Formula: C8H10N2Os

Description: DR2313 is a potent, selective, competitive and brain-penetrant inhibitor of poly(ADP-ribose) polymerase (PARP), with IC50s of 0.20 μM and 0.24 μM for PARP-1 and PARP-2, respectively. DR2313 exhibits neuroprotective effects on ischemic injuries in vitro and in vivo[1][2].
Target: PARP-1:0.20 μM (IC50) PARP-2:0.24 μM (IC50)
In Vivo: DR2313 (3-10 mg/kg i.v. bolus or infusion for 6 h) significantly reduces the cortical infarct volume in both permanent and transient focal ischemia models in rats[1]. Animal Model: Male Wistar rats (220-300 g) with permanent MCA occlusions (pMCAos) and transient MCA occlusions (tMCAos)[1] Dosage: 3, 10 mg/kg Administration: I.v. bolus and i.v. infusion for 6 h beginning 5 min before the onset of ischemia Result: Reduced the infarct volume in a dose-dependent manner in pMCAo and tMCAo model.
In Vitro: DR2313 (0.016-16.4 μM; 30 min) inhibits poly(ADP-ribosyl)ation reaction in nuclear extracts of rat brain, with a Ki of 0.23 μM[1]. DR2313 shows more powerful inhibition of the poly(ADP-ribosyl)ation in the nuclear extracts of the rat brain (IC50=0.20 μM) than 3AB (35.4 μM), PND (0.56 μM), DIQ (2.96 μM), and DPQ (0.96 μM)[1]. DR2313 (1-100 μM; 10 min) shows a weak inhibition of the mono(ADP-ribosyl)ation in a concentration-dependent manner (IC50=59 μM)[1]. DR2313 (0.1-30 μM; pretreated for 30 min) reduces hydrogen peroxide (500 μM; 4 h) or glutamate (1 mM; 30 min) induced excessive formation of poly(ADP-ribose) and cell death[1].
