To develop a potent and oral anticoagulant, a series of compounds with cinnamyl moiety was synthesized and their factor Xa (FXa) inhibitory activities were examined. As a result, some cinnamyl derivatives showed potent FXa inhibitory activities in vitro. Among them, compounds with substituent at the 3-position on the central benzene ring represented by (N-{4-[1-(acetimidoyl)piperidin-4-yloxy]-3-chlorophenyl}-N-[(E)-3-(3-amidinophenyl)-2-propenyl]sulfamoyl)acetic acid dihydrochloride (45b) and (N-{4-[1-(acetimidoyl)piperidin-4-yloxy]-3-carbamoylphenyl}-N-[(E)-3-(3-amidinophenyl)-2-propenyl]sulfamoyl)acetic acid dihydrochloride (45j) exhibited potent FXa inhibitory activities with IC(50) values of less than 10 nM in vitro. These compounds also showed potent anticoagulant activities both in vitro and ex vivo. Furthermore, these compounds exhibited no lethal toxicity (30 mg/kg, i.v.).

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.
