Novel aryloxy-8-azabicyclo[3.2.1]oct-3-enes with 5-HT transporter and 5-HT1A affinity

Joining aryl 8-azabicyclo[3.2.1]oct-3-enes with aryloxyethanes and aryloxypropanes produces novel series of compounds 11 and 12 with potent 5-HT-T affinity and moderately potent 5-HT1A affinity. Moreover, several of these compounds possess functional 5-HT1A antagonism. Optimal compounds are, 4-indolyloxyethane 21, 4-indolyloxypropanes 25, and 27, which possess potent 5-HT-T affinity (5-HT-T Ki: 21: 1.2 nM, 25: 0.54 nM, 27: 0.38 nM) and good 5-HT1A affinity/antagonism (5-HT1AKi, [35S]GTPγS: Emax (%): 21: 111.1 nM, 0%; 25: 173.2 nM, 0%; 27: 107 nM, 0%).
