4g) and isoxazolines (5a-strong class="EmphasisTypeBold">5g) have been synthesized in good-to-excellent yield from the corresponding chalcones (3a-strong class="EmphasisTypeBold">3g) under ultrasound irradiation. The newly synthesized compounds were characterized and screened for their in vitro antimicrobial activity against different bacterial and fungal strains by standard agar dilution method and in vitro antioxidant activity by using DPPH method. Some of the synthesized compounds displayed significant antimicrobial and antioxidant activity. Docking study of the synthesized compounds has been performed, and results showed good binding mode in the active site of fungal enzyme P450 cytochrome lanosterol 14 α-demethylase. ADMET properties of synthesized compounds showed good drug-like properties." />
