Twenty-seven nitrated and non-nitrated compounds have been synthesized and tested for their growth
inhibitory activity on three human cancer cells lines. Fourteen compounds were able to inhibit more than 50% of the
growth of at least one of the cancer cell lines and five compounds exhibited high antiproliferative activity on human
cancer cell lines (IC50 < 8.5 μM). The cytotoxicity of the compounds on Vero cell line was established in vitro to evaluate the selectivity.
All active compounds have a good leaving group (bromide or chloride) at the benzylic position, indicating that the mechanism of action
of these compounds is related to their alkylating properties. Two compounds (3 and 24) were selected for further studies in mice with
Ehrlich solid tumors and display significant antitumor effects in vivo.
Keywords: Antitumor activity, alkylating agents, bioreduction, cytotoxicity, nitrocompounds, solid tumor.
