The article was titled 《Synthesis and Structural Elucidation of Bisdibenzocorannulene in Multiple Redox States》.Reference of 3-Methoxyphenylboronic acid The article contains the following contents:

An anti-folded bowl-shaped bisdibenzocorannulene (BDBC) featuring a new chair-cyclohexane-like hexagon as a bridge of two dibenzocorannulene moieties was reported. The neutral compound showed multiple redox-active properties and could be converted to the corresponding redox states through chem. reduction or oxidation Chem. reduction of BDBC by stoichiometric addition of metallic potassium in the presence of [18]crown-6 ether, provided a radical anion BDBC.- and a dianion BDBC2-, resp.; while chem. oxidation by silver hexafluoroantimonate(V), converted the neutral compound to an open-shell singlet diradical dication (BDBC••)2+. The structural consequences of both electron-reduction and oxidation were closely related to the release of ring-strain of the bowl-shaped π-scaffold and imposed steric hindrance of the hexagonal bridge. In addition, the unusual open-shell nature of the dication could mainly be attributed to the changing of localized antiaromaticity in the closed-shell structure to delocalized character in the biradical, and thus the emergence of weakly bonded π-electrons.3-Methoxyphenylboronic acid(cas: 10365-98-7Reference of 3-Methoxyphenylboronic acid) was used in this study.

3-Methoxyphenylboronic acid(cas: 10365-98-7) belongs to boronic acids. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.Reference of 3-Methoxyphenylboronic acid

Two new Schiff bases I (R = Cl, OMe) derived from L-cysteine and substituted benzaldehyde were synthesized. DFT calculations were based on global chem. reactivity indexes calculated using the B3LYP/6-31G*, B3LYP/6-31G**, and B3LYP/6-31+G* theory levels. Exptl. and theor. obtained values for FT-IR and NMR (1H, 13C) of test compounds showed good agreement. The reactivity descriptors of B3LYP (E, EHOMO, ELUMO, dipole moment, Δε, μ, η, ω) were calculated to predict the stability of newly synthesized compounds The microbiol. activity of the compounds was tested on several Gram-pos. bacteria: Staphylococcus aureus, Bacillus subtilis, Clostridium sporogenes, Microccocus luteus and Microccocus flavus. The following Gram-neg. bacteria were used to test the compounds: Escherichia coli, Pseudomonas aeruginosa Proteus hauseri, Klebsiella pneumoniae, Salmonella enterica subsp. enterica serovar Enteritidis. Also, the activity on the following yeasts was examined: Candida albicans, Saccharomyces cerevisiae and fungal strain Aspergillus brasilliensis. The Schiff base with chlorine in the structure has the best antimicrobial action against all tested microorganisms. The selected quantum chem. descriptors calculated for both compounds have a close relationship with the antimicrobial activity.

A decade after the report of the first efficient perovskite-based solar cell, development of novel hole-transporting materials (HTMs) is still one of the main topics in this research field. Two of the main advance vectors of this topic lie in obtaining materials with enhanced hole-extracting capability and in easing their synthetic cost. The use of anthra[1,9-bc:5,10-b′c′]dithiophene (ADT) as a flat π-conjugated frame for bearing arylamine electroactive moieties allows obtaining two novel highly efficient HTMs from very cheap precursors. The solar cells fabricated making use of the mixed composition (FAPbI3)0.85(MAPbBr3)0.15 perovskite and the novel ADT-based HTMs show power conversion efficiencies up to 17.6% under 1 sun illumination compared to the 18.1% observed when using the benchmark compound 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (spiro-OMeTAD). Detailed d. functional theory calculations allow rationalization of the observed opto-electrochem. properties and predict a flat mol. structure with a low reorganization energy that supports the high conductivity measured for the best-performing HTM.

Reference of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamateIn 2015 ,《Protease-triggered siRNA delivery vehicles》 appeared in Journal of Controlled Release. The author of the article were Rozema, David B.; Blokhin, Andrei V.; Wakefield, Darren H.; Benson, Jonathan D.; Carlson, Jeffrey C.; Klein, Jason J.; Almeida, Lauren J.; Nicholas, Anthony L.; Hamilton, Holly L.; Chu, Qili; Hegge, Julia O.; Wong, So C.; Trubetskoy, Vladimir S.; Hagen, Collin M.; Kitas, Eric; Wolff, Jon A.; Lewis, David L.. The article conveys some information:

The safe and efficacious delivery of membrane impermeable therapeutics requires cytoplasmic access without the toxicity of nonspecific cytoplasmic membrane lysis. We have developed a mechanism for control of cytoplasmic release which utilizes endogenous proteases as a trigger and results in functional delivery of small interfering RNA (siRNA). The delivery approach is based on reversible inhibition of membrane disruptive polymers with protease-sensitive substrates. Proteolytic hydrolysis upon endocytosis restores the membrane destabilizing activity of the polymers thereby allowing cytoplasmic access of the co-delivered siRNA. Protease-sensitive polymer masking reagents derived from polyethylene glycol (PEG), which inhibit membrane interactions, and N-acetylgalactosamine, which targets asialoglycoprotein receptors on hepatocytes, were synthesized and used to formulate masked polymer-siRNA delivery vehicles. The size, charge and stability of the vehicles enable functional delivery of siRNA after s.c. administration and, with modification of the targeting ligand, have the potential for extrahepatic targeting. The results came from multiple reactions, including the reaction of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Reference of tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate)

SDS of cas: 106685-40-9In 2020 ,《Ion Pair Strategy in Solid Lipid Nanoparticles: a Targeted Approach to Improve Epidermal Targeting with Controlled Adapalene Release, Resulting Reduced Skin Irritation》 was published in Pharmaceutical Research. The article was written by Rodrigues, Linna B. O.; Lima, Flavia A.; Alves, Camila P. B.; Martins-Santos, Elisangela; Aguiar, Marta M. G.; Oliveira, Cleida A.; Orefice, Rodrigo L.; Ferreira, Lucas A. M.; Goulart, Gisele A. C.. The article contains the following contents:

Abstract: Purpose: Adapalene (AD) is one of the main retinoids used in the topical therapy of acne, an extremely common skin disease usually associated with psychol. morbidity. However, like other retinoids, AD is frequently associated with skin irritation. To overcome the skin irritation, we proposed the encapsulation of AD in solid lipid nanoparticles (SLNs) using the ion pair strategy. Methods: The developed SLN-AD was characterized by high-performance liquid chromatog., differential scanning calorimetry, X-ray diffraction, synchrotron small-angle X-ray scattering, and transmission electron microscopy. In vitro permeation tests using porcine skin and in vivo mice skin irritation test were performed to evaluate, resp., the drug’s skin distribution and the skin irritation. Results: The characterization studies were able to demonstrate that the proposed strategy effectively provided high AD encapsulation in SLNs and its incorporation into a hydrophilic gel. Sustained release, epidermal targeting, and less skin irritation were observed for SLN-AD gel in comparison to the marketed AD gel. Conclusions: The studies demonstrated that the encapsulation of AD in SLNs through the formation of an ion pair is a valuable alternative to diminish the adverse skin reactions caused by AD and can optimize patient adherence to treatment.
