In order to identify new aromatase enzyme inhibitors, thirty aryl sulfonamide derivatives containing an indole nucleus have been synthesized. The enzyme inhibition assay showed that four compounds inhibitaromatase in the sub-micromolar range. Loading concentrations of these four compounds were afterwards tested for cell viability and cytotoxicity on MCF7 human breast cancer cells, revealing a time-
