Led by Professor Cohen-Armon of Tel-Aviv University, the researchers found that potent phenanthridine derived polyADP-ribose polymerase (PARP) inhibitors efficiently eradicate MCF-7 and MDA231 breast cancer cells without impairing normal proliferating cells, such as human epithelial cells (MCF-10A), nor normal non-proliferating cells, such as neurons and cardiomyocytes.
