    • The present invention relates to angiogenesis inhibitors, in particular receptor tyrosine kinase inhibitors, and their use for the treatment of hyperproliferative diseases, angiogenesis and disorders depending on angiogenesis such as tumour forming cancers. It also relates to a method of inhibiting angiogenesis or treating a vascular anomaly in a mammal comprising administering to the mammal an amount of an Eph receptor inhibitor which is effective for inhibiting angiogenesis or for treating the vascular anomaly in the mammal. Further, the present invention relates to the use of compounds for the treatment of angiogenesis related disorders involving a protein kinase, preferably a tyrosine kinase, and to some specific forms of said compounds as a medicament. Compounds useful in the practice of the invention have the general formula I wherein R1, R2, R3, R4 and R5 are as defined in the specification.
