描述 | Poly(ADP-ribose) polymerases (PARPs) are a relatively large family of enzymes that catalyse the transfer of ADP-ribose units from NAD+ to acceptor proteins. They are involved in key cellular functions including DNA repair, telomere integrity, gene expression, cell division, cell survival and cell death. UPF 1069 is a specific PARP2 inhibitor with IC50 of 0.3 M, which is about 27 times more selective than PARP1. 10 µM UPF-1069 was able to reduce PARP activity by 80% in PARP-1-deficient fibroblasts, but only slightly inhibited the enzymic activity in wild-type fibroblasts. The effect of UPF-1069 on organotypic hippocampal slices exposed to 20 min OGD (oxygen-glucose deprivation) was tested at concentrations (0.1–1 µM) selectively acting on PARP-2. It significantly enhanced CA1 hippocampal damage. UPF-1069 displayed a significant neuroprotective activity both at a concentration (1 µM) selectively acting on PARP-2 and at a concentration (10 µM) that inhibits both PARP-1 and PARP-2 activities[2]. |
