Abstract

The present invention relates to a kind of penemol E1 derived from Trichoderma aurantiacus and its application in gastric cancer. The structural characteristics of this compound are: it contains a pentacyclic amide molecular skeleton, a carbonyl group connected to a ten-carbon saturated fat long chain, a methyl group connected to N, and two hydroxyl groups in the molecule. Experiments have confirmed that the alkaloid compounds have good inhibitory activity against gastric cancer cells. It can be used to prepare gastric cancer cell proliferation inhibitory drugs or anti-gastric cancer drugs for anti-tumor research.

Description

technical field [0001] The invention relates to a kind of penemenol E1 derived from Trichoderma aurantii and its application in gastric cancer. 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...
