PX-866

PX-866 is a wortmannin analog that inhibits PI3K, exhibiting anticancer chemotherapeutic and anti-angiogenic activities. PX-866 is currently in clinical trials as a standalone or combination therapy in the treatment of advanced solid tumors. PX-866 inhibits invasion and angiogenesis and induces autophagy in glioblastoma cells. In animal models of cancer, PX-866 inhibits tumor growth and increases survival time. PX-866 also inhibits motility of cancer cells.
