Inhibitors of Bromodomain and Extra Terminal (BET) proteins were investigated for various therapeutic indications, but selectivity for BRD2, BRD3, BRD4, BRDT and their resp. tandem bromodomains BD1 and BD2 remains suboptimal. Here, selectivity-focused structural modifications of previously reported dihydropyridine lactam to form 7-alkyl-1-ethyl-5-(p-tolyl)-5,7,8,9-tetrahydro-1H-pyrrolo[3′,4′:5,6]pyrido[2,3-d]pyrimidine-2,4,6(3H)-triones I [R = CH₂Ph, CH₂Bn, PhOCH₂CH₂, etc.] by changing linker length and linker type of the lactam side chain in efforts to engage the unique arginine 54 (R54) residue in BRDT-BD1 to achieve BRDT-selective affinity was reported. It was found that the analogs were highly selective for BET bromodomains and generally more selective for the first (BD1) and second (BD2) bromodomains of BRD4 rather than for those of BRDT. Based on AlphaScreen and BromoScan results and on crystallog. data for analog I [R = CH₂CH(CH₂CH₂NCH₂CH₂)CH₂(4-O₂NC₆H₄)], we concluded that the lack of selectivity for BRDT is most likely due to the high flexibility of the protein and the unfavorable trajectory of the lactam side chain that do not allow interaction with R54. A 15-fold preference for BD2 over BD1 in BRDT was observed for analogs I [R = CH₂CH(CH₂CH₂NCH₂CH₂)CH₂C(O)Ph], I [R = CH₂CH₂(3-MeOC₆H₄)] which was supported by protein-based ¹⁹F NMR experiments with a BRDT tandem bromodomain protein construct.

Combining of modified QuEChERS and dispersive liquid-liquid microextraction as an efficient sample preparation method for extraction of acetamiprid and imidacloprid from pistachio samples was written by Khanehzar, Hasan;Faraji, Mohammad;Nezhadali, Azizollah;Yamini, Yadollah. And the article was included in Journal of the Iranian Chemical Society in 2021.Recommanded Product: 5137-55-3 The following contents are mentioned in the article:

In this research, for the first time, the QuEChERS was combined with the dispersive liquid-liquid microextraction based on deep eutectic solvent (QuEChERS-DES-DLLME). The method was developed for efficient extraction, clean-up and preconcentration of acetamiprid (ACE) and imidacloprid (IMI), two commonly used pesticides, from pistachio samples before their determination by HPLC-UV. The pesticides were firstly extracted from pistachio samples and cleaned-up by QuEChERS, and then their supernatant was used as a dispersant in following DLLME in order to further purification and preconcentration The extraction solvent used in DLLME was based on deep eutectic solvents (DESs). Preparation of hydrophobic DES was done by mixing amyl alc. as hydrogen bond donor and trioctylmethylammonium chloride (TOMAC) as hydrogen bond acceptor. Different parameters that affect the efficiency of the two steps were evaluated and optimized. Under optimal conditions, the limit of detections was 1.5 and 3.0μg kg-1 for ACE and IMI and the limit of quantification was 1.5 and 4.5μg kg-1 for ACE and IMI, resp. Calibration curves were linear in the range 5.0-500μg kg-1 with correlation coefficients higher than 0.99. Preconcentration factor for ACE and IMI was 16 and 13, resp. The intraday and interday precisions at concentration levels of 10 and 100μg kg-1 were less than 7.0%. Finally, applicability of the suggested method was investigated through anal. of the analytes in some pistachio samples, and the obtained relative recoveries (95.6-99.4%) were acceptable. The good sensitivity and suitable purification in the anal. of the pistachio samples, as a complex food matrix, are obtained using the proposed method by combining the advantages of QuEChERS and DLLME.

