• PubMed Abstract: 
  

  A series of N-(3-((1H-pyrazolo[3,4-b]pyridin-5-yl)ethynyl)benzenesulfonamides were designed as the first class of highly selective ZAK inhibitors. The representative compound 3h strongly inhibits the kinase activity of ZAK with an IC ₅₀ of 3.3 nM and dose-dependently suppresses the activation of ZAK downstream signals in vitro and in vivo, while it is significantly less potent for the majority of 403 nonmutated kinases evaluated. Compound 3h also exhibits orally therapeutic effects on cardiac hypertrophy in a spontaneous hypertensive rat model.
