BACKGROUND OF THE INVENTION [002] The following description of the background of the invention is provided to aid in the understanding the invention, but is not admitted to be or describe prior art to the invention.

[003] NF-KB is a ubiquitous transcription factor that plays a prominent role in the activation of the immune system and in stress responses by regulating the transcription of many early, inducible genes including proinflammatory cytokines, adhesion molecules, growth factors, enzymes, and receptors (Ghosh S. , May, M. J. , and Kopp. E (1998) Annu. Rev. Immunol. 16,115-260 ; Zandi, E. , and Karin, M. (1999) Mol. Cell. Biol. 19, 4547-4551 ; Karin, M. (1999) J.

Biol. Chem. 274,27339-27342). Specificity of gene expression is determined at a cellular level by a diverse array of external stimuli such as bacterial products including LPS, as well as cytokines, most importantly tumor necrosis factor-a (TNFa) and interleukin- (ILIp). Through the synergistic interaction with other transcription factors, further specificity can be achieved while maintaining enormous potential to coordinately induce a large number of functionally related

genes. NF-KB is composed of homo and heterodimers of the Rel protein family and is sequestered in an inactive form in the cytoplasm by members of the IKB family of inhibitory proteins (Ghosh S. , May, M. J. , and Kopp. E (1998) Annu.

Rev. Immunol. 16,115-260 ; Zandi, E. , and Karin, M. (1999) Mol. Cell. Biol. 19, 4547-4551 ; Karin, M. (1999) J. Biol. Chem. 274,27339-27342). IKBs mask the nuclear localization signal on NF-KB, preventing nuclear translocation and hence DNA binding to the promoter regions of responsive genes. Stimulation of cells with an agonist that activates NF-KB leads to a series of biochemical signals, ultimately resulting in the phosphorylation, ubiquitinylation, and degradation of IKBs, thereby releasing NF-xB for nuclear translocation (Ghosh S. , May, M. J. , and Kopp. E (1998) Annu. Rev. Immunol. 16,115-260 ; Zandi, E. , and Karin, M. (1999) Mol. Cell. Biol. 19,4547-4551 ; Karin, M. (1999) J.

Biol. Chem. 274,27339-27342). Recently, two IoB kinases (IKK1 or IKKa and IKK2 or IKKß), which phosphorylate IrBs and thereby initiate their degradation, have been cloned and characterized by a number of laboratories (Ghosh S. , May, M. J. , and Kopp. E (1998) Annu. Rev. Immunol. 16,115-260 ; Zandi, E. , and Karin, M. (1999) Mol. Cell. Biol. 19, 4547-4551 ; Karin, M.

(1999) J. Biol. Chem. 274,27339-27342). The catalytic subunits, IKK1 and IKK2, are similar structurally as well as enzymatically and exist as a heterodimer in a large protein complex referred to as the IKK signalsome (Regnier, C. , Song, H. , Gao, X. , Goeddel, D. , Cao, Z. and Rothe, M. (1997) Cell 90,373-383 ; DiDonato, J. A. , Hayakawa, M. , Rothwarf, D. M. , Zandi, E. and Karin, M. (1997) Nature 388,548-554 ; Mercurio, F. , Zhu, H. , Murray, B. W., Shevchenko, A. , Bennett, B.

A third protein, NEMO (IKKy, IKKAP1), is a regulatory adapter protein necessary for IKK activation and kinase activity (Yamaoka, S. , Courtois, G. , Bessia, C. , Whiteside, S. T., Weil, R. , Agou, F., Kirk, H. E. , Kay, R. J. , and Ireal, A. (1998) Cell 93, 1231-1240; Rothwarf, D. M. , Zandi, E.,

M. (1999) Mol. Cell. Biol. 2,1526- 1538). IKK1 and IKK2 are co-expressed in most human adult tissues as well as in different developmental stages of mouse embryos (Regnier, C. , Song, H., Gao, X. , Goeddel, D. , Cao, Z. and Rothe, M. (1997) Cell 90, 373-383; DiDonato, J. A. , Hayakawa, M. , Rothwarf, D. M. , Zandi, E. and Karin, M. (1997) Nature 388,548-554 ; Mercurio, F. , Zhu, H. , Murray, B. W. , Shevchenko, A., Bennett, B.

T. , and Wang, Y. (1998) Gene 222,31-40). This kinase complex appears to represent a critical, common denominator in the activation of NF-KB in a number of signal transduction pathways stimulated by a variety of agonists including cytokines, such as TNFa and IL1 (3, microbial products such as LPS and viral proteins such as TAX, as well as phorbol esters, oxidizing agents and serine/tyrosine phosphatases (Ghosh S. , May, M. J. , and Kopp. E (1998) Annu.

Rev. Immunol. 16,115-260 ; Zandi, E. , and Karin, M. (1999) Mol. Cell. Biol. 19, 4547-4551 ; Karin, M. (1999) J. Biol. Chem. 274,27339-27342).

