Cytokine receptor

FIELD OF THE INVENTION

The present invention relates generally to structural studies of the interleukin-6 (IL-6) receptor. More particularly, the present invention relates to the crystal structure of the IL-6 receptor α chain (IL-6R). Even more particularly, the instant invention relates to the crystal structure of an extracellular portion of IL-6R and to methods of using the crystal and related structural information to screen for and design compounds that interact with IL-6R, or variants of thereof.

BACKGROUND OF THE INVENTION

Interleukin-6 (IL-6) is a multifunctional cytokine that plays a central role in host defense due to its wide range of immune and haematopoietic activities and its potent ability to induce acute phase response (for review see Simpson et al. 1997, Protein Sci 6, 929-55). It appears to represent an important frontline component of the body's armory against infection or tissue damage (IL-6 knockout mice have impaired immune and acute phase responses. IL-6 was originally referred to by such diverse names as interferon-β2, 26K factor, B-cell stimulating factor 2, hybridoma growth factor, plasmacytoma growth factor, hepatocyte-stimulatory factor, a haematopoietic factor and cytotoxic T-cell differentiation factor—each name reflecting a different biological activity controlled by the same protein. Over the last ten years it has become clear that the functional pleiotropy of Interleukin-6 has implicated this cytokine in the pathology of many human diseases such as multiple myeloma, rheumatoid arthritis, Castleman's disease, AIDS, mesangial proliferative glomerulonephritis, Kaposi's sarcoma, sepsis, osteoporosis and psoriasis. Given the association of abnormal IL-6 production and clinical disorders there is great interest in the development of functional agonists and antagonists as potential therapeutic agents in the treatment of IL-6 associated diseases.

The biological activities of IL-6 are mediated by the IL-6 receptor complex, which consists of two membrane proteins, the ligand binding α-chain receptor (IL-6R, gp80) and the signal transducing β-chain, gp130, which also forms part of the receptor complexes of LIF, OSM, CNTF, IL-11 as well as CT-1. Co-expression of IL-6R and gp130 results in both low- and high-affinity binding sites for IL-6, the relative amounts of the two chains dictating the ratio between the two affinity states. High affinity binding is likely due to the ability of IL-6 to interact simultaneously with sites on the IL6-R and gp130. Typically the difference in affinity between low- and high-affinity binding is ˜100-fold; e.g., on human myeloma U266 cells, IL-6 first binds IL-6R with an affinity of ˜1 nM, and the IL-6/IL-6R complex then binds gp130 with a resulting affinity of ˜10 pM. Binding of IL-6 has been demonstrated on a variety of human cells. Although human IL-6R shows broad distribution (e.g., activated B-cells, resting T-cells, B lymphoblastoid cell types, hepatoma lines, myeloma and monocyte cell lines), some cells lack this type of receptor. Normal cells express between 10²and 10³receptors, while human myeloma U266 and EB virus-transformed CESS cells have up to 10⁴receptors.

The cDNA of the human IL-6R encodes a protein of 468 amino acids, including a signal peptide of 19 amino acids, an extracellular region of 339 amino acids, a transmembrane domain of 28 amino acids, and a short cytoplasmic domain of 82 amino acids (Yamasaki et al., 1988, Science 241: 825-828). There are six potential N-linked glycosylation sites on the extracellular domain, the mature 80 kDa IL-6R is a glycosylated form of the predicted 50 kDa precursor. Secondary structural predictions indicate that the extracellular region is highly modular, consisting of three domains (D1, D2 and D3) of approximately 100 residues. These domains consist of an N-terminal domain D1 characteristic of the immunoglobulin (Ig) superfamily and a cytokine binding domain (CBD), which consists of two fibronectin type III-like (FN III) domains (a subclass of the Ig-fold). The CBD of IL-6R is characteristic of the class I cytokine receptors. In common with other members of this receptor family, the N-terminal FIII domain (D2) of the CBD has four conserved cysteines, while the C-terminus FIII domain (D3) has a conserved sequence motif, the “WSXWS” motif. The Ig domain D1 has been deleted without major effect on the binding of IL-6 or signal transduction, suggesting that the CBD mediates binding to IL-6 and gp130. The transmembrane and cytoplasmic domains of the IL-6R are not necessary for signal transduction, as shown by the fact that the complex of IL-6 and extracellular “soluble” domain of IL-6R induces signal transduction on cells expressing gp130.

Notwithstanding the known biology of the IL-6R complex, the design of IL-6R complex agonists or antagonists is impeded greatly by the lack of three-dimensional structural information available for this complex. Accordingly, knowledge of the three-dimensional structure coordinates of the IL-6R complex would be useful in facilitating the design of potential selective agonists/antagonists which, in turn, are expected to have therapeutic utility.

The term “molecular replacement” refers to a method that involves generating a preliminary model of an IL-6 extracellular domain crystal whose structure coordinates are unknown, by orienting and positioning a molecule whose structure coordinates are known (e.g., IL-6 receptor extracellular coordinates from Appendix I) within the unit cell of the unknown crystal so as best to account for the observed diffraction pattern of the unknown crystal. Phases can then be calculated from this model and combined with the observed amplitudes to give an approximate Fourier synthesis of the structure whose coordinates are unknown. This, in turn, can be subject to any of the several forms of refinement to provide a final, accurate structure of the unknown crystal (Lattman, 1985, Methods in Enzymology 115: 55-77; M. G. Rossmann, ed., “The Molecular Replacement Method”, Int. Sci. Rev. Ser., No. 13, Gordon & Breach, New York, 1972).

Throughout this specification, the word “comprise”, or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, integer or step, or group of elements, integers or steps.

DETAILED DESCRIPTION

The present inventors have determined the three-dimensional structure of the extracellular region of the IL-6R. The X-ray structure of IL-6R reveals a structure consisting of the N-terminal Ig domain (D1) linked to a classical CBD (D2, D3). The first 5 residues of the N-terminus are poorly defined and amino acids past residue 299 are not visible in the X-ray structure. The D2 and D3 are connected at about 90° to each other and D1 is connected at about 45° to D2. The three domains lie on a similar plane making the receptor a long ‘flat’ structure. Carbohydrate is observed at 4 sites (five hexoses on the Asn226 site), all only on one of the ‘flat’ faces of the molecule, indicating that this face would have very restricted involvement in the signalling complex. This is consistent with evidence of expression of functional sIL-6R in Escherichia coli. The N-terminus Cys6 is disulphide bonded to Cys174 in D2, and this anchoring results in an unusual β-sheet arrangement of D1. D1 has an s-type Ig topology (0.7 Å rmsd with the ligand binding domain of fibroblast growth factor (Stauber et al., 2000, PNAS 97: 49-54), but the first ‘a’ strand of the 3-stranded β-sheet has moved to form a fifth ‘h’ strand of the 4-stranded β-sheet. This could be a result of crystal packing and represent a degree of flexibility of this domain, acting as a conformational switch, allowing D1 to rotate about 20° by β-strand shifting. This could also explain the higher disorder in this domain resulting in lack of isomorphism between different crystals of IL-6R. As in other cytokine FnIII domains, the domains are separated by a double proline motif (Pro94-Pro95, Pro199-Pro200 and Pro302-Pro303 at the end of D1, D2 and D3 respectively).

The other characteristic of the CBD of IL-6R is the long tryptophane-arginine ladder (from the C-terminus end of D3 is Arg239, Phe246, Arg237, Trp287, Arg274, Trp284, Gln276) found in other class 1 CBD structures (Carr et al., 2001). This ladder incorporates the conserved WSXWS motif (Residues 284 to 287 in IL-6R) located in the COOH-terminal of CBDs. The polypeptide backbone of this motif has an unusual left-handed 3₁₀helix similar to a poly-proline helix, stabilised by the large tryptophane and arginine stacking and not by main chain H-bonds. This results in a long surface stripe of positive charge (from the guanidinium and tryptophane nitrogens) running along the side of the inside elbow portion of D3, and a groove formed by the 3₁₀helix running parallel to it. The function of this structure is unknown, but the similarities with other CBDs would suggest that it could be involved in a general receptor transport system and not in IL-6 binding.

