Abstract
Chemical strategies to mitigate cytochrome P450-mediated
bioactivation of novel 2,7-disubstituted pyrrolo[2,1-<i>f</i>][1,2,4]triazine ALK inhibitors are described along with synthesis
and biological activity. Piperidine-derived analogues showing minimal
microsomal reactive metabolite formation were discovered. Potent,
selective, and metabolically stable ALK inhibitors from this class
were identified, and an orally bioavailable compound (<b>32</b>) with antitumor efficacy in ALK-driven xenografts in mouse models
was extensively characterized
