A series of N1-and N2-propargylphenelzine derivatives and analogues (1–7) was synthesized. In addition to their activity as monoamine oxidase inhibitors, two of the compounds, N1-and N2-propargylphenelzines (3 and 6), were found to be potent at preventing DSP-4-induced noradrenaline (NA) depletion in mouse hippocampus, suggesting that they have neuroprotective properties.
