We describe the synthesis of derivatives of 4,11-diaminonaphtho[2,3-f]indole-5,10-dione and their cytotoxicity for human tumor cells that express major determinants of altered anticancer drug response, the efflux pump P-glycoprotein, and non-functional p53. Nucleophilic substitution of methoxy groups in 4,11-dimethoxynaphtho[2,3-f]indole-5,10-dione with various ethylenediamines yielded the derivatives of 4,11-diaminonaphtho[2,3-f]indole-5,10-dione, the indole containing analogues of the antitumor agent ametantrone. The cytotoxicity of novel compounds for multidrug resistant, P-glycoprotein-expressing tumor cells is highly dependent on the N-substituent at the terminal amino group of the ethylenediamine moiety. Whereas p53 null colon carcinoma cells were less sensitive to the reference drug doxorubicin than their counterparts with wild type p53, the majority of novel naphthoindole derivatives were equally potent for both cell lines, regardless of the p53 status.
