This detailed description herein is intended only to acquaint others skilled in the art with the inventions, the principles, and the practical applications so that others skilled in the art may adapt and apply the inventions in their numerous forms, as they may be best suited to the requirements of a particular use. These inventions, therefore, are not limited to the embodiments described in this specification, and may be modified.

A. Definitions

The term "subject" refers to any animal, including mammals, such as mice, rats, other rodents, rabbits, dogs, cats, pigs, cattle, sheep, horses, primates, or humans. The term "treating" (and corresponding terms "treat" and "treatment") includes palliative, restorative, and preventative ("prophylactic") treating of a subject. The term "palliative treating" refers to treatment that eases or reduces the effect or intensity of a condition in a subject without curing the condition. The term "preventative treating" (and the corresponding term "prophylactic treating") refers to treatment that prevents the occurrence of a condition in a subject. The term "restorative treating" ("curative") refers to treatment that halts the progression of, reduces the pathologic manifestations of, or entirely eliminates a condition in a subject. Treating can be done with a therapeutically effective amount of compound, salt or composition that elicits the biological or medicinal response of a tissue, system or subject that is being sought by an individual such as a patient, researcher, doctor, veterinarian, or clinician

The terms "pharmaceutically effective" or "therapeutically effective" refer to an amount of a compound herein, or salt thereof, that is sufficient to provide an effective treatment, as discussed above It is understood that what comprises a pharmaceutically or therapeutically effective amount may be a lesser amount of the compound or salt when it is administered in combination with another agent than when utilized alone

comprising administering to the subject a compound or salt of the present invention.

The present invention includes a method of treating conditions such as asthma, dermatitis, inflammatory bowel disease, Alzheimer's disease, psychotic major depression, neuropathy, transplant rejection, multiple sclerosis, chronic uveitis, or chronic obstructive pulmonary disease in a subject comprising administering to the subject a compound or salt of the present invention.

The present invention includes a method of treating rheumatoid arthritis in a subject comprising administering to the subject a compound or salt of the present invention. Rheumatoid arthritis is considered a chronic autoimmune and inflammatory disease producing inflamed joints, which eventually swell, become painful, and experience degradation of cartilage, bone, and ligaments of the joint. A result of rheumatoid arthritis is deformity, instability, and stiffness of the joint and scarring within the joint. The joints deteriorate at a highly variable rate. Many factors, including genetic predisposition, may influence the pattern of the disease. People with rheumatoid arthritis may have a mild course, occasional flare-ups with long periods of remission without disease, or a steadily progressive disease, which may be slow or rapid. Rheumatoid arthritis may start suddenly, with many joints becoming inflamed at the same time. More often, it starts subtly, gradually affecting different joints. Usually, the inflammation is symmetric, with joints on both sides of the body affected. Typically, the small joints in the fingers, toes, hands, feet, wrists, elbows, and ankles become inflamed first, followed by the knees and hips.

Pain associated with rheumatoid arthritis is typically somatic nociceptive joint pain. Swollen wrists

Doses for compounds or salts of the invention range from 0.1 mg to 100 mg for oral administration and doses range from 2 mg or less for inhaled administration. The dose may be administered in single dose or two or more divided doses and may fall outside of the typical range given herein.

The dosages are based on an average human subject having a weight of about 60 kg to 70 kg. Dosing and dosing regimen depend upon subject and a variety of conditions that may affect dosing (age, sex, body weight, etc.). A physician or other medical professional will readily be able to determine doses for subjects whose weight falls outside this range, such as infants and the elderly. Oral Administration

The compounds of the invention and salts thereof may be administered orally. Oral administration may involve swallowing, so that the compound or salt enters the gastrointestinal tract, and/or buccal, lingual, or sublingual administration by which the compound or salt enters the blood stream directly from the mouth.

Formulations suitable for oral administration include solid, semi-solid and liquid systems such as tablets; soft or hard capsules containing multi- or nano-particulates, liquids, or powders; lozenges (including liquid-filled); chews; gels; fast dispersing dosage forms; films; ovules; sprays; and

calcium phosphate dihydrate. Tablets may also optionally comprise surface active agents, such as sodium lauryl sulfate and polysorbate 80, and glidants such as silicon dioxide and talc. When present, surface active agents may comprise from 0.2 weight % to 5 weight % of the tablet, and glidants may comprise from 0.2 weight % to 1 weight % of the tablet.

Tablets also generally contain lubricants such as magnesium stearate, calcium stearate, zinc stearate, sodium stearyl fumarate, and mixtures of magnesium stearate with sodium lauryl sulphate. Lubricants generally comprise from 0.25 weight % to 10 weight %, preferably from 0.5 weight % to 3 weight % of the tablet.