Following the fibroblast growth factor paradigm (Stauber et al., 2000), it would be expected that IL-6 would bind in the region of the outer elbow formed at the junction of D2 and D3, characterised by 4 loops (L1 to L4) from D2 and 3 loops (L5 to L7) from D3. IL-6 would engage residues in these loops, and mutation in these residues would affect IL-6 binding. Mutational analyses indicate that most of the mutations, when mapped onto the crystal structure, have altered binding due to alterations in the structural integrity of the molecule, in particular mutations in the tryptophane/arginine ladder. Discarding these ‘structural’ mutations, there are clusters of mutations in loops L3, L5 and L7 that reduce binding to IL-6. This site is at the juncture of D2 and D3 domains, and can be inferred to be primarily responsible for IL-6 binding.

In the crystal lattice two molecules of IL-6R related by a crystallographic 2-fold axis are closely associated along the length of each molecule. The association is primarily a hydrophobic contact around the 2-fold axis involving Phe134 and Phe168 of domain D2, the salt-link Glu97-Arg274, and H-bonding of Glu283 with the main chain nitrogens of Thr186. The buried accessible surface area of each molecule is about 1230 Å²(shape and electrostatic complementarity of 0.722 and 0.728), and is what could be expected for a protein-protein interaction in solution. Furthermore the buried surface of a protein complex does not have to be as extensive for membrane bound receptors to interact, compared to complexes formed where one or both components are in solution. So it is consistent with IL6-R forming dimers on the cell surface of the type observed in the crystal.

The orientation of the dimer is such that the interaction is along the carbohydrate-free ‘flat’ face of the molecule. In this model, domain D3 comes up away from the membrane at 45° and D2 comes down towards the membrane at 30°, with finally D1 running parallel to the membrane. The dimer thus appears as a bridge structure like the common β-receptor of IL-3, with a 50 Å tunnel of triangular cross-section (base ˜40 Å; height ˜22 Å). Non-structural mutations in IL-6R that affect gp130 signalling are found on the loops L1, L3, L5 and L6, and also in a patch of residues at the dimer interface consisting of residues 140 to 142, 167 to 171 (reduce signalling (and 182 to 186 (increase signalling) of the N-terminal side of the d, f and g strands of D2 respectively. These is also mutations in a patch of residues (209 to 213 and 261 to 263) on the membrane distal side of domain D2 that reduce binding.

The recent structure of the Ig and CBD domain gp130 and viral IL-6 complex (Chow et al., 2001, Science 291: 2150-5) reveals a possible dimeric relationship between the IL-6 binding domains of gp130. Thus incorporating the dimeric relationship between all the IL-6 binding receptor domains it is possible to construct a model for the signalling complex that is substantially different from current proposed models and consistent with the available mutational data. Here two IL-6 molecules bind to the IL-6R dimer, followed by two gp130 each binding to both IL-6 molecules in a similar way to the viral IL-6/gp130 fragment complex. gp130 would bind with its second CBD pointing away from the membrane. The remaining three FnIII domains of gp130 would head down towards the membrane, and the signalling activated by dimerisation of the membrane proximal FnIII domains under the bridge of the IL-6R dimer likely through disulphide crosslinking.

Clearly the information provided in this application will enable rational design/selection of compounds which will interact with IL-6R.

Accordingly, in a first aspect the present invention provides a method of selecting or designing a compound that interacts with an IL-6 receptor and modulates an activity mediated by the receptor, the method comprising

(a) assessing the stereochemical complementarity between a compound and a topographic region of the receptor, wherein the receptor comprises:

- (i) amino acids 1-299 of the IL-6 receptor positioned at atomic coordinates as shown in Appendix I, or structural coordinates having a root mean square deviation from the backbone atoms of said amino acids of not more than 1.5 Å; or
- (ii) one or more subsets of said amino acids related to the coordinates shown in Appendix I by whole body translations and/or rotations;

(b) obtaining a compound which possesses stereochemical complementarity to a topographic region of the receptor; and

In a preferred embodiment of the first aspect, the subset of amino acids is selected from the group consisting of the subset of amino acids representing the D1 domain (residues 1 to 93), the subset of amino acids representing the D2 domain (residues 94 to 194) and the subset of amino acids representing the D3 domain (residues 195 to 299).

As discussed above, following the fibroblast growth factor receptor paradigm it is expected that IL-6 will bind to IL-6R in the region of the outer elbow formed at the junction of D2 and D3, characterised by 4 loops (L1 to L4) from D2 and 3 loops (L5 to L7) from D3. The ligand binding surfaces of IL-6R are therefore defined by residues 106-110, 133-138, 160-168, 190-193, 227-233, 250-256 and 276-281.

Accordingly, in a preferred embodiment the compound is selected or designed to interact with the IL-6 receptor in a manner such as to interfere with the binding of natural ligand to one or more of the residues of IL-6R selected from the group consisting of 106-110, 133-138, 160-168, 190-193, 227-233, 250-256, 276-281 and combinations thereof.

The present inventors have determined that the IL-6R homodimer involves interaction along the carbohydrate free flat faces of the two IL-6 receptors. This dimer interface is defined by residues 1-5, 19-23, 65-69, 93-99, 118, 119, 132-141, 166-172, 179-196, 241-250, 261, 262, 272-276 and 282-290.

Accordingly, in a preferred embodiment the compound is selected or designed to interact with the IL-6 receptor in a manner such as to interfere with IL-6R homodimer formation.

The compound may interfere with ligand binding or dimer formation in a number of ways. For example the compound may bind or interact with the receptor at or near one or more of the specified residues or corresponding regions and by steric overlap and/or electrostatic repulsion prevent natural ligand binding or dimer formation. Alternatively the compound may bind to the receptor so as to interfere allosterically with natural ligand binding or dimer or formation.

It is presently preferred, however, that the compound binds or interacts with the receptor at or near one or more of the specified residues.

The present inventors have also identified two other regions of the IL-6 receptor that are of particular interest in the development of compounds which affect IL-6 receptor activity. The first is an apparent allosteric switch in D1. It was observed that the first ‘a’ strand of the 3-stranded β-sheet of D1 has moved to form a fifth ‘h’ strand of the 4-stranded β-sheet. This could be a result of crystal packing and represent a degree of flexibility of this domain, acting as a conformational switch, allowing D1 to rotate about 20° by b-strand shifting. This proposed allosteric movement can be blocked by designing a molecule to bind to this switch region and block the putative movement. This region is defined by the residues 11, 45, 46, 55, 62-66, 69-72, 75, 81, 88, 90-93, 122-124 and 178.

The second is the long tryptophane-arginine ladder which incorporates the conserved WSXWS motif. The polypeptide backbone of this motif has an unusual left-handed 3₁₀helix similar to a poly-proline helix, stabilised by the large tryptophane and arginine stacking and not by main chain H-bonds. This results in a long surface stripe of positive charge (from the guanidinium and tryptophane nitrogens) running along the side of the inside elbow portion of D3, and a groove formed by the 3/10 helix running parallel to it. The function of this structure is unknown, but the similarities with other CBDs would suggest that it could be involved in a general receptor transport system and not in IL-6 binding. Blocking this region could be useful to regulate transport of receptor to the cell surface. This region is defined by the following residues 233-239, 244-248 and 270-290. The WSXWS motif is residues 284-287.

Accordingly in a preferred embodiment of the first aspect of the present invention, the method comprises selecting or designing a compound which has portions that match residues positioned on;

- (i) the ligand binding surface of IL-6R defined by amino acids 106-110, 133-138, 160-168, 190-193, 227-233, 250-256 and 276-281; or
- (ii) the IL-6R dimer interface defined by amino acids 1-5, 19-23, 65-69, 93-99, 118, 119, 132-141, 166-172, 179-196, 241-250, 261, 262, 272-276 and 282-290; or
- (iii) amino acids 11, 45, 46, 55, 62-66, 69-72, 75, 81, 88, 90-93, 122-124 and 178 of IL-6R; or
- (iv) amino acids residues 233-239, 244-248 and 270-290 of IL-6R.

