In vitro cytotoxicity study of carbazole III 3-amino and 3-nitro-1,4-dimethyl-9H-carbazoles derivatives, diversely substituted in 6. The synthesis of a series of nitro and amino-1,4-dimethyl-9H-carbazoles is described. Their cytotoxic activities, as assayed in vitro using clonogenic cell culture of murine leukemia L1210, vary greatly with the nature and position of substituents. The most cytotoxic derivatives, 3-amino-6-hydroxy 1,4-dimethyl-9H-carbazole, displays an activity similar to that of N2-methyl-9-hydroxy ellipticinium acetate (NMHE). These results, together with those previously published by us, allow a detailed analysis of structure-activity relationships in the 9H-carbazole and 1,4-dimethyl-9H-carbazole series. For the 3-amino-1,4-dimethyl 9H-carbazole derivatives, a mechanism of action similar to that of ellipticine derivatives is proposed.
