The invention relates to compounds of formula I ##STR1## 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, --CH.sub.2 --O--, --CH.sub.2 --S--, --CH.sub.2 --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.gtoreq.2), 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.

De uitvinding heeft op samenstellingen van formule I ## STR1 ## betrekking waarin r van 0 tot 2 is; n is van 0 tot 2; m is van 0 tot 4; A, B, D en E zijn elk onafhankelijk van anderen N of CH, op voorwaarde dat niet meer dan twee van die basissen N zijn; G is lagere alkylene, -- CH.sub.2 o --, -- CH.sub.2 --S --, -- oxa CH.sub.2 -NH --, (- - thia van O --), (- - S) of imino (- - NH --), of is lagere alkylene die door acyloxy of door hydroxy wordt gesubstitueerd; Q is lagere vooral methyl alkyl; R is H of lagere alkyl; X is imino, oxa of thia; Y is lagere alkyl of, vooral, aryl, heteroaryl of unsubstituted of gesubstitueerde cycloalkyl; en Z is amino, mono - of di-substituted amino, halogeen, alkyl, gesubstitueerde alkyl, hydroxy, etherified of geëstrificeerde hydroxy, nitro, cyano, carboxy, geëstrificeerde carboxy, alkanoyl, carbamoyl, n-Mono - of N, n-Di-Gesubstitueerde carbamoyl, amidino, guanidino, mercapto, sulfo, phenylthio, phenyl-lagere alkylthio, alkylphenylthio, phenylsulfinyl, phenyl-lagere alkylsulfinyl, alkylphenyl-sulfinyl, phenylsulfonyl, phenyl-lagere alkanesulfonyl of alkylphenylsulfonyl, en waar, als meer dan één radicaal Z (m.gtoreq.2) aanwezig is, de substituenten Z identiek of verschillend zijn; en waarin de banden die door een golvende lijn worden vermeld of enige banden of dubbele banden zijn; of een n-Oxyde van de vermelde samenstelling, waarin één of meerdere atomen van N een zuurstofatoom dragen; of een zout daarvan. De samenstellingen remmen vooral angiogenese.
