Example Embodiment

[0023] Example 1

[0024] Prepare solid PDA medium (15 L per liter of water is divided into 750 90 mm glass petri dishes, each with about 20 mL of medium, sterilized and connected to activated wild abalone mushroom ( Pleurotus cystidiosus ) ZYB2013 (preserved in the China Type Culture Collection on June 15, 2014, the preservation number is CCTCC M 2014256) mycelial block, cultured in a 28 ℃ constant temperature incubator for 43 days. After cultivation, the wild abalone mushroom mycelium and the culture medium were chopped up, placed in a tap bottle, and an organic solvent (ethyl acetate: methanol: acetic acid volume ratio = 80:15:5) was added for extraction 6 times, and the extract was collected , Concentrated under reduced pressure at 40 ℃ to a paste, the paste was extracted with pure water and ethyl acetate 1:1 6 times, the ethyl acetate phase was dehydrated with anhydrous sodium sulfate, concentrated under reduced pressure at 40 ℃ to a paste, A crude ethyl acetate extract (4....

[0038] Example 2

[0039] The inhibitory effects of the compounds on prostate cancer cells DU-145, C42B and LNCaP were measured by MTT method. Make the cultured prostate cancer cells DU-145, C42B and LNCaP into a single cell suspension, count and dilute to a cell concentration of 6×10 with a cell plate 4 Pieces / mL. Seed cells in a 96-well plate, 80μL per well. There are also 2 wells with no cells and only 80 μL culture medium [Dulbecco’s modified Eagle’s media (DMEM, Gibco, USA) + 10% calf serum] blank control wells for instrument zero adjustment. Set at 37℃, 5% CO 2 Incubate in the incubator for 24 h, and then add 20 μL of the sample diluted with the culture fluid. At the same time, add 20 μL of cisplatin to the positive control wells, and add 20 μL of culture medium to the negative control wells and blank control wells. Continue to incubate for 72 hours and add 10 μL of 5 mg / mL MTT to each well. React at 37°C for 3 hours, add 100 μL 10% SDS-0.01mol / L HCl to each well to dis...

Abstract

The invention relates to sesquiterpene compounds and an application thereof, belonging to the field of biological medicines. The sesquiterpene compounds have the structural formula as the specification. The compounds are obtained from (Pleurotus cystidiosus) ZYB2013, and the sesquiterpene compounds are used as antitumor drugs or tumor cell proliferation inhibiting drugs. The sesquiterpene compounds provided by the invention are novel in structure and strong in antitumor activity. The sesquiterpene compounds are found to have a relatively strong inhibiting effect for prostate cancer cells DU-145, C42B and LNCaP through measuring the antitumor activities of the compounds. A result shows that the sesquiterpene compounds have antitumor activity so as to be applied to preparation of antitumor drugs or other biological activity primers.

Description

technical field [0001] The invention relates to a sesquiterpene compound and its application, belonging to the field of biomedicine. Background technique [0002] Sesquiterpenes are natural terpenoids with 15 carbon atoms in the molecule. Sesquiterpenoids are widely distributed and are most abundant in magnoliales, rutales, cornales and asterales. In plants, it often exists in volatile oils in the form of alcohols, ketones, lactones, etc., and is the main component of high boiling point parts in volatile oils. Most of them have strong aroma and biological activity, and are important raw materials for medicine, food and cosmetic industries. [0003] The inventor has studied and learned that wild abalone mushroom ( Pleurotus cystidiosus ) ZYB2013 (preserved in the China Center for Type Culture Collection on June 15, 2014, with the preservation number CCTCC M 2014256), the hyphae in the early stage of solid culture are white, and the mycelium will produce black secretions in...
