Two sets of new o-methoxyphenylpiperazine (MPP; series a) and 1,2,3,4-tetrahydroisoquinoline (THIQ; series b) derivatives, containing various imide moietiesderived from NAN190, were synthesized and evaluated in vitro for their ability to bind tothe serotonin 5-HT1A and 5-HT2A receptors. All new derivatives from series a demonstratedhigh 5-HT1A affinities, whereas THIQ analogues were much less active. With respect to5-HT2A receptors, three MPP derivatives presented moderate activity but the rest of theinvestigated compounds were practically inactive. The influence of changes in terminusgeometry on 5-HT1A receptor affinity was analyzed in regard to model compounds NAN190and MM199.
