Other con~ iQnC chara~.~d by u.ldesll~d metallopr~tease activity include p~.iodun~ disease, epid~,.-.lol~;s bullosa and scleritis. In view of the involvement of n~r~ roteases in a number of disease con~;t;onc~ c"~plc have been made to prepare inhibitors to these e~l..es. A number of such inhibitors are ~i~,losed in the literature.

Inhibitors of r~tslloprot~a3es are useful in ll~dtillg ~i~r~5 caused, at least in part, by breakdown of structural proteins.

DETAILED DESCRIPTION
As used herein, the terms "protein," "protease," and "metalloprotease" refer to a ~licintegrin. ~lerelably this is a human riicinte~in as desc.il,ed below.
The term "antibody" refers to an ~llibody to a rliQ;'te~in, or fragment thereo~
These many be molloclonql or polyclonal, . nd can be from any of several . ources. The invention also co~m .~pl~c5 L~ e.-l~ of these antibodies made by any method in the protein or peptide art.
The term "disease screen" refers to a screen for a disease or disease state. A
disease state is the physiole~r-s-l or cellular or b:cchenlical ..-9 .;~ ~,t~l;on of the disease.
îc~bly this screen is used on body tissues or fluids of an animal or cell culture, using ~and~d techniques, such as ELISA. It also Co~ 9~'eS "~"~pp- ~g~ of disease in a whole body, such as by labeled antibody as desc,il,ed above given ~ r~lly regardless of the detectio~ m.otho-l, preferable such detectio~ .od~ include fluoi~s~encç, X-ray (inchl~li~ CAT scan), N~ (Tnr~ li~ MRI), and the like.
The term "cGl"po~md screen" is related to the ...~.lho~ls and screens related tofinding compounds, determining their affinity for the protease, or decigr.i~ or se~e~ g co"l~)ollnds based on the screen. In another Pmho~ nt~ it co.~- .pl~es the use of the three dimensional structure for drug design, preferable "rational drug design", as undc.~lood by the art. It may be pl~.f~ cd that the prote~ is in "es~ ly pure form", which refers to a protein re--o~-~ly free of other impulilics, so as to make it useful for cA~e~im~ls or chara~ ion. Use of this sel~,ning method assists the skilled artisan in finding novel structures, whether made by the chemist or by nature, which bind to and preferably inhibit the protease. These "inhibitors" may be useful in re~Jl~tin~ or moch ting the activity of the protcase, and may be used to thus mod~ te the b-olo~
cascade that they fi-nctiQn in. This appl.a-h affords new pha, - eutiçslly useful compounds.
The term "disinte~in" refers to a diQ;nte~g~in, a fragment thereof, a mutant thereof or a homnl~-e which still retains its fi~nCtio~ This term conlen~ es aggrn-qr~qse, and other p~ot~s which are involved in or modul~e tissue r~mr)dellin~ This conte-..p!~es ~iQ~ .If~ins from di~cling, species, and those prepar. d by recol.lbinanl m~thodc, in vitro m~thod5, or ~landald peptide ~l~thes;s. Preferably the protein is a human dic; ~leg~in or mutant thereof. For the purposes of ~fini~ the mut~ntQ~ of the protein the p~cÇcl~,d W O 97/31931 PCT~US97/03217 "native" protein is described in t~nR~ accession # Z48579, inco.~lo.~led herein by r~;rer~. ce and le~.red to in the seqllPnce below. SEQ ID NO 1 de,s~ es a fragment of that DNA sequence and its transcript and SEQ ID NO 2 describes the coding region of the gene and its l-~ns~,-ipt. Homologue d;C n~ ;nS include whole proteins with at least 90% homology as unde.~lood by the art, Ot ~iAgJ~ r~S thereo~ For exarnple, a ratprotein which is 95% homologous to that of SEQ ID NO. I or SEQ ID NO. 2 based onthe peptide sequence derived from the DNA or cDNA se~Upnce~ and a bovine protein~5i.,~il&,1y derived) being 97-98% homologous, are both conQ;de~ed homologuPs Thus homologous cDNAs cloned from other o~ n~ s give rise to homologous proteins.
Likewise pr~te.ns may be co-- de~ed homolcel~es based on the amino acid sequenre alone. Practical lin.;~ ;ol-~ of amino acid seq~lencing would allow one to d.,tel.-une that a protein is homologous to another using for ~ rle Co~l~yaliSOn of the first 50 amino acids ofthe protein. Hence 90% l~nlol~gy in would allow for 5 di~,.ing an~ino acids in the chain of the first 50 amino acids of the hon~f ~OgO~lS protein.
The skilled artisan will al,p,~,~,;ate that the de&_ne~_ ~ of the genetic code provides for dilrt;ling DNA sequences to provide the same l.ans_~ipt, and thus the sarne peptide. In certain cases pr~_paring the DNA seq~eneç, which encodes for the same peptide, but differs from the native DNA include;
~- ease of seq~pn~;ng or synthesis;
--- ine,~sed e,.prejiion of the peptide; and .,f~,rence of certain heterologous hosts for certain codons over others.
