生物活性

Nepetin (6-Methoxyluteolin) is a natural flavonoid isolated from Eupatorium ballotaefolium HBK with potent anti-inflammatory activities. Nepetin inhibits IL-6, IL-8 and MCP-1 secretion with IC50 values of 4.43 μM, 3.42 μM and 4.17 μM, respectively in ARPE-19 cells[1][2].

体外研究
(In Vitro)

Pretreatment with Nepetin dose-dependently inhibited IL-6, IL-8 and MCP-1 secretion with IC50 values of 4.43, 3.42 and 4.17 μM, respectively[1].
Nepetin (2.5-10 μM; 25 hours; ARPE-19 cells) treatment suppresses IL-1β-induced cytokine (IL-6, IL-8 and MCP-1) expression at mRNA level in ARPE-19 cells[1].
Nepetin (2.5-10 μM; 1.5 hours; ARPE-19 cells) treatment dose-dependently inhibits phosphorylation of IKKα/β and IκBα, and nuclear translocation of p65. Nepetin decreases the level of phosphorylated ERK1/2, JNK and p38 MAPK in activated ARPE-19 cells[1].
