Definitions

  • the invention relates to a benzopyrazole compound and its intermediate, preparation method and application.
  • Wnt signaling pathway plays a role in regulating the inducing interaction of growth and differentiation, and also plays a role in the homeostasis maintenance of tissue integrity after embryos.
