2-Amino-4,7-dimethoxyindan Derivatives: Synthesis and Assessment of Dopaminergic and Cardiovascular Actions

Article abstract of DOI:10.1021/jm00349a019

N-Alkylated derivatives of 2-amino-4,7-dimethoxyindan were prepared for evaluation of central and peripheral dopaminergic activity using biochemical and behavioral tests in the rat and cardiovascular responses in the cat. 2-(Di-n-propylamino)-4,7-dimethoxyindan (4e) demonstrated equal activity with apomorphine to activate peripheral presynaptic dopamine receptors.Central pre- and postsynaptic dopamine receptors were also activated with 4e.In contrast to the intense long-acting sympathomimetic actions previously reported for the 2-amino-5,8-dimethoxytetralins, these compounds produced weak, transient effects in heart rate and blood pressure.The majority of 2-amino-4,7-dimethoxyindan derivatives tested are weak or inactive pre- and postsynaptic dopamine receptor agonists.
