Abstract

The invention relates to penem enol E1 derived from trichoderma citrinoviride and application in preparation of an anti-oral epidermoid carcinoma drug. The compound is structurally characterized by containing a molecular skeleton of pentacyclic amide, a carbonyl connected with a long n-decyl saturated aliphatic chain, a methyl connected to N and molecules existing in two hydroxyl groups. An experiment proves that the alkaloid compound has good oral epidermoid carcinoma inhibiting activity. The penem enol E1 can serve as a drug for inhibiting oral epidermoid carcinoma cell proliferation or the anti-oral epidermoid carcinoma drug for antitumor research.

Description

technical field [0001] The invention belongs to the field of medicinal chemistry, and in particular relates to penemenol E1 derived from Trichoderma auranthoderma and its application in the preparation of anti-oral epidermal cancer drugs. 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 s...
