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.

Article Synopsis
  • The study investigates the effects of kinetin and gibberellic acid (GA3) on faba bean plants subjected to chromium (Cr) stress, which negatively impacts their growth and physiological functions.
  • Chromium exposure led to reduced growth, impaired photosynthesis, and increased harmful compounds like malondialdehyde and hydrogen peroxide in the plants.
  • The application of kinetin and GA3 improved growth and photosynthesis, upregulated antioxidant systems, enhanced protective compounds, and decreased chromium uptake, effectively mitigating the stress on faba beans.

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.
