  • Patent number: 10266518
    Abstract: The present invention provides compounds of Formula I, for modulating receptor kinase activity, particularly ephrin and EGFR, and methods of treating diseases mediated by receptor kinase activity utilizing the compounds and pharmaceutical compositions thereof. Diseases mediated by receptor kinase activity include, but are not limited to, diseases characterized in part by abnormal levels of cell proliferation (i.e. tumor growth), programmed cell death (apoptosis), cell migration and invasion and angiogenesis associated with tumor growth. Compounds of the invention include “spectrum selective” kinase modulators, compounds that inhibit, regulate and/or modulate signal transduction across subfamilies of receptor-type tyrosine kinases, including ephrin and EGFR.
