Synthesis of some 2-(3,4-dimethoxy-phenyl)-1,3-propanediamines as potential dopaminergic agents.

: The bilateral diamino analogs namely N,N'-dialkyl-N,N'-diaralkyl- and N,N,N',N'-tetraalkyl-2-(3,4-dimethoxyphenyl)-1,3-propanediamine s were synthesized. The biochemical determination of the brain levels of dopamine and norepinephrine as well as of brain monoamine oxidase (MAO) activity was performed.
