TECHNICAL FIELD
This invention relates generally to cinnoline-based modulators of Liver X receptors (LXRs) and related methods.
BACKGROUND
Atherosclerosis is among the leading causes of death in developed countries. Some of the independent risk factors associated with atherosclerosis include the presence of relatively high levels of serum LDL cholesterol and relatively low levels of serum HDL cholesterol in affected patients. As such, some anti-atherosclerotic therapy regimens include the administration of agents (e.g., statins) to reduce elevated serum LDL cholesterol levels.
Agents that increase patient HDL cholesterol levels can also be useful in anti-atherosclerotic therapy regimens. HDL cholesterol is believed to play a major role in the transport of cholesterol from peripheral tissues to the liver for metabolism and excretion (this process is sometimes referred to as “reverse cholesterol transport”). ABCA1 is a transporter gene involved in HDL production and reverse cholesterol transport. Upregulation of ABCA1 can therefore result in increased reverse cholesterol transport as well as inhibition of cholesterol absorption in the gut. In addition, HDL is also believed to inhibit the oxidation of LDL cholesterol, reduce the inflammatory response of endothelial cells, inhibit the coagulation pathway, and promote the availability of nitric oxide.
Liver X receptors (LXRs), originally identified in the liver as orphan receptors, are members of the nuclear hormone receptor super family and are believed to be involved in the regulation of cholesterol and lipid metabolism. LXRs are ligand-activated transcription factors and bind to DNA as obligate heterodimers with retinoid X receptors. While LXRα is generally found in tissues such as liver, kidney, adipose tissue, intestine and macrophages, LXRβ displays a ubiquitous tissue distribution pattern. Activation of LXRs by oxysterols (endogenous ligands) in macrophages results in the expression of several genes involved in lipid metabolism and reverse cholesterol transport including the aforementioned ABCA1; ABCG1; and ApoE.
Studies have been conducted in LXRα knock-out (k/o), LXRβ k/o and double k/o mice to determine the physiological role of LXRs in lipid homeostasis and atherosclerosis. The data from these studies suggested that in double k/o mice on normal chow diet, increased cholesterol accumulation was observed in macrophages (foam cells) of the spleen, lung and arterial wall. The increased cholesterol accumulation was believed to be associated with the presence of reduced serum HDL cholesterol and increased LDL cholesterol, even though the total cholesterol levels in the mice were about normal. While LXRα k/o mice did not appear to show significant changes in hepatic gene expression, LXRβ k/o mice showed 58% decrease in hepatic ABCA1 expression and 208% increase in SREBP1c expression suggesting that LXRβ may be involved in the regulation of liver SREBP1c expression.
Data obtained from studies employing two different atherosclerotic mouse models (ApoE k/o and LDLR k/o) suggest that agonists of LXRα or β can be relatively effective in upregulating ABCA1 expression in macrophages. For example, inhibition of atherosclerotic lesions could be observed when ApoE k/o and LDLR k/o mice were treated with LXRα or β agonists for 12 weeks. The tested agonists were observed to have variable effects on serum cholesterol and lipoprotein levels and appeared to cause a relatively significant increase in serum HDL cholesterol and triglyceride levels. These in vivo data were found to be consistent with in vitro data obtained for the same agonists in macrophages.
In addition to the lipid and triglyceride effects described above, it is also believed that activation of LXRs results in the inhibition of inflammation and proinflammatory gene expression. This hypothesis is based on data obtained from studies employing three different models of inflammation (LPS-induced sepsis, acute contact dermatitis of the ear and chronic atherosclerotic inflammation of the artery wall). These data suggest that LXR modulators can mediate both the removal of cholesterol from the macrophages and the inhibition of vascular inflammation.

It is understood that the actual electronic structure of some chemical entities cannot be adequately represented by only one canonical form (i.e. Lewis structure). While not wishing to be bound by theory, the actual structure can instead be some hybrid or weighted average of two or more canonical forms, known collectively as resonance forms or structures. Resonance structures are not discrete chemical entities and exist only on paper. They differ from one another only in the placement or “localization” of the bonding and nonbonding electrons for a particular chemical entity. It can be possible for one resonance structure to contribute to a greater extent to the hybrid than the others. Thus, the written and graphical descriptions of the embodiments of the present invention are made in terms of what the art recognizes as the predominant resonance form for a particular species.
