Description

WO 00/09653 PCTIUS98/14k34 METHOD OF INHIBITING CATHEPSIN K
Field of the Invention 5 This invention relates to a method of inhibiting cathepsin K by the utilization of the physical and spacial characteristics that allow for the interaction of the propeptide with the active site of the enzyme. This interaction inhibits the activity of cathepsin K and this information is useful in the design of specific chemical compounds for treating diseases in which said inhibition is indicated, such as 10 osteoporosis and periodontal disease. This invention also relates to a novel crystalline structure of procathepsin K, the identification of the propeptide bound to the catalytic active site for this enzyme and methods enabling the design and selection of inhibitors of said active site.
15 Backgyround of the Invention Cathepsin K is a member of the family of enzymes which are part of the papain superfamily of cysteine proteases. Cathepsins B, H, L, N and S have been described in the literature. Recently, cathepsin K polypeptide and the cDNA
encoding such polypeptide were disclosed in U.S. Patent No. S,S01,969 (called 20 cathepsin O therein). Cathepsin K has been recently expressed, purified, and characterized. Bossard, M. J., et al., (1996) J. Biol. Chem. 271, 12517-12524;
Drake, F.H., et al., (1996) J. Biol. Chem. 271, 12511-12516; Bromme, D., et al., ( 1996) J. Biol. Chem. 271, 2126-2132.
Cathepsin K has been variously denoted as cathepsin O, cathepsin X or 25 cathepsin 02 in the literature. The designation cathepsin K is considered to be the more appropriate one (name assigned by Nomenclature Committee of the International Union of Biochemistry and Molecular Biology).
Cathepsins of the papain superfamily of cysteine proteases function in the normal physiological process of protein degradation in animals, including humans, 30 e.g., in the degradation of connective tissue. However, elevated levels of these enzymes in the body can result in pathological conditions leading to disease.
Thus, cathepsins have been implicated in various disease states, including but not limited to, infections by pneumocystis carinii, trypsanoma cruzi, trypsanoma brucei brucei, and Crithidia fusiculata; as well as in schistosomiasis malaria, tumor metastasis, 35 metachromatic leukodystrophy, muscular dystrophy, amytrophy, and the like.

gingivallis, -called gingipains, have been implicated in the pathogenesis of gingivitis.

Cathepsin K is believed to play a causative role in diseases of excessive bone 5 or cartilage loss. Bone is composed of a protein matrix in which spindle- or plate-shaped crystals of hydroxyapatite are incorporated. Type I Collagen represents the major structural protein of hone comprising approximately 90% of the structural protein. The remaining 10% of matrix is composed of a number of non-collagenous proteins, including osteocalcin, proteoglycans, osteopontin, osteonectin, 10 thrombospondin, fibronectin, and bone sialoprotein. Skeletal bone undergoes remodeling at discrete foci throughout life. These foci, or remodeling units, undergo a cycle consisting of a bone resorption phase followed by a phase of bone replacement.
Bane resorption is carried out by osteoclasts, which are multinuclear cells of 15 hematopoietic lineage. The osteoclasts adhere to the bone surface and form a tight sealing zone, followed by extensive membrane ruffling on their apical (i.e., resorting) surface. This creates an enclosed extracellular compartment on the bone surface that is acidified by proton pumps in the ruffled membrane, and into which the osteoclast secretes proteolytic enzymes. The low pH of the compartment 20 dissolves hydroxyapatite crystals at the bone surface, while the proteolytic enzymes digest the protein matrix. In this way, a resorption lacuna, or pit, is formed. At the end of this phase of the cycle, osteoblasts lay down a new protein matrix that is subsequently mineralized. In several disease states, such as osteoporosis and Paget's disease, the normal balance between bone resorption and formation is disrupted, and 25 there is a net loss of bone at each cycle. Ultimately, this leads to weakening of the bone and may result in increased fracture risk with minimal trauma.
The abundant selective expression of cathepsin K in osteoclasts strongly suggests that this enzyme is essential for bone resorption. Thus, selective inhibition of cathepsin K may provide an effective treatment for diseases of excessive bone 30 loss, including, but not limited to, osteoporosis, gingival diseases such as gingivitis and periodontitis, Paget's disease, hypercalcemia of malignancy, and metabolic bone disease. Cathepsin K levels have also been demonstrated to be elevated in chondroclasts of osteoarthritic synovium. Thus, selective inhibition of cathepsin K
may also be useful for treating diseases of excessive cartilage or matrix degradation, 35 including, but not limited to, osteoarthritis and rheumatoid arthritis.
