Abstract
The invention discloses application of Chukrasone B in preparation of a medicine for treating gastric cancer, and belongs to the technical field of new application of medicines. The in-vitro MTT (3-4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) antitumor activity evaluation shows that Chukrasone B has remarkable inhibition effect on the growth of human gastric cancer cell lines HGC-27, MGC-803, BGC-823 and SGC-7901, so that Chukrasone B has a good development and application prospect and can be applied to the preparation of the medicine for treating gastric cancer. The application of Chukrasone B in the preparation of the medicine for treating gastric cancer is disclosed for the first time; the framework type of Chukrasone B is brand new; Chukrasone B brings unexpected inhibition activity for gastric cancer cells.
Description
Technical field
The present invention relates to the new purposes of Compound C hukrasone B, relate in particular to the application of Chukrasone 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, having 74% to be the natural product or derivatives thereof, is exactly the reasonable antitumor drug of effect clinically at present as paclitaxel and derivant thereof.Therefore, from searching anticancer compound or lead compound natural product, have great importance.
The Compound C hukrasone B the present invention relates to is one and delivered (Liu in 2012, H.B.et al., 2012.Chukrasones A and B:Potential Kv1.2Potassium Channel Blockers with New Skeletons from Chukrasia tabularis.Organic Letters14 (17), 4438 – 4441.) New skeleton compound, this compound has brand-new framework types, current purposes only relates to potassium-channel and suppresses active, for the purposes in preparation treatment gastric cancer medicine the present invention relates to, belong 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, 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 C hukrasone B in preparing antitumor drug.
The present invention adopts following technical scheme: the application of Chukrasone B in the anti-gastric cancer medicine of preparation, and the structural formula of Chukrasone B is as shown in formula I:
The present invention finds by external MTT anti-tumor activity evaluation, and Chukrasone 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 6.11 ± 0.79 μ M, 5.12 ± 0.18 μ M, 7.12 ± 0.68 μ M and 7.59 ± 0.93 μ M.Therefore, Chukrasone B can, for the preparation of anti-gastric cancer medicine, have good development prospect.
For the purposes of the Chukrasone B the present invention relates in preparation treatment gastric cancer medicine, belong 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 subjected to any restriction of specific embodiment, but be limited by claim.
The specific embodiment
The preparation method of Compound C hukrasone B involved in the present invention is referring to document (Liu, H.B.et al., 2012.Chukrasones A and B:Potential Kv1.2Potassium Channel Blockers with New Skeletons from Chukrasia tabularis.Organic Letters14 (17), 4438 – 4441.).
The present invention is further detailed explanation by the following examples, but protection scope of the present invention is not subjected to any restriction of specific embodiment, but be limited by claim.
Embodiment 1: the preparation of Compound C hukrasone B tablet involved in the present invention:
Get 20 and digest compound Chukrasone B, add conventional adjuvant 180 grams that prepare tablet, mix, conventional tablet machine is made 1000.
Embodiment 2: the preparation of Compound C hukrasone B capsule involved in the present invention:
Get 20 and digest compound Chukrasone B, add the conventional adjuvant such as starch 180 grams that prepare capsule, mix, encapsulatedly make 1000.
Below by pharmacodynamic experiment, further illustrate its pharmaceutically active.
Experimental example: adopt the growth inhibited effect of mtt assay assessing compound Chukrasone B to human stomach cancer cell line
1. method: the cell that is in the 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.After cell culture 24h is adherent, suck original culture medium.Test is divided into blank group, drug treating group.Blank group is changed 1640 culture medium that contain 10% hyclone; It is 100 μ M that the replacing of drug treating group contains concentration, 50 μ M, 10 μ M, 1 μ M, 0.1 μ M, the culture medium of the Chukrasone B of 0.01 μ M and 0.001 μ M.After cultivating 48h, add the MTT of concentration 5mg/mL, continue to be put in CO
2Incubator is cultivated 4h, then along culture fluid top, suck 100 μ L supernatants, add 100 μ L DMSO, 10min is placed in dark place, utilize microplate reader (Sunrise company product) to measure light absorption value (wavelength 570nm), 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: Chukrasone 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: 6.11 ± 0.79 μ M, 5.12 ± 0.18 μ M, 7.12 ± 0.68 μ M and 7.59 ± 0.93 μ M.
By above-described embodiment, shown, Chukrasone 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, Chukrasone B of the present invention has anti-gastric cancer activity, can be for the preparation of anti-gastric cancer medicine.
