PARP inhibitor

Model of the inhibitor olaparib (dark gray) occupying the NAD+-binding site of PARP1. From PDB: 5DS3​.

PARP inhibitors are a group of pharmacological inhibitors of the enzyme poly ADP ribose polymerase (PARP).

They are developed for multiple indications, including the treatment of heritable cancers.[1] Several forms of cancer are more dependent on PARP than regular cells, making PARP (PARP1, PARP2 etc.) an attractive target for cancer therapy.[2][3][4][5] PARP inhibitors appear to improve progression-free survival in women with recurrent platinum-sensitive ovarian cancer, as evidenced mainly by olaparib added to conventional treatment.[6]

In addition to their use in cancer therapy, PARP inhibitors are considered a potential treatment for acute life-threatening diseases, such as stroke and myocardial infarction, as well as for long-term neurodegenerative diseases.[7]
