Three dimensional macroporous hydroxyapatite/chitosan foam-supported polymer micelles for enhanced oral delivery of poorly soluble drugs was written by Zhang, Yanzhuo;Dong, Kai;Wang, Fang;Wang, Hongtao;Wang, Jing;Jiang, Ziqiu;Diao, Shuai. And the article was included in Colloids and Surfaces, B: Biointerfaces in 2018.Electric Literature of C33H34N6O6 This article mentions the following:

In the current study, a novel three-dimensional macroporous hydroxyapatite/ chitosan foam (HA/CS)-supported polymer micelle (PM/HA/CS) was developed, and its potential as an oral drug delivery system to enhance the solubility and oral bioavailability of poorly soluble compounds was systemically studied. Candesartan cilexetil (CC) was selected as a poorly soluble model drug. Firstly, HA/CS foam was synthesized using a wet chem. co-precipitation approach and poly-(Me methacrylate) colloidal crystals as a macropore template. Subsequently, the CC-loaded polymer micelles were efficiently encapsulated into the macropores of the HA/CS foam and freeze-dried to produce powdery CC-loaded PM/HA/CS composites (CC-PM/HA/CS). The resulting CC-PM/HA/CS particles were then characterized in terms of porous structure, morphol., angle of repose, crystallinity, drug loading, dissolution profiles, and phys. stability. Differential scanning calorimetry (DSC) anal. confirmed that CC-PM/HA/CS was present in an amorphous form and has an excellent phys. stability. Under both simulated gastric and intestinal conditions, the aqueous solubility and dissolution rate of the PM/HA/CS-based CC formulation were significantly increased compared with the pure drug powder. In addition, PM/HA/CS is almost completely non-cytotoxic. The PM/HA/CS-based CC formulation produced approx. 1.9-fold increased bioavailability when compared to the marketed tablets (Blopress) administered to fasted Sprague-Dawley rats. On the whole, PM/HA/CS benefits from the advantages of three dimensional macroporous HA/CS foam and polymer micelles, and exhibits great potential as a drug delivery system for increasing the solubility and oral bioavailability of a poorly soluble compound, like CC.

Nitrogen dioxide-catalyzed oxidative bromination of benzenes and naphthalines with electron-donating substituents at room temperature was written by Ren, Yun-lai;Wang, Qian;Tian, Xin-zhe;Wang, Bin-yu;Wang, Pei. And the article was included in Fenzi Cuihua in 2014.Product Details of 25676-75-9 This article mentions the following:

Oxidative bromination of benzenes and naphthalines with electron-donating substituents was investigated by using 8.2% nitrogen dioxide as the catalyst, the residual oxygen in the reaction tube as the oxidant, and mol. bromine as the brominating reagent at room temperature The used heavy metal waste-free catalyst can be easily removed from the products and scarcely stains the final products. But a small amount of byproduct from the nitration of the benzene ring was observed, which led to the consumption of nitrogen dioxide. The reaction is highly atom economic, and a majority of bromine atoms in bromine source were transferred to the bromination products. The bromination was controllable: mono- and di-bromination products were controllably obtained by changing the loading amount of the brominating reagent. Preliminary mechanistic investigation suggests that the bromination firstly undergoes the reaction between mol. bromine and aromatic ring to give aryl bromide and HBr, which is followed by oxygenation of the resulting bromine hydride to form the reactive bromine under the catalysis of the catalytic species.

The infrared spectra of some simple benzimidazoles was written by Morgan, K. J.. And the article was included in Journal of the Chemical Society in 1961.Related Products of 4887-83-6 This article mentions the following:

The spectra of solid specimens of the simple alkyl and perfluoroalkylbenzimidazoles are characterized by a series of strong, broad bands in the region 2400-3200 cm.-1 They show no band in the region normally associated with the simple N-H stretching frequency. The alkyl and perfluoroalkyl groups are 2-Me, Et, 2-Pr, 2-iso-Pr, 4-Me, 5-Me, 2,5-Me2, 2-CF3, 2-C2F5, 2-C3F7, 4-CF3, 5-CF3, 2-Me-4-CF3, 4-Me-2-CF3, 4-Me-2-Pr, 2,4-(CF3)2, 2,5-(CF3)2, 2-Me-4,5-(CF3)2 2,4,5-(CF33, 5-MeO-2-CF3, 4,5,6,7-F4-2-CF3. Strong bands near 2400-3200 cm.-1 are ascribed to a strong H bond of the type N-H. . .N, showing proton transfer. The position of the N-H bands of the spectra of solutions of benzimidazoles is similar to that found for pyrroles and indoles. The bands show typical displacements when tetrachloroethylene replaces CH2Cl2 as solvent. Small increases in the frequency of the alkyl derivatives and large decreases in frequency of the perfluoroalkyl compounds diminish as the orientation of substitution varies 2 > 4 鈮?5. These shifts are mainly due to induction, and there is little H bonding to adjacent F atoms. Compounds with perfluoralkyl substituents show more intense absorption, giving higher values of extinction coefficients and broader bands. Spectra of perimidine, 2-methyl-, 2-ethyl-, and 2-propylperimidine show broad banded absorption from 2400 to 3200 cm.-1 In solution spectra these bonded IV-H bands are replaced by sharp bands near 3400 cm.-1 Benzimi- dazole-2-acetic acid and difluoroacetic acid have spectra indicating a strongly bonded carbonyl group and discrete OH and NH groups. In 尾-(2-benzimidazolyl)propionic acid the carbonyl is replaced by a broad band at 1550 cm.-1 and the C-O stretching frequency is displaced to 1410 cm.-1 This compound is regarded as zwitterionic. 2-Benzimidazolecarboxylic acid has a bonded carbonyl group but shows no discrete OH or amino bonds. 5-Trifluoromethyl-2-benzimidazolecarboxylic acid is similar, and a low carbonyl frequency suggests that the 4-trifluoromethyl analog is best written as a nonbonded compound In the experiment, the researchers used many compounds, for example, 7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6Related Products of 4887-83-6).

