Enhanced photocatalytic degradation of crystal violet dye and high-performance electrochemical supercapacitor applications of hydrothermally synthesised magnetic bifunctional nanocomposite (FeO/ZnO).

The present investigation employed a facile hydrothermal approach for the fabrication of FeO/ZnO dual-functional magnetic nanocomposite. Supercapacitor and visible-light-driven photocatalytic applications of the material were explored. X-ray diffraction, Fourier transform infrared spectra, ultraviolet-visible diffuse reflectance spectra (UV-vis/DRS), field emission scanning electron microscopy (FE-SEM), energy dispersive x-ray spectroscopy, and vibrating sample magnetometer were used to analyse the nanocomposite's structural, morphological, optical, and magnetic properties.

Palladium catalyzed migratory heck coupling of arteannuin B and boronic acids: An approach towards the synthesis of antiproliferative agents in breast and lung cancer cells.

We have recently highlighting the role of spiroisoxazoline arteannuin B derivatives in mediating proinflammatory cytokines like IL-6, TNfα and NO in vitro. In the present study, a series of new β-arylated arteannuin B analogues were synthesized through coupling with arylboroic acids and evaluated for their in vitro cytotoxic activity in a panel of six cancer cell lines. The binding efficiency was verified by docking of the original ligand within the active site of ATPase domain of GRP78 (PDB ID: 3LDL) at a resolution of 2.

Biomimetic Domino Knoevenagel/Cycloisomerization Strategy for the Synthesis of Citridone A and Derivatives.

Studies on Knoevenagel condensations between conjugated dienals and 4-hydroxy-2-pyridone/quinolone-type 1,3-dicarbonyl equivalents led to the development of a simple one-pot strategy to access citridone A and related synthetic cyclopenta[]furopyridones/quinolones. The present work highlights the power of domino cascades in the synthesis of natural product frameworks and may help promote future studies on this promising new class of pyridone alkaloids.

Tandem Carbenoid C-H Functionalization/Conia-ene Cyclization of -Propargyl Indoles Generates Pyrroloindoles under Cooperative Rh(II)/Zn(II) Catalysis.

The decomposition of diazodicarbonyl compounds in the presence of various metal catalysts has become a reliable method for the functionalization of indoles via carbenoid intermediates. Exploiting the nucleophilic reactivity of the in situ generated malonic ester product formed, we herein report a tandem C-H functionalization/Conia-ene cyclization of -alkyne tethered indoles. This double functionalization of diazodicarbonyls generates a range of pyrrolo[1,2-]-, pyrido[1,2-]-, and azepino[1,2-]indole products with good synthetic efficiency.
