Background technology
Since last century, sought to help the tomour specific molecule of better diagnosis and treatment human and animal cancer.Except those based on the virus induction cancer and comprise the cancer by the molecular structure of viral gene regulation, in the human cancer of most of types, be difficult to provide to definite evidence based on the tomour specific material of molecular structure data.Little about example based on the tomour specific molecule of novel molecular structure.Pernicious human nerve's glioma with other with the amplification of EGF-R ELISA molecule or change under the situation of potential relevant tumor (such as breast carcinoma and other human cancer), still have nothing to do in the clearly demonstration of structural change molecule with unique sequences.
EGF-R ELISA (EGFR) is 170 kilodaltons (kilodalton) the membrane glycoprotein product of proto-oncogene c-erb B.The sequence of known EGFR gene (people such as Ullrich, 1984).“Human?EpidermalGrowth?Factor?Receptor?cDNA?Sequence?and?Aberrant?Expression?of?the?AmplifiedGene?in?A431?Epidermoid?Carcinoma?Cells.”Nature?309:418-425)。The EGFR gene is cell homologue people (1984) such as () Downward of the erb B oncogene discerned in avian erythrocytes increase disease virus at first."

The EGFR variant is followed the EGFR gene to amplify by gene rearrangement and is caused.There are eight kinds of main EGFr variants, be known as: (i) EGFRvI lacks most of extracellular domain of EGFR, (ii) EGFRvII is made up of the 83aa in-frame deletion in the extracellular domain of EGFR, (iii) EGFRvIII is made up of the 267aa in-frame deletion in the extracellular domain of EGFR, (iv) EGFRvIV contains the disappearance in the Cytoplasm domain of EGFR, (v) EGFRvV contains the disappearance in the Cytoplasm domain of EGFR, (vi) EGFR.TDM/2-7 contains the repetition of the exon 2-7 in the extracellular domain of EGFR, (vii) EGFR.TDM/18-25 contains the repetition of the exons 1 8-26 in the tyrosine kinase domain of EGFR, (viii) EGFR.TDM/18-26 contains the repetition (people such as Kuan of the exons 1 8-26 in the tyrosine kinase domain of EGFR, EGF mutant receptor vIII the treatment cancer in as molecular targets, Endocr Relat Cancer.8 (2): 83-96 (2001)).In addition, exist second kind of more rare second kind of junction point between exon 11 and 14 that have to introduce the EGFRvIII mutant of the disappearance of novel histidine residues (EGFRvIII/ Δ 12-13) (people such as Kuan, EGF mutant receptor vIII the treatment cancer in as molecular targets, Endocr Relat Cancer.8 (2): 83-96 (2001)).
EGFRvIII is at human cancer mesocuticle somatomedin (EGF) the receptor variant of common generation (people such as Kuan, EGF mutant receptor vIII in the treatment cancer as molecular target, Endocr Relat Cancer.8 (2): 83-96 (2001)).In the process that gene amplifies, 267 aminoacid deletion take place in extracellular domain, produce the novel junction point that the tomour specific monoclonal antibody can be pointed to.This variant of EGF receptor with ligand independently mode help tumor to send to develop by the composing type signal.Known EGFrVIII is not expressed in (Wikstrand on any normal structure, CJ. wait the people, " Monoclonal antibodies against EGFRvIII are tumorspecific and react with breast and lung carcinomas malignant gliomas.

Antibody structure
Known basic antibody structure unit comprises tetramer.Each tetramer is made up of the polypeptide chain of two pairs of unanimities, and each is to having one " light chain " (about 25kDa) and one " heavy chain " (about 50-70kDa).Amino-the end portion of each chain comprises main about 100 to 110 or more a plurality of amino acid whose variable region of being responsible for antigen recognition.Carboxyl-the end portion of each chain defines the main constant region of being responsible for effector function.Human light chain is categorized as κ and lambda light chain.Heavy chain is categorized as μ, δ, γ, α or ε, and the isotype of antibody is defined as IgM, IgD, IgG, IgA and IgE respectively.Be connected by about 12 or more a plurality of amino acid whose " J " district in light chain and heavy chain kind variable region and constant region, wherein heavy chain also comprises about 10 or more a plurality of amino acid whose " D " district.Generally see, FundamentalImmunology the 7th chapter (Paul, W. compiles, and the 2nd edition, Raven Press, N.Y. (1989)).The right variable region of each light/heavy chain forms antibody combining site.
Therefore, complete antibody has two binding sites.Except difunctional or bi-specific antibody, two binding sites are identical.
These chains are all showed the conservative relatively identical universal architecture of framework region (FR) that is connected by three hypervariable regions, are also referred to as complementary determining region or CDR.Each CDR to two chains compares by framework region, makes to be bonded to specificity epitope.To the C-end, light chain and heavy chain all comprise FR1, CDR1, FR2, CDR2, FR3, CDR3 and FR4 domain from the N-end.It is according to Kabat Sequences ofProteins of Immunological Interest (National Institutes of Health, Bethesda, Md. (1987 and 1991)) or Chothia ﹠amp that the aminoacid of each domain distributes; Lesk J.Mol.Biol 196:901-917 (1987); People such as Chothia, the definition among the Nature342:878-883 (1989).
Bispecific or bifunctional antibody be have two different heavy chains/light chains to the artificial hybrid antibody of two different binding sites.Bi-specific antibody can comprise that the fusion of hybridoma produces with the segmental method that is connected of Fab ' by multiple.See for example Songsivilai ﹠amp; Lachmann Clin.Exp.Immunol.79:315-321 (1990), people such as Kostelny, J.Immunol.148:1547-1553 (1992).The generation of bi-specific antibody is compared with the generation of conventional antibody and be can be relative labor-intensive technology, and the output of bi-specific antibody and purity are lower usually.Bi-specific antibody does not close the segmental form in site and has (for example, Fab, Fab ' and Fv) to have unijunction.Except the universal architecture aspect of antibody, the more special interaction between paratope and the epi-position can be checked by frame mode.In one embodiment, the CDR structure forms paratope, and antibody can be bonded to epi-position through it.The structure of this paratope can be measured in several ways.Can use traditional structural testing method, such as NMR or x-radiocrystallography.These methods can be checked independent paratope, or the structure when it is bonded to epi-position.Perhaps, molecular model can produce in computer simulation.Structure can be by means of commercially available encapsulation, and (San Diego, InsightII model encapsulation CA) produces by the homology model such as Accelrys.In brief, can utilize the check antibody sequence to seek the proteinic data base of known structure, such as, protein structure data base (Protein Data Bank).After identification had the homology protein of known structure, these homology protein can be used as model template.Each may template can be through comparison, produce in these templates sequence alignment thus based on structure.Can the antibody sequence of unknown structure and the comparison of these templates has unknown structure antibody with generation molecular model will be had subsequently.As be understood by those skilled in the art that, there is the multiple alternative method that in computer simulation, produces described structure, can use wherein any.For example, can use people such as being similar to Hardman, employing QUANTA (PolygenCorp., the Waltham of promulgation, Mass.) and CHARM (Brooks, B.R., Bruccoleri, R.E., Olafson, B.D., States, D.J., Swaminathan, S. and Karplus, M., 1983, J.Comp.Chem, .4:187) United States Patent (USP) U.S.Pat.No.5, the technology of technology described in 958, No. 708.