Other possible ingredients include anti-oxidants, colorants, flavoring agents, preservatives and taste-masking agents. Exemplary tablets contain up to about 80% drug, from about 10 weight % to about 90 weight % binder, from about 0 weight % to about 85 weight % diluent, from about 2 weight % to about 10 weight % disintegrant, and from about 0.25 weight % to about 10 weight % lubricant.

Solid formulations for oral administration may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.

Suitable modified release formulations for the purposes of the invention are described in US Patent No. 6,106,864. Details of other suitable release technologies such as high energy dispersions and osmotic and coated particles are to be found in Pharmaceutical Technology On-line, 25(2), 1-14, by

semi-solid, or thixotropic liquid for administration as an implanted depot providing modified release of the active compound. Examples of such formulations include drug-coated stents and semi-solids and suspensions comprising drug-loaded poly(dl-lactic-coglycolic)acid (PGLA) microspheres.

Topical Administration

The compounds or salts of the invention may also be administered topically, (intra )dermally, or transdermal^ to the skin or mucosa. Example 1 could be administered to the skin. Typical formulations for this purpose include gels, hydrogels, lotions, solutions, creams, ointments, dusting powders, dressings, foams, films, skin patches, wafers, implants, sponges, fibres, bandages and microemulsions. Liposomes may also be used. Typical carriers include alcohol, water, mineral oil, liquid petrolatum, white petrolatum, glycerin, polyethylene glycol and propylene glycol. Penetration enhancers may be incorporated - see, for example, J Pharm Sci, 88 (10), 955-958, by Finnin and Morgan (October 1999).

Other means of topical administration include delivery by electroporation, iontophoresis, phonophoresis, sonophoresis and microneedle or needle-free (e.g. Powderject™, Bioject™, etc.) injection.

Formulations for topical administration may be formulated to be immediate and/or modified release. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release.

A suitable solution formulation for use in an atomiser using electrohydrodynamics may comprise a compound of the present invention, propylene glycol, sterile water, ethanol and sodium chloride. Alternative solvents which may be used instead of propylene glycol include glycerol and polyethylene glycol.

Formulations for inhaled/intranasal administration may be formulated to be immediate and/or modified release using, for example, PGLA. Modified release formulations include delayed-, sustained-, pulsed-, controlled-, targeted and programmed release. In the case of dry powder inhalers and aerosols, the dosage unit is determined by means of a valve which delivers a metered amount. Units in accordance with the invention are typically arranged to administer a metered dose or "puff which may be administered in a single dose or, more usually, as divided doses throughout the day.

Dose ranges for inhaled administration range from 2 mg to less or 1 mg to less.

I. BIOLOGICAL DATA Lipopolysaccharide (LPS)-lnduced Human Whole Blood

Venous blood from human donors was collected as 10 ml aliquots in tubes containing sodium heparin (BD Vacutainer from Becton Dickinson and Company, Franklin Lakes, NY). Blood was added to sterile polystyrene round bottom 96-well tissue culture plates (Corning Costar) at 180 μl/well. Blood was placed in a humidified 37C incubator with 5% CO while compounds were prepared (nearly 60 minutes)

( , g p , , Sigma-Aldrich). Calibrators for standard curves were prepared in human plasma/serum assay diluent as a 1/5 serial dilution to achieve final concentrations ranging from 50000 pg/ml to 3.2 pg/ml. Samples were added at 10 to 20 μl/well and calibrators were added at 20 μl/well, then incubated at room temperature with gentle shaking for 2 hours. Plates were again washed 3x with wash buffer. Detection antibody was diluted in human plasma/serum antibody diluent to 1 μg/ml and added to the plate at 20 μl/well. Plates were incubated as before for 2 hours and washed again. Read Buffer T (4x) was diluted 1 :1 with mqH 2 O to 2x concentration and 150 μl added to each well. Plates were read on the SECTOR Imager 6000 (Meso Scale Discovery) to generate raw signal values. Individual sample signal values were compared to positive and negative controls (vehicle treated blood with LPS and vehicle treated blood without LPS, respectively) to generate % inhibition. Triplicate values were averaged for each donor. The values for three or four donors were averaged and graphed using A- parameter fit curves in the LabStats plug-in for the Microsoft Excel application.

Prednisolone was obtained from Sigma-Aldrich (Saint Louis, MO).