Metastatic neoplastic cells also typically express high levels of proteolytic enzymes that WO 00!09653 PCTlUS98/14~34 degrade the surrounding matrix. Thus, selective inhibition of cathepsin K may also be useful for treating certain neoplastic diseases.
Surprisingly, the propeptide of cathepsin K exhibits characteristics that allow for the interaction of the propeptide with specific residues of the active site of 5 cathepsin K and this information is useful in the design of specific chemical compounds as inhibitors of cathepsin K and would be useful for treating diseases in which inhibition of bone resorption is indicated, such as osteoporosis and periodontal disease. Thus, this invention relates to the method of inhibiting cathepsin K using the crystal structure of procathepsin K hereinbelow defined.
Summary of the Invention In one aspect, the present invention provides a method for designing compounds to inhibit cathepsin K with certain structural, physical and spacial characteristics that allow for the interaction of said compounds with specific residues 15 of the active site of the enzyme in a manner similar to the interaction of the propeptide with the enzyme active site.

Detailed Description of the Invention The present invention provides a novel cysteine protease proenzyme crystalline structure, and methods of use of the crystalline form and active site interactions with the inhibitory propeptide to identify protease inhibitor compounds.
In particular, the present invention provides a method for inhibiting cathepsin K by designing compounds with certain structural, physical and spatial characteristics that allow for the interaction of said compounds with specific residues of the active site of the enzyme based on the structure of the proenzyme. This interaction inhibits the activity of cathepsin K and, thus, treats diseases in which bone resorption is a factor.

In still another aspect, the present invention provides a novel protease proenzyme composition, specifically a novel procathepsin K composition, 3o characterized by a three dimensional catalytic site formed by the atoms of the amino acid residues listed in Table IV herein.
A key aspect of this invention provides a method of inhibiting cathepsin K
which comprises administering to a mammal in need thereof a compound that mimics the interaction of the propeptide with the residues of the active site of 35 procathepsin K. Specifially, this compound comprises:

(i) an oxygen atom which interacts with a hydrogen atom donated by the indoie nitrogen of tryptophan 283 wherein the distance between these two atoms is 2.7-3.5~;
(ii) a hydrophobic group that interacts with tryptophan 283 wherein the distance between the centroid of said hydrophobic group and the centroid of the side chain atoms of tryptophan 283 is 4.10-7.10A;
(iii) a hydrophobic group that interacts with tyrosine 166 , methionine 167, alanine 233, leucine 259, and leucine 308, creating a hydrophobic pocket, and has distance ranges between the centroid of said hydrophobic group and the 1 o centroids of the side chain atoms of the amino acid residues of said hydrophobic pocket which are tyrosine 166: 4.91- 5.91, methionine 167: 5.74-6.74t~, alanine 233: 4.15-5.15, leucine 259: 6.18-7.18t~, and ieucine 308: 5.71-6.71; and (iv) an amino group with a pKa of less than 7 or an oxygen atom, each of which interacts with a hydrogen atom donated by the amide nitrogen of glycine wherein the distance between these two atoms is 2.7-3.SA. In particular, the preferred compound consists of a hydrophobic group that interacts with said hydrophobic pocket wherein said hydrophobic group is an isobutyl group.
The method of the instant invention comprises compounds characterized by the interactions of the atoms of the procathepsin K active site and the atoms of the propeptide in the region of the acive site according to Table IV.
This invention also includes a composition comprising procathepsin K in crystalline form wherein the procathepsin K in crystalline form is characterized by structure coordinates according to Table I. In particular, the composition has an active site cavity formed by the amino acids in Table IV wherein said active site is characterized by the distance between the atoms of Table II and the bond angles between interresidue atoms of Table III.
In another aspect of this invention is an isolated, properly folded procathepsin K molecule or fragment thereof having a conformation comprising a catalytically active site formed by the residues listed in Table IV, said active site defined by the protein coordinates of Table I and a peptide, peptidomimetic or synthetic molecule which binds with the active site cavity of procathepsin K.
