Because of the critical roles of aberrant signaling in cancer, both c-MET and ALK receptor
tyrosine kinases are attractive oncology targets for therapeutic intervention. The cocrystal
structure of 3 (PHA-665752), bound to c-MET kinase domain, revealed a novel ATP site
environment, which served as the target to guide parallel, multiattribute drug design. A novel
2-amino-5-aryl-3-benzyloxypyridine series was created to more effectively make the key
interactions achieved with 3. In the novel series, the 2-aminopyridine core allowed a 3 …
Because of the critical roles of aberrant signaling in cancer, both c-MET and ALK receptor tyrosine kinases are attractive oncology targets for therapeutic intervention. The cocrystal structure of 3 (PHA-665752), bound to c-MET kinase domain, revealed a novel ATP site environment, which served as the target to guide parallel, multiattribute drug design. A novel 2-amino-5-aryl-3-benzyloxypyridine series was created to more effectively make the key interactions achieved with 3. In the novel series, the 2-aminopyridine core allowed a 3-benzyloxy group to reach into the same pocket as the 2,6-dichlorophenyl group of 3 via a more direct vector and thus with a better ligand efficiency (LE). Further optimization of the lead series generated the clinical candidate crizotinib (PF-02341066), which demonstrated potent in vitro and in vivo c-MET kinase and ALK inhibition, effective tumor growth inhibition, and good pharmaceutical properties.
