Description
Invention field
The present invention relates to a kind of novel hydroxamic acid derivs with benzothiophene or thiophene skeleton.Described hydroxamic acid compound can be used for treating cancer.But described hydroxamic acid compound is inhibition of histone deacetylase and be applicable to the eventually end differentiation of selective induction tumor sexual cell, cell growth retardation and/or apoptosis also, thereby suppresses this class cell proliferation.Therefore, chemical compound of the present invention can be used for treating and suffers from the patient that tumor is characterised in that tumor sexual cell propagation.Chemical compound of the present invention also can be used for the disease of prevention and treatment TRX (thioredoxin)-mediation, for example autoimmune disease, allergia and inflammatory diseases, and be used to prevent and/or treat central nervous system (CNS) disease, for example neurodegenerative disease.
Background of invention
Chemical compound with hydroxamic acid part has demonstrated has useful biological activity.The for example known many Peptidyl compounds that contain the hydroxamic acid part suppress matrix metalloproteinase (MMPs), and it is for containing zinc endopeptidase family.Play an important role during the tissue of MMPs on the physiology and on the pathology is aging.Therefore, can suppress the disease that the active Peptidyl compounds of MMPs can be used for treating or preventing to relate to tissue decay and inflammation.In addition, to small part based on hydroxamic acid group and the bonded characteristic of zinc, the chemical compound that contains hydroxamic acid part has demonstrated inhibition of histone deacetylase (HDACs).
Express but suppress the HDACs repressor gene, comprise the gene expression relevant with tumor suppression.The inhibition of histone deacetylase can cause the transcription repression of tumor suppressor gene to histone deacetylase-mediation.For example, the inhibition of histone deacetylase can provide a kind of treatment cancer, hematologic disease (for example hematopoietic disease) and with the method for the metabolic disease of gene-correlation.More particularly, transcriptional control is the critical event in cell differentiation, propagation and the apoptosis.There are a plurality of evidences to show the transcriptional regulatory (Grunstein, M., Nature, 389:349-52 (1997)) of finishing cell by histone acetyl baseization and deacetylation mechanism.It is believed that these effects take place by the variation of chromatin Structure, this variation realizes the affinity of coiled coil type DNA in the nucleosome by changing histone.5 kinds of histones have been identified.Find histone H2A, H2B, H3 and H4 in nucleosome, H1 is the connector between nucleosome.Except that the H1 that separately exists in the nucleosomal structure outside, each nucleosome contains two kinds of histones wherein in its nuclear.Think that the affinity of histone and phosphoric acid DNA skeleton is bigger when histone hangs down acetylation.This affinity causes DNA and histone to be combined closely, and causes DNA to be difficult to transcription regulatory element and device.
Regulate the acetylation state by the active balance between acetylation of histone transferring enzyme (HAT) and two kinds of multienzyme complexs of histone deacetylase (HDAC).Think that low acetylation state suppresses relative dna and transcribes.Should low big polyprotein (large multiprotein) the complex catalysis of acetylation state by comprising the HDAC enzyme.Especially confirmed that HDACs catalysis removes the acetyl group on the chromatin nucleohistone.
Several examples show that the activity that upsets HAT or HDAC relates to the malignant phenotype and grows.For example, as if in acute promyelocytic leukemia, PML and α RAR merge the oncoprotein that produces and transcribe (Lin, R.J. etc., Nature391:811-14 (1998)) by raising HDACs inhibition specific gene.The tumor sexual cell can not be finished differentiation in such a way, and causing the leukaemia is hyper-proliferative.
United States Patent (USP) 5,369,108,5,932,616,5,700,811,6,087,367 and 6,511,990 disclose the hydroxamic acid derivs that can be used for the end differentiation eventually of selective induction tumor sexual cell, cell growth retardation or apoptosis, and these documents are combined in herein by reference.Except its biological activity as antitumor drug, think that recently these hydroxamic acid derivs can be used for the disease and the symptom for the treatment of or preventing various thioredoxins (TRX)-mediation, for example inflammatory diseases, allergic disease, autoimmune disease, with the oxidative stress diseases associated be characterized as the disease (U.S. Patent application the 10/369th of cell hyperproliferation, No. 094, on February 15th, 2003 submitted to, and the document is quoted by integral body and is attached to herein).In addition, think that these hydroxamic acid derivs can be used for treating central nervous system (CNS) disease such as neurodegenerative disease and are used for the treatment of the brain cancer (referring to U.S. Patent application the 10/273rd, No. 401, on October 16th, 2002 submitted to, and the document is quoted by integral body and is attached to herein).