Not only whether the possibility paratope is bonded to epi-position to the shape of paratope and good degree is very important for measuring, and the interaction between epi-position and the paratope itself is the bulk information source of design variable antibody.As be understood by those skilled in the art that, there is this interactional mode of multiple research.A kind of mode is to use the structural model of possibility generation as indicated above, and use (Accelrys subsequently such as InsightII, San Diego, program CA), it has one can carry out the expansion module that Monte Carlo studies to configuration between paratope and its epi-position and space, location.The result can assess epi-position and interactional place of paratope and mode.In one embodiment, have only the fragment of epi-position or variant to be used to assist to measure relevant interaction.In one embodiment, whole epi-position is used for interactional modeling between paratope and the epi-position.As be understood by those skilled in the art that these two kinds of distinct methods have different advantages and deficiency.For example, only use the epi-position fragment to make and to carry out more detailed check to the possible variant of each side chain, and need not to expend the plenty of time.On the other hand, by only using the epi-position fragment, or only use epi-position to replace whole protein, the feature of the segmental feature of epi-position and whole epi-position may be different, therefore may be increased in and calculate the risk that misleads in the modeling process.In one embodiment, use two kinds of methods with the cross-check result with limited extent.In a preferred embodiment, if use the epi-position variant, but optimization is so that the epi-position variant comprises the most important residue of epi-position.The concordance of most important residue can be measured in several ways, for example described in example 4 of the present invention and 14.
Which by using the structure of these generations, can measure in the interaction of residue between epi-position and paratope most important.Therefore, in one embodiment, can be easy to select to change which residue change antibody in conjunction with feature.For example, apparent from extended model, the side chain of some residue can spatially stop the combination of epi-position in the epi-position, thus these residues is changed into the residue with less side chain unanimity.
This can measure in many ways.For example, two models of need observation are assessed the interaction based on functional group and adjacent group.Perhaps, as indicated above, the repeating groups that can carry out epi-position and paratope is right, to obtain more favourable energy interaction.These that also can measure multiple antibody variants interact and measure the alternative that antibody wherein can be bonded to epi-position.Also how the incompatible mensuration of various model group can be changed the antibody that antibody structure obtains to have required special characteristic.
The model of said determination can be tested by various technology.For example, interaction energy can measure with decision to need further which kind of variant of check by program discussed above.Use coulomb and Van der Waals to interact and measure the interaction energy of epi-position and variant paratope again.Also use and observe predetermined variation in the antibody structure at the site of sudden change and in fact whether can cause required variation in conjunction with feature.Perhaps, can change epi-position confirm that model is correct or be used to measure may between paratope and epi-position, take place generally in conjunction with theme.
Which kind of variation that the above-mentioned method that is used for modeling structure can be used for measuring protein structure will cause the specific required feature of antibody.In the protein structure which kind of be these methods can be used for measuring and change the required feature can not cause antibody.
As be understood by those skilled in the art that, although these models will provide necessary guide for forming antibody of the present invention and variant thereof, but still need carry out the conventionally test in the computer simulation model, may be by in vitro research.In addition, as be understood by those skilled in the art that any upgrading also can the antagonist activity have other seondary effect.For example, although expection causes bigger bonded change can cause bigger combination, can cause that also other can reduce or change the structural change of antibody activity.For whether being very common in the field under being determined at of this situation, and can measure in several ways.For example, in example 21, activity can be tested by ELISA.Perhaps, can come specimen by using the surface plasma body resonant vibration device.
The variant antibody of antibodies and confession excellent combination
In one embodiment, above-mentioned model is used to increase the binding ability of antibody to its epi-position.Antibody can be easier to be bonded to epi-position, and therefore has higher association constant (k a).Perhaps, antibody can dissociate from epi-position more slowly, and therefore has lower dissociation constant (K D), or the K of epi-position-paratope DTherefore be worth lessly, make that the combination degree between epi-position and the paratope is higher.
In certain embodiments, design variable antibody is with opposite feature combination.That is, antibody is not combined closely or not combination fast.
In other embodiments, the K of variant antibody DDifferent with the antibody of wild type, but variant antibody has more specificity for defined epitope.This means that the paratope through designerantibodies has the low risk that is bonded to other epi-position.Antibody can have the further feature that has changed.For example, variant to non-specific antibody in conjunction with having more immunity, even or when antibody exists with high concentration, in solution, still keep solvation.This variant can be present in the antibody of being discussed.For example, although hereinafter the higher concentration of Jian Yan some variant antibody caused in the Biacore experiment slower in conjunction with component (for example, 13.1.2mAb) described than slow component even some variant is not still showed under same concentrations, L217N-2.1 for example.Can form variant, and measure it subsequently after tested in fact whether with required feature combination by the model prediction of above measuring.Can select to have the mutant of big total interaction energy for further test with epi-position.Interaction energy can be measured in many ways, and one of them is as indicated above.
These variants can be tested in many ways.Exemplary selection comprises, and is not limited to KinExA (for example, the patent the 5th of Lackie promulgation, 372, No. 783, on December 13rd, 1994) (Sapidyne Instruments Inc., ID, Boise), surface plasma body resonant vibration (SPR) (e.g., BIACORE TMBiacore, Inc., Pistcataway, N.J.), arrhea fluorescent, resonant mirror and fluorescent polarization.Many these are selected not only can record data, and can be provided for data fitting be various theoretical curves and measure k thus a, k dAnd K DAnd the fabricated parts of other characteristic.Importantly, it should be noted that these curve fittings are that result data is not got rid of the probability that has some deviations.Therefore, relevant association, disassociation and equilibrium constant not only can be observed by these curve fitting mechanism, also can directly compare mutually according to those skilled in the art's knowledge.
The humanization of human antibodies and antibody
Human antibodies has been avoided and has been had the relevant problem of Muridae or rat antibody variable and/or constant region.The immunoreactive generation that the proteinic existence of these Muridaes or rat-derived can cause the quick removing of antibody maybe can cause resisting patient's internal antibody.For avoiding using Muridae or rat-derived antibody, can so that producing complete human antibodies, rodent produce complete human antibodies by the human antibodies function is introduced rodent.
Human gene's seat of megabasse size and the ability that is introduced into mice kind system are for illustrating greatly or providing strong approach through the function ingredients of the locus of original mappings and the useful model of generation human diseases among clone and the reconstruct YAC.In addition, use this technology that the expression and adjusting, they and the information transmission of other system and the related particular views that provides in disease is brought out and made progress thereof that its human equivalent can be the human gene's product between the period of development is provided the mice locus.
The important practical application of this strategy is mouse humoral immune system " humanization ".Human immunoglobulin (Ig) locus is introduced the sequencing of studying antibody that offered an opportunity in the mice of inactivation of endogenous Ig gene expresses and combination and the active potential mechanism in the B-cell development thereof.In addition, this strategy can be generation complete human monoclonal antibody (mAb)-a kind of important milestone in human diseases kind realization Antybody therapy prospect desirable source is provided.Expect that complete human antibodies can be minimised as mice or mouse-derived mAb with immunity and anaphylaxis essence, and therefore increased effect and the safety of giving antibody through throwing.Use whole mankind's antibody expection and can be the chronic and recurrent human diseases of treatment substantial advantage is provided, such as inflammation, autoimmunity and cancer, these all need to throw repeatedly and give antibody.