By “match” we mean that the identified portions interact with the surface residues, for example, via hydrogen bonding or by enthalpy-reducing Van der Waals interactions which promote desolvation of the biologically active compound with the receptor, in such a way that retention of the compound by the receptor is favoured energetically.

In a further preferred embodiment of the present invention, the stereochemical complementarity is such that the compound has a K_dfor the receptor site of less than 10⁻⁶M. More preferably, the K_dvalue is less than 10⁻⁸M and more preferably less than 10⁻⁹M.

In preferred embodiments of the first aspect of the present invention, the compound is selected or modified from a known compound identified from a data base.

For example this specification provides information regarding the portions of IL-6 which are involved in receptor binding. With this information IL-6 variants may be designed in which specific residues are modified or altered such that the variant is able to bind to the receptor but not initiate signalling. It would be expected that such a variant would compete with the natural ligand for binding to the receptor. Such a variant would therefore be an antagonist. In a similar manner variants which would act as agonists could be designed. In this case the modifications or alterations would be selected such as to increase the strength of interaction between the receptor and the variant so as to lead to increased signalling.

As will be understood by those skilled in this field knowledge of the structure of a protein complex is of assistance in the development of mutants of one of the proteins with enhanced affinity for its protein partner. Structural information can be used to select residues on one or more of the protein interfaces in the complex for alteration by methods such as site-directed mutagenesis or phage display. For example, amino acid positions in growth hormone which were allowed to vary were chosen in part from the crystal structure of the complex of growth hormone bound to two molecules of the human growth hormone extracellular region (Lowman and Wells, 1993, J. Mol. Biol. 234: 564-578.). Using a model of the granulocyte colony-stimulating factor (G-CSF) receptor ligand binding domain, residues of the receptor were chosen for mutagenesis by analogy with the structure of human growth hormone bound to its receptors (Layton et al., 1997, J Biol. Chem. 272: 29735-29741.). Some of the mutant G-CSF receptors were found to bind G-CSF with slightly enhanced affinity. The structure of the complex could also be used to design mutations which would potentially increase the binding affinity, for example by increasing the amount of hydrogen bonds and/or van der Waals interactions across the interface.

The modification of protein residues to enhance protein binding affinity is not restricted to those residues in the relevant protein-protein interfaces. Modification of residues outside of an interface may lead to alterations due to changes in the long-range electrostatic interactions between the two interacting proteins which changes the rate of association and subsequently the equilibrium binding constant (Seizer and Schreiber, 1999, J Mol Biol. 287: 409-419.; Seizer et al, 2000, Nat Struct Biol. 7: 537-541.). The contribution of mutations to the association rate can be calculated and has been used to increase the association rate (without greatly changing the dissociation rate) and the affinity of beta-lactamase inhibitory protein to TEM1 beta-lactamase by a factor of 250 (Seizer et al., 2000).

By “variant” we mean that the natural sequence of IL-6 has been modified by one or more point mutations, insertions of amino acids, deletions of amino acids or replacement of amino acids, in particular using non-natural amino acids such as D-isomers of natural amino acids, 2,4-diaminobutyric acid, α-amino isobutyric acid, 4-aminobutyric acid, 2-aminobutyric acid, 6-amino hexanoic acid, 2-amino isobutyric acid, 3-amino propionic acid, ornithine, norleucine, norvaline, hydroxyproline, sarcosine, citrulline, homocitrulline, cysteic acid, t-butylglycine, t-butylalanine, phenylglycine, cyclohexylalanine, beta-alanine, fluoro-amino acids, designer amino acids such as β-methyl amino acids, Cα-methyl amino acids, Nα-methyl amino acids, β-naphthalimo amino acids and amino acid analogues in general.

Accordingly, in a further aspect the present invention provides a method of selecting or designing a compound that interferes with the formation of the IL-6, IL-6R, gp130 hexameric complex, the method comprising the step of assessing the stereochemical complementarity between the compound and a topographic region of the complex, wherein the complex is characterised by

In another aspect the present invention provides a computer for producing a three-dimensional representation of a molecule or molecular complex, wherein the computer comprises:

- (a) a machine-readable data storage medium comprising a data storage material encoded with machine-readable data, wherein the machine readable data comprise the atomic coordinates of the IL-6, IL-6R, gp130 hexameric complex as shown in Appendix II, or structural coordinates having a root mean square deviation from the backbone atoms of said amino acids of not more than 1.5A, or one or more subsets of said amino acids, or one or more subsets of the coordinates shown in Appendix II by whole body translations and/or rotations;

The compound may interfere with hexamer formation in a number of ways. For example the compound may bind or interact with one of the molecules at or near one or more of the specified residues or corresponding regions and by steric overlap and/or electrostatic repulsion prevent natural ligand binding or dimer formation. Alternatively the compound may bind to one of the molecules so as to interfere allosterically with hexamer formation.

It is presently preferred, however, that the compound binds or interacts with at least one of the molecules positioned at the interfaces.

Accordingly in a preferred embodiment of the present invention, the method comprises selecting or designing a compound which has portions that match at least one region of the molecules that make up the hexamer, in which the region is selected from the group consisting of;

- (i) amino acids 20, 24, 25, 27, 29, 31, 32, 35, 36, 39, 40-42, 45, 51, 52, 56, 60, 62-64, 69-71, 75-79, 93, 94, 110-115, 117-119, 121-123, 125, 126, 128-147, 151, 152, 155, 159, 161-169, 172, 173, 176, 177, 179, 180, 183 and 184 of IL-6 and combinations thereof; and

- (iii) amino acids 1, 6, 107, 108, 135-139, 161-169, 190, 193, 226-231 and 277-281 of IL-6R and combinations thereof.

In a still further aspect the present invention consists in a crystalline composition comprising IL-6 receptor or portion thereof or variant of these.

As will be readily understood by persons skilled in this field the methods of the present invention provide a rational method for designing and selecting compounds which interact with the IL-6 receptor. In the majority of cases these compounds will require further development in order to increase activity. Such further development is routine in this field and will be assisted by the structural information provided in this application. It is intended that in particular embodiments the methods of the present invention includes such further developmental steps.

Accordingly, in another aspect the present invention consists in a method of designing or selecting a compound which modulates IL-6R signalling, the method comprising subjecting a compound obtained by a method according to any one of the previous aspects of the present invention to biological screens and assessing the ability of the compound to modulate IL-6R signalling.

In yet a further aspect, the invention provides a method of utilizing molecular replacement to obtain structural information about a molecule or a molecular complex of unknown structure, comprising the steps of:

- (i) crystallising said molecule or molecular complex;
- (ii) generating an X-ray diffraction pattern from said crystallized molecule or molecular complex;
- (iii) applying at least a portion of the structure coordinates set forth in Appendix I to the X-ray diffraction pattern to generate a three-dimensional electron density map of at least a portion of the molecule or molecular complex whose structure is unknown.

The structure of the IL-6 receptor can be used to design mutant IL-6 receptor molecules or fragments thereof for use as therapeutics.

Accordingly, the present invention also provides a compound comprising an extracellular fragment of IL-6R, wherein the extracellular fragment is modified at one or more amino acids of IL-6R selected from the group consisting of:

- (i) amino acids 106-110, 133-138, 160-168, 190-193, 227-233, 250-256 and 276-281; or
- (ii) amino acids 1-5, 19-23, 65-69, 93-99, 118, 119, 132-141, 166-172, 179-196, 241-250, 261, 262, 272-276 and 282-290; or
- (iii) amino acids 11, 45, 46, 55, 62-6, 69-72, 75, 81, 55, 90-93, 122-124 and 178; or
- (iv) amino acids 233-239, 244-248 and 270-290; or
- (v) amino acids 1, 6, 107, 108, 135-139, 161-169, 190, 193, 226-231 and 277-281.

In a preferred embodiment of this aspect of the invention, the modification is made to an amino acid which is not listed in Table 2.

In a further preferred embodiment, the IL-6R fragment comprises residues 1 to 325 of SEQ ID NO:1.

