orobol

Orobol (3',4',5,7-tetrahydroxy-isoflavon) is an inhibitor of tyrosine-specific protein kinase and phosphatidylinositol turnover. Orobol inhibits PI3K isoforms with IC50s of 3.46-5.27 μM for PI3K α β γ K δ. Orobol exhibits anti-skin-aging and anti-obesity effects.

3'-O-Methylorobol exhibits moderate antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl free radical scavenging assay, it also exerts potential analgesic properties. 3'-O-Methylorobol can increase osteoblast differentiation.

6,8-Diprenylorobol possesses weaker anti-H. pylori activity, it may be a useful chemopreventive agent for peptic ulcer or gastric cancer in H. pylori-infected individuals.

7,3'-Di-O-Methylorobol is a naturally occurring flavonoid found in Sophora japonica that is used in biochemical experiments and organic synthesis.
