Abstract/OtherAbstract:
2-phenyl-1H-benzimidazoles 7a-e were synthesized and tested for gene activation on ERalpha-positive MCF-7 breast cancer cells, stably transfected with the reporter plasmid EREwtcluc (MCF-7-2a cells). None of the compounds showed agonistic properties, but they antagonized dependent on hydroxyl groups at the benzimidazole core (5- or 6-OH) and at the aromatic ring in the 2-position (4-OH) in high concentrations the gene activation induced by estradiol (E2, 1 nM). All compounds exhibited significant antiproliferative properties on MCF-7 cells but they were inactive against hormone independent, ER negative MDA-MB-231 cells.