In one embodiment of this aspect, the modification increases the affinity of the IL-6R fragment for one or more of its natural ligands when compared to the unmodified fragment.

It will be appreciated by those skilled in the art that these compounds may be formulated into pharmaceutical compositions and used to treat diseases associated with signaling of the IL-6R.

The present inventors have now obtained three dimensional structural information about the IL-6 receptor which enables a more accurate understanding of how the binding of ligand leads to signal transduction. Such information provides a rational basis for the development of ligands for specific therapeutic applications, something that heretofore could not have been predicted de nova from available sequence data.

Those of skill in the art will understand that a set of structural coordinates determined by X-ray crystallography is not without standard error. For the purposes of this invention, any set of structure coordinates for IL-6R or an IL-6R complex that have a root mean square derivation of protein backbone atoms of less than 1.5 Å when superimposed (using backbone atoms) on the structure coordinates listed in Appendix I or II shall be considered identical.

The precise mechanisms underlying the binding of agonists and antagonists to the IL-6 receptor are not fully clarified. However, the binding of ligands to the receptor site, preferably with an affinity in the order of 10⁻⁸M or higher, is understood to arise from enhanced stereochemical complementarity relative to naturally occurring IL-6 receptor ligands.

Such stereochemical complementarity, pursuant to the present invention, is characteristic of a molecule that matches intra-site surface residues lining the groove of the receptor site as enumerated by the coordinates set out in Appendix I. By “match” we mean that the identified portions interact with the surface residues, for example, via hydrogen bonding or by non-covalent Van der Waals and Coulomb interactions which promote desolvation of the biologically active compound within the site, in such a way that retention of the biologically active compound within the groove is favoured energetically.

Substances which are complementary to the shape and electrostatics or chemistry of the receptor site characterised by amino acids positioned at atomic coordinates set out in Appendix I will be able to bind to the receptor, and when the binding is sufficiently strong, substantially prohibit binding of the naturally occurring ligands to the site.

It will be appreciated that it is not necessary that the complementarity between ligands and the receptor site extend over all residues lining the groove in order to inhibit binding of the natural ligand.

In general, the design of a molecule possessing stereochemical complementarity can be accomplished by means of techniques that optimize, chemically and/or geometrically, the “fit” between a molecule and a target receptor. Known techniques of this sort are reviewed by Sheridan and Venkataraghavan, 1987, Acc. Chem Res. 20: 322; Goodford, 1984, J. Med. Chem. 27: 557; Beddell, 1985, Chem. Soc. Reviews 279; Hol, 1986, Angew. Chem. 25: 767, Verlinde and Hol, 1984, Structure 2: 577, Walters et al., 1998, Drug Discovery Today 3: 160; Langer and Hoffmann, 2001, Current Pharmaceutical Design 7: 509; Good, 2001, Current Opinion in Drug Disc. Devel. 5, 301; Gane and Dean, 2000, Curr. Opinion Struct. Biol. 10: 401. the respective contents of which are hereby incorporated by reference. See also Blundell et al., 1987, Nature 326: 347 (drug development based on information regarding receptor structure) and Loughney et al., 1999, Med. Chem. Res. 9: 579 (database mining application on the growth hormone receptor).

There are two preferred approaches to designing a molecule, according to the present invention, that complements the stereochemistry of the IL-6 receptor. The first approach is to in silico directly dock molecules from a three-dimensional structural database, to the receptor site, using mostly, but not exclusively, geometric criteria to assess the goodness-of-fit of a particular molecule to the site. In this approach, the number of internal degrees of freedom (and the corresponding local minima in the molecular conformation space) is reduced by considering only the geometric (hard-sphere) interactions of two rigid bodies, where one body (the active site) contains “pockets” or “grooves” that form binding sites for the second body (the complementing molecule, as ligand).

This approach is illustrated by Kuntz et al., 1982, J. Mol. Biol. 161: 269, and Ewing et al., 2001, J. Comput-Aid. Mol. Design 15: 411, the contents of which are hereby incorporated by reference, whose algorithm for ligand design is implemented in a commercial software package, DOCK version 4.0, distributed by the Regents of the University of California and further described in a document, provided by the distributor, which is entitled “Overview of the DOCK program suite” the contents of which are hereby incorporated by reference. Pursuant to the Kuntz algorithm, the shape of the cavity represented by the IL-6 receptor site is defined as a series of overlapping spheres of different radii. One or more extant databases of crystallographic data, such as the Cambridge Structural Database System maintained by Cambridge University (University Chemical Laboratory, Lensfield Road, Cambridge CB2 1EW, U.K.), the Protein Data Bank maintained by the Research Collaboratory for Structural Bioinformatics (Rutgers University, N.J., U.S.A.), LeadQuest (Tripos Associates, Inc., St. Louis, Mo.), Available Chemicals Directory (Molecular Design Ltd., San Leandro, Calif.), and the NCI database (National Cancer Institute, U.S.A) is then searched for molecules which approximate the shape thus defined.

Molecules identified in this way, on the basis of geometric parameters, can then be modified to satisfy criteria associated with chemical complementarity, such as hydrogen bonding, ionic interactions and Van der Waals interactions. Different scoring functions can be employed to rank and select the best molecule from a database. See for example Bohm and Stahl, 1999, M. Med. Chem. Res. 9: 445. The software package FlexX, marketed by Tripos Associates, Inc. (St. Louis, Mo.) is another program that can be used in this direct docking approach (see Rarey, M. et al., J. Mol. Biol. 1996, 261: 470).

The second preferred approach entails an assessment of the interaction of respective chemical groups (“probes”) with the active site at sample positions within and around the site, resulting in an array of energy values from which three-dimensional contour surfaces at selected energy levels can be generated. The chemical-probe approach to ligand design is described, for example, by Goodford, 1985, J. Med. Chem. 28:849, the contents of which are hereby incorporated by reference, and is implemented in several commercial software packages, such as GRID (product of Molecular Discovery Ltd., West Way House, Elms Parade, Oxford OX2 9LL, U.K.). Pursuant to this approach, the chemical prerequisites for a site-complementing molecule are identified at the outset, by probing the active site with different chemical probes, e.g., water, a methyl group, an amine nitrogen, a carboxyl oxygen, and a hydroxyl. Favoured sites for interaction between the active site and each probe are thus determined, and from the resulting three-dimensional pattern of such sites a putative complementary molecule can be generated. This may be done either by programs that can search three-dimensional databases to identify molecules incorporating desired pharmacophore patterns or by programs which using the favoured sites and probes as input perform de novo design.

Programs suitable for searching three-dimensional databases to identify molecules bearing a desired pharmacophore include: MACCS-3D and ISIS/3D (Molecular Design Ltd., San Leandro, Calif.), ChemDBS-3D (Chemical Design Ltd., Oxford, U.K.), and Sybyl/3 DB Unity (Tripos Associates, Inc., St. Louis, Mo.).

Programs suitable for pharmacophore selection and design include: DISCO (Abbott Laboratories, Abbott Park, Ill.), Catalyst (Accelrys, San. Diego, Calif.), and ChemDBS-3D (Chemical Design Ltd., Oxford, U.K.).

Databases of chemical structures are available from a number of sources including Cambridge Crystallographic Data Centre (Cambridge, U.K.), Molecular Design, Ltd., (San Leandro, Calif.), Tripos Associates, Inc. (St. Louis, Mo.), and Chemical Abstracts Service (Columbus, Ohio).

De novo design programs include Ludi (Biosym Technologies Inc., San Diego, Calif.), Leapfrog (Tripos Associates, Inc.), Aladdin (Daylight Chemical Information Systems, Irvine, Calif.), and LigBuilder (Peking University, China).

Those skilled in the art will recognize that the design of a mimetic may require slight structural alteration or adjustment of a chemical structure designed or identified using the methods of the invention.

The invention may be implemented in hardware or software, or a combination of both. However, preferably, the invention is implemented in computer programs executing on programmable computers each comprising a processor, a data storage system (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. Program code is applied to input data to perform the functions described above and generate output information. The output information is applied to one or more output devices, in known fashion. The computer may be, for example, a personal computer, microcomputer, or workstation of conventional design.

