Purpurogallin 是一种从栎属植物中提取的天然酚，具有显著的黄嘌呤氧化酶抑制作用，其IC50=0.2 μM，具有抗氧化和抗炎作用。

Purpurogallin is a naturally phenol extracted from the plants of Quercus spp. It has effective xanthine oxidase inhibitory activity (IC50: 0.2 μM). Purpurogallin also has antioxidant and anti-inflammatory effects.

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. Purpurogallin (50 or 100 μM; 7 or 25 hours; BV2 murine microglial cells) treatment decreases 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].

By the dual effect of inhibiting IL-6 and TNF-α mRNA expression and reducing HMGB1 protein and mRNA expression, Purpurogallin (100-400?μg/kg; intraperitoneal injection; for 48 or 72 hours; male Sprague-Dawley rats) exerts its neuroinflammation effect [2].
