BACKGROUND OF THE INVENTION Excessive weight, and in extreme cases obesity, is a widespread medical problem. This may be due in part to sedentary life styles and poor diet (high in fats and carbohydrates), as well as to a genetic predisposition in many cases.

Pharmaceuticals have been marketed in the past to help control excessive weight and obesity. These have typically tried to achieve weight loss by reducing appetite. Drugs used to reduce appetite have not been universally successful.

Many are stimulants and have been abused, and others have had unexpected, and sometimes serious side effects (e. g., fen-phen). An approach that has so far not been exploited successfully is the development of pharmaceuticals that control excessive weight and obesity using a metabolic approach by modulation of receptors that can influence weight gain.

Diabetes refers to a disease process derived from multiple causative factors and characterized by elevated levels of plasma glucose or hyperglycemia in the fasting state or after administration of glucose during an oral glucose tolerance test.

Persistent or uncontrolled hyperglycemia is associated with increased and premature morbidity and mortality. Often abnormal glucose homeostasis is associated both directly and indirectly with alterations of the lipid, lipoprotein and apolipoprotein metabolism and other metabolic and hemodynamic disease. Therefore patients with Type 2 diabetes mellitus are at especially increased risk of macrovascular and microvascular complications, including coronary heart disease, stroke, peripheral vascular disease, hypertension, nephropathy, neuropathy, and retinopathy. Therefore, therapeutical control of glucose homeostasis, lipid metabolism and hypertension are critically important in the clinical management and treatment of diabetes mellitus.

There are two generally recognized forms of diabetes. In type 1 diabetes, or insulin-dependent diabetes mellitus (IDDM), patients produce little or no insulin, the hormone which regulates glucose utilization. In type 2 diabetes, or noninsulin dependent diabetes mellitus (NIDDM), patients often have plasma insulin levels that are the same or even elevated compared to nondiabetic subjects; however, these patients have developed a resistance to the insulin stimulating effect on glucose and lipid metabolism in the main insulin-sensitive tissues, which are muscle, liver and adipose tissues, and the plasma insulin levels, while elevated, are insufficient to overcome the pronounced insulin resistance.

Insulin resistance is not primarily due to a diminished number of insulin receptors but to a post-insulin receptor binding defect that is not yet understood. This resistance to insulin responsiveness results in insufficient insulin activation of glucose uptake, oxidation and storage in muscle and inadequate insulin repression of lipolysis in adipose tissue and of glucose production and secretion in the liver.

The available treatments for type 2 diabetes have recognized limitations. While physical exercise and reductions in dietary intake of calories will dramatically improve the diabetic condition, compliance with this treatment is very poor because of well-entrenched sedentary lifestyles and excess food consumption, especially of foods containing high amounts of saturated fat. Increasing the plasma level of insulin by administration of sulfonylureas (e. g. tolbutamide and glipizide), which stimulate the pancreatic ß-cells to secrete more insulin, and/or by injection of insulin after the response to sulfonylureas fails, will result in high enough insulin concentrations to stimulate the very insulin-resistant tissues. However, dangerously low levels of plasma glucose can result from these last two treatments, and increasing insulin resistance due to the even higher plasma insulin levels can occur. The biguanides increase insulin sensitivity resulting in some correction of hyperglycemia.

However, the two biguanides, phenformin and metformin, can induce lactic acidosis and nausea/diarrhea, respectively.

The glitazones (i. e. 5-benzylthiazolidine-2,4-diones) are a more recently described class of compounds with potential for a novel mode of action in ameliorating many symptoms of type 2 diabetes. These agents substantially increase insulin sensitivity in muscle, liver and adipose tissue in several animal models of type 2 diabetes resulting in partial or complete correction of the elevated plasma levels of glucose without occurrence of hypoglycemia.

