WebPARP inhibitors can have significant interactions with other drug classes depending on their unique pharmacological properties. The specific interactions for each PARP inhibitor are … Web3.3 Poly ADP-ribose polymerase 1 (PARP-1) PARP1 is a critical protein in DNA repair that post translationally modifies itself and other proteins by adding ADP-ribose units to them (Ray Chaudhuri & Nussenzweig, 2024 ). PARP1 has roles in both single strand break repair and double strand break repair.

WebPARP inhibitors act by trapping PARP on DNA, which is key as it presents a physical obstacle to the replication machinery. To resolve the PARP-DNA interaction, HRR is necessary. Therefore, in HRR-deficient cancer cells, trapped PARP results in replication fork collapse and finally cell death.
