Abstract
The invention discloses dehydroabietylamine derivatives, which have a structural formula as follow: The dehydroabietylamine derivatives can be used to prepare antitumor drugs.
Description
The application is " dehydroabietylamine derivatives and the application in bactericidal and antineoplastic medicaments thereof " (applying date: on June 18th, 2009; Application number: dividing an application 200910033318.9).
One, technical field
The present invention relates to dehydroabietylamine derivatives Schiff bases compound, and the application in the preparation antitumor drug.
Two, background technology
Extraction or the synthetic different positions on resinous acid C ring and B ring contains the novel compound of different substituents from natural phant; Studying their biological activity can find; Many products have some antibiotic, anticancer, the anti-AIDS that is different from parent compound and other antiviral biological activitys, and this respect has become a research focus at present.From Sequoia sempervirens, separate having obtained the C ring and contain the product that hydroxyl, B ring contain the dehydrogenation fir alkane skeleton of carbonyl, these products have good antitumour activity to lung cancer and mammary cancer; The dehydroabietic acid verivate that contains adjacent diphenol on the C ring is very effective organism free-radical scavengers, has the value of developing new drug; The dehydroabietic acid verivate that two hydroxyls are arranged on C encircles last 11 and 12, finding has good active to fungi and cancer cells.Dehydroabietylamine is the typical composition of rosin Amine D, has optical activity, is a kind of important Forest products, has a wide range of applications at aspects such as papermaking, medicine, agricultural chemicals, chemical industry.Because it is the verivate of sylvic acid, thereby dehydroabietylamine and acetate thereof has certain biological activity, can be used as the anti-algae agent of excellent sterilant, sterilant and mildew-resistant; In addition, owing to have natural chiral carbon in the dehydroabietylamine, thereby it can be used as good optical resolution agent.Dehydroabietylamine also is used as metal inhibitor, crude oil demulsifier, oil dope, tensio-active agent etc.
Three, summary of the invention
Technical problem: the present invention provides one type of dehydroabietylamine derivatives Schiff bases compound, and the application in the preparation antitumor drug.
Technical scheme: dehydroabietylamine derivatives is characterized in that its structural formula representes:
The application of above-mentioned dehydroabietylamine derivatives in the preparation antitumor drug.
Beneficial effect: dehydroabietylamine derivatives Schiff bases compound has extraordinary toxic action to leukemia cell (U-937 and HL-60), ovarian cancer cell (Hey-1B), prostate cancer cell (Pc-3 and Du-145) and small white mouse dermal melanin glucagonoma (B16).

Embodiment 2
Formula 9 described novel dehydroabietylamine derivatives Schiff alkali have been done external antitumour activity measured, ovarian cancer cell (Hey-1B) is as the cancer cells that is screened.Concrete experimental technique is following:
Ovarian cancer cell strain Hey-1B cultivates in the DMEM Zooblast culture medium, has added 10% reinforced bovine serum albumin and microbiotic in the substratum, feeds damp atmosphere, controlled temperature 37 ℃, CO
2Content 5%.Non-radioactive cell proliferation detects the cytoactive of confirming Hey-1B with colourimetry (MTT).
Measuring method with reference to manufacturers (Promega, Madison, operation instructions WI), concise and to the point step is following: in each hole of 96 orifice plates, plant 1 * 10
4Individual cell is cultivated and is used sample preparation after one day, and the concentration of treatment gradient is respectively 2.5,5, and 10,20,40,80 μ g/mL cultivated 48 hours.After cultivating end, (be diluted to 40% with 1 * PBS, v/v), 37 ℃ are continued to cultivate 2 hours, use 96 orifice plates to read the plate device at last and detect light absorption ratio OD at the 490nm place in each hole, to add 50 μ L Cell Titer 96Aqueous reagent
490(full wavelength scanner declines and coils analyser Spectra Max 340).The average OD value in each hole of gained is calculated its inhibition rate of tumor cell according to control samples by statistical test.
Experimental result: sample dissolution is in the DMEM Zooblast culture medium, and the cancer cells of growth obviously is suppressed, the Hey-1B apoptosis.