Disorders of lipid metabolism or dyslipidemias include various conditions characterized by abnormal concentrations of one or more lipids (i. e. cholesterol and triglycerides), and/or apolipoproteins (i. e., apolipoproteins A, B, C and E), and/or lipoproteins (i. e., the macromolecular complexes formed by the lipid and the apolipoprotein that allow lipids to circulate in blood, such as LDL, VLDL and IDL). Cholesterol is mostly carried in Low Density Lipoproteins (LDL), and this component is commonly known as the"bad"cholesterol because it has been shown that elevations in LDL-cholesterol correlate closely to the risk of coronary heart disease. A smaller component of cholesterol is carried in the High Density Lipoproteins and is commonly known as the"good"cholesterol. In fact, it is known that the primary function of HDL is to accept cholesterol deposited in the arterial wall and to transport it back to the liver for disposal through the intestine. Although it is desirable to lower elevated levels of LDL cholesterol, it is also desirable to increase levels of HDL cholesterol. Generally, it has been found that increased levels of HDL are associated with lower risk for coronary heart disease (CHD). See, for example, Gordon, et al., Am. J. Med., 62,707-714 (1977); Stampfer, et al., N. England J.

Med., 325, 373-381 (1991) ; and Kannel, et al., Ann. Internal Med., 90,85-91 (1979).

An example of an HDL raising agent is nicotinic acid, a drug with limited utility because doses that achieve HDL raising are associated with undesirable effects, such as flushing.

Dyslipidemias were originally classified by Fredrickson according to the combination of alterations mentioned above. The Fredrickson classification includes 6 phenotypes (i. e., I, Ha, nb, m, IV and V) with the most common being the isolated hypercholesterolemia (or type IIa) which is usually accompanied by elevated concentrations of total and LDL cholesterol. The initial treatment for hypercholesterolemia is often to modify the diet to one low in fat and cholesterol, coupled with appropriate physical exercise, followed by drug therapy when LDL- lowering goals are not met by diet and exercise alone A second common form of dyslipidemia is the mixed or combined hyperlipidemia or type IIb and m of the Fredrickson classification. This dyslipidemia is often prevalent in patients with type 2 diabetes, obesity and the metabolic syndrome. In this dyslipidemia there are modest elevations of LDL-cholesterol, accompanied by more pronounced elevations of small dense LDL-cholesterol particles, VLDL and/or IDL (i. e., triglyceride rich lipoproteins), and total triglycerides. In addition, concentrations of HDL are often low.

Peroxisome proliferator activated receptors (PPARs) have attracted considerable scientific attention in the last few years in part because of their emergence as the molecular target of a new group of Type II (non-insulin dependent) diabetes (NIDDM) medicines, the glitazones. Three sub-types of peroxisome proliferator activated receptor (PPAR) have been discovered and described; they are peroxisome proliferator activated receptor gamma (PPARy), peroxisome proliferator activated receptor alpha (PPARoc) and peroxisome proliferator activated receptor delta (PPAR8).

The PPARy receptor subtypes are involved in activating the program of adipocyte differentiation and are not involved in stimulating peroxisome proliferation in the liver. There are two known protein isoforms of PPARy : PPARyl and PPARy2 which differ only in that PPARy2 contains an additional 28 amino acids present at the amino terminus. The DNA sequences for the human isotypes are described in Elbrecht, et al., BBRC 224; 431-437 (1996). In mice, PPARy2 is expressed specifically in fat cells. Tontonoz et al., Cell 79: 1147-1156 (1994) provide evidence to show that one physiological role of PPARy2 is to induce adipocyte differentiation.

As with other members of the nuclear hormone receptor superfamily, PPARy2 regulates the expression of genes through interaction with other proteins and binding to hormone response elements, for example in the 5'flanking regions of responsive genes. An example of a PPARy2 responsive gene is the tissue-specific adipocyte P2 gene. Although peroxisome proliferators, including the fibrates and fatty acids, activate the transcriptional activity of PPAR's, only prostaglandin J2 derivatives have been identified as potential natural ligands of the PPARy subtype, which also binds thiazolidinedione antidiabetic agents with high affinity.

It is generally believed that glitazones exert their effects by binding to the peroxisome proliferator activated receptor (PPAR) family of receptors, controlling certain transcription elements having to do with the biological entities listed above.

See Hulin et al., Current Pharm. Design (1996) 2,85-102. A number of glitazones that are PPAR agonists have been approved for use in the treatment of diabetes. These include troglitazone, rosiglitazone and pioglitazone, all of which are primarily or exclusively PPARy agonists. Many of the newer PPAR agonists that are currently under development or are in clinical trials have dual PPARoc and y activity. These are expected to improve both insulin sensitivity and the lipid profile in patients having NIDDM. Although glitazones are beneficial in the treatment of NIDDM, there have been some serious adverse events associated with the use of the compounds. The

most serious of these has been liver toxicity, which has resulted in a number of deaths.

