Trapping Poly(ADP-Ribose) Polymerase

The Journal of Pharmacology and Experimental Therapeutics, 2015
Recent findings indicate that a major mechanism by which poly(ADP-ribose) polymerase (PARP) inhibitors kill cancer cells is by trapping PARP1 and PARP2 to the sites of DNA damage. The PARP enzyme-inhibitor complex "locks" onto damaged DNA and prevents DNA repair, replication, and transcription, leading to cell death.

Poly(ADP-Ribose) Polymerase Inhibitors

Current Medicinal Chemistry, 2003
Poly(ADP-ribose) polymerase-1 (PARP-1) is the principal member of the PARP enzyme family consisting of PARP-1 and several recently identified novel poly(ADP-ribosyl)ating enzymes. PARP-1 functions as a DNA damage sensor and signalling molecule. Upon binding to DNA breaks, activated PARP cleaves NAD(+) into nicotinamide and ADP-ribose and polymerizes ...
