Priority is claimed under 35 U.S.C. § 120 with respect to U.S. Serial No. 09/316,761 filed 21 May 1999. The contents of these applications are incorporated herein by reference in their entirety. Field of the Invention The invention relates to treating various disorders associated with enhanced activity of kinase p38. α More specifically, it concerns compounds that are related to indole-type derivatives coupled to piperazine- or piperidine-type moieties as useful in these methods. Background Art A large number of chronic and acute conditions have been recognized to be associated with perturbation of the inflammatory response. A large number of cytokines participate in this response, including IL-1, IL-6, IL-8 and TNF. It appears that the activity of these cytokines in the regulation of inflammation rely at least in part on the activation of an enzyme on the cell signaling pathway, a member of the MAP kinase family generally known as p38 and alternatively known as CSBP and RK. This kinase is activated by dual phosphorylation after stimulation by physiochemical stress, treatment with lipopolysaccharides or with proinflammatory cytokines such as IL-1 and TNF. Therefore, inhibitors of the kinase activity of p38 are useful anti-inflammatory agents. Eye diseases associated with a fibroproliferative condition include retinal reattachment surgery accompanying proliferative vitreoretinopathy, cataract extraction with intraocular lens implantation, and post glaucoma drainage surgery. PCT applications WO98/06715, WO98/07425, and WO 96/40143, all of which are incorporated herein by reference, describe the relationship of p38 kinase inhibitors with various disease states. As mentioned in these applications, inhibitors of p38 kinase are useful in treating a variety of diseases associated with chronic inflammation. These applications list rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions, sepsis, septic shock, endotoxic shock, Gram-negative sepsis, toxic shock syndrome, asthma, adult respiratory distress syndrome, stroke, reperfusion injury, CNS injuries such as neural trauma and ischemia, psoriasis, restenosis, cerebral malaria, chronic pulmonary inflammatory disease, silicosis, pulmonary sarcosis, bone resorption diseases such as osteoporosis, graft-versus-host reaction, Crohn's Disease, 5 ulcerative colitis including inflammatory bowel disease (IBD) and pyresis. The above-referenced PCT applications disclose compounds which are p38 kinase inhibitors said to be useful in treating these disease states. These compounds are either imidazoles or are indoles substituted at the 3- or 4-position with a piperazine ring linked through a carboxamide linkage. Additional compounds which are conjugates of o piperazines with indoles are described as insecticides in WO97/26252, also incorporated herein by reference. Certain aroyl/phenyl-substituted piperazines and piperidines which inhibit p38- α kinase are described in PCT publication WO00/12074 published 9 March 2000. In addition, indolyl substituted piperidines and piperazines which inhibit this enzyme are described in 5 PCT publication No. WO99/61426 published 2 December 1999. Carbolene derivatives of piperidine and piperazine as p38- α inhibitors are described in PCT/USOO/07934 filed 24 March 2000. None of the foregoing patents describes the indole derivatives described herein which specifically inhibit p38. α 0 Disclosure of the Invention The invention is directed to methods and compounds useful in treating conditions that are characterized by enhanced p38. α activity. These conditions include inflammation, proliferative diseases, and certain cardiovascular disorders as well as Alzheimer's disease as further described below. 5 Compounds of the invention have been found to inhibit p38 kinase, the α"i so f orm m particular, and are thus useful in treating diseases mediated by these activities. The compounds of the invention are of the formula and the pharmaceutically acceptable salts thereof, or a pharmaceutical composition thereof, wherein ■ represents a single or double bond; one Z 2 is CA or CR 8 A and the other is CR 1 , CR 1 .,, NR 6 or N wherein each R 1 , R and R 8 is independently hydrogen or noninterfering substituent; A is -W.-COX.Y wherein Y is COR 2 or an isostere thereof and R 2 is hydrogen or a noninterfering substituent, each of W and X is a spacer of 2-6A, and each of i and j is independently 0 or 1 ; Z3 is NR 7 or O; each R 3 is independently a noninterfering substituent; n is 0-3; each of L 1 and L 2 is a linker; each R 4 is independently a noninterfering substituent; m is 0-4; Z 1 is CR 5 or N wherein R 5 is hydrogen or a noninterfering substituent; each of 1 and k is an integer from 0-2 wherein the sum of 1 and k is 0-3; Ar is an aryl group substituted with 0-5 noninterfering substituents, wherein two noninterfering substituents can form a fused ring; and the distance between the atom of Ar linked to L 2 anc ι the center of the α ring is 4.5-24A. The invention is directed