Abstract
Over activation of c-Met tyrosine kinase is known to promote tumorigenesis and metastasis, as well as to cause therapeutic resistance. Herein we describe the design, synthesis and biological activities of novel, ATP-competitive, c-Met tyrosine kinase inhibitors that are members of the 6-aryl-2-(3-(heteroarylamino)benzyl)pyridazinone family. A structure-activity relationship (SAR) study of these substances led to identification of pyridazinone 19 as a highly selective and potent c-Met tyrosine inhibitor, which displays favorable pharmacokinetic properties in mice and significant antitumor activity against a c-Met driven EBC-1 tumor xenograft.
