ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to lactam inhibitors of serine proteases such as Factor Xa and tryptase, which are useful as anticoagulants in the treatment of cardiovascular diseases associated with thromboses, and as anti-inflammatory agents particularly in the treatment of chronic asthma and related diseases.