to methods of treating inflammation or proliferative conditions using these compounds. The invention is also directed to treating conditions associated with cardiac failure and Alzheimer's disease using the invention compounds. Modes of Carrying Out the Invention The compounds of formula (1) are useful in treating conditions which are characterized by overactivity of p38 kinase, in particular the <r isoform - Conditions "characterized by enhanced p38. α activity" include those where this enzyme is present in increased amount or wherein the enzyme has been modified to increase its inherent activity, or both. Thus, "enhanced activity" refers to any condition wherein the effectiveness of these proteins is undesirably high, regardless of the cause. The compounds of the invention are useful in conditions where p38. α kinase shows enhanced activity. These conditions are those in which fibrosis and organ sclerosis are caused by, or accompanied by, inflammation, oxidation injury, hypoxia, altered temperature or extracellular osmolarity, conditions causing cellular stress, apoptosis or necrosis. These conditions include ischemia-reperfusion injury, congestive heart failure, progressive pulmonary and bronchial fibrosis, hepatitis, arthritis, inflammatory bowel disease, glomerular sclerosis, interstitial renal fibrosis, chronic scarring diseases of the eyes, bladder and reproductive tract, bone marrow dysplasia, chronic infectious or autoimmune states and traumatic or surgical wounds. These conditions, of course, would be benefited by compounds which inhibit p38. α . Methods of treatment with the compounds of the invention are further discussed below. The Invention Compounds The compounds useful in the invention are derivatives of indole-type compounds containing a mandatory substituent, A, at a position corresponding to the 2- or 3- position of indole. In general, an indole-type nucleus is preferred, although alternatives within the scope of the invention are also illustrated below. In the description above, certain positions of the molecule are described as permitting "noninterfering substituents." This terminology is used because the substituents in these positions generally speaking are not relevant to the essential activity of the molecule taken as a whole. A wide variety of substituents can be employed in these positions, and it is well within ordinary skill to determine whether any particular arbitrary substituent is or is not "noninterfering." As used herein, a "noninterfering substituent" is a substituent which leaves the ability of the compound of formula (1) to inhibit p38. α activity qualitatively intact. Thus, the substituent may alter the degree of inhibition of p38. α However, as long as me compound of formula (1) retains the ability to inhibit p38. α activity, the substituent will be classified as "noninterfering." A number of assays for determining the ability of any compound to inhibit p38- α activity are available in the art. A whole blood assay for this evaluation is illustrated below: the gene for p38- α has been cloned and the protein can be prepared recombinantly and its activity assessed, including an assessment of the ability of an arbitrarily chosen compound to interfere with this activity. The essential features of the molecule are tightly defined. The positions which are occupied by "noninterfering substituents" can be substituted by conventional organic moieties as is understood in the art. It is irrelevant to the present invention to test the outer limits of such substitutions. The essential features of the compounds are those set forth with particularity herein. In addition, L 1 and L 2 are described herein as linkers. The nature of such linkers is less important that the distance they impart between the portions of the molecule. Typical linkers include alkylene, e (CH 2 ) n -R; alkenylene - e , an alkylene moiety which contains a double bond, including a double bond at one terminus. Other suitable linkers include, for example, substituted alkylenes or alkenylenes, carbonyl moieties, and the like. As used herein, "hydrocarbyl residue" refers to a residue which contains only carbon and hydrogen. The residue may be aliphatic or aromatic, straight-chain, cyclic, branched, saturated or unsaturated. The hydrocarbyl residue, when so stated however, may contain heteroatoms over and above the carbon and hydrogen members of the substituent residue. Thus, when specifically noted as containing such heteroatoms, the hydrocarbyl residue may also contain carbonyl groups, amino groups, hydroxyl groups and the like, or contain heteroatoms within the "backbone" of the hydrocarbyl residue. As used herein, "inorganic residue" refers to a residue that does not contain carbon. Examples include, but are not limited to, halo, hydroxy, N0 2 or NH r As used herein, the term "alkyl," "alkenyl" and "alkynyl" include straight- and branched- chain and cyclic monovalent substituents. Examples include methyl, ethyl, isobutyl, cyclohexyl, cyclopentylethyl, 