Abstract

The invention relates to a lactone derivative derived from trichoderma citrinoviride and application thereof. The compound contains a molecular skeleton of hetero-oxygen atom pentacyclic lactone, and two methyls on the ring are located at the same side of the molecule. Verified by experiments, the lactone derivative has excellent anti-tumor activity. Besides, the lactone derivative can be applied to preparation of a cell proliferation inhibition drug or an anti-tumor drug and used for anti-tumor research.

Description

technical field [0001] The invention relates to a lactone derivative derived from Trichoderma aurantii and its application. Background technique [0002] In recent decades, during the research and development of new antineoplastic drugs, many natural lactones with anticancer activity have been discovered. Natural lactones with anticancer activity are mostly derived from marine organisms, with unique structures and novel mechanisms of action, which can not only provide lead compounds, but also provide a basis for the discovery of new targets. In addition, Iejimalides, anterior dinolides, and spongiolides, which have been studied more in recent years, have also played an important role in the discovery of new anti-tumor targets and the development of anti-cancer drugs with new mechanisms of action. , and become a tool for researching new antitumor drugs. [0003] The inventor's research has learned that Trichoderma auranthoderma ( Trichoderma citrinoviride. ) IBPT-4 (preser...
