Background

7,4′-Di-O-methylapigenin is a flavonoid that has been found in T. diffusa and has diverse biological activities.^1,2,3,4,5 It inhibits monoamine oxidase B (MAO-B) but not MAO-A (IC₅₀s = 0.198 and >100 ?M, respectively), as well as p38α MAPK but not JNK3 (IC₅₀s = 27.8 and >100 ?M, respectively).^1,2 7,4′-Di-O-methylapigenin inhibits the production of nitric oxide (NO) in LPS-stimulated RAW 264.7 macrophages (IC₅₀ = 24.5 ?M).³ It reduces the growth of C. albicans when used at a concentration of 45 ?g/ml.⁴ 7,4′-Di-O-methylapigenin inhibits carrageenan-induced edema in rats (ED₂₅ = 75 mg/kg).⁵
