The de novo design and synthesis of cyclic urea inhibitors of factor Xa: Initial sar studies

Article abstract of DOI:10.1016/S0960-894X(98)00471-5

In this report we discuss the design, synthesis, and validation of a novel series of cyclic urea inhibitors of the blood coagulation protein Factor Xa. This work culminates in compound 11, a monoamidine inhibitor of fXa employing a new S4 ligand that reduces the cationic character of these analogs. Compound 11 represents a lead for a series of more potent and selective inhibitors.
