Two series of 17 tetrahydroquinoline compounds (2,4-DAr-THQs and DSQs), in which the 4-methoxy-3- hydroxyphenyl (isovanillin) structural unit is incorporated, were tested for their potential human tumor cell growth inhibitory effect on MCF-7, SKBR-3, PC3, HeLa and for non-tumor cells (primary culture of human dermis fibroblast – control cells) for the first time. The THQ 8 is an interesting model for antitumoral drugs, displaying cytotoxic activity against MCF7, SKBR3 or PC3 (IC50 7.99 - 16.14 μM) with the selectivity index 3.4 for MCF7.
