SAR and X-ray Structures of Enantiopure 1,2-cis-(1R,2S)-cyclopentyldiamine and Cyclohexyldiamine Derivativies as Inhibitors of Coagulation Factor Xa

Journal Article · · BioOrganic and Medicinal Chemistry Letters

In the search of Factor Xa (FXa) inhibitors structurally different from the pyrazole-based series, we identified a viable series of enantiopure cis-(1R,2S)-cycloalkyldiamine derivatives as potent and selective inhibitors of FXa. Among them, cyclohexyldiamide 7 and cyclopentyldiamide 9 were the most potent neutral compounds, and had good anticoagulant activity comparable to the pyrazole-based analogs. Crystal structures of 7-FXa and 9-FXa illustrate binding similarities and differences between the five- and the six-membered core systems, and provide rationales for the observed SAR of P1 and linker moieties.