And the article was included in Separation and Purification Technology in 2022.HPLC of Formula: 13820-53-6 The following contents are mentioned in the article:

The present study developed bifunctional catalyst for CO₂ hydrogenation into di-Me ether (DME), whereby it consists of Pd/In₂O₃ for CO₂ hydrogenation into methanol, and H-ZSM-5 for methanol dehydration into DME. The catalyst development was focused on the synthesis of Pd/In₂O₃ via a green and low-cost synthesis method of carbonized alginate templating. Thus, microspherical-confined nano-Pd/In₂O₃ was formed, whereby the localized nucleation growth was coordinated by the chem. entrapped In³⁺ via ionic bond in the well-distributed alginate structure. It was found that hydrothermal temperature plays a key role in the development of this catalyst structure. The optimum hydrothermal temperature is 160°C, as it is able to produce the highest amount of methanol. This catalyst was further integrated with H-ZSM-5 via different integration manners. It was found that mortar mixed method produces the highest amount of DME, as the close proximity causes stronger ion-exchange mechanism between the catalyst components, which facilitates higher oxygen vacancy d. in the bifunctional catalyst. Under the optimum Pd/In₂O₃: H-ZSM-5 (PdIn-160-12: H-ZSM-5) mass ratio of 4:1, the highest STY_DME of 79.7 g_DME kg^-1_cat h^-1 with CO₂ conversion of 9% and DME selectivity of 44.1% can be achieved. In addition, the STY_DME can be maintained even in 60 h on stream, demonstrating the excellent stability and performance of microspherical-confined nano-Pd/In₂O₃/H-ZSM-5 bifunctional catalyst synthesized via carbonized alginate templating strategy.

Second-generation chiral-substituted poly-N-vinylpyrrolidinones (CSPVPs) (-)-1R and (+)-1S were synthesized by free-radical polymerization of (3aR,6aR)- and (3aS,6aS)-5-ethenyl-tetrahydro-2,2-dimethyl-4H-1,3-dioxolo[4,5-c]pyrrol-4-one, (I and II, resp.), using thermal and photochem. reactions. They were produced from resp. D-isoascorbic acid and D-ribose. In addition, chiral polymer (-)-2 was also synthesized from the polymerization of (S)-3-(methoxymethoxy)-1-vinylpyrrolidin-2-one (III). Mol. weights of these chiral polymers were measured using HRMS, and the polymer chain tacticity was studied using ¹³C NMR spectroscopy. Chiral polymers (-)-1R, (+)-1S, and (-)-2 along with poly-N-vinylpyrrolidinone (PVP, MW 40K) were sep. used in the stabilization of Cu/Au or Pd/Au nanoclusters. CD spectra of the bimetallic nanoclusters stabilized by (-)-1R and (+)-1S showed close to mirror-imaged CD absorption bands at wavelengths 200-300 nm, revealing that bimetallic nanoclusters’ chiroptical responses are derived from chiral polymer-encapsulated nanomaterials. Chemo-, regio-, and stereo-selectivity was found in the catalytic C-H group oxidation reactions of complex bioactive natural products, such as ambroxide, menthofuran, boldine, estrone, dehydroabietylamine, 9-allogibberic acid, and sclareolide, and substituted adamantane mols., when catalyst Cu/Au (3:1) or Pd/Au (3:1) stabilized by CSPVPs or PVP and oxidant H₂O₂ or t-BuOOH were applied. Oxidation of (+)-boldine N-oxide 23 using NMO as an oxidant yielded 4,5-dehydroboldine 27, and oxidation of (-)-9-allogibberic acid yielded C6,15 lactone 47 and C6-ketone 48.