A kind of method at this purpose is that design is not enough to be used to have the mouse species that the big segmental mouse antibodies of human Ig locus is produced, to expect that these mices can produce the big instruction system of human antibodies under the situation of no mouse antibodies.Big human Ig fragment can keep the big variable gene multiformity and the suitable adjustable of antagonist production and expression.Be used for antibody variation and the mice instrument of selecting and for the shortage of human protein's immunologic tolerance, the human antibodies instruction system that reproduces in these mouse species should produce the antibody that all has (comprising human antigen) high-affinity for any interested antigen by employing.Use hybridoma technology, can be easy to production and selection and have the human mAb of required specific antigen-specificity.As 1994 disclosed, show this general strategy (seeing people such as Green, Nature Genetics 7:13-21 (1994)) in conjunction with first generation XenoMouse strain.The XenoMouse strain is designed to have the 245kb that contains human heavy chain locus and κ light chain gene seat respectively and the kind of 190kb size is the segmental yeast artificial chromosome of configuration (YAC), and it contains nuclear variable core constant region sequence Id.Contain the human Ig of YAC verified with reset compatible with the mice system of expressing and the replaceable mice Ig gene of inactivation that is for antibody.This can be confirmed by its human commands system and the human mAb ability of generation antigen-specificity that bring out the similar adult of B-cell development, the complete human antibodies of generation.These results show that also introducing contains the major part of the human Ig locus of bigger numbering V gene, other adjusting element and human Ig constant region can be summarized the complete instruction system in fact, and it is a feature with the human humoral response for infection and immunity.People's such as Green works extends to the human heavy chain locus of introducing the megabasse size respectively and the kind of κ light chain gene seat is a configuration YAC fragment by introducing greater than about 80% human antibodies instruction system recently.See people such as Mendez, No. the 08/759th, 620, Nature Genetics15:146-156 (1997) and U.S. patent application case applied for 1996 on Decembers 3.

Kirin has also shown produced human antibodies in mice, has wherein merged by microcell and has introduced large stretch of chromosome or whole chromosome.See European patent application the 773 No. 288 and the 843 No. 961.Xenerex Biosciences is is researching and developing a kind of technology that is used for potential generation human antibodies.In this technology, reconstitute the SCID mice with people's quasi-lymphocyte (for example, B and/or T cell).Mice is with after antigen immune, and the antigenic immunoreation that can create antagonism.See United States Patent (USP) the 5th, 476, No. 996, the 5th, 698, No. 767 and the 5th, 958, No. 765.
Human resisting-mouse antibodies (HAMA) reaction is with chimeric or other humanized antibody of commercial production guiding preparation.Although chimeric antibody has human constant region and Muridae variable region, still wish can be observed some human resisting-chimeric antibody (HACA) reaction, especially in chronic or many-dosage of antibody uses.Therefore, lost efficacy, still be desirable to provide whole person's antibody-like of antagonism EGFRvIII for the consideration and/or the influence that make HAMA or HACA reaction.
Antybody therapy
As if as described herein, the function of EGFRvIII antibody is very important at least a portion of its operator scheme.For example, with regard to function, the meaning is the activity of EGFRvIII antibody in operating with EGFRvIII.Therefore, in some aspects, wish that antibody fixedly fill-in also replenishes cytotoxic lymphocyte, participates in thus among CDC and the ADCC in conjunction with production of antibodies as the treatment material standed for that resists EGFRvIII.There is multiple antibody isotype, includes, but is not limited to following: Muridae IgM, Muridae IgG2a, Muridae IgG2b, Muridae IgG3, human IgM, IgG 1, IgG 3 and human IgA with identical function.Again, wish that antibody can activate the antibody-mediated cytotoxic reaction (ADCC) of dependence by the effector lymphocyte that the Fc receptor is engaged in such as natural killer (NK) cell in conjunction with production of antibodies as the treatment material standed for that resists EGFRvIII.But there is the antibody isotype of multiple ADCC, includes, but is not limited to following: Muridae IgG2a, Muridae IgG2b, Muridae IgG3, IgG 1 and IgG 3.Should be appreciated that the antibody of generation needn't have this isotype at the very start, but on the contrary, the antibody of generation can have any isotype and antibody can be the isotype of using the routine techniques conversion of knowing in this technology subsequently.These technology comprise uses direct recombinant technique (for example, seeing United States Patent (USP) the 4th, 816, No. 397) and cell-cell-fusion techniques (for example, see United States Patent (USP) the 5th, 916, No. 771 and the 6th, 207, No. 418).
In cell-cell technology, preparation has myeloma or other cell strain and another kind of myeloma or other cell strain with light chain of the heavy chain that contains any required isotype.These cells can be through merging subsequently, and the complete antibody of separable expression cell line.
For example, some anti-EGFR vIII antibody of this paper discussion is human anti-EGFR vIII IgG1 antibody.If this antibody has the required combination to the EGFRvIII molecule, isotype should be easy to conversion to produce human IgM, IgG 3 or IgG A, although still have identical variable region (it has defined specificity and some affinity thereof of antibody).These molecules (comprising IgG1) are fixing fill-in and participate in CDC subsequently, and if comprise IgG1 or IgG3 constant region, these molecules also can participate in relying on antibody-mediated cytotoxic reaction (ADCC) by replenishing cytotoxic lymphocyte.
Therefore, owing to produced the antibody material standed for that reaches required " structure " mentioned above attribute, therefore, it can have some required " function " attribute at least by the isotype conversion usually.The design of other treatment and generation
Based on the antibody activity that produces and characterize about EGFRvIII, promoted the design of other treatment form except that antibody moiety herein.
These forms include, but is not limited to senior antibody therapy (such as the therapy of bi-specific antibody, immunotoxin and labelled with radioisotope), the generation of peptide therapy, gene therapy, especially are interior antibody, anti-sensitization therapy and micromolecule.
For example, in conjunction with the generation of senior antibody therapy, wherein fill-in is fixing is desirable attributes with replenishing of cytotoxic lymphocyte, may kill by using bispecific, immunotoxin or labelled with radioisotope strengthen cell.
For example,, can produce and comprise following bi-specific antibody: (i) two kinds of antibody, a kind of specificity and another kind of specificity that has the second kind of molecule that combines that has EGFRvIII in conjunction with bi-specific antibody; (ii) chain has specificity to EGFRvIII and the second chain has specific monoclonal antibody body to second kind of molecule; Or (iii) has specific single-chain antibody for EGFRvIII and another kind of molecule.These bi-specific antibodys can use knows the technology generation, for example, in conjunction with (i) and (ii), for example see Immunol Methods 4:72-81 (1994) and above-mentioned Wright and Harris, and combination (iii), for example see people such as Traunecker, Int.J.Cancer (Suppl.) 7:51-52 (1992).Under each situation, second species specificity can be given Fc chain activated receptor, include, but is not limited to CD16 or CD64 (for example sees, people such as Deo, 18:127 (1997)), CD3 (Micromet ' sBiTE technology) or CD89 (for example see, people such as Valerius, Blood 90:4485-4492 (1997)).Bi-specific antibody according to aforementioned preparation may kill the cell of expressing EGFRvIII, and effective those cells of EGFRvIII antibody especially wherein of the present invention.
Binding immunoassay toxin, antibody can use the technology upgrading known in this technology and as immunotoxin.
