Biological Activity

[Description]:

3-Aminobenzamide is a potent inhibitor of PARP with IC50 of appr 50 nM in CHO cells, and acts as a mediator of oxidant-induced myocyte dysfunction during reperfusion.

[Target]

PARP:50 nM (IC50)

[In Vitro]

3-Aminobenzamide (>1 μM) causes more than 95% inhibition of PARP activity without significant cellular toxicity. INO-1001 significantly sensitizes CHO cells by blocking most of the DNA repair occurring between radiation fractions[1]. 3-Aminobenzamide significantly improves endothelial function by enhancing the acetylcholine-induced, endothelium-dependent, nitric oxide mediated vasorelaxation after exposure with 400 μM H2O2[2].

[In Vivo]

In a db/db (Leprdb/db) mouse model, 3-Aminobenzamide ameliorates diabetes-induced albumin excretion and mesangial expansion, and also decreases diabetes-induced podocyte depletion[3]. 3-Aminobenzamide (1.6 mg/kg via intracerebral injection) prevents NAD+ depletion and improves water maze performance after controlled cortical impact (CCI) in mice[4].

[Kinase Assay]

PARP activity is measured with a PARP Activity Assay Kit. This method measures relative PARP activity by determining the level of incorporation of 3H-NAD into trichloroacetic acid (TCA) precipitable material in the presence of sheared genomic DNA, which activates PARP. The reaction mixture is added directly to washed cultures in 12-well culture plates and the reaction is allowed to proceed for 60 minutes at 37°C before the cells are removed mechanically, transferred to a microcentrifuge tube, and precipitated with ice-cold 5% TCA.

[Animal admin]

Male db/db (Leprdb/db) mice, together with nondiabetic control db/m mice on C57BLKs/J background, are used. INO-1001 and PJ-34 treatment are initiated at 5 weeks of age. In sterile water that is sweetened with NutraSweet, 4.8 g/L 3-Aminobenzamide and 2.4 g/L PJ-34 is dissolved. Control animals receive sweetened water only. The average inhibitor consumption is 60 mg/kg 3-Aminobenzamide and 30 mg/kg PJ-34.