Conductometric Probe Analysis of the Effect of Benzyldimethylhexadecylammonium Chloride on the Micellization Behavior of Dodecyltrimethylammonium Bromide in Aqueous/Urea Solution: Investigation of Concentration and Temperature Effect was written by Molla, Mohammad Robel;Rana, Shahed;Abdul Rub, Malik;Ahmed, Anwar;Hoque, Anamul Md.. And the article was included in Journal of Surfactants and Detergents in 2018.Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Surfactant mixtures are used in many different industrial formulations. In this study, the mixed micelle formation behavior of 2 different cationic surfactants, namely dodecyltrimethylammonium bromide (DTAB) and benzyldimethylhexadecylammonium chloride (BDHAC), in the absence and presence of urea at various temperatures (298.15-318.15 K) was studied using the conductometric method. The attractive interaction between DTAB and BDHAC was estimated from the values of critical micelle concentration (CMC) and the CMC for ideal mixing (CMC^id). Urea increases the CMC value as a result of the enrichment in the surface charge of the micelles/mixed micelles. The values of micellar mole fraction (X₁^Rub [Rubingh], X₁^M [Motomura], X₁^Rod [Rodenas]) and ideal micellar (X₁^id) of surfactant BDHAC were obtained by different models and are shown to exhibit the high contribution or effective involvement of BDHAC in mixed micelles and increase with increasing BDHAC mole fraction (a₁). Activity coefficients (f₁ and f₂) were also evaluated from the relevant formula given in the literature. The neg. values of the interaction parameters (β) show the attractive interaction among the studied components. Excess Gibbs free energy ([Δ]G_ex) of micellization revealed that the stability of mixed micelles is higher in aqueous solution than in urea solution The thermodn. parameters, namely the Gibbs free energy change, enthalpy change, and entropy change ([Δ]G^o_m, ΔH^o_m, and [Δ]S^o_m, resp.), were also calculated from the conventional standard equations.

A critical challenge in the enrichment of active ingredients in natural medicines is the design of adsorbents with high selectivity and adsorption capacity. Covalent organic frameworks (COFs), which have adjustable pores and high sp. surface areas, could be effective as adsorbents for active ingredients. This study used an environmentally friendly deep eutectic solvent (DES) instead of organic solvents as the reaction solvent, and high-crystallinity COF-DES was successfully prepared The COF-DES fabricated using 1,3,5-tris(4-aminophenyl)benzene and 2,5-dihydroxyterephthalaldehyde as building blocks showed good dispersibility, large surface area (444.56 m²·g^-1), and suitable pore size (25.9 Å). Owing to its unique structure and functional group properties, COF-DES can prevent interferences from other compounds such as alkaloids, resulting in outstanding selective adsorption performance for flavonoids. Furthermore, under optimized adsorption conditions, the adsorption effects of the COF-DES on flavonoids were much better than those of the effects of macroporous resins, indicating the potential of the COF-DES as a selective adsorbent for flavonoids. Finally, a flavonoid-possessing rich natural medicine, Abelmoschus manihot (Linn.) Medicus flower, was used as a sample to study the application potential of the COF-DES. The results showed that the COF-DES had good adsorption and selection capability for flavonoids in actual samples. Moreover, compared with solid-phase extraction (SPE) columns based on macroporous resins, a COF-DES based SPE column showed superior adsorption performance for an actual complex sample, indicating the potential to COF-DES as an effective adsorbent alternative to macroporous resins. Addnl., the COF-DES had great com. value as an adsorbent for SPE flavonoid columns.

Separation of Re(VII) from Mo(VI) using biomaterial-based ionic gel adsorbents: Extractive adsorption enrichment of Re and surface blocking of Mo was written by Li, Wenjing;Dong, Xuelin;Zhu, Lihua;Tang, Heqing. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020.Formula: C25H54ClN The following contents are mentioned in the article:

It is urgently needed to develop highly efficient and selective adsorbents for enrichment and separation of Re(VII) from Mo(VI) to obtain metallic rhenium. By tuning cross-link of chitosan, ionic gel capsules (CSN) were prepared, which had a core-shell structure and wrapped N263 (Me trioctyl ammonium chloride) as an extractant. After being characterized, the CSN capsules were used as a green adsorbent for separation of ReO^–₄ from MoO^2-₄. It was found that the gel yielded good adsorption capacities for Re(VII) in a wide pH range from pH 2 to 12. The adsorption of Re(VII) on the gel followed the Langmuir model, exhibiting a maximum adsorption capacity of 222 mg g^-1 for Re. The adsorbent showed good adsorption capacities for Mo(VI) at pH < 2, but little at pH > 3.5. Therefore, the enrichment and separation of Re(VII) from Mo(VI) could be easily achieved by using the gel adsorbent in a wide pH range from 4 to 12, showing a separation factor β_Re/Mo with values of 10³-5 × 10⁴. A mechanism was proposed for the selective adsorption of Re(VII). The extractant N263 wrapped in the capsule core provides excellent extractive adsorption ability for Re(VII) through ion association extraction, generating ion association complex R₄N⁺•ReO^–₄ in the adsorbent. The gel shell was composed of cross-linked chitosan induced by sodium tripolyphosphate, and functioned as a blocking layer for the adsorption of Mo(VI), being possibly related to a special interaction between Mo and P as observed in the formation of phosphorus molybdenum heteropolyacid and/or the crosslinking with Mo and chitosan. The CSN gel was successfully applied to sep.

