3''-Methoxy-4'',5,7-trihydroxyisoflavone is a derivative of Genistein (G350000); a compound that exhibits specific inhibitory activity against tyrosine kinases, including autophosphorylation of epidermal growth factor receptor kinase (IC50 - 2.6uM). Also inhibits other protein kinases through competitive inhibition of ATP. Inhibits tumor cell proliferation and induces tumor cell differentiation. Produces cell-cycle arrest and apoptosis in Jurat T-leukemia cells. However, it prevents anti-CD3 monoclonal antibody-induced thymic apoptosis. Genistein also inhibits topoisomerase II activity in vitro. Genistein has also been shown to inhibit the action of GABA on recombinant GABAA receptors 2.

ChEBI: 3'-O-methylorobol is a hydroxyisoflavone that is orobol in which the hydroxy group at position 3' has been replaced by a methoxy group. It has been isolated from Crotalaria lachnophora. It has a role as a plant metabolite. It is a methoxyisoflavone and a hydroxyisoflavone. It is functionally related to an orobol.