[004] IKK1 (also termed IKKa, Regnier, C. , Song, H. , Gao, X. , Goeddel, D., Cao, Z. and Rothe, M. (1997) Cell 90,373-383 ; DiDonato, J. A. , Hayakawa, M., Rothwarf, D. M. , Zandi, E. and Karin, M. (1997) Nature 388,548-554 ; Mercurio, F., Zhu, H. , Murray, B. W. , Shevchenko, A. , Bennett, B. L. , Li, J. W., Young, D. B. , Barbosa, M. , Mann, M. , Manning, A. And Roa, A. (1997) Science 278,860-866) was cloned simultaneously by standard biochemical purification of the IKB kinase activity from TNFa stimulated HeLa S3 cells and by its interaction with the MAP3K, NF-KB inducing kinase (NIK), in a yeast two- hybrid screen. IKK1 was identified as the previously cloned serine-threonine kinase, CHUK (Connelly, M. and Marcu, K. (1995) Cell. Mol. Biol. Res. 41,

537-549). IKK1 (also termed IKKa) is an 85 kDa, 745 amino acid protein that contains an N-terminal serine/threonine kinase catalytic domain, a leucine zipper-like amphipathic helix, and a C-terminal helix-loop-helix domain. IKK2 (also termed IKKp) was also cloned by standard biochemical purification, copurifying with IKK1 from TNFa stimulated HeLa S3 cells as well as by being identified in the public database from an EST clone with sequence homology to IKK1 (Mercurio, F. , Zhu, H. , Murray, B. W. , Shevchenko, A. , Bennett, B. L. , Li, J. W. , Young, D. B. , Barbosa, M. , Mann, M. , Manning, A. and Roa, A. (1997) Science 278,860-866 ; Zandi, E. Rothwarf, D. M. , Delhase, M. , Hayadawa, M and Karin, M. (1997) Cell 91,243-252 ; Woronicz, J. D. , Gao, X. , Cao, Z., Rothe, M. And Goeddel, D. V. (1997) Science 278, 866-869). IKK2 is an 87 kDa, 756 amino acid protein with the same over all topology as IKK1 except for the addition of an 11 amino acid extension at the C-terminus. IKK1 and IKK2 are 52% identical overall with 65% identity in the kinase domain and 44% identity in the protein interaction domains in the C-terminus. Data obtained using transient mammalian expression analysis, by in vitro translation experiments and by coexpression in a baculoviral system reveals that IKK1 and IKK2 associate preferentially as a heterodimer through their leucine zipper motifs. Although homodimers have also been described in these systems, the heterodimer is thought to be the physiologic form of the kinase in mammalian cells (Zandi, E. Rothwarf, D. M. , Delhase, M. , Hayadawa, M and Karin, M.

(1997) Cell 91, 243-252; Li, J. , Peet, G. W., Pullen, S. S. , Schembri-King, J., Warren, T. C. , Marcu, K. B. , Kehry, M. R. , Barton, R. and Jakes, S. (1998) J.

Biol. Chem. 273,30736-30741). Finally, NEMO (also termed IKKy) contains three a-helical regions including a leucine zipper, interacts preferentially with IKK2 and is required for activation of the heterodimeric kinase complex perhaps by bringing other proteins into the signalsome complex (Yamaoka, S. , Courtois, G. , Bessia, C. , Whiteside, S. T., Weil, R. , Agou, F. , Kirk, H. E. , Kay, R. J. , and Ireal, A. (1998) Cell 93,1231-1240 ; Rothwarf, D. M. , Zandi, E., Natoli, G. , Karin, M. (1998) Nature 395,297 ; Mercurio, F. , Murray, B. W. , Shevchenko, A. , Bennet, B. L. , Young, D. B. , Li, J. W. , Pascual, G., Motiwala, A. , Zhu, H.,

Mann, M and Manning, A. M. (1999) Mol. Cell. Biol. 2,1526-1538).

[005] The kinase activities of IKK1 and IKK2 are regulated by phosphorylation and require an intact leucine zipper (LZ) for dimerization as well as an intact helix-loop-helix (HLH) domain, which can exert a positive regulatory effect on kinase activity even when it is expressed in trans with the remainder of the IKK protein (Regnier, C. , Song, H. , Gao, X. , Goeddel, D. , Cao, Z. and Rothe, M. (1997) Cell 90,373-383 ; DiDonato, J. A. , Hayakawa, M., Rothwarf, D. M. , Zandi, E. and Karin, M. (1997) Nature 388,548-554 ; Mercurio, F., Zhu, H. , Murray, B. W. , Shevchenko, A. , Bennett, B. L. , Li, J. W., Young, D. B. , Barbosa, M. , Mann, M. , Manning, A. and Roa, A. (1997) Science 278,860-866 ; Zandi, E. Rothwarf, D. M., Delhase, M. , Hayadawa, M and Karin, M. (1997) Cell 91, 243-252; Woronicz, J. D. , Gao, X. , Cao, Z. , Rothe, M. and Goeddel, D. V. (1997) Science 278, 866-869; Dehase, M. , Hayakawa, M. , Chen, Y. , and Karin, M. (1999) Science 284,309-313). Both IKK subunits contain a canonical MAPKK activation loop motif near the N-terminus which is the target for phosphorylation and activation of kinase activity by MAP3Ks such as NIK and MEKK1, although the physiologic regulation by these two upstream kinases awaits further characterization (Zandi, E. , and Karin, M. (1999) Mol.

Cell. Biol. 19,4547-4551 ; Karin, M. (1999) J. Biol. Chem. 274,27339-27342 ; Karin, M. , and Delhase, M. (1998) Proc. Natl. Acad. Sci. USA 95,9067-9069).

