This invention relates to methods of treating disorders associated with neovascularization, vascular leakage, inflammation and angiogenesis, and more particularly to using epoxymetabolites of a long chain polyunsaturated fatty acids and inhibitors of a soluble epoxide hydrolase to treat these disorders.
Age-related macular degeneration (AMD) is the most common cause of blindness for the elderly in the developed world. Choroidal neovascularization (CNV) is a hallmark of the neovascular (wet) form of advanced AMD and leads to significant vision loss.
There is a need for new nutritional or pharmacological interventions that are safe over the long term for the treatment or prevention of diseases associated with neovascularization (e.g., AMD).
Provided herein are methods of reducing neovascularization, reducing choroidal neovascularization (CNV) lesions, reducing vascular leakage, reducing inflammation and reducing angiogenesis, e.g., reducing or reversing angiogenesis, in a subject by administering to a subject in need thereof one or more epoxymetabolites derived from omega-3 long chain polyunsaturated fatty acids (ω-3 LCPUFAs), e.g., cytochrome P450 (CYP) derived epoxymetabolites of docosahexaenoic acid (DHA), including epoxydocosapentaenoic acid (EDP) analogs (e.g., 7,8-EDP; 10,11-EDP; 13,14-EDP; 16,17-EDP, 19,20-EDP); and/or CYP-derived epoxymetabolites of eicosapentaenoic acid (EPA) including epoxyeicosaquatraenoic acid (EEQ) analogs (e.g., 8,9-EEQ; 11,12-EEQ; 14,15-EEQ; 17,18-EEQ), e.g., one or both of 17,18-epoxyeicosatetraenoic acid (EEQ) and 19,20-epoxydocosapentaenoic acid (EDP); and one or more inhibitors of soluble epoxide hydrolase (sEH), e.g., derivatives of urea (e.g., 1-(1-propionylpiperidin-4-yl)-3-(4-(trifluoromethoxy)phenyl)urea).

Age-related macular degeneration (AMD) is a progressive chronic disease and a leading cause of irreversible visual impairment in developed countries (1). AMD is generally classified into two forms: exudative (“wet”) and nonexudative (“dry”). Advanced exudative AMD is characterized by neovascularization arising from the choroid and infiltrating the subretinal space. This choroidal neovascularization (CNV) is immature and leaky in nature, resulting in subretinal and intraretinal edema and hemorrhage that can lead to severe vision loss (2, 3). Current standard therapy for patients with CNV involves inhibiting vascular endothelial growth factor (VEGF), a molecule that promotes angiogenesis and vascular permeability (3-5). Despite their therapeutic value, intravitreal injections of anti-VEGF agents do not result in vascular regression; thus, frequent anti-VEGF injections are necessary to keep these abnormal vessels at bay (4, 5). Anti-VEGF therapy in patients has also been shown to lead to progressive vision loss with long-term use (6). Moreover, substantial vision improvement occurs in only one-third of patients treated with VEGF antagonists, and one-sixth of treated patients still progress to legal blindness (4, 5). Accordingly, there is a need for pharmacological interventions for the treatment of AMD.
Omega (ω)-3 and ω-6 fatty acids are two functionally distinct subsets of long chain polyunsaturated fatty acids (LCPUFAs) (7, 8). The metabolism of arachidonic acid (AA), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) into biologically active lipid mediators by cyclooxygenase (COX) and lipoxygenase (LOX) enzymes is relatively well established (10, 11). However, these LCPUFAs are also substrates for the cytochrome P450 (CYP) enzymes, which contain two main branches: ω-hydroxylases, which convert AA to hydroxyeicosatetraenoic acids (HETEs); and epoxygenases, which convert AA to epoxyeicosatrienoic acids (EETs) (12, 13). Of the three main pathways involved in eicosanoid biosynthesis (i.e., COX, LOX, and CYP), the lipid biometabolites of the CYP-branch are susceptible to changes in dietary fatty acid composition (13). The ω-3 double bond that distinguishes DHA and EPA from their ω-6 counterparts provides a preferred epoxidation site for specific CYP family members. The principal CYP metabolites derived from DHA are epoxydocosapentaenoic acids (EDPs), while those derived from EPA are epoxyeicosaquatraenoic acids (EEQs) (12). EETs, EDPs, and EEQs are potent modulators of both inflammation and vascular function (12, 13). These fatty acid metabolites are produced primarily in the endothelium by CYP2C and CYP2J monooxygenase families and are further metabolized by soluble epoxide hydrolase (sEH) into less active dihydroxyeicosatrienoic acids (DHETs), dihydroxydocosapentaenoic acids (DHDPs), and dihydroxyeicosaquatraenoic acids (DHEQs) (derived from AA, DHA, and EPA, respectively), thereby conferring regulation of these bioactive lipid metabolites (12-14).