Each program is preferably implemented in a high level procedural or object-oriented programming language to communicate with a computer system. However, the programs can be implemented in assembly or machine language, if desired. In any case, the language may be compiled or interpreted language.

Each such computer program is preferably stored on a storage medium or device (e.g., ROM or magnetic diskette) readable by a general or special purpose programmable computer, for configuring and operating the computer when the storage media or device is read by the computer to perform the procedures described herein. The inventive system may also be considered to be implemented as a computer-readable storage medium, configured with a computer program, where the storage medium so configured causes a computer to operate in a specific and predefined manner to perform the functions described herein.

Modulators of II-6 Receptors

The present invention provides the atomic coordinates of the crystal structure of the soluble extracellular portion of an IL-6 receptor alpha subunit and the atomic coordinates of the crystal structure of a hexameric complex consisting of both IL-6 receptor subunits (sIL-6α and gp130) together with the ligand IL-6. As described above, these coordinates can be used in methods of the invention to screen in silico, for potential modulators of IL-6R activity.

Accordingly, the present invention provides a compound which modulates the activity of an IL-6R, said compound identified/identifiable by a method of the invention. Preferably said compound is specific for IL-6R, for example said compounds exhibits at least 10 times, preferably at least 50 times more activity towards IL-6R than other cytokine receptors, such as an IGR receptor.

In one embodiment, said method comprises the step of assessing the stereochemical complementarity between the compound and a topographic region of the receptor, wherein the receptor comprises:

- (i) amino acids 1-299 of the IL-6 receptor positioned at atomic coordinates as shown in Appendix I, or structural coordinates having a root mean square deviation from the backbone atoms of said amino acids of not more than 1.5 Å; or
- (ii) one or more subsets of said amino acids related to the coordinates shown in Appendix I by whole body translations and/or rotations.

Preferably the topographic region of the IL-6 receptor is selected from:

- (i) a ligand binding surface defined by residues 106-110, 133-138, 160-168, 190-193, 227-233, 250-256 or 276-281 and combinations thereof;
- (ii) the homodimer interface defined by resides 1-5, 19-23, 65-69, 93-99, 118, 119, 132-141, 166-172, 179-196, 241-250, 261, 262, 272-276 or 282-290 and combinations thereof;
- (iii) residues 11, 45, 46, 55, 62-66, 69-72, 75, 81, 88, 90-93, 122-124 and 178; and
- (iv) residues 233-239, 244-248 and 270-290.

Compounds designed according to the methods of the present invention may be assessed by a number of in vitro and in vivo assays of hormone function. For example, the identification of IL-6 receptor antagonists of may be undertaken using a solid-phase receptor binding assay. Potential antagonists may be screened for their ability to inhibit the binding of europium-labelled IL-6 receptor ligands to soluble, recombinant IL-6 receptor in a microplate-based format. Europium is a lanthanide fluorophore, the presence of which can be measured using time-resolved fluorometry. The sensitivity of this assay matches that achieved by radioisotopes, measurement is rapid and is performed in a microplate format to allow high-sample throughput, and the approach is gaining wide acceptance as the method of choice in the development of screens for receptor agonists/antagonists (see Apell et al., J. Biomolec. Screening 3:19-27, 1998: Inglese et al., Biochemistry 37:2372-2377, 1998).

Binding affinity and inhibitor potency may be measured for candidate inhibitors using biosensor technology.

Biological assays to measure the activity of IL-6R are well known in the field. In particular various assay systems are described in Hammacher et al., 1998, J. Biol. Chem. 273, 22701-22707; and Hammacher et al, 1994, Protein Science, 3, 2280-2293, the disclosures of which are incorporated by reference.

The methods of the invention have been used to identify a number of compounds that potentially are agonist or antagonists of IL-6 activity. These compounds have subsequently been tested in vitro to determine biological activity and specificity. Compounds showing specific IL-6R agonist or antagonist activity have been modeled using the crystal structure of the invention to determine the site of binding and the amino acid residues of IL-6Rα that are contacted by the compounds. These results have enabled the generation of general structural criteria for both a class of antagonists and a class of agonists that occupy all or part of the IL-6 ligand binding surface defined by loops L1 to L7 as described above.

Uses of Modulators of IL-6R

The compounds described above may be used to modulate IL-6R activity in cells, i.e. activate or inhibit IL-6R activity. Given that aberrant IL-6R/IL-6 activity is implicated in a range of disorders, the compounds described above may also be used to treat, ameliorate or prevent disorders characterised by abnormal IL-6 signalling. Examples of such disorders include multiple myeloma, rheumatoid arthritis, Castleman's disease, AIDS, mesangial proliferative glomerulonephritis, Kaposi's sarcoma, sepsis, osteoporosis and psoriasis.

Administration

Compounds of the invention, i.e. modulators of IL-6R identified or identifiable by the screening methods of the invention, may preferably be combined with various components to produce compositions of the invention. Preferably the compositions are combined with a pharmaceutically acceptable carrier or diluent to produce a pharmaceutical composition (which may be for human or animal use).

The formulation will depend upon the nature of the compound and the route of administration but typically they can be formulated for topical, parenteral, intramuscular, oral, intravenous, intra-peritoneal, intranasal inhalation, lung inhalation, intradermal or intra-articular administration. The compound may be used in an injectable form. It may therefore be mixed with any vehicle which is pharmaceutically acceptable for an injectable formulation, preferably for a direct injection at the site to be treated, although it may be administered systemically.

The pharmaceutically acceptable carrier or diluent may be, for example, sterile isotonic saline solutions, or other isotonic solutions such as phosphate-buffered saline. The compounds of the present invention may be admixed with any suitable binder(s), lubricant(s), suspending agents), coating agent(s), solubilising agent(s). It is also preferred to formulate the compound in an orally active form.

In general, a therapeutically effective daily oral or intravenous dose of the compounds of the invention, including compounds of the invention and their salts, is likely to range from 0.01 to 50 mg/kg body weight of the subject to be treated, preferably 0.1 to 20 mg/kg. The compounds of the invention and their salts may also be administered by intravenous infusion, at a dose which is likely to range from 0.001-10 mg/kg/hr.

Tablets or capsules of the compounds may be administered singly or two or more at a time, as appropriate. It is also possible to administer the compounds in sustained release formulations.

Typically, the physician will determine the actual dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient. The above dosages are exemplary of the average case. There can, of course, be individual instances where higher or lower dosage ranges are merited, and such are within the scope of this invention.

For some applications, preferably the compositions are administered orally in the form of tablets containing excipients such as starch or lactose, or in capsules or ovules either alone or in admixture with excipients, or in the form of elixirs, solutions or suspensions containing flavouring or colouring agents.

The compositions (as well as the compounds alone) can also be injected parenterally, for example intracavernosally, intravenously, intramuscularly or subcutaneously. In this case, the compositions will comprise a suitable carrier or diluent.

For parenteral administration, the compositions are best used in the form of a sterile aqueous solution which may contain other substances, for example enough salts or monosaccharides to make the solution isotonic with blood.

For buccal or sublingual administration the compositions may be administered in the form of tablets or lozenges which can be formulated in a conventional manner.

For oral, parenteral, buccal and sublingual administration to subjects (such as patients), the daily dosage level of the compounds of the present invention and their pharmaceutically acceptable salts and solvates may typically be from 10 to 500 mg (in single or divided doses). Thus, and by way of example, tablets or capsules may contain from 5 to 100 mg of active compound for administration singly, or two or more at a time, as appropriate. As indicated above, the physician will determine the actual dosage which will be most suitable for an individual patient and it will vary with the age, weight and response of the particular patient.

The routes of administration and dosages described are intended only as a guide since a skilled practitioner will be able to determine readily the optimum route of administration and dosage for any particular patient depending on, for example, the age, weight and condition of the patient.

