Purpurogallin is a naturally phenol extracted from the plants of Quercus spp, has potent xanthine oxidase (XO) inhibitory activity with an IC50 of 0.2 µM. Purpurogallin has antioxidant and anti-inflammatory effects[1][2][3].
Purpurogallin (50 or 100 µM; 7 or 25 hours; BV2 murine microglial cells) treatment attenuates the production of pro-inflammatory cytokines, including interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) by suppressing their mRNA and protein expression in LPS-stimulated BV2 microglial cells[1].Purpurogallin (100 µM; 75-120 minutes; BV2 murine microglial cells) exhibits anti-inflammatory properties by suppressing the phosphatidylinositol 3-kinase/Akt and mitogen-activated protein kinase signaling pathways in LPS-stimulated BV2 microglial cells[1]. RT-PCR[1] Cell Line: BV2 murine microglial cells
Purpurogallin (100-400 μg/kg; intraperitoneal injection; for 48 or 72 hours; male Sprague-Dawley rats) exerts its neuroinflammation effect through the dual effect of inhibiting IL-6 and TNF-α mRNA expression and reducing HMGB1 protein and mRNA expression[2]. Animal Model: Fifty-four male Sprague-Dawley rats (250-350 g) with subarachnoid hemorrhage (SAH)[2]
