Description
APG-2449 is an orally available kinase inhibitor of the receptor tyrosine kinase anaplastic lymphoma kinase (ALK), focal adhesion kinase (FAK) and the receptor tyrosine kinase C-ros oncogene 1 (ROS1), with potential antineoplastic activity. Upon administration, ALK/FAK/ROS1 inhibitor APG-2449 selectively binds to and inhibits ALK, FAK and ROS1 kinases. The inhibition leads to disruption of ALK-, FAK- and ROS1-mediated signal transduction pathways and eventually inhibits tumor cell growth in ALK-, FAK- and ROS1-overexpressing tumor cells. ALK belongs to the insulin receptor superfamily and plays an important role in nervous system development; its dysregulation and gene rearrangements are associated with a variety of tumors. The cytoplasmic tyrosine kinase FAK, a signal transducer for integrins, is upregulated and constitutively activated in various tumor types; it plays a key role in tumor cell migration, proliferation, survival, and tumor angiogenesis. ROS1, overexpressed in certain cancer cells, plays a key role in cell growth and survival of cancer cells.
Uses
APG-2449 is an orally active inhibitor of ALK/ROS1/FAK. APG-2449 exerts potent and durable antitumor activity in human non-small-cell lung cancer (NSCLC) and ovarian tumor models.
