ABSTRACT:
The present invention provides a method for treating a thrombotic or an inflammatory disorder administering to a patient in need thereof a therapeutically effective amount of at least one compound of Formula (I) or Formula (V):or a stereoisomer or pharmaceutically acceptable salt or solvate form thereof, wherein the variables A, L, Z, R3, R4, R6, R11, X1, X2, and X3are as defined herein. The compounds of Formula (I) are useful as selective inhibitors of serine protease enzymes of the coagulation cascade and/or contact activation system; for example thrombin, factor Xa, factor XIa, factor IXa, factor VIIa and/or plasma kallikrein. In particular, it relates to compounds that are selective factor XIa inhibitors. This invention also provides compounds within the scope of Formula I and relates to pharmaceutical compositions comprising these compounds.
