Synthesis and structure-activity relationship of coumarins as potent Mcl-1 inhibitors for cancer treatment was written by Xia, Yang-Liu;Wang, Jing-Jing;Li, Shi-Yang;Liu, Yong;Gonzalez, Frank J.;Wang, Ping;Ge, Guang-Bo. And the article was included in Bioorganic & Medicinal Chemistry in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

In this study, more than thirty coumarin derivatives I (R₁ = H, NO₂; R₂ = Me, CF₃, Ph, etc.; R₃ = H, CH₂NMe₂, CH₂N(CH₂)₄CHOH; R₄ = OH, OMe, Cl, etc.; R₅ = H, OH, OMe; R₆ = H, OH, NO₂, etc.) with different substituents were designed and synthesized, and their Mcl-1 inhibitory activities evaluated using a fluorescence polarization-based binding assay. The results showed that the catechol group was a key constituent for Mcl-1 inhibitory activity of the coumarins, and methylation of the catechol group led to decreased inhibitory activity. The introduction of a hydrophobic electron-withdrawing group at the C-4 position of 6,7-dihydroxycoumarin, enhanced Mcl-1 inhibitory capacity, and a hydrophilic group in this position was unbeneficial to the inhibitory potency. Among all coumarins tested, I (R₁ = H; R₂ = CF₃; R₃ = H; R₄ = OH; R₅ = OH; R₆ = H) displayed the most potent inhibitory activity towards Mcl-1 (K_i = 0.21 ± 0.02μM, IC₅₀ = 1.21 ± 0.56μM, resp.), for which the beneficial effect on taxol resistance was also validated in A549 cells. A strong interaction between I (R₁ = H; R₂ = CF₃; R₃ = H; R₄ = OH; R₅ = OH; R₆ = H) and Mcl-1 in docking simulations further supported the observed potent Mcl-1 inhibition ability of I (R₁ = H; R₂ = CF₃; R₃ = H; R₄ = OH; R₅ = OH; R₆ = H). 3D-QSAR anal. of all tested coumarin derivatives further provides new insights into the relationships linking the inhibitory effects on Mcl-1 and the steric-electrostatic properties of coumarins.

Structure basis for the inhibitory mechanism of a novel DNase γ-specific inhibitor, DR396 was written by Sunaga, Satoshi;Yoshimori, Atsushi;Shiokawa, Daisuke;Tanuma, Sei-ichi. And the article was included in Bioorganic & Medicinal Chemistry in 2006.Electric Literature of C9H6Cl2N4 The following contents are mentioned in the article:

DNase γ, a member of the DNase I family, has been suggested to cause DNA fragmentation during apoptosis. The authors recently identified 4-(4,6-dichloro-[1,3,5]-triazine-2-ylamino)-2-(6-hydroxy-3-oxo-3H-xanthen-9-yl)-benzoic acid (DR396) as a novel specific inhibitor for human DNase γ. However, the binding mode (coordinate) of DR396 to DNase γ has not yet been defined. Here, the authors examined the mol. basis for the inhibitory activity of DR396 to DNase γ by structure-based computational docking studies. In the blind-docking study using a human DNase γ homol. model, a unique binding site of DR396 was predicted, which is tentatively named the DNA trapping site because of the binding domain of the unhydrolyzed DNA strand, but not the active site. Targeting the DNA trapping site as a hot spot, new human DNase γ inhibitors were obtained from our diverse chem. library in silico. These inhibitors showed high correlations between their predicted binding-free energies (ΔGs) and observed IC₅₀ values in the DNA trapping site but not the active site. The IC₅₀ of a regioisomer of DR396, 5-(4,6-dichloro-[1,3,5]-triazine-2-ylamino)-2-(6-hydroxy-3-oxo-3H-xanthen-9-yl)-benzoic acid (DF365), was 73 μM (ΔG = -9.75 kcal/mol), a 20-fold weaker inhibitory ability than that of DR396 (IC₅₀ = 3.2 μM, ΔG = -11.22 kcal/mol). Fluorescein and triazine derivatives, partial structures of DR396, had little inhibitory activity for DNase γ. Docking analyses of the interaction between DR396 and DNase γ revealed that DR396 binds tightly to three subsites (S1, S2, and S3) in the trapping site of DNase γ by forming six hydrogen bonds, whereas DF365 and the partial structures are unable to form hydrogen bonds at all three subsites. These findings suggest that the specificity and potency of the inhibitory activity of DR396 for DNase γ is due to the specific interaction of DR396 with three subsites in the DNA trapping site of DNase γ. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4Electric Literature of C9H6Cl2N4).