Importantly, this invention provides for a method of identifying an inhibitor compound capable of binding to, and inhibiting the proteolytic activity of, cathepsin K, said method comprising:
introducing into a suitable computer program information defining an active site conformation of a procathepsin K molecule comprising a catalytically active site formed by the residues listed in Table IV, said active site defined by the protein coordinates of Table I, wherein said program displays the three-dimensional structure thereof;
creating a three dimensional representation of the active site cavityin said computer program;
displaying and superimposing the model of said test compound on the model of said active site;
assessing whether said test compound model fits spatially into the active site;
preparing said test compound that fits spatially into the active site;
using said test compound in a biological assay for a protease characterized by said active site; and determining whether said test compound inhibits cathepsin K activity in said assay.
This invention involves a method of drug design comprising using the ~ 5 structural coordinates of a procathepsin K crystal to computationally evaluate a chemical entity for associating with the active site of cathepsin K.
Alternately, this invention provides for a method of identifying inhibitors of cathepsin K said method comprising the steps of:
providing the coordinates of the atoms of the procathepsin K active site and the coordinates of the atoms of the propeptide in the region of the active site according to Table IV to a computerized modeling system, wherein said system displays the three-dimensional structure thereof;
displaying and superimposing a model of a test compound on the model of the propeptide;
assessing whether said test compound interacts with the active site of procathepsin K in a manner similar to that of the propeptide;
preparing said test compound that interacts with the active site of procathepsin K in a manner similar to that of the propeptide; and testing said test compound for cathepsin K inhibitory activity.
30 The three dimensional (3D) structure of the instant protease proenzyme reveals that human cathepsin K is highly homologous to other known cysteine proteinases of the papain family in the region of the mature enzyme. Cathepsin K is synthesized and secreted from the cell as an inactive proenzyme.
Autoproteolytic degradation of the N-terminal 99 amino acid pro-peptide produces the active, mature 35 form of cathepsin K. It is presumed that the activation of procathepsin K
in vivo occurs in the bone resorption pit which has a low pH environment. The instant invention provides for the crystal structure of human procathepsin K at 2.6 ~ngstroms resolution. Knowing the structure of procathepsin K provides a basis for the design of inhibitors of cathepsin K.
Listed in Figure 1 are the known amino acid sequences for the proenzymes of the papain superfamily of cysteine proteases: cathepsin K, cathepsin S, cathepsin L, actinidin, cathepsin H and cathepsin B, aligned to illustrate the homologies there between. According to the present invention the crystal structure of human procathepsin K has been determined at 2.6 angstroms. The structure was determined using the method of molecular replacement and refined to an Rc values of 0.204. Further refinement of the atomic coordinates will change the numbers in 10 Table I. Refinement of the crystal structure from another crystal form will result in a new set of coordinates, determination of the crystal structure of another cysteine protease will also result in different set of numbers for coordinates in Table I which has an experimental error of approximately 0.4 angstroms. Also, for example, the amino acid sequence of the cysteine proteases can be varied by mutation derivatization or by use of a different source of the protein.
Human procathepsin K contains 314 amino acids and the model of the enzyme provided herein is represented by residues S to 314. The first five amino acid residues are not well ordered in the structure.
The procathepsin K crystal structure reveals a conformation of the propeptide bound to the active site that is heretofor unknown and comprises a distinct three dimensional arrangement of atoms.
Table I discloses the protein coordinates of procathepsin K. These data are reported for the crystal structure described herein. The data are reported in Angstroms with reference to an orthogonal coordinate system in standard format, illustrating the atom, i.e., nitrogen, oxygen, carbon, sulfur (at oc,13, y, 8, or E, positions in the amino acid residues); the amino acid residue in which the atom is located with amino acid number, and the coordinates X, Y and Z in Angstroms (E1) from the crystal structure. Note that each atom in the active site and the entire structure has an unique position in the crystal. The data also report the B or 30 Temperature Factor values, which indicate the degree of thermal motion of the atom in root mean square displacement measurements (~2). Figure 1 illustrates the procathepsin K crystalline structure of the invention, including the active site.
The active site of procathepsin K and the propeptide is shown in Figure 2.
The pro-peptide of procathepsin K exhibits a globular domain formed by three 35 alpha-helices and one beta-strand which is located above the right domain of cathepsin K. An extended loop stretches from the globular domain through the active site and connects at the bottom of the mature cathepsin K. The RMS

WO 00/09653 PCT/US98/146;4 deviation between the CA atoms of the mature cathepsin K and the CA atoms of the refined proenzyme structure is only 0.46 ~ (215 CA pairs).
Residues 74 to 80 of the pro-peptide lie in the active site and are shown in Figure 2. The residues from cathepsin K which form contacts with the propeptide 5 are shown as a ball-and-stick model. The orientation of the propeptide in the active site cleft is opposite to that postulated for a natural substrate. The S' subsites (located above Cys 124 in Figure 2) are occupied by Met 75 (S2') and Thr 76 (S
1').
