1,5,7,8-TETRAHYDRO-2-METHYL-4H-THIOPYRANO[4,3-D]PYRIMIDIN-4-ONE Chemical Properties,Usage,Production

Uses

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].

Biological Activity

Potent, competitive inhibitor of poly(ADP-ribose) polymerase (PARP) (IC 50 values are 0.20 and 0.24 μ M for PARP-1 and PARP-2 respectively). Neuroprotective; reduces neuronal cell death in models of cerebral ischemia in vivo and in vitro . Brain penetrant.

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.

IC 50

PARP-1: 0.20 μM (IC₅₀); PARP-2: 0.24 μM (IC₅₀)
