Introduction
Benzodiazepines serve a central role in drug therapies which target central nervous system
disorders. Structure activity relationship (SAR) studies involving these agents have inspired the
generation of thousands of analogs. The 1,4-benzodiazepine ring system, represented by clinically
important drugs such as Diazepam (Valium®), has been the principal focus of much of this work.1
Hungarian researchers at the Institute of Drug Research, however, have centered a drug discovery
program on the structurally and pharmacologically distinct class of 2,3-benzodiazepine
