By chemical modification of a known prolyl endopeptidase (PEP) inhibitor (N-[N-(4-phenylbutanoyl)-L-prolyl]pyrrolidine; SUAM-1221), several arylalkanoyl derivatives (V-1-27) were synthesized and tested for in vitro inhibitory activity towards PEP from canine brain. Among them, 4-(2-thienyl)butanoyl derivatives (V-24-27) showed more potent PEP-inhibitory activity than SUAM-1221. The structure-activity relationships of these compounds are discussed.
