This invention provides quinolines that are useful in the treatment or inhibition of LXR mediated diseases.
Atherosclerosis, a complex disease of lipid disorder and inflammation, is the leading cause of death in developed countries. A number of independent risk factors have been identified and the most notable are high levels of serum LDL cholesterol and low HDL cholesterol. Although some of the most effective therapies such as statins have been shown to lower LDL cholesterol significantly (20-60%), still most patients experience adverse coronary events. Also, statins have their own undesirable side effect profile (myotoxicity) which prevent many patients from taking them. Therefore, additional therapeutic strategies to not only decrease LDL cholesterol but also increase HDL cholesterol are critically needed. An important reason to increase HDL cholesterol is to increase cholesterol transport from peripheral tissues to liver for metabolism and excretion. This function of transporting cholesterol from periphery to liver is called reverse cholesterol transport and HDL plays a major role in this pathway. In addition, HDL has been suggested 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. The key transporter involved in HDL production and reverse cholesterol transport is ABCA1. Therefore, upregulation of ABCA1 results in increased reverse cholesterol transport as well as inhibition of cholesterol absorption in the gut.
LXRs (Liver X receptors), originally identified from liver as orphan receptors, are members of the nuclear hormone receptor super family and are involved in the regulation of cholesterol and lipid metabolism. They are ligand-activated transcription factors and bind to DNA as obligate heterodimers with retinoid X receptors. While LXRα is restricted to certain 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 ABCA1, ABCG1 and ApoE. Studies have been conducted in LXRα k/o, LXRβ k/o and double k/o mice to determine the physiological role of LXRs in lipid homeostasis and atherosclerosis. The data indicate that in double k/o mice on normal chow diet, increased cholesterol accumulation was observed in macrophages (foam cells) of spleen, lung and arterial wall. This was associated with reduced serum HDL cholesterol and increased LDL cholesterol despite normal total cholesterol levels. While LXRα k/o mice did not 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. Agonists of LXRα or β are very effective in upregulating ABCA1 expression (desirable effect) in macrophages. The biological activities of several agonists have been shown in two atherosclerotic mouse models (ApoE k/o and LDLR k/o). Treatment of these mice with agonists for 12 weeks resulted in significant inhibition of atherosclerotic lesions. While these two compounds had variable effects on serum cholesterol and lipoprotein levels, both compounds caused a significant increase in serum HDL cholesterol and triglyceride levels. These in vivo data agree well with the in vitro data obtained for the compounds in macrophages.
In addition to the lipid and triglyceride effects described above, a very recent communication in Nature Medicine (9: 213-219, 2003) presents convincing data that activation of LXRs results in the inhibition of inflammation and proinflammatory gene expression in 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 two-pronged effect (removal of cholesterol from the macrophages and inhibition of vascular inflammation) resulting in the inhibition of atherosclerotic lesion.

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 is 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.

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. Chem. (2000), 45:1963-1966.). Results of antagonist analysis are expressed as % antagonism and IC50 (in μM).
RNA isolation and quantitation: Total cellular RNA was isolated from treated cells cultured in 96-well plates using PrepStation 6100 (Applied Biosystems, Foster City, Calif.), according to the manufacturer's recommendations. RNA was resuspended in ribonuclease-free water and stored at −70° C. prior to analysis. RNA concentrations were quantitated with RiboGreen test procedure, #R-11490 (Molecular Probes, Eugene, Oreg.).
Gene expression analysis: Gene-specific mRNA quantitation was performed by real-time PCR with the Perkin Elmer Corp. chemistry on an ABI Prism 7700 Sequence detection system (Applied Biosystems, Foster City, Calif.) according to the manufacturer's instructions. Samples (50-100 ng) of total RNA were assayed in duplicate or triplicate in 50 μl reactions using one-step RT-PCR and the standard curve method to estimate specific mRNA concentrations. Sequences of gene-specific primer and probe sets were designed with Primer Express Software (Applied Biosystems, Foster City, Calif.). The human ABCA1 primer and probe sequences are: forward, CMCATGMTGCCATTTTCCAA, reverse, ATAATCCCCTGAACCCAAGGA, and probe, 6FAM-TAAAGCCATGCCCTCTGCAGGAACA-TAMRA. RT and PCR reactions were performed according to PE Applied Biosystem's protocol for Taqman Gold RT-PCR or Qiagen's protocol for Quantitect probe RT-PCR. Relative levels of ABCA1 mRNA are normalized using GAPDH mRNA or 18S rRNA probe/primer sets purchased commercially (Applied Biosystems, Foster City, Calif.).

