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.
The present application describes oxygen and sulfur containing heteroaromatics and derivatives thereof of formula
or pharmaceutically acceptable salt or prodrug forms thereof, wherein J is O or S and D may be C(═NH)NH2, which are useful as inhibitors of factor Xa.
