With the aim of obtaining new antitumor drugs more active than previously described 11H-indolo[3, 2-c]quinoline-1, 4-diones and 7, 8, 9, 10-tetrahydro-11H-indolo[3, 2-c]quinoline-1, 4-diones, the synthesis and activities of a series of 3-substituted 11H-pyrido[3', 4' : 4, 5]pyrrolo[3, 2-c]quinoline-1, 4-diones and of 7, 8, 9, 10-tetrahydro-11H-pyrido-[3', 4' : 4, 5]pyrrolo[3, 2-c]quinoline-1, 4-diones were studied. Some quinones were more cytotoxic in vitro towards L1210 leukemia cells but were not active in vivo towards murine P388 leukemia.