Finally, phosphorylation of serines in the C-terminus of IKK2 results in a decrease in IKK activity and it is postulated to be responsible for the transient kinase activity seen after stimulation of cells with an agonist (Dehase, M. , Hayakawa, M. , Chen, Y. , and Karin, M. (1999) Science 284,309-313).

[006] IKK2 demonstrates a more potent kinase activity compared to IKK1 using IoBa or IKBP as a substrate (Mercurio, F. , Zhu, H. , Murray, B. W., Shevchenko, A. , Bennett, B. L. , Li, J. W. , Young, D. B. , Barbosa, M. , Mann, M., Manning, A. and Roa, A. (1997) Science 278,860-866 ; Zandi, E. Rothwarf, D. M. , Delhase, M. , Hayadawa, M and Karin, M. (1997) Cell 91, 243-252;

Woronicz, J. D. , Gao, X. , Cao, Z. , Rothe, M. and Goeddel, D. V. (1997) Science 278,866-869 ; Dehase, M. , Hayakawa, M. , Chen, Y. , and Karin, M. (1999) Science 284,309-313). Mutations of the phospho-acceptor serine residues within the MAPKK activation loop alters IKK2 kinase activity; the serine to alanine substitutions result in decreased kinase activity whereas the serine to glutamic acid substitutions result in a constitutively active kinase. Similar alanine mutations in IKK1 do not result in a decreased stimulation of total IKK activity in response to TNFa or IL1 (3 (Dehase, M. , Hayakawa, M. , Chen, Y. , and Karin, M. (1999) Science 284,309-313). IKK2 being the dominant kinase activity within the IKK complex is further supported by the analysis of fibroblasts from mice deficient in IKK1 or IKK2. Fibroblasts lacking IKK1 retain full IKK activity in response to cytokines and could activate NF-KB. In contrast, fibroblasts lacking IKK2 do not exhibit IKK activity when stimulated with cytokines nor do they activate NF-KB. Furthermore, the phenotypes of each IKK knock out is unique with IKK1 deficiency resulting in skin and skeletal defects and IKK2 knock out being embryonic lethal due to hepatocyte apoptosis (Li, Q. , Antwerp, D. V., Mercurio, F. , Lee, K. , and Verma, 1. M.

[007] It is well-known that NF-KB plays a key role in the regulated expression of a large number of pro-inflammatory mediators including cytokines such as IL-6 and IL-8, cell adhesion molecules, such as ICAM and VCAM, and inducible nitric oxide synthase (iNOS). Such mediators are known to play a role in the recruitment of leukocytes at sites of inflammation and in the case of

iNOS, may lead to organ destruction in some inflammatory and autoimmune diseases. The importance of NF-KB in inflammatory disorders is further strengthened by studies of airway inflammation including asthma in which NF- KB has been shown to be activated. This activation may underlie the increased cytokine production and leukocyte infiltration characteristic of these disorders.

In addition, inhaled steroids are known to reduce airway hyper responsiveness and suppress the inflammatory response in asthmatic airways. In light of the recent findings with regard to glucocorticoid inhibition of NF-KB, one may speculate that these effects are mediated through an inhibition of NF-KB.

Further evidence for a role of NF-KB in inflammatory disorders comes from studies of rheumatoid synovium. Although NF-KB is normally present as an inactive cytoplasmic complex, recent immunohistochemical studies have indicated that NF-KB is present in the nuclei, and hence active, in the cells comprising rheumatoid synovium. Furthermore, NF-KB has been shown to be activated in human synovial cells in response to stimulation with TNF-a. Such a distribution may be the underlying mechanism for the increased cytokine and eicosanoid production characteristic of this tissue. See Roshak, A. K. , et al. , J.

Biol. Chem. , 271,31496-31501 (1996). The NF-KB/Rel and IxB proteins are also likely to play a key role in neoplastic transformation. Family members are associated with cell transformation in vitro and in vivo because of overexpression, gene amplification, gene rearrangements, or translocations. In addition, rearrangement and/or amplification of the genes encoding these proteins are seen in 20-25% of certain human lymphoid tumors. In addition, a role for NF-KB in the regulation of apoptosis has been reported strengthening the role of this transcription factor in the control of cell proliferation.

[008] The NF-KB/Rel and IoB proteins are also likely to play a key role in neoplastic transformation. Family members are associated with cell transformation in vitro and in vivo because of overexpression, gene amplification, gene rearrangements, or translocations (Gilmore TD, Trends Genet 7: 318-322,1991 ; Gillmore TD, Oncogene 18: 6925-6937,1999 ; Rayet B.

et al., Oncogene 18: 6938-6947,1991). In addition, rearrangement and/or amplification of the genes encoding these proteins are seen in 20-25% of certain human lymphoid tumors. In addition, a role for NF-1cB in the regulation of apoptosis, cell cycle progression, invasion, and metastasis has been reported (Bours V. et al., Biochemical Pharmacology 60: 1085-1090,2000) strengthening the role of this transcription factor in the control of cell proliferation. The inhibition of NIF-KOB has been shown to potentiate TNF-and cancer therapy through increased apoptosis (Wang C-Y et al., Science 274: 784-787,1996 ; Wang C-Y et al., Nat Med 5: 412-417,1999). It has also been shown that human T-cell leukemia virus type 1 (HTLV1) infected cells (the etiological agent of an aggressive malignancy of activated CD4+ T Iymphocytes), IKKct and IKKß are expressed constitutively, which normally function in a transient manner (Chu Z- L et al., J of Biological Chemistry 273: 15891-15894,1998). The HTLV1 transforming and transactivating protein (Tax) has been shown to bind MEKK1 and increases the activity of IKKß to enhance phosphorylation of serine residues in IKB (X that lead to its degradation.