The most serious problems have occurred using troglitazone. Because of the problems that have occurred with the glitazones, researchers in a number of laboratories have been investigating classes of PPAR agonists that are not glitazones and do not contain 1,3-thiazolidinedione moieties. In addition some ligands behave as partial agonists of PPARy. There are some reasons to believe that such compounds might exhibit modulated pharmacology. As such there has been growing interest in such compounds.

Several patent applications and publications have suggested that PPAR-gamma antagonists or partial agonists may be effective in the treatment of obesity. See WO 96/40128, WO 97/10813, and J. Oberfield, et al., Proc. Nat. Acad.

Sci. USA, Vol. 96, pp 6102-6106 (1999). Also, since PPAR-gamma agonists are used in the treatment of NIDDM, and obesity generally accompanies NIDDM, these compounds are generally also claimed as useful in the treatment of obesity.

PPAR (X is activated by a number of medium and long-chain fatty acids, and it is involved in stimulating ß-oxidation of fatty acids. PPARa is also associated with the activity of fibrates and fatty acids in rodents and humans. Fibric acid derivatives such as clofibrate, fenofibrate, bezafibrate, ciprofibrate, beclofibrate and etofibrate, as well as gemfibrozil, each of which are PPARoc ligands and/or activators, produce a substantial reduction in plasma triglycerides as well as some increase in HDL. The effects on LDL cholesterol are inconsistent and might depend upon the compound and/or the dyslipidemic phenotype. For these reasons, this class of compounds has been primarily used to treat hypertriglyceridemia (i. e, Fredrickson Type IV and V) and/or mixed hyperlipidemia. It is important to note that there may exist a degree of overlap between the functions of PPARy and PPARa.

The human nuclear receptor gene PPAR8 (hPPARB) has been cloned from a human osteosarcoma cell cDNA library and is fully described in A. Schmidt et al., Molecular Endocrnology, 6 : 1634-1641 (1992). It should be noted that PPAR8 is also referred to in the literature as PPARß and as Nl JC1, and each of these names refers to the same receptor; in Schmidt et al. the receptor is referred to as NUC1. In W096/01430, a human PPAR subtype, hNUClB, is disclosed. The amino acid sequence of hNUClB differs from human PEAR8 (referred to therein as hNUC1) by one amino acid, i. e., alanine at position 292. Based on in vivo experiments described therein, the authors suggest that hNUClB protein represses hPPARoc and thyroid hormone receptor protein activity. It has been disclosed in W097/28149 that agonists

of PPAR8 are useful in raising HDL plasma levels. W097/27857, 97/28115, 97/28137 and 97/27847 disclose compounds that are useful as antidiabetic, antiobesity, anti-atherosclerosis and antihyperlipidemic agents, and which may exert their effect through activation of PPARs.

SUMMARY OF THE INVENTION The class of compounds described herein is a new class of PPAR ligands that do not contain a 1,3-thiazolidinedione moiety and therefore are not glitazones. The compounds in this class are primarily PPARy antagonists or partial agonists. Some of the compounds may also exhibit some level of PPARa agonism.

These compounds are useful in the treatment, control and/or prevention of obesity, diabetes, hyperglycemia, insulin resistance, mixed or diabetic dyslipidemia, other lipid disorders, atherosclerosis, vascular restenosis, inflammatory conditions, neoplastic conditions, and other PPARy mediated diseases, disorders and conditions.

If desired, racemic mixtures of compounds of Formula I may be separated by the coupling of a racemic mixture of the compounds of Formula I to an enantiomerically pure compound to form a diastereomeric mixture, followed by separation of the individual diastereomers by standard methods, such as fractional crystallization or chromatography. The coupling reaction is often the formation of salts using an enantiomerically pure acid or base. The diasteromeric derivatives may then be converted to the pure enantiomers by cleavage of the added chiral residue.

The racemic mixture of the compounds of Formula I can also be separated directly by chromatographic methods utilizing chiral stationary phases, which methods are well known in the art.

