INO-1001 can potently inhibits PARP with IC50 of 50 nM.. Inhibition of PARP activity by INO-1001 significantly improves endothelial function by enhancing the acetylcholine-induced, endothelium-dependent, nitric oxide mediated vasorelaxation after exposure with 400 uM H2O2.
In vivo
In a db/db (Leprdb/db) mouse model, INO-1001 ameliorates diabetes-induced albumin excretion and mesangial expansion, and also decreases diabetes-induced podocyte depletion.