All of these salts may be prepared by conventional means from the corresponding compound of the present invention by reacting, for example, the appropriate acid or base with the compound of the present invention.

[0022] Also embraced within this invention are pharmaceutical compositions comprising one or more compounds of the present invention in association with one or more non-toxic, pharmaceutically acceptable carriers and/or diluents and/or adjuvants and/or excipient (collectively referred to herein as"carrier" materials) and, if desired, other active ingredients. Accordingly, the compounds of the present invention may be used in the manufacture of a medicament.

Pharmaceutical compositions of the compounds of the present invention prepared as herein before described may be formulated as solutions or lyophilized powders for parenteral administration. Powders may be reconstituted by addition of a suitable diluent or other pharmaceutically acceptable carrier prior to use. The liquid formulation may be a buffered, isotonic aqueous solution. The compounds of the present invention may be administered by any suitable route, preferably in the form of a pharmaceutical composition adapted to such a route, and in a dose effective for the treatment intended. The compounds and composition may, for example, be administered intravascularly, intraperitoneally, intravenously, subcutaneously, intramuscularly, intramedullary, orally, or topically. For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension, or liquid. The active ingredient may also be administered

by injection as a composition wherein, for example, normal isotonic saline solution, standard 5% dextrose in water or buffered sodium or ammonium acetate solution may be used as a suitable carrier. Such formulation is especially suitable for parenteral administration, but may also be used for oral administration or contained in a metered dose inhaler or nebulizer for insufflation. It may be desirable to add excipients such as polyvinylpyrrolidone, gelatin, hydroxy cellulose, acacia, polyethylene glycol, mannitol, sodium chloride, or sodium citrate. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are tablets or capsules. The amount of therapeutically active compound that is administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex and medical condition of the subject, the severity of the disease, the route and frequency of administration, and the particular compound employed, and thus may vary widely. The pharmaceutical compositions may contain active ingredient in the range of about 0.1 to 2000 mg, preferably in the range of about 0.5 to 500 mg and most preferably between about 1 and 100 mg. A daily dose of about 0.01 to 100 mg/kg bodyweight, preferably between about 0.1 and about 50 mg/kg body weight and most preferably between about 1 to 20 mg/kg bodyweight, may be appropriate. The daily dose can be administered in one to four doses per day. For therapeutic purposes, the compounds of this invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered orally, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled release formulation as may be provided in a dispersion of active compound in a sustained release material such as glyceryl monostearate,

glyceryl distearate, hydroxypropylmethyl cellulose alone or with a wax.

Formulations for parenteral administration may be in the form of aqueous or non-aqueous isotonic sterile injection solutions or suspensions. These solutions and suspensions may be prepared from sterile powders or granules having one or more of the carriers or diluents mentioned for use in the formulations for oral administration. The compounds may be dissolved in water, polyethylene glycol, propylene glycol, ethanol, corn oil, cottonseed oil, peanut oil, sesame oil, benzyl alcohol, sodium chloride, and/or various buffers. The pharmaceutical preparations are made following the conventional techniques of pharmacy involving milling, mixing, granulating, and compressing, when necessary, for tablet forms ; or milling, mixing and filling for hard gelatin capsule forms. When a liquid carrier is used, the preparation will be in the form of a syrup, elixir, emulsion, or an aqueous or non-aqueous suspension. Such a liquid formulation may be administered orally or filled into a soft gelatin capsule. For rectal administration, the compounds of the present invention may also be combined with excipients such as cocoa butter, glycerin, gelatin, or polyethylene glycols and molded into a suppository. The methods of the present invention include topical administration of the compounds of the present invention. By topical administration is meant non-systemic administration, including the application of a compound of the invention externally to the epidermis, to the buccal cavity and instillation of such a compound into the ear, eye, and nose, wherein the compound does not significantly enter the blood stream. By systemic administration is meant oral, intravenous, intraperitoneal, and intramuscular administration. The amount of a compound of the present invention (hereinafter referred to as the active ingredient) required for therapeutic or prophylactic effect upon topical administration will, of course, vary with the compound chosen, the nature and severity of the condition being treated and the animal undergoing treatment, and is ultimately at the discretion of the physician.

[0023] The topical formulations of the present invention, both for veterinary and for human medical use, comprise an active ingredient together with one or

more acceptable carriers therefore, and optionally any other therapeutic ingredients. The carrier must be"acceptable"in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. Formulations suitable for topical administration include liquid or semi- liquid preparations suitable for penetration through the skin to the site of where treatment is required such as: liniments, lotions, creams, ointments or pastes, and drops suitable for administration to the eye, ear or nose. The active ingredient may comprise, for topical administration, from 0.01 to 5.0 wt%. of the formulation.

Other adjuvants and modes of administration are well and widely known in the pharmaceutical art. Although this invention has been described with respect to specific embodiments, the details of these embodiments are not to be construed as limitations.