The compounds described herein can be synthesized according to methods described herein and/or conventional, organic chemical synthesis methods from commercially available starting materials and reagents. The compounds described herein can be separated from a reaction mixture and further purified by a method such as column chromatography, high-pressure liquid chromatography, or recrystallization. As can be appreciated by the skilled artisan, further methods of synthesizing the compounds of the formulae herein will be evident to those of ordinary skill in the art. Additionally, the various synthetic steps may be performed in an alternate sequence or order to give the desired compounds. Synthetic chemistry transformations and protecting group methodologies (protection and deprotection) useful in synthesizing the compounds described herein are known in the art and include, for example, those such as described in R. Larock, Comprehensive Organic Transformations, VCH Publishers (1989); T. W. Greene and P. G. M. Wuts, Protective Groups in Organic Synthesis, 2d. Ed., John Wiley and Sons (1991); L. Fieser and M.

Reaction of the amide 2 with a lithio or Grignard reagent of formula R2Li or R2MgBr at low temperature can provide the ketone 3. Conversion of the ketone 3 into the aniline 4 can be accomplished with ammonium hydroxide at elevated temperature. Intermediate 5 is prepared by reacting 4 with R1XCH2MgBr followed by dehydration, which typically can occur spontaneously. Cinnoline 6 (X=bond) can be prepared via diazotisation (e.g., NaNO2/HCl) of the O-aminoaryl-ethylene 5 followed by a cyclization.




In some embodiments, cinnoline compounds having R1=R2 (i.e., the substituent corresponding to R1 in formula (I) is the same as the substituent corresponding to R1 in formula (I)) can be prepared, e.g., according to Scheme 2. The hydrazine compound 7 can be condensed with 1,2-diaryl-ethane-1,2-dione using conventional procedures to give hydrazone 8. Acid-mediated (e.g., H2SO4) cyclization of the hydrazone 8 can provide cinnoline 9.




In some embodiments, the cinnoline compounds of formula (I) can also be prepared according to Scheme 3. The 4-hydroxy cinnoline 12 can be synthesized in two steps by Friedel-Crafts acylation of the aniline 10 followed by ring closure under the diazotisation conditions. Conversion to 13 can be effected with conventional halogenating agents, e.g., POBr3 or SOCl2. Reaction of 13 with a boronic acid reagent of formula R2B(OH)2 in the presence of a palladium catalyst can provide 14.




In some embodiments, cinnoline compounds having an amino-substituted aryl group as the substituent corresponding to R2 in formula (I) can be prepared according to Scheme 4. Treatment of the free amine 15 with a sulfonyl chloride, an acid chloride or an isocyanate can provide compound 16, in which Y can be SO2, CO, or CONH, and A can be, e.g. aryl (e.g., phenyl) (X=bond).




In some embodiments, compounds of formula (I) can be prepared according to Scheme 5. Treatment of the free amine 17, wherein j is 0 ̃3, with an aldehyde (A-CHO) and a reducing agent such as NaBH(OAc)3, can result in the secondary amine 18. Alternatively, the secondary amine 18 can also be obtained upon treating the starting primary amine 17 with an alkylating agent (e.g., A-X′) in the presence of a base. If the A group of the compound of formula (I) contains a carboxylic acid ester moiety this moiety can be transformed to the carboxylic acid upon treatment with aqueous lithium, sodium or potassium hydroxide in water mixed with a suitable organic solvent (X=bond).




In some embodiments, compounds of formula (I) can be prepared according to Scheme 6. Alkylation of the hydroxy group of 19 with an alkylating agent (e.g., A-X′) using potassium carbonate as the base can provide the alkylated compound 200 is 0-3). Alternatively, if j is 1 or more and A-OH is a phenol or substituted phenol, or, j is 0 and A-OH is an alcohol where the OH is connected to an sp3 hybridized carbon, then the alcohol of formula 19 and the A-OH can be reacted with triphenylphosphine (PPh3) and diisopropylazodicarboxylate (DIAD) to form the ether of formula 20. If the A group of the compound of formula (I) contains a carboxylic acid ester moiety this moiety can be transformed to the carboxylic acid upon treatment with aqueous lithium, sodium or potassium hydroxide in a suitable organic solvent.