These practical conQ;~Ierations are widely kno~,vn and provide elllbo-J; ~.. nls that may be adv~ ~t~eQus to the user of the invention. Thus it is clearly cont~Q"..p~ ed that the native DNA is not the only ~--, bod:- n~ envisioned in this invention.
In r ~itiQn it is ap~e,.lt to the skilled artisan that L~ ne .-l c of the protein may be used in screening, drug design and the like, and that the entire peptide may not be r~uir~ for the ~ oses of using the invention. Thus it is clearly conte..~ ted that the skilled artisan will unde-~L~nd that the ~icrlosvre ofthe peptide and its uses contemplates the useful peptide fr~ ntc The practical consid~,lalions of protein c.~l)re~.;on, purification yield, stability, solLhility, and the like, are cor~;dç~ed by the skilled artisan when choo~;l.g ~~fLelher to use a ~ 1 and the fi~"l~ to be used. As a result, using routine practices in the art, the artisan can, given this disclosure p. ~.c~ice the invention using rl ag...~ ~1 s of the protein as well.
s The protein or pro~ease itself can be used to determine the binding activity of small ms~le~ules to the protein. Drug scle.,.~il 8 using enymatic targets is used in the art and can be employed using all~o...aled, high throughput technologies.
The inh;bition of dicinte~in activity may be a predictor of efficacy in the l-c~n.~-~of oste-oa-llu;lis, and other d ~ ACe~: involving dege~c~alion of articular cartilage.
Gene therapy Without being bound by theory it is thought that the metalloprotease is up regulvsted during osteoarthritis in tissues. We have SII~ u~gly found that a human ~lisintegrin is up-re~ ed in human chond.o~,~rtes during o~leoa.lluilic conAitionc Inhibition of signal trncd~ctiQn ...ech~ .. is cn.c~cio -c in dis.u~)th~g the rqccade of events in osteo~lluilis and other A;cç~c~s involving ca.lilage degene.alion. The skilled artisan will ~cco~uLe that if up-re~llAtion is a cause of the onset of arthritis, then interfering with the activity ofthis gene may be useful in treating oslfJoa-lluilis.
This is done by any of several ~ hod~ inclu~ii~ gene (i.e., A~-1 ;~n.~) therapy.Inhibitors of the f~ f ~y ;n The plo~ease of the invention can be used to find inhibitors of the prot~.
Hence it is useful as a scree~ng tool or for rational drug design. Without being bound by theory, the protease may modulate cellular rc.n~ g and in fact may enhsnce extracellular matrix ren od~ling and thus e-~h~r~ee tissue breakdo vn.. Hence inhib;tion of tegrin provides a ~ peulic route for ll~ nl of diC~F,5 chara.,lcliLcd by these ~. ~c~ss~,s In sc.-,~fing, a drug compound can be used to dct.,...une both the quality and quantity of inhibition. As a result such scr~lullg provides i~lfu~ alion for selection of actives, preferably smaD c'~cule actives, which are useful in ~l~,aling these diseases.
In therapy, inh:bifion of ~ 1c~yin me~s~cp~ulease activity via binding of small sr weight, ~.l~h~,lic metalloplote~e inhibitors, such as those used to inhibit the matrLx m_taUoproteases would be used to inhibit ~"~ll r~ ls~ matrix remodPIing L~libodies to the protein Metalloprûl~s active at a puticululy undesired loc~ion (e.g., an orgul or certain types of cells) can be lalg~led by ~ u l, g,gti~ a metallop, .,l~sc inhibitor to a to an untibody or fragment thereo~ Conj--8,s-tion rnetho-lc ue known in the art.
The a.l~il,od~ of the invention CUI also be conjugated to solid s.~ )G.ls. TheseconJIlgates can be used as affinity ,~,ag~ s for the purifi~iQn of a desired metalloprotease, preferably a ~ e~,u~.
, In another aspect, the antibody of the invention is directly conjugs-ted to a label.
As the antibody binds to the metallop~oteas_, the label can be used to detect the p~sence of relatively high levels of metalloploteast in vivo or in vitro cell culture.
In addition, the metallopro~ease inhibiting conlroun~s can be cor~ ated to antibodies. Typical conjugation metho~c are known in the art. These antibodies are then useful both in therapy and in ~.~or.;lo,ing the dosage ofthe inhibitors.
Por example, l~gelillg ligand which s~e~;r~rally reacts with a marker for the int~nded target tissue can be used. Mell~o~2c for co~p1:~ the il~f nlion CG~pvO~ t to the tal~,~,lil.g ligand are well known and are similar to those desc,ibvd below for cou~ g to carrier. The conj~ ,qtçs are forrm.lqted and administered as de3v~il,ed above.
Preparation and Use of Antibodies:
~ ntibo~iRc may be made by several n~etho~1c for f ~ the protein may be injected into suitable (e.g." ~ 9n) s~ cts itlCI~]t~ g m-ice~ rabbits, and the like.
P~ef~,..vd protocols involve repeated injection of the imn ~nooen in the p~3ellce of adjuvants according to a s~hed~lle which boosts produ~ioll of ~ bod;ec in the serum.
