Description

The pharmaceutical composition and method for treating liver cancer
Technical field
The present invention relates to the pharmaceutical compositions and method for the treatment of liver cancer, and relate more specifically to through multiple inhibiting kinases group Or corresponding signal access and treat the pharmaceutical composition and method of liver cancer.
Background technique
Liver cancer is the current the third-largest fatal tumor in the whole world.It is divided into hepatocellular carcinoma (origin according to its pathological tissue source In liver cell) and bile duct cell liver cancer (originating from stones in intrahepatic bile duct cell), wherein liver cancer accounts for 80% of primary carcinoma of liver or more.Liver Cancer is process more than one, continues to develop variation, highly heterogeneous tumour.
Drug metabolism caused by the factors such as primary drug resistance and cirrhosis causes chemotherapeutic effect poor extremely, toxic side effect By force.Later period of hepatocarcinoma shifts, and mostly leads to liver function decompensation with cirrhosis, and the poor chemotherapy of patient body situation is not resistant to By, only be applicable in molecular targeted agents.Currently, molecular targeted class drug only has multiple target point kinase inhibitor Sorafenib (Sorafenib) it lists.Sorafenib is by inhibiting the signal paths such as RAF/MAPK/ERK, VEGFR, PDGFR, STAT3 to inhibit Tumor proliferation and new vessels generate, to achieve the effect that anti-liver cancer and anti-.But its clinical treatment outcome is unsatisfactory, only 2.5% liver cancer patient part improves, and complete cure rate is 0, and is only capable of extending 2.8 months overall survival phases.
Sorafenib treatment liver cancer mainly passes through target vascular therapy new life associated kinase VEGFR1/2/3 and PDGFR β and increasing Grow relevant Flt-3, c-Kit, RET and RAF/MAPK/ERK etc..Preclinical animal model research and clinical study results are shown Sorafenib plays antitumor action in vivo and mainly passes through inhibition vascular endothelial cell proliferation, and then blocks angiogenesis, Cut off the nutrition supply of tumor tissues.But Sorafenib clinically has certain toxic side effect, cause some patientss intolerant to By, and patient's overall survival phase that part responds only extends 2-3 months, has no and cures case completely.Cause Sorafenib clinical Ineffective reason has very much, mediates including liver cancer kinases reprogramming, anti-angiogenic rebirth drug resistance and EMT caused by heterogeneous Drug resistance etc..
Due to complicated processes such as the heterogeneous characteristic of tumour height and kinases reprogrammings, it is applied alone medicine effect not aobvious enough It writes, drug combination inhibits a plurality of signal path to be increasingly becoming a kind of common recognition simultaneously.The signal paths such as EGFR, mTOR, c-Met The advanced activation in liver cancer has clinically carried out Sorafenib and EGFR inhibitor Tarceva and mTOR inhibitors drug combination Research, but regrettably, it also fails to acquirement and is substantially better than the therapeutic effect that medicine is applied alone in Sorafenib.
Extensive genome research shows averagely there is 30-40 kind gene mutation in each tumour.And solve the problems, such as this Maximum challenge is to distinguish " trunk " mutation and " branch " gene mutation.Once it is determined that key gene then can targeted target To corresponding signal path.And the discovery of oncogene driving for liver cancer at present is relatively limited, in addition to Sorafenib not yet at Function exploitation is directed to the targeted therapy scheme of other important genes.
Liver cancer molecular targeted therapy research in there are following characteristics: 1) be different from ALK fusion non-small cell lung cancer and The oncogenes such as the breast cancer of EGFR mutation rely on tumour, and the numerous wild type kinase advanced activations of liver cancer participate in regulating cell increasing jointly It grows, causes to inhibit single access that cannot reach good tumor inhibitory effect;2) presently found important mutated gene is as pressed down Oncogene TP53 and oncogene β-catenin etc. are difficult to be directly targeted, and the gene of these unconventionality expressions causes respective kinase living Change exception, and then passes through the malignant phenotype that downstream signaling pathway maintains tumour.Therefore, the molecular targeted therapy in liver cancer is still at present The research of kinase inhibitor is focused on, has clinically carried out a large amount of kinase inhibitor and has tested, such as targeting EGFR Erlotinib, rich carried out for Buddhist nun and the Lei Molu monoclonal antibody for targeting VEGFR etc. of Tivantinib, card for targeting c-Met face The research of three phases of bed, but the effect is unsatisfactory).Main cause includes: that the kinases targeted in 1) research may not be driving Key kinases but with property kinases, 2) due to liver cancer height heterogeneity inhibit single kinases cause kinases reprogramming it is compensatory Property activate other kinases, 3) molecule parting of liver cancer is unclear, not can determine that the target user of drug.