Alternatively, any enantiomer of a compound of the general Formula I may be obtained by stereoselective synthesis using optically pure starting materials or reagents of known configuration. Such methods are well known in the art.

Compounds of Formula I that have more than one asymmetric center and that occur as mixtures of diasteromers can similarly be separated into single diasteromers by standard methods, and these can be further separated to individual enantiomers as described above.

Administration and Dose Ranges Any suitable route of administration may be employed for providing a mammal, especially a human, with an effective dose of a compound of the present invention. For example, oral, rectal, topical, parenteral, ocular, pulmonary, nasal, and the like may be employed. Dosage forms include tablets, troches, dispersions, suspensions, solutions, capsules, creams, ointments, aerosols, and the like. Preferably compounds of Formula I are administered orally.

The effective dosage of active ingredient employed may vary depending on the particular compound employed, the mode of administration, the condition being treated and the severity of the condition being treated. Such dosage may be ascertained readily by a person skilled in the art.

When treating or preventing obesity, diabetes mellitus and/or hyperglycemia or hypertriglyceridemia or other diseases for which compounds of Formula I are indicated, generally satisfactory results are obtained when the

compounds of the present invention are administered at a daily dosage of from about 0.1 milligram to about 100 milligram per kilogram of animal body weight, preferably given as a single daily dose or in divided doses two to six times a day, or in sustained release form. For most large mammals, the total daily dosage is from about 1.0 milligrams to about 1000 milligrams, preferably from about 1 milligrams to about 50 milligrams. In the case of a 70 kg adult human, the total daily dose will generally be from about 7 milligrams to about 350 milligrams. This dosage regimen may be adjusted to provide the optimal therapeutic response.

Pharmaceutical Compositions Another aspect of the present invention provides pharmaceutical compositions which comprise a compound of Formula I and a pharmaceutically acceptable carrier. The pharmaceutical compositions of the present invention comprise a compound of Formula I or a pharmaceutically acceptable salt or prodrug thereof as an active ingredient, as well as a pharmaceutically acceptable carrier and optionally other therapeutic ingredients. The term"pharmaceutically acceptable salts" refers to salts prepared from pharmaceutically acceptable non-toxic bases or acids including inorganic bases or acids and organic bases or acids.

The compositions include compositions suitable for oral, rectal, topical, parenteral (including subcutaneous, intramuscular, and intravenous), ocular (ophthalmic), pulmonary (nasal or buccal inhalation), or nasal administration, although the most suitable route in any given case will depend on the nature and severity of the conditions being treated and on the nature of the active ingredient.

They may be conveniently presented in unit dosage form and prepared by any of the methods well-known in the art of pharmacy.

In practical use, the compounds of Formula I can be combined as the active ingredient in intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e. g., oral or parenteral (including intravenous). In preparing the compositions for oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents and the like in the case of oral liquid preparations, such as, for example, suspensions, elixirs and solutions; or carriers such as starches, sugars, microcrystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents and the like in

the case of oral solid preparations such as, for example, powders, hard and soft capsules and tablets, with the solid oral preparations being preferred over the liquid preparations.

Because of their ease of administration, tablets and capsules represent the most advantageous oral dosage unit form in which case solid pharmaceutical carriers are obviously employed. If desired, tablets may be coated by standard aqueous or nonaqueous techniques. Such compositions and preparations should contain at least 0.1 percent of active compound. The percentage of active compound in these compositions may, of course, be varied and may conveniently be between about 2 percent to about 60 percent of the weight of the unit. The amount of active compound in such therapeutically useful compositions is such that an effective dosage will be obtained. The active compounds can also be administered intranasally as, for example, liquid drops or spray.

The tablets, pills, capsules, and the like may also contain a binder such as gum tragacanth, acacia, corn starch or gelatin; excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid; a lubricant such as magnesium stearate; and a sweetening agent such as sucrose, lactose or saccharin. When a dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier such as a fatty oil.

Various other materials may be present as coatings or to modify the physical form of the dosage unit. For instance, tablets may be coated with shellac, sugar or both. A syrup or elixir may contain, in addition to the active ingredient, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye and a flavoring such as cherry or orange flavor.

Compounds of formula I may also be administered parenterally.