The titers of the immlm~ serum can readily be ..-cas~lr~d using immlmo~s~s~qy procedures, now standard in the art.
The antisera oblained can be used directly or n~Q~ clor~ql antibodies may be ob~t~ined by harvesting the pc~iphc.~l blood Iymphocytes or the spleen of the immllni7ed animal and imrnortali~ing the antil,oJ~-prodtlc;~ cells, fo"..,.ed by ide.ltil~;.lg the suitable antibody producers using ~ dal~d immllnosccvsy techni~ues.
Polyclonal or ~nnnoclonsl preparations are useful in ".or..lG.ù,g therapy or prophylaxis reg~ ,n~ involving the compounAC of the invention. Suitable samples such as those derived from blood, serurn, unne, or saliva can be tested for the pre~nce of the protein at various times during the ~ ,ç ~1 protocol using ~,Landard imml~nnsccs,y techniques which employ the antibody p~ &alions ofthe inv~ ion.
These antibodies can also be coupled to labels such as sc;nti~..phic labels, e.g., t~l~f-~iv ~ 99 or I-131, using standard coupling . ~ o~ The labeled compounds are ad~ tf-c~ to subjects to dete.-,lille the locvstiQ~c of excess a-novnts of one or more metalloprotea_es in vivo. Hence a labelled &.lil,ody to the protein would operate a a scr~ning tool for such ~h~nce~l eA~l~ss;on, ;l.~) c~ g the disease.
The ability of the antibodies to bind n~t~slloprolease selectively is thus talcen advantage of to map the distribution of these enymes in situ. The techniques can also be employed in histological procedures and the labeled -s-r~tibo~lies can be used in co"~p.,t;~i~e lmml~ C~ S.
Antibodies are advvntageol~sly c~rled to other compounds or materials using known methods. For example, materials having a carboxyl functionality, the carboxyl ~ residue can be reduced to an aldehyde and co~Fl~d to carrier through reaction with side chain amino groups, optionally followed by reducflon of imino linkage formed. The carboxyl residue can also be reacted with side chain amino groups using cQ~ e.~p.
agents such as dicyclohexyl carbodiimide or other carbodiimide dehydrating agents.
Linker compo~n~le can also be used to effect the coupling; both ho...ob-filnctional and h.,t~ .ob;r~ ;Q~ linkers are available from Pierce Chemical Company, Rockford, Iil.
These antibodies, when conjugated to a suitable chro..,alography material are useful in isolating the protein. Separation .~ o~ls using affinity cluol..alography are well known in the art, and are within the purview of the skilled artisan.
Disease marker Without being bound by theory, e.~.re~ ;cn of genes, and preferably this gene may have a restricted tissue distribution and its e.~ s;,;on is up regl~l?ted by potential osteoalllllil;s mediators. Fnh~l~Ge~ e.~yl~;on of this gene (and hence its protein) for e~_np'~ in articular chor.dlo.,ytes provides a marker to monitor the deve1~!pment ~ hl~1ine the earliest, as~ tG~Ilalic stages, and the pro~,s;.;on of osteoarthritis. Hence an antibody raised to the protein would operate a a s~;l-,c.-.n8 tool for such enhqnced e,~,ress;on, inA;~ cqti~ the disease.
In ad~1iti~n, when used in a disease screen, anlil,od;cs can be conju~ted to clu~nlophole or ~uorophole containing materials, or can be conjugated to er~...es which produce chro.-.opho- es or fluorophGres in certain con~litioll~ These conjngD-ti~

Example 4 [125Il d ~ ~ewi~ &l~il,od~ is pr~pared using IODOBEADS (Pierce, Rockford, IL;
immobilized chlo-,u-ane-T on ncsnpûrous pol~ e beads). LyophiliL~ antibody (2 ~g) is taken up in 50 Ill of 10 mM acetic acid and added to 450 ~l of phosphate-buffered saline (PBS) (Sigma, St. Louis, MO) on ice. To the tube is added 500 ~Curie Of ~25I
(A l.c.sh~n, Arlington ~Pight~ IL) (2200Ci/mmol) in 5 Ill, and one IODOBEAD. Thereaction is in~llb~ted on ice for l0 min with occ?~ionql shq~i~ The reaction is then te....; .~ed by remov. l ofthe re~~,tio~ from the IODOBEAD. To remove ul~e?~ed 125I, the mixture is applied to a PD-10 gel filtration ~D!--tnn Example 5 A fluorogenic peptide (~-hem Guelph Mills, King of Prussia, Pa) is mixed with the ~ egJ in and change in the fluorccence is evaluated at 2 min, as a control.. Then the ~uorogenic peptide is mixed with the ~;r:~ tr~in in the pl.,3ence ofthe compol~nd in ev~ qtior in a se~,a ale run, with evaluation at 2 mi~n~tes Data are evaluated using standald mPthodolc3y to provide relative binding ofthe evaluated CGI~.pO~nd F- r--ple 6 0.5ml of synovial fluid from the le~ knee of a patient is ~hithdla~l and tested for elevated levels dic:-~t~ n by ELISA. The results in~lic?te higher than normal .1;~ in level. The patient is ple..~..il~ed a prophylactic dose of a d;s;~ee,;n inhibitor, and is a~ ;s~ered an injection of same in the le~ knee before leaving the r~ ;ri~-'s office.
