Ruffell, Katie published the artcileBismuth-Mediated α-Arylation of Acidic Diketones with ortho-Substituted Boronic Acids, Product Details of C7H8BClO2, the publication is Angewandte Chemie, International Edition (2022), 61(40), e202210840, database is CAplus and MEDLINE.

The Bi-mediated oxidative coupling of acidic diones and ortho-substituted arylboronic acids was reported. Starting from a bench-stable bismacycle precursor, a sequence of B-to-Bi transmetallation, oxidation and C-C bond formation furnished the arylated diones. Development of methodol. that tolerates both sensitive functionality and steric demand was supported by interrogation of key reactive intermediates. Application of this strategy to cyclic diones enables the concise synthesis of important agrochem. intermediates which were previously prepared using toxic Pb reagents. This methodol. also enabled the first ever arylation of fluoroalkyl diones which, upon condensation with hydrazine, providesd direct access to valuable fluoroalkyl pyrazoles.

Wesenhagen, Philana published the artcilePhotochromism and Electrochemistry of a Dithienylcyclopentene Electroactive Polymer, SDS of cas: 219537-97-0, the publication is Langmuir (2008), 24(12), 6334-6342, database is CAplus and MEDLINE.

A bifunctional substituted dithienylcyclopentene photochromic switch bearing electropolymerisable methoxystyryl units, which enable immobilization of the photochromic unit on conducting substrates, is reported. The spectroscopic, electrochem., and photochem. properties of a monomer in solution are compared with those of the polymer formed through oxidative electropolymerization The electroactive polymer films prepared on Au, Pt, glassy C, and In Ti oxide (ITO) electrodes were characterized by cyclic voltammetry, XPS, and at. force microscopy (AFM). The thickness of the films formed is limited to several monolayer equivalent The photochromic properties and stability of the polymer films were studied by UV/visible spectroscopy, electrochem., and XPS. Although the films are electrochem. and photochem. stable, their mech. stability with respect to adhesion to the electrode is sensitive to both the solvent and the electrode material employed, with more apolar solvents, glassy C, and ITO electrodes providing good adhesion of the polymer film. The polymer film is formed consistently as a thin film and can be switched both optically and electrochem. between the open and closed state of the photochromic dithienylethene moiety.

van Herpt, Jochem T. published the artcileLight-Controlled Formation of Vesicles and Supramolecular Organogels by a Cholesterol-Bearing Amphiphilic Molecular Switch, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Chemistry – A European Journal (2014), 20(6), 1737-1742, database is CAplus and MEDLINE.

A new responsive material composed of an amphiphilic light-switchable dithienyl ethene unit functionalized with a hydrophobic cholesterol unit and a hydrophilic poly(ethylene glycol)-modified pyridinium group has been designed. This unique single-mol. system shows responsive light-switchable self-assembly in both water and organic solvents. Light-triggered reversible vesicle formation in aqueous solutions is reported. The mol. shows a different behavior in apolar aromatic solvents, in which light-controlled formation of organogel fibers is observed The light-triggered aggregation behavior of this mol. demonstrates that control of a supramol. structure with light can be achieved in both aqueous and organic media and that this ability can be present in a single mol. This opens the way toward the effective development of new strategies in soft nanotechnol. for applications in controlled chem. release systems.

Harvey, Emma C. published the artcileIncorporating cobalt carbonyl moieties onto ethynylthiophene-based dithienylcyclopentene switches. 1. Photochemistry, Formula: C15H14Cl2S2, the publication is Organometallics (2014), 33(2), 447-456, database is CAplus.

Dithienylcyclopentenes I [X = H, F; Y = bond: 1o, M = void; 3o, M = Co₂(CO)₆; 5o, M = Co₂(CO)₄(dppm); Y = 1,4-C₆H₄: 2, M = void; 4, M = Co₂(CO)₆; 6, M = Co₂(CO)₄(dppm)] undergo photochem. conrotatory cyclization, giving the corresponding complexes II [1-C_s – 6-C_s] thus exhibiting photochromic switching properties. The synthesis and characterization of a series of dithienyl perhydro- and perfluorocyclopentene photochromic mol. switches 1o–6o appended with cobalt carbonyl binding 3-ethynylthiophene and phenyl-3-ethynylthiophene substituents are reported. Their photochromic properties, fatigue resistance, and thermal stability were examined to establish the effect of substituents on their performance as mol. photoswitches. The photochem. properties of the dithienylethene core were retained to the greatest extent by the inclusion of Ph units and a hexafluorocyclopentene ring. The alkyne units of the switches were used to coordinate cobalt carbonyl moieties: i.e., Co₂(CO)₆ and Co₂(CO)₄(dppm). The cobalt carbonyl moieties were found to reduce the efficiency of cyclization and cycloreversion of the dithienylethene unit. D. functional theory was used to identify the excited states responsible for cyclization.

