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. | 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.
