Abstract: In the early 1990's, we reported on the low-molecular selective fXa inhibitor DX-9065a having two amidino groups. However, it had poor oral bioavailability due to its strong basic amidino groups. To obtain fXa inhibitors with improved oral bioavailability, we investigated various non-amidino fXa inhibitors and finally discovered cis-1,2-diaminocyclohexane derivative 4c to have potent fXa inhibition, promising anticoagulant activity, and good oral bioavailability, compared with amidino compound DX-9065a. In addition, we will discuss the influence of the third substituent on the cyclohexane ring on anti-fXa activity, anticoagulant activity, PK profile, and lipophilicity.