[0026] Another aspect of the present invention is chemical intermediates useful in the synthesis of the compounds of Formula I and II.

[0027] Another aspect of the present invention is methods of syntheses of the compounds of Formula I and II.

GENERAL SYNTHETIC PROCEDURES [0028] The starting materials used herein are commercially available or are prepared by routine methods well known to those of ordinary skill in the art and can be found in standard reference books, such as the COMPENDIUM OF ORGANIC SYNTHETIC METHODS, Vol. I-VI (published by Wiley- Interscience).

[0029] The compounds of the invention can be synthesized according to the following procedures of Schemes I-X, wherein the R1-R16 substituents, linker A, are as defined for Formula I and lI, above, except where further noted.

[0030] SCHEME I Synthetic Scheme I illustrates the procedure used to prepare the antiinflammatory pyrazoles of the present invention. 1,3-Dicarbonyl compounds such as 1, or the shown enol form which is in equilibrium with the 1,3-diketone, are allowed to react with a substituted hydrazine hydrochloride 2 in warm methanol or ethanol or acetic acid to provide the pyrazoles 3 via a condensation reaction. When A =-CH2CH2-, the central ring may be aromatized to provide A =-CH=CH-, by using an oxidant such as DDQ, Pd or Pt on carbon with cyclooctadiene or other H2 acceptor, or sulfur in an appropriate solvent.

[0031] SCHEME II

Synthetic Scheme II illustrates the procedure for the preparation of substituted diketones 1. An appropriately substituted ketone 4, including, but not limited to; 1-indanones, 1-tetralones, and 1-benzosuberones, is first treated with base, such as sodium methoxide, lithium bistrimethylsilylamide or lithium diisopropylamide (LDA), followed by condensation with a suitable acylating agent, such as, dimethyl or diethyl oxalate, in an appropriate solvent, such as methanol, diethyl ether or tetrahydrofuran, to provide 1,3-dicarbonyl compounds 1 which are suitable for conversion into antiinflammatory pyrazoles as illustrated in Scheme I. Alternatively, the dicarbonyl compounds 1 can be directly prepared from commercially available cyclic ketones 4.

[0032] SCHEME III Synthetic Scheme III illustrates a three-step procedure used for the preparation of substituted 1-tetralones. In step one, an appropriate substituted benzene 5 is condensed with succinic anhydride and a catalyst such as aluminum chloride into the corresponding 4-phenyl-4-ketobutanoic acid derivatives 6. In step two, the keto group of the 4-phenyl-4-ketobutanoic acids 6 is reduced using catalytic hydrogenation or Wolff-Kishner type reductions, thus providing 4-

phenylbutanoic acids 7. In addition, ketone reductions can be carried out using metal amalgams. In step three, the 4-phenylbutanoic acids are treated with a mixture of trifluoroacetic anhydride, and trifluoroacetic acid to effect intramolecular Friedel-Crafts acylation affording selected tetralones 8.

Alternatively, the Friedel-Crafts acylation can be affected with other strong acids such as polyphosphoric acid, sulfuric acid or aluminum chloride.

[0033] SCHEME IV Synthetic Scheme IV describes an alternate synthetic route to 1-tetralones 8. In step one, addition of allylmagnesium bromide in a suitable solvent such as, THF or diethyl ether, to an appropriately substituted benzoate 9 affords the 1- phenylbut-3-ene-l-ones 10. In step two, the 1-phenylbut-3-ene-1-ones 10 can be cyclized under Friedel-Crafts alkylation conditions, provided R4 is a ring activating substituent, using catalysts such as aluminum chloride to produce 1- tetralones 8.

[0034] SCHEME V Scheme V describes the direct modification of 1-tetralone to substituted tetralones. Commercially available 1-tetralone may be treated with a variety of

electrophilic reagents such as bromine, ammonium nitrite or vinylsilanes, represented by E+, with or without a catalyst to generate directly a substituted tetralone 8, containing bromo, nitro or vinyl groups. Such tetralones 8 can be further embellished to provide the desired substitution patterns. Mixtures may be readily separated using chromatographic techniques.

[0035] SCHEME VI An alternate to Scheme V is Scheme VI wherein an appropriately substituted decaline is subjected to electrophilic addition to generate substituted decalins 11. Substituted decalins may also be prepared by Friedel-Crafts alkylation of substituted benzenes. Substituted decalins 11 can then be oxidized to the tetralones 8 using oxidants such as KMn04 or Se02.

[0036] SCHEME VII Scheme VII describes the modification of existing tetralones into analogs containing differing functional groups that can also be further modified. By example, hydroxy tetralone (8a where R4 = OH) can be converted to the triflate 8b by treatment with trifluoromethane sulfonic anhydride. Triflate 8b can the be subjected to Pd (OAc) 2 an appropriate phosphine and CO in the presence of methanol to generate tetralone 12 containing a carboxy methyl group. Triflates

can be used in a variety of palladium coupling reactions to introduce additional functional groups.

[0037] SCHEME Vm Synthetic Scheme VIM illustrates a three step procedure used for the preparation of substituted 1-indanones 16. In step one, an appropriate substituted benzaldehyde 13 is condensed with methyl acetate and a catalyst such as triethylamine into the corresponding methyl cinnamate derivatives 14.

