Pharmacological corrections of the mutant hERG channels by posaconazole

Properties of mutant human ether-a-go-go-related gene (hERG) channels can be modified by some antibiotics. However, the pharmacological effects of posaconazole on cardiomyocyte hERG channels remain unclear. Whole-cell patch clamping, western blotting and laser confocal scanning microscopy were used to evaluate the effects of posaconazole on wild-type (WT)-, A561V- and L539 fs/47-hERG channels expressed in human embryonic kidney (HEK) 293 cells. In electrophysiological experiments, HEK 293 cells were transiently co-transfected with equal amounts of WT-hERG, WT+A561 V-hERG and WT+L539 fs/47-hERG plasmids to mimic a heterozygous genotype. Posaconazole (30 mu M) increased tail currents in cells expressing WT-hERG, WT+A561 V-hERG and WT+L539 fs/47-hERG by 82.65%, 147.72% and 134.73%, respectively, compared to controls. Posaconazole increased hERG protein expression in cells expressing WT-hERG, WT+A561 V-hERG and WT+L539 fs/47-hERG compared to controls condition as well as their trafficking to the cell membrane. To our knowledge, this is the first study to show that antifungal agent posaconazole rescues the mutant A561 V-hERG and L539 fs/47-hERG channels by altering the gating kinetics, enhancing the expression and trafficking of hERG channels. The results demonstrate that posaconazole could be a promising candidate for the prevention and treatment of long QT syndrome and other arrhythmia-related diseases.

Fluorinated dendritic silicon (IV) phthalocyanines nanoparticles: Synthesis, photoinduced intramolecular energy transfer and DNA interaction

Two series of fluorinated and non-fluorinated dendritic silicon (IV) phthalocyanines with cyano/nitro/ester terminal functionalities have been synthesized. Their structures were characterized by elemental analysis, FT-IR, H-1 NMR and ESI-MS. The effects of fluorinated groups and terminal functionalities properties on the photo physical properties, photoinduced intermolecular electron transfer and intramolecular energy transfer of silicon phthalocyanines were compared. In order to endow water soluble and biocompatibility to these silicon phthalocyanines, an amphiphilic diblock copolymer polyethylene glycol monomethyl ether-polycaprolactone was used to encapsulate these silicon phthalocyanines to form fluorinated and non-fluorinated dendritic silicon phthalocyanines nanoparticles. The binding model between the fluorinated dendritic silicon phthalocyanines nanoparticles and calf thymus DNA was studied by UV-Vis and fluorescence spectroscopic method. The photocleavage DNA activities of three fluorinated dendritic silicon phthalocyanines nanoparticles were compared and the possible cleavage mechanism was proposed.

Facile Fabrication of Amphiphilic and Asymmetric Films with Excellent Deformability for Efficient and Stable Adsorption Applications

In this study, a facile way to prepare amphiphilic and asymmetric films with excellent mechanical properties for efficient and stable adsorption applications is reported. Non-solvent induced phase separation technology is developed to fabricate porous asymmetric poly(ether-block-amide) composite films. These films have a unique structure composed of a solid surface, a microporous surface, and hierarchical porous core, hence exhibiting prominent mechanical properties with an elongation at break up to 317% and mechanical resilience. Before and after 50-times cyclic stretching deformations, they still maintain intact porous structure, and their wetting angles of upper and lower surfaces to both water and cyclohexane are almost constant. Moreover, these films show excellent uptake for cyclohexane and water, and cyclic large deformations have little influence on the performance. It only takes 3 s to absorb 4 times of the weight of cyclohexane, while 1.8 times of water can be loaded within 134 s.

Synthesis and evaluation of novel fluorinated hematoporphyrin ether derivatives for photodynamic therapy

A photosensitizer with high phototoxicity, suitable amphipathy and low dark toxicity could play a pivotal role in photodynamic therapy (PDT). In this study, a facile and versatile approach was adopted to synthesize a series of novel fluorinated hematoporphyrin ether derivatives (I-1-I-5 and II1-II4), and the photodynamic activities of these compounds were studied. Compared to hematoporphyrin monomethyl ether (HMME), all PSs showed preferable photodynamic activity against A549 lung tumor cells. The longest visible absorption wavelength of these compounds was approximately 622 nm. Among them, II3 revealed the highest singlet oxygen yield (0.0957 min(-1)), the strongest phototoxicity (IC50 = 1.24 mu M), the lowest dark toxicity in vitro, and exhibited excellent anti-tumor effects in vivo. So compound II3 could act as new drug candidate for photodynamic therapy.