4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning.

This article investigates the applicability of an environmentally friendly and energy efficient deep eutectic solvents (DES) for indigotin blue dye (IBD) preconcentration prior to its quantification by a UV-Visible spectrophotometer. The adsorbent (UT-mGO) is made of Fe₃O₄, graphene oxide, urea and tetramethylammonium chloride. It was prepared via dispersing magnetic graphene oxide in a DES. The adsorbent was prepared fast and easy, without consumption of dangerous reagents. The X-ray diffraction patterns show pure structures of components. The FT-IR spectra show strong interaction between DES and mGO. In addition, a scanning electron microscope confirms that DES covered the surface of mGO homogeneously. Magnetic amount and surface property were characterized by an alternating gradient force magnetometer and Brunauer-Emmett-Teller, resp. High surface area and enough magnetic property, as well as π-π and electrostatic interactions among analyte and adsorbent propose UT-mGO as a qualified candidate to preconc. IBD. Effective parameters including pH, adsorbent amount, adsorption time, eluent and desorption time were optimized. Under the optimized conditions, the method has the following figures of merit: (a) limit of detection of 1.5 × 10^-6 g L^-1, (b) relative standard deviation (n = 7) of 3.49%, (c) preconcentration factor of 50 and (d) linearity of dynamic range of 1.0 × 10^-5 to 45 × 10^-5 g L^-1. The adsorbent is not reusable but durable in six months. Isotherm model of Langmuir and kinetic model of pseudo-second-order fitted for the system. ΔH (-13.2 × 10³ J mol^-1), ΔS (5.38 J K^-1 mol^-1) and ΔG (-3.69 × 10³ – +10.9 × 103 J mol^-1) were calculated as thermodn. parameters. The method was successfully applied for IBD preconcentration from three samples of fruit juices and three samples of jelly powders.

Synergism and aggregation behavior in an aqueous binary mixture of cationic-zwitterionic surfactants: physico-chemical characterization with molecular simulation approach was written by Kanoje, Bharatkumar;Padshala, Shailesh;Parikh, Jigisha;Sahoo, Suban K.;Kuperkar, Ketan;Bahadur, Pratap. And the article was included in Physical Chemistry Chemical Physics in 2018.COA of Formula: C25H46ClN The following contents are mentioned in the article:

Aqueous interactions between a cationic surfactant benzyl dimethylhexadecylammonium chloride (BDHAC) and alkyldimethylammoniopropane sulfonates (C_nDAPS) based three zwitterionic surfactants n = 10, 12, and 14 (abbreviated as C₁₀DAPS, C₁₂DAPS and C₁₄DAPS, resp.) were studied using tensiometry, and fluorescence spectrophotometry techniques. The critical micelle concentration degree of synergism and various other parameters such as interaction parameter (β), activity coefficients (f^m) and interfacial parameters such as surface pressure (π_CMC), packing parameter (P), surface excess concentration (Γ_max), surface tension at CMC (γ_CMC), and min. area per mol. (A_min) were evaluated using the Regular Solution Theory (RST) of mixed systems. The results indicate a strong dependency on the mixed system and their composition For the quant. prediction, the mol. architecture of the surfactants in mixed systems and their synergistic interactions were investigated by computational simulation using Spartan’14 V1.1.8. The structural optimization results obtained were found to be in good agreement with the estimations made using RST. The reduction in surface tension indicates a certain efficiency in mixed micelle formation owing to electrostatic attraction between the cationic and zwitterionic surfactants. In addition, the binary surfactant systems evaluated by Maeda’s approach infer the mixed micelles are thermodynamically stable. The aggregation number (N_agg) appeared to be larger at the composition point where the efficiency of mixed micelle formation is greatest. The strength of the interaction between BDHAC and C_nDAPS followed the order: C₁₄DAPS > C₁₂DAPS > C₁₀DAPS indicating a greater synergism at 0.25 molar ratio of zwitterionic surfactants to cationic surfactants in the aqueous solution at 303.15 K.