Additionally, commercially available cinnamates may be used in the following steps. In step two the olefin group of the cinnamate 14 is reduced using catalytic hydrogenation and the ester hydrolyzed with base, such as NaOH, thus providing 3-phenylpropanoic acids 15. In step three, the 3-phenylpropanoic acids are treated with a mixture of trifluoroacetic anhydride and trifluoroacetic acid to effect intramolecular Friedel-Crafts acylation affording selected 1- indanones 16. Alternatively, the Friedel-Crafts acylation can be effected with other strong acids such as sulfuric acid or aluminum chloride.

[0038] SCHEME EX

Synthetic Scheme IX illustrates a two-step route for the preparation of substituted 1-indanones 16. Commercially available methyl benzoates 9, or other alkyl esters, may be treated with a vinyl lithium reagent to afford phenylvinyl ketones 17. Alternatively, dimethylamides or N-methyl-O- methylhydroxamides may be used in place of the esters. Also, other vinyl metals, such as; vinylmagnesium bromide may be used in place of the vinyl lithium reagent. The resulting phenylvinyl ketones may be cyclized using Friedel-Crafts alkylating catalysts, such as aluminum chloride.

[0039] SCHEME X Synthetic Scheme X illustrates a three step procedure used for the preparation of substituted 1-benzosuberones 20. In step one, an appropriate substituted benzene 5 is condensed with glutaric anhydride and a catalyst such as aluminum chloride into the corresponding 5-phenyl-5-ketopentanoic acid derivatives 18.

In step two, the keto group of the 5-phenyl-5-ketopentanoic acids 18 is reduced

using catalytic hydrogenation or Wolff-Kishner type reductions, thus providing 5-phenylpentanoic acids 19. In addition, ketone reductions can also be carried out using metal amalgams. In step three, the 5-phenylpentanoic acids are treated with a mixture of trifluoroacetic anhydride, and trifluoroacetic acid to effect intramolecular Friedel-Crafts acylation affording selected benzosuberones 20.

Alternatively, the Friedel-Crafts acylation can be affected with other strong acids such as polyphosphoric acid, H2SO4 or AlCl3. Alternatively, 5-phenyl-5- ketopentanoic acids 18, can be prepared from glutaric acid and a phenyllithium or a phenyl Grignard reagent appropriately substituted and compatible with reaction conditions.

Scheme XI describes the general synthesis of pyrazolo [4,3-c] quinoline analogs of this present invention. In step 1, aniline was heated with acrylic acid in a solvent such toluene to give N-phenyl-ß-aniline. In step two, the acid was treated with PPA at 100°C to give dihydroquinolinone. In step three, the ketone was first treated with a base such as LiHMDS, followed by diethyl oxylate to afford the intermediate. This intermediate was then reacted with a substituted phenylhydrazine to form pyrazole in step four; substituents can be sulfonamide and sulfone (aromatization occurred in this reaction presumably by ß- elimination). In step five; the aromatized pyrazole was converted to amide by using ammonia in ethanol.

The sulfonamides, amides, and urea were synthesized in a library format by using a Bohdan reaction block. The starting materials are 8-amino-1- {4- [ (aminothio) peroxy] phenyl}-4, 5-dihydro-lH-benzo [g] indazole-3-carboxamide (Example 4) and appropriate sulfonyl chlorides, acyl chlorides and isocyanates.

Twenty-eight reactions were done in this library.

The general procedure is as follows: 48 mg of 8-amino-1- {4- [ (aminothio) peroxy] phenyl}-lH-benzo [g] indazole-3-carboxamide in 1 mL pyridine was placed in each reaction vessel, then 1.2 eq. of a sulfonyl chloride was added, and the mixture was shaken overnight. Then 3 mL methylene chloride and 300 mg of resin PS-trisamine were added, and then shaken over night. After filtration and washing with 2 mL methanol twice, the filtrates were combined and solvents evaporated. The residue was dissolved in 2 mL dimethylformamide, and MS-TsOH resin (450 mg) was added and shaken for 48 hours. After filtration and washing with 2 mL DMF, the combined filtrate was analyzed by LC-MS and LC. Then the filtrate was evaporated on a SpeedVac and the residue were suspended in 2 mL of H20/tBuOH, and lyophilized for 2 days. All compounds were obtained in solid form, and the majority of the compounds have about 90% purity.

[0086] Isolation of rhlKK1 homodimer Cells from an 8 liter fermentation of baculovirus-expressed IKK1 tagged with His peptide were centrifuged and the cell pellet (MOI 0.1, I=72 hr) was re- suspended in 100 ml of buffer C. The cells were microfluidized and centrifuged at 100,000 X g for 45 min. The supernatant was collected, imidazole added to the final concentration of 10 mM and incubated with 25 ml of Ni-NTA resin for 2 hrs. The suspension was poured into a 25 ml column and washed with 250 ml of buffer C and then with 125 ml of 50 mM imidazole in buffer C. rhIKKI homodimer was eluted using 300 mM imidazole in buffer C. BSA and NP-40 were added to the enzyme fractions to the final concentration of 0.1 %. The enzyme was dialyzed against buffer B, aliquoted and stored at-80 °C.

