Abstract: Peptide mimetic compounds 9d and 9h showed good selectivity for FVIIa/TF over other serine proteases. Xray crystal structure analysis revealed that a large moiety at P3 interacted in a novel manner with the 170-loop and was accompanied by ligand-induced conformational change of the 170-loop. From additional optimization, we discovered compound 10b, an excellent extrinsic pathway-selective inhibitor.
