Mitindomide

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** A bisdioxopiperazines analog with antineoplastic activity. Mitinomide inhibits topoisomerase II and slowly promotes DNA-interstrand cross-linking, thereby inhibiting DNA repair, RNA and protein synthesis. This agent acts without increasing topoisomerase II-DNA covalent cleavable complex formation, as do most topoisomerase inhibitors. (NCI04)

**Synonyms:** - 4, 8-Ethenopyrrolo[3',4':3,4]cyclobut[1,2-f]isoindole-1,3,5,7(2H, 6H)tetrone, octahydro- - MITINDOMIDE
