Application

DPQ has been used as a PARP1 (poly(ADP-ribose) polymerase 1) inhibitor in in vivo studies to determine the loss of γ-H2AX (H2A histone family member X) upon irradiation.

Biochem/physiol Actions

3,4-Dihydro-5-[4-(1-piperidinyl)butoxyl]-1(2H)-isoquinolinone (DPQ) is known to decrease the PARP 1 (poly(ADP-ribose) polymerase 1) mediated apoptosis under the influence of ischemia. It is considered as more effective inhibitor than the traditionally used PARP1 inhibitor 3-aminobenzamide.
DPQ is a very potent poly(ADP-ribose) polymerase (PARP) inhibitor.

Cell death induced by excessive glutamate receptor overactivation, excitotoxicity, has been implicated in several acute and chronic neurological disorders. While numerous studies have demonstrated the contribution of biochemically and genetically activated cell death pathways in excitotoxic injury, the factors mediating

A series of dihydroisoquinolinones, formally rigid analogs of 3-substituted benzamides, and a series of 2,3-disubstituted benzamides were synthesized and evaluated as inhibitors of poly(ADP-ribose) polymerase. The results indicated that the orientation of the amide with respect to the substituent on
