Factor Xa has materialized as a key enzyme for the intervention of blood coagulation cascade and for the development of new antithrombotic agents. It is the lone enzyme that is responsible for the production of thrombin and is therefore an attractive target for the control of thrombus formation. The biological activities (log 1/IC50) of anthranilamide-based factor Xa inhibitors were quantitatively analyzed in terms of physicochemical parameters by the regression analysis. Structural requirements for maximal potency were derived from the results of a quantitative structure activity relationship analysis. The leave-one-out cross-validation method was used to judge the predictive power of final equations.
