Abstract:
Previously, we identified cyclohexane diamine derivative 1 as orally bioavailable factor Xa inhibitor. We have investigated two racemic cis-piperidine diamine derivatives 2 and 3 based on 1. Compounds 2a-e showed higher fXa inhibitory activity, anticoagulant activity, and aqueous solubility than 3a-e having same substituent. Compounds 2a, 2c, 2e, and 2g-m having sp2 nitrogen, especially amide and urea derivatives, showed potent anticoagulant activity. Compounds 2h and 2k showed high oral activities in rats.