Inhalation bioaccessibility and health risk assessment of flame retardants in indoor dust from Vietnamese e-waste-dismantling workshops

Although bioaccessibility testing is appliedworldwide for appropriate chemical risk assessment, fewstudies have focused on the bioaccessibility of flame retardants (FRs), especially inhalation exposure. This study assessed inhalation exposure to FRs in indoor dust by workers at e-waste-dismantling workshops in northern Vietnam, by using modified simulated epithelial lung fluid (SELF) and artificial lysosomal fluid (ALF). The average mass concentrations of FRs were 130,000 ng/g for workplace dust (n = 3), 140,000 ng/g for floor dust (n = 3), and 74,000 ng/g for settled dust (n = 2), whereas the average bioaccessible concentrations of FRs were 1900, 1400, and 270 ng/g in the SELF condition and 2600, 770, and 490 ng/g in the ALF condition, respectively. Results clearly indicate that the bioaccessible concentrations of FRs are markedly lower than their mass concentrations. Tris(2- chloroethyl) phosphate (TCEP, similar to 19%), tris(2-chloroisopropyl) phosphate (TCIPP, similar to 35%), and tris(1,3-dichloroisopropyl) phosphate (TDCIPP, similar to 22%) showed comparably high bioaccessibility in both SELF and ALF conditions. In contrast, the bioaccessibility of tetrabromobisphenol A (TBBPA, similar to 20%) was high in the SELF condition, but not in the ALF condition. With regard to the test compounds’ physicochemical properties, the inhalation bioaccessibility of FRs in both conditions increased asmolecular weight or octanol-water partition coefficient decreased, and it decreased as water solubility decreased. Health risk assessment clearly indicated that the hazard quotient of FRs via inhalation exposure for workers in the e-waste-dismantling workshops was less than 1, suggesting that the inhalation exposure to FRs during indoor dismantling of e-waste at this site was negligible based on the current methodology of non-cancer health risk assessment used in this study.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 707-07-3, in my other articles.

Rapid, high-efficient and selective removal of cationic dyes from wastewater using hollow polydopamine microcapsules: Isotherm, kinetics, thermodynamics and mechanism

Developing new adsorbents with high adsorption capacity, rapid adsorption rate as well as good adsorption selectivity are highly demanded for efficiently purifying organic wastewater. We here reported new hollow polydopamine microcapsules (H-PDA-MCs) synthesized by a facile oxidation self-polymerization of dopamine using iron trioxide (Fe2O3) nano-cube as a template and considered as a high-efficiency adsorbent for capturing organic dyes. First, the morphology and microstructure of H-PDA-MCs were investigated through SEM, TEM, FTIR, XRD, N-2 adsorption and Zeta potential. The adsorption performance of H-PDA-MCs was systematically studied. Second, three kinetic models and five isothermal adsorption models were employed to study the adsorption process and the equilibrium adsorption behavior, respectively. Furthermore, the adsorption mechanism was discussed by FTIR, UV and XPS spectra. The results showed that H-PDA-MCs owned good selective adsorption behavior towards cationic dye. At 298.15 K, the maximum adsorption capacity of H-PDA-MCs towards MB was up to 191.55 mg g(-1) and the adsorption equilibrium time was only 60 min. The adsorption kinetic process was in line with the pseudo-second-order kinetic model, and the adsorption equilibrium data was well described by the Langmuir and Temkin isotherm models. The thermodynamic parameters demonstrated that the adsorption is an endothermic and spontaneous process.

Twist-Bend Nematic Glasses: The Synthesis and Characterisation of Pyrene-based Nonsymmetric Dimers

A selection of pyrene-based liquid crystal dimers have been prepared, containing either methylene-ether or diether linked spacers of varying length and parity. All the diether linked materials, CBOnO.Py (n=5, 6, 11, 12), exhibit conventional nematic and smectic A phases, with the exception of CBO11O.Py which is exclusively nematic. The methylene-ether linked dimer, CBnO.Py, with an even-membered spacer (n=5) was solely nematogenic, but odd-members (n=6, 8, 10) exhibited both nematic and twist-bend nematic phases. Replacement of the cyanobiphenyl fragment by cyanoterphenyl giving CT6O.Py, gave elevated melting and nematic-isotropic transition temperatures, and SmA and SmCA phases were observed on cooling the nematic phase. Intermolecular face-to-face associations of the pyrene moieties drive glass formation, and all these materials have a glass transition temperature at or above room temperature. The stability of the glassy twist-bend nematic phase allowed for its study using AFM, and the helical pitch length, P-TB, was measured as 6.3 and 6.7 nm for CB6O.Py and CB8O.Py, respectively. These values are comparable to the shortest pitch of a twist-bend nematic phase measured to date.
