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]
