title: Chiral 1,4-benzodiazepin-2-ones: relationship between stereochemistry and pharmacological activity.
abstract: Pure enantiomers of 3-substituted-1,4-benzodiazepin-2-ones, obtained by HPLC resolution on chiral stationary phases, show significant differences in their pharmacological activity. The occurrence of biotransformation during the pharmacological test is monitored using a new chromatographic method. The reliability of the pharmacological activity data is discussed.
