Background technology
Malignant tumour is one of principal disease of serious threat human life and quality of life.According to 2007 data that the end of the year, the Ministry of Health announced, malignant tumour has become first cause of the death of China urban and rural residents.In recent years, chemotherapy of tumors has been obtained sizable progress, the tumour patient survival time obviously prolongs, particularly the treatment to leukemia, malignant lymphoma etc. has had than quantum jump, but treatment the most serious, that account for the solid tumor (comprise lung cancer, liver cancer, bladder cancer and colorectal carcinoma etc.) of malignant tumour more than 90% still fails to reach promising result to the harm humans life and health.
Along with the progress at full speed of life science, tumour mechanism is progressively illustrated, and has occurred the inhibition tumor growth factor in succession, intervenes the tumor signal conduction, has suppressed new direction such as tumor-blood-vessel growth and inducing apoptosis of tumour cell; But because the pathogenesis of malignant tumour is very complicated, clinical practice in recent years shows that they have only with the cell toxicity medicament combined utilization and just can obtain clinical efficacy preferably.Therefore, as the drug screening target, find that selectively acting is significant in the new type anticancer medicine of efficient, the low toxicity of specific target spot, high specificity with key enzyme relevant in the tumour cell with differentiation and proliferation.
Topoisomerase I (Top1) has become one of crucial target enzyme of design new type anticancer medicine in recent years.It is the indispensable enzyme of cells survival, the whole process of participate in dna replication dna, transcribing, recombinate, repairing; And in the kinds of tumor cells especially the content of Top1 such as lung cancer, cancer of the stomach, colorectal carcinoma, ovarian cancer apparently higher than normal cell.These all make Top1 inhibitor class medicine, and not only curative effect height, antitumor spectra are wide, and tumour cell is also had good selectivity, are now classified as one of six big series antineoplastic medicaments of primary study by the American National ICR.
In all kinds of Top1 inhibitor, the research of camptothecine (CPT) analog derivative is the most deep, also is the most classical specific inhibitor of Top1.In this compounds, Yi Nuo successfully goes on the market for health (CPT-11) and topotecan, is used to the treatment of metastatic colorectal cancer and obstinate ovarian cancer etc., has obtained good curative effect.Yet also there is following outstanding problem in this compounds: 1) internal metabolism instability, and active essential E cyclic lactone structure is hydrolyzed into carboxylate form too quickly in human body, and carboxylate form is not only invalid to Top1, and easilier combines with human serum albumin; 2) Top1 cutting mixture (Top1cc) time that need keep a fixed length just can be converted into dna damage, however camptothecine be easy to dissociate from Top1cc, must prolong quiet time when therefore using camptothecine clinically; 3) poorly water-soluble, the five rings conjugate planes structure of camptothecine uniqueness has stronger hydrophobicity, causes it water-soluble relatively poor; 4) there is certain toxic side effect in camptothecine, such as reduce from cell, feel sick, vomiting etc., limited safe dose and and then limited curative effect of medication; 5) resistance, the camptothecine tolerance mutant strain report of existing now several Top1, modal have an Asn722, and the sudden change of Arg364 etc. all can cause the chemical sproof generation of camptothecine.
Non-camptothecin Top1 inhibitor has become the focus of anticarcinogen research in recent years.The Indolocarbazole compounds is to study a comparatively deep class at present, J-107088 in this compounds (Edotecarin) has entered clinical study, yet there are some researches show that this compounds is not the specific inhibitor of Top1, also have the activity of arrestin kinase c or check point kinase c hk-1.In addition, LuotonineA, LamellarinD separate the Top1 inhibitor that obtains from nature in recent years, but mostly there are problems such as complex structure, poor specificity, toxic side effect are bigger in they, at present clinical widely use still have only camptothecin antineoplastic agents.
In order to find the Top1 inhibitor of brand new type, we have carried out the virtual high flux screening research of Top1 inhibitor in earlier stage, have found that successfully several quasi-medicated properties are good, the lead compound of no potential carinogenicity.Investigate based on activity, novelty and binding molecule graphics, our finally selected purchase obtains part of compounds and presses down enzyme and cytotoxic activity test, the result shows: we find that first 1-azepine xanthone-3-Carbox amide has the activity of very strong inhibition Top1, significantly be better than the marketed drug topotecan, the cytotoxic activity test result shows that logarithm kind tumour cell has shown certain anti-tumor activity.Molecular Docking Study shows that such lead compound can form two hydrogen bond actions with the crucial avtive spot residue A rg364 that we discern the Topo I target enzyme of discovery in earlier stage, amide group on the side chain can form optionally effect with the cytosine(Cyt) in DNA cleavage site downstream on the target enzyme+1, this makes this compounds compare with existing Top1 inhibitor to have greater advantages, is expected to overcome well the resistance problem of existing antitumor drug.
Need explanation, though this compounds compound can have been bought and obtains individually, the document the inside do not announce physico-chemical property, the preparation method of this compounds, and more this compounds can not be used for antineoplastic report.Therefore, our 1-azepine xanthone-3-Carbox amide of finding has first been represented the active compound for anti tumor of a class brand new.

Embodiment 5: the cytotoxicity of compound of the present invention
(1) experiment material and method:
1. experiment material
(1) experimental strain
This experiment has adopted 3 kinds of human cancer cell strains as the screening object, and this JEG-3 provides by Shanghai Institute of Pharmaceutical Industry's Pharmacology Lab.
1) human lung cancer cell A549
2) human colon cancer cell Colo205
3) human breast cancer cell MDA-MB-435
(2) nutrient solution is that RPMI1640+15%NBS+ is two anti-.Used full-automatic microplate reader model is: WellscanMK-2, production firm: Labsystems.Import 96 well culture plates etc.
2. experimental technique
The extracorporeal anti-tumor tumor activity adopts mtt assay.
Sample preparation: after DMSO (Merck) dissolving, add solution or uniform suspension that PBS (-) is made into 1000 μ g/ml, then with PBS (-) dilution that contains DMSO.
Nutrient solution: RPMI640+15%NBS+ is two anti-
Positive control medicine: hydroxycamptothecine
Experimental procedure is as follows:
Every hole adding concentration is 4~5 * 10 in 96 well culture plates
4The cell suspension 1000 μ l of individual/ml put 37 ℃, 5%CO
2In the incubator.Behind the 24h, add sample liquid, two multiple holes are established in 10 μ l/ holes, and 37 ℃, 5%CO
2Effect 72h.Every hole adds the MTT solution 20 μ l of 5m g/ml, adds lysate behind the effect 4h, and put in the incubator in 100 μ l/ holes, and the 570nmOD value is surveyed with the full-automatic microplate reader of MK-2 in the dissolving back.
(2) experimental result
Table 2.29 compound is to the in-vitro multiplication restraining effect of human body tumour cell
Example 6: topoisomerase I suppresses activity test
Utilization literature method (Kingsbury WD, Boehm JC, Jakas DR, et al.J Med Chem, 1991,34,98-107), part of compounds has been carried out topoisomerase I suppressed activity test, found that they have the activity of good inhibition Top1 in the 0.01-100uM scope.
To sum up, The compounds of this invention has certain antitumor action, it is worthy of note especially, this compounds has shown good selective toxicity to metastatic breast cancer cell, the antitumor drug of, low toxicity efficient for being developed as, high specificity is laid a good foundation, and has good exploitation and is worth.1-azepine xanthone of the present invention-3-Carbox amide is being represented the compound with anti-tumor activity of a class brand new, and this is for furtheing investigate and developing new antitumor drug and opened up new approach and direction.