2-propenyl, 3-butynyl, and the like. Typically, the alkyl, alkenyl and alkynyl substituents contain 1-lOC (alkyl) or 2- IOC (alkenyl or alkynyl). Preferably they contain 1-6C (alkyl) or 2-6C (alkenyl or alkynyl). Heteroalkyl, heteroalkenyl and heteroalkynyl are similarly defined but may contain 1-2 O, S or N heteroatoms or combinations thereof within the backbone residue. As used herein, "acyl" encompasses the definitions of alkyl, alkenyl, alkynyl and the related hetero-forms which are coupled to an additional residue through a carbonyl group. "Aromatic" moiety refers to a monocyclic or fused bicyclic moiety such as phenyl or naphthyl; "heteroaromatic" also refers to monocyclic or fused bicyclic ring systems containing one or more heteroatoms selected from O, S and N. The inclusion of a heteroatom permits inclusion of 5-membered rings as well as 6-membered rings. Thus, typical aromatic systems include pyridyl, pyrimidyl, indolyl, benzimidazolyl, benzotriazolyl, isoquinolyl, quinolyl, benzothiazolyl, benzofuranyl, thienyl, furyl, pyrrolyl, thiazolyl, oxazolyl, imidazolyl and the like. Any monocyclic or fused ring bicyclic system which has the characteristics of aromaticity in terms of electron distribution throughout the ring system is included in this definition. Typically, the ring systems contain 5-12 ring member atoms. Similarly, "arylalkyl" and "heteroalkyl" refer to aromatic and heteroaromatic systems 5 which are coupled to another residue through a carbon chain, including substituted or unsubstituted, saturated or unsaturated, carbon chains, typically of 1-6C. These carbon chains may also include a carbonyl group, thus making them able to provide substituents as an acyl moiety. When the compounds of Formula 1 contain one or more chiral centers, the invention o includes optically pure forms as well as mixtures of stereoisomers or enantiomers With respect to the portion of the compound between the atom of Ar bound to L 2 and ring α, L 1 anc * L 2 are linkers which space the substituent Ar from ring α at a distance of 4.5-24A, preferably 6-20A, more preferably 7.5-lθA.

Similarly, embodiments wherein the indole-type moiety is can be used in these schemes. Methods to synthesize the compounds of the invention are, in general, known in the art. The following general schemes illustrate such methods. Scheme 1 Substituted amino benzoic acid esters such as i can be treated with reagents such as thiomethylacetaldehyde dimethyl acetal and N-chlorosuccinamide in methylene chloride at low temperature followed by the treatment with a base such as triethylamine at reflux in methylene chloride, dichloroethane or chloroform to give indoles JJ, Scheme 1. Treatment with reagents such as Raney-Nickel in an appropriate solvent such as ethanol, methanol or isopropanol will yield the corresponding indole carboxylic acid ester which when hydrolyzed under base conditions will give the desired substituted indole carboxylic acid. Scheme 2 Alternatively, substituted amino benzoic acid esters i can be converted to the ketals jy, Scheme 2, with an appropriate aldehyde under conditions of reductive alkylation with reagents such as sodium triacetoxyborohydride in acetic acid in the presence of sodium sulfate. The amines can then be treated with lewis acids such as aluminum chloride, titanium chloride, BF 3 -etherate in dichloromethane or dichloroethane, under reflux to give the corresponding substituted indole methyl esters, with appropriate substitutions. L = OF ! or SiR 3 Scheme 3 Another method could involve the treatment of the substituted amino benzoic acid esters j with iodine and sodium periodate in an appropriate solvent such as dimethyformamide, to give the corresponding iodo aniline y, Scheme 3. This can be coupled with an acetylene such as trimethyl silyl acetylene or ethylethynyl ether in the presence of an appropriate catalysts such as palladium and copper and a base such as triethylamine to give the silyl coupled product such as γi- Subsequent cyclization in a solvent such as dimethylformamide and in the presence of a catalyst such as copper iodide would give the appropriately substituted indoles vil- Scheme 4 Synthesis of the required piperidines can be achieved by treating an appropriate piperidone such as VIIL Scheme 4, with substituted benzyl phosphonate esters in the presence of a base such as sodium hydride to give alkenes which can be reduced to the corresponding substituted 4-benzylpiperidine such as ιχ. The hydrogenations are typically done in the presence of catalytic metals in solvents such as methanol, ethanol and ethyl acetate. Scheme 5 An alternate method could involve isonipecotoyl chlorides such as x which can be used to acylate appropriately substituted benzenes (ArH) in the presence of a lewis acid such as aluminum chloride to give the ketones χι, Scheme 5. Further modifications of the carbonyl moiety of χι using methods and routes generally known can then lead to the desired compounds xij.