Example 7 Inhibition of eAlll,ce~ qr matrix ren~ode~ g is explored via inhibition of d:r~ e~ in metalloprotease activity. Using a small ~le~ qr weight, synthetic metalloprotease inhibitor, such as those used to inhibit the matrix metalloprot~ses, tissue ihllegrtly and pro~coglycsn is l..onilGled.
A sample of mouse derived articular cartilage is grown in a 1 miclo..lolar solution of a small ~ q~ weight d;~-.te~in inhibitor. The c.~pcl;n.e.~l is controlled andC~ U Cd to an identical culture grown with no inhibitor.
The assay of the culture after 7 days shows that the ;~-h-bj~ed culture has lesstissue breakdown and less ploteoglycan present in the serum of the culture. The result is cQr. ~ 1 with the inhibited agglcc~ ~e activity. Inhibition of a~giccanase would inhibit tissue breakdown and reduce the release of proteoglycan.
Example 8 Inhibition of proteolytic proceo~o;~ ~f --'I';~B in the release from the Illeml)l~e bound form of the ~io-integrin m~tq-lloprol~ domain inhibits "second .~.esse~
g ofthe .nen~ ne bound ~licinte~in m~'ewle. Such second ~PSs~pr~grr o~ignqlil~
would result in cellular phenotypic cl-~nges, ç~ es in gene e A~,res;,;on, rh~ges in mitotic activity, and the like.
Cells known to contain dio-inte~in are treated with a serine protease. Proteins released from the cell are meas.lred by s~ndard m~tho~s Speçific~lly the W O 97/31931 PCT~US97/03217 metalloprotease activity is Inon,lol c~ via literature m~thn~e. The amount of metalloprotease released is correlated to the amount of serine protease used to treat the cells Il,clcseses, versus control, in src tyrosine kinase activity a re measured by Western blot analysis of intracelh~l~qr proteins using mon~cl~nql anlil,odies specific for phosphotyrosine following cleavage and release of the dir; ~tegrin metalloprotea e. Controls are cells that have not been treated with serine protease.
src tyrosine kinase activity in the cell (or is it ceL culture) is measured by liler~lu,e me~q,thoAc Release ofthe meta!l~protease domain ofthe ~ lc~,n is also monitored via literature m~thoAc.. There is a direct co..~lalion b~ .~n release of the metalloprotease domain and illc~cases in intra.~ src tyrosine kinase activity This result is cor.~
with stimlllqtion of A ~ f~;n-...e l;~ted cell signaUing by c-timl~lqtion of the src tyrosine kinase cq~P~le.
E~amDle g Tnhi~ hiQn of ,nltlcdlular n~h~ n motec~ s~ or extracellular matrix co"~poncnls results in the inhibition of phenotypic cl~ B~ c, in~ ding ch~ge5 in cell shape, acsoçiq~ed with such interactions, as desc.;bed in Example 8.
Integrin binding is ...eas,lred with a peptide con~ g the sequen~e RGD, using the protocol of Example 8. Integrin binding is ...c~c~ ,d via com~,_t;l;~., assay, using cellular chq~g s in shape visible via ll,icl~scopy The peptide inhibits the ceUular ch~ s . s in Exarnple 8.
This result is CQ~C Ic ~I with c~.."~ ;on with or b'cc~ing of the interaction ofAicintegrin. The RGD peptide inhibits ceLular cl~ Bes in chondrwytes The osteoarthritis phe.~ot~e, characle.-Le~ by inc.~d matrix ~nlhe~.:s and acccle~lcd matrix metalloprotease activity does not occur. Other readily assayable cellular ch~r~eFs can be used to l..on-ter this result, incll~.1i~ gene .,,~p.es~;on, changes in mitotic activity, and the like.
Example 10 A small ~ r weight metallopr~,L~se inhibitor is used to treat a tissue culture accordu.~ to the method of Exarnple 7 The release of TNF{~ from the cellne is measured by literature metho-l$ The inhibitor of Example 7 also de~ s the ?~no~mt of TNF~ secreted from the cell membrane.
This is cQnCict~nt with the theory that inhibition of ~ 1e~;n metallop.o~ease activity will result in the inh:~ition of a .1i~ c~;n ~csoc~ted ;..n~ ...o-I;on ~ ç and W O 97/31931 PCTrUS97/03217 secretase activity. It is contemplated that monitoring the release of cytokines or IL-l from the cell l"~ I ane, and the like will produce the same result.
re~ences described herein are hereby incol},ola~ed by It;rerence.
While particular embod; ..~ s of the subject invention have been des_lil.ed, it will be obvious to those skilled in the art that various c~ ges and mo~lifi~tionc of the subject invention can be made without departing from the spirit and scope of the invention.

As used herein, the terms "protein," "protease," and "metalloprotease" refer to a ~licintegrin. ~lerelably this is a human riicinte~in as desc.il,ed below.