Think and studies confirm that through the x-ray crystal analysis method, suppress HDAC with the chemical compound Vorinostat (SAHA) that contains hydroxamic acid and carry out (Finnin by catalytic site direct interaction with enzyme, M.S. etc., Nature 401:188-193 (1999)).Think that the result who suppresses HDAC does not have the universality effect to genome, but only influence genomic smaller subset (Van Lint, C. etc., Gene Expression 5:245-53 (1996)).The evidence that the little ordering of DNA (microarrays) that is with the malignant cell of cultivating with hdac inhibitor provides shows the gene of the limited quantity (1-2%) that its product change is arranged.For example, in culture medium, handle the inhibitors of kinases p21 (Archer, S.Shufen, M.Shei, A., Hodin, R. (1998) PNAS 95:6791-96) that the continuous induction cyclin dependent appears in cell with hdac inhibitor.This albumen plays an important role in suppressing cell cycle.Think that hdac inhibitor increases the p21 transcription rate by the high acetylation state that spreads histone in the p21 gene region, thereby make the gene can transcriptional machinery.It is expressed the gene that not influenced by hdac inhibitor and do not change (Dressel, U. etc., Anticancer Research20 (2A): 1017-22 (2000)) in the acetylation of zone association histone.
In addition, hydroxamic acid derivs for example SAHA can inducing tumor cell growth stop, differentiation and/or apoptosis (Richon etc., Proc.Natl.Acad.Sci.USA, 93:5705-5708 (1996)).These targeting compounds become the inherent mechanism of malignant cell ability, because they toxicity (Cohen, L.A. etc., Anticancer Research 19:4999-5006 (1999)) do not occur under the dosage that effectively suppresses the animal tumor growth.
Consider that the chemical compound that contains the hydroxamic acid part has application widely, therefore is starved of the hydroxamic acid derivs with improvement performance of development of new, the bioavailability of for example improved usefulness or increase.
Summary of the invention
The present invention relates to a kind of novel hydroxamic acid derivs with benzothiophene or thiophene skeleton.This hydroxamic acid compound can be used for treating cancer.But this hydroxamic acid compound is the inhibition of histone deacetylase also, and is applicable to the end differentiation eventually of selective induction tumor sexual cell, cell growth retardation and/or apoptosis, thereby suppresses this class cell proliferation.Therefore, chemical compound of the present invention can be used for treating the patient that the tumor of suffering from is characterised in that tumor sexual cell propagation.Chemical compound of the present invention also can be used for preventing and treats the disease of TRX-mediation, for example autoimmune disease, allergia and inflammatory diseases, and be used to prevent and/or treat central nervous system (CNS) disease, for example neurodegenerative disease.The present invention also provides the pharmaceutical composition that comprises described hydroxamic acid derivs and has easily comply with and made the safe dose scheme (dosing regimen) of the amount of proper interior hydroxamic acid derivs for these pharmaceutical compositions of treatment effective dose.

Alkylating agent
The for example reaction of the chemical entities on the nucleotide precursor that generates DNA of alkylating agent and nucleophilicity residue.They influence fission process by making these nucleotide alkylations and stoping it to be assembled among the DNA.
The example of alkylating agent includes but not limited to two chlorethamins (chlormethine is chlorambucil, cyclophosphamide, ifosfamide, chlormethine, melphalan, uracil mustard for example), ethylene imine (for example plug is for group), alkyl ketone sulphonic acid ester (for example busulfan), nitroso ureas (for example carmustine, lomustine, streptozocin), atypia alkylating agent (altretamine, dacarbazine and procarbazine), platinum compounds (carboplatin and cisplatin).These chemical compounds and phosphate ester, amino, hydroxyl, sulfydryl (sulfihydryl), carboxyl and imidazole radicals reaction.
