The synthesis of new substituted E-3-(3-indolylmethylene)1,3-dihydroindol-2-ones is reported. The antiproliferative activity was evaluated according to protocols available at the National Cancer Institute (NCI), Bethesda, MD. The action of the most active compound 10 was further investigated in HL-60 leukemia cells. Results obtained show that it causes a block in cell cycle progression, with cell arrest in the G2/M phase, associated with activation of apoptosis accompanied with increased oxidative stress and deregulation of the homeostasis of divalent cations, with significant increase in the cellular concentrations of free Ca2+ and Mg2+.