The S subsites are occupied by Gly 77 (S1), Leu 78 (S2) and Lys 79 (S3). The main chain atoms of the propeptide form numerous hydrogen bonds to mature cathepsin K
10 and are listed as follows: Lys 74 to Cys 121; Met 75 to Gln 118 and Trp 283; Gly 77 to Gly 165, and Lys 79 to Gly 165. The sidechains of the propeptide form extensive contacts with mature cathepsin K. The side chain of Met 75 is located in a hydrophobic area surrounded by side chains of Leu 63 and Met 66 from the propeptide and Trp 283 from mature cathepsin K. Thr 76 forms hydrogen bonds 15 from its sidechain hydroxyl group to mainchain carbonyls from residue Val 72 and Asn 260. Additionally, the side-chain methyl group of Thr 76 faces the hydrophobic cluster formed by residues Trp 283 and His 261. Gly 77 is located at the center of the active site within van der Waals radius of the catalytic cysteine. A
residue with a larger sidechain would not fit at this position. Leu 78 occupies the S2 active site 2o hydrophobic pocket, which is formed by Tyr 166, Met 167, Ala 233, Ala 262 and Leu 308. Lys 79 faces away from the catalytic site and forms a salt bridge with Asp 160.
The propeptide is anchored to the mature protein by hydrophobic interactions and hydrogen bonding. The hydrophobic face of helices 2 and 3, and a beta strand 25 pack against the apolar surface of mature cathepsin K (Figure 3). The beta strand from the propeptide hydrogen bonds with a betastrand from mature cathepsin K
forming an anti-parallel beta sheet. The following residues from helices 2 and 3 and the beta-strand; Tyr 41, Iie 42, His 45, Ala 49, His 54, Tyr 56, Leu 58, Met 60, His 62, Leu 63, Met 66, Val 71, Val 72 and Met 75, form hydrophobic contacts with side 3o chain atoms od mature cathepsin K. The apolar surface of the mature enzyme is formed by residues Ser 240, Phe 241, Phe 243, Tyr 244, Tyr 249, Tyr 250, His 261, Trp 283, Trp 287 and Met 295. Six of these sidechains, Phe 241, Tyr 244, Tyr 249, His 261, Trp 283, Trp 287 form an aromatic-aromatic stacking network. Near the active site a second region of apolar interactions exists. Residues Leu 78 and Val 35 80 pack against residues Tyr 166, Met 167, Ala 233 and Leu 308. A third region of hydrophobic interactions occurs near the C-terminus of the propeptide with residue His 84, Leu 91, Tyr 92 and Ile 93 packed against residue Tyr 209, Ile 212, Pro and Phe 311 (Figure 3).
Electrostatic interactions in the form of salt bridges are likely to play a significant role in the stabilization of the globular structure in the N-terminal domain of the propeptide. There are seven salt bridges within the pro-peptide. These are Asp 8 to Arg 32, Lys 20 to Asp 65, Asn 24 to Asp 27, Lys 25 to Glu 28, Arg 31 to Glu 70, Arg 32 to Glu 36 and Glu 48 to His 54. Asp 27 and Asp65 also form important hydrogen bonds to Asn 23 and Trp 14, respectively. Activation of the proenzyme occurs at low pH. Therefore disruption of these salt bridges at low pH
10 rnay disrupt the globular structure and lead to auto-activation of the proenzyme.
The crystal structure of procathepsin K of the present invention reveals the three dimensional structure of novel active. site interactions between the atoms of the amino acid residues of the mature and propeptide listed in Table IV.
This structure is clearly useful in the structure-based design of protease 15 inhibitors, which may be used as therapeutic agents against diseases in which inhibition of bone resorption is indicated. The discovery of the procathepsin K
catalytic site permits the design of potent, highly selective protease inhibitors.
Another aspect of this invention involves a method for identifying inhibitors of procathepsin K characterized by the crystal structure and novel active site 20 described herein. The novel protease crystal structure of the invention permits the identification of inhibitors of protease activity. Such inhibitors may bind to all or a portion of the active site of cathepsin K; or even be competitive or non-competitive inhibitors. Once identified and screened for biological activity, these inhibitors may be used therapeutically or prophylactically to block protease activity.
