The compounds of formula I also can include isotopic labels. For example the compounds 2-[1-methyl-5-(phenylsulfonyl)-1H-indol-3-yl]ethanamine; 2-[1,2-dimethyl-5-(phenylsulfonyl)-1H-indol-3-yl]-N-methylethanamine; 2-[1,2-dimethyl-5-(phenylsulfonyl)-1H-indol-3-yl]ethanamine; 2-{5-[(3,5-difluorophenyl)sulfonyl]-1,2-dimethyl-1H-indol-3-yl}ethanamine; 2-{5-[(3,5-difluorophenyl)sulfonyl]-1,2-dimethyl-1H-indol-3-yl}-N-methylethanamine; 2-[2-methyl-5-(1-naphthylsulfonyl)-1H-indol-3-yl]ethanamine; and pharmaceutically acceptable salts thereof may contain an isotopic label such as at least one atom selected from Carbon-11, Nitrogen-13, Oxygen-15, and Fluorine-18. Isotopically labeled compounds may be used in positron emission tomography.
