Thioxanthene

Thioxanthene is a molecule in which the oxygen atom in xanthene is replaced with a sulfur atom.

Thioxanthene derivatives include:
 * Chlorprothixene
 * Flupenthixol
 * Thiothixene
 * Zuclopenthixol

These drugs are antipsychotic drugs. The thioxanthene class of neuroleptic antipsychotic psychotropics is closely related to the phenothiazines which are very similar pharmacologically.