25 One design approach is to probe the cathepsin K of the invention with molecules composed of a variety of different chemical entities to determine optimal sites for interaction between candidate cathepsin K inhibitors and the enzyme.
For example, high resolution X-ray diffraction data collected from crystals saturated with solvent allows the determination of where each type of solvent molecule sticks.
30 Small molecules that bind tightly to those sites can then be designed and synthesized and tested for their cathepsin K inhibitor activity.
This invention also enables the development of compounds that can isomerize to short-lived reaction intermediates in the chemical reaction of a substrate or other compound that binds to or with cathepsin K. Thus, the time-dependent 35 analysis of structural changes in cathepsin K during its interaction with other molecules is permitted. The reaction intermediates of cathepsin K can also be deduced from the reaction product in co-complex with cathepsin K. Such information is useful to design improved analogues of known cysteine protease inhibitors or to design novel classes of inhibitors based on the reaction intermediates of the cathepsin K enzyme and cathepsin K inhibitor co-complex. This provides a novel route for designing cathepsin K inhibitors with both high specificity and stability.
Because cathepsin K may crystallize in more than one crystal form, the structure coordinates of procathepsin K, or portions thereof, as provided by this invention are particularly useful to solve the structure of those other crystal forms of cathepsin K. They may also be used to solve the structure of cathepsin K
mutants, 10 cathepsin K co-complexes, or of the crystalline form of any other protein with significant amino acid sequence homology to any functional domain of cathepsin K.
One method that may be employed for this purpose is molecular replacement. In this method, the unknown crystal structure, whether it is another crystal form of cathepsin K, a cathepsin K mutant, or a cathepsin K co-complex, or the crystal of some other protein with significant amino acid sequence homology to any functional domain of cathepsin K, may be determined using the procathepsin K
structure coordinates of this invention as provided in Table I. This method will provide an accurate structural form for the unknown crystal more quickly and efficiently than attempting to determine such information ab initio.
20 Thus, the procathepsin K structure provided herein permits the screening of known molecules and/or the designing of new molecules which bind to the protease structure, particularly at the active site, via the use of computerized evaluation systems. For example, computer modelling systems are available in which the sequence of the protease, and the protease structure {i.e., atomic coordinates of 25 procathepsin K and/or the atomic coordinate of the active site cavity, bond angles, dihedral angles, distances between atoms in the active site region, etc. as provided by Table I may be input. Thus, a machine readable medium may be encoded with data representing the coordinates of Table I in this process. The computer then generates structural details of the site into which a test compound should bind, 3o thereby enabling the determination of the complementary structural details of said test compound.
More particularly, the design of compounds that bind to or inhibit cathepsin K according to this invention generally involves consideration of two factors.
First, the compound must be capable of physically and structurally associating with 35 cathepsin K. Non-covalent molecular interactions important in the association of cathepsin K with its substrate include hydrogen bonding, van der Waals and hydrophobic interactions.

Second, the compound must be able to assume a conformation that allows it to associate with cathepsin K. Although certain portions of the compound will not directly participate in this association with cathepsin K, those portions may still influence the overall conformation of the molecule. This, in turn, may have a 5 significant impact on potency. Such conformational requirements include the overall three-dimensional structure and orientation of the chemical entity or compound in relation to all or a portion of the binding site, e.g., active site or accessory binding site of cathepsin K, or the spacing between functional groups of a compound comprising several chemical entities that directly interact with cathepsin 1o K.
The potential inhibitory or binding effect of a chemical compound with cathepsin K may be estimated prior to its actual synthesis and testing by the use of computer modelling techniques. If the theoretical structure of the given compound suggests insufficient interaction and association between it and cathepsin K, 15 synthesis and testing of the compound is obviated. However, if computer modelling indicates a strong interaction, the molecule may then be synthesized and tested for its ability to bind to cathepsin K in a suitable assay. In this manner, synthesis of inoperative compounds may be avoided.
An inhibitory or other binding compound of cathepsin K may be 2o computationally evaluated and designed by means of a series of steps in which chemical entities or fragments are screened and selected for their ability to associate with the individual binding pockets or other areas of cathepsin K.
One skilled in the art may use one of several methods to screen chemical entities or fragments for their ability to associate with cathepsin K and more 25 particularly with the individual binding pockets of the cathepsin K active site or accessory binding site. This process may begin by visual inspection of, for example, the active site on the computer screen based on the cathepsin K coordinates in Table I. Selected fragments or chemical entities may then be position cathepsin K.
