Dibenzazecines are a novel class of dopamine receptor antagonists, characterized by their high affinities as well as their tendency for D1selectivity. Hitherto, the most active dibenzazecines were phenolic in nature; a 3‐OH substituent was found to result in the highest affinities. However, the phenolic nature of these compounds mostly renders them unsuitable forin vivoapplication, due to the poor pharmacokinetic profile, imparted by the phenolic group. A novel dibenzazecine derivative was prepared, with methylenedioxy moiety, connecting C(2) amd C(3), instead of the 3‐OH group. The newly synthesized derivative3showed high affinities similar to the lead LE404, displaying nanomolar affinities for all dopamine receptor subtypes. Its dibrominated derivative4, though exhibiting almost a fivefold decrease in affinities, still displayed nanomolar ones for all dopamine receptors, except for D4. In a functional Ca2+assay, both compounds3and4were found to possess antagonistic properties towards the dopamine receptors.
