Ellipticine (E) [5,11-dimethyl-6H-pyrido-(4,3-b)-carbazole, NSC-71795] is an antineoplastic agent which is active against L1210 lymphocytic leukemia in mice. Preclinical toxicologic studies demonstrated hemolysis in dogs and monkeys following intravenous administration of 1.5 mg/kg. This finding
The synthesis of hybrid "cationic metalloporphyrin-intercalator" molecules is reported. These molecules are based on 9-methoxyellipticine as intercalator and tris-(4-N-methylpyridiniumyl)metalloporphyrins having a 4-aminophenyl or a 4-hydroxyphenyl group for the attachment of the linker. The effect
A series of ellipticine glycosides [2-N-glycosyl quaternary pyridinium salts of three ellipticines: ellipticine (1), 9-methoxyellipticine (2), and 9-hydroxyellipticine (4)] were stereoselectively synthesized in good yields by an improved condensation reaction between ellipticines [1, 2, and
Starting from 2-(2-aminoethyl)-6-methoxy-1-methylcarbazole, ethyl 9-methoxy-5-methyl-6H-pyrido[4,3-b]carbazole-1-carboxylate was obtained through a three-step sequence. This compound and its 6-methyl derivative react with (dialkylamino)alkylamines to provide various