Docking may be accomplished using software such as Quanta and Sybyl, followed 30 by energy minimization and molecular dynamics with standard molecular mechanics forcefields, such as CHARMM and AMBER.
Specialized computer programs may also assist in the process of selecting fragments or chemical entities. These include:

15 Once suitable chemical entities or fragments have been selected, they can be assembled into a single compound or inhibitor.

See, for example, the cathepsin K activity assay of Example 2 below. Other assay formats 30 may be used; these assay formats are nvt a limitation on the present invention.

5 The following examples illustrate various aspects of this invention. These examples do not limit the scope of this invention which is defined by the appended claims.
EXAMPLE 1: Analysis of the Structure of procathepsin K
A. Expression, Purification and Crystallization Plasmid constructions. Procathepsin K {procat K) was expressed using the PET system (Novagen). In order to express procat K, an existing clone containing the full-length human preprocathepsinK cDNA was subject to PCR
15 amplifcation using oligos designed to introduce a Met residue at amino acid 18 of the full-length preproenzyme. The resulting fragment was cleaved with NcoI and BamHI and this fragment was inserted into the pETl6b vector, resulting in pETprocat K.
Expression of recombinant, human procathensin K. Isolation and 2o solubilization of inclusion bodies. Recombinant pET vectors were transformed into strain BL21DE3 (Novagen). Bacteria were grown at 37C to OD600=0.6-0.7 and induced with 1mM IPTG for 2 hours. The cell pellet from 6 L of bacterial culture weighing 15 g was washed with 150 mL of 50 mM Tris/HCl, 5 mM EDTA, 150 mM
NaCI, pH 8Ø After centrifugation at 13,000 x g for 15 rains, the washed pellet was 25 resuspended into 150 mL of the same buffer prepared at 4~ C and lysed by passage twice through a cell disruptor (Avestin) at 10,000 psi. The lysate was centrifuged as above, the supernatant decanted and the pellet suspended in 150 mL 50 mM
Tris/HCI, 6 M guanidine HCI, 10 mM DTT, 5 mM EDTA, 150 mM NaCI, pH 8Ø
After stirring for 1 hr at room temperature, insoluble cellular debris was removed by 3o centrifugation at 23,000 x g for 30 rains and the supernatant clarified by filtration (0.45 um PVDF, Millipore). The resulting solution was assayed for protein concentration according to the method of Bradford using the BioRad protein asay and bovine serum albumin obtained from Pierce as standard.
Refolding and Purification. 645 mg of procathepsin K was refolded 35 by quick dilution of the denatured protein solution into 10 L of stirring, N2 (g) spraged 50 mM Tris/HCI, 5 mM EDTA, 10 mM reduced and 1 mM oxidized glutathione, 0.7 M L-arginine pH 8.0 prepared at room temperature. The solution was stirred overnight at 4° C then concentrated using tangential flow followed by a stirred cell (Amicon), both fitted with lOK membranes. The concentrate was clarified by centrifugation and filtration then dialyzed against 25 mM Na2P04, 1.0 M NaCI, pH 7.0 (buffer A). The 44 mL dialysate containing 343 mg of protein was applied at a LFR= 23 cmlhr in two runs to a 2.6 x 90 cm column of Superdex 75 (Pharmacia) pre-equilibrated in buffer A. Fractions containing procathepsin K
were identified and pooled based upon purity as observed on 15% acylamide SDS-PAGE
gels prepared according to the method of Laemmli (Laemmli U.K., {1970) Nature 227, 690-685). Rainbow high molecular weight markers (Amersham) were used as standards. Gels were visualized with 0.25% Brilliant Blue R stain (Sigma). A
portion of the 259 mg of protein recovered from the size exclusion columns was concentrated to 20 mg/mL using a centricon-10 then diluted 1:1 with 25 mM
Na2P04 pH 7.0 to yield a 10 mglmL solution in 25 mM , 0.5 M Na.CI, pH 7Ø
Crystals of procathepsin K grew to a size of approximately 0.3 mm3 in ten days at 4° C. The concentration of procathepsin K used in the crystallization was l0mglml. The hanging drops vapour diffusion method was used with a solution of 8-10% PEG6000, O.1M Na citrate at pH 5Ø X-ray diffraction data were measured from a single crystal using a Siemens two-dimensional position-sensitive detector.
Crystals of the complex are orthorhombic, space group C2221, with cell constants of a=56.81 ~, b=156.81 ~, and c=96.10 t~. The crystals contain one molecule in the asymmetric unit and contain 60% solvent.
