An orally available inhibitor of multiple kinases, including the receptor tyrosine kinase anaplastic lymphoma kinase (ALK) and c-ros oncogene 1 (ROS1), with potential antineoplastic activity. Upon oral administration, alkotinib binds to and inhibits the wild-type, point mutations and fusion proteins of ALK and ROS1. Inhibition of these kinases leads to the disruption of downstream signaling pathways and the inhibition of proliferation in tumor cells which these kinases are overexpressed, rearranged or mutated.