The term "antibody" refers to an ~llibody to a rliQ;'te~in, or fragment thereo~
These many be molloclonql or polyclonal, . nd can be from any of several . ources. The invention also co~m .~pl~c5 L~ e.-l~ of these antibodies made by any method in the protein or peptide art.
The term "disease screen" refers to a screen for a disease or disease state. A
disease state is the physiole~r-s-l or cellular or b:cchenlical ..-9 .;~ ~,t~l;on of the disease.
îc~bly this screen is used on body tissues or fluids of an animal or cell culture, using ~and~d techniques, such as ELISA. It also Co~ 9~'eS "~"~pp- ~g~ of disease in a whole body, such as by labeled antibody as desc,il,ed above given ~ r~lly regardless of the detectio~ m.otho-l, preferable such detectio~ .od~ include fluoi~s~encç, X-ray (inchl~li~ CAT scan), N~ (Tnr~ li~ MRI), and the like.
The term "cGl"po~md screen" is related to the ...~.lho~ls and screens related tofinding compounds, determining their affinity for the protease, or decigr.i~ or se~e~ g co"l~)ollnds based on the screen. In another Pmho~ nt~ it co.~- .pl~es the use of the three dimensional structure for drug design, preferable "rational drug design", as undc.~lood by the art. It may be pl~.f~ cd that the prote~ is in "es~ ly pure form", which refers to a protein re--o~-~ly free of other impulilics, so as to make it useful for cA~e~im~ls or chara~ ion. Use of this sel~,ning method assists the skilled artisan in finding novel structures, whether made by the chemist or by nature, which bind to and preferably inhibit the protease. These "inhibitors" may be useful in re~Jl~tin~ or moch ting the activity of the protcase, and may be used to thus mod~ te the b-olo~
cascade that they fi-nctiQn in. This appl.a-h affords new pha, - eutiçslly useful compounds.
The term "disinte~in" refers to a diQ;nte~g~in, a fragment thereof, a mutant thereof or a homnl~-e which still retains its fi~nCtio~ This term conlen~ es aggrn-qr~qse, and other p~ot~s which are involved in or modul~e tissue r~mr)dellin~ This conte-..p!~es ~iQ~ .If~ins from di~cling, species, and those prepar. d by recol.lbinanl m~thodc, in vitro m~thod5, or ~landald peptide ~l~thes;s. Preferably the protein is a human dic; ~leg~in or mutant thereof. For the purposes of ~fini~ the mut~ntQ~ of the protein the p~cÇcl~,d W O 97/31931 PCT~US97/03217 "native" protein is described in t~nR~ accession # Z48579, inco.~lo.~led herein by r~;rer~. ce and le~.red to in the seqllPnce below. SEQ ID NO 1 de,s~ es a fragment of that DNA sequence and its transcript and SEQ ID NO 2 describes the coding region of the gene and its l-~ns~,-ipt. Homologue d;C n~ ;nS include whole proteins with at least 90% homology as unde.~lood by the art, Ot ~iAgJ~ r~S thereo~ For exarnple, a ratprotein which is 95% homologous to that of SEQ ID NO. I or SEQ ID NO. 2 based onthe peptide sequence derived from the DNA or cDNA se~Upnce~ and a bovine protein~5i.,~il&,1y derived) being 97-98% homologous, are both conQ;de~ed homologuPs Thus homologous cDNAs cloned from other o~ n~ s give rise to homologous proteins.
Likewise pr~te.ns may be co-- de~ed homolcel~es based on the amino acid sequenre alone. Practical lin.;~ ;ol-~ of amino acid seq~lencing would allow one to d.,tel.-une that a protein is homologous to another using for ~ rle Co~l~yaliSOn of the first 50 amino acids ofthe protein. Hence 90% l~nlol~gy in would allow for 5 di~,.ing an~ino acids in the chain of the first 50 amino acids of the hon~f ~OgO~lS protein.
The skilled artisan will al,p,~,~,;ate that the de&_ne~_ ~ of the genetic code provides for dilrt;ling DNA sequences to provide the same l.ans_~ipt, and thus the sarne peptide. In certain cases pr~_paring the DNA seq~eneç, which encodes for the same peptide, but differs from the native DNA include;
~- ease of seq~pn~;ng or synthesis;
--- ine,~sed e,.prejiion of the peptide; and .,f~,rence of certain heterologous hosts for certain codons over others.
These practical conQ;~Ierations are widely kno~,vn and provide elllbo-J; ~.. nls that may be adv~ ~t~eQus to the user of the invention. Thus it is clearly cont~Q"..p~ ed that the native DNA is not the only ~--, bod:- n~ envisioned in this invention.
