A five-membered aromatic ring containing at least one nitrogen atom, forming the basis for important antifungal and antimicrobial drugs like fluconazole.
From 'azo-' (nitrogen) + '-ole' (chemical suffix for unsaturated rings). Developed in 1950s organic chemistry as researchers synthesized rings with nitrogens in new positions.
Azoles are some of the most successful drug blueprints ever made—the basic ring structure gets small modifications to create medicines that fight fungal infections from athlete's foot to serious lung diseases.
