Aza analogues of lucanthone: synthesis and antitumor and bactericidal properties

Three types of aza analogues of lucanthone were synthesized for evaluation as antitumor drugs. None of the compounds was found to have significant cytotoxic effects either on Friend tumor cells or on L1210 leukemia cells. However, one of the target compounds, 5,10-dihydro-10-oxo-1-[[3-(diethylamino)propyl]amino]-3-methylpyrido [4,3-b]quinoline, was shown to have noticeable antibiotic properties.
