Abstact

A series of cis-1,2-diaminocyclohexane derivatives possessing a 6-6 fused ring for the S1 moiety were synthesized as novel factor Xa (fXa) inhibitors. The synthesis, structure-activity relationship (SAR), and physicochemical properties are reported herein, together with the discovery of compound 45c, which has potent anti-fXa activity, good physicochemical properties and pharmacokinetic (PK) profiles, including a reduced negative food effect.
