The compounds can be used as a Hedgehog signal conduction inhibitor applied to multiple medical applications.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to a class of heterocyclic amine Hedgehog signal pathway inhibitors with a structure of formula (I), and the medical application of these compounds. Background technique [0002] The Hedgehog (Hh) signaling pathway is a very important pathway that controls the growth and survival of cells in mammals. During embryonic development, the Hh pathway plays an important role in cell differentiation and proliferation, organ formation, etc.; in adults, the Hh pathway is closely related to tissue wound repair and stem cell maintenance. The Hh signal transduction pathway is mainly composed of secreted glycoprotein ligand Hh, transmembrane protein receptor Patched-1 (Ptch1), transmembrane protein Smoothened (Smo), and nuclear transcription factor Gli protein. Hh signal transduction is a very complicated process: when there is no Hh signal, Ptch1 binds to Smo, inhibits the activity of Smo, and the tr...
