Popis: In the search for new antidepressants with a rapid onset of action, fenmetazole analogues, bearing a second phenyl ring in a position previously shown not to be detrimental to affinity and selectivity for the α2-adrenoreceptors, were synthesized in an attempt to combine NA-uptake inhibition and blockade of the α2-adrenoreceptors in the same molecule. Some of the new molecules showed enhanced affinity and selectivity for the α2-adrenoreceptors compared to fenmetazole. Surprisingly, introduction of a phenyl ring in the structure of fenmetazole changed the agonistic action of the parent compound toward the α1-adrenoreceptors into an antagonistic effect. However, none of the new derivatives showed in vitro NA-uptake inhibitory potency substantially different from the low activity of fenmetazole in this test.
