Abstract

Diphenylhydantoin and diazepam are two useful antiepileptic drugs. Though not obviously related chemically, their molecular conformations exhibit marked similarities. These similarities indicate a steric basis for their anticonvulsant activity and lead to conclusions about the receptor sites for this type of pharmaceutical.
