1,5-Isoquinolinediol

Description

The poly(ADP-ribose) polymerases (PARPs) form a family of enzymes with roles in DNA repair and apoptosis. 1,5-Isoquinolinediol is an inhibitor of poly(ADP-ribose) synthetase (PARP1; IC₅₀ = 0.39 μM). It has been used to study the role of PARP1 in both DNA repair and oxidant stress-induced cell death. This compound can be used with cells in culture and in animals.
