Molecular Weight:

300.26 Diosmetin is a bioflavonoid found in spearmint, oregano, and many other plants.

Biological Activity

Diosmetin inhibits 3H-dopamine uptake in neuroblastoma cells, as well as
in small-cell lung carcinoma cells, which is be responsible for the
increased vascular tone observed in vivo after treatment with Diosmetin.


Moreover, Diosmetin also removes iron from iron-loaded
hepatocytes revealed a good relationship between this iron-chelating
ability and the cytoprotective effect. Other studies
proves that Diosmetin is a cytochrome P450 Inhibitor, thus inhibiting
carcinogen activation and and causing pharmacokinetic interactions with
co-administered drugs metabolized.

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Rat dose (mg/kg) = mouse dose (22.4 mg/kg) × mouse Km(3) = 11.2 mg/kg