Currently, anti-liver cancer and anti-research most importantly excavates driving gene as therapy target.A large amount of genome point Analysis has obtained gene unconventionality expression information abundant, this driving candidate gene that can be targeted to scientist's searching brings huge Big chance and challenge.What gene analysis technique was more clear discloses the heterogeneity of liver cancer, can detect in average each tumour To 30-40 gene mutation.The gene of unconventionality expression is roughly divided into that and proliferation related to proliferation is two kinds uncorrelated, and wherein frequency is most High includes CTNNB1 (26.3%), TP53 (27%) and TERT955.8%) is mutated, CCND1 (7.2%) amplification etc., these Relationship between gene and the poor prognosis of liver cancer not yet proves, and tumor suppressor gene etc. is difficult to target.
In addition, research discovery liver cancer in a plurality of proliferation associated signal paths advanced activation, including VEGF/VEGFR, PDGFR, FGFR, PI3K/AKT/mTOR, c-Met, RAF/MAPK/ERK etc., but mutation of important kinases etc. is rarely found.
Sorafenib targets the kinases such as RAF/MAPK/MEK/ERK, FGFR, PDGFR and VEGFR, be listed it is unique One molecular targeted agents, however fail the survival state for really improving most of liver cancer patient, only by patient's overall survival phase Extend 2.8 months.The successful listing of Sorafenib, pushed a large amount of targeting VEGF/VEGFR, PDGFR, FGFR, c-Met, The inhibitor of the kinases such as EGFR, IGF1R, PI3K/AKT/mTOR carries out clinical research.
Have nearly 90 kinds of kinase inhibitors at present and has carried out clinical research for advanced liver cancer patient.It has completed and just In clinical research up to 450 remainders of development, kinase inhibitor accounts for nearly the 70% of clinical trial total amount.But regrettably by The reasons such as invalid and poor resistance caused by primary or acquired resistance still fail to obtain gratifying progress.
For the tumour that the oncogenes such as non-small cell lung cancer of ALK gene fusion and EGFR mutation rely on, block ALK or EGFR can reach good antitumor action.However liver cancer is different, clinically count out can for single kinase inhibitor It can be that multiple genes is made to participate in controlling its destiny due to the height heterogeneity of liver cancer.Sorafenib and Yi Weimo in clinical research Department's (mTOR inhibitors), Tarceva (EGFR inhibitor) drug combination do not obtain good result yet, may in this prompt liver cancer There are Key kinases group, whole collective effect regulates and controls liver cancer growth, needs design and rational therapeutic regimen, while blocking multiple keys The activity of kinases realizes the inhibiting effect to liver cancer.
Therefore, this field need to identify the core kinases group in liver cancer to determine the target spot of the molecular targeted therapy of liver cancer, And thus design novel therapeutic and Intervention Strategy.

Embodiment 3: influence of the drug combination of kinase inhibitor to hepatoma cell proliferation
Since two methods of Gene intervention and micromolecular inhibitor effect prove to block single kinase activity ineffective Inhibit hepatoma cell proliferation, inventor studies the Key kinases group of regulation hepatoma cell proliferation and inhibits it to reach simultaneously Good result.As previously mentioned, kinases EphB3, TrkB, ALK, EphA3, EphA5, LTK, c-Met, EphB2 and FRK are at 8 plants Advanced activation in cell.
Four kinds of corresponding inhibitor Dasatinibs, GNF-5873, Ceritinib and SGX-523 permutation and combination are carried out first Drug combination (table 6).In general, the kinase inhibitor of 1 μM of concentration can significantly inhibit target active.Therefore, it is selected in experiment remote Lower than IC501 μM of dosage of value.The inhibiting rate highest of Ceritinib and Dasatinib drug combination as the result is shown, with three kinds of drugs Or the inhibiting rate of four kinds of combination therapies is suitable, is about 40% (Fig. 4).And GNF-5873 and SGX-523 do not play it is bright Aobvious proliferation inhibiting effect.