Solutions or suspensions of these active compounds can be prepared in water suitably mixed with a surfactant such as hydroxy-propylcellulose. Dispersions can also be prepared in glycerol, liquid polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.

The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against

the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e. g. glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils.

Combination Therapy Compounds of Formula I may be used in combination with other drugs that may also be useful in the treatment, prevention, suppression or amelioration of the diseases or conditions for which compounds of Formula I are useful. Such other drugs may be administered, by a route and in an amount commonly used therefor, contemporaneously or sequentially with a compound of Formula I. When a compound of Formula I is used contemporaneously with one or more other drugs, a pharmaceutical composition in unit dosage form containing such other drugs and the compound of Formula I is preferred. However, the combination therapy also includes therapies in which the compound of Formula I and one or more other drugs are administered on different overlapping schedules. It is also contemplated that when used in combination with one or more other active ingredients, the compound of the present invention and the other active ingredients may be used in lower doses than when each is used singly. Accordingly, the pharmaceutical compositions of the present invention include those that contain one or more other active ingredients, in addition to a compound of Formula I.

Examples of other active ingredients that may be administered in combination with a compound of Formula I, and either administered separately or in the same pharmaceutical composition, include, but are not limited to: (a) insulin sensitizers including (i) PPARy agonists such as the glitazones (e. g. troglitazone, pioglitazone, englitazone, MCC-555, rosiglitazone, and the like), and compounds disclosed in W097/27857,97/28115,97/28137 and 97/27847; (ii) biguanides such as metformin and phenformin ; (iii) protein tyrosine phosphatase-lB (PTP-1B) inhibitors, and (iv) dipeptidyl peptidase IV (DP-IV) inhibitors; (b) insulin or insulin mimetics; (c) sulfonylureas such as tolbutamide and glipizide, or related materials; (d) a-glucosidase inhibitors (such as acarbose);

Unbound ligand was removed by incubation with 100 AL dextran/gelatin-coated charcoal, on ice, for-10 min. After centrifugation at 3000 rpm for 10 min at 4°C, 50 juL of the supernatant fraction was counted in a Topcount.

B). Gal-4 hPPAR Transactivation Assays The chimeric receptor expression constructs, pcDNA3-hPPARy/GAL4, pcDNA3-hPPAR6/GALA, pcDNA3-hPPARo ! IGAL4 were prepared by inserting the yeast GAL4 transcription factor DBD adjacent to the ligand binding domains (LBDs) of hPPARy, hPPARS, hPPARa, respectively. The reporter construct, pUAS (5X)-tk- luc was generated by inserting 5 copies of the GAL4 response element upstream of the herpes virus minimal thymidine kinase promoter and the luciferase reporter gene. pCMV-lacZ contains the galactosidase Z gene under the regulation of the cytomegalovirus promoter. COS-1 cells were seeded at 12 X 10 cells/well in 96 well cell culture plates in high glucose Dulbecco's modified Eagle medium (DMEM) containing 10% charcoal stripped fetal calf serum (Gemini Bio-Products, Calabasas, CA), nonessential amino acids, 100 units/ml Penicillin G and 100 mg/ml Streptomycin sulfate at 37 °C in a humidified atmosphere of 10% C02. After 24 h, transfections were performed with Lipofectamine (GIBCO BRL, Gaithersburg, MD) according to the instructions of the manufacturer. Briefly, transfection mixes for each well contained 0.48 Ill of Lipofectamine, 0.00075 jg ofpcDNA3-PPAR/GAL4 expression vector, 0.045 p, g of pUAS (5X)-tk-luc reporter vector and 0.0002, ug of pCMV-lacZ as an internal control for transactivation efficiency. Cells were incubated in the transfection mixture for 5 h at 37° C in an atmosphere of 10% CO2. The cells were then incubated for-48 h in fresh high glucose DMEM containing 5% charcoal stripped fetal calf serum, nonessential amino acids, 100 units/ml Penicillin G and 100 mg/ml Streptomycin sulfate increasing concentrations of test compound. Since the compounds were solubilized in DMSO, control cells were incubated with equivalent concentrations of DMSO; final DMSO concentrations were < 0. 1%, a concentration which was shown not to effect transactivation activity. Cell lysates were produced using Reporter Lysis Buffer (Promega, Madison, WI) according to the manufacturer's instructions. Luciferase activity in cell extracts was determined using Luciferase Assay Buffer (Promega, Madison, WI) in an ML3000 luminometer (Dynatech Laboratories, Chantilly, VA). (3-galactosidase activity was determined using P-D- galactopyranoside (Calbiochem, San Diego, CA).