In some embodiments, the cinnoline compounds of formula (I) can also be prepared according to Scheme 7. The 4-hydroxy cinnoline 23 can be synthesized in two steps by Grignard reagent addition to the amide 21 followed by ring closure under the diazotisation conditions. Conversion to 24 can be effected with conventional halogenating agents, e.g., POBr3 or SOCl2. Reaction of 24 with a boronic acid reagent of formula R2B(OH)2 in the presence of a palladium catalyst can provide 25.

In general, the compounds described herein can be used for treating, controlling, ameliorating, preventing, delaying the onset of, or reducing the risk of developing one or more diseases, disorders, conditions or symptoms mediated by LXRs (e.g., cardiovascular diseases (e.g., acute coronary syndrome, restenosis), atherosclerosis, atherosclerotic lesions, type I diabetes, type II diabetes, Syndrome X, obesity, lipid disorders (e.g., dyslipidemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, low HDL and high LDL), cognitive disorders (e.g., Alzheimer's disease, dementia), inflammatory diseases (e.g., multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, Crohn's disease, endometriosis, LPS-induced sepsis, acute contact dermatitis of the ear, chronic atherosclerotic inflammation of the artery wall), celiac, or thyroiditis)). A disorder or physiological condition that is mediated by LXR refers to a disorder or condition wherein LXR can trigger the onset of the condition, or where inhibition of a particular LXR can affect signaling in such a way so as to treat, control, ameliorate, prevent, delay the onset of, or reduce the risk of developing the disorder or condition. Examples of such disorders include, but are not limited to cardiovascular diseases (e.g., acute coronary syndrome, restenosis), atherosclerosis, atherosclerotic lesions, type I diabetes, type II diabetes, Syndrome X, obesity, lipid disorders (e.g., dyslipidemia, hyperlipidemia, hypertriglyceridemia, hypercholesterolemia, low HDL and high LDL), cognitive disorders (e.g., Alzheimer's disease, dementia), inflammatory diseases (e.g., multiple sclerosis, rheumatoid arthritis, inflammatory bowel disease, Crohn's disease, endometriosis, LPS-induced sepsis, acute contact dermatitis of the ear, chronic atherosclerotic inflammation of the artery wall), celiac, or thyroiditis).
While not wishing to be bound by theory, it is believed that LXR modulators that activate cholesterol efflux (e.g., upregulate ABCA1), but do not substantially increase SREBP-1c expression and triglyceride synthesis in liver, can both reduce atherosclerotic risk and minimize the likelihood of concommitantly increasing serum and hepatic triglyceride levels. Candidate compounds having differential activity for regulating ABCA1 (ABCG1) vs. SREBP-1c can be can be evaluated using conventional pharmacological test procedures, which measure the affinity of a candidate compound to bind to LXR and to upregulate the gene ABCA1.
In some embodiments, LXR ligands can be identified initially in cell-free LXR beta and LXR alpha competition binding assays. LXR ligands can be further characterized by gene expression profiling for tissue selective gene regulation.
In some embodiments, the compounds described herein have agonist activity for ABCA1 transactivation but do not substantially affect (e.g., inhibit) SREBP-1c gene expression in differentiated THP-1 macrophages. Gene expression analysis in an antagonist mode can be used to further delineate differential regulation of ABCA1 and SREBP-1c gene expression. In certain embodiments, the compounds described herein preferentially antagonize SREBP-1c activation (a marker for genes involved in cholesterol and fatty acid homeostasis) but do not substantially affect (e.g., have relatively minimal or additive effects) on ABCA1 gene expression or genes known to enhance HDL biogenesis (based on a competition assay with known potent synthetic LXR agonists). Cell type or tissue specificity may be further evaluated in additional cell lines, intestinal, CaCo2 or liver, HepG2 and Huh-7 cells where ABCA1 activity is believed to influence net cholesterol absorption and reverse cholesterol transport. The test procedures performed, and results obtained therefrom are described in the Examples section.
