Abstract: The present invention provides methods of using aryl ureas to treat diseases and conditions associated with signal transduction pathways comprising at least one of raf, VEGFR, PDGFR, p38 and/or FLT-3. The present invention also provides compositions and methods for identifying conditions and diseases which can be modulated with compounds of the present invention. These methods facilitate the selection of subjects who can be efficiently treated with compounds of the present invention. Additionally, the invention provides methods for monitoring subjects who have been administered a compound of the present invention.

Abstract: This invention relates to a novel fused tricyclic heterocycle of the formula and its use for the treatment of hyper-proliferative disorders.

Abstract: The present invention provides methods for treating and/or preventing conditions and diseases in humans and other mammals that are associated with and/or mediated by signal transduction pathways comprising platelet-derived growth factor receptor (PDGFR) by administering diaryl ureas of Formula I. The present invention also provides devices and methods for treating, ameliorating, preventing, or modulating restenosis following angioplastic surgery or other invasive procedures that affect or injure the vascular system, and graft rejection following transplantation of a donor tissue into a host, where a stent or other omplantable device comprises an effective amount of diaryl ureas of Formula I.

Abstract: A compound of Formula (I): salts thereof, prodrugs thereof, metabolites thereof, pharmaceutical compositions containing such a compound, and use of such compound and compositions to treat diseases mediated by raf, VEGFR, PDGFR, p38 and flt-3.
