The present invention relates to the pharmaceutical composition for prevention and treatment of liver diseases containing pyrazolopyrimidine derivative as an active ingredient. According to the present invention, pyrazolopyrimidine derivative has an excellent effect on inhibiting collagen synthesis in hepatic stellate cells and acts directly on the portal vein. Particularly, it may increase the diameter and the amount of blood flow of the portal vein, and finally decrease the pressure thereof.
