Substituted E-3-(3-indolylmethylene)1,3-dihydroindol-2-ones with antiproliferative activity. Study of the effects on HL-60 leukemia cells
摘要:
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+.

were synthesized and tested as specific inhibitors of mitochondrialNADHdehydrogenase. The position of the phenyl ring and the geometrical configuration play an important role in the activity and specificity of these derivatives. In order to study the mechanism of action of these thienylvinylindoles, their activity was compared with that of known inhibitors in a new test employing exogenous quinones

Seven indoles bearing a thienylvinyl group, present in the well known anthelmintic drug pyrantel, were synthesized and tested as inhibitors of the mitochondrial energy metabolism in order to recognize selective compounds (active on the mitochondria of helminthic parasites but inactive on the mitochondria of birds and mammals). 1-Phenyl-2-chloro-3-(2-thienylvinyl)indole 14, showing this biochemical behaviour, was also tested on Parascaris equorum living worms, confirming its activity on the energy metabolism.
