Chemical compounds having structural formula I and physiologically acceptable salts thereof, are inhibitors of serine/threonine and tyrosine kinase activity. Several of the tyrosine kinases, whose activity is inhibited by these chemical compounds, are involved in angiogenic processes. Thus, these chemical compounds can ameliorate disease states where angiogenesis or endothelial cell hyperproliferation is a factor. These compounds can be used to treat cancer and hyperproliferative disorders.
Compounds of formula (I) :
are antithrombotic agents, having utility in a variety of therapeutic areas including the prevention and/or treatment of deep vein thrombosis (DVT) after surgery, major medical illness, paralysis, malignancy, prolonged immobilisation trauma, application of lower limb plaster casts, or fractures of the lower limbs or pelvis; recurrent DVT; DVT during pregnancy when there is a previous history thereof; reocclusion following thrombolytic therapy; chronic arterial obstruction; peripheral vascular
disease; acute myocardial infarction; unstable angina; atrial fibrillation; thrombotic stroke; transient ischaemic attacks; disseminated intravascular coagulation; coagulation in extra-corporeal circuits; occlusion of arterio-venous shunts and blood vessel grafts (including coronary artery by-pass grafts); and restenosis and occlusion following angioplasty.