[0087] Isolation of rhIKK2 homodimer

A 10 liter culture of baculovirus-expressing IKK2 tagged with FLAG peptide was centrifuged and the cell pellet (MOI=0. 1 and I=72 hrs) was re-suspended in buffer A. These cells were microfluidized, and centrifuged at 100,000 X g for 45 min. Supernatant was passed over a G-25 column equilibrated with Buffer A. Protein peak was collected and incubated with anti-FLAG affinity resin on a rotator overnight in buffer B. The resin was washed in batch with 10-15 bed volumes of buffer C. Washed resin was poured into a column and rhIKK2 homodimer was eluted using 5 bed volumes of buffer B containing FLAG peptide. 5 mM DTT, 0.1% NP-40 and BSA (concentrated to 0.1% in final amount) was added to the eluted enzyme before concentrating in using an Amicon membrane with a molecular weight cut-off of 30 kDa. Enzyme was aliquoted and stored at-80 °C.

[0088] Isolation of rhIKKIlIKK2 heterodimer The heterodimer enzyme was produced by coinfection in a baculovirus system (FLAG IKK2/IKK1 His ; MOI=0. 1 and I=72 hrs). Infected cells were centrifuged and the cell pellet (10. 0 g) was suspended in 50 ml of buffer A. The protein suspension was microfluidized and centrifuged at 100,000 X g for 45 min. Imidazole was added to the supernatant to a final concentration of 10 mM.

The protein was allowed to bind 25 ml of Ni-NTA resin by mixing for 2 hrs.

The protein-resin slurry was poured into a 25 ml column and washed with 250 ml of buffer A containing 10 mM imidazole followed by 125 ml of buffer A containing 50 mM imidazole. Buffer A, containing 300 mM imidazole, was then used to elute the protein. A 75 ml pool was collected and NP-40 was added to a final concentration of 0.1%. The protein solution was then dialyzed against buffer B. The dialyzed heterodimer enzyme was then allowed to bind to 25 ml of anti-FLAG M2 agarose affinity gel overnight with constant mixing.

Enzyme fractions (100 ml) were collected and concentrated to 20 ml using an Amicon membrane with molecular weight cut-off of 30 kDa. Bovine serum albumin was added to the concentrated enzyme to final concentration of 0.1 %. The enzyme was then aliquoted and stored at-80 °C.

[0089] Cell Culture The wild type (wt) human pre-B cell line, 70Z/3, and its mutant, 1.3E2, were generously provided by Dr. Carol Sibley. Wt 70Z/3 and 1.3E2 cells were grown in RPMI 1640 (Gibco) supplemented with 7 % defined bovine serum (Hyclone) and 50 RM 2-mercaptoethanol. Human monocytic leukemia THP-1 cells, obtained from ATCC, were cultured in RPMI 1640 supplemented with 10% defined bovine serum, 10 mM HEPES, 1.0 mM sodium pyruvate and 50 uM 2- mercaptoethanol. For experiments, cells were plated in 6 well plates at 1x106 cells/ml in fresh media. Pre-B cells were stimulated by the addition of 10 llg/ml LPS for varying lengths of time ranging from 0-4 hr. THP-1 cells were stimulated by the addition of 1 pg/ml LPS for 45 minutes. Cells were pelleted, washed with cold 50 mM sodium phosphate buffer, pH 7.4 containing 0.15 M NaCl and lysed at 4 °C in 20 mM Hepes buffer, pH 7.6 containing 50 mM NaCI, 1 mM EDTA, 1 mM EGTA, 1 mM sodium orthovanadate, 10 mM ß- glycerophosphate, 1 mM NaF, 1 mM PMSF, 1 mM DTT and 0.5 % NP40 (lysis buffer). The cytosolic fractions obtained following centrifugation at 10,000 X g were stored at-80° C until used.

[0090] Immunoprecipitation and Western Blotting SF9 cells paste containing rhIKKs were centrifuged (100,000 X g, 10 min) to remove debris. rhIKKs were immunoprecipitated (100 Zg of cell paste) from the cell supernatant using 3 Flg of anti-NEMO antibody (FL-419), followed by

coupling to protein A sepharose beads. rhIKKs were also immunoprecipitated from affinity chromatography purified protein preparations (1 Zg) using anti- FLAG, anti-His or anti-NEMO antibodies (1-4 tg) followed by protein A sepharose coupling. The native, human IKK complex was immunoprecipitated from THP-1 cell homogenates (300 llg/condition) using the anti-NEMO antibody. Immune complexes were pelleted and washed 3 times with 1 ml cold lysis buffer. Immunoprecipitated rhIKKs were chromatographed by SDS-PAGE (8% Tris-glycine) and transferred to nitrocellulose membranes (Novex) and detected by chemiluminescense (SuperSignal) using specific anti-IKK antibodies (IKK2 H-470, IKK1 H-744). Native IKK2, IKB (X and NEMO proteins from cytosolic lysates (20-80 Zg) were separated by SDS-PAGE and visualized by chemiluminescense using specific antibodies.

[0091] Phosphatase Treatment Immunoprecipitated rhIKKs were washed 2 times in 50 mM Tris-HCl, pH 8.2 containing 0.1 mM EDTA, 1 mM DTT, 1 mM PMSF and 2 mM MnCl2 and resuspended in 50 J. Phosphatase (#PPase, 1000 U) was pre-diluted in the same buffer and added to the IKK samples. Following an incubation at room temperature for 30 minutes with intermittent mixing, cold lysis buffer was added to the tubes to stop the reaction. After several washes, 10 % of the beads were removed for Western analysis, and the remaining material was pelleted and resuspended in 100 ul of the buffer used for the in vitro kinase assay.

