We have recently reported the discovery of pyrrolo[3,2-d]pyrimidine derivatives 1a and 1b as potent triple inhibitors of vascular endothelial growth factor receptor (VEGFR), platelet-derived growth factor receptor (PDGFR), and Tie-2 kinases. To identify compounds having strong inhibitory activity against fibroblast growth factor receptor (FGFR) kinase, further modification was conducted using the co-crystal structure analysis of VEGFR2 and 1b. Among the compounds synthesized, urea derivative 11l having a piperazine moiety on the terminal benzene ring showed strong inhibitory activity against FGFR1 kinase as well as VEGFR2 kinase. A binding model of 11l complexed with VEGFR2 suggested that the piperazine moiety forms additional interactions with Ile1025 and His1026.

The invention relates to chemical compounds of the formula (I) or pharmaceutically acceptable salts thereof, which possess B Raf inhibitory activity and are accordingly useful for their anti cancer activity and thus in methods of treatment of the human or animal body. The invention also relates to processes for the manufacture of said chemical compounds, to pharmaceutical compositions containing them and to their use in the manufacture of medicaments of use in the production of an anti-cancer effect in a warm blooded animal such as man.
