Synthesis and structure–activity relationship of 2-(aminoalkyl)-3,3a,8,12b-tetrahydro-2H-dibenzocyclohepta[1,2-b]furan derivatives: a novel series of 5-HT2A/2C receptor antagonists

Following the program started at Johnson & Johnson Pharmaceutical Research & Development searching for 5-HT2A/2C antagonists we now report on the synthesis of a series of substituted 2-(aminomethyl)-3,3a,8,12b-tetrahydro-2H-dibenzocyclohepta[1,2-b]furan derivatives. The 5-HT2A, 5-HT2C and H1 receptor affinities of the described compounds are reported. The mCCP antagonistic activity of a set of selected molecules is also reported.
