The study investigates the synthesis and psychopharmacological activity of benzhydrylglycine derivatives (compounds I-VI) to explore their structure-activity relationship. The chemicals involved include methyl N-(2-oxy-5-bromobenzhydryl)glycine (I), N-(2-oxy-5-bromobenzhydryl)glycine (II), methyl N-(2-chloro-5-bromobenzhydryl)glycine (III), ammonium oxide N-(2-amino-5-bromobenzhydryl)glycine (IV), methyl N-(2-acetamido-5-bromobenzhydryl)glycine (V), and methyl N-[2-(o-chlorobenzamido)-5-bromobenzhydryl]glycine (VI). These compounds were synthesized and tested for their antiamnesia activity and effects on various reflexes and muscle tone in rodents. The study found that the antiamnesia activity of these compounds depends on the substituents R and R' on the benzhydryl fragment and glycine residue, with compounds V and VI showing higher activity.