Subsequent acylation to XXII can be achieved with an acylating agent such as acetic anhydride in the presence of a catalyst such as Fe(III). Oxidation of the acetyl moiety of χχιj to the glyoxalic acid moiety of χχiπ can be accomplished using an oxidizing agent such as selenium dioxide (Ref: F Da Settimo et al. Eur. J. Med. Chem (1996), 31, 951-956; M. C. Cook, et al. (1975) Br patent 1, 399,089.; E. Campaigne, et al. J. Med. Chem. (1965), 136-137). Finally coupling of the acid with the appropriate neucleophile in WH can be achieved using any one of the variety of coupling agents known in a variety of solvents to give compounds of type χχιv- Assays for p38 α Kinase Inhibition For each of the assay procedures described below, the TNF. α production correlates to the activity of p38. α nase. A. Human Whole Blood Assay for p38 Kinase Inhibition Venous blood is collected from healthy male volunteers into a heparinized syringe and is used within 2 hours of collection. Test compounds are dissolved in 100% DMSO and 1 μi aliquots of drug concentrations ranging from 0 to 1 mM are dispensed into quadruplicate wells of a 24-well microtiter plate (Nunclon Delta SI, Applied Scientific, So. San Francisco, CA). Whole blood is added at a volume of 1 ml/well and the mixture is incubated for 15 minutes with constant shaking (Titer Plate Shaker, Lab-Line Instruments, Inc., Melrose Park, IL) at a humidified atmosphere of 5% CO 2 at 37°C. Whole blood is cultured either undiluted or at a final dilution of 1:10 with RPMI 1640 (Gibco 31800 + NaHC0 3 , Life Technologies, Rockville, MD and Scios, Inc., Sunnyvale, CA). At the end of the incubation period, 10 μj 0 f LPS (E. coli 0111 :B4, Sigma Chemical Co., St. Louis, MO) is added to each well to a final concentration of 1 or 0.1 μg/ml for undiluted or 1:10 diluted whole blood, respectively. The incubation is continued for an additional 2 hours. The reaction is stopped by placing the microtiter plates in an ice bath and plasma or cell- free supemates are collected by centrifugation at 3000 rpm for 10 minutes at 4°C. The plasma samples are stored at -80°C until assayed for TNF. α levels by ELISA, following the directions supplied by Quantikine Human TNF. α assa y ki (R&D Systems, Minneapolis, MN). IC 50 values are calculated using the concentration of inhibitor that causes a 50% decrease as compared to a control. B. Enriched Mononuclear Cell Assay for p38 Kinase Inhibition The enriched mononuclear cell assay, the protocol of which is set forth below, begins with cryopreserved Human Peripheral Blood Mononuclear Cells (HPBMCs) (Clonetics Corp.) that are rinsed and resuspended in a warm mixture of cell growth media. The resuspended cells are then counted and seeded at lxl 0 6 cells/well in a 24-well microtitre plate. The plates are then placed in an incubator for an hour to allow the cells to settle in each well. After the cells have settled, the media is aspirated and new media containing 100 ng/ml of the cytokine stimulatory factor Lipopolysaccharide (LPS) and a test chemical compound is added to each well of the microtiter plate. Thus, each well contains HPBMCs, LPS and a test chemical compound. The cells are then incubated for 2 hours, and the amount of the cytokine Tumor Necrosis Factor Alpha (TNF. α ) j s mea sured using an Enzyme Linked Immunoassay (ELISA). One such ELISA for detecting the levels of TNF. α j s commercially available from R&D Systems. The amount of TNF. α production by the HPBMCs in each well is then compared to a control well to determine whether the chemical compound acts as an inhibitor of cytokine production.