[0092] IKKASAM Enzyme Assay IKKa kinase activity was measured using a biotinylated IlcBa peptide (Gly-Leu- Lys-Lys-Glu-Arg-Leu-Leu-Asp-Asp-Arg-His-Asp-Ser32-Gly-Leu-As p-Ser36- Met-Lys-Asp-Glu-Glu), a SAM2 TM 96 Biotin capture plate, and a vacuum system. The standard reaction mixture contained 5 FM biotinylated IKBoc peptide, 1 zM [^y-33P] ATP (about 1 X 105 cpm), 1 mM DTT, 50 mM KCI, 2

mM MgCl2, 2 mM MnCl2, 10 mM NaF, 25 mM Hepes buffer, pH. 7.6 and enzyme solution (1-10 gel) in a final volume of 50 u. I. After incubation at 25 °C for 30 min, 25 Ill of the reaction mixture was withdrawn and added to a SAM2 TM 96 Biotin capture 96-well plate. Each well was then washed successively with 800 gl 2 M NaCl, 1.2 ml of NaCl containing 1% H3PO4, 400 ul H20, and 200 Ill 95% ethanol. The plate was allowed to dry in a hood at 25 °C for 1 hr and then 25 u. I of scintillation fluid (Microscint 20) was added to each well.

Incorporation of [y-33P] ATP was measured using a Top-Count NXT (Packard).

Under each assay condition, the degree of phosphorylation of IKB (X peptide substrate was linear with time and concentration for all purified enzymes.

Results from the biotinylated peptide assay were confirmed by SDS-PAGE analysis of kinase reaction utilizing a GST-I#Bα1 -54 and [γ-32P] ATP. The resulting radiolabeled substrate was quantitated by Phosphoimager (Molecular Dynamics). An ion exchange resin assay was also employed using [γ-33P] ATP and GST-I#Bα1-54 fusion protein as the substrates. Each assay system yielded consistent results in regard to Km and specific activities for each of the purified kinase isoforms. One unit of enzyme activity was defined as the amount required to catalyze the transfer of 1 nmole of phosphate from ATP to IKB (X peptide per min. Specific activity was expressed as units per mg of protein. For experiments related to Km determination of purified enzymes, various concentrations of ATP or IKB (X peptide were used in the assay at either a fixed IKBa or ATP concentration. For IKB (X peptide Km, assays were carried out with 0.1 gg of enzyme, 5 uM ATP and I#Bα peptide from 0.5 to 20 uM. For ATP Km, assays were carried out with 0.1 Zg of enzyme, 10 uM I#Bα peptide and ATP from 0.1 to 10 uM. For Km determination of rhIKK1 homodimer, due to its low activity and higher Km for I#Bα peptide, rhIKK1 homodimer (0.3 Zg) was assayed with 125 uM IKB (X peptide and a 5-fold higher specific activity of ATP (from 0.1 to 10 uM) for ATP Km experiments and a 5-fold higher specific activity of 5 uM ATP and I#Bα peptide (from 5 to 200 µM) for IKBa peptide Km experiments.

[0093] IKK, 6Resin Enzyme Assay IKKß kinase activity was measured using a biotinylated IKB (X peptide (Gly-Leu- Lys-Lys-Glu-Arg-Leu-Leu-Asp-Asp-Arg-His-Asp-Ser32-Gly-Leu-As p-Ser36- Met-Lys-Asp-Glu-Glu) (American Peptide Co. ). 20 ul of the standard reaction mixture contained 5 uM biotinylated IKB (X peptide, 0.1 IlCi/reaction [Y-33P] ATP (Amersham) (about 1 X 105 cpm), 1 µM ATP (Sigma), 1 mM DTT (Sigma), 2 mM MgCl2 (Sigma), 2 mM MnCl2 (Sigma), 10 mM NaF (Sigma), 25 mM Hepes (Sigma) buffer, pH 7.6 and 20 Zl enzyme solution and 10 ul inhibitor in a final volume of 50 ul. After incubation at 25 °C for 30 min, 150 ZI resin (Dowex anion-exchange resin AG1X8 200-400 mesh) in 900 mM formate, pH 3.0 was added to each well to stop the reaction. Resin was allowed to settle for one hour and 50 ul of supernatant was removed to a Micolite-2 flat bottom plate (Dynex). 150 1 of scintillation fluid (Microscint 40) (Packard) was added to each well. Incorporation of [γ-33P] ATP was measured using a Top-Count NXT (Packard).

M ATP (Sigma), 1 mM DTT (Sigma), 2 mM MgCl2 (Sigma), 2 mM MnCl2 (Sigma), 10 mM NaF (Sigma), 25 mM Hepes (Sigma) buffer, pH 7.6 and 20 Fl enzyme solution and 10 gaz inhibitor in a final volume of 50 1. After incubation at 25 °C for 30 min, 150 u. l resin (Dowex anion-exchange resin AG1X8 200-400 mesh) in 900 mM formate, pH 3.0 was added to each well to stop the reaction.