For example see Vitetta Immunol Today 14:252 (1993).Also for example see United States Patent (USP) the 5th, 194, No. 594.In conjunction with the antibody of preparation labelled with radioisotope, these also can be easy to use the technology of knowing in this technology to prepare through upgrading antibody.For example see people such as Junghans, among the Cancer Chemotherapy and Biotherapy 655-686 (the 2nd edition, Chafner and Longo compiles, Lippincott Raven (1996)).Also see United States Patent (USP) the 4th, 681, No. 581, the 4th, 735, No. 210, the 5th, 101, No. 827, the 5th, 102, No. 990 (RE 35,500), the 5th, 648, No. 471 and the 5th, 697, No. 902.The molecule of each immunotoxin and labelled with radioisotope all may kill the cell of expressing EGFRvIII, and effective those cells of antibody especially wherein described herein.
But the quicker combination of designerantibodies, or slower in the epi-position disassociation, and therefore antibody itself can be designed to therapeutic agent.For example, antibody can be used for therapeutic agent is given in patient's throwing through changing feature.The treatment immune conjugate
As understand, kill expression and can pass through in the cell of the bonded molecule of specific binding molecules (such as antibody) specificity extremely useful deciding target with the bonded antibody of medicine, toxin or other molecule (immune conjugate or immunotoxin).As indicated above, unknownly as yet on any normal structure, expressed EGFRvIII.In addition, the EGFRvIII demonstration significantly is expressed in the multiple human tumor.Therefore, EGFRvIII is the molecule that attracts most attention that is used for deciding with immunotoxin target.
Occurred many about attempt specificity decide the report that target has the tumor cell of monoclonal antibody-drug conjugates (people such as Sela, among the Immunoconjugates 189-216 (C.Vogel, ed.1987); People such as Ghose are among the TargetedDrugs 1-22 (E.Goldberg compiles, nineteen eighty-three); People such as Diener are among the Antibody Mediated DeliverySystems 1-23 (J.Rodwell compiles, 1988); People such as Pietersz are among the Antibody Mediated DeliverySystems 25-53 (J.Rodwell compiles, 1988); People such as Bumol are among the Antibody Mediated DeliverySystems 55-79 (J.Rodwell compiles, 1988)).Cytotoxic drugs sees that with multiple Muridae monoclonal body combines such as methotrexate, daunorubicin, amycin, vincristine, vinblastine, melphalan (melphalan), ametycin and chlorambucil.In some cases, drug molecule is connected to antibody molecule, these intermediate supporting agent molecule such as blood albumin (people such as Garnett, Cancer Res.46:2407-2412 (1986) by intermediate supporting agent molecule; People such as Ohkawa, Cancer Immumol.Immunother.23:81-86 (1986); People such as Endo, Cancer Res.47:1076-1080 (1980)), dextran (people such as Hurwitz, Appl.Biochem.2:25-35 (1980); People such as Manabi, Biochem.Pharmacol.34:289-291 (1985); People such as Dillman, Cancer Res.46:4886-4891 (1986); People such as Shoval, Proc.Natl.Acad.Sci.85:8276-8280 (1988)) or polyglutamic acid (people such as Tsukada, J.Natl.Canc.Inst.73:721-729 (1984); People such as Kato, J.Med.Chem.27:1602-1607 (1984); People such as Tsukada, Br.J.Cancer 52:111-116 (1985)).
Adopt multiple connexon technology being used to preparing these immune conjugates, and studied dissociable and not dissociable connexon.Yet, under most of situation, if drug molecule can just can only be observed the complete cytotoxicity potential of medicine from being that the conjugate of non-upgrading form discharges deciding target site.
One of dissociable connexon that has been used to prepare antibody-drug conjugates is the acid-unstable connexon based on suitable-aconitic acid, and it utilizes the sour environment of different intracellular compartments, such as the endosome and the lysosome that run in the endocytosis of regulating at receptor.Shen and Ryser introduce the conjugate (Biochem.Biophys.Res.Commun.102:1048-1054 (1981)) that this method prepares daunorubicin and macromole supporting agent.Yang and Reisfeld use constructed anti--melanoma antibody (J.Natl.Canc.Inst.80:1154-1159 (1988)) that daunorubicin is coupled to.Recently, people such as Dillman also uses sour unstable connexon to prepare the conjugate (Cancer Res.48:6097-6102 (1988)) of daunorubicin and anti--T cell antibody in a similar manner.
Relate to by the another kind of method of people such as Trouet research daunorubicin is connected to antibody (Proc.Natl.Acad.Sci.79:626-629 (1982)) through peptide space arm.This is not carry out have the prerequisite that medicine discharges from this conjugate by the effect of lysozyme peptidase under.
Yet, disclosing in the cytotoxicity test in vitro, antibody-drug conjugates seldom reaches the cytotoxicity usefulness identical with free non-coupling drug.This shows, the mechanism poor efficiency that drug molecule discharges from antibody.In the scope of immunotoxin, the conjugate demonstration that the two sulphur bridges between monoclonal antibody and catalytic activity archon form has more cytotoxicity than the conjugate that contains other connexon.See people such as Lambert, J.Biol.Chem.260:12035-12041 (1985); People such as Lambert are among the Immunotoxins 175-209 (A.Frankel compiles, 1988); People such as Ghetie, Cancer Res.48:2610-2617 (1988).This is owing to the high IC of the favourable glutathion of effective disassociation of the cystine linkage between antagonist molecule and the toxin.However, only have on a small quantity about using two sulphur bridges to prepare the report example of the conjugate between medicine and the macromole.People such as Shen have described methotrexate and have been converted into mercapto buserelin derivant, then through cystine linkage and poly--D-lysine coupling (J.Biol.Chem.260:10905-10908 (1985)).In addition, one report has been described the preparation (people such as Menendez of the conjugate of the toxin medicine calicheamycin that contains trisulfide and antibody, Fourth International Conference on MonoclonalAntibody Immunoconjugates for Cancer, San Diego, Abstract 81 (1989)).Another report has been described the preparation (people such as Hinman, 53Cancer Res.3336-3342 (1993)) of the conjugate of the toxin medicine calicheamycin that contains trisulfide and antibody.
A reason that lacks the antibody-drug conjugates that disulphide connects is to have to contain the unavailability of cytotoxic drugs of sulphur atom that can be easy to be used for medicine is connected to through disulphide bridges the part of antibody.In addition, existing medicine is under the nondecreasing situation of its cytotoxicity potential, and it is difficult to carry out chemical modification.
The main deficiency of another of existing antibody-drug conjugates is that because of a limited number of relative appropriate cytotoxicity of deciding target antigen and static cancer drug (as methotrexate, daunorubicin and vincristine) it can not arrive the drug delivery of enough concentration decides target site.In order to reach significant cytotoxicity, be necessary a large amount of drug molecules directly or by polymerization supporting agent molecule is connected to antibody.Yet the antibody of these height upgradings shows usually for deciding combination and the in vivo removing from blood flow fast that target antigen weakens.
Maytansinoid is the height cytotoxic drugs.Maytansine is at first separated in the shrub tingia Folium Mayteni hookeri of East Africa by people such as Kupchan, and it shows the cytotoxicity (United States Patent (USP) 3rd bigger 100 to 1000 times than conventional cancer chemotherapeutic agents (as methotrexate, daunorubicin and vincristine), 896, No. 111).Found afterwards that certain micro-organisms also produced maytansinoid, such as the C-3 ester (United States Patent (USP) the 4th, 151, No. 042) of isovaleric acid maytansine ester and isovaleric acid maytansine ester.The synthetic C-3 ester of isovaleric acid maytansine ester and the analog of isovaleric acid maytansine ester (people such as Kupchan, J.Med.Chem.21:31-37 (1978) have also been reported; People such as Higashide, Nature270:721-722 (1977); People such as Kawai, Chem.Pharm.Bull.32:3441-3451 (1984)).The example of the analog of C-3 ester isovaleric acid maytansine prepared therefrom ester comprises on the aromatic ring (for example, dechlorination) or at C-9, C-14 (for example, the hydroxylating methyl), C-15, C-18, C-20 and C-4,5 places are through the isovaleric acid maytansine ester of upgrading.
