摘要

Anaplastic lymphoma kinase (ALK) is transmembrane receptor tyrosine kinase, with oncogenic variants that have been implicated in ALCL, NSCLC and other cancers. Screening of a VEGFR2-biased kinase library resulted in identification of 1 which showed cross-reactivity with ALK. SAR on the indole segment of 1 showed that a subtle structural modification (the ethoxy group of 1 changed to a benzyloxy to generate 5a) enhanced ...
