Thienodiazepine

The core structure of thienodiazepines

Not to be confused with thienobenzodiazepine or thienotriazolodiazepine.

A thienodiazepine is a heterocyclic compound containing a diazepine ring fused to a thiophene ring.

If R1 and R2 are part of a triazole ring, the substance is called a "thienotriazolodiazepine."

The thienodiazepine structure forms the central core of some pharmaceutical and recreational drugs, including:

• Bentazepam
• Clotiazepam
• Etizolam
• Metizolam
• Deschloroetizolam

Since thienodiazepines interact with the benzodiazepine receptor site, they typically have similar effects as benzodiazepines.
