Azole
From Wikipedia, the free encyclopedia
An azole is a class of five-membered nitrogen heterocyclic ring compounds containing at least one other noncarbon atom, nitrogen, sulfur or oxygen.[1] The parent compounds are aromatic and have two double bonds; there are successively reduced analogs (azolines and azolidines) with less. Names of azoles maintain the prefix upon reduction (such as pyrazoline, pyrazolidine), except for pyrrole, which has no -azole suffix and is reduced to pyrroline and pyrrolidine.

[edit] Examples
The azoles include:
- 1 nitrogen
- 2 or more nitrogen atoms
- 1 nitrogen atom and 1 sulfur atom
A "dioxole" is a similar compound with two oxygen atoms in a five membered ring. Dioxolane is a derivative of dioxole.
[edit] Uses
Many azoles are used as antifungal drugs (azole antifungals), inhibiting the fungal enzyme 14α-demethylase which produces ergosterol (an important component of the fungal plasma membrane).
