Description
Technical field
The present invention relates to a class 8-oxygen-8H-acenaphthene also the amino of [1,2-b] pyrroles-9-nitrile or halogen substituted derivative and in vivo, external cell death inducing effect and as the application of anticancer compound.
Background technology
Along with the research that pair cell death process and mechanism deepen continuously, apoptosis becomes the new target spot of antitumor drug research.Because the characteristic of tumour cell is to resist apoptosis by escaping the organism signals-modulating, reach " immortality ".So effectively inducer of apoptosis will fundamentally suppress the existence of tumour cell and the continuation abnormal shapeization of precancerous lesion.No matter as the instrument of oncology fundamental research or the medicine of clinical treatment tumour, inducer of apoptosis all has great value.At present, comprise Calbiochem (German), Merck (German), Promage how tame biotech firms such as (USA) has all developed and has continued exploitation apoptosis induction product.There are some inducer of apoptosis to become the clinical chemotherapeutics of using, for example camptothecine (Y Pommier.Diversity ofDNA topoisomerases I and inhibitors.Biochimie, 1998,80; 255-270.).These products all belong to vitamin A, non-steroidal anti-inflammatory drugs, polyphenol, vanilla element and topoisomerase enzyme inhibitor, as seen they are still based on the chemosynthesis product of natural drug or its analogue, all exist the source not enough, cost an arm and a leg, problem such as selectivity is low, side reaction is big, effect is undesirable.In order to find new chemotherapeutics, The National Cancer Institute random screening anti-tumor activity (the John N.Weinstein of 300000 different sorts compounds, Timothy GMyers, Patrick M.O ' Connor, et al.Aninformation-intensive approach to the molecular pharmacology of cancer.Science, 1997,275; 3430-349.).In recent years, Qian Xuhong etc. also synthesizes, detects, has reported multiple anticancer compound.The target of this research field be find new texture, lower median lethal concentration, be to act on the compound that all has anti-tumor activity by way of, vivo and vitro with apoptosis-induced.
Summary of the invention
The present invention is successfully preparing new fluorescent chromophore 8-oxygen-8H-acenaphthene also [1,2-b] pyrroles-9-nitrile and derivative (ZL021484007 thereof, Qian Xuhong, on basis Xiao Yi), at parent 8-oxygen-8H-acenaphthene also [1,2-b] introduce new active group on pyrroles-9-nitrile, formulated novel cell inducer of apoptosis and antineoplastic compound involved in the present invention.

As in the body, the application of cell in vitro inducer of apoptosis and antineoplastic compound.Method is: at first measure IC by mtt assay
50Selecting the HELA cell is target cell, becomes density to be about 5 * 10 cell dilution with the RPMI1640 nutrient solution
5The cell suspension of individual/ml adds in the 96 porocyte culture plates, and every hole adds 200 μ l tumour cell suspensions.The 100%DMSO solution that adds compd A, B respectively, final concentration 100,50,10,5,0.5,0.1,0.05,0.01 μ M establishes cell control group and positive drug cyclophosphamide-a control group simultaneously.CO
2Every hole adds MTT solution 20 μ l after hatching 24hrs in the incubator, measures optical density(OD) (OD) value under the 570nm with microplate reader, according to optical density value, calculates the survival rate of each hole tumour cell.
The result shows the IC of the compound B-11 that cytotoxicity is the strongest
50=0.17 μ M (0.56 μ g).Other Compound I C
50Value is between 0.4-6.8 μ M.
The active experimental technique of anti-tumor in vivo is: at first cultivate hepatoma cell line H22, it is subcutaneous only to be inoculated in the right armpit of mouse by 200 μ l/, is prepared into animal model for tumour.In back 5 days of inoculation, the knurl piece formed.Beginning is according to the concentration gradient 30%DMSO solution of vein or local injection compd A, B once a day.Experimental session is measured tumour major diameter (a) and perpendicular minor axis (b), by formula 1/2ab twice weekly
2It is long-pending to calculate the knurl block.Observe the animals survived time.The result shows that A series compound and B series compound all have and suppresses tumor growth in various degree, prolongs the effect of tumor model survival time of animals.
The present invention also by flow cytometer detected A, B series compound in vivo, external evoked apoptosis and the effect of retardance cell cycle.Method is in the in vitro tests, and selecting the HeLa cell is target cell, becomes density to be about 5 * 10 cell dilution with the RPMI1640 nutrient solution
5The cell suspension of individual/ml adds in the 96 porocyte culture plates, and every hole adds 200 μ l tumour cell suspensions.Add compd A, B respectively by concentration gradient, establish cell control group and positive drug cyclophosphamide-a control group simultaneously.CO
2After hatching 24 hours in the incubator, 70% cold ethanol is fixed; In the in vivo test, the tumor tissues of the tumor model animal of the compound treatment of learning from else's experience, the preparation single cell suspension is set undressed tumor model animal groups simultaneously and is contrast.70% cold ethanol is fixed.Flush away stationary liquid before the last machine testing, propidium iodide dyeing, flow cytometer detects.Computer automatically to the position at each peak, peak heights, cell cycle each the time phase per-cent analyze.The result shows that with dose-dependent mode cell death inducing, apoptosis rate is at 9%-31% between 0.01-10 μ M for the compound B-11 of best results.Cell-cycle arrest is in the S phase.Other compound all relies on mode inducing culture apoptosis with dosage.
A, B series compound be all as antineoplastic compound or cell death inducer, with the mode of cell death inducing in vivo, the vitro inhibition growth of tumor.