It is understood that the effective dosage of the active compounds of this invention may vary depending upon the particular compound utilized, the mode of administration, the condition, and severity thereof, of the condition being treated, as well as the various physical factors related to the individual being treated. It is projected that compounds of this invention will be administered at an oral daily dosage of from about 0.05 mg to about 30 mg per kilogram of body weight, preferably administered in divided doses two to six times per day, or in a sustained release form, and may be adjusted to provide the optimal therapeutic result.
The compounds of this invention can be formulated neat or with a pharmaceutical carrier for administration, the proportion of which is determined by the solubility and chemical nature of the compound, chosen route of administration and standard pharmacological practice. The pharmaceutical carrier may be solid or liquid.
A solid carrier can include one or more substances which may also act as flavoring agents, sweetening agents, lubricants, solubilizers, suspending agents, fillers, glidants, compression aids, binders, or tablet-disintegrating agents; it can also be an encapsulating material. In powders, the carrier is a finely divided solid which is in admixture with the finely divided active ingredient.
Solid dosage unit forms or compositions such as tablets, troches, pills, capsules, powders, and the like, may contain a solid carrier 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.
Liquid carriers are used in preparing liquid dosage forms such as solutions, suspensions, dispersions, emulsions, syrups, elixirs and pressurized compositions. The active ingredient can be dissolved or suspended in a pharmaceutically acceptable liquid carrier such as water, an organic solvent, a mixture of both, or pharmaceutically acceptable oils or fats. The liquid carrier can contain other suitable pharmaceutical additives such as solubilizers, emulsifiers, buffers, preservatives, sweeteners, flavoring agents, suspending agents, thickening agents, colors, viscosity regulators, stabilizers or osmo-regulators. Suitable examples of liquid carriers for oral and parenteral administration include water (partially containing additives as above, e.g. cellulose derivatives, preferably sodium carboxymethyl cellulose solution); alcohols, including monohydric alcohols such as ethanol and polyhydric alcohols such as glycols and their derivatives; lethicins, and oils such as fractionated coconut oil and arachis oil. For parenteral administration, the liquid carrier can also be an oily ester such as ethyl oleate and isopropyl myristate. Sterile liquid carriers are useful in sterile liquid form compositions for parenteral administration. The liquid carrier for pressurized compositions can be a halogenated hydrocarbon or other pharmaceutically acceptable propellant.
A liquid pharmaceutical composition such as a syrup or elixir may contain, in addition to one or more liquid carriers and the active ingredients, a sweetening agent such as sucrose, preservatives such as methyl and propyl parabens, a pharmaceutically acceptable dye or coloring agent, or a flavoring agent such as cherry or orange flavoring.
Liquid pharmaceutical compositions which are sterile solutions or suspensions can be administered intraocularly or parenterally, for example, by intramuscular, intraperitoneal or subcutaneous injection. Sterile solutions can also be administered intravenously. 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 injectability 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 a liquid carrier, for example, water, ethanol, polyol (e.g. glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oils. The liquid carrier may be suitably mixed with a surfactant such as hydroxypropylcellulose.
The compounds of the present invention may also be administered rectally or vaginally in the form of a conventional suppository. For administration by intranasal or intrabronchial inhalation or insufflation, the compounds of this invention may be formulated into an aqueous or partially aqueous solution, which can then be utilized in the form of an aerosol. The compounds of this invention may be administered topically, or also transdermally through the use of a transdermal patch containing the active compound and a carrier that is inert to the active compound, which is non toxic to the skin, and allows delivery of the agent for systemic absorption into the blood stream via the skin. The carrier may take any number of forms such as creams and ointments, pastes, gels, and occlusive devices. The creams and ointments may be viscous liquid or semisolid emulsions of either the oil-in-water or water-in-oil type. Pastes comprised of absorptive powders dispersed in petroleum or hydrophilic petroleum containing the active ingredient may also be suitable. A variety of occlusive devices may be used to release the active ingredient into the blood stream such as a semipermeable membrane covering a reservoir containing the active ingredient with or without a carrier, or a matrix containing the active ingredient. Other occlusive devices are known in the literature.