Under physiological condition, these medicine ionizations produce the positively charged ion that is connected with protein with responsive nucleic acid, cause cell cycle to suppress and/or cell death.Alkylating agent is cell cycle phase non-specific (cell cycle phase nonspecific) medicine, brings into play their activity because they are independent of the concrete phase of cell cycle.Chlormethine and alkyl ketone sulphonic acid ester are the most effective to G1 or M phase cell.Nitroso ureas, chlormethine and ethylene imine influence are by G1 and the development of S phase to M phase.Chabner and Collins edit (1990) " Cancer Chemotherapy:Principles and Practice ", Philadelphia:JB Lippincott.
Alkylating agent has activity to multiple tumor disease, and treatment leukemia and lymphoma and solid tumor have significant activity.Clinically, this type of medicine is generally used for treating acute and chronic leukemia; Hodgkin; Non-Hodgkin lymphoma; Multiple myeloma; Primary brain tumor; The cancer of mammary gland, ovary, testis, lung, bladder, cervix uteri, head and neck and malignant melanoma.
Antibiotic
Antibiotic (for example cell toxicant antibiotic) works by direct inhibition DNA or RNA are synthetic, thus in whole cell cycle effectively.The example of antibiotic medicine comprises anthracycline (for example doxorubicin, daunorubicin, epirubicin, idarubicin and amerantrone), ametycin, bleomycin, actinomycin D and plicatomycin.The interference cell growth of these antibiotic by the different cell component of targeting.For example, it has been generally acknowledged that anthracycline disturbs the effect of DNA topoisomerase II in the zone of transcriptional activity DNA, cause DNA to unwind.
It has been generally acknowledged that the bleomycin chelated iron, and form activated complex, it combines with the base of DNA then, causes unwinding and cell death.
Antibiotic medicine as multiple tumor treatment of diseases medicine, comprises mammary gland, lung, the thyroid cancer of harmonization of the stomach, lymphoma, myelomatosis, myeloma and sarcoma.
Antimetabolite
Antimetabolite (being antimetabolite) is that a class is disturbed the physiological function of cancerous cell and the medicine of the vital metabolic process of propagation.The active cancerous cell of propagation needs constantly synthetic a large amount of nucleic acid, protein, lipid and other important cell component.
Many antimetabolite suppress purine or pyrimidine nucleoside is synthetic or the enzyme of inhibition dna replication dna.Some antimetabolite also disturbs ribonucleotide and RNA is synthetic and/or amino acid metabolism and protein synthesis.By disturbing important cell component synthetic, antimetabolite can postpone or the anticancer growth.The example of antimetabolite includes but not limited to fluorouracil (5-FU), floxuridine (5-FUdR), methotrexate, folinic acid, hydroxyurea, thioguanine (6-TG), mercaptopurine (6-MP), cytosine arabinoside, pentostatin, fludarabine phosphate, carat Qu Bin (2-CDA), asparaginase and gemcitabine.
Antimetabolite has been widely used in the cancer of the some frequent specieses of treatment, comprises the cancer, malignant melanoma of colon, rectum, mammary gland, liver, harmonization of the stomach pancreas, acute and chronic leukemia, hairy cell.
Hormonal medicaments
Hormonal medicaments is a class medicine of regulating its target organ g and D.Most of hormonal medicaments are sex steroid and derivant and analog, for example estrogen, progestogen, antiestrogen, androgen, antiandrogen and progesterone.These hormonal medicaments can be used as the antagonist of sex steroid receptor, and downward modulation expression of receptor and important gene are transcribed.The example of this type of hormonal medicaments has synthetic estrogen (for example diethylstilbestrol), antiestrogen (for example tamoxifen, toremifene, fluoxymesterol and raloxifene), antiandrogen (bicalutamide, nilutamide, flutamide), aromatase inhibitor (for example aminoglutethimide, Anastrozole and tetrazolium), luteinising hormone-releasing hormo (LHRH) analog, ketoconazole, goserelin acetate, leuproside, megestrol acetate and mifepristone.
