1 None were found to be a substrate for either enzyme, but many of these isoquinolines could selectively inhibit either MAO A or B. Stereoselective competitive inhibition of MAO A was found with the R enantiomer of all the stereoisomers tested, including salsolinol (Ki = 31 microM), salsoline (Ki = 77 microM), salsolidine (Ki = 6 microM), and carnegine (Ki = 2 microM). salsoline monoamine oxidase A Homo sapiens
