Thienodiazepine

A thienodiazepine[1] is a heterocyclic compound containing a diazepine ring fused to a thiophene ring.

The core structure of thienodiazepines

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

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