NCIt definition : An orally bioavailable inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase
(PARP) with potential antineoplastic activity. Talazoparib selectively binds to PARP
and prevents PARP-mediated DNA repair of single strand DNA breaks via the base-excision
repair pathway. This enhances the accumulation of DNA strand breaks, promotes genomic
instability and eventually leads to apoptosis. PARP catalyzes post-translational ADP-ribosylation
of nuclear proteins that signal and recruit other proteins to repair damaged DNA and
is activated by single-strand DNA breaks.;