The target compounds were first tested for cytotoxicity to determine a non-toxic concentration for antiinflammatory screening, so that the inhibitory effects against NO and PGE₂ production would not be caused by cytotoxicity. Compounds 1f (2-methoxy-6-oxo-6,7,8,9,10,11-hexahydrocyclohepta[c]chromen-3-yl 4-methylbenzenesulfonate) and 1p (2-methoxy-6-oxo-7,8,9,10,11,12-hexahydro-6H-cycloocta[c]chromen-3-yl 4-methylbenzenesulfonate) were the most active PGE₂ inhibitors with IC₅₀ values of 0.89 and 0.95 μM, resp. Western blot and cell-free COX-2 screening showed that their effects were due to inhibition of both COX-2 protein expression and COX-2 enzyme activity. Their IC₅₀ values against the COX-2 enzyme were 0.67 and 0.85 μM, resp., which is more potent than etoricoxib. The selectivity indexes of compounds 1f and 1p against COX-2 compared to COX-1 were 41.1 and 42.5, resp. Compound 1f showed strong inhibitory effects at 5 μM concentration on COX-2 mRNA expression in LPS-induced RAW 264.7 macrophages.

New methods of metal extraction from the “black mass” (BM) from spent lithium-ion batteries have been presented with ionic liquids (ILs), Deep Eutectic Solvents (DESs) and organophosphorous-based acids. The low-temperature method of extraction of cobalt, nickel, lithium and other metals without pre-leaching of BM with acids have been proposed in comparison with many methods already described in the literature. Extraction has been studied in detail with ILs: methyltrioctylammonium chloride ([N8,8,8,1][Cl], Aliquat 336), trihexyltetradecylphosphonium chloride ([P6,6,6,14][Cl], Cyphos IL 101), trihexyltetradecylphosphonium thiocyanate ([P6,6,6,14][SCN]), benzethonium tricyanomethanide ([Benzet][TCM]), as well as with DESs mixtures and well known organophosphorous-based acids: bis(2,4,4-trimethylpentyl)phosphinic acid (Cyanex 272) and di-(2-ethylhexyl) phosphoric acid (D2EHPA). It was shown that fast and efficient extraction, with 90-100 wt% recovery of Co(II), may be obtained using DESs. Well known for the extraction of metal ions from the aqueous phase ILs, binary mixtures of ILs (synergistic effect) and Aqueous Biphasic System (ABS) method with NaCl, {[P_4,4,4,14][Cl] + NaCl + Co(II)} have shown very low efficiency in the recovery of metals from BM. The extraction of cobalt (30-58 wt%) and the high extraction efficiency of lithium (41-92 wt%) and nickel (37-52 wt%) was obtained using Cyanex 272 in a mixture with di-Et phosphite. Process factors such as solvent content, extraction additivities, stripping and precipitation methods, temperature, holding time, pH and liquid/solid as well as organic/water ratios were studied. For all extractions, the selectivity and distribution ratios were described. A schematic flow chart for the selective recovery of cobalt(II), lithium(I) and nickel(II) from BM has been proposed. The presented extraction processes can compete with the costly hydrometallurgical methods for recovering metals from secondary waste.

Photo-thermo catalytic selective oxidation of cyclohexane by In-situ prepared nonstoichiometric Molybdenum oxide and Silver-palladium alloy composite was written by Wang, Xiaoyu;Feng, Xuyang;Liu, Jincheng;Huang, Zhilin;Zong, Shuang;Liu, Linlin;Liu, Jiarong;Fang, Yanxiong.

