《Development and Investigation of Vitamin C-Enriched Adapalene-Loaded Transfersome Gel: a Collegial Approach for the Treatment of Acne Vulgaris》 was written by Vasanth, Sandhya; Dubey, Akhilesh; Ravi, G. S.; Lewis, Shaila A.; Ghate, Vivek M.; El-Zahaby, Sally A.; Hebbar, Srinivas. Application In Synthesis of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acidThis research focused onvitamin C adapalene transfersome gel delivery acne vulgaris; Transfersomes; adapalene; cosmetics; topical; vitamin C. The article conveys some information:

Adapalene-loaded transfersome gel containing vitamin C as a combination therapy for the management of acne vulgaris was developed in the present study. The transfersome was prepared by reverse-phase evaporation, and the effect of various process parameters were investigated by the Design of Experiment (DOE) approach and optimized based on the particle size (PS), polydispersity index (PDI), zeta potential (ZP), and entrapment efficiency (EE). The selected tranfersomes were further evaluated for their thermal behavior and morphol. by transmission electron microscopy and turbidity measurements and incorporated into a gel with/without vitamin C. The gel was evaluated and compared with the marketed product (Adiff gel) for various physicochem. parameters, and in vivo studies in testosterone-induced rat models of acne. The prepared transfersomes had PS in the range of 280 to 400 nm, PDI values of 0.416 to 0.8, ZP of – 38 to – 20 mV, and % EE of 32 to 70%. DSC studies confirmed a pos. interaction of the components in the transfersome. Surface morphol. confirmed that the vesicles were spherical, unilamellar, and discrete. A relative deformability study showed higher elasticity of the transfersomes compared with Adiff aqs gel. Ascorbyl-6-palmitate in adapalene-loaded transfersome gel containing vitamin C (ADVTG) was found to have a good antioxidant free radical-scavenging activity. An in vitro drug release study showed that the sustained release of the transfersomal formulations was attributed to the flexibility of the vesicles by which penetration was increased. ADVTG was found to be promising in treating acne compared with the marketed product. The experimental part of the paper was very detailed, including the reaction process of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid(cas: 106685-40-9Application In Synthesis of 6-(3-(Adamantan-1-yl)-4-methoxyphenyl)-2-naphthoic acid)

Computed Properties of C12H10O2On November 5, 2021 ,《Effects of side alkoxy groups on the arylacetylene unit on properties of Poly(silylene arylacetylene)s》 appeared in European Polymer Journal. The author of the article were Li, Jixian; Gong, Changjun; Lv, Shuaikang; Huang, Farong. The article conveys some information:

A series of poly(dimethylsilylene arylacetylene)s with different side alkoxy groups on the arylacetylene unit (named as PSA-(AO) resins), including methoxy (MO), ethoxy (EO), pentyloxy (PO), and decyloxy (DO), were synthesized from corresponding disubstituted diethynylbenzene and dichlorodimethylsilane. The processability, heat resistance and mech. properties, and the effects of side alkoxy groups were investigated. The results show the processability of PSA-(AO) resins is improved, while the flexural properties and heat resistance of the relative cured resins decrease with the increase in the length of side alkoxy groups. The flexural strength and degradation temperature of 5% weight loss for the cured PSA-(EO) resin with side ethoxy groups reach 20.8 MPa and 415°, resp. In the experiment, the researchers used 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Computed Properties of C12H10O2)

Category: ethers-buliding-blocksOn March 31, 2020, Albano, Gianluigi; Colli, Tony; Nucci, Luigi; Charaf, Rima; Biver, Tarita; Pucci, Andrea; Aronica, Laura Antonella published an article in Dyes and Pigments. The article was 《Synthesis of new bis[1-(thiophenyl)propynones] as potential organic dyes for colorless luminescent solar concentrators (LSCs)》. The article mentions the following:

New luminophores having different aryl nuclei and propynones moieties have been obtained via Sonogashira reactions. Their optical properties were evaluated and indicated that carbonyl groups are responsible for significant bathochromic effects and high Stokes shifts. The insertion of -OMe groups on the central benzene unit gives to the fluorophore high optical efficiency (7.7%) when homogeneously dispersed in a poly(cyclohexyl methacrylate) (PCMA) film and connected to a PV cell. In the experiment, the researchers used many compounds, for example, 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Category: ethers-buliding-blocks)

1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Ethers do have nonbonding electron pairs on their oxygen atoms, and they can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. Category: ethers-buliding-blocks The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.

The information in the text is summarized as follows:

Novel oligo- and polyenaminones with Mw-3000 Da were prepared in excellent yields by amino-enaminone ‘click’ polymerization of 1,3- and 1,4-bis[3-(dimethylamino)acryloyl]arenes with 1,3- and 1,4-phenylenediamine. The obtained oligomers and polymers were depolymerized quant. to the starting bis-enaminones and diamines by treatment with excess dimethylamine in ethanol at 50°C. This simple polymerization/depolymerization method allows for a closed-loop recycling of polyenaminone-based materials. UV light absorbance at wavelengths below 470 nm indicates promising optical properties of these polymers.

And the article was published in Chemistry – An Asian Journal in 2019. Safety of Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

Two bis(triarylamine) diradical dication salts 12+2[Al(ORF)4]- and 22+2[Al(ORF)4]- bridged with an orthogonal oriented bisanthrancene motif were synthesized. Their solid state and electronic structures were studied by various exptl. approaches in conjunction with theor. calculations Superconducting quantum interference device measurements and d. functional theory calculations reveal that both of 12+ and 22+ feature open-shell singlet ground states with rather small singlet-triplet energy gaps; thus, they can be regarded as nearly pure diradicals (biradicals). Their diradical characters are enhanced by the orthogonal configuration of the bisanthrancene moiety which demonstrates the importance of the geometry of bridging units in turning the electronic structures of bis(triarylamine) dications.

These research results belong to Zhang, Jian; Wang, Yi-Yan; Sun, He; Li, Shao-Yu; Xiang, Shao-Hua; Tan, Bin. Safety of 2-(Benzyloxy)acetaldehyde The article mentions the following:

A catalytic enantioselective three-component Ugi reaction was developed. SPINOL-derived phosphoric acid with bulky 2,4,6-tricyclohexylphenyl groups at the 6,6′ positions I was found to be the best catalyst to afford α-amino amide derivatives, e.g., II in good to excellent yields (62% to 99%) and enantiocontrol (81% to >99% enantiomeric excess). This asym. reaction was applicable well to an array of aliphatic aldehydes.