Natural generation and synthetic C-3 ester can be divided into two groups:
(a) have simple carboxylic C-3 ester (United States Patent (USP) the 4th, 248, No. 870, the 4th, 265, No. 814, the 4th, 308, No. 268, the 4th, 308, No. 269, the 4th, 309, No. 428, the 4th, 317, No. 821, the 4th, 322, No. 348 and the 4th, 331, No. 598) and
(b) has the C-3 ester (United States Patent (USP) the 4th, 137, No. 230, the 4th, 260, No. 608, the 5th, 208, No. 020 and Chem.Pharm.Bull.12:3441 (1984)) of the derivant of N-methyl-L-alanine.
The cytotoxicity of the ester of discovery group (b) is more much bigger than the cytotoxicity of the ester of group (a).
Maytansine is a mitotic inhibitor.Reported and in vivo handled the L1210 cell with maytansine and cause 67% cell aggregation in mitosis.Reported undressed and shown mitotic index between 3.2% to 5.8% people such as (, 43 Comparative Leukemia Research 1975, Bibl.Haemat.495-500 (1976)) Sieber than pair cell.The experiment of sea urchin egg and Carnis Mactrae ovum shows, and maytansine disturbs microtubule to form to suppress mitosis people such as (, Science189:1002-1005 (1975)) Remillard by the polymerization that suppresses microtubular protein (tubulin).
In vitro, find with 10 -3To 10 -1The maytansine of μ g/ μ l dosage can suppress P388, L1210 and LY5178 Muridae leukaemia suspension, and wherein the P388 cell strain is the most responsive.Shown that also maytansine is the activity inhibitor that human nasopharyngeal carcinoma cell is in vitro grown, and report human acute lymphoblastic leukemia cell strain CEM can be by being low to moderate 10 -7The concentration of mg/ml suppresses people such as (, Biochem.Pharmacol.24:1735-1738 (1975)) Wolpert-DeFillippes.
In vivo, maytansine also shows to have activity.Be presented at the tumor growth that suppresses P388 lymphoblast leukemia system in 50 to the 100 multiple dose scopes, this shows to have high therapeutic index; L1210 mouse leukemia system, human Lewis lung cancer system and human B-16 melanotic cancer system also show remarkable inhibiting activity (Kupchan, Ped.Proc.33:2288-2295 (1974)).
The method of coupling maytansinoids and cell bonding agent (such as antibody) comprises two reactions steps at present.At first with cell bonding agent (for example antibody) with cross-linking reagent (such as N-succinimido pyridine radicals dithio propionic ester (SPDP)) upgrading the dithio pyridine radicals is introduced antibody (people such as Carlsson, Biochem.J.173:723-737 (1978); United States Patent (USP) the 5th, 208, No. 020).In second step, the reactive maytansinoid that will have mercapto ((is called N such as DMl in form 2 '-deacetylate-N 2 '-(3-sulfydryl-1-oxopropyl))-and maytansine) be added in upgrading antibody as initial reagent, cause the displacement of sulfo-pyridine radicals in the upgrading antibody, reach the generation (United States Patent (USP) the 5th, 208, No. 020) of the cytotoxicity maytansinoid/ antibody coupling matter that connects by disulphide.At United States Patent (USP) the 6th, 441, a process that is used for coupling maytansinoids is described in No. 163.
(Cambridge MA) can obtain immunotoxin technology based on Maytansinoid by ImmUnogen Corporation.Another kind of important toxin technology is based on the auristatin toxin.The aplysiatoxin Dolastatin 10 that Auristatins obtains derived from the sea hare by sea, the Indian Ocean is as effective cell growth inhibitory substance.See United States Patent (USP) the 4th, 816, No. 444 and the 4th, 978, No. 744.About other aplysiatoxin, also see United States Patent (USP) the 4th, 414, No. 205 (Dolastatin-1,2 and 3), the 5th, 076, No. 973 (Dolastatin-3), the 4th, 486, No. 414 (Dolastatin-A and B), the 4th, 986, No. 988 (Dolastatin-13), the 5th, 138, No. 036 (Dolastatin-14) and the 4th, 879, No. 278 (dolastatin-15).By the colleague of Dr.Pettit and Arizona State university separate and synthetic various auristatine derivants after tested and demonstrate the height toxicity of pair cell.See people such as Pettit, antitumor agent 337.Synthesizing of aplysiatoxin 10 structure upgradings.Anticancer Drug Des.10 (7): 529-44 (1995), people such as Woyke.Active and the back antifungic action in the extracellular of effective aplysiatoxin 10 structure upgrading auristatin PHE.AntimicrobialAgents and Chemotherapy.45:3580-3584 (2001), people such as Pettit.The activity specific of aplysiatoxin 10 and peptide derivant antagonism neogenesis cryptococcus.Antimicrobial?Agents?and?Chemotherapy.42:2961-2965(1998),Woyke。Development of the three-dimensional of microtubule and auristatinPHE are to the influence of microtubule globality and nuclear location during the neogenesis cryptococcus cell cycle.Submitted,Antimicrobial?Agents?andChemotherapy。

Can be used as the delivery vehicles that medicine or toxin is transported to specifically cell at the antibody of cell surface antigen.If the internalization of this antibody stimulator antigen, perhaps at medicine or toxin after the antibody fracture, medicine or toxin can cause the death of cell.This mechanism is used in animal or the patient body killing tumor cell specifically.The method that selection can conduct drugs to the antibody of cell is by the secondary cell toxicity test.In these trials, first antibody combines with cell surface and adding and medicine or the bonded second antibody of toxin.If the internalization of first antibody stimulator antigen, second antibody will be total to internalization, in case just medicine or toxin fracture cause cell killing.
Example 8 secondary cell toxicity tests
In following research, the EGFRvIII-specific antibody be used to with the glioblastoma cell line (H1477) of the bonded toxin of second antibody guiding glioblastoma cell line (H80) and EGFRvIII transfection.From human IgG of Pharmingen (BD Biosciences Pharmingen) mouse anti (cat#555784) and toxin A EFP (Seattle Genetics, Inc.) and maytansine (DM1, Immunogen Inc.) in conjunction with to produce mah-AEFP (anti-IgG of muroid-AEFP) and mah-DM1 (the anti-IgG of muroid-DM1).In conjunction with by the anti-IgG of the proteic goat of saporin, Hum-ZAP (TM, cat # IT-22-250, the anti-IgG of the goat of affinity purification-saporin albumen) be from Advanced Targeting Systems (San Diego, CA, U.S.A.).H80 and H1477 cell with the concentration plating of 1000 cells in the 10 μ l somatomedins of every hole on 96 orifice plates.After 24 hours, first antibody and second antibody are mixed at 1: 3, continuously 6 dilutions in aerial 1: 5.The first antibody of 100 μ l dilution and toxin second antibody mixture add in the hole of cell with the final initial concentration 0.1 μ g/ml of first antibody, the final initial concentration 0.3 μ g/ml of second antibody.Allow these dull and stereotyped continuation to cultivate 3 days.At the 4th day, add that (CellTiter-Glo reagent (cat#G7571) U.S.A.) is also read with fluorescent for Madison, WI available from Promega.Figure 11 A-111,12A-12I and 13A-13I show this result of experiment.In the special mAb test of most of EGFRvIII, relatively kill and wound with the antigen-specific that at the Hum-ZAP of H80 (embankment piece) is medium at HI477 (filling out circle).MAb XG1-131 and XG1-139 produce the antigen-specific secondary with mah-AEFP and kill and wound, and are using mah-DM1 more among a small circle.In the antibody of test, XG1-131 has better performance than 13.1.2, XG1-095, XG1-139, XG1-150, XG1-170, XG1-250 and XG1-211 at least in a record.IgG1 is used as negative control and antigen-positive cell (H1477) and antigen negative cell (H80) is compared.
