STR1 New 6-[X-(2-hydroxyethyl)aminoalkyl]-5,11-dioxo-5,6-dihydro-11H-indeno[-1,2-c]isochinoline derivatives represented by general formula (I), in which X stands for the number of carbon atoms from 0 to 5 in aminoalkyl group situated on nitrogen atom in position 6 of the indenoisochinoline fundamental structure, their salts with inorganic and organic acids and their derivatives were described. Antitumorously effective indenoisochinoline derivatives are most preferably prepared by the process in which the indeno[1,2-c]isocoumarine and/or 1-methoxy-2-(2-methoxycarbonylphenyl)-1-inden-3-one, respectively, comprises reacting with N-(hydroxyethyl)alkylen diamine in a medium of suitable aprotic solvent, preferably dimethylformamide, and at increased temperature. Another process for the preparation comprises reacting 6-(X-chloroalkyl)-5,11-dioxo-5,6-dihydro-11H-indeno[1,2-c]isochinolines with 2-aminoethanol in suitable solvent, preferably dimethylformamide, in the presence of anhydrous potassium carbonate. New compounds, their derivatives and salts are useful for the preparation of drugs and compositions for the treatment of malignant neoplasias in mammals.