B. Model Building and Refinement The structure of procathepsin K was solved by molecular replacement using the program XPLOR (Brunger, A. T., Kuriyan, J. and Karplus, M.
(1987) Science 235, 458-460). The coordinates for 217 residues from the structure of human cathespin K (Zhao, B. et al. ( 1977) Nature Struct. Biol. 4, 109-111 ) were used as a starting model. The cross rotation function was calculated using data from 10-3.5 t~ with a radius of integration of 23 ~ in a P 1 cell for the search model with dimensions of a=88.0 ~, b=74.0 ~, c=68.0 t~. The search was carried out with pseudo-orthogonal euler angles in Patterson space from 81 0-180°, 82 0-90, and 83 0-720°. The highest peak was 15.7 6. The translation search was computed using data from 10 -3.5 ~ and gave a peak at 26 6. The resulting model yielded a R-factor of 0.43. The R-factor for the model dropped to 0.40 after rigid body refinement from 10-3.5 ~ and to 0.31 after 200 cycles of positional refinement.
The electron density maps were improved using solvent flattening and by histogram matching as implemented in the module DM of the CCP4 suite of programs (Collaborative Computational Project, Number 4 (1994), "The CCP4 Suite: Programs for Protein Crystallography", Acta Cryst. D50, 760-763).
The modified electron density map was to build the model of used procathepsin K. Conventional positional refinement was used to refine the structure during model building. The structure was refined using X-plor. The final model of procathepsin K consists of residues 5 to 214. The simulated annealing refinement was finally carried out to a final R of 0.204. The backbone conformation of all residues is within the Ramachandran plot limits.
1 o EXAMPLE 2: Assavs Determination of cathepsin K proteolytic catalytic activity All assays for cathepsin K were carried out with human recombinant enzyme. Standard assay conditions for the determination of kinetic constants used a fluorogenic peptide substrate, typically Cbz-Phe-Arg-AMC, and were determined in 100 mM Na acetate at pH 5.5 containing 20 mM cysteine and 5 mM EDTA. Stock substrate solutions were prepared at concentrations of 10 or 20 mM in DMSO
with uM final substrate concentration in the assays. All assays contained 10% DMSO.
Independent experiments found that this level of DMSO had no effect on enzyme 20 activity or kinetic constants. All assays were conducted at ambient temperature.
Product fluorescence (excitation at 360 nM; emission at 460 nM) was monitored with a Perceptive Biosystems Cytofluor II fluorescent plate reader. Product progress curves were generated over 20 to 30 minutes following formation of AMC
product.
Inhibition studies Potential inhibitors were evaluated using the progress curve method. Assays were carried out in the presence of variable concentrations of test compound.
Reactions were initiated by addition of enzyme to buffered solutions of inhibitor and substrate. Data analysis was conducted according to one of two procedures depending on the appearance of the progress curves in the presence of inhibitors.
For those compounds whose progress curves were linear, apparent inhibition constants (Ki~app) were calculated according to equation 1 (Brandt et al., Biochemistry, 1989, 28, 140):
v = VyiA l ~Ka(1 + IIKi~ app) +AJ
(1) where v is the velocity of the reaction with maximal velocity Vm , A is the concentration of substrate with Michaelis constant of Ka, and I is the concentration of inhibitor.
For those compounds whose progress curves showed downward curvature characteristic of time-dependent inhibition, the data from individual sets was analyzed to give kobs according to equation 2:
[AMC) = vss t + w0 - vss) h - exP (-kobst)~ ~ kobs (2) where [AMC] is the concentration of product formed over time t, vp is the initial reaction velocity and vss is the final steady state rate. Values for kobs were then analyzed as a linear function of inhibitor concentration to generate an apparent second order rate constant (kobs / inhibitor concentration or kobs / [I)) describing the time-dependent inhibition. A complete discussion of this kinetic treatment has been fully described (Morrison et al., Adv. Enzymol. Relat. Areas Mol. Biol., 19$8, 61, 201).
This assay measures the affinity of inhibitors to cathepsin K. One skilled in the art would consider any compound exhibiting a K; value of less than 50 micromolar to be a potential lead compound for further research.
Human Osteoclast Resorption Assay Aliquots of osteoclastoma-derived cell suspensions were removed from liquid nitrogen storage, warmed rapidly at 37°C and washed x 1 in RPMI-medium by centrifugation ( 1000 rpm, 5 min at 4°C). The medium was aspirated and replaced with murine anti-HLA-DR antibody, diluted 1:3 in RPMI-1640 medium, and incubated for 30 min on ice The cell suspension was mixed frequently.