Abd El-Karim, Somaia S. published the artcileRational design and synthesis of new tetralin-sulfonamide derivatives as potent anti-diabetics and DPP-4 inhibitors: 2D & 3D QSAR, in vivo radiolabeling and biodistribution studies, Recommanded Product: 5,6,7,8-Tetrahydronaphthalene-2-sulfonyl chloride, the publication is Bioorganic Chemistry (2018), 481-493, database is CAplus and MEDLINE.

Type 2 diabetes (T2D) is a severe disease and it is one of the most raising problems worldwide. This study deals with design, synthesis and in vivo determination of a new set of tetralin-sulfonamide derivatives as anti-diabetic and dipeptidyl peptidase-IV (DPP-4) inhibiting agents. Most of the new compounds exhibited significant hypoglycemic effect alongside with DPP-4 suppression potency considering sitagliptin as a reference drug. The most promising compounds 4, 15 showed 2.80 nM DPP-4 IC₅₀ with 20-40 folds selectivity over DPP-8 and DPP-9. 2D and 3D QSAR models were performed using auto QSAR of Schrodinger, QuaSAR of MOE and 3D Field-based QSAR of Schrodinger, resp. The exptl. results revealed that the alignment-independent descriptors, electrostatic and steric field descriptors were significantly correlated with the antidiabetic activity of the new derivatives In addition, the new compounds were docked in the active site of DPP-4 in reference to sitagliptin to rationalize the binding modes of the compounds with the amino acid residues of the enzyme. Furthermore, ¹³¹I-compound 4 complex was selected to evaluate the pharmacokinetic behavioral profile of compound 4 and its body organs uptakes alongside its elimination pathway as a representative example for the rest of the analogs. The bio distribution pattern of the tracer proved the selective accumulation of ¹³¹I-substrate in the pancreas and rapid clearance from most of the body organs.

A heterogeneous transition metal-free material, a type of carbon nitride photocatalyst, potassium poly(heptazine imide), was employed to produce sulfonyl chlorides from arenediazonium salts under mild conditions (visible light irradiation, room temperature) with 50-95% yields. The method was suitable for the synthesis of both electron rich and electron deficient compounds and it showed high tolerance toward different functional groups (halides, ester, nitro, cyano groups). Thus, a sustainable photocatalytic alternative to the Meerwein chlorosulfonylation reaction was offered.

Sui, Yan-Fei published the artcilePyrimidinetrione-imidazoles as a Unique Structural Type of Potential Agents towards Candida Albicans: Design, Synthesis and Biological Evaluation, Name: 3-Chlorobenzylchloride, the publication is Chemistry – An Asian Journal (2021), 16(11), 1417-1429, database is CAplus and MEDLINE.

A series of pyrimidinetrione-imidazole conjugates I [R¹ = H, Et, 2-chlorobenzl, etc.] as potentially antifungal agents were developed. Bioassays manifested that I [R¹ = 4-fluorobenzl] exerted favorable inhibition towards C. albicans (MIC=0.002 mM), being 6.5 folds more active than clin. antifungal drug fluconazole (MIC=0.013 mM). Preliminary mechanism research indicated that compound I [R¹ = 4-fluorobenzl] could not only depolarize membrane potential but also permeabilize the membrane of C. albicans. Mol. docking was operated to simulate the interaction mode between mol. I [R¹ = 4-fluorobenzl] and CYP51. In addition, hybrid I [R¹ = 4-fluorobenzl] might form I [R¹ = 4-fluorobenzl]-DNA supramol. complex via intercalating into DNA. The interference of membrane and DNA might contributed to its fungicidal capacity with no obvious tendency to induce the resistance against C. albicans. Conjugate I [R¹ = 4-fluorobenzl] endowed good blood compatibility as well as low cytotoxicity towards HeLa and HEK-293T cells.

Cozzi, Franco published the artcileThrough-space interactions between parallel-offset arenes at the van der Waals distance: 1,8-diarylbiphenylene syntheses, structure and QM computations, SDS of cas: 209919-30-2, the publication is Physical Chemistry Chemical Physics (2008), 10(19), 2686-2694, database is CAplus and MEDLINE.

A model for studying polar-π interactions between arenes spaced at van der Waals distances is developed on the basis of peri-diarylbiphenylenes. A set of 1,8-diarylbiphenylenes is synthesized comprising two Hammett series, one with reference to mesityl ring interactions and the other with reference to pentafluorophenyl ring interactions. X-Ray crystal structures of several derivatives are determined Barriers to rotation of the probe aryl ring are derived from dynamic NMR data and show a trend for the mesityl reference series (ΔG^≠vs. σ°). The model is also used as a test for comparison of modern d. functional methods, including B3LYP, M06-2X and BMK functionals; dispersive effects are seen to be an important factor in the proper theor. treatment of arene interactions.
