The invention relates to compounds of formula I,
wherein r is 0 to 2, n is 0 to 2; m is 0 to 4; R1 and R2 (i) are in each case a lower alkyl, or (ii) together form a bridge in subformula I*
or (iii) together form a bridge in subformula I**
wherein one or two of the ring members T1, T2, T3, and T4 are nitrogen, and the remainder are in each case CH; A, B, D, and E are N or CH, wherein not more than 2 of these radicals are N; G is lower alkylene, acyloxy- or hydroxy-lower alkylene, —CH2—O—, —CH2—S—, —CH2—NH—, oxa, thia, or imino; Q is methyl; R is H or lower alkyl; X is imino, oxa, or thia; Y is aryl, pyridyl, or (un)substituted cycloalkyl; and Z is mono- or disubstited amino, halogen, alkyl, substituted alkyl, hydroxy, etherified or esterified hydroxy, nitro, cyano, carboxy, esterified carboxy, alkanoyl, carbamoyl, N-mono- or N,N-disubstituted carbamoyl, amidino, guanidino, mercapto, sulfo, phenylthio, phenyl-lower alkylthio, alkylphenylthio, phenylsulfinyl, phenyl-lower alkylsulfinyl, alkylphenylsulfinyl, phenylsulfonyl, phenyl-lower alkylsulfonyl, or alkylphenylsulfony; and wherein the bonds characterized by a wavy line are either single or double bonds; or an N-oxide of said compound with the stipulation that, if Y is pyridyl or unsubstituted cycloalkyl, X is imino, and the remaining radicals are as defined, then G is selected from the group comprising lower alkylene, —CH2—O—, —CH2—S—, oxa and thia; or a salt thereof. The compounds inhibit angiogenesis.
