The compounds have the formula ##STR1## wherein R 1 stands for various organic radicals as defined in the body of the specification and X is a 4-, 5- or 6-member ring or fused double ring which includes a nitrogen atom in the ring attached to the keto-aldehyde group and wherein the latter ring is substituted by =O in the two positions ortho to said nitrogen atom. The compounds are anti-bacterial, anti-viral and anti-neoplastic agents and are valuable in connection with combatting the rejection mechanism in transplantations. They are furthermore useful as radiosensitizers in connection with radiation treatments for various purposes.