In some embodiments, the compounds described herein have agonist activity for ABCA1 and antagonist activity for SREBP-1c (e.g., as determined by gene specific modulation in cell based assays). In certain embodiments, the compounds described herein (in the agonist mode) have at least about 20% efficacy for ABCA1 activation by LXR and do not substantially agonize SREBP-1c (at most about 25% efficacy relative to a reference compound N-(2,2,2-trifluoro-ethyl)-N-[4-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-phenyl]-benzenesulfonamide (Schultz, Joshua R., Genes & Development (2000), 14(22), 2831-2838)). In certain embodiments, the compounds described herein (in the antagonist mode) do not substantially antagonize ABCA1 gene expression. While not wishing to be bound by theory, it is believed that there may be an additive effect on ABCA1 gene expression relative to the reference compound at their EC50 concentration. In certain embodiments, the compounds described herein (in the antagonist mode) inhibited agonist-mediated SREBP-1c gene expression in a dose dependent fashion.
In some embodiments, the compounds described herein can be coadministered with one or more other threapeutic agents. In certain embodiments, the additional agents may be administered separately, as part of a multiple dose regimen, from the compounds of this invention (e.g., sequentially, e.g., on different overlapping schedules with the administration of one or more compounds of formula (I), (V) or (VI)). Alternatively, these agents may be part of a single dosage form, mixed together with the compounds of this invention in a single composition. In still another embodiment, these agents can be given as a separate dose that is administered at about the same time that one or more compounds of formula (I), (V) or (VI) are administered (e.g., simultaneously with the administration of one or more compounds of formula (I), (V) or (VI)). When the compositions of this invention comprise a combination of a compound of the formulae described herein and one or more additional therapeutic or prophylactic agents, both the compound and the additional agent should be present at dosage levels of between about 1 to 100%, and more preferably between about 5 to 95% of the dosage normally administered in a monotherapy regimen.
The compounds and compositions described herein can, for example, be administered orally, parenterally (e.g., subcutaneously, intracutaneously, intravenously, intramuscularly, intraarticularly, intraarterially, intrasynovially, intrasternally, intrathecally, intralesionally and by intracranial injection or infusion techniques), by inhalation spray, topically, rectally, nasally, buccally, vaginally, via an implanted reservoir, by injection, subdermally, intraperitoneally, transmucosally, or in an ophthalmic preparation, with a dosage ranging from about 0.01 mg/Kg to about 1000 mg/Kg, (e.g., from about 0.01 to about 100 mg/kg, from about 0.1 to about 100 mg/Kg, from about 1 to about 100 mg/Kg, from about 1 to about 10 mg/kg) every 4 to 120 hours, or according to the requirements of the particular drug. The interrelationship of dosages for animals and humans (based on milligrams per meter squared of body surface) is described by Freireich et al., Cancer Chemother. Rep. 50, 219 (1966). Body surface area may be approximately determined from height and weight of the patient. See, e.g., Scientific Tables, Geigy Pharmaceuticals, Ardsley, N.Y., 537 (1970). In certain embodiments, the compositions are administered by oral administration or administration by injection. The methods herein contemplate administration of an effective amount of compound or compound composition to achieve the desired or stated effect. Typically, the pharmaceutical compositions of this invention will be administered from about 1 to about 6 times per day or alternatively, as a continuous infusion. Such administration can be used as a chronic or acute therapy. The amount of active ingredient that may be combined with the carrier materials to produce a single dosage form will vary depending upon the host treated and the particular mode of administration. A typical preparation will contain from about 5% to about 95% active compound (w/w). Alternatively, such preparations contain from about 20% to about 80% active compound.
Lower or higher doses than those recited above may be required. Specific dosage and treatment regimens for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health status, sex, diet, time of administration, rate of excretion, drug combination, the severity and course of the disease, condition or symptoms, the patient's disposition to the disease, condition or symptoms, and the judgment of the treating physician.
Upon improvement of a patient's condition, a maintenance dose of a compound, composition or combination of this invention may be administered, if necessary. Subsequently, the dosage or frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved condition is retained when the symptoms have been alleviated to the desired level. Patients may, however, require intermittent treatment on a long-term basis upon any recurrence of disease symptoms.
