Used in research as an inhibitor of poly (ADP-ribose) polymerase (PARP), an enzyme involved in DNA repair. This property makes it valuable in studies related to cancer therapy, particularly in enhancing the effects of DNA-damaging agents like radiation and certain chemotherapeutics. It is also applied in cellular and molecular biology to investigate pathways linked to oxidative stress, inflammation, and apoptosis. Due to its ability to cross cell membranes easily, it is favored in experimental models for modulating PARP activity and studying the consequences of its inhibition.
