Abstract
The invention discloses an application of Lycojaponicumin B in preparation of a medicine for treating gastric cancer, belonging to the technical field of new applications of medicines. According to the application disclosed by the invention, the Lycojaponicumin B is discovered to have the remarkable inhibitory effects on the growth of human gastric cancer cell strains including HGC-27, MGC-803, BGC-823 and SGC-7901 through the evaluation of in vitro MTT (methyl thiazolyl tetrazolium) antineoplastic activity. Therefore, the Lycojaponicumin B can be used for preparing the gastric cancer resisting medicine and has good development and application prospects. The application of the Lycojaponicumin B in preparation of the medicine for treating gastric cancer, disclosed by the invention, is disclosed for the first time. The skeleton type of the Lycojaponicumin B belongs to a brand new skeleton type, and the inhibitory activity of the Lycojaponicumin B on gastric cancer cells is unexpectedly strong.
Description
Technical field
The present invention relates to the new purposes of compound L ycojaponicumin B, relate in particular to the application of Lycojaponicumin B in the anti-gastric cancer medicine of preparation.
Technical background
Cancer is to one of disease of human life's health hazard maximum, and annual have a large amount of people to die from cancer.The research and development of cancer therapy drug are the focuses of study of pharmacy always.In antitumor drug, have 74% to be the natural product or derivatives thereof, as paclitaxel and derivant thereof are exactly the reasonable antitumor drug of effect clinically at present.Therefore, from natural product, searching anticancer compound or lead compound have great importance.
The compound L ycojaponicumin B the present invention relates to is one and within 2012, delivers (Wang, X. J. et al., 2012. Lycojaponicumins A-C, Three Alkaloids with an Unprecedented Skeleton from Lycopodium japonicum. Organic Letters 14 (10), 2614-2617.) New skeleton compound, this compound has brand-new framework types, belong to open first for the purposes in preparation treatment gastric cancer medicine the present invention relates to, because framework types belongs to brand-new framework types, and its inhibition for stomach cancer cell is active unexpectedly strong, there do not is the possibility that is provided any enlightenment by other compounds, possesses outstanding substantive distinguishing features, control for gastric cancer simultaneously obviously has significant progress.
Summary of the invention
The invention provides the application of compound L ycojaponicumin B in preparing antitumor drug.
The present invention adopts following technical scheme: the application of Lycojaponicumin B in the anti-gastric cancer medicine of preparation, and the structural formula of Lycojaponicumin B is as shown in formula I:
The present invention finds by external MTT anti-tumor activity evaluation, and Lycojaponicumin B also has significant inhibitory action to the growth of human stomach cancer cell line HGC-27, MGC-803, BGC-823 and SGC-7901, suppresses the IC of this 4 strain Growth of Cells
50value is respectively 2.13 ± 0.19 μ M, 1.41 ± 0.29 μ M, 3.49 ± 0.47 μ M and 1.38 ± 0.39 μ M.Therefore, Lycojaponicumin B can, for the preparation of anti-gastric cancer medicine, have good development prospect.
Purposes for the Lycojaponicumin B the present invention relates in preparation treatment gastric cancer medicine belongs to open first, because framework types belongs to brand-new framework types, and its inhibition for stomach cancer cell is active unexpectedly strong, there do not is the possibility that is provided any enlightenment by other compounds, possess outstanding substantive distinguishing features, the control for gastric cancer simultaneously obviously has significant progress.
The present invention is further detailed explanation by the following examples, but protection scope of the present invention is not subject to any restriction of specific embodiment, but be limited by claim.
The specific embodiment
The preparation method of compound L ycojaponicumin B involved in the present invention is referring to document (Wang, X. J. et al., 2012. Lycojaponicumins A-C, Three Alkaloids with an Unprecedented Skeleton from Lycopodium japonicum. Organic Letters 14 (10), 2614-2617.).
The present invention is further detailed explanation by the following examples, but protection scope of the present invention is not subject to any restriction of specific embodiment, but be limited by claim.
Embodiment 1: the preparation of compound L ycojaponicumin B tablet involved in the present invention:
Get 20 and digest compound Lycojaponicumin B, add conventional adjuvant 180 grams that prepare tablet, mix, conventional tablet machine is made 1000.
Embodiment 2: the preparation of compound L ycojaponicumin B capsule involved in the present invention:
Get 20 and digest compound Lycojaponicumin B, add the conventional adjuvant for preparing capsule as starch 180 grams, mix, encapsulatedly make 1000.
Further illustrate its pharmaceutically active below by pharmacodynamic experiment.
Experimental example: adopt the growth inhibited effect of mtt assay assessing compound Lycojaponicumin B to human stomach cancer cell line
1. method: in the cell of growth logarithmic (log) phase: human stomach cancer cell line HGC-27, MGC-803, BGC-823 and SGC-7901(buy from Chinese Academy of Sciences's cell bank) with 1.5 * 10
4the concentration kind is in 96 orifice plates.Suck original culture medium after cell culture 24 h are adherent.Test is divided into blank group, drug treating group.Blank group is changed 1640 culture medium containing 10% hyclone; It is 100 μ M that the drug treating group is changed containing concentration, 50 μ M, 10 μ M, 1 μ M, 0.1 μ M, the culture medium of the Lycojaponicumin B of 0.01 μ M and 0.001 μ M.After cultivating 48 h, add the MTT of concentration 5mg/mL, continue to be put in CO
2incubator is cultivated 4 h, then suck 100 μ L supernatants along culture fluid top, add 100 μ L DMSO, 10 min are placed in dark place, utilize microplate reader (Sunrise company product) to measure light absorption value (wavelength 570 nm), and calculating the cell survival situation according to light absorption value, 6 repeating holes are established in each processing.Cell survival rate (%)=Δ OD
drug treating/ Δ OD
blank* 100.
2. result: Lycojaponicumin B has significant inhibitory action to the growth of human stomach cancer cell line HGC-27, MGC-803, BGC-823 and SGC-7901.This compound suppresses the IC of human stomach cancer cell line HGC-27, MGC-803, BGC-823 and SGC-7901 growth
50value is respectively: 2.13 ± 0.19 μ M, 1.41 ± 0.29 μ M, 3.49 ± 0.47 μ M and 1.38 ± 0.39 μ M.
By above-described embodiment, shown, Lycojaponicumin B of the present invention has good inhibitory action to the growth of human stomach cancer cell line HGC-27, MGC-803, BGC-823 and SGC-7901.Prove thus, Lycojaponicumin B of the present invention has anti-gastric cancer activity, can be for the preparation of anti-gastric cancer medicine.