The visual specific use of amount of the specific killing that needs and changing.In one embodiment, the minimizing of any possible cancerous cell all is enough.For example, the minimizing of 0-1,1-5,5-10,10-20,20-30,30-40,40-50,50-60,60-70,70-80,80-90,90-95,95-99 or 100% target cell will be enough.In another embodiment, the minimizing of desired destination cell quantity still is a non-specific destructive function of antibody combination.For example, if the non-specific target and the destruction of antibody are seldom arranged, only have that the antibody of 10% target cell decreased number/toxin combination may be just enough.For example, antibody/toxin mixture kills and wounds and is lower than 10% of non-target complex.Equally, specific amount will depend on specific needs and situation.Useful especially antibody be those to target cell (for example H1477) have high selectivity and with the target cell good combination.In one embodiment, target is EGFRvIII albumen or its fragment.In one embodiment, showed human or humanized, effectively internalization, to EGFRvIII albumen or its fragment antibody special, that closely link to each other and link to each other with EGFRvIII albumen or fragment with effective toxin.
Example 9 secondary cell toxicity tests
Except cell toxicity test, also in producing clonogenic assay, tested the EGFRvIII specific antibody.Special EGFRvIII antibody will with the bonded second antibody of toxin guiding EGFRvIII transfection glioblastoma cell line (H1477), toxin is released in cell, and has finally reduced the ability that cell proliferation forms the clone.Therefore, when cell when the firsts and seconds toxin antibody is handled the back by plating once more, the application of these EGFRvIII antibody-toxin produces the minimizing of clone's quantity.In this example, H80 and H1477 cell are by with the density of every hole 30,000 cells once more on plating to 6 flat board and incubated overnight.First antibody and secondary toxin antibody were with 1: 3 mixed.The final concentration of this mixtures of antibodies with first antibody 0.5 μ g/ml, second antibody 1.5 μ g/ml added in the suitable hole.37 ℃ of incubated overnight.After the cultivation, handle this toxin mixture suitably, and cell is therefrom separated with the 1x trypsin.Cell be counted and with the density plating of every plate 200 cells in 6 new orifice plates.Three duplicates of corresponding each processed group of plating.Cultivate these dull and stereotyped 2-3 weeks at 37 ℃, until forming clone and can be with the naked eye or microscopically identification.The sucking-off medium also added the 5M methylene blue 1 hour.Wash with water dull and stereotyped and the counting clone.Figure 14 A and Figure 14 B show this result of experiment.As seen, with regard to three kinds of EGFRvAIII antibody of test, mab-AEFP secondary toxin antibody has suppressed the clone and has formed.
Example 10 anti-EGFRvIII antibody (13.1.2)
Direct combination in the cell toxicity test
Combining by antibody and cell toxicity medicament direct provides the antibody can be with the further evidence of drug conveying to a tumor cell.In following example, direct and the auristatin E MMAE of EGRvIII antibody 13.1.2, combine (MMAE and AEFP are all available from Seattle Genetics and description to some extent hereinbefore) with AEFP by peptide bond, and close (DM1 is available from Immunogen and description to some extent hereinbefore) with the mercaptan bond with maytansine (DM1).In case in the cell of expressing EGFRvIII antigen H1477, add conjugate, just observe special cytotoxicity.The cell of antigen expressed H80 being is not is not only just being killed and wounded when being exposed to the antibody of unusual high concentration.The result who in Figure 15 A-15C, shows this test.
EGFRvIII antibody is the method that has superiority especially that is used for the treatment of with direct combination of medicine or toxin.Therefore, initial test shows that such combination causes expressing the specific killing of the cell of EGFRvIII really.
Anti-EGFRvIII antibody characteristic in example 11 bodies.
The optional method whether a kind of definite antibody can be transported to cytotoxic drug cell is an effect of estimating the growth of binding antibody human tumor in vivo.This example provides a kind of like this method.Become neuroglial cytoma at In vitro culture H1477, by the trypsin results, and such as hereinafter explanation be embedded in the matrigel.Subcutaneous injection 5,000,000 cells in female nude mouse, and allow tumor development to reach about 0.5cm until it 3Size.This moment is the animal random packet, and begins not have once hypodermic processing in 4 days with the binding antibody of indicating concentration.Result among Figure 16 shows that antibody 13.1.2 is when causing the degeneration of glioblastoma multiforme when combining with maytansine (dEGFR-DM1) or auristatin E (dEGFR-MMAE).If with the unconjugated medicine that equates together during administration, (group 2),, illustrate that body interior orientation tumor cell needs combining of antibody and toxin to not influence of tumor growth.
Above the animal model of Shi Yonging obtains by H1477 cell xenograft is injected nude mice.Not commensurability cell is together injected 8 all nu/nu female mices separately or with MATRIGEL, and the post analysis tumor was implanted in several days.From this was analyzed, it was 5,000,000 about 22 days in MATRIGEL cells that identification allows the cell quantity of about size tumor.Comprise group G8 in contrast, be used to show that killing and wounding is antibody specificity.Comprise group G7 as negative control.
Therefore develop and a following scheme that is used for toxin study:
The 1st day: implanted 8 weeks of 500 ten thousand tumor cells in MATRIGEL are female mice greatly.The 22nd day: such as table 11.1 displaying, handle with the antibody prodrug by per four days of I.V..

The method of extra butt joint model and preference pattern level prediction binding affinity
In other embodiments, above-mentioned example can carry out and the peptide of six amino acid length not only the time with the different length peptide, as long as comprise crucial in conjunction with residue in the peptide.For example, replace the six amino acid peptide of EEKKGN (SEQ ID NO:127), can use 7 amino acid peptides of EEKKGNY (SEQ ID NO:131).Can use the epi-position of any big or small peptide.In other embodiments, peptide is to be selected from following peptide: LEEKKGNYVVTDHC (SEQ ID NO:56), LEEKKGNYVVTD (SEQ ID NO:59), LEEKKGNYVVT (SEQ ID NO:132) and EEKKGNYVVT (SEQ ID NO:57).Can use between peptide or its variant of the section fragment that discloses here to any size between the full-length peptide.
Those skilled in the art should be appreciated that as described, exist additional amino acid can change the mode of peptide binding antibody.Not only the existence of additional amino acid allows to be formed between peptide and antibody and replaces and extra bonding, and extra aminoacid can change the structure of peptide and the antibody structure of antibodies peptide.Therefore, in one embodiment, can test the different length epitope peptide, for example the binding characteristic of EEKKGN (SEQ ID NO:127) and EEKKGNY (SEQ ID NO:131) with combine optimization.Not only peptide accurately describe peptide is done mutually than the peptide-antibody of long segment than long segment, and bond strength and being included in conjunction with the change of interior residue test allows about longer peptide, the extraneous information of being derived by data.