Measurement of Antagonism/Partial Agonis Antagonists and partial agonists are well known in the art. The above assays can be used to measure the PPARy antagonism/partial agonism of the compounds disclosed herein or of other compounds by measuring the PPARy agonism of a"full"agonist and then measuring the inhibition (usually as a % inhibition) of the full PPARy agonist when a sample of the compound being tested is also included in the assay. A full agonist is a PPARy agonist that is known to be very effective in comparison with other PPARy agonists. Examples of full agonists include rosiglitazone, pioglitazone and 3-tchloro-4-(3-(3-phenyl-7-propylbenzofuran-6- yloxy) propylthio) phenylacetic acid (described by Berger et al, Journal of Biological Chemistry Vol 274,6718-6725,1999). The synthesis of 3-chloro-4- (3- (3-phenyl-7- propylbenzofuran-6-yloxy) propylthio) phenylacetic acid is disclosed in US Patent No.

5,859,051.

Compounds that are PPARy antagonists or partial agonists and that may be useful in treating obesity and possibly other conditions that are modulated by PPARy are expected to inhibit the PPARy agonism of a full PPARy agonist to a level of less than 50% of its normal level of agonism using the GAL4 chimeric receptor transcriptional assay, and possibly less than 25% of its normal level of agonism.

A second assay method that can also be used is the PPAR-CBP HTRF assay, described by Zhou, et al, Molecular Endocrinology, Vol. 12,1594-1604 (1998), which reference is incorporated herein by reference. A third assay method that can be used is the 3T3-L1 pre-adipocyte differentiation assay, described by Berger et al, Journal of Biological Chemistry, Vol 274,6718-6725 (1999). These assays are summarized below.

PPAR-CBP HTRF Assay Briefly, 100 mM HEPES, 123mM KF, 0.125% (wt/vol) CHAPS, 0.05% dry milk, 1 nM GST-PPARyLBD, 2 nM anti-GST- (Eu) K, 10 nM biotin-CBPI 453, 20 nM SA/XL665, a potent PPARy agonist, and the compound being tested (100 nM) at several concentrations are incubated overnight at 4° C.

Fluorescence is then read on a Discovery instrument (Packard). Data are expressed as the ratio, multiplied by a factor of 104, of the emission intensity at 665 nM to that at 620 nM.

3T3-L1 Preadipocyte Differentiation Assay 3T3-L1 cells are obtained from American Type Culture Collection.

Passage numbers 3 to 9 are used. Monolayer fibroblasts are maintained in medium A (Dulbecco's modified Eagle's medium with 10% fetal calf serum, 100 units/ml penicillin, and 100 yg/ml streptomycin) at 37 °C in 5% C02. For experiments, the cells are incubated with medium A (supplemented with 150 nM insulin, 1, uM dexamethasone) in the presence of 100 nM rosiglitazone and various concentrations of test compound for 5 days (with one medium change). Total RNA is prepared using UltraspecTM RNA isolation system (Biotecx, Houston, TX). RNA concentration is quantitated by absorbance at 260 nm. Equal amounts of RNA samples are denatured in formamide/formaldehyde and applied to HybondTM-N membranes (Amersham) using a slot blot apparatus (BioRad). Prehybridization is performed at 42C for 1-3 h in 40-50% formamide in a solution containing 25 mM sodium phosphate, pH 7.4,0.9 M sodium chloride, 50 mM sodium citrate, 0.1% each of gelatin, ficoll, and polyvinylpyrollidone, 0.5 % SDS, and 100 yg/ml denatured salmon sperm DNA.

Hybridization is carried out at the same temperature for 20h in the same solution with 32P-labeled aP2 cDNA probe (2 x 106 cpm/ml). After washing the membranes under appropriately stringent conditions, the hybridization signals are analyzed with a Phosphorlmager (Molecular Dynamics).