The present invention will now be described further with reference to the following examples, which are illustrative only and non-limiting. The examples refer to the figures:

Methods

Expression, Purification and Crystallization of sIL-6R

Monomeric sIL-6R was purified from the conditioned medium of glycosylation defective mutant Chinese hamster ovary (CHO) cell line Lec3.2.8.1 (Stanley, 1989, Mol. Cell Biol. 9: 377-383), transfected with the construct pEE14sIL6RL325, which encodes sIL-6R. Briefly, sIL-6R transformed Lec3.2.8.1 cells were grown in fermentation apparatus with a working volume of 1.25 L (New Brunswick Celligen Plus fermenter, New Brunswick, USA). Conditioned media was concentrated 20-fold by ultrafiltration. sIL-6R was purified from concentrated Lec3.2.8.1 cell media by binding to a 5 mL column of human IL-6-Sepharose. SIL-6R was further purified by preparative size-exclusion chromatography and concentrated to 10 mg/mL using a 10000 MWCO centrifugal concentrator (Centricon, Millipore, USA).

The protein (8 mg/ml in 5 mM Tris-HCl pH 8.0) was crystallised in hanging drops by vapour diffusion against a reservoir containing 50 mM ammonium sulphate, 18% PEG 3350, 2.5 mM Sodium citrate and at pH 5.6. Crystals grew in the space group P4₃2₁2 (a=51.4 Å, c=305.4 Å) with 51% solvent. To ensure isomorphism for heavy metal derivatives 0.1% gluteraldehyde was added to the well solution for 16 hrs. Crystals were then transferred to a stabilising solution of 0.1M lithium sulphate with 2.5 mM Tris-HCl at pH 6.5, and finally to a freezing solution of 20% PEG 3350, 16% glycerol, 0.1 M lithium sulphate, 2.5 mM sodium citrate and 2.5 mM Tris-HCl at pH 6.5.

Diffraction Data

X-ray data were collected from crystals flash-frozen to 100K in a nitrogen stream. Three data sets were collected for each of the native, and two platinum derivatives (PIP: di-u-iodo-bis(ethylene-diamine)-di-platinum(II)nitrate; PTN: K2Pt(NO₂)₄). Three data sets were collected for each native and two derivatives. A data set with the c* axis parallel to the spindle, one perpendicular to the spindle axis and one low resolution data set, using R-AXIS II and IV image-plate detectors fitted with both mirror and monocapillary optics (Balaic et al., 1996, J. Synchrotron Rad. 3: 289-295) respectively. A 2.4 Å native data set was collected at the Advance Photon Source (Argonne, U.S.A.) on beam line BM14C using an ADSC Quantum-4 CCD-detector. All data sets were collected at 0.5° or 1.0° oscillations and processed and scaled using HKL (Otwinowski and Minor, 1997, Macromolec. Crystallog. Pt A. 276: 307-326) (Table 1).

Structure Solution.

The heavy atom sites of the PIP and PTN derivatives were determined by Patterson methods (CCP4, 1994, Acta Crystallogr. D. Biol. Crystallogr. 50: 760-763) and SOLVE (Terwilliger and Berendzen, 1999, Acta Crystallogr. D. Biol. Crystallogr. 55: 849-861). The space group and hand of the heavy atom sites was determined using the heavy atom anomalous data from both derivatives. The positions of sites were refined to 4 Å using SHARP (de la Fortelle and Bricogne, 1997, Macromolec. Crystallog. Pt A. 276: 472-494) and phasing statistics are shown on Table 1. The 4 Å solvent-flattened (51% solvent) MIRAS-phased electron density map was skeletonised and used to trace the C_□chain of the protein. This map clearly showed the CBD module, and the Ig domain. A partial atomic model of the FnIII domains and part of the Ig domain was built using Lego fragments in “O” (Jones et al., 1991, Acta Crystallogr. A. 47: 110-119). N-linked carbohydrate, were included, at asparagines N36, N74, N₂O₂and N226 and 80 solvent molecules. The disulfide bonds were consistent with the earlier mass spectrometric data. The model was then refined using CNS (Brunger et al., 1998, Acta Crystallogr. D. Biol Crystallogr. 54: 905-921), extending the resolution to 2.4 Å by an iterative process involving model rebuilding and gradual identification and refinement of the residues on the longer loops linking the strands. The quality of the electron density and the thermal parameters of the Ig domain were poorer than the CBD indicating a higher degree of disorder. Residues 1 to 5 and 82 to 84 were set to zero occupancy as the density was poor and residues beyond 299 (C-terminus) were not observable. The side chains of loops 49 to 52 and 136 to 138 appeared highly mobile or disordered. Additional solvent (including two sulphate ions) was added during the course of the refinement. A previously reported cysteine disulfide bonded to the free C192 was observed and built into the model. The final R-factor was 0.22 (R-free of 0.29 over 5% of the data) with r.m.s.d. in bond lengths and angles being 0.015 Å and 1.96° respectively with overall anisotropic temperature factors of B₁₁=B₂₂=−6.4 Å₂and B₃₃=12.7 Å₂added to the individual atomic isotropic B-values.

Modeling the Complex

The model of the hexameric interleukin-6 signal transduction complex (see FIG. 6a.) was assembled using a parallel version of the protein-protein docking algorithm FTDOCK 2.0 (Gabb et al., 1997, J. Mol. Biol. 272: 106-120). The protein chains were taken from the NMR structure (PDB code 1IL6) for IL-6 (Xu et al., 1997, J. Mol. Biol. 268: 468-481), the X-ray structure of gp130 from the viral IL-6 gp130 complex (Chow et al., 2001, Science 291: 2150-2155) (PDB code 1I1R) and the IL-6R dimer. Using a grid spacing of 0.5 Å and incorporating electrostatic treatment the following protein/protein docking calculations were undertaken. IL-6 was docked with IL-6R, IL-6 with IL-6R dimer, IL-6 with gp130 and gp130 to IL-6R. Complexes were re-scored (Moont et al., 1999, Proteins 35: 364-373) and the top ranking complexes satisfying the available mutational data (Table 2, Salvati et al., 1995, J. Biol. Chem. 270: 12242-12249) was subject to rigid body refinement and side-chain rotamer optimization using the program MULTIDOCK (Jackson et al., 1998, J. Mol. Biol. 276: 265-285). There was no significant difference in the docking solutions produced for IL-6 to IL-6R and IL-6 to the IL-6R dimer so the solutions of IL-6 to IL-6R dimer were used, with each alpha chain in the dimer binding its cognate IL-6 for assembly of the complex. The final complex was built by superimposing the chains in common from the best solutions using INSIGHTII (Accelrys Inc, San Diego, Calif., USA). The resulting complex was then minimized using CNS (Brunger et al., 1998), with a harmonic restraint applied to the α-carbon backbone.

Results and Discussion

The IL-6R Extracellular Structure

The complete extracellular region of human IL-6R was expressed and secreted from the Chinese hamster ovary (CHO) cell line, Lec3.2.8.1, which produces carbohydrate-deficient glycoprotein (Stanley, 1989). This was necessary because normal CHO cell lines produce heterogeneously glycosylated protein, which did not crystallise. The Lec3.2.8.1 cell secretes a form of the extracellular domain of IL-6R (residues 1 to 325) which was purified and crystallized to diffract to 2.4 Å. The IL-6R 3-dimensional structure was determined by multiple isomorphous replacement with anomalous scattering (MIRAS) from two heavy atom derivatives.

Our X-ray structure of the extracellular domain of the IL-6R (FIG. 1) consists of the N-terminal Ig domain (D₁, residues 1 to 93) linked to a classical is CBD (D₂, residues 94 to 194; D₃, residues 195 to 299). The first 5 residues of the N-terminus are poorly defined and amino acids past residue 299 are not visible in the X-ray structure. The three domains lie on a similar plane making the receptor a long ‘flat’ structure in which the domains D₂and D₃are connected at about 90° to each other and D₁is connected at about 135° to D₂. Carbohydrate is attached at 4 sites on one of the faces of the molecule (FIG. 1), indicating that this face is unlikely to be involved in either the binding of IL-6 or the formation of the signalling complex with gp130. This conclusion is supported by the expression of functional sIL-6R in Escherichia coli which lacks carbohydrate.