Hormonal medicaments is used for the treatment of breast carcinoma, carcinoma of prostate, melanoma and meningioma.Because the main effect of hormone mediates by steroid receptor, so 60% receptor-positive breast carcinoma produces reaction to a line hormone therapy; And produce reaction less than 10% receptor-negative tumor.Progestogen are particularly useful for treating carcinoma of endometrium because these cancers occur in be exposed to progestogen can not the high-level estrogenic women of antagonism in.Antiandrogen is mainly used in the treatment carcinoma of prostate, and it is a hormonal dependent.They are used to reduce testosterone levels, thereby suppress tumor growth.
Hormone therapy breast carcinoma relates to the estrogen level that reduces dependence activation estrogen receptor in the mastadenoma sexual cell.Antiestrogen works by combining and prevent to raise coactivator with estrogen receptor thereby suppressing the estrogen signal.
The LHRH analog is used for the treatment of carcinoma of prostate, thereby reduce testosterone levels tumor growth is reduced.
Aromatase inhibitor works by suppressing the required enzyme of synthetic hormone.In postmenopausal women, estrogenic main source is by virtue enzymatic conversion androstenedione.
The plant origin medicine
The plant origin medicine is to derive from a medicine of plant or a class medicine of modifying on the molecular structure basis of these medicines.They assemble and suppress cellular replication by stoping pair cell to divide vital cell component.
The example of plant origin medicine comprises vinca alkaloids (for example vincristine, vinblastine, vindesine, vinzolidine and vinorelbine), podophyllotoxin (for example etoposide (VP-16) and teniposide (VM-26)), taxanes (for example paclitaxel and docetaxel).These plant origin medicines are usually identical with the effect of anti-mitosis medicine, and they combine with tubulin and suppress mitosis.Think podophyllotoxin for example etoposide cause DNA to unwind and disturb DNA synthetic by interacting with topoisomerase II.
The plant origin medicine is used to treat multiple cancer.For example, vincristine is used for the treatment of leukemia, Huo Qijin and non-Hodgkin lymphoma and pediatric tumor neuroblastoma, rhabdomyosarcoma and wilms' tumor.Vinblastine is used for lymphoma, carcinoma of testis, renal cell carcinoma, mycosis fungoides and Kaposi sarcoma.Confirmed that docetaxel is expected to have anti-advanced breast cancer, the activity of nonsmall-cell lung cancer (NSCLC) and ovarian cancer.
Etoposide has the activity of anti-multiple tumor, and wherein small cell lung cancer, carcinoma of testis and NSCLC are the most responsive.
Biological medicine
Biological medicine is to use separately or unite with chemotherapy and/or radiotherapy to cause the class biomolecule that cancer/tumor disappears and takes off when using.The example of biological medicine comprises immune modulator, for example the monoclonal antibody of cytokine, tumor-resistant antigen, tumor suppressor gene and Theratope.
Cytokine has extremely strong immunoregulatory activity.Some cytokine is interleukin-2 (IL-2, aldesleukin) and alpha-interferon (IFN-α) confirmation anti-tumor activity for example, and approved is used for the treatment of the patient who suffers from metastatic renal cell cancer and metastatic malignant melanoma.IL-2 is to the very important T cell growth factor of the cell-mediated immunoreation of T.Think that IL-2 is the immunoreactive result that has any different between cell-mediated oneself and the non-oneself to some patient's selectivity antitumor action.
Alpha-interferon comprises having the active relevant hypotype greater than 23 of stack.As if IFN-α confirms to have the activity of anti-multiple solid tumor and hematologic malignancies, and the latter is especially responsive.
The example of interferon comprises alpha-interferon, beta-interferon (fiblaferon) and gamma interferon (fiblaferon).The example of other cytokines comprises erythropoietin (α-erythropoietin), granulocyte-CSF (filgrastim) and granulocyte, macrophage-CSF (Sargramostim).Other acellular factor immunomodulators comprise bacillus calmette-guerin vaccine, levamisole and octreotide, act on the long-acting octapeptide of the hormone somatostatin of similar natural generation.
