1,5-ISOQUINOLINEDIOL Usage And Synthesis

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.

Chemical Properties

white to off-white solid

Uses

Reagent used in the preparation of PARP inhibitor.

Uses

1,5-Isoquinolinediol can be used as a reagent in the preparation of PARP inhibitor.

Definition

ChEBI: An isoquinolinol that is isoquinoline in which the hydrogens at positions 1 and 5 are replaced by hydroxy groups.

General Description

A potent inhibitor of poly(ADP-ribose) polymerase (PARP; IC₅₀ = 390 nM). Reported to partially block SNAP (CN 487910)- induced cell death in SH-SYSY human neuroblastoma cells.