The N-terminal cysteine residue C6 is disulfide bonded to residue C174 in D₂, and there is an unusual β-sheet arrangement of D₁(FIG. 1a). D₁has an S-type Ig topology very similar to the ligand-binding domain of fibroblast growth factor (LBD-FGF)), but the first ‘A’ strand of the 3-stranded β-sheet of the LBD-FGF Ig domain is not observed in IL-6R. It appears that these residues have ‘peeled away’ from the sheet when compared to this strand in LBD-FGF (0.7 Å r.m.s.d. between the α-carbons of the two domain structures excluding the ‘A’ strand atoms). The C-terminus of this domain forms a fifth ‘A′’ strand of what would be a 4-stranded β-sheet in an S-type Ig topology. This arrangement of the ‘A’ strand of the β-sheet could be a result of crystal packing and we suggest there is a degree of flexibility of this domain, which acts as a conformational switch, to allow D₁to rotate up to 20° by β-strand shifting. This flexibility could explain what appears to be a higher degree of disorder in this domain when compared to the other domains as indicated by the higher temperature factors of residues in domain D₁compared to D₂or D₃(mean B values for domains D₁, D₂and D₃are 68 Å², 49 Å²and 44 Å²respectively). The molecules of IL-6R in the crystal are packed head to tail in a double helix arrangement with the helical axis along the 4-fold crystal screw axis in direction of the long cell edge (c-axis) and the pitch and diameter of the helix will vary if the angle between domains D₁and D₂changes. Such flexibility of domains would explain the lack of isomorphism between different crystals of IL-6R that were observed in this study.

A characteristic of the CBD of IL-6R is the long tryptophan-arginine ladder (from the N-terminus end of D₃is R239, F246, R237, W287, R274, W284, Q276) which is also found in other class 1 CBD structures. This ladder incorporates the conserved WSXWS motif (residues 284 to 287 in IL-6R) located in the carboxy terminus region of domain D₃of the CBD (FIG. 2). The polypeptide backbone of the WSXWS sequence has an unusual motif: a left-handed 3₁₀helix similar to a polyproline helix. This helix is stabilised by the stacking of the indole side chains of the two tryptophan residues of the WSXWS sequence with arginine side-chains (R237 and R274), and H-bonding of serine side chain hydroxyls but not by main chain H-bonds. The ladder produces a long surface stripe of positive charge (from the guanidinium and tryptophan indol nitrogens) running along D₃near the inside elbow of D₂-D₃, and a groove formed by the 3₁₀helix running parallel to the stripe (FIG. 2). Although this structure is conserved in other known structures of CBDs its functional role has not as yet been clarified. It could be implicated in the folding of the CBD, complex formation or involved in a general receptor transport system.

Following the paradigm of growth hormone (de Vos et al., 1992), and the available mutational data, it would be expected that IL-6 would bind in the region of the outer elbow formed at the junction of D₂and D₃(FIG. 3), characterised by 4 loops (S106-N110 (L1), K133-P138 (L2), A160-F168 (L3), Q190-G193 (L4)) from D₂and 3 loops (S227-R233 (L5), M250-H256 (L6) and Q276-Q281 (L7)) from D₃(FIG. 3). These loops present a long and narrow (43 Å by 9.5 Å) potential binding area held in place by the rigid D₂and D₃framework of the cytokine binding domains. IL-6 would engage residues in some of these loops.

A Dimer in the Crystal

In the crystal lattice, two molecules of IL-6R are related by a crystallographic 2-fold axis and are closely associated along the length of each molecule (FIG. 4). These two molecules (with a total buried accessible surface area of about 2460 Å²) represent a potential physiological dimer of IL-6R. The association is primarily a hydrophobic contact around the 2-fold axis involving F134 and F168 of domain D₂, the salt-link E97-R274, and hydrogen-bonding of the side chain carboxylate of E283 with the main chain amide of T186. The buried accessible surface area (FIG. 4) of each molecule (surface- and electrostatic-complementarity of 0.722 and 0.728 respectively) is much larger than that of a protein-protein interaction surface in solution (typically ˜800 Å²). Furthermore the buried surface of membrane-associated receptor complexes do not have to be as extensive as their counterparts in solution, since their degrees of freedom are restricted to the two-dimensional surface of the membrane. Hence the dimeric association observed here in the crystal may well represent a complex formed on the cell surface.

The orientation of the monomers with the dimer is such that the interaction is along the carbohydrate-free ‘flat’ face of the molecule (FIG. 5). In this crystal structure, if the 2-fold axis of the dimer is perpendicular to the membrane surface, then domain D₃projects away from the membrane at 45° and D2 points down towards the membrane at 30_o. D₁would then run parallel to the membrane (FIG. 4). The dimer appears as a bridge structure (FIG. 6) similar to the common β-receptor of IL-3, with a 50 Å long tunnel of triangular cross-section (base ˜40 Å; height ˜22 Å).

Structural Implications of Mutations

Mapping of the mutational data onto the crystal structure of IL-6R provide some insights into regions on the surface of IL-6R that are critical to binding of IL-6 and implicated in signalling through gp130. Analysis of these data indicate that most of the mutations, when mapped onto the crystal structure, cause altered binding due to compromised structural integrity of the molecule, in particular mutations in the tryptophan/arginine ladder, cysteines forming disulfide bonds, and buried hydrophobic residues forming the hydrophobic core. The non-structural mutations occur on three clusters on the surface of IL-6R (Table 2, FIG. 5).

There is clearly a cluster of residues (see FIG. 5, Cluster 1) that form the binding site to IL-6. The mutations of residues having the greatest effect on IL-6 binding are those at P162 and E163 from L3; S228, F229, Y230 and R231 from L5 and E278 and F279 from L7 (Table 1). Two of these loops, L5 and L7, are both situated on D₃and this is consistent with the report that D₃by itself is able to bind IL-6 (18). This site at the juncture of D₂and D₃domains, and can be inferred to be primarily responsible for IL-6 binding.

Non-structural mutations in IL-6R that affect gp130 signalling (FIG. 5) can be classified onto two main clusters. The first occurs at a hydrophobic patch (residues F134, F168 and Y169) at the dimer interface (FIG. 5, Cluster 2) located around the crystallographic two fold axis relating the two molecules of the dimer. Mutations here reduce signalling but have no effect on binding. There are also other residues, not included in Cluster 2, on domain D₃in this interface that reduce signalling but not binding (see FIG. 5). These data indicate that mutations that would be expected to interfere with the formation of the IL-6R dimer have a significant effect on IL-6 signalling but not on IL-6 binding. 14 The other cluster of mutations effecting gp130 signalling occurs on a patch of residues (FIG. 5, Cluster 3) centred around residue H261 on domain D₃. Mutational studies in this region of IL-6R were based on the growth hormone paradigm, which demonstrated a contact region between the second CBD domains of the growth hormone complex (de Vos et al., 1992, Science 255: 306-312). This patch is clearly not involved in IL-6 binding or IL-6R dimerisation, but when mutated this region effects signalling. This is most likely a region that is involved in the formation of the IL-6/IL-6R complex with gp130.

It has been predicted previously that two SSFY sequence repeats in IL-6R are involved in binding sites to IL-6. The first repeat S165-Y169 is located in L3 of D₂. Mutations in S167 and Y169 reduce signalling, but this is likely due to the structural importance of these buried residues. F168 is solvent exposed and forms the central part of Cluster 2 that is involved in IL-6R dimer formation, not IL-6 binding. A second aromatic residue, F134, is the other major residue in Cluster 2. The second SSFY repeat (S227-Y230) is located in L5 on D₃of IL-6R (FIG. 3). These residues (apart from S227) are critical to IL-6 binding and are all surface exposed residues.

It has been reported previously that N211, H261 and D262 together form a group of residues that affect signalling but not binding of IL-6 to IL-6R. Surprisingly, these residues cluster with W214 and V259, that when mutated (to N and Q respectively) increase the signalling of IL-6 over wild type. The role of the cysteinyl-cysteine C192 remains unsolved. The residue is on the periphery of the IL-6 binding site. When C192 is mutated to alanine, the binding of IL-6 to IL-6R and signalling are slightly increased. The human IL-6R sequence is the only vertebrate sequence in the database to date that has a cysteine in this position: pig and cow having a tyrosine and mouse, and rat having a leucine.

