Yang, Ting published the artcileDiscovery of Tertiary Amine and Indole Derivatives as Potent RORγt Inverse Agonists, Name: 1-(2-Bromoethyl)-3-(trifluoromethyl)benzene, the publication is ACS Medicinal Chemistry Letters (2014), 5(1), 65-68, database is CAplus and MEDLINE.

A novel series of tertiary amines as retinoid-related orphan receptor gamma-t (RORγt) inverse agonists was discovered through agonist/inverse agonist conversion. The level of RORγt inhibition can be enhanced by modulating the conformational disruption of H12 in RORγt LBD. Linker exploration and rational design led to the discovery of more potent indole-based RORγt inverse agonists, e.g., I.

Chen, Wen-Bin published the artcileSynthesis and screening of novel inositol phosphonate derivatives for anticancer functions in vitro, Synthetic Route of 66197-72-6, the publication is Chinese Chemical Letters (2015), 26(3), 329-333, database is CAplus.

Phosphonates have been frequently used as suitable isosteric and isoelectronic replacements for biol. important phosphates in the development of drugs or drug candidates because of their stability toward the action of phosphatases and other enzymes. In this paper, 12 mono-phosphonate inositol compounds, e.g. I, were prepared with phosphonate instead of phosphate by two kinds of strategies, nucleophilic substitution and Arbuzov rearrangement, resp. All compounds were evaluated in vitro for their activity against non-small cell lung cancer (NSCLC) cell line A549. I exhibited good antitumor activity at 10 μg/mL.

Tsai, Yu-Tang published the artcileFrequency-Selective Photobleaching as a Route to Chromatic Control in Supramolecular OLED Devices, Recommanded Product: 2,5-Dibromo-3,4-dinitrothiophene, the publication is ACS Applied Materials & Interfaces (2017), 9(41), 36045-36052, database is CAplus and MEDLINE.

Mols. that spontaneously self-organize into small electroluminescent domains of sub-μm dimensions when dissolved in THF are reported. The self-assembled spherical aggregates have an average diameter of 300 nm and exhibit efficient energy transfer from the blue to the green or red component. The aggregates can be chromatically addressed or patterned by selective bleaching of the energy-acceptor component using a laser source. This allows the fabrication of electroluminescence devices by directly photopatterning the active layer without the need of addnl. steps. Sub-μm features (700 nm) can be achieved using a collimated light source.

Lv, You published the artcileDiscovery of Novel 3,4-Dichloroisothiazole-Containing Coumarins as Fungicidal Leads, Quality Control of 401-55-8, the publication is Journal of Agricultural and Food Chemistry (2021), 69(14), 4253-4262, database is CAplus and MEDLINE.

Natural products are one of the resources for discovering novel fungicidal leads. As a natural fungicide, osthole was used as a coumarin-based lead compound for the development of novel fungicides. Here, a series of 3,4-dichloroisothiazole-containing 7-hydroxycoumarins were rationally designed, synthesized, and characterized by introducing a bioactive substructure, 3,4-dichloroisothiazole, into the coumarin skeleton. In vitro bioassay indicated that compound (I) displayed good activity against Rhizoctonia solani, Physalospora piricola, Sclerotinia sclerotiorum, and Botrytis cinerea. Its median effective concentration (EC₅₀) value against each of these fungi fell between 0.88 and 2.50μg/mL, which was much lower than that of osthole against the corresponding pathogen (between 7.38 and 74.59μg/mL). In vivo screening validated that (II) exhibited 100%, 60%, and 20% efficacy against R. solani at 200, 100, and 50μg/mL, resp. RNA sequence anal. implied that growth inhibition of R. solani by II might result from potential disruptions of fungal membrane formation and intracellular metabolism Furthermore, a field experiment with cucumber plants indicated that (III) showed 62.73% and 74.03% efficacy against Pseudoperonospora cubensis (Berk. & Curt.) Rostov. at rates of 12.5 g a.i./ha and 25 g a.i./ha, resp., which showed no significant difference between III and osthole at 30 g a.i./ha. Our studies suggested that III, I, and II might be used as fungicidal leads for further optimization.

Li, Yan published the artcileLigand-Controlled Cobalt-Catalyzed Regiodivergent Alkyne Hydroalkylation, Recommanded Product: Cobalt(II) dibromo(1,2-dimethoxyethane), the publication is Journal of the American Chemical Society (2022), 144(30), 13961-13972, database is CAplus and MEDLINE.

Herein, a ligand-controlled cobalt-catalyzed regiodivergent alkyne hydroalkylation was reported. The sensible selection of bisoxazoline and pyridine-oxazoline ligands led to reliable and predictable protocols that provided (E)-1,2-disubstituted and 1,1-disubstituted alkenes with high E/Z stereoselectivity and regioisomeric ratio starting from identical terminal alkyne and alkyl halide substrates and produced trisubstituted alkenes in the case of internal alkynes. This method exhibited a broad scope for terminal and internal alkynes with a wide range of activated and unactivated alkyl halides and shows excellent functional group compatibility.

Li, Hao-Chun published the artcileColor tuning and highly efficient blue emitters of finite diphenylamino-containing oligo(arylenevinylene) derivatives using fluoro substituents, Recommanded Product: 4-Bromo-1-(bromomethyl)-2-fluorobenzene, the publication is Advanced Functional Materials (2007), 17(4), 520-530, database is CAplus.

New fluoro derivatives of Ph₂N-containing (Ph: phenyl) oligo(arylenevinylene) derivatives were prepared by using double Heck-coupling reactions or Horner-Wadsworth-Emmons reactions. These oligomers are highly fluorescent (fluorescence quantum yields Φ = 0.93-0.68) with emissions in a broad wavelength region (448-579 nm), depending on the position of the fluoro substituents. The highest occupied and LUMO (HOMO-LUMO) energy levels of these oligomers were characterized by electrochem. and UV spectroscopy. The effects of the fluoro substituents on the energy levels are rationalized with HOMO-LUMO simulations. In a classical organic light emitting diode (OLED), one representative (5a) shows a remarkable external quantum efficiency value (η_ext = 4.87 %) at J = 20 mA cm^-2; the maximum brightness at 10.2 V is 22,506 cd m^-2 (λ = 458 nm; Commission Internationale de l’Eclairage (CIE) coordinates x = 0.14, y = 0.14) with a full width at half-maximum of 54 nm, demonstrating the superiority of these fluoro-containing oligomers in OLED devices.

A nickel-catalyzed reductive cross-coupling reaction of aryl cyclopropyl ketones with easily accessible unactivated alkyl bromides to access aryl alkyl ketones was developed. This strategy facilitated access to various of γ-alkyl substituted ketones via ring opening of cyclopropyl ketones (26 examples, 50-90% yield). Initial mechanistic studies revealed that the reaction proceeds via a radical cleavage of the alkyl bromide.

This work reported two novel liquid crystals with good fluorescence in aggregated states. Two tetraphenylethylene-rufigallol-tetraphenylethylene trimers were prepared in simple procedure. The columnar liquid crystalline behaviors of compound I [R = pentyl, dodecyl] were confirmed by the anal. of differential scanning calorimetry, polarizing optical microscopy and X-ray diffraction. Compound I [R = dodecyl] exhibited an ordered hexagonal columnar mesophase. They possessed excellent AIE fluorescence properties in THF-H₂O solution, solid film and mesophase. The fluorescence quantum yields of compounds I were 12% and 22% in solid films, 14% and 24% in mesophase, resp.