The highly selective oxidation of cyclohexane to cyclohexanone and cyclohexanol (KA oil) is one of the most challenging issues in the chem. industry. However, the difficulty in attaining high selectivity and high conversion rate in parallel for the existing catalysts limits its practical application. In this paper, a novel photo-thermo synergistic catalyst was reported for the aerobic oxidation of cyclohexane. The uniform blue MoO_3-x nanowires with small diameter stabilized by polyvinyl pyrrolidone (PVP) were synthesized by a hydrothermal method, and a series of MoO_3-x-AgPd composite materials of different proportions were prepared by an in-situ reduction process. The morphol., crystalline structure, surface chem. bonding, photoelectrochem. properties of MoO_3-x-AgPd composites are thoroughly characterized. The MoO_3-x-AgPd composites present significantly increased catalytic performance than MoO_3-x nanowires in the photo-thermo synergistic catalytic oxidation of cyclohexane under dry air. The high conversion rate of 11.3% with the KA oil selectivity of 99.0% was achieved by the MoO_3-x-Ag₂₀Pd₂₀ composites under photo-thermo catalytic process at 120 °C, which is 1.5 times of that by MoO_3-x nanowires. Under photo-thermo catalytic process, a high cyclohexane conversion rate similar to that of higher temperature thermal catalysis can be obtained at lower reaction temperature, and more cyclohexanol can be produced with a ketone to alc. (K/A) ratio of 0.254. The significantly enhanced catalytic activity can be attributed to the effective charge transfer in the AgPd alloy nanoparticles, the optimized band gap structure, the suppressed charge recombination, and the promoted photo-thermo synergetic catalytic effect. This work provides a new reference scheme for the design and preparation of high-efficiency photo-thermo catalysts for the selective oxidation of cyclohexane.

It was found that the dcnm anions transformed into ccnm anions during the reactions. These anions coordinate with the uranyl cations in chelate or terminal monodentate coordination mode, affording neg. divalent complex anions which can combine with different organic cations and form ionic uranyl-containing complexes. Plenty of C-H···O, N-H···O, C-H···N, N-H···N, and H···H weak interactions are formed in the crystal structures.

Layer-by-layer encapsulated nano-emulsion of ionic liquid loaded with functional material for extraction of Cd²⁺ ions from aqueous solutions was written by Elizarova, Iuliia S.;Luckham, Paul F.. And the article was included in Journal of Colloid and Interface Science in 2017.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Ionic liquids can serve as an environmentally-friendly replacement for solvents in emulsions, therefore they are considered suitable to be used as an emulsified medium for various active materials one of which are extractors of metal ions. Increasing the extraction efficiency is considered to be one of the key objectives when working with such extraction systems. One way to improve the extraction efficiency is to increase the contact area between the extractant and the working ionic solution This can be accomplished by creating a nano-emulsion of ionic liquid containing such an extractant. Since emulsification of ionic liquid is not always possible in the sample itself, there is a necessity of creating a stable emulsion that can be added externally and on demand to samples from which metal ions need to be extracted We propose a method of fabrication of a highly-stable extractant-loaded ionic liquid-in-water nano-emulsion via a low-energy phase reversal emulsification followed by continuous layer-by-layer polyelectrolyte deposition process to encapsulate the nano-emulsion and enhance the emulsion stability. Such a multilayered stabilized nano-emulsion was tested for extraction of Cd²⁺ and Ca²⁺ ions in order to determine its extraction efficiency and selectivity. It was found to be effective in the extraction of Cd²⁺ ions with near 100% cadmium removal, as well as being selective since no Ca²⁺ ions were extracted The encapsulated emulsion was removed from samples post-extraction using two methods – filtration and magnetic separation, both of which were shown to be viable under different circumstances – larger and mech. stronger capsules could be removed by filtration, however magnetic separation worked better for both smaller and bigger capsules. The long-term stability of nano-emulsion was also tested being a very important characteristic for its proposed use: it was found to be highly stable after four months of storage time.