Next, Ceritinib and Dasatinib and other inhibitor drug combinations are acted on 72h.Color is auspicious as the result is shown ZIP177 and SMMC-7721 proliferation is significantly inhibited for tri- kinds of Buddhist nun, Dasatinib and AZD4547 drug combinations, inhibiting rate is respectively 67.4% and 76.4% (Figures 5 and 6).This shows that these three compounds are effective medicine group in ZIP177 and SMMC-7721 It closes.
Meanwhile it being tested in other six plants of cells QGY-7703, BEL-7402, HepG2, Hep3B, Huh-7 and SK-Hep-1 The conclusion (Fig. 7) is demonstrate,proved.This shows the combination of tri- kinds of Ceritinib, Dasatinib and AZD4547 drugs to inhibition liver cancer cells Proliferation has universality, and significant cell inhibitory effect is obtained in various hepatoma cell strains.
Also measure influence (Fig. 9) of three kinds of kinase inhibitor drug combinations to the proliferation of normal cell.
Embodiment 4: biological effect: Ceritinib, AZD4547 and Dasatinib drug combination induce cell apoptosis
The above results show that drug is applied alone and two kinds of drug combinations cannot effectively inhibit hepatoma cell proliferation.However, three Kind of kinase inhibitor Ceritinib, AZD4547 and Dasatinib drug combination can significantly inhibit hepatoma cell proliferation (Fig. 6 and 7).Further, biological effect caused by these three drug combinations is investigated.The biology of Proliferation Ability is caused to be imitated Should there are many kinds of, including cell-cycle arrest, Apoptosis, necrosis, cell ageing, cell autophagy etc..Act on 48h, streaming Cell art detection three kinds of drug combinations of discovery significantly induce SMMC-7721 and ZIP177 Apoptosis, and are applied alone and any two kinds Drug combination cannot be apoptosis-induced (Fig. 8 A).The three kinds of drug combinations of discovery of immunoblotting detection simultaneously significantly increase PARP With the cutting (Fig. 8 B) of Caspase3, Apoptosis effect is demonstrated in molecular level.
Embodiment 5: Key kinases of identification ALK, FGFR2, the EphA5 as regulation hepatoma cell proliferation
As discussed above, three kinds of kinase inhibitor Ceritinibs, AZD4547 and Dasatinib combination can significantly press down Cell Proliferation processed shows that the key molecule of regulating cell destiny is likely to cover in the target spot of three kinds of drugs.
Dasatinib has numerous target spots, including more than 70 kinases target spots.Firstly, Ceritinib and AZD4547 are joined With, while the gene in the Dasatinib target spot interference library of Raybio company customization is interfered.It interferes as the result is shown EphA5 and two kinds of drug collective effects significantly inhibit SMMC-7721 and ZIP177 hepatoma cell proliferation, and inhibiting rate is respectively 65.35% and 71.45% (Figure 10) is suitable with three kinds of combination therapies effects.This shows that EphA5 is up to sand in the present invention For the crucial target spot of Buddhist nun.
AZD4547 is FGFR familyselective inhibitor, targets FGFR1,2,3.Therefore the main target of AZD4547 in the present invention Point is FGFR2.
LTK and ALK very high homology.Ceritinib is double target drugs of ALK and LTK. The Human Protein LTK expression is faint in liver cancer as the result is shown for Atlas database analysis, and ALK expression is stronger.With siRNA by ALK and LTK respectively with FGFR2 and EphA5 joint knocks out.Knocking out LTK, FGFR2 and EphA5 does not significantly inhibit SMMC-7721 simultaneously as the result is shown With the cell Proliferation (Figure 11) of ZIP177.However, it is effective and inducing cell apoptosis to knock out ALK, FGFR2 and EphA5 simultaneously Inhibit cell Proliferation (Figure 12), shows that ALK is the target spot that Ceritinib plays a role in liver cancer.
Preliminary conclusion is obtained based on the above results, and ALK, FGFR2 and EphA5 are the key that regulation hepatoma cell proliferation swashs Enzyme.
The above experiment determines that ALK, FGFR2 and EphA5 are the core for regulating and controlling hepatoma cell proliferation in various hepatoma cell strains Heart kinases group.Inhibit these three kinase activities that can significantly inhibit hepatoma cell proliferation simultaneously, mainly passes through apoptosis-induced realization.
