Parp inhibitor cell ic50
http://www.parp-inhibitors.com/ WebOlaparib is a targeted drug called a PARP inhibitor. PARP is a protein that helps damaged cells to repair themselves. Olaparib stops PARP working. Some cancer cells rely on PARP to keep their DNA healthy. This includes cancer cells with a change in the BRCA genes. So, when olaparib stops PARP from repairing DNA damage, the cancer cells die.
