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].