In r ~itiQn it is ap~e,.lt to the skilled artisan that L~ ne .-l c of the protein may be used in screening, drug design and the like, and that the entire peptide may not be r~uir~ for the ~ oses of using the invention. Thus it is clearly conte..~ ted that the skilled artisan will unde-~L~nd that the ~icrlosvre ofthe peptide and its uses contemplates the useful peptide fr~ ntc The practical consid~,lalions of protein c.~l)re~.;on, purification yield, stability, solLhility, and the like, are cor~;dç~ed by the skilled artisan when choo~;l.g ~~fLelher to use a ~ 1 and the fi~"l~ to be used. As a result, using routine practices in the art, the artisan can, given this disclosure p. ~.c~ice the invention using rl ag...~ ~1 s of the protein as well.
s The protein or pro~ease itself can be used to determine the binding activity of small ms~le~ules to the protein. Drug scle.,.~il 8 using enymatic targets is used in the art and can be employed using all~o...aled, high throughput technologies.
The inh;bition of dicinte~in activity may be a predictor of efficacy in the l-c~n.~-~of oste-oa-llu;lis, and other d ~ ACe~: involving dege~c~alion of articular cartilage.
Gene therapy Without being bound by theory it is thought that the metalloprotease is up regulvsted during osteoarthritis in tissues. We have SII~ u~gly found that a human ~lisintegrin is up-re~ ed in human chond.o~,~rtes during o~leoa.lluilic conAitionc Inhibition of signal trncd~ctiQn ...ech~ .. is cn.c~cio -c in dis.u~)th~g the rqccade of events in osteo~lluilis and other A;cç~c~s involving ca.lilage degene.alion. The skilled artisan will ~cco~uLe that if up-re~llAtion is a cause of the onset of arthritis, then interfering with the activity ofthis gene may be useful in treating oslfJoa-lluilis.
This is done by any of several ~ hod~ inclu~ii~ gene (i.e., A~-1 ;~n.~) therapy.Inhibitors of the f~ f ~y ;n The plo~ease of the invention can be used to find inhibitors of the prot~.
Hence it is useful as a scree~ng tool or for rational drug design. Without being bound by theory, the protease may modulate cellular rc.n~ g and in fact may enhsnce extracellular matrix ren od~ling and thus e-~h~r~ee tissue breakdo vn.. Hence inhib;tion of tegrin provides a ~ peulic route for ll~ nl of diC~F,5 chara.,lcliLcd by these ~. ~c~ss~,s In sc.-,~fing, a drug compound can be used to dct.,...une both the quality and quantity of inhibition. As a result such scr~lullg provides i~lfu~ alion for selection of actives, preferably smaD c'~cule actives, which are useful in ~l~,aling these diseases.
In therapy, inh:bifion of ~ 1c~yin me~s~cp~ulease activity via binding of small sr weight, ~.l~h~,lic metalloplote~e inhibitors, such as those used to inhibit the matrLx m_taUoproteases would be used to inhibit ~"~ll r~ ls~ matrix remodPIing L~libodies to the protein Metalloprûl~s active at a puticululy undesired loc~ion (e.g., an orgul or certain types of cells) can be lalg~led by ~ u l, g,gti~ a metallop, .,l~sc inhibitor to a to an untibody or fragment thereo~ Conj--8,s-tion rnetho-lc ue known in the art.
The a.l~il,od~ of the invention CUI also be conjugated to solid s.~ )G.ls. TheseconJIlgates can be used as affinity ,~,ag~ s for the purifi~iQn of a desired metalloprotease, preferably a ~ e~,u~.
, In another aspect, the antibody of the invention is directly conjugs-ted to a label.
As the antibody binds to the metallop~oteas_, the label can be used to detect the p~sence of relatively high levels of metalloploteast in vivo or in vitro cell culture.
In addition, the metallopro~ease inhibiting conlroun~s can be cor~ ated to antibodies. Typical conjugation metho~c are known in the art. These antibodies are then useful both in therapy and in ~.~or.;lo,ing the dosage ofthe inhibitors.
Por example, l~gelillg ligand which s~e~;r~rally reacts with a marker for the int~nded target tissue can be used. Mell~o~2c for co~p1:~ the il~f nlion CG~pvO~ t to the tal~,~,lil.g ligand are well known and are similar to those desc,ibvd below for cou~ g to carrier. The conj~ ,qtçs are forrm.lqted and administered as de3v~il,ed above.
Preparation and Use of Antibodies:
~ ntibo~iRc may be made by several n~etho~1c for f ~ the protein may be injected into suitable (e.g." ~ 9n) s~ cts itlCI~]t~ g m-ice~ rabbits, and the like.
P~ef~,..vd protocols involve repeated injection of the imn ~nooen in the p~3ellce of adjuvants according to a s~hed~lle which boosts produ~ioll of ~ bod;ec in the serum.
The titers of the immlm~ serum can readily be ..-cas~lr~d using immlmo~s~s~qy procedures, now standard in the art.
The antisera oblained can be used directly or n~Q~ clor~ql antibodies may be ob~t~ined by harvesting the pc~iphc.~l blood Iymphocytes or the spleen of the immllni7ed animal and imrnortali~ing the antil,oJ~-prodtlc;~ cells, fo"..,.ed by ide.ltil~;.lg the suitable antibody producers using ~ dal~d immllnosccvsy techni~ues.