Embodiment 6: relevant downstream key signal access AKT, ERK and the p38 of identification ALK, FGFR2, EphA5 kinases
The above result shows that inhibiting ALK, FGFR2 and EphA5 to cause Apoptosis simultaneously.Associated downstream signal path needs Further investigate.PI3K/AKT, MAPK/ERK and p38 signal path are the signal of interest accesses in receptor tyrosine kinase downstream, Participate in modulating apoptosis in platelets and proliferation.Anaplastic lymphoma kinase ALK usually occurs point mutation, gene magnification or gene and melts It closes, and then activates downstream passages.ALK gene was found in Anaplastic large cell patients with non Hodgkin lymphoma for the first time before more than 20 years Recombination.With going deep into for research, ALK is had become for potential oncotherapy biomarker, and being includes non-small cell lung A variety of solid tumors and hemopathic therapy target including cancer etc..Non-small cell lung cancer of the scientist's discovery in 2007 in 3-7% There are ALK gene fusions in patient.This important discovery has pushed the early stage of the bis- target drug crizotinib of ALK/c-MET to face Bed test, and it is made successfully to list the non-small cell lung cancer for treating ALK gene fusion in short 4 years.ALK's swashs It is living to participate in the links such as modulate tumor survival proliferation.It is in clinical research there are many ALK inhibitor at present.ALK regulation Downstream be mainly MAPK/ERK, PI3K/AKT signal path.
Receptor tyrosine kinase Ephrin family is different according to its ligand affinity and extracellular fragment architectural difference is divided into two greatly Subgroup EphA and EphB.Reported discovery 9 EphA (1-9) members and 6 EphB (1-6) members at present, respectively with EphA and EphB family ligand binding.Eph receptor and Eph ligand binding activate downstream passages, and the interaction between mediated cell participates in The life processes such as modulating apoptosis in platelets, proliferation, angiogenesis, adherency and movement migration.Clinically, the activation of EphA5 and patient Tumour growth and poor prognosis are closely related.
Receptor tyrosine kinase FGFR includes three structural domains: extracellular fragment, single pass transmembrane structure and intracellular section.Its extracellular fragment Signal is passed in conjunction with ligand FGF intracellular, causes the signal paths such as downstream MAPK/ERK, PI3K/AKT, JAK/STAT living Change.The transmitting of its signal relies primarily on the realization of adaptor protein FRS, Grb2, Gab1 compound.Have now been found that 22 kinds of FGF ligands, Wherein combined respectively with receptor FGFR (1-4) for 18 kinds.The activation of FGF signal path has mediated tumor survival, proliferation, transfer, blood The significant process such as pipe new life and drug resistance.Report that FGFR2 advanced activation in liver cancer is related to patient's poor prognosis.
Based on this, to Ceritinib, AZD4547 and Dasatinib inhibit hepatoma cell proliferation downstream MAPK/ERK, MAPK/JNK/p38, PI3K/AKT, JAK/STAT signal path are investigated.Immunoblotting testing result shows that color is auspicious P-AKT, p-ERK and p-p38 expression are significantly inhibited for Buddhist nun, AZD4547 and Dasatinib drug combination, and to p-STAT3 and p- JNK expression does not make significant difference (Figure 13).This shows that Ceritinib, AZD4547 and Dasatinib drug combination may be by drawing Play the Proliferation Ability that liver cancer cells were lowered and realized in the expression of downstream AKT, ERK and p38 signal path.
In order to determine crucial downstream signaling pathway, by AKT inhibitor MK2206, ERK inhibitor Trimetinib and p38 Inhibitor Skepinone-L drug combination.Dosage be respectively MK2206 (1 μM), Trametinib (1 μM) and Skepinone-L(10μM).The results show that this three signal paths is inhibited to significantly inhibit hepatoma cell proliferation (Figure 14) simultaneously, Main pass through induces cell apoptosis realization (Figure 15).
To sum up, numerous kinases advanced activations in liver cancer cells are found in model in vitro, wherein ALK, FGFR2 and EphA5 is the Key kinases for regulating and controlling hepatoma cell proliferation.Inhibit these three kinases can be by blocking AKT, ERK and p38 letter simultaneously Number pathway activity and induce cell apoptosis, thus inhibit liver cancer cell growth.
The common activation of embodiment 7:ALK/FGFR2/EphA5 is closely related with liver cancer poor prognosis
The above results show that ALK, FGFR2 and EphA5 universal advanced activation in hepatoma cell strain regulate and control liver cancer jointly Proliferation.Inhibit the activity of three kinds of kinases that can block PI3K/AKT, MAPK/ERK and p38 access in downstream simultaneously.In order into one Step probes into clinical meaning, has investigated activation situation and its and liver cancer of these three Key kinases in the liver cancer tissue of liver cancer patient The correlation of the prognosis of patient.
