产品介绍
5-O-Demethylnobiletin (5-Demethylnobiletin) 5-O-去甲肾上腺素,一种从黄芪中分离出的多甲氧基黄酮,是 5-LOX 的直接抑制剂 (IC50=0.1 μM),不影响 COX-2 的表达。5-O-Demethylnobiletin (5-Demethylnobiletin) 5-O-去甲肾上腺素具有抗炎活性,抑制大鼠中性粒细胞中白三烯 B (4)(LTB4) 的形成和人嗜中性粒细胞中弹性蛋白酶的释放,IC50 值为0.35 μM.5-O-Demethylnobiletin (5-Demethylnobiletin) 5-O-去甲肾上腺素通过激活 MAPK/ERK-,PKC- 和 PKA 依赖性信号传导途径促进神经发生。

Background:

5-O-Demethylnobiletin (5-Demethylnobiletin), a polymethoxyflavone isolated from Sideritis tragoriganum, is a direct inhibition of 5-LOX (IC50=0.1 μM), without affecting the expression of COX-2. 5-O-Demethylnobiletin (5-Demethylnobiletin) has anti-inflammatory activity, inhibits leukotriene B (4)(LTB4) formation in rat neutrophils and elastase release in human neutrophils with an IC50 of 0.35 μM[1].5-O-Demethylnobiletin (5-demethylnobiletin) promotes neuritogenesis through the activation of MAPK/ERK-, PKC-, and PKA-dependent signaling pathways[2]. IC50: 0.1 μM (Lox 5); 0.35 μM (LTB4) (5-O-Demethylnobiletin)[1]