Polyclonal or ~nnnoclonsl preparations are useful in ".or..lG.ù,g therapy or prophylaxis reg~ ,n~ involving the compounAC of the invention. Suitable samples such as those derived from blood, serurn, unne, or saliva can be tested for the pre~nce of the protein at various times during the ~ ,ç ~1 protocol using ~,Landard imml~nnsccs,y techniques which employ the antibody p~ &alions ofthe inv~ ion.
These antibodies can also be coupled to labels such as sc;nti~..phic labels, e.g., t~l~f-~iv ~ 99 or I-131, using standard coupling . ~ o~ The labeled compounds are ad~ tf-c~ to subjects to dete.-,lille the locvstiQ~c of excess a-novnts of one or more metalloprotea_es in vivo. Hence a labelled &.lil,ody to the protein would operate a a scr~ning tool for such ~h~nce~l eA~l~ss;on, ;l.~) c~ g the disease.
The ability of the antibodies to bind n~t~slloprolease selectively is thus talcen advantage of to map the distribution of these enymes in situ. The techniques can also be employed in histological procedures and the labeled -s-r~tibo~lies can be used in co"~p.,t;~i~e lmml~ C~ S.
Antibodies are advvntageol~sly c~rled to other compounds or materials using known methods. For example, materials having a carboxyl functionality, the carboxyl ~ residue can be reduced to an aldehyde and co~Fl~d to carrier through reaction with side chain amino groups, optionally followed by reducflon of imino linkage formed. The carboxyl residue can also be reacted with side chain amino groups using cQ~ e.~p.
agents such as dicyclohexyl carbodiimide or other carbodiimide dehydrating agents.
Linker compo~n~le can also be used to effect the coupling; both ho...ob-filnctional and h.,t~ .ob;r~ ;Q~ linkers are available from Pierce Chemical Company, Rockford, Iil.
These antibodies, when conjugated to a suitable chro..,alography material are useful in isolating the protein. Separation .~ o~ls using affinity cluol..alography are well known in the art, and are within the purview of the skilled artisan.
Disease marker Without being bound by theory, e.~.re~ ;cn of genes, and preferably this gene may have a restricted tissue distribution and its e.~ s;,;on is up regl~l?ted by potential osteoalllllil;s mediators. Fnh~l~Ge~ e.~yl~;on of this gene (and hence its protein) for e~_np'~ in articular chor.dlo.,ytes provides a marker to monitor the deve1~!pment ~ hl~1ine the earliest, as~ tG~Ilalic stages, and the pro~,s;.;on of osteoarthritis. Hence an antibody raised to the protein would operate a a s~;l-,c.-.n8 tool for such enhqnced e,~,ress;on, inA;~ cqti~ the disease.
In ad~1iti~n, when used in a disease screen, anlil,od;cs can be conju~ted to clu~nlophole or ~uorophole containing materials, or can be conjugated to er~...es which produce chro.-.opho- es or fluorophGres in certain con~litioll~ These conjngD-ti~
materials and m~tho~s are well known in the art. When used in this manner detection of the protein by immlll~nqr~-~ is ;.l~ htr lward to the skilled artisan. Body fluids, for example can be scr~ned in this manner for calibration, and d~,t~l;ol of distribution of metallopr~ Q~-~, or i..~ ased levels ofthese prot~D~Q
When used in this way the inv~nlion is a useful diagnostic and/or clinical marker for met~'lopr~te~e mediated f~ eP5~ such as osteoarthritis or other articular cartilage de~,ene~ali./e ~ ~D~S When disease is detecte~l it may be treated before the onset of syrnptom or debilit~tion Fu.lhe.ll.ore, such antibodies can be used to target di-~~ e~ tissue, for dete~,l;on or 11.~ It as desclibed above.

Example 4 [125Il d ~ ~ewi~ &l~il,od~ is pr~pared using IODOBEADS (Pierce, Rockford, IL;
immobilized chlo-,u-ane-T on ncsnpûrous pol~ e beads). LyophiliL~ antibody (2 ~g) is taken up in 50 Ill of 10 mM acetic acid and added to 450 ~l of phosphate-buffered saline (PBS) (Sigma, St. Louis, MO) on ice. To the tube is added 500 ~Curie Of ~25I
(A l.c.sh~n, Arlington ~Pight~ IL) (2200Ci/mmol) in 5 Ill, and one IODOBEAD. Thereaction is in~llb~ted on ice for l0 min with occ?~ionql shq~i~ The reaction is then te....; .~ed by remov. l ofthe re~~,tio~ from the IODOBEAD. To remove ul~e?~ed 125I, the mixture is applied to a PD-10 gel filtration ~D!--tnn Example 5 A fluorogenic peptide (~-hem Guelph Mills, King of Prussia, Pa) is mixed with the ~ egJ in and change in the fluorccence is evaluated at 2 min, as a control.. Then the ~uorogenic peptide is mixed with the ~;r:~ tr~in in the pl.,3ence ofthe compol~nd in ev~ qtior in a se~,a ale run, with evaluation at 2 mi~n~tes Data are evaluated using standald mPthodolc3y to provide relative binding ofthe evaluated CGI~.pO~nd F- r--ple 6 0.5ml of synovial fluid from the le~ knee of a patient is ~hithdla~l and tested for elevated levels dic:-~t~ n by ELISA. The results in~lic?te higher than normal .1;~ in level. The patient is ple..~..il~ed a prophylactic dose of a d;s;~ee,;n inhibitor, and is a~ ;s~ered an injection of same in the le~ knee before leaving the r~ ;ri~-'s office.
