生产及用途

生物活性

Purpurogallin 是从栎属植物中提取的天然酚，具有强的黄嘌呤氧化酶 (Xanthine Oxidase) 抑制活性，其 IC50 为 0.2 µM。Purpurogallin 具有抗氧化和抗炎作用。

靶点

IC50: 0.2 µM (xanthine oxidase)

体外研究

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.
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.

RT-PCR

Cell Line:	BV2 murine microglial cells
Concentration:	50 or 100 µM
Incubation Time:	7 or 25 hours
Result:	Attenuated 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.

Western Blot Analysis

Cell Line:	BV2 murine microglial cells
Concentration:	100 µM
Incubation Time:	75 minutes, 90 minutes, 120 minutes
Result:	Suppressed the phosphatidylinositol 3-kinase/Akt and mitogen-activated protein kinase signaling pathways.

体内研究

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.

Animal Model:	Fifty-four male Sprague-Dawley rats (250-350 g) with subarachnoid hemorrhage (SAH)
Dosage:	100 μg/kg, 200 μg/kg, 400 μg/kg
Administration:	Intraperitoneal injection; for 48 or 72 hours
Result:	Dose-dependently reduced HMGB1 protein expression. High dose reduced TNF-α and HMGB1 mRNA levels.
