Isoindoledione compounds of the formula: ##STR1## wherein: R.sub.1 and R.sub.3 each separately is phenyl, substituted phenyl, alkyl of 1 to 4 carbons, --CHO, --CH.sub.2 OR.sub.6, --CO.sub.2 R.sub.6, --COR.sub.6, hydrogen, or together with R.sub.2 is a divalent alkyl or alkenyl group of 3 to 5 carbons which form a cyclic ring; R.sub.2 is phenyl, substituted phenyl, --CH.sub.2 OR.sub.6, --CH.sub.2 CH.sub.2 OR.sub.6, alkyl of 1 to 4 carbons or with either R.sub.1 or R.sub.3 is a divalent alkyl or alkenyl group of 3 to 5 carbons which form a cyclic ring; R.sub.4 and R.sub.5 which may be the same or different each separately is hydrogen, alkyl of 1 to 4 carbons, --OR.sub.6, --CO.sub.2 R.sub.6, --COR.sub.6, --CHO, --CH.sub.2 OR.sub.6 or together R.sub.4 and R.sub.5 is a butadiene radical which forms a benzene ring; R.sub.6 is hydrogen or alkyl of 1 to 4 carbons; provided that R.sub.1 and R.sub.3 are not both phenyl and that when R.sub.4 and R.sub.5 are both hydrogen, R.sub.1, R.sub.2 and R.sub.3 are not all methyl. The compounds are useful as radio-sensitizers in the therapeutic radiation of cancerous tissues.
