Activity Profiling of Nitro‐Substituted Di(Hetero)Aryl 1,3,4‐ and 1,2,4‐Oxadiazoles: Antimicrobial, Cholinesterase Inhibition and Antioxidant Potential

Archiv der Pharmazie, Volume 359, Issue 1, January 2026.
Novel nitro‐substituted diaryl 1,3,4‐ and 1,2,4‐oxadiazoles were synthesised via molecular hybridisation of bioactive heterocycles. Selected derivatives exhibited potent antimicrobial activity, including against Mycobacterium tuberculosis and Staphylococcus aureus, and cholinesterase inhibitory activity, with promising selectivity.
