To develop a novel and effective anticoagulant with potent and selective factor Xa (FXa) inhibitory activity, a new series of cinnamyl derivatives with enhanced lipophilicity and prodrug forms were synthesized and their biological activities were evaluated. As a result, we found that cinnamyl derivative (N-{4-[1-(acetimidoyl)piperidin-4-yloxy]-3-carbamoylphenyl}-N-[(Z)-3-(3-amidinophenyl)-2-fluoro-2-propenyl]sulfamoyl)acetic acid dihydrochloride (26d, R-142086) with a fluorine atom on the double bond exhibited potent anticoagulant activity and no mutagenic potential. Moreover, orally administered R-142086 exhibited potent anti-FXa activity and anticoagulant activity in dogs.

A series of [2-(ω-phenylalkyl)phenoxy]alkylamines was synthesized and their 5-hydroxytryptamine2 (5-HT2) and/or dopamine2 (D2) receptor antagonistic activities were examined in vitro. [2-(4-Phenylbutyl)phenoxy]alkylamines showed strong inhibition of both 5-HT2 and D2 receptors. It particular, [2-(4-phenylbutyl)phenoxy]-methylpiperidine derivatives, 10b, 10i and 10q, exhbited potent inhibition. The structure-activity relationships in this series of compounds are discussed.

A series of [2-(ω-phenylalkyl)phenoxy]alkylamines was synthesized and thir receptor binding affinity was examined in vitro. These compounds showed an affinity for serotonin-2 (5-HT2) and dopamine-2 (D2) receptors. [2-(2-phenylethyl)phenoxy]alkylamine derivatives with a pyrrolidine or piperidine moiety in the structure showed higher affinity for 5-HT2 receptors but lower affinity for D2 receptors. Among these compounds, (S)-2-[2-[2-[2-(3-methoxyphenyl)ethyl]phenoxy]ethyl]1-methylpyrrolidine, (S)-27, exhibited the most potent and selective affinity for 5-HT2 receptors. Furthermore, (S)-27 was effective in inhibiting 5-HT-induced vasoconstriction in vitro and platelet aggregation both in vitro and ex vivo.
