Abstract
The invention discloses application of Houttuynoid C in preparing a medicament for treating pancreatic cancer, and belongs to the technical field of new use of medicaments. Houttuynoid C is found to have an obvious inbibitional effect on the growth of human pancreatic cancer cell lines PANC-1 and BXPC-3 through MTT (Methyl Thiazolyl Ternzolinm) anticancer activity evaluation in vitro. Therefore, Houttuynoid C can be used for preparing the anti-pancreatic cancer medicament and has excellent prospects in development and application. The use of Houttuynoid C in preparing the medicament for treating the pancreatic cancer involved in the invention is disclosed for the first time; the framework type of Houttuynoid C is a brand new framework type; and Houttuynoid C has an unexpectedly high inhibition activity for the pancreatic cancer cells.
Description
Technical field
The present invention relates to the new purposes of compound H outtuynoid C, relate in particular to the application of Houttuynoid C in the anti-cancer of pancreas medicine of preparation.
Technical background
Cancer is one of disease to human life's health hazard maximum, has a large amount of people to die from cancer every year.The research and development of cancer therapy drug are the focuses of study of pharmacy always.In antitumor drug, have 74% to be natural product or derivatives thereof, if paclitaxel and derivant thereof are exactly the reasonable antitumor drug of effect clinically at present.Therefore, from natural product, find anticancer compound or lead compound has great importance.
The compound H outtuynoid C the present invention relates to is one and within 2012, delivers (Chen, S. D. et al., 2012. Houttuynoid C_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletons from Houttuynia cordata. Organic Letters 14 (7), 1772 – 1775.) New skeleton compound, this compound has brand-new framework types, current purposes only relates to anti-herpes simplex virus activity (Chen, S. D. et al., 2012. Houttuynoid C_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletons from Houttuynia cordata. Organic Letters 14 (7), 1772 – 1775.), purposes for the Houttuynoid C the present invention relates in preparation treatment cancer of pancreas medicine belongs to open first, because framework types belongs to brand-new framework types, and its inhibition for pancreatic cancer cell is active unexpectedly strong, there is not the possibility that is provided any enlightenment by other compounds, possesses outstanding substantive distinguishing features, for the control of cancer of pancreas, obviously there is significant progress simultaneously.
Summary of the invention
The invention provides compound H outtuynoid C in the application of preparing in antitumor drug.
The present invention adopts following technical scheme: the application of Houttuynoid C in the anti-cancer of pancreas medicine of preparation, and the structural formula of Houttuynoid C is as shown in formula I:
Formula I
The present invention finds by external MTT anti-tumor activity evaluation, and Houttuynoid C also has significant inhibitory action to the growth of human pancreas cancer cell strain PANC-1 and BXPC-3, suppresses the IC of this 2 strain Growth of Cells
50value is respectively 1.01 ± 0.13 μ M and 1.12 ± 0.24 μ M.Therefore, Houttuynoid C can, for the preparation of anti-cancer of pancreas medicine, have good development prospect.
Purposes for the Houttuynoid C the present invention relates in preparation treatment cancer of pancreas medicine belongs to open first, because framework types belongs to brand-new framework types, and its inhibition for pancreatic cancer cell is active unexpectedly strong, there is not the possibility that is provided any enlightenment by other compounds, possess outstanding substantive distinguishing features, for the control of cancer of pancreas, obviously there is significant progress simultaneously.
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 H outtuynoid C involved in the present invention is referring to document (Chen, S. D. et al., 2012. Houttuynoid C_E, Anti-Herpes Simplex Virus Active Flavonoids with Novel Skeletons from Houttuynia cordata. Organic Letters 14 (7), 1772 – 1775.).
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 H outtuynoid C tablet involved in the present invention:
Get 20 and digest compound Houttuynoid C, add 180 grams of conventional adjuvants preparing tablet, mix, conventional tablet machine is made 1000.
Embodiment 2: the preparation of compound H outtuynoid C capsule involved in the present invention:
Get 20 and digest compound Houttuynoid C, add the conventional adjuvant of preparing capsule as 180 grams of starch, 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 Houttuynoid C to human pancreas cancer cell strain
1. method: in growth logarithmic (log) phase cell: human pancreas cancer cell strain PANC-1 and BXPC-3(buy from Chinese Academy of Sciences's cell bank) with 1.5 × 10
4concentration kind is in 96 orifice plates.After cell culture 24 h are adherent, suck original culture medium.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 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 Houttuynoid C of 0.01 μ M and 0.001 μ M.Cultivate after 48 h, add the MTT of concentration 5 mg/mL, continue to be put in CO
2incubator is cultivated 4 h, then along culture fluid top, suck 100 μ L supernatants, add 100 μ L DMSO, 10 min are placed in dark place, utilize microplate reader (Sunrise company product) to measure light absorption value (wavelength 570nm), and calculating 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: Houttuynoid C has significant inhibitory action to the growth of human pancreas cancer cell strain PANC-1 and BXPC-3.This compound suppresses the IC of human pancreas cancer cell strain PANC-1 and BXPC-3 growth
50value is respectively 1.01 ± 0.13 μ M and 1.12 ± 0.24 μ M.
By above-described embodiment, shown, Houttuynoid C of the present invention has good inhibitory action to the growth of human pancreas cancer cell strain PANC-1 and BXPC-3.Prove thus, Houttuynoid C of the present invention has anti-cancer of pancreas activity, can be for the preparation of anti-cancer of pancreas medicine.
