  Design and Synthesis of Isoxazoline Derivatives as Factor Xa Inhibitors. 1

  摘要：

  Thrombosis is a major cause of mortality in the industrialized world. Therefore, the prevention of blood coagulation has become a major target for new therapeutic agents. One attractive approach is the inhibition of factor Xa (FXa), the enzyme directly responsible for protbrombin activation. We report a series of novel biaryl-substituted isoxazoline derivatives in which the biaryl moiety was designed to interact with the S-4 aryl-binding domain of the FXa active site. Several of the compounds herein have low nanomolar affinity for FXa, have good in vitro selectivity for FXa, and show potent antithrombotic efficacy in vivo, The three most potent compounds (33, 35, and 37) have inhibition constants for human FXa of 3.9, 2.3, and 0.83 nM, respectively, and ID50's ranging from 0.15 to 0.26 mu mol/kg/h in the rabbit arterio-venous thrombosis model.

  Intravascular clot formation is an important factor in a number of cardiovascular diseases, Therefore, the prevention of blood coagulation has become a major target for new therapeutic agents. One attractive approach is the inhibition of factor Xa (FXa), the enzyme directly responsible for thrombin activation. Herein we report a series of isoxazoline derivatives which are potent FXa inhibitors. Optimization of the side chain at the quaternary position of the isoxazoline ring led to SK549 which showed subnanomolar FXa potency (K-i 0.52 nM). SK549 shows good selectivity for FXa compared to thrombin and trypsin, potent antithrombotic effect in the rabbit arterio-venous thrombosis model, and improved pharmacokinetics relative to other compounds evaluated from this series.

  Factor Xa (fXa) plays a critical role in the coagulation cascade, serving as the point of convergence of the intrinsic and extrinsic pathways. Together with nonenzymatic cofactor Va and Ca2+ on the phospholipid surface of platelets or endothelial cells, factor Xa forms the prothrombinase complex, which is responsible for the proteolysis of prothrombin to catalytically active thrombin. Thrombin, in turn, catalyzes the cleavage of fibrinogen to fibrin, thus initiating a process that ultimately leads to clot formation. Recently, we reported on a series of isoxazoline and isoxazole monobasic noncovalent inhibitors of factor Xa which show good potency in animal models of thrombosis. In this paper, we wish to report on the optimization of the heterocyclic core, which ultimately led to the discovery of a novel pyrazole SN429 (2b; fXa K-i = 13 pM). We also report on our efforts to improve the oral bioavailability and pharmacokinetic profile of this series while maintaining subnanomolar potency and in vitro selectivity. This was achieved by replacing the highly basic benzamidine P-1 with a less basic benzylamine moiety. Further optimization of the pyrazole core substitution and the biphenyl P-4 culminated in the discovery of DPC423 (17h), a highly potent, selective, and orally active factor Xa inhibitor which was chosen for clinical development.
