Fused aza-heterocyclic amide compound and use thereof

Provided in the present invention is a compound as represented by formula (I) or a tautomer, a stereoisomer, a solvate, a nitrogen oxide, a prodrug, an isotope derivative or a pharmaceutically acceptable salt thereof. The compound exhibits an excellent kinase inhibitory activity against a variety of kinases (such as TRK, ALK and ROS1) and mutants thereof, in particular TRK and a mutant form thereof. An in vitro cell inhibitory activity test and an in vivo anti-tumor model test show that the compounds have a strong inhibitory effect on a variety of cells containing TRK mutations and tumors, have a good safety, and have a good clinical value as drugs.