Remove supematants after incubation to a labeled tube and either perform TNF (or other) ELISA immediately or freeze for later assay. IC 50 values are calculated using the concentration of inhibitor that causes a 50% decrease as compared to a control. Administration and Use The compounds of the invention are useful among other indications in treating conditions associated with inflammation. Thus, the compounds of formula (1) or their pharmaceutically acceptable salts are used in the manufacture of a medicament for prophylactic or therapeutic treatment of mammals, including humans, in respect of conditions characterized by excessive production of cytokines and/or inappropriate or unregulated cytokine activity on such cells as cardiomyocytes, cardiofibroblasts and macrophages. The compounds of the invention inhibit the production of cytokines such as TNF, IL-1, IL-6 and IL-8, cytokines that are important proinflammatory constituents in many different disease states and syndromes. Thus, inhibition of these cytokines has benefit in controlling and mitigating many diseases. The compounds of the invention are shown herein to inhibit a member of the MAP kinase family variously called p38 MAPK (or p38), CSBP, or SAPK-2. The activation of this protein has been shown to accompany exacerbation of the diseases in response to stress caused, for example, by treatment with lipopolysaccharides or cytokines such as TNF and IL-1. Inhibition of p38 activity, therefore, is predictive of the ability of a medicament to provide a beneficial effect in treating diseases such as Alzheimer's, coronary artery disease, congestive heart failure, cardiomyopathy, myocarditis, vasculitis, restenosis, such as occurs following coronary angioplasty, atherosclerosis, IBD, rheumatoid arthritis, rheumatoid spondylitis, osteoarthritis, gouty arthritis and other arthritic conditions, multiple sclerosis, acute respiratory distress syndrome (ARDS), asthma, chronic obstructive pulmonary disease (COPD), silicosis, pulmonary sarcosis, sepsis, septic shock, endotoxic shock. Gram- negative sepsis, toxic shock syndrome, heart and brain failure (stroke) that are characterized by ischemia and reperfusion injury, surgical procedures, such as transplantation procedures and graft rejections, cardiopulmonary bypass, coronary artery bypass graft, CNS injuries, including open and closed head trauma, inflammatory eye conditions such as conjunctivitis and uveitis, acute renal failure, glomerulonephritis, inflammatory bowel diseases, such as Crohn's disease or ulcerative colitis, graft vs. host disease, bone resorption diseases like osteoporosis, type II diabetes, pyresis, psoriasis, cachexia, viral diseases such as those caused by HIV, CMV, and Heφes, and cerebral malaria. Within the last several years, p38 has been shown to comprise a group of MAP kinases designated p38. α? p 8 .β 5 p 38 -γ and p38-δ. Jiang, Y., et al, J Biol Chem O 996 ) 271:17920-17926 reported characterization of p38.β ^ a 372-amino acid protein closely related to p38. α ι n comparing the activity of p38-α with that of p38-β, the authors state that while both are activated by proinflammatory cytokines and environmental stress, P 38 -β was preferentially activated by MAP kinase kinase" 6 (MKK6) and preferentially activated transcription factor 2, thus suggesting that separate mechanisms for action may be associated with these forms. Kumar, S., et α /_ f Biochem Biophys Res Comm ( 19 97) 235:533-538 and Stein, B., et al ; j Biol Chem (1997) 272:19509-19517 reported a second isoform of p38.β 5 p 38-β2, containing 364 amino acids with 73% identity to p38. α j^\ 0 f these reports show evidence that p38.β j s activated by proinflammatory cytokines and environmental stress, although the second reported p38.β i so form, p38-β2, appears to be preferentially expressed in the CNS, heart and skeletal muscle compared to the more ubiquitous tissue expression of p38. α . Furthermore, activated transcription factor 2 (ATF-2) was observed to be a better substrate for p38.β2 than for p38-α, thus suggesting that separate mechanisms of action may be associated with these forms. The physiological role of p38.βi has been called into question by the latter two reports since it cannot be found in human tissue and does not exhibit appreciable kinase activity with the substrates of p38. α The identification of p38. γ was reported by Li, Z., et al, Biochem Biophys Res Comm (1996) 228:334-340 and of p38. δ by Wang, X., et a J Biol Chem (1997) 272:23668- 23674 and by Kumar, S., et a Biochem Biophys Res Comm ( 19 97) 235:533-538. The data suggest that these two p38 isoforms (γ and δ) represent a unique subset of the MAPK family based on their tissue expression patterns, substrate utilization, response to direct and indirect stimuli, and susceptibility to kinase inhibitors. Various results with regard to response to drugs targeting the p38 family as between p38. α and either the putative p38.