Herein, the first example of rhodium-catalyzed dealkenylative arylation of alkenes with arylboronic compounds, thereby providing an unconventional access to biaryls with excellent chemoselectivity was diclosed. In this method, C(aryl)-C(alkenyl) and C(alkenyl)-C(alkenyl) bonds in various alkenes and 1,3-dienes could be cleaved via a hydrometalation and followed by β-carbon elimination pathway for Suzuki-Miyaura reactions. Furthermore, a series of novel organic fluorescent mols. with excellent photophys. properties were efficiently constructed with this protocol.

Hodgson, Ernest published the artcileDietary choline requirements, phospholipids, and development in Phormia regina, Name: 3-Carboxy-N,N,N-trimethylpropan-1-aminium chloride, the publication is Comparative Biochemistry and Physiology (1969), 29(1), 343-59, database is CAplus.

Twenty-six compounds were tested for their ability to support growth and development when fed, in lieu of choline, to P. regina. Sixteen supported larval growth and previous findings on structure-function relation in choline substitutes were confirmed. Only ten compounds permitted appreciable formation of puparia and only four of these permitted the emergence of normal adults. Thus, the structural requirements for postlarval development are much more rigorous than those for larval growth. No compound was as effective as choline. All compounds which support larval growth are incorporated into phospholipids analogous to phosphatidylcholine, indicating that the cytidine pathway for phospholipid synthesis is relatively nonspecific. Isopropylaminoethanol is a growth inhibitor when fed to P. regina larvae.

Church, J. S. published the artcileLanasol dyes and wool fibers. Part II: Model studies on the mechanism of dye fixation in an aqueous system, Synthetic Route of 18791-02-1, the publication is Dyes and Pigments (1998), 39(4), 313-333, database is CAplus.

The mechanism of the fixation of Lanasol dyes to the various amino acid side chain sites within wool protein was investigated using model compounds in a mixed solvent system. As the dyeing of wool is generally carried out in an aqueous system at the boil it was felt that the model system would be more accurate if the compounds studied were water soluble The synthesis of the sulfonated version of the model reactive dye compound used in Part I and its subsequent reaction with model wool compds is reported. In addition, a model compound based on benzenesulfonic acid, and an actual com. Lanasol dye were also reacted. The reaction products were isolated by chromatog. and then characterized by proton and carbon-13 NMR, and electrospray mass spectroscopy. In general the results were consistent with those obtained from the study carried out in the acetone/water solvent system. The dibromo form of the dye reactive group is only converted to the monobromo form in the presence of model wool compounds and both forms react with model wool compounds to yield the same products. Amines reacted with the model dyes to form a product containing an aziridine ring, but no evidence for the proposed reaction of this ring with a second nucleophilic wool site to form a crosslink between 2 protein chain segments could be detected. In the few cases where an aziridine ring structure was not formed, the products obtained were found to support a Michael addition (1,4-addition) reaction mechanism. Unlike the results found for the mixed solvent system, the wool models for N-terminal groups did not react with the model dye compounds

A site-selective defluorinative sp³ C-H alkylation of secondary amides that rapidly and reliably incorporates gem-difluoroalkene motifs into previously unfunctionalized sp³ sites was disclosed. This protocol was distinguished by its mild conditions, wide scope and exquisite site-selectivity, thus unlocking a new platform to introduce carbonyl isosteres at saturated hydrocarbon sites.

Fantacuzzi, Marialuigia published the artcileSynthesis, biological evaluation, and docking study of indole aryl sulfonamides as aromatase inhibitors, SDS of cas: 254749-11-6, the publication is European Journal of Medicinal Chemistry (2020), 111815, database is CAplus and MEDLINE.

In order to identify new aromatase enzyme inhibitors, thirty aryl sulfonamide derivatives containing an indole nucleus have been synthesized. The enzyme inhibition assay showed that four compounds inhibit aromatase in the sub-micromolar range. Loading concentrations of these four compounds were afterwards tested for cell viability and cytotoxicity on MCF7 human breast cancer cells, revealing a time- and dose-dependent decrease of active metabolizing cells over the time of the culture (0-72 h), starting from a concentration of 100μM. Likewise LDH released raised up to 40% at early time of exposures (24 h). Finally, the docking study showed that the best active compounds efficiently bound in the active site of the aromatase; high values of HBD and low levels of HBA are the principal requirement evidenced by the QSAR model.

Dimethylsulfoxonium methylide was treated with esters under mild conditions to rapidly afford the corresponding carboxylic acids at room temperature Moreover, by performing the procedure on enantiopure substrates, it was demonstrated that the reaction occurs without racemization. ¹⁸O-labeled reagents showed that the reaction does not proceed through an ester hydrolysis mechanism. The reactions are characterized by an unusual reactivity of the dimethylsulfoxonium methylide. This methodol. is general and can be considered a valid alternate route for ester cleavage when a substrate is sensitive to hydrolysis conditions.

Mol. recognition-driven self-assembly employing single-stranded DNA (ssDNA) as a template is a promising approach to access complex architectures from simple building blocks. Oligonucleotide-based nanotechnol. and soft-materials benefit from the high information storage d., self-correction, and memory function of DNA. Here we control these beneficial properties with light in a photoresponsive biohybrid hydrogel, adding an extra level of function to the system. An ssDNA template was combined with a complementary photo-responsive unit to reversibly switch between various functional states of the supramol. assembly using a combination of light and heat. We studied the structural response of the hydrogel at both the microscopic and macroscopic scale using a combination of UV-vis absorption and CD spectroscopy, as well as fluorescence, transmission electron, and at. force microscopy. The hydrogels grown from these supramol. self-assembly systems show remarkable shape-memory properties and imprinting shape-behavior while the macroscopic shape of the materials obtained can be further manipulated by irradiation
