The invention discloses a preparation method of alpha-ketoisovaleric acid in an anti-
hepatic fibrosis drug, and relates to the technical field of
hepatic fibrosis treatment
drug development, and the preparation method comprises the following steps: mixing alpha-ketoisovaleric acid with pharmaceutic adjuvants to prepare a pharmaceutically acceptable
dosage form; the dosage of the alpha-ketoisovaleric acid is determined based on the pharmacological activity of the alpha-ketoisovaleric acid in the concentration range of 50 mu M to 200 mu M, wherein the alpha-ketoisovaleric acid can inhibit
hepatic stellate cell activation induced by a
transforming growth factor-beta; an endogenous
metabolite alpha-ketoisovaleric acid is applied to preparation of an anti-
hepatic fibrosis medicine, and based on the pharmacological activity of the alpha-ketoisovaleric acid for specifically inhibiting activation of TGF-beta induced hepatic stellate cells at the concentration of 50-200 mu M, a novel anti-hepatic
fibrosis preparation which is high in safety, wide in
therapeutic window and free of
liver and kidney accumulation risk is developed. The
medicine is not only suitable for treating hepatic
fibrosis caused by various causes such as non-
alcoholic fatty liver disease,
viral hepatitis,
alcoholic liver disease and
drug-induced
liver injury, but also meets the requirements of early intervention and severe treatment through reasonable
dosage form design and administration
route selection.
