Diclazepam (also known as Chlorodiazepam) is a synthetic depressant substance of the benzodiazepine chemical class that produces effects similar to diazepam, such as anxiety suppression, disinhibition, anticonvulsant, hypnotic, muscle relaxing, and amnesia when administered. It was first synthesized by Leo Sternbach and his team at Hoffman-La Roche in 1960. In animal models it has a potency of approximately ten times that of diazepam, of which it is a structural analog.
Diclazepam is not currently marketed as a medication, but rather sold online as a research chemical. Its potency has not been systematically tested in humans, but its closest relatives and two main metabolites are lormetazepam with a potency value of x10-12 of delorazepam which is roughly x10 the potency of diazepam.
Diclazepam is a drug of the benzodiazepine class. Benzodiazepine drugs contain a benzene ring fused to a diazepine ring, which is a seven-membered ring with the two nitrogen constituents located at R1 and R4. At R1, diclazepam is substituted with methyl group. Further, the benzodiazepine ring is bonded at R5 to a 2-chlorinated phenyl ring. R7 of the benzyl ring is also substituted with a chlorine group. Diclazepam also contains an oxygen group double bonded to R2 of its diazepine ring to form a ketone. This oxygen substitution at R2 is shared with other benzodiazepine drugs with the suffix -azepam.