Firstly, whether activation of the three kinds of kinases of detection in liver cancer cells and normal liver cell be variant.The results show that In 8 plants of liver cancer cells, the expression of p-ALK, p-FGFR2 and p-EphA5 are apparently higher than the Human normal hepatocyte QSG- in immortalization In 7701 (Figure 16).Further, the activity that three kinds of kinases freeze in liver cancer tissue and normal liver tissue at 24 Duis is detected.It was found that Activation levels of three kinds of kinases in liver cancer tissue are significantly higher than (Figure 17) in the normal tissue.
Immunohistochemical detection is the results show that in different liver cancer samples, the table of p-ALK, p-FGFR2 and p-EphA5 Up to different (Figure 18).The collective height activation (Figure 19) in about 13% liver cancer patient of three kinds of kinases.Kaplan-Meier Plotter analysis finds, the poor prognosis of the single activation of ALK, FGFR2 or EphA5 and liver cancer patient without significant correlation, And the overall survival phase for the patient that wherein three kinds of kinases activate jointly is considerably shorter than other subgroups (Figure 20), shows p-ALK, p- The common high expression of FGFR2 and p-EphA5 is positively correlated with liver cancer patient poor prognosis.Therefore, the present invention, which identifies, has than it The specific liver cancer patient subgroup of the worse prognosis of his subgroup, the wherein common high expression of p-ALK, p-FGFR2 and p-EphA5.
Embodiment 8: Ceritinib, Dasatinib and AZD4547 drug combination inhibit the growth of human liver cancer Nude Mice
The above results discovery tri- kinds of kinases of ALK/FGFR2/EphA5 regulate and control hepatoma cell proliferation jointly, refer to jointly downstream To AKT, ERK and p38 signal path.Western blot analysis and organization chip the immunohistochemical analysis discovery of patient tissue, ALK/FGFR2/EphA5 is activated jointly in about 13% liver cancer patient, and subgroup patient's overall survival phase is sub- compared to other Group is shorter.Synthesis shows that three kinds of kinases are the core kinases groups in liver cancer, can be used as the target spot of subsequent molecular targeted therapy.
Based on this, need further to study corresponding molecular targeted therapy strategy.Cellular level three kinds of kinases as the result is shown Inhibitor drug combination significantly inhibits hepatoma cell proliferation, before the program is to the clinical application of liver cancer treatment for further evaluation Scape, the in-vivo tumour for having selected human liver cancer cells Hep G2 Model in Nude Mice to investigate three kinds of kinase inhibitors inhibit Activity.4 administration groups are set, give Ceritinib 25mg/kg, 25 mg/kg and AZD4547 12.5mg/ of Dasatinib respectively Three kinds of combination therapies of kg and same dose.Control group gives equivalent carrier/solvent.It takes orally once a day, continuously gives Medicine 2 weeks.
The tumors inhibition activity for using individually 2 administration groups of Ceritinib and Dasatinib as the result is shown is very weak, Less than 10%.The tumor control rate that the administration group of AZD4547 is used alone is about 50%.Ceritinib, Dasatinib and AZD4547 drug combination obtains highest tumor control rate, is 80.5% (Figure 21).Prove Ceritinib, Dasatinib and The combination of AZD4547 obtains the significant preferably in-vivo tumour compared with the exclusive use of each drug in mouse model and inhibits Effect.

Susan Lindquist research team finds the kinase interactions of Hsp90 and 60% or more.Hsp90 and client The combination of albumen depends on its albumen thermal instability.And it is numerous the study found that the key that Hsp90 regulates and controls in different systems swashs Enzyme client protein is different.It is HER2, non-small cell lung cancer in breast cancer for example, being mainly c-kit in gastrointestinal stromal tumor In be EGFR and ALK, mainly BRAF in melanoma.Therefore the critical issue to be solved is exactly, in liver cancer system, Whether Hsp90, which passes through three kinds of Key kinases, influences the growth of liver cancer.
