     Any of a large class of compounds characterized by a
     five-membered ring which contains an atom of nitrogen and at
     least one other noncarbon atom (nitrogen, oxygen, sulphur).
     The prefixes furo-, thio, and pyrro- are used to distinguish
     three subclasses of azoles, which may be regarded as derived