In addition, anticancer therapy can comprise the treatment of the immunotherapy of the reagent that uses antibody and the use of tumor inoculation vaccine method.Main medicine in this type of therapy is separately or for example carry toxin or chemotherapeutics/cancerous cell is produced the antibody of cytotoxic chemical compound.The monoclonal antibody of tumor-resistant antigen is the antibody that causes the antitumor antigen expressed, preferred tumor specific antigen.For example, propose to resist the human epidermal growth factor receptor 2 (HER2) of overexpression in some breast tumor, comprise metastatic breast cancer with monoclonal antibody HERCEPTIN (trastuzumab).The HER2 protein overexpression is relatively poor relevant with more aggressive disease and clinical prognosis.HERCEPTIN is used for the treatment of separately and suffers from the proteic metastatic breast cancer patient of tumor overexpression HER2.
Another example of the monoclonal antibody of tumor-resistant antigen is RITUXAN (Rituximab), and the CD20 and the selectivity that propose on its lymphoma sexual cell reduce normal and pernicious CD20+ pre B lymphocyte and mature B cell.
RITUXAN be used for the treatment of separately suffer from recurrence or intractable low level or folliculus, the patient of CD20+B cell non-Hodgkin's.MYELOTARG (Gemtuzumab Ozogamicin) and CAMPATH (alemtuzumab) are another examples of the monoclonal antibody of spendable tumor-resistant antigen.
Tumor suppressor gene is the gene that act as cell growth inhibiting and division cycle, thereby stops tumour development.The tumor suppressor gene sudden change causes cell to ignore one or more and suppresses the signal network composition, overcomes cell cycle chechpoint, and causes controlling the growth-cancer of cell more speed.The example of tumor suppressor gene comprises Duc-4, NF-1, NF-2, RB, p53, WT1, BRCA1 and BRCA2.
DPC4 relates to cancer of pancreas, and participates in suppressing fissional kytoplasm approach.The NF-1 coding suppresses the albumen of Ras, and it is the kytoplasm Profilin.NF-1 relates to neural neurofibroma and pheochromocytoma and myelomatosis.The NF-2 coding relates to the nucleoprotein of neural meningioma, schwannoma and ependymoma.RB coding pRB albumen, it is the main inhibitor nucleoprotein of cell cycle.RB relates to retinoblastoma and bone, bladder, minicell lung and breast carcinoma.The fissional p53 albumen of P53 coding and regulating, and can induce to transfer and die.Discovery is p53 sudden change and/or inactivation in multiple cancer.WTI relates to the kidney wilms' tumor.BRCA1 relates to mammary gland and ovarian cancer, and BRCA2 relates to breast carcinoma.Tumor suppressor gene can be transferred in the tumor cell that wherein can bring into play its tumor suppression function.
Theratope is to induce health tumor to be produced a class medicine of specific immune response.The most of Theratopes that are in research, exploitation and the clinical trial are tumor associated antigen (TAAs).TAAs is present on the tumor cell, and the structure (being albumen, enzyme or carbohydrate) that does not exist or reduce relatively on normal cell.Because quite unique to tumor cell, TAAs provides target for immune system recognition, and causes their destruction.The example of TAAs comprises the full cell or the part/lysate of antigen (MART-1, gap100, MAGE 1,3 tryrosinase), human papillomavirus E6 and E7 segment, autologous tumor cell and allos tumor cell that ganglioside (GM2), prostate specific antigen (PSA), alpha-fetoglobulin (AFP), carcinoembryonic antigen (CEA) (for example mammary gland, lung, harmonization of the stomach cancer of pancreas produce by colon cancer and other adenocarcinoma), melanoma are relevant.
Other therapies
Except that with traditional cell toxicant and the hormonotherapy treatment cancer, also introduce other therapies of the treatment cancer of newly-developed.
For example, the gene therapy of various ways is being carried out clinical preceding or clinical trial.
In addition, form the method that (blood vessel generation) suppresses in exploitation based on tumor vessel at present.The purpose of this notion is that tumors of nutrients and the oxygen supply that is provided by the new tumor vessel system that forms is provided.
