Abstract

The invention relates to novel application of massoia lactone and 5-hydroxy-2-caproleic acid. An animal model test proves that for a CCL4 induced mouse hepatic fibrosis and liver cirrhosis model, after massoia lactone or 5-hydroxy-2-caproleic acid is used for intervention, the abnormal liver function can be remarkably improved, the serum aspartate amino transferase, glutamic-pyruvic transaminase and the total bilirubin level are lowered, the content of hepatic tissue hydroxyproline is decreased, hepatic stellate cell activation is inhibited, the type I collagen expression is reduced, and liver tissue collagen deposition is restrained; for a HepG-2 nude-mouse transplanted tumor model, after massoia lactone or 5-hydroxy-2-caproleic acid is used for intervention, increase of the weight and size of transplantation tumors can be remarkably inhibited. Accordingly, the two compounds can be used for preparing liver fibrosis, liver cirrhosis and liver cancer resistance drugs.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of massoia lactone and 5-hydroxy-2-decenoic acid in the preparation of drugs for resisting liver fibrosis, chronic liver disease, liver cirrhosis and liver cancer. Background technique [0002] The Chinese name of Massoia lactone is 5,6-dihydro-6-pentyl-2H-pyran-2-one (see the chemical structure figure 1 ), present in Masoya osmanthus oil, fermented Cordyceps mycelia, liquor, wine, sweet-scented osmanthus and sugar cane molasses, and has antibacterial, anti-infective, and immune-regulating effects. In addition, because of its creamy, coconut, spicy, and celery aroma, it is also often used as a precious spice for butter, cream, vanilla, peach, almond, fruit, nut, and tobacco flavor formulations. 5-Hydroxy-2-decenoic acid is the product after the hydrolysis of the lactone ring of massoia lactone (chemical structure see figure 1 ), which are only reported in the s...
