Abstract

The invention relates to an alkaloid compound from Trichoderma citrinoviride and an application thereof. The structure of the compound is characterized in that the compound contains a molecular skeleton of pentacyclic amide and contains an unsaturated ketone connecting a 8-carbon saturated aliphatic long-chain; a methyl group is connected at N; and there are two hydroxyl groups in the molecule. It is confirmed through experiments that the alkaloid compound has good antineoplastic activity and can be used to prepare a cell proliferation inhibitor or antineoplastic drug for antineoplastic researches.

Description

technical field [0001] The invention relates to an alkaloid compound derived from Trichoderma auranthoderma and application thereof. Background technique [0002] Alkaloids are a type of nitrogen-containing organic compounds produced by biological secondary metabolism. There are many types of alkaloids in nature, most of which come from plants, so they are also called plant alkaloids. Alkaloids have important physiological effects on humans and animals, including anti-asthma and antitussive, hypoglycemic, hypolipidemic, antibacterial, antitumor, analgesic, etc., among which antibacterial and antitumor activities are the most prominent. Natural structural alkaloids are an important source for discovering lead compounds in the research of innovative drugs, and there are nearly a hundred kinds of alkaloid drugs currently used in clinical practice. Studies have found that some marine fungi can produce alkaloids with novel structures and good activities in the process of seconda...