Less commonly, the abnormal vessels originate from retinal vasculature. These blood vessels are immature and leaky, resulting in subretinal and intraretinal edema and hemorrhage, which leads to vision loss. Neovascular AMD accounts for 10-15% of AMD cases, and if left untreated, can rapidly lead to substantial vision loss.
In some embodiments, the age-related macular degeneration (AMD) is atrophic. In some embodiments, the age-related macular degeneration (AMD) is neovascular.

Long Chain Polyunsaturated Fatty Acid (LCPUFA) and their Metabolites
The ω-3 and ω-6 LCPUFAs are two classes of dietary lipids that are highly enriched in the retina and are thought to have opposing physiological effects. The ω-3 LCPUFAs have anti-thrombotic and anti-inflammatory properties, and compete with ω-6 LCPUFAs for downstream eicosanoids synthesis at the CYP, cyclooxygenase, and lipoxygenase levels. Mammals depend on dietary intake of LCPUFAs because they lack the enzymes that synthesize these molecules de novo. The ω-6 LCPUFAs are the primary polyunsaturated fatty acids found in western diets. Dietary enrichment with ω-3 LCPUFAs has been shown to be protective against pathological angiogenesis, which occurs in cancer and retinopathies. Prospective clinical studies have suggested that dietary ω-3 LCPUFAs may protect against AMD. In a prospective cohort study of 1837 participants at moderate-to-high risk of developing advanced AMD, those who reported the highest intake of ω-3 LCPUFAs (median of 0.11% of total energy intake) were 30% less likely than their peers to develop the condition over a 12-year period.

Inhibitors of a Soluble Epoxide Hydrolase
Soluble epoxide hydrolase (sEH) is a member of the epoxide hydrolase family of enzymes. This enzyme binds to specific epoxides and converts these molecules to the corresponding diols. sEH is expressed in numerous tissues including liver, vascular endothelium, leukocytes, red blood cells, smooth muscle cells, adipocytes and the kidney proximal tubule. Epoxymetabolites of long chain polyunsaturated fatty acids (such as those derived from AA, DHA, and EPA) are hydrolyzed by soluble epoxide hydrolase (sEH) into less active dihydroxyeicosatrienoic acids (DHETs), dihydroxydocosapentaenoic acids (DHDPs), and dihydroxyeicosaquatraenoic acids (DHEQs), respectively, thereby conferring regulation of these bioactive lipid metabolites.
The methods presented herein advantageously achieve increased half-life and bioavailability of the epoxymetabolites of long chain polyunsaturated fatty acids by inhibiting sEH using inhibitors of the sEH enzyme.
In some embodiments, the inhibitor of a soluble epoxide hydrolase is a derivative of urea. In some embodiments, the inhibitor of a soluble epoxide hydrolase is found in plants.

