The invention relates to compounds of formula I wherein r is from 0 to 2; n is from 0 to 2; m is from 0 to 4; A, B, D and E are each independently of the others N or CH, with the proviso that not more than two of those radicals are N; G is lower alkylene, -CH2-O-, -CH2-S-, -CH2-NH-, oxa (-O-), thia (-S-) or imino (-NH-), or is lower alkylene substituted by acyloxy or by hydroxy; Q is lower alkyl, especially methyl; R is H or lower alkyl; X is imino, oxa or thia; Y is lower alkyl or, especially, aryl, heteroaryl or unsubstituted or substituted cycloalkyl; and Z is amino, mono- or di-substituted amino, halogen, alkyl, substituted alkyl, hydroxy, etherified or esterified hydroxy, nitro, cyano, carboxy, esterified carboxy, alkanoyl, carbamoyl, N-mono- or N,N-di-substituted carbamoyl, amidino, guanidino, mercapto, sulfo, phenylthio, phenyl-lower alkylthio, alkylphenylthio, phenylsulfinyl, phenyl-lower alkylsulfinyl, alkylphenyl-sulfinyl, phenylsulfonyl, phenyl-lower alkanesulfonyl or alkylphenylsulfonyl, and where, if more than one radical Z is present (m>=4), the substituents Z are identical or different; and wherein the bonds indicated by a wavy line are either single bonds or double bonds; or an N-oxide of the mentioned compound, wherein one or more N atoms carry an oxygen atom; or a salt thereof. The compounds inhibit especially angiogenesis.
