Heterocyclic compounds inhibiting angiogenesis

摘要

The invention relates to compounds of general formula (I) wherein R stands for a group of general formula -COOR<1>, -CONR<2>R<3>, -CONR<4>CONR<4>R<5> or -CH2OR<6>, wherein R<1> stands for a C2-6 alkyl group; a C1-6 alkyl group substituted; or a C3-6 cycloalkyl group; R<2> and R<3> are identical or different and stand independently from each other for hydrogen atom or a C1-6 alkyl group which optionally may be substituted; a 5- or 6-membered cycloalkyl or a heteroaryl group; and their tautomers, solvates and the mixtures thereof and acid addition salts of these compounds. The invention also relates to pharmaceutical compositions comprising compounds of general formula (I) as active agent. The angiogenesis-inhibitors according to the invention inhibit the neovascularisation in living tissues and as such can be used for preventing and inhibiting angiogenesis appearing in connection with tumour growth and for preventing the formation of tumour metastases.
