Altered expression or hyperactivation of anaplastic lymphoma kinase (ALK), as a consequence of translocations or point mutations, is one of the main oncogenic drivers in non-small cell lung cancer. Using structure-based design and in vitro enzyme assays, we identified 3-heteroarylcoumarin as a new template for the development of novel fluorescent ALK inhibitors. Molecular simulation provided structural insights for the design of 3-heteroarylcoumarin derivatives, which were easily prepared through efficient synthetic approaches including direct C-H cross coupling. Importantly, these coumarin-based ALK inhibitors can be tracked using microscopy techniques: we illustrated the use of the most potent compound in this series, 5a, (ALK/IC50 = 0.51 μM, λemi = 500 nm, φF = 0.29) to monitor its subcellular distribution pattern by confocal fluorescence microscopy.

A Pd-catalyzed direct cross-coupling of 3-bromocoumarins with heteroarenes provided an efficient route to synthesizing 3-heteroarylcoumarins. The reaction scope for the transformation was fairly broad, affording modest to good yields of various 3-heteroarylcoumarin scaffolds, which are privileged structures and prevalent motifs in many biologically active compounds and fluorophores.
