A new series of fluoro-, methoxyl-, and amino-substituted isoflavones have been synthesized as potential antitumor agents based on structural similarities to known flavones and isoflavones (quercetin and genistein respectively) and antitumor 2-phenylbenzothiazoles. Target compounds were synthesized using palladium-catalyzed coupling methodologies to construct the central aryl carbon-carbon single bond. The new isoflavone derivatives were tested for in vitro activity in human breast (MDA-MB-468 and MCF-7) and colon (HT29 and HCT-116) cancer cell lines. Low micromolar GI50 values were obtained in a number of cases, with the MDA-MB-468 cell line being the most sensitive overall. Notably, significant potentiation of growth inhibitory activity (GI50 1 μM for 12d, 12f, 12h, 12k, 121, 12o but not the methylene-bridged derivative 12i) was observed when MDA-MB-468 cells were co-incubated with TBDD, a powerful inducer of cytochrome P450 (CYP)-1A1 activity, suggesting that isoflavone derivatives can act as substrates for CYP1A1 bioactivation.
