects. With the good combination of PDT and chemotherapy, the PTX@PAsp-g-(PEG-ICG) micelles offer unprecedented advantages by effectively targeting the ER and displayed a prolonged retention time in the tumors of U-87 MG bearing nude mice, providing great promise for manipulating biomaterial design to achieve the intended ER targeted delivery for non-invasive cancer therapy. This study involved multiple reactions and reactants, such as 1-Bromo-6-chlorohexane (cas: 6294-17-3Formula: C6H12BrCl).

Interaction of aqueous suspensions of single-walled oxidized carbon nanotubes with inorganic and organic electrolytes was written by Laguta, Anna N.;Mchedlov-Petrossyan, Nikolay O.;Bogatyrenko, Sergey I.;Kovalenko, Sergiy M.;Bunyatyan, Natalya D.;Trostianko, Pavlo V.;Karbivskii, Vladimir L.;Filatov, Dmitriy Yu..

This article reports the colloidal behavior of the single-walled carbon nanotubes, SWCNT, decorated by COOH groups, in water. Energy dispersive X-ray spectroscopy (EDS), XPS, and thermogravimetric anal. (TGA) methods were used to characterize the solid samples. The SWCNT suspension was characterized by dynamic light scattering (DLS) and transmission electron microscopy (TEM) methods, as well as taking into account the dependence of the electrokinetic potential ς on pH. The neg. charged particles with a diameter of an equivalent sphere about ≈ 200 nm possess a ς value of -48 mV at pH 5.7 ± 0.1. Deceleration of the reaction of cationic and anionic triphenylmethine dyes (methyl violet and nitrophenol violet, resp.) with hydroxide ion in the presence of the SWCNT was observed This effect can be associated with a lower local concentration of hydroxide ion compared to the bulk phase owing to a substantially interfacial concentration of the COO- groups. Critical coagulation concentrations, CCC, in electrolytic solutions were determined using the rate of increase in size. Coagulation with different inorganic electrolytes demonstrated that the system under study obey the Schulze-Hardy rule. Comparison with the literature data allowed confirming that the CCC for NaCl can be an effective criterion of oxidation degree of the carbon materials of this type. The coagulating influence of surface-active organic cations, including dyes, is much expressed. Besides the overcharging of the neg. charged colloidal species by cetyltrimethylammonium bromide, the same effect was revealed in the case of the cationic dyes neutral red and methyl violet, and even for the Ca²⁺ and La³⁺ cations. Methylation of the carboxylic groups, COOH → COOCH₃, of the SWCNT during 380 h, as well as heating up to 1000°C results in a substantial and sometimes opposite changes in the CCC values for different electrolytes. Along with decreasing in the CCC for NaCl, an increase in the corresponding values for multi-charged cations was observed This reveals the important role of the simultaneous interactions of multi-charged cations with several COOH (or COO-) groups in the case of the initial highly oxidized SWCNT, because this effect became less possible after methylation or removal of the carboxylic groups via heating. A substantial neg. ς-potential in aqueous media of the colloidal particles of preheated, i.e, devoid of carboxylic groups SWCNT, allows expecting an alternative charging mechanism, characteristic of oil drops and gas bubbles. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0SDS of cas: 75-57-0).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.SDS of cas: 75-57-0

The development of porous materials for ethylene (C₂H₄) separation and purification, a very important separation process in the chem. industry, is urgently needed but quite challenging. In particular, the realization of selectivity-reversed adsorption (namely, C₂H₄ is not preferentially adsorbed) and the simultaneous capture of multinary coexisting impurities such as ethane (C₂H₆) and acetylene (C₂H₂) will significantly simplify process design and reduce energy and cost consumption, but such porous materials are quite difficult to design and have not yet been fully explored. In this work, by employing an aromatic-rich bithiophene-based tetraisophthalate ligand, we solvothermally fabricated an anionic In(III)-based framework termed ZJNU-115 featuring In(COO)₄ as an inorganic secondary building unit as well as one-dimensional channels. Due to the absence of unsaturated metallic sites, together with aromatic-rich channel surface decorated with abundant hydrogen-bonding acceptors of carboxylate oxygen and thiophene sulfur atoms, desolvated ZJNU-115 exhibited an unusual adsorption relationship with respect to C₂ hydrocarbons, namely, simultaneous and preferable capture of C₂H₆ and C₂H₂ over C₂H₄ at the temperatures investigated, thus representing a rare metal-organic framework (MOF) with the promising potential for one-step adsorption-phase purification of C₂H₄ from a trinary C₂ hydrocarbon mixture Compared to a few of the MOFs reported for such an application, ZJNU-115 displayed simultaneously good adsorption selectivities of both C₂H₂ and C₂H₆ over C₂H₄. Furthermore, its separation potential can be postsynthetically tailored by substituting dimethylammonium (Me₂NH₂⁺) counterions with tetraalkyl ammonium ions (NR₄⁺; R = Me, Et, or n-Pr). More importantly, ZJNU-115 was stable in various organic solvents as well as aqueous solutions with pH values ranging from 5 to 9, thus laying a solid foundation for its practical applications. The design principle and the performance regulation strategy adopted in this work will offer valuable guidance for the contrapuntal construction of porous MOFs employed for direct multicomponent purification of C₂H₄ with improved performance.

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Electric Literature of C4H12ClN
