5,7-DIHYDROXY-3-METHOXY-2-(4-METHOXY-PHENYL)-CHROMEN-4-ONE Chemical Properties,Uses,Production

Uses

Ermanin is a useful research chemical used in HIV-1 integrase inhibition. Ermanin exhibits actioxidant properties against peroxyl and hydroxyl radicals.

Definition

ChEBI: 3,4'-dimethylkaempferol is a dimethoxyflavone that is kaempferol in which the hydroxy groups at position 3 and 4' have been replaced by methoxy groups. It is a component of bee glue and isolated from several plant species including Tanacetum microphyllum. It has a role as an anti-inflammatory agent, an antimycobacterial drug, an apoptosis inducer, an antineoplastic agent and a plant metabolite. It is a dihydroxyflavone and a dimethoxyflavone. It is functionally related to a kaempferol.

IC 50

iNOS; Bacterial; COX-2