In addition, and may be and the complementary longer fragments of peptides of test, can carry out extra filtration step to select to dock accurately model.Extra filtration step can allow to filter in many butt joint models to seek the model consistent with available experimental data.
In one embodiment, filter and be based on good isolating epi-position cartographic data, for example the independent residue of test feature is in conjunction with overview, and described cartographic data is in relation to each amino acid whose calculations incorporated energy overview in the peptide.For example, 7 amino acid peptides can be used to select to contain similar butt joint model in conjunction with the energy overview in conjunction with the energy overview.In conjunction with the energy overview is the assignment that combines energy of each aminoacid and specific amino acids in the peptide, amino acid whose in conjunction with the overview of creating peptide, and it is in conjunction with energy according to each aminoacid in described model.For example, a given peptide that comprises aminoacid A and B in a butt joint model, wherein A have-5 in conjunction with energy and B have-20 in conjunction with energy, can have the overview of A1 () and B2 () at 5 o'clock at 20 o'clock.This overview can other docks the filtration of model with electing.For example, use this can cause the selection of other butt joint model as filtration or " template " in conjunction with the energy overview, if the peptide in candidate's model has the low relatively value that contributes to position A, and has the high relatively value (big negative value, higher absolute value) that contributes to position B.In an other embodiment, template needs extra restriction, and for example the value of position B is higher 4 times than the value of position A.
Can be in many ways with relatively in conjunction with the overview of energy overview template and peptide in other docks model.If with required to combine the energy overview similar, subsequent filtration can be used for further test as selecting favourable butt joint model so in conjunction with energy overview template.If in conjunction with energy overview template and the required energy overview dissmilarity that combines, subsequent filtration can be as eliminating unfavorable butt joint model so.In one embodiment, filter process comprises having favourable and unfavorable template in conjunction with energy, and filtration is used for selecting and gets rid of the butt joint model.Those skilled in the art exist many possible differences in conjunction with the energy overview with what understand as described, and therefore depend on different situations, can use many differences in conjunction with the energy overview.In one embodiment, can define in conjunction with the energy overview is that ad-hoc location has a series of high relatively templates in conjunction with energy in peptide.In a preferred embodiment, in conjunction with high empty template of energy and template selected in conjunction with the energy overview will be in the position 2,4 of peptide EEKKGNY (SEQ ID NO:131) or 6 places have relative high in conjunction with energy.In another embodiment, in conjunction with energy overview template in the position 2,4 of peptide EEKKGNY (SEQ ID NO:131) or 6 places have high relatively in conjunction with energy.In another embodiment, have at 3 places, position of peptide EEKKGNY (SEQ ID NO:131) in conjunction with energy overview template relative to energy.In above discussion, described position is doubly assigned as follows: E1, E2, K3, K4, G5, N6, Y7.
In one embodiment, filtration treatment at first is included in the contrast in conjunction with energy of K3 and K4 place.Selection causes that K4 in contrast to the higher relatively butt joint model in conjunction with energy of K3, screens out simultaneously to cause that K4 in contrast to the relatively low butt joint model in conjunction with energy of K3.Therefore, " high relatively " mean K4 in conjunction with energy greater than (negative value is bigger, bigger absolute value) K3.Then, in conjunction with energy overview template, filter the butt joint model again, this time, be chosen in the combination model that position 2,4 or 6 places have relative higher-energy, can remove other model simultaneously.Therefore, " high relatively " mean in peptide in the position 2,4 or 6 places in conjunction with energy than minimum in conjunction with energy height (bigger negative value, bigger absolute value).Therefore, in this embodiment, can following summary binding energy measure feature template: E1 can be any value, E2 should be bigger than minimum, and K3 should be less than K4, and K4 should be greater than minimum, G5 can be any value, and N6 should be greater than minimum, and Y7 can be any value.Therefore, as long as at least one (or K3) less than among E2, K4 and the N6 at least one, E1, G5 and Y7 can be any value.In another embodiment, " high relatively " can be set at as modelling or the definite standard value of experiment.In one embodiment, the butt joint model filters better important by first specific filtration resistance butt joint model by second.Should be appreciated that as one of ordinary skill in the art, do not need one after the other to carry out these two steps, and these two steps can be carried out simultaneously.
In addition, depend on peptide, antibody and in conjunction with condition, these overview templates of filter result can be different.Give this disclosure, one of ordinary skill in the art are especially referring to behind the example 14, and it is suitable for energy overview template to determine.For example, shown in table 14.1, there are some possible important residues in peptide in conjunction with 131 and 13.1.2 antibody.In 131mAb, position E2, K4, N6 and Y7 are important for specific peptide after tested.In 13.1.2mAb, position E1, E2, K4, G5 and N6 are important for specific peptide after tested.These important residues can be to be contained in establishment in conjunction with the residue in the energy overview template.As can clearly knowing, go out with example 14 to analyze thought different in conjunction with energy overview template for displaying in the example 39 from following discussion.
Example 39 is the lower versions of template preciseness, and it allows more model by the screening step.If, can further add needs so about E1 and G5 to the trees that reduce by the model of screening step.
What result and these changes that following example proof uses longer peptide how can change above proof can mean, and proof is used the above-mentioned filtration that is used to select specific butt joint model.
The epitope-antibody butt joint model of example 397 amino acid peptides
This example proof produces one group of butt joint model, and described model is at the complicated structural model in the CDR district of 13.1.2 for 7 residue peptide.In addition, this example proof is selected the method for a butt joint model on another butt joint model.At first, 7 residue peptide EEKKGNY (SEQ ID NO:131) structural model builds up in extended configuration, and packs interior Discover_3 module minimization of energy with the InsightII modelling.Then, this peptide structure is manual is positioned in the connection site to form initial assembling.The Docking module is carried out the MonteCarlo search subsequently automatically among the use InsightII in translation and revolution space.In docking operation, allow 5 dusts when other antibody residue is fixed, to move in conjunction with the residue in the groove.Peptide is limited in the 5 dust original positions.The specious structure that Monte Carlo search is found is then through stimulating annealing and energy minimization to reach the resulting complex structural model.Obtain 63 butt joint models altogether.
For each butt joint model, the energy of doing mutually in the peptide between antibody and independent residue calculates with Discover_3.Independent residue contribution overview in the epitope-antibody combination is examined to select and the consistent butt joint model of good segregation epi-position cartographic data anticipate i.e. " in conjunction with energy overview template ".63 19 of docking in the model have passed through this inspection.Shown in the table 39.1 that a typical residue separately is in conjunction with the energy overview.Consistent with epi-position cartographic data in the example 14, K4's is significant in conjunction with energy, and N6 and E2 are big.This is in conjunction with the practical work of energy overview template lay special stress on K4 greater than K3.This needs E2, K4 relative with N6 big in conjunction with energy overview also lay special stress on.In other words, E2, K4 and N6's is not in conjunction with energy minimum (minimum negative value or least absolute value) in the peptide in conjunction with energy.Residue is consistent with the epi-position cartographic data in conjunction with energy overview and example 14 of antibody 13.1.2 separately in table 39.17 residue peptide.

