The ethyl esters 1a‐1j and 2a‐2j of N‐acyl amino acids were synthesized by the DCC method. The compounds were screened for their monoamine oxidase (MAO) inhibitory activity (in vitro) and various CNS activities (in vivo). Some compounds showed promising MAO inhibitory and anti‐depressant activities. The compounds did not produce acute neurological deficits and have low toxicity.
