CEP-14083 is a potent ALK inhibitor that has shown activity in an NPM ALK–carrying T-cell lymphoma in vitro study. Presumably, this compound binds to the hinge region of the kinase in an ATP-competitive manner. CEP-14083 displays a potent activity against ALK in enzymatic assays (IC50 = 11 nmol L). Further, CEP-14083 is also able to inhibit the insulin receptor at a concentration within a nanomolar range. In a preclinical assay, CEP-14083 showed that, via NPM ALK TK inhibition, it could control the expression of molecules that determine T-cell identity and signaling in lymphoma cells. CEP-14083 has shown preclinical activity in both cell lines and animal models harboring ALK alteration.
2-MT 63 is a novel TIE-2 kinase inhibitor that demonstrates unique and improved kinase selectivity compared to other inhibitors known to interact with TIE-2. 2-MT 63 has a good kinase selectivity profile in enzyme assays with >30-fold selectivity (typically much greater) against the tested kinases. Importantly, the profile includes selectivity against other targets of relevance for angiogenesis (KDR, PDGFR, EPHB4).
