FRAX1036 is a selective inhibitor of p21-activated kinase 1 (PAK1), a serine/threonine kinase downstream of Rac1 and Cdc42 that is involved in tumorigenesis. It can induce apoptosis in breast cancer cells and has been shown to potentiate the activity of the microtubule stabilizing agent, docetaxel . Disruption of PAK1 via FRAX1036 has been used to inhibit oncogenic KRAS signaling in non-small cell lung cancer cells.