Adjacent lone pair (ALP) effects in heteroaromatic systems. 2. Isotope exchange of ring hydrogens in nitro- and fluoroimidazoles was written by Takeuchi, Yoshio;Kirk, Kenneth L.;Cohen, Louis A.. And the article was included in Journal of Organic Chemistry in 1978.Recommanded Product: 3034-41-1 This article mentions the following:

The ring protons of nitro- and fluoroimidazoles (and their N-Me derivatives) undergo base-catalyzed exchange in D2O by a combination of carbanion (C) and ylide (Y) pathways, which involve proton abstraction from the neutral imidazole species and from the imidazolium ion, resp. In 4-substituted imidazoles, C exchange occurs more readily at C-5 than at C-2, log kC correlating with 蟽o掳 for the NH- and with 蟽p掳 for the N-Me series. For 1-methyl-4-nitroimidazole, t1/2 = 2 min at C-5 (50掳, 0.2 N NaOD). In 1-methyl-5-X-imidazoles, exchange at C-4 occurs only via the Y pathway, carbanion formation in the neutral species being retarded by the adjacent lone pair (ALP) effect at N-3. The same effect is seen in the lack of C exchange at C-4 in 1-methylimidazoles. The ALP effect is considerably weaker or nonexistent at C-2. Most exchanges across the ring show correlations of log k with 蟼m掳. 4-Alkylimidazoles (but not 1,4-dialkylimidazoles) show enhanced C exchange at C-5, which may result from the existence of a trace concentration of the ketimine tautomer. Enhanced exchange at C-5 in 2-fluorohistidine is ascribed to a combination of the ketimine effect, C exchange involving catalysis by OH and intramol. general-base catalysis by the side-chain primary-amine function. The use of buffer catalysis for the T labeling of poorly reactive imidazoles is described.

And the article was included in RSC Advances in 2015.Product Details of 92507-97-6 This article mentions the following:

Two novel paramagnetic ionic liquids, comprised of a 1-ethyl-2,3-dimethylimidazolium (Edimim) cation and a tetrahaloferrate(III) (FeX4) (X = Cl and Br) anion were synthesized and characterized by thermal, structural, Raman spectroscopy and magnetic studies. The crystal structures, determined by synchrotron X-ray powder diffraction and single crystal X-ray diffraction at 100 K for Edimim[FeCl4] and Edimim[FeBr4] resp., are characterized by layers of cations (in non-planar configuration) and anions stacked upon one another in a three-dimensional (3D) manner with several non-covalent interactions: halide-halide, hydrogen bond and anion-蟺. Magnetization measurements show the presence of three-dimensional antiferromagnetic ordering below the N茅el temperature (TN) with the existence of a noticeable magneto-crystalline anisotropy in the bromide compound The corresponding magneto-structural correlations evidence that the 3D magnetic ordering mainly takes place via Fe-X路路路X-Fe (X = Cl and Br) interactions, displaying a higher superexchange magnetic interaction between the planes. Comparison with the Emim[FeX4] (X = Cl and Br) phases (Emim: 1-ethyl-3-methylimidazolium) reveals that the methylation at the C(2) position onto the imidazolium cation ring causes an increase of the m.p. and a decrease of the TN. In contrast, the comparative study with Dimim[FeX4] (X = Cl and Br) compounds (Dimim: 1,3-dimethylimidazolium) shows a lower TN in the chloride compound, Edimim[FeCl4], whereas it is higher for the bromide, Edimim[FeBr4]. This fact is attributed to the spin delocalization of iron atoms in [FeBr4] and discards the hypothesis that a bigger imidazolium ion size causes a weaker magnetic coupling in paramagnetic ionic liquids based on tetrahaloferrate anions and imidazolium cations with 3D magnetic ordering in its solid state.

However, volatile organic solvents are usually used, which may disturb the liquid-liquid interface and affect the COF membrane crystallinity due to solvent evaporation Simultaneously, the domain size of the organic solvent-water interface, named the reaction zone, can hardly be regulated, and the diffusion control of monomers for favorable crystallinity is only achieved in the water phase. These drawbacks may limit the widespread applications of liquid-liquid interfacial polymerization to synthesize diverse COF membranes with different functionalities. Here, we report a facile strategy to synthesize a series of imine-linked freestanding COF membranes with different thicknesses and morphologies at tunable ionic liquid (IL)-H2O interfaces. Due to the H-bonding of the catalysts with amine monomers and the high viscosity of the ILs, the diffusion of the monomers was simultaneously controlled in water and in ILs. This resulted in the exceptionally high crystallinity of freestanding COF membranes with a Brunauer-Emmett-Teller (BET) surface area up to 4.3 times of that synthesized at a dichloromethane-H2O interface. By varying the alkyl chain length of cations in the ILs, the interfacial region size and interfacial tension could be regulated to further improve the crystallinity of the COF membranes. As a result, the as-fabricated COF membranes exhibited ultrahigh permeance toward water and organic solvents and excellent selective rejection of dyes. In the experiment, the researchers used many compounds, for example, 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide).

3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide (cas: 404001-48-5) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole also acts as a microtubule destabilizing agents and inhibits topoisomerase and Cytochrome P450 Family 26 Subfamily A Member 1 (CYP26A1) enzymes.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide
