inhibition curves of various drugs ( serotonin , imipramine , desmethyl-imipramine , d-fenfluramine , d-norfenfluramine and indalpine , a potent serotonin uptake inhibitor ) obtained using 2 nm 3h-imi and in presence of 120 mm nacl , confirmed the presence of at least three 3h-imi binding sites : two of these ( high and low affinities ) were serotonin-insensitive while the third one was selectively inhibited by serotonin and indalpine with nanomolar affinities .
