Application

3′,4′-Dimethoxyflavone has been used in urease inhibition assay.

Biochem/physiol Actions

3′,4′-Dimethoxyflavone is a flavone compound, which has the ability to prevent the production and accumulation of poly (ADP-ribose) (PAR) polymer. It guards against N-methyl-D-aspartate (NMDA) toxicity in cortical neurons. 3′,4′-Dimethoxyflavone is a member of the class of plant-derived polyphenolic flavonoids. It is known to have antioxidant, anti-cancer, anti-inflammatory, anti-atherogenic, hypolipidemic and neuroprotective or neurotrophic effects.
3′,4′-dimethoxyflavone is a competitive antagonist of the AhR that inhibits AhR-mediated induction of CYP1A1, and also displays antiestrogen activity in breast tumor cell lines. The compound blocks transformation of the cytosolic AhR complex, and formation of nuclear AhR complexes.

There is increasing evidence of the involvement of the tryptophan metabolite kynurenine (KYN) in disrupting osteogenesis and contributing to aging-related bone loss. Here, we show that KYN has an effect on bone resorption by increasing osteoclastogenesis. We have previously reported

Exposure to aristolochic acid I (AAI) can lead to aristolochic acid nephropathy (AAN), Balkan endemic nephropathy (BEN) and urothelial cancer. The induction of hepatic CYP1A, especially CYP1A2, was considered to detoxify AAI so as to reduce its nephrotoxicity. We previously