Example 7 Inhibition of eAlll,ce~ qr matrix ren~ode~ g is explored via inhibition of d:r~ e~ in metalloprotease activity. Using a small ~le~ qr weight, synthetic metalloprotease inhibitor, such as those used to inhibit the matrix metalloprot~ses, tissue ihllegrtly and pro~coglycsn is l..onilGled.
A sample of mouse derived articular cartilage is grown in a 1 miclo..lolar solution of a small ~ q~ weight d;~-.te~in inhibitor. The c.~pcl;n.e.~l is controlled andC~ U Cd to an identical culture grown with no inhibitor.
The assay of the culture after 7 days shows that the ;~-h-bj~ed culture has lesstissue breakdown and less ploteoglycan present in the serum of the culture. The result is cQr. ~ 1 with the inhibited agglcc~ ~e activity. Inhibition of a~giccanase would inhibit tissue breakdown and reduce the release of proteoglycan.
Example 8 Inhibition of proteolytic proceo~o;~ ~f --'I';~B in the release from the Illeml)l~e bound form of the ~io-integrin m~tq-lloprol~ domain inhibits "second .~.esse~
g ofthe .nen~ ne bound ~licinte~in m~'ewle. Such second ~PSs~pr~grr o~ignqlil~
would result in cellular phenotypic cl-~nges, ç~ es in gene e A~,res;,;on, rh~ges in mitotic activity, and the like.
Cells known to contain dio-inte~in are treated with a serine protease. Proteins released from the cell are meas.lred by s~ndard m~tho~s Speçific~lly the W O 97/31931 PCT~US97/03217 metalloprotease activity is Inon,lol c~ via literature m~thn~e. The amount of metalloprotease released is correlated to the amount of serine protease used to treat the cells Il,clcseses, versus control, in src tyrosine kinase activity a re measured by Western blot analysis of intracelh~l~qr proteins using mon~cl~nql anlil,odies specific for phosphotyrosine following cleavage and release of the dir; ~tegrin metalloprotea e. Controls are cells that have not been treated with serine protease.
src tyrosine kinase activity in the cell (or is it ceL culture) is measured by liler~lu,e me~q,thoAc Release ofthe meta!l~protease domain ofthe ~ lc~,n is also monitored via literature m~thoAc.. There is a direct co..~lalion b~ .~n release of the metalloprotease domain and illc~cases in intra.~ src tyrosine kinase activity This result is cor.~
with stimlllqtion of A ~ f~;n-...e l;~ted cell signaUing by c-timl~lqtion of the src tyrosine kinase cq~P~le.
E~amDle g Tnhi~ hiQn of ,nltlcdlular n~h~ n motec~ s~ or extracellular matrix co"~poncnls results in the inhibition of phenotypic cl~ B~ c, in~ ding ch~ge5 in cell shape, acsoçiq~ed with such interactions, as desc.;bed in Example 8.
Integrin binding is ...eas,lred with a peptide con~ g the sequen~e RGD, using the protocol of Example 8. Integrin binding is ...c~c~ ,d via com~,_t;l;~., assay, using cellular chq~g s in shape visible via ll,icl~scopy The peptide inhibits the ceUular ch~ s . s in Exarnple 8.
This result is CQ~C Ic ~I with c~.."~ ;on with or b'cc~ing of the interaction ofAicintegrin. The RGD peptide inhibits ceLular cl~ Bes in chondrwytes The osteoarthritis phe.~ot~e, characle.-Le~ by inc.~d matrix ~nlhe~.:s and acccle~lcd matrix metalloprotease activity does not occur. Other readily assayable cellular ch~r~eFs can be used to l..on-ter this result, incll~.1i~ gene .,,~p.es~;on, changes in mitotic activity, and the like.
Example 10 A small ~ r weight metallopr~,L~se inhibitor is used to treat a tissue culture accordu.~ to the method of Exarnple 7 The release of TNF{~ from the cellne is measured by literature metho-l$ The inhibitor of Example 7 also de~ s the ?~no~mt of TNF~ secreted from the cell membrane.
This is cQnCict~nt with the theory that inhibition of ~ 1e~;n metallop.o~ease activity will result in the inh:~ition of a .1i~ c~;n ~csoc~ted ;..n~ ...o-I;on ~ ç and W O 97/31931 PCTrUS97/03217 secretase activity. It is contemplated that monitoring the release of cytokines or IL-l from the cell l"~ I ane, and the like will produce the same result.
re~ences described herein are hereby incol},ola~ed by It;rerence.
While particular embod; ..~ s of the subject invention have been des_lil.ed, it will be obvious to those skilled in the art that various c~ ges and mo~lifi~tionc of the subject invention can be made without departing from the spirit and scope of the invention. It is intended to cover, in the appended claims, all such m~ fi~q~iorl~ that are vithin the scope of this invention.
