Embodiment 1

[0015] Example 1 Fermentative production and separation and purification of compounds

[0016] 1. Fermentation production

[0017] Fermentation culture of production bacteria: according to the conventional method of cultivating microorganisms, take Trichoderma auranthoderma ( Trichoderma citrinoviride. ) IBPT-4 (preserved in the China Center for Type Culture Collection on January 25, 2013, address: Wuhan University, Wuhan, deposit number: CCTCC NO: M 2013055) appropriate amount, inoculated on PDA solid slant medium, in Cultivate for 4 days in a 28°C incubator.

[0018] Get the Trichoderma auranthoderma ( Trichoderma citrinoviride. ) appropriate amount of IBPT-4, inoculated into 400mL culture medium [composition of culture medium (g / L): mannitol 20.0, yeast extract 3.0, maltose 20.0, monosodium glutamate 10.0, glucose 10.0, KH 2 PO 4 0.5, MgSO 4 0.3, NaCl 6.0 constant volume] in a 1000mL Erlenmeyer flask, after 30 days of static culture at 28°C, mycelia and fermentati...

Embodiment 2

[0026] Example 2 Test of anti-tumor activity in vitro

[0027] 1. Experimental samples and experimental methods

[0028] Preparation of the test sample solution: the test sample is the pure product of the compound isolated and refined in Example 1. Accurately weigh an appropriate amount of sample, and prepare a solution with the required concentration with methanol for activity measurement.

[0029] The subculture of cell lines and cells adopts lung cancer cell lines, and the cells use RPMI-1640 medium containing 10% FBS at 37°C and 5% CO 2 Subculture in an incubator.

[0030] Cell Proliferation Inhibitory Activity Test Method

[0031] Tetrazolium salt (MTT) method: Take cells in the logarithmic growth phase and adjust the cell density to 2×10 per ml 5 Cells were inoculated in 96-well cell culture plates at 200 microliters per well, and kept at 37°C in 5% CO 2 incubator for 4 hours. Add 2 microliters of sample solution or blank solution to each well, and after 24 hours o...

Abstract

The invention discloses an application of penilloenol E1 derived from Trichoderma citrinoviride in lung cancer. The structure of the compound is characterized in that the structure contains a pentacycloamide molecule skeleton, and a carbonyl group connected C10 saturated fat long chain, N is connected with a methyl group, and two hydroxyl groups exist in the molecule. Experiments confirm that the above alkaloid compound has good inhibition activity to lung cancer cells, can be used for preparing lung cancer cell proliferation inhibition medicines or anti-lung cancer medicines, and is used for antitumor researches.

Description

technical field [0001] The invention relates to the application of an alkaloid compound penemenol E1 derived from Trichoderma aurantii in lung 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 ...
