It has been shown that Compound 1 unexpectedly and potently inhibits TIE2 kinase, and that Compound 1 inhibits drug resistance mechanisms in both the tumor and in the surrounding microenvironment through balanced inhibition of TIE2, MET, and VEGFR2 kinases. Thus, Compound 1 provides a single therapeutic agent able to address multiple hallmarks of cancer by inhibiting TIE2, MET, and VEGFR2 kinases in the tumor microenvironment [Hanahan 2011]. Through its balanced inhibitory potency vs TIE2, MET, and VEGFR2, Compound 1 provides an agent which inhibits three major tumor (re)vascularization and resistance pathways (ANG, HGF, VEGF) and blocks tumor invasion and metastasis. Compound 1 exhibits anti-tumor activity alone and in combination with other targeted agents or chemotherapy. |
