Pyrido[4,3‐e]‐1,4‐diazepines and Pyrido[4,3‐b]‐1,5‐benzodiazepines: Synthesis and Affinity to Brain Benzodiazepine Receptors

Abstract
Pyrido[4,3‐e]‐1,4‐diazepines and fused tricyclic analogs thereof have been synthesized and tested for inhibition of benzodiazepine binding to receptors in various rat brain structures in comparison with standard drugs. Structure‐affinity relationships are discussed.