The cells were washed x2 with cold RPMI-1640 by centrifugation (1000 rpm, 5 min at 4°C) and then transferred to a sterile 15 rnL centrifuge tube. The number of mononuclear cells were enumerated in an improved Neubauer counting chamber.
Sufficient magnetic beads (5 / mononuclear cell), coated with goat anti-mouse IgG, were removed from their stock bottle and placed into 5 mL of fresh medium (this washes away the toxic azide preservative). The medium was removed by immobilizing the beads on a magnet and is replaced with fresh medium.
The beads were mixed with the cells and the suspension was incubated for 30 min on ice. The suspension was mixed frequently. The bead-coated cells were immobilized on a magnet and the remaining cells (osteoclast-rich fraction) were decanted into a sterile 50 mL centrifuge tube. Fresh medium was added to the bead-coated cells to dislodge any trapped osteoclasts. This wash process was repeated x10. The bead-coated cells were discarded.
The osteoclasts were enumerated in a counting chamber, using a large-bore disposable plastic Pasteur pipette to charge the chamber with the sample. The cells were pelleted by centrifugation and the density of osteoclasts adjusted to l.Sx104/mL in EMEM medium, supplemented with 10% fetal calf serum and l.7glliter of sodium bicarbonate. 3 mL aliquots of the cell suspension ( per treatment) were decanted into 15 mL centrifuge tubes. These cells were pelleted by 1 o centrifugation. To each tube 3 mL, of the appropriate treatment was added (diluted to 50 uM in the EMEM medium). Also included were appropriate vehicle controls, a positive control (87MEMi diluted to 100 ug/mL) and an isotype control (IgG2a diluted to 100 ug/mL). The tubes were incubate at 37°C for 30 min.
0.5 mL aliquots of the cells were seeded onto sterile dentine slices in a 48-well plate and incubated at 37°C for 2 h. Each treatment was screened in quadruplicate. The slices were washed in six changes of warm PBS ( 10 mL /
well in a 6-well plate) and then placed into fresh treatment or control and incubated at 37°C
for 48 h. The slices were then washed in phosphate buffered saline and fixed in 2%
glutaraldehyde (in 0.2M sodium cacodylate) for 5 min., following which they were washed in water and incubated in buffer for 5 min at 37°C. The slices were then washed in cold water and incubated in cold acetate buffer / fast red garnet for 5 min at 4°C. Excess buffer was aspirated, and the slices were air dried following a wash in water.
The TRAP positive osteoclasts were enumerated by bright-field microscopy and were then removed from the surface of the dentine by sonication. Pit volumes were determined using the Nikon/Lasertec ILM21W confocal microscope.
EXAMPLE 3: Method of Detecting Inhibitors The three dimensional atomic structure can be readily used as a template for selecting potent inhibitors. Various computer programs and databases are available for the purpose. A good inhibitor should at least have excellent steric and electrostatic complementarity to the target,. a fair amount of hydrophobic surface buried and sufficent conformational rigidity to minimize entropy loss upon binding.
The approach usually comprises several steps:
1 ) Define a region to target. the active site cavity of procathepsin K can be selected, but any place that is essential to the protease activity could become a WO 00109b53 PCT/US98114634 potential target. Since the crystal structure has Been determined, the spatial and chemical properties of the target region is known.
2) Docking a small molecule onto the target. Many methods can be used to archive this. Computer databases of three-dimensional structures are available for screening millions of small molecular compounds. A negative image of these compounds can be calculated and used to match the shape of the target cavity. The profiles of hydrogen bond donor-acceptor and lipophilic points of these compounds can also be used to complement those of the target. Anyone skilled in the art would be able to indentify many small molecules or fragments as hits.
3) Linking and extending recognzition fragments. Using the hits identified by above procedure, one can incorporate different functional groups or small molecules into a single, larger molecule. The resulting molecule is likely to be more potent and have higher specificity. It is also possible to try to improve the "seed" inhibitor by adding more atoms or fragments that will interact with the target protein. The originally defined target region can be readily expanded to allow further necessary extension.
A limited numer of promising compounds can be selected through the process. They can then be synthesized and assayed for their inhibitory properties.
The success rate can sometimes be as high as 20%, and it may still be higher with the rapid progresses in computing methods.
