N-Alkylated (S)-7-halogen-5-[1-(2-methoxymethylpyrrolidinyl)sulfonyl]isatins were developed as a new group of nonradioactive reference compounds for future radiotracers. Inhibitor potency studies of these compounds suggest that the binding pockets readily accommodate both the 7-halogen substituents and aliphatic side chains (methyl to n-butyl) as
