An orally available crystalline formulation of genistein, a soy-derived isoflavone and phytoestrogen with potential antineoplastic, chemosensitizing, and antioxidant activities. Similar to genistein, crystalline genistein formulation AXP107-11 increases expression of phosphatase and tensin homolog (PTEN), which deactivates protein kinase Akt and mitogen-activated protein kinases (MAPK1 and 3; ERK2 and 1), thereby disrupting PI3K/Akt signal transduction and inducing apoptosis. This agent also induces antioxidant enzymes through AMP-activated protein kinase (AMPK) activation, inhibits NF-kB activation and decreases inflammation response, thereby sensitizing tumors to chemotherapy. Compared to genistein itself, this crystalline formulation shows improved solubility and bioavailability. Check for active clinical trials using this agent.