And the article was included in Journal of Macromolecular Science in 2017.Safety of 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine The following contents are mentioned in the article:

We prepared two series of nanosized polymers containing s-triazine moiety by reactions of newly prepared substituted diacids chlorides derived from 2-anilino-4,6-di-(phenoxy)- and 2-(N-1-naphthylamine)-4,6-di-(phenoxy)-s-triazines with a number of com. diamines. The polymers were carefully characterized by different techniques including IR, UV, fluorescent emission, elemental and thermal analyses and SEM (SEM). The SEM images indicated that most of the polyamides were organized as well defined nano sized spheres, but in certain derivatives small amount of aggregated nanospheres was also observed Structure-property correlations based on a single or more interchange proved to be feasible. The polymers exhibited high thermal behavior and, based on the produced char yields, the limiting oxygen index (LOI) indicated that a dozen polymers were classified as “slow burning polymers” while the other dozen polymers were “self-extinguishing polymers”. Polymers derived from sym. diamine exhibited better thermal stability than those containing asym. diamines. Interestingly, while the naphthyl/phenyl interchange has no influence on the thermal properties in some cases, however, dramatic improvements were noticed in many other cases. Obviously, the pyridine/phenylene interchange has no influence on the thermal properties of the addressed polymers. The polymers exhibited emissions ranging from blue to orange wavelength depending on the nature of the signaling unit. While the introduction of a naphthyl moiety has no significant influence on the electronic properties in some cases, however, the interchange led to either appreciable red-shifted absorptions or disrupt the conjugation and thus blue-shifted absorptions in other analogs. This result enables such polymers as good candidates in different technol. applications.

Influence of in Vitro Assay Setup on the Apparent Cytotoxic Potency of Benzalkonium Chlorides was written by Groothuis, Floris A.;Timmer, Niels;Opsahl, Eystein;Nicol, Beate;Droge, Steven T. J.;Blaauboer, Bas J.;Kramer, Nynke I.. And the article was included in Chemical Research in Toxicology in 2019.Quality Control of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

The nominal concentration is generally used to express concentration-effect relationships in in vitro toxicity assays. However, the nominal concentration does not necessarily represent the exposure concentration responsible for the observed effect. Surfactants accumulate at interphases and likely sorb to in vitro system components such as serum protein and well plate plastic. The extent of sorption and the consequences of this sorption on in vitro readouts is largely unknown for these chems. The aim of this study was to demonstrate the effect of sorption to in vitro components on the observed cytotoxic potency of benzalkonium chlorides (BAC) varying in alkyl chain length (6-18 carbon atoms, C6-18) in a basal cytotoxicity assay with the rainbow trout gill cell line (RTgill-W1). Cells were exposed for 48h in 96-well plates to increasing concentration of BACs in exposure medium containing 0, 60 μM Bovine Serum Albumin (BSA) or 10% fetal bovine serum (FBS). Before and after exposure, BAC concentrations in exposure medium were anal. determined Based on freely dissolved concentrations at the end of the exposure, median effect concentrations (EC₅₀) decreased with increasing alkyl chain length up to 14 carbons. For BAC with alkyl chains of twelve or more carbons, EC₅₀s based on measured concentrations after exposure in supplement-free medium were up to 25-times lower than EC₅₀ calculated using nominal concentrations When BSA or FBS was added to the medium, a decrease in cytotoxic potency of up to 22 times was observed for BAC with alkyl chains of eight or more carbons. The results of this study emphasize the importance of expressing the in vitro readouts as a function of a dose metric that is least influenced by assay setup to compare assay sensitivities and chem. potencies.
