Interferon-induced transmembrane protein 3 (IFITM3) is an antiviral transmembrane protein that is thought to serve as the primary factor for inhibiting the replication of a large number of viruses, including West Nile virus, Dengue virus, Ebola virus, and Zika virus. Production of this 14.5 kDa, 133-residue transmembrane protein, especially with essential posttranslational modifications, by recombinant expression is challenging. In this report, we document the chemical synthesis of IFTIM3 in multi-milligram quantities (>15 mg) and the preparation of phosphorylated and fluorescent variants. The synthesis was accomplished by using KAHA ligations, which operate under acidic aqueous/organic mixtures that excel at solubilizing even the exceptionally hydrophobic C-terminal region of IFITM3. The synthetic material is readily incorporated into model vesicles and forms the basis for using synthetic, homogenous IFITM3 and its derivatives for further studying its structure and biological mode of action.

Herin, the successful synthesis of a bis Schiff base (L) has been achieved using 2-hydroxy-1-naphthaldehyde and 1,3-diaminoguanidine as raw materials, which was further characterized by infrared spectroscopy, mass spectrometry, and nuclear magnetic resonance hydrogen spectrum. Moreover, spectroscopic experiments demonstrated that the probe L showed good selectivity and visual detectability for Al. Its detection limit (DL) is 2.

The selective oxyfunctionalization of unsaturated fatty acids is difficult in chemical reactions, whereas regio- and stereoselective oxyfunctionalization is often performed in biocatalytic synthesis. Fatty acid oxygenases, including hydratases, lipoxygenases, dioxygenases, diol synthases, cytochrome P450 monooxygenases, peroxygenases, and 12-hydroxylases, are used to convert C16 and C18 unsaturated fatty acids to diverse regio- and stereoselective mono-, di-, and trihydroxy fatty acids via selective oxyfunctionalization. The formed hydroxy fatty acids or hydroperoxy fatty acids are metabolized to industrially important oxygenated chemicals such as lactones, green leaf volatiles, and bioplastic monomers, including ω-hydroxy fatty acids, α,ω-dicarboxylic acids, and fatty alcohols, by biocatalysts.

This study presents an eco-friendly, cost-effective approach for synthesizing highly efficient nanocatalysts with the help of organic waste. Iron nanoparticles (INPs) were synthesized from aqueous extracts of potato, potato peel, and potato leaf and were evaluated for their photocatalytic efficiency for the degradation of methylene blue dye. X-ray Diffraction (XRD) confirmed FeO nanoparticles cubic crystal structure with the smallest crystallite size (9.