As be found in selected model in the example 39, represent among Figure 21, the butt joint models show some non-anticipating results.Although an interesting result is that residue E2, K4 and N6 are important in combination peptide as a whole, these not all amino acid profiles turn into to being contained in antibody and form the H-key.Showing that K4 is contained in forms two H-keys with Q95, this with K4 consistent in conjunction with the importance in energy overview and the overview template.Show that also the N6 simulation is with bonding Q98; Yet in this special model, E2 and step are presented at and form the H-key in the model.The interesting trend of a unanimity is most of being buried of each Key residues (for example E2, K4 and N6) that derives from conjunction with energy overview template, and therefore closely contacts with the antibodies groove.Therefore, the butt joint Model Selection can illustrate that these Key residues are important practical works, because itself and the closely mutually work of antibody.In addition, E1 may form hydrogen bond with W214.
Example 39 proves that also said method causes in conjunction with energy and K DBetween height relevant, this model of thinking that this method is created also allows the K of antibody-peptide complex DOptimization or at least the prediction.
As be found in the contrast of example 39 and example 19, and having some is important residues between two models, some residues only show in 7 aminoacid butt joint model, and some residues step in 7 aminoacid butt joint model shows it is important.For example, 7 peptide epitopes are presented at and create the H key between K4...Q95, K4...Q95, N6...Q98, G5...H31, Y7...H31 and Y7...W165.On the other hand, 6 peptide epitopes are presented at and create the H key between E2...Y172, K3...H31, K4...H31, N6...D33, N6...Y37 and N6...K55.As finding out from above-mentioned data, 6 and 7 amino acid peptide models are all emphasized the importance of H31, because two models all comprise the H31 that forms two hydrogen bonds with peptide.Although there is other possibility trend between two data sets, it shows that also mutual work of many combinations changes over 7 amino acid profiles from the six amino acid model.Yet these examples proof can detect variation owing to the epi-position size with these models, and therefore from the convergent-divergent that is as short as longer epitope peptide and step should be problem according to this disclosure.Existing aminoacid to prove that continuously its importance in many combination models allows therefore to depart from the importance of many mutual works, can be the more typical representative that longer peptide is done mutually than the small peptide model therefore.
Should be appreciated that as affiliated technical field technical staff, also can be applied to 7 amino acid peptide EEKKGNY (SEQ ID NO:131) about above discussion or the example of six amino acid peptide EEKKGN (SEQ ID NO:127), or any longer peptide.For example, example 20 can repeat the information of example 39, and it is by the improved antibody of site directed mutation generation appropriate design affinity.In addition, the result of use-case 39 can repeat example 21, then is by site directed mutation the appropriate design affinity to take place to attempt to improve antibody to test from example 20 isolating any new antibody.
In one embodiment, the result of use-case 39 is to redefine the mutual work zone between antibody and the peptide.For example, the paratope of EEKKGNY (SEQ ID NO:131) can be defined as and comprise and be predicted as with peptide other residue of doing (for example, residue 95) mutually on the antibody.Perhaps, as example 19, paratope can be defined as all residues in the 5 dusts butt joint peptide.Different proteic computer simulation affinity maturations.
Success in vitro obtains affinity matured antibody in many different researchs.Usually, the library that suddenlys change arbitrarily need make up by molecular biology method, and needs exploitation selection/Screening test with abundant clone with good combination ability.Selected variant needs purified to determine affinity subsequently.This process need carries out a series of length and arduous experiment.Following example has proved by utilizing the selection possible accuracy prediction affinity maturation of antibody-antigenic complex structure separately.
Example 40 is by the computer simulation affinity maturation of antibody-antigen in conjunction with thermodynamics emulation
This example proves that the analog antibody-antigen that can use a computer is used for affinity maturation in conjunction with thermodynamics emulation.This example proves that especially Fab-12 (the IgG form is known as rhuMAb VEGF) and the power that combines of VEGF (microtubule endothelial cell growth factor (ECGF)) can be by the predictions of aforementioned calculation machine simulation process.
The VEGF-Fab complex crystal structure that uses and has accession number 1BJ1 in the PDB data base, it is resolved at 2.4 dusts.Use the experiment affinity data of delivering of a series of mutons of anti-VEGF Fab to be used to test viewpoint.The 3-D of the VEGF-Fab structure thing that matches is used for the computer simulation sudden change of following muton: H97Y, S100aT, T28D, 28D31H, 28D31H97Y100aT, N31H, Y53W, 71I73K, 71V73V.Described affinity data is from Chen, people such as Y (J Mol Biol., 293 (4): 865-81 (1999)) obtain.Between many VEGF-Fab mutons, carry out thermodynamics emulation as example 39 is described.The results are shown in the table 40.1.Result's proof of this example has obtained in conjunction with the significant correlation between energy and affinity row by this process.Figure 23 shows the suitable in detail logarithm to relative affinity in conjunction with energy.-0.91 correlation coefficient is illustrated computer mould emulation and is swashed accurately to catch in detail mutually at atomic level and do.
Table 40.1 antibody-antigen is in conjunction with energy emulation contrast affinity data.

As can clearly understanding, can infer that emulation identifies the higher affinity sudden change do not use ex vivo experiment from above example.In addition, this method obviously is useful for different antibodies and different peptides.Only use the high antibody-antigenic complex structure of resolving, this method can be applied to carry out the affinity maturation computer simulation usually.In one embodiment, this simulation affinity maturation that uses a computer will be saved the time and the resource of huge amount.
Example 41 standard antibody-likes are determined
People such as Chothia have described antibody structure (the J.Mol.Biol.1987 Aug 20 of the basis " standard class " of the hypervariable region of each immunoglobulin chain; 196 (4): 901-17).Analyze the Fab and the segmental atomic structure of VL of panimmunity globulin, with the relation of the three dimensional structure of determining aminoacid sequence and its antigen binding site.In present its packing of Crinis Carbonisatus such as Chothia, have the main few relatively residue that the hypervariable region main chain is constructed of being responsible for, its hydrogen bond or ability present abnormal phi, psi or omega structure.Find these residues occur in the hypervariable region the site and in conservative beta-thin slice frame.Passing a test has the immunoglobulin sequences of unknown structure, and people such as Chothia show that many immunoglobulins have hypervariable region, and these hypervariable regions have similar size to known structure, and additionally contains same residue in the site of the observed structure of load.
It finds that these hypervariable regions of hint have the structure close with known structure.For 5 hypervariable regions, the demonstration of all constituents of structure is limited to relatively small number purpose discrete topology class.What these main chains that hypervariable region takes place were usually constructed is term " norm structure ".People such as Chothia (Nature.1989 Dec 21-28; 342 (6252): 877-83) and other (Martin waits people J Mol Biol.1996 Nov 15; 263 (5): further work 800-15) confirms 5 main chain structures that have the sub-fraction all constituents of 6 hypervariable regions of antibody at least.
Analyze some above-mentioned antibody to determine the standard class of each complementary antibody determining area (CDR).As known, only the standard class is distributed to the CDR1 and the CDR2 of heavy chain of antibody, and the CDR1 of light chain of antibody, CDR2 and CDR3.Following table (41.1) has been summed up analysis result.Standard class data are the forms with * HCDR1-HCDR2-LCDR1-LCDR2-LCDR3, and wherein " HCDR " refers to that heavy chain CDR and " LCDR " refer to light chain CDR.Therefore, for example, a class standard 1-3-2-1-5 refers to have HCDR1 and falls into standard class 1, HCDR2 and fall into standard class 3, LCDR1 and fall into standard class 2, LCDR2 and fall into the antibody that standard class 1, LCDR3 fall into standard class 5.