The compositions of this invention may contain any conventional non-toxic pharmaceutically-acceptable carriers, adjuvants or vehicles. In some cases, the pH of the formulation may be adjusted with pharmaceutically acceptable acids, bases or buffers to enhance the stability of the formulated compound or its delivery form.
The compositions may be in the form of a sterile injectable preparation, for example, as a sterile injectable aqueous or oleaginous suspension. This suspension may be formulated according to techniques known in the art using suitable dispersing or wetting agents (such as, for example, Tween 80) and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are mannitol, water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives are useful in the preparation of injectables, as are natural pharmaceutically-acceptable oils, such as olive oil or castor oil, especially in their polyoxyethylated versions. These oil solutions or suspensions may also contain a long-chain alcohol diluent or dispersant, or carboxymethyl cellulose or similar dispersing agents which are commonly used in the formulation of pharmaceutically acceptable dosage forms such as emulsions and or suspensions. Other commonly used surfactants such as Tweens or Spans and/or other similar emulsifying agents or bioavailability enhancers which are commonly used in the manufacture of pharmaceutically acceptable solid, liquid, or other dosage forms may also be used for the purposes of formulation.
The compositions of this invention may be orally administered in any orally acceptable dosage form including, but not limited to, capsules, tablets, emulsions and aqueous suspensions, dispersions and solutions. In the case of tablets for oral use, carriers which are commonly used include lactose and corn starch. Lubricating agents, such as magnesium stearate, are also typically added. For oral administration in a capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions and/or emulsions are administered orally, the active ingredient may be suspended or dissolved in an oily phase is combined with emulsifying and/or suspending agents. If desired, certain sweetening and/or flavoring and/or coloring agents may be added.
The compositions of this invention may also be administered in the form of suppositories for rectal administration. These compositions can be prepared by mixing a compound of this invention with a suitable non-irritating excipient which is solid at room temperature but liquid at the rectal temperature and therefore will melt in the rectum to release the active components. Such materials include, but are not limited to, cocoa butter, beeswax and polyethylene glycols.
Topical administration of the compositions of this invention is useful when the desired treatment involves areas or organs readily accessible by topical application. For application topically to the skin, the composition should be formulated with a suitable ointment containing the active components suspended or dissolved in a carrier. Carriers for topical administration of the compounds of this invention include, but are not limited to, mineral oil, liquid petroleum, white petroleum, propylene glycol, polyoxyethylene polyoxypropylene compound, emulsifying wax and water. Alternatively, the composition can be formulated with a suitable lotion or cream containing the active compound suspended or dissolved in a carrier with suitable emulsifying agents. Suitable carriers include, but are not limited to, mineral oil, sorbitan monostearate, polysorbate 60, cetyl esters wax, cetearyl alcohol, 2-octyldodecanol, benzyl alcohol and water. The compositions of this invention may also be topically applied to the lower intestinal tract by rectal suppository formulation or in a suitable enema formulation.
Topically-transdermal patches are also included in this invention. Also within the invention is a patch to deliver active chemotherapeutic combinations herein. A patch includes a material layer (e.g., polymeric, cloth, gauze, bandage) and the compound of the formulae herein as delineated herein. One side of the material layer can have a protective layer adhered to it to resist passage of the compounds or compositions. The patch can additionally include an adhesive to hold the patch in place on a subject. An adhesive is a composition, including those of either natural or synthetic origin, that when contacted with the skin of a subject, temporarily adheres to the skin. It can be water resistant. The adhesive can be placed on the patch to hold it in contact with the skin of the subject for an extended period of time. The adhesive can be made of a tackiness, or adhesive strength, such that it holds the device in place subject to incidental contact, however, upon an affirmative act (e.g., ripping, peeling, or other intentional removal) the adhesive gives way to the external pressure placed on the device or the adhesive itself, and allows for breaking of the adhesion contact. The adhesive can be pressure sensitive, that is, it can allow for positioning of the adhesive (and the device to be adhered to the skin) against the skin by the application of pressure (e.g., pushing, rubbing,) on the adhesive or device.
The compositions of this invention may be administered by nasal aerosol or inhalation. Such compositions are prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art.
