Sumario: | [Image: see text] The anaplastic lymphoma kinase (ALK) is abnormally expressed and hyperactivated in a number of tumors and represents an ideal therapeutic target. Despite excellent clinical responses to ALK inhibition, drug resistance still represents an issue and novel compounds that overcome drug-resistant mutants are needed. We designed, synthesized, and evaluated a large series of azacarbazole inhibitors. Several lead compounds endowed with submicromolar potency were identified. Compound 149 showed selective inhibition of native and mutant drug-refractory ALK kinase in vitro as well as in a Ba/F3 model and in human ALK+ lymphoma cells. The three-dimensional (3D) structure of a 149:ALK-KD cocrystal is reported, showing extensive interaction through the hinge region and the catalytic lysine 1150. |
