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.

Yue, Wen-Jun published the artcileSite-Selective Defluorinative sp³ C-H Alkylation of Secondary Amides, Synthetic Route of 864725-22-4, the publication is Journal of the American Chemical Society (2021), 143(17), 6395-6400, database is CAplus and MEDLINE.

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.

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

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.

Tan, Guangying published the artcileRhodium-Catalyzed Dealkenylative Arylation of Alkenes with Arylboronic Compounds, SDS of cas: 145349-62-8, the publication is Angewandte Chemie, International Edition (2021), 60(28), 15650-15655, database is CAplus and MEDLINE.

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.

Buendia, Julien published the artcileTandem catalytic C(sp³)-H amination/sila-Sonogashira-Hagihara coupling reactions with iodine reagents, HPLC of Formula: 866-23-9, the publication is Angewandte Chemie, International Edition (2015), 54(19), 5697-5701, database is CAplus and MEDLINE.

A new tandem C-N and C-C bond-forming reaction has been achieved through Rh^II/Pd⁰ catalysis. The sequence combines a catalytic C(sp³)-H nitrene insertion with a palladium-catalyzed C-C cross-coupling to afford complex nitrogenous mols., e.g., I, with very good yields and complete stereoselectivity. The sequence first involves an iodine(III) oxidant, then the in situ generated iodine(I) byproduct is used as a coupling partner. The synthetic value of iodoarenes produced in trivalent iodine reagent mediated oxidations has been demonstrated.

Half-sandwich rhodium(III) and ruthenium(II) complexes bearing a new redox-active ferrocenyl NHC-thioether ligand have been prepared The synthesis of ferrocenyl thioether-imidazolium salts was carried out via intermediate FcSCH₂CH₂Cl using an improved procedure. Rhodium(III) complex and ruthenium(II) complex were obtained in good yields and were fully characterised by NMR spectroscopy, x-ray diffraction anal. and electrochem. Rhodium(III) complex shows a complex ABCD system by ¹H NMR, which denotes conformational rigidity due to the presence of several bulky groups. Electrochem. anal. by cyclic voltammetry reveals reversible redox behavior about the iron center in both complexes, and indicates electronic communication between iron and rhodium or ruthenium.