A composition having the compound of the formulae herein and an additional agent (e.g., a therapeutic agent) can be administered using any of the routes of administration described herein. In some embodiments, a composition having the compound of the formulae herein and an additional agent (e.g., a therapeutic agent) can be administered using an implantable device. Implantable devices and related technology are known in the art and are useful as delivery systems where a continuous, or timed-release delivery of compounds or compositions delineated herein is desired. Additionally, the implantable device delivery system is useful for targeting specific points of compound or composition delivery (e.g., localized sites, organs). Negrin et al., Biomaterials, 22(6):563 (2001). Timed-release technology involving alternate delivery methods can also be used in this invention. For example, timed-release formulations based on polymer technologies, sustained-release techniques and encapsulation techniques (e.g., polymeric, liposomal) can also be used for delivery of the compounds and compositions delineated herein.
The invention will be further described in the following examples. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner.
EXAMPLES
Representative compounds of this invention were evaluated in standard pharmacological test procedures which measured their affinity to bind to LXR and to upregulate the gene ABCA1, which causes cholesterol efflux from atherogenic cells, such as macrophages.
LXR activation can be critical for maintaining cholesterol homeostasis, but its coincident regulation of fatty acid metabolism may lead to increased serum and hepatic triglyceride levels. Selective LXR modulators that activate cholesterol efflux with minimal impact on SREBP-1c expression and triglyceride synthesis in liver would be expected to reduce atherosclerotic risk with an improved therapeutic index and minimize the potential for deleterious effects on metabolic balance. A method is described herein for identifying selective LXR ligands with differential activity for regulating ABCA1 (ABCG1) vs. SREBP-1c.
Accordingly, LXR ligands were identified initially in cell-free LXR beta and LXR alpha competition binding assays. LXR ligands were further characterized by gene expression profiling for tissue selective gene regulation. Selective LXR modulators demonstrate agonist activity for ABCA1 transactivation but exhibit no effect or inhibition of SREBP-1c gene expression in differentiated THP-1 macrophages. Gene expression analysis in an antagonist mode was used to further delineate differential regulation of ABCA1 and SREBP-1c gene expression. In a competition assay with known potent synthetic LXR agonists, selective LXR ligands preferentially antagonize SREBP-1c activation (a marker for genes involved in cholesterol and fatty acid homeostasis) but have minimal or additive effects on ABCA1 gene expression or genes known to enhance HDL biogenesis. Cell type or tissue specificity may be further evaluated in additional cell lines, intestinal, CaCo2 or liver, HepG2 and Huh-7 cells where ABCA1 activity influences net cholesterol absorption and reverse cholesterol transport.
The test procedures performed, and results obtained are briefly described below.

Materials and Methods
Cell culture: The THP-1 monocytic cell line (ATCC # TIB-202) was obtained from American Type Culture Collection (Manassas, Va.) and cultured in RPMI 1640 medium (Gibco, Carlsbad, Calif.) containing 10% FBS, 2 mM L-glutamine, and 55 uM beta-Mercaptoethanol (BME). Cells were plated in 96-well format at a density of 7.5×104 in complete medium containing 50-100 ng/ml phorbal 12,13-dibutyrate (Sigma, St. Louis, Mo.) for three days to induce differentiation into adherent macrophages. Differentiated THP-1 cells were treated with test compounds or ligands dissolved in DMSO (Sigma, D-8779) in culture medium lacking phorbal ester. Final concentrations of DMSO did not exceed 0.3% of the media volume. Dose response effects were measured in duplicate, in the range of 0.001 to 30 micromolar concentrations and treated cells were incubated for an additional 18 hrs prior to RNA isolation. Unstimulated cells treated with vehicle were included as negative controls on each plate. An LXR agonist reference, N-(2,2,2-trifluoro-ethyl)-N-[4-(2,2,2-trifluoro-1-hydroxy-1-trifluoromethyl-ethyl)-phenyl]-benzenesulfonamide (Schultz, Joshua R., Genes & Development (2000), 14(22), 2831-2838), was dosed at 1.0 uM and served as a positive control. In antagonist mode, the compound under study is analyzed in the presence of 150 nM GW3965, trifluoromethyl-benzyl)-(2,2-diphenyl-ethyl)-amino]-propoxy]-phenyl)-acetic acid (Collins, J. L., J. Med.
