Synthesis of novel benzopyrimido[4,5-]azoninone analogs catalyzed by biosynthesized Ag-TiO core/shell magnetic nanocatalyst and assessment of their antioxidant activity.

The present work reported the synthesis of novel benzopyrimido[4,5-]azoninone analogs using a biosynthesized Ag-TiO core/shell magnetic nanocatalyst. Accordingly, three-component one-pot reactions of benzoazonine-dione with thiourea and aryl aldehyde derivatives under nanocatalytic and optimized conditions afforded reasonable to brilliant yields of the target products (57-91%). The nanocatalyst was synthesized by a facile method using turmeric ethanol extract as a reducing and chelating agent.

Silicon Nanoparticle-Induced Regulation of Carbohydrate Metabolism, Photosynthesis, and ROS Homeostasis in Subjected to Salinity Stress.

Agricultural crops are facing major restraints with the rapid augmentation of global warming, salt being a major factor affecting productivity. Tomato () plant has immense nutritional significance; however, it can be negatively influenced by salinity stress. Nanoparticles (NPs) have excellent properties, due to which these particles are used in agriculture to enhance various growth parameters even in the presence of abiotic stresses.