Multiple members of research discovery FGFR and EphA family, Susan Lindquist team are client's egg of Hsp90 It is white, while also turning out that ALK and Hsp90 interacts.Protein interaction data library data show Hsp90 and ALK, EphA and FGFR family protein, which exists, be combined with each other (https: //www.picard.ch).Hsp90 is mainly distributed in cytoplasm, on a small quantity The subcellular organelles such as nucleus and mitochondria are distributed in, and ALK, EphA5 and FGFR2 are memebrane protein.There are Hsp90 and ALK, The premise that EphA5 and FGFR2 are bound directly.
PU-H71 is the Hsp90 inhibitor for coming into clinical research, is inhibited and being incorporated into the N-terminal of Hsp90 point Sub- companion's circulation, blocks Hsp90 in conjunction with client protein.2012, Gabriela Chiosis team research discovery PU-H71 Specifically combine the compound of Hsp90 and cancer protein in tumour.For example, in BCR-Abl dependence chronic myelogenous leukemia In, BCR-Abl unconventionality expression, stability dependency is in Hsp90.PU-H71 alternative is in connection, without with wild type c- Abl is combined.Therefore, PU-H71 pearl is the ideal tools for studying client protein.
Firstly, investigating endogenous Hsp90 and ALK, FGFR2 and EphA5 in liver cancer cells using co-immunoprecipitation experiment Relationship.The antibody mediated immunity of Hsp90 and three kinds of kinases precipitating and PU-H71 pearl pull down the experimental results showed that Hsp90 and ALK, FGFR2 Exist with EphA5 and interacts.These three kinases are likely to the client protein (Figure 25 and 26) of Hsp90.
Ganetespib is the most fast Hsp90 inhibitor of current clinical progress, competitively combines the N-terminal of Hsp90 Structural domain, blocker molecule companion's cyclic process, to inhibit the combination of Hsp90 and client protein.Co-immunoprecipitation experiment shows The addition Ganetespib short time handles the combination (Figure 27) that can significantly inhibit Hsp90 and ALK, FGFR2 and EphA5.
Hsp90 inhibitor blocker molecule companion's cyclic process causes client protein not by normal process maturation.False folding Albumen will be degraded by ubiquitination and through proteasome pathway.In order to further verify client's egg that three kinds of kinases are Hsp90 It is white, while inhibitor intervention and siRNA interference processing are carried out to investigate the influence to three kinds of kinase protein stability.It is added not For 24 hours, 0.1 μM of dosage can be lowered significantly for the Hsp90 inhibitor Ganetespib effect of same concentration (0.01 μM, 0.1 μM, 1 μM) ALK, FGFR2 and EphA5 protein expression (Figure 36 B).0.1 μM of Ganetespib is added and acts on 6h, 12h, for 24 hours and 48h respectively, Effect 12h lowers three kinds of kinase protein horizontal expressions as the result is shown, completely inhibits protein expression (Figure 28 A) for 24 hours.RealTime- Various concentration Ganetespib effect does not make significant difference (Figure 28 B) to three kinds of kinases mRNA level in-site expression for 24 hours to PCR as the result is shown. Show that Ganetespib lowers ALK, FGFR2 and EphA5 expression by influencing protein stability.
Protease inhibitors MG132 is degraded by the effect blocks protein of protease inhibition body through the approach.In order into One step card ALK, FGFR2 and EphA5 degrade via proteasome pathway, and 10 μM of MG132 pretreatment 6h are added, abandons supernatant, adds Enter fresh medium to wash three times, adds 0.1 μM of Ganetespib effect for 24 hours.MG132 can be reversed as the result is shown Degradation (Figure 29) of the Ganetespib to ALK, FGFR2, EphA5.
Based on the studies above, experiment, micromolecular inhibitor intervention and MG132 are pulled down using co-IP, PU-H71 pearl and is reversed in fact Verify the client protein that bright ALK, FGFR2 and EphA5 are Hsp90.Showing can be by blocking the activity of Hsp90 to reach simultaneously Inhibit the effect of ALK, FGFR2 and EphA5.In next step by main examination Hsp90 to the regulating and controlling effect and regulation machine of Hepatocarcinoma Proliferation System.

