7-hydroxyflavone belongs to the flavone subgroup of flavonoids. It is a potent inhibitor of 20alpha-hydroxysteroid dehydrogenase (AKR1C1), aromatase (cytochrome P450 19; CYP19), aldo-keto reductases AKR1B10 and AKR1B1. It can inhibit LPS-induced inflammation via attenuating the production of NO, PGE2, TNF-alpha and IL-6, indicating that it may be lead compound for developing anti-inflammatory agent. 7-hydroxyflavone may serve as potential protective agents in the treatment of patients with chronic EV71 infection.

In Vitro Use Guide

Renal proximal tubule (NRK52E) cells were pre-treated with 20 uM 7-Hydroxyflavone overnight prior to treatment with 200 uM nicotine and cell viability was determined 24 hours later. Nicotine significantly decreases cell viability, which was prevented by pretreatment with 7-Hydroxyflavone.