Comparator A is (4βS,7S,8αf?)-4β-benzyl-7-hydroxy-Λ/-((2-methylpyridin-3 -yl)methyl)-7-(3,3,3- trifluoropropyl)-4β,5,6,7,8,8α,9,10-octahydrophenanthrene- 2-carboxamide, the synthesis for which is described as Example No. 771 C-3 on page 241 of WO 00/66522 (Dow et al.), and has the following structure:

The following comparative compounds, Comparators B, C and D, can be prepared by methods described herein, those known in the art and Scheme D, below.

stimulated human whole blood. Prednisolone, a full agonist of GR, demonstrates full inhibition of IFN ,

TNF and IL-1 . Example 1 also inhibits cytokine release in a concentration-dependent manner. Being a partial agonist/antagonist, Example 1 does not show inhibition to the extent of prednisolone. Furthermore, the level of inhibition observed for Example 1 is different between cytokines measured,that is to say,. IFN =73%, TNF =43%, and IL-1 =38%. In contrast to Example 1 , Comparator F and Comparator G do not significantly inhibit TNF or IL-1 (less than 20% at 300OnM) and show a very much less efficacious inhibition of IFN (only 22% or 41 % inhibition at 3000 nM, respectively). Thus, while Example 1 , Comparator F, Comparator G and prednisolone bind to the same receptor, they demonstrate markedly different activities.

TNFa repression after a single ED 80 dose (determined from the acute LPS endotoxemia mouse model). In order to repress TNFa significantly over a 24 hour period, it was determined that prednisolone required b.i.d. dosing. DAGR compounds vary in their required frequency of doses.

Body weights are measured on the first and last day of each experiment. Blood samples are obtained after ~3 weeks of dosing for steady-state pharmacokinetic analysis. To assess compound effects on LPS-induced TNF-a, all mice receive an intraperitoneal injection of LPS (Salmonella Typhosa , Sigma, St. Louis, L-7895) 2.5 hr after the last dose on day 28. Mice are sacrificed 90 min. after LPS administration Serum samples are assayed for osteocalcin and TNFa using the Linco multiplex assay (St. Charles, MO) and Luminex 100 (Austin, TX). Samples are diluted 1 :20 and the assay is run according to manufacturer's instructions. An osteocalcin standard is purchased separately from Biomedical Technologies Incorporated (Stoughton, MA). Serum insulin is measured to assess compound effects on insulin resistance. Insulin was measured using the Ultrasensitive Mouse EIA kit from Alpco Diagnostics (Salem, NH) following the manufacturer's protocol.

Cortical Bone Histomorphometry

During the in-life portion of each study, mice received two IP injections of the fluorochrome calcein (C- 0875; Sigma-Aldrich; 20 mg/kg; 200 μL/mouse), dissolved in 2% sodium bicarbonate, on days 1 and 26 for bone histomorphometry measurements. Fluorochrome labels incorporate into the bone mineral and allow measurement of bone formation rate During the tissue harvest the left tibia is excised and cleaned

injection and 5μL was injected in the LC/MS/MS system for analysis. Concentrations below the limit of quantitation (LOQ) are reported as zero (0) and are used in the evaluation of mean concentrations and the estimation of AUC. The area under the concentration-time curve from time zero to time of the last quantifiable concentration (t) [AUC(O-t)] is determined using the linear trapezoidal method.

Statistical Evaluation

ED 50 and ED 80 values are obtained for the various parameters using four-parameter logistic fits of data. For each experiment/dose group, outliers are detected by calculating the number of standard deviations each mouse's value was from the mean of their group and then dividing by the standard deviation of the group. The means and standard deviations used in this calculation omitted the value being examined so that, if it were an outlier, it would have no influence. If the value being examined is more than 2.5 standard deviations from the mean, it was not used in the rest of the calculations.

Percent inhibition values are then calculated for each animal using the means of the vehicle and 10 mpk prednisone control groups. The individual mouse percent inhibition values are then fit to a four- parameter logistic model using the area under curve mean for each group. Since all four parameters are estimated and the lower plateau is not fixed at 0% and the upper plateau was not fixed at 100%, the ED 50 and ED 80 values are calculated by using an inverse calibration formula for a response equal to 50% or 80%. The designation "nd" means not determined.

effects. Dissociation indices were calculated using clinically relevant biomarkers that could be utilized in early clinical development. Serum osteocalcin and LPS-induced serum TNFα are accepted clinically as predictive for bone formation and anti-inflammatory efficacy, respectively. The dissociation index was based on the following tenets:

1) Dissociation required a dose-margin between biomarkers of inflammation and side-effects [such as osteocalcin (OC), insulin, or bone formation rate], and was defined by the formula, using osteocalcin suppression (OC) as the side effect example:

Dl = Side-effect endpoint

Anti-inflammatory endpoint

2) The Dl of a compound can be considered relative to that observed with prednisolone, its clinical comparator. The corrected or normalized Dl was defined as compound Dl divided by prednisolone Dl.