βi or p 38-β2 or both were reported by Jiang, Kumar, and Stein cited above as well as by Eyers, P.A., et a [ Chem and Biol (1995) 5:321-328. An additional paper by Wang, Y., et α / J Biol Chem (1998) 273:2161-2168 suggests the significance of such differential effects. As pointed out by Wang, a number of stimuli, such as myocardial infarction, hypertension, valvular diseases, viral myocarditis, and dilated cardiomyopathy lead to an increase in cardiac workload and elevated mechanical stress on cardiomyocytes. These are said to lead to an adaptive hypertrophic response which, if not controlled, has decidedly negative consequences. Wang cites previous studies which have shown that in ischemia reperfusion treated hearts, p38 MAPK activities are elevated in association with hypertrophy and programmed cell death. Wang shows in the cited paper that activation of p38.β activity results in hypertrophy, whereas activation of p38. α activity leads to myocyte apoptosis. τhus > selective inhibition of p38. α activity as compared to p38.β activity will be of benefit in treating conditions associated with cardiac failure. These conditions include congestive heart failure, cardiomyopathy, myocarditis, vasculitis, vascular restenosis, valvular disease, conditions associated with cardiopulmonary bypass, coronary artery bypass, grafts and vascular grafts. Further, to the extent that the α-isoform is toxic in other muscle cell types, cr selective inhibitors would be useful for conditions associated with cachexia attributed to TNF or other conditions such as cancer, infection, or autoimmune disease. Thus, the invention encompasses the use of compounds which selectively inhibit the activity of the p38. α i so form for treating conditions associated with activation of p38. α? j n particular those associated with cardiac hypertrophy, ischemia or other environmental stress such as oxidation injury, hyperosmolarity or other agents or factors that activate P 38 -α kinase, or cardiac failure, for e xam P le > congestive heart failure, cardiomyopathy and myocarditis. The manner of administration and formulation of the compounds useful in the invention and their related compounds will depend on the nature of the condition, the severity of the condition, the particular subject to be treated, and the judgement of the practitioner; formulation will depend on mode of administration. As the compounds of the invention are small molecules, they are conveniently administered by oral administration by compounding them with suitable pharmaceutical excipients so as to provide tablets, capsules, syrups, and the like. Suitable formulations for oral administration may also include minor components such as buffers, flavoring agents and the like. Typically, the amount of active ingredient in the formulations will be in the range of 5%-95% of the total formulation, but wide variation is permitted depending on the carrier. Suitable carriers include sucrose, pectin, magnesium stearate, lactose, peanut oil, olive oil, water, and the like - The compounds useful in the invention may also be administered through suppositories or other transmucosal vehicles. Typically, such formulations will include excipients that facilitate the passage of the compound through the mucosa such as pharmaceutically acceptable detergents. The compounds may also be administered topically, for topical conditions such as psoriasis, or in formulation intended to penetrate the skin. These include lotions, creams, ointments and the like which can be formulated by known methods. The compounds may also be administered by injection, including intravenous, intramuscular, subcutaneous or intraperitoneal injection. Typical formulations for such use are liquid formulations in isotonic vehicles such as Hank's solution or Ringer's solution. Alternative formulations include nasal sprays, liposomal formulations, slow-release formulations, and the like, as are known in the art. Any suitable formulation may be used. A compendium of art-known formulations is found in Remington's Pharmaceutical Sciences, latest edition, Mack Publishing Company, Easton, PA. Reference to this manual is routine in the art.

However, it is believed that generally, the daily oral dosage will utilize 0.001-100 mg/kg total body weight, preferably from 0.01-50 mg/kg and more preferably about 0.01 mg/kg- 10 mg/kg. The dose regimen will vary, however, depending on the conditions being treated and the judgment of the practitioner. It should be noted that the compounds of formula (1) can be administered as individual active ingredients, or as mixtures of several embodiments of this formula. In addition, the inhibitors of p38 kinase can be used as single therapeutic agents or in combination with other therapeutic agents. Drugs that could be usefully combined with these compounds include natural or synthetic corticosteroids, particularly prednisone and its derivatives, monoclonal antibodies targeting cells of the immune system, antibodies or soluble receptors or receptor fusion proteins targeting immune or non-immune cytokines, and small molecule inhibitors of cell division, protein synthesis, or mRNA transcription or translation, or inhibitors of immune cell differentiation or activation.
