New analogues of N-(2-aminoethyl)-4-chlorobenzamide (Ro 16-6491). Some of the most potent monoamine oxidase-B inactivators

Article abstract of DOI:10.1021/jm00076a026

A series of halo- and nitro-substituted analogues of N-(2- aminoethyl)benzamide has been synthesized. All of the compounds are competitive, time-dependent inhibitors of monoamine oxidase-B (MAO-B), but upon dialysis complete return of enzyme activity is observed for all compounds. Therefore, these are mechanism-based reversible inhibitors of MAO- B. The relative potencies of the compounds are rationalized in terms of steric and hydrophobic effects.
