This invention belongs to the field of biomedicine, specifically relating to the application of APOL2 (Apolipoprotein L2) inhibitors in the preparation of products for treating liver fibrosis. The inventors isolated a series of natural tetrodopane-type diterpenes from *Euphorbia pekinensis*, a plant in the Euphorbiaceae family. Anti-liver fibrosis-related activity tests on this series of diterpenes revealed that they significantly inhibited the expression of fibronectin, type I collagen, and α-smooth muscle actin in LX-2 cells. In animal studies, their therapeutic effect was superior to that of pirfenidone, a phase II clinical trial drug for treating liver fibrosis, and they showed no significant toxicity. Mechanistic studies showed that TD1 is an APOL2 inhibitor, and knocking out APOL2 protein in vivo can alleviate the progression of liver fibrosis. In summary, this series of tetrodopane-type diterpenes, especially TD1, shows promise as a candidate drug for treating liver fibrosis and provides a new target for researching novel drugs for treating liver fibrosis.