2. discussing
2.1. therapy target is found
Since the micromolecular inhibitor Gleevec of targeting Bcr-Abl in 2001 successfully lists, antitumor research is opened point New era of sub- targeted therapy.Scientist Weinstein discovery in 2002 knocks out transcription factor c- in osteogenic sarcoma cell The phenomenon that Myc causes cell differentiation and apoptosis to generate, and this tumor development depends on some specific gene is known as " oncogene It relies on ".This discovery has greatly accelerated the development of molecular targeted therapy.Target the micromolecular inhibitor of ALK and c-Met Crizotinib enables new clinical research mode for the first time, and medication crowd is locked in the patient of EML4-ALK fusion, the drug From clinical research to successfully list only used it is 4 years short.Compared to first 41 years molecular targeted agents Gleevec used time, is one Kind greatly progress.Therefore, the driving gene for targeting " oncogene dependence " becomes the main research of clinically oncotherapy Direction.Wherein the clinical diagnosis and treatment of non-small cell lung cancer is successful model.
But liver cancer height is heterogeneous, signal path is intricate, not yet finds driving gene, this is to molecular targeted The exploitation of drug brings huge challenge.A large amount of genetic analysis result makes the gene more comprehensively recognized in liver cancer different Normal expression, it is TP53, β-catenin and reverse transcriptase of telomere that wherein the frequency of mutation is highest, cannot still be targeted at present, And driving gene common in other solid tumors such as ALK, EGFR and c-Met gene mutation rate in liver cancer is extremely low.It is comprehensive Many factors, anti-liver cancer and anti-molecular targeted agents carry out clinical research mainly or are directed to kinases, including anti-angiogenic rebirth at present The drug of c-Met, mTOR, FGFR, MEK and ERK of drug and targeting high level activation etc. is applied alone and drug combination.
Based on Status quo of clinical study, the present invention is mainly focused on overactive kinases in liver cancer.Receptor tyrosine kinase Chip detects the activation levels of kinases in liver cancer cells, it is found that the kinases activated in 5 plants or more cells has 17 kinds, and have no Mutation and amplification etc. are abnormal.This explains that specific kinase inhibitor is invalid to liver cancer and clinically kinase inhibitor to a certain extent The reason of failure.In view of the height heterogeneity of tumour, drug combination is important to block multiple important kinases to be increasingly becoming simultaneously Therapeutic strategy.
Kinases network is in the process of dynamic change in liver cancer, and random drug combination can not effectively play antitumor work With.Multiple drug combination clinical tests are caused to end in failure.In the present invention, tri- kinds of ALK, FGFR2 and EphA5 are found for the first time and is swashed Enzyme forms a core kinases group, controls the growth of liver cancer cells and transplantable tumor.Moreover, the common activation of three kinds of kinases and liver The poor prognosis of cancer patient is positively correlated, three kinds of kinases collective height activation, subgroup patient's overall survival in about 13% patient Phase is shorter.This result divides group to be of great significance for clinically liver cancer patient, is expected to become patient's diagnosis or subgroup Enrolled " predicting marker ".
2.2. therapeutic strategy is probed into
ALK/FGFR2/EphA5 is most important for the growth of liver cancer, while three kinds of kinases being inhibited to significantly inhibit liver cancer Internal outgrowth.The multiple target point drug of three kinds of kinases of exploitation while targeting is the promising approach for solving the problems, such as this.It has also needed The alternative strategy of effect.Hsp90 has become due to regulating and controlling the stability of most of tumor development associated kinase in order to which important resists Tumor targets, and it is especially effective for the tumour of kinase regulatory, carry out there are many Hsp90 inhibitor and has been merged for ALK Non-small cell lung cancer and clinical 2-3 phase of breast cancer of the HER2 positive study.The experiment proves that ALK in liver cancer, FGFR2 and EphA5 is the Very Important Person albumen of Hsp90.Block Hsp90 activity can by inhibit three kinds of Key kinases and under It swims signal path and effectively inhibits liver cancer growth.This also elaborates molecular mechanism of the Hsp90 inhibitor for liver cancer treatment, is it Application clinically provides theoretical foundation.Prior, the patient that p-ALK/p-FGFR2/p-EphA5 is activated jointly can To be the sensitive group of Hsp90 inhibitor, liver cancer target user is provided for Hsp90 inhibitor.
Generally, it present invention finds Key kinases group ALK, FGFR2 and EphA5 of regulation liver cancer destiny, verifies simultaneously The correlation of its activation and patient poor prognosis.Correspondingly, the present invention establishes the molecular targeted therapy plan for the subgroup Slightly, i.e., three kinds of kinase inhibitor drug combinations and Hsp90 inhibitor are applied alone.New side is provided for the molecular targeted therapy of liver cancer To with preliminary theoretical basis.
