What is 5-METHOXYFLAVONE?

The Uses of 5-METHOXYFLAVONE

5-Methoxyflavone is a flavenoid and dietary derived inhibitor of cell proliferation.

Definition

ChEBI: 5-Methoxyflavone is an ether and a member of flavonoids.

Biological Activity

5-Methoxyflavone, a flavonoid, is an inhibitor of DNA polymerase-beta and a neuroprotectant against beta-amyloid toxicity. Possesses central nervous system sedative effect by regulating ionophilic GABAA receptors.

in vitro

5-Methoxyflavone (compound 1) is identified as a candidate compound endowed with the ability to inhibit DNA pol-β in multiple and to prevent cell-cycle initiation and subsequent neuronal apoptosis in Aβ-challenged primary neuronal cultures. It (10-30 μM) is able to significantly enhance toxicity of MMS on 92TAg cells. 5-Methoxyflavone (1 or 10 μM) significantly reduces polymerase activity on a gapped substrate.
5-Methoxyflavone (5-MF , 0-100 μg/mL) results in a time dependent reduction in the levels of antiapoptotic proteins cFLIP, Mcl-1 and an increase in the proapoptotic protein BAX. 5-MF induces both TRAIL-R1(DR4) and TRAIL-R2 ( DR5) in a time-dependent manner.

in vivo

5-Methoxyflavone (100, 150 mg/kg, ip) significantly decreases the latency time to loss of righting reflex. It (50, 100 and 150 mg/kg, ip) exhibits a significant and dose decreases -dependent reduction in the spontaneous locomotor activity. 5-Methoxyflavone (50, 100 mg/kg, ip) reduces the rearing response. 5-Methoxyflavone (100, 125 and 150 mg/kg, ip) completely abolishesed the grooming response similar to diazepam treated animals.
