摘要:
The present invention refers to analogues of 1,3-bis(4-nitrophenyl)triazenes, their pharmaceutically acceptable salts and N-acyl derivatives for the treatment of different types of tumors. Said compounds show cytotoxicity at very low concentrations (IC50 0.22 to 12.8 μM), and good solubility. These compounds can be used in the treatment of tumor patients as single drugs or in combination with other cytostatics.
摘要:
The present invention relates to novel triazene compounds, to a process for their preparation, to pharmaceutical compositions comprising them, and to the use thereof in the treatment of cancer diseases in humans. The novel triazene compounds are distinguished, as compared with the known triazene compounds, by improved activity while at the same time having reduced toxicity, that is to say by fewer side-effects.

Aromatic bistriazene compounds of the formula ##STR1## wherein --R.sub.1, --R.sub.2, --R.sub.3, and --R.sub.4 are independently --H, --C.sub.6 H.sub.5, --C.sub.6 H.sub.4 Y, or C.sub.1 -C.sub.4 alkyl; --R.sub.5 -- is ##STR2## --R.sub.6 is --F, --Cl, --Br, --CH.sub.3, or --CF.sub.3 ; r is 0, 1, 2, 3, or 4; and --Y is halogen, --NO.sub.2, --C.sub.6 H.sub.5, or C.sub.1 -C.sub.4 alkyl. These bistriazene compounds are useful for cross-linking polymers such as poly(imides), poly(aryl ether ketones), poly(aryl ether sulfones), poly(quinolines), poly(quinoxalines), and nonaromatic fluoropolymers having aliphatic C--H groups.