The Hexameric Signalling Complex

A hexameric complex (FIG. 6a) incorporating the IL-6R dimer can be constructed in a manner that is compatible with the available mutational and functional data present in the literature except for the mutations in Cluster 3, which have no cognate binding partner in this model. Additionally, the placement of the three C-terminal fibronectin type III domains (D₄, D₅and D₆) from gp130 has not been considered. Several orientations of these domains are possible but in the absence of any structural information they are difficult to dock with sufficient surety. Using homology models of these three domains, one can orient in such a way so they contact Cluster 3 on D₃of IL-6R and form a disulfide link proposed between D₅of gp130 underneath the complex as shown schematically in FIG. 6b.

The recent structure of the Ig and CBD domain of gp130 complexed with viral IL-6 reveals a possible dimeric relationship between the human IL-6 and the binding domains of gp130. The dimeric relationship of the viral IL-6/gp130 complex is a crystallographic 2-fold relationship, as in the IL-6R dimer. Incorporating the same dimeric relationship between all the IL-6 binding receptor domains, it is possible to construct a model for the signalling complex (FIG. 6a). In this model, two IL-6 molecules bind to the IL-6R dimer via site I (FIG. 6) followed by two gp130 molecules each binding through sites II and III of different IL-6 molecules in a similar way to the viral IL-6/gp130 fragment complex. The signalling molecule gp130 would bind the IL-6/IL-6R complex with D₃pointing away from the membrane. The remaining three FnIII domains of each gp130 would orientate towards the membrane, and the signalling activated by dimerisation of the gp130 membrane proximal FnIII domains (FIG. 6b) under the bridge of the IL-6R dimer likely through disulfide crosslinking. Although this model is substantially different from current proposed models, it is consistent with the available biological data. Other gp130 signalling complexes (e.g., IL-11) could act through a similar mechanism. A notable feature of this model is the binding orientation of IL-6 to IL-6R is rotated 180° compared to the analogous positions in growth hormone, prolactin and erythropoeitin receptor structures, and the IL-12 structure.

The crystal structure of IL-6R and the model of the hexameric complex will provide the basis for the design of mutations of the proteins involved in this complex. It also enables the design/selection of small molecular weight antagonists and agonists to IL-6 signalling that can be developed into therapeutics targeted to the diseases modulated by IL-6 signalling. The selection of a number of small molecular weight compounds and testing for activity as antagonists or agonists to IL-6 signalling is described below.

Example 2
Screening for Agonist/Antagonists of IL-6R

In Silico Screening

The sIL-6R structural information provided in Appendix I was used in an in silico screen for compounds having complementarity to the ligand binding surfaces of IL-6R defined by loops L1-L7. The screen was conducted on compounds in the NCI database using DOCK and in-house ranking and re-scoring protocols. Briefly, the orientation from the docking algorithm considered as the correct orientation was calculated in a normalised rank-by-number strategy (Wang and Wang, 2001, Journal of Chemical Information and Computer Sciences 41(5):1422-6) using scoring functions based on the DOCK energy function (Kuntz et al., 1982, J. Mol Biol 161: 269-288), SCORE (Wang et al, 1988, J Mol Model 4: 379-394), chemscore (Gohlke et al, 2000, J Mol Biol 295: 337-336), potential of mean force (Muegge et al, 1999, J Med. Chem. 4: 379-394), SMOG (DeWitte et al, 1996, J Am Chem Soc. 118: 11733-11744). The scores associated with each are then re-ranked in a rank-by-rank strategy (Wang and Wang, 2001). The top 100 compounds are then sorted by calculated octanol/water solubility (log P) (Wang, 1997, J. Chem. Inf. Comput. Sci. 37: 615), with compounds with a logP greater than 6 excluded from the hit-list. Representative examples of the top 100 compounds are listed in Table 3.

High Capacity Screening Assay for Detection of Agonists/Antagonists of the IL6/IL6Rα/gp130 Interaction.

Ten of the compounds listed in Table 3 were tested for their ability to modulate binding of IL-6 to IL-6R/gp130. The high throughput screening assay used for this purpose detects the binding of europium-labelled human IL6 (Eu-hIL6) to human soluble interleukin 6 receptor α-chain (hsIL6Rα) and hsgp130 immobilised on the surface of wells of a microtitre plate. The protocol followed was essentially as follows:

Europium Labelling of hIL-6

HIL-6 (2.13 mg, 100 nmol) was mixed with 1 mg (1,500 nmol) of Eu labelling reagent in 100 mM NaHCO₃buffer; pH 9.3 and incubated at 4° C. for 48 h. The Eu-labelled IL-6 was then separated from unreacted labelling reagent and high molecular weight protein aggregates using a Pharmacia Superdex-200 column (HR 16/10) equilibrated in a buffer containing 50 mM Tris-HCl; pH 7.75, 0.9% NaCl, and 0.1% sodium azide. The column was run at a flow rate of 0.5 mL/min and fractions of 0.5 mL were collected.

The fractions were assayed for europium by diluting 10,000-fold in 200 μL of DELFIA enhancement solution and measuring europium fluorescence. The Eu-IL6 eluted (14-15 min) after high molecular weight protein aggregates (11-12 min) and before the unreacted labelling reagent (19 min). The concentration of Eu-IL6 was determined from the absorbance at 280 nm (0.5 AU/mg/mL) and the labelling stoichiometry based on a molecular mass of 21,300.

Screening Assay Protocol

Assays were performed in 384-well black microtitre plates. 50 μL of hsgp130 (2.5 μg/mL in PBS; pH 7.2) was added to each well in columns 1-22 of the assay plates. PBS was added only to wells in columns 23-24. The samples were then incubated at 4° C. overnight. Plates were washed 4 times with 100 μL of DELFIA® Wash Buffer using the EMBLA 384-well plate washer. DELFIA® Assay Buffer (25 μL) was added to all wells using the Multidrop 384-well dispenser.

Test compounds were reconstituted in methanol and transferred (3 μL samples) to the appropriate assay plate wells using the SAGIAN Multimek. Methanol was allowed to evaporate from assay plates by incubating at room temperature for 15 minutes.

A solution containing Eu-hIL6 (90 ng/mL) and hsIL6Rα (2 μg/mL) was prepared in DELFIA® Assay Buffer and added (25 μL samples) to all plate wells using the Multidrop 384-well dispenser. The plates were incubated at room temperature for 2 hours. Plate wells were then washed 8 times with 100 μL/well of DELFIA® Wash Buffer using the EMBLA 384-plate washer. DELFIA® Enhancement Solution (75 μL) was added to each well and the plates were then covered and incubated overnight at room temperature. Plates were then read on the Wallac 1420 Victor Multilabel Counter set at the Europium protocol for 384-well plates.

In order to examine specificity, the compounds were also assayed against the IGF receptor system in an identical manner.

Results of the compounds tested using this assay procedure are shown in FIG. 7. FIG. 7A shows the results obtained using the gp130/IL-6Rα/IL-6 system, and FIG. 7B shows the results obtained using the IGF-1R/IGF-1 system. These results show that compound 39914 acts specifically as an antagonist of IL-6 binding to IL-6R/gp130 and that compounds 17791 and 56681 act specifically as agonists of IL-6 binding to IL-6R/gp130.

Modelling studies have shown that compounds 39914 and 17791 are likely to interact with IL-6R via the groove on IL-6R defined by residues Phe229, Tyr230, Phe279, Glu278, Glu163, Cys192, Pro162 and Leu108 (see FIG. 8).

Deduction of Dimer Coordinates

For a dimer comprising a first monomer unit and a second monomer unit, the structures coordinates (in Å) of the first monomer unit are defined by X1, Y1 and Z1 as set forth above, and the structure coordinates of the second monomer unit (in Å) are defined by X2, Y2 and Z2, which can be deduced from the following equations:

X2=51.13−Y1 (1)
Y2=51.13−X1 (2)
Z2=151.7−Z1 (3)