Combination Treatments-Anti-VEGF Agents
In some embodiments, the methods include co-administering an anti-Vascular Endothelial Growth Factor (VEGF) agent. In some embodiments, the anti-VEGF agent blocks VEGF signaling. There are at least three methods to block VEGF signaling that have been used to date. The first method is to inhibit VEGF (e.g. VEGF-A, -B, -C, -D, PGF) and/or VEGFR (e.g. VEGFR-1, -2, -3) using antibodies. Examples include: Avastin (bevacizumab), a recombinant humanized monoclonal antibody that binds to VEGF-A and prevent interaction of VEGF-A to VEGFR-1 and VEGFR-2 (see, e.g., Presta et al., Cancer Res. 57: 4593-4599 (1997); Hurwitz et al., N. Engl. J. Med. 350:2335-2342) (2004); 2C3, a mouse monoclonal antibody against VEGF-A (Zhang et al., Angiogenesis. 5:35-44 (2002); Brekken et al., Cancer Res. 58: 1952-9 (1998)); IMC-1121B, a human monoclonal antibody against VEGFR-2 (Rockwell and Goldstein, U.S. Pat. No. 6,811,779); CDP-791, PEGylated, humanized di-Fab fragment that binds to VEGFR-2 (Ton et al., Clin. Cancer Res. 13:7113-711 (2007)). Lucentis (ranibizumab) is a recombinant humanized monoclonal antibody that binds to VEGF-A, but its approved usage is for treatment of patients with neovascular age-related macular degeneration (available from Genentech).
A second method uses protein kinase inhibitors to inhibit VEGFR (e.g. VEGFR-1, -2, -3). At least two known FDA-approved small molecule inhibitors are on the market: Sutent (sunitinib) (Goodman et al., Clin. Cancer Res. 13:1367-1373 (2007)) and Nexavar (sorafenib) (Kane et al., Clin. Cancer Res. 12:7271-8 (2006)). Other kinase inhibitors include, but are not limited to: Vatalanib (PTK787/ZK222584) which inhibits VEGFR-1, -2, and -3 (Wood et al., Cancer Res. 60:2178-2189 (2000)); CEP-7055, inhibitor of VEGFR-1, -2, and -3 (Ruggeri et al., Cancer Res. 63: 5978-5991 (2003)); CP-547,632, inhibitor of VEGFR-2 and FGF (Beebe et al., Cancer Res. 63: 7301-7309 (2003)).
A third method uses the so-called “VEGF-trap,” i.e., soluble hybrid VEGF receptors that bind to the VEGF ligand and prevent binding to VEGFRs (Holash et al., Proc. Natl. Acad. Sci. 99:11393-11398 (2002)).
In some embodiments, the anti-VEGF agent is an anti-VEGF antibody or antigen-binding portions thereof (such as Fv, Fab, or scFv portions) to inhibit VEGF binding to KDR and/or flt receptors, e.g., Avastin® (Bevacizumab). Avastin is a recombinant humanized monoclonal IgG1 antibody that binds to and inhibits the biologic activity of human VEGF both in vitro and in vivo. Bevacizumab contains human framework regions and the complementarity-determining regions of a murine antibody that binds to VEGF (Presta et al., Cancer Res 57:4593-9 1997). Avastin is available from Genentech (South San Francisco, Calif.). See also: Schlaeppi and Wood, Cancer and Metastasis Rev. 1999; 18:473-481; U.S. Pat. Nos. 7,169,901; 7,056,509; and 7,297,334; U.S. Pat. Pub. No. 20020032315; 20080187966; and 20090010883; and PCT No. WO 94/10202. In some embodiments, the antibody binds specifically to VEGF and block binding to VEGFR1, to VEGFR2, or block binding to both VEGFR1 and VEGFR2.
Other anti-VEGF agents include VEGF antagonists, which could compete with VEGF for binding to KDR and/or flt receptors (e.g. soluble truncated forms of flt receptor, which bind to VEGF, as described, for example, in WO 94/21679); and tyrosine kinase inhibitors.
In some embodiments, the anti-VEGF agent is a small interfering RNA (siRNA) targeting VEGF or a VEGFR, e.g., Bevasiranib (CandS; OPKO Health; a modified siRNA targeting all VEGF-A splice forms) or AGN-745 (Sirna-027; Merck; a chemically modified siRNA targeting VEGFR-1), see, e.g., de Fougerolles, Human Gene Therapy 19:125-132 (2008); and anti-VEGF aptamers (e.g., Macugen (pegaptanib; OSI Pharmaceuticals, a pegylated anti-VEGF-A aptamer), see, e.g., Tremolada et al. Am. J. Cardiovasc. Drugs 7:393-398 (2007)).
In some embodiments, the anti-VEGF agent is administered as part of the same treatment regimen as the compounds described herein. In some embodiments, the anti-VEGF agent is co-administered, e.g., as part of the same pharmaceutical composition as described above.

Other formulations may conveniently be presented in unit dosage form, e.g., tablets, sustained release capsules, and in liposomes, and may be prepared by any methods well known in the art of pharmacy. See, for example, Remington: The Science and Practice of Pharmacy, Lippincott Williams & Wilkins, Baltimore, Md. (20th ed. 2000).
In some embodiments, for treatment of ophthalmic conditions, intraocular administration or administration by eye drops may be used, inter alia; see, e.g., U.S. Pat. No. 7,582,785. Solutions or suspensions used for parenteral, intradermal, intraocular or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution (e.g., 0.9% saline solution), dextrose solution (e.g., 5%) dextrose solution), fixed oils, polyethylene glycols (e.g., PEG400), glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.
Such preparative methods include the step of bringing into association with the molecule to be administered ingredients such as the carrier that constitutes one or more accessory ingredients. In general, the compositions are prepared by uniformly and intimately bringing into association the active ingredients with liquid carriers, liposomes or finely divided solid carriers, or both, and then, if necessary, shaping the product.
In some embodiments, an epoxymetabolite of a long chain polyunsaturated fatty acid (LCPUFA) or an inhibitor of a soluble epoxide hydrolase is administered orally. Compositions of the present application suitable for oral administration may be presented as discrete units such as capsules, sachets, or tablets each containing a predetermined amount of the active ingredient; a powder or granules; a solution or a suspension in an aqueous liquid or a non-aqueous liquid; an oil-in-water liquid emulsion; a water-in-oil liquid emulsion; packed in liposomes; or as a bolus, etc. Soft gelatin capsules can be useful for containing such suspensions, which may beneficially increase the rate of compound absorption. In some embodiments, the inhibitor of a soluble epoxide hydrolase is administered to the subject with drinking water. In some embodiments, the inhibitor of a soluble epoxide hydrolase is administered to the subject as a solution in water, aqueous buffer (e.g., sodium phosphate buffer), ethanol, PEG400, triglycerides, trioleate, or mixtures thereof. In some embodiments, the solution of inhibitor of a soluble epoxide hydrolase in any of the aforementioned solvents is added to drinking water. In these cases, the amount of solvent in the drinking water is about 0.1% or less.
In the case of tablets for oral use, carriers that 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 cornstarch.

If desired, certain sweetening and/or flavoring and/or coloring agents may be added.
Compositions suitable for oral administration include lozenges comprising the ingredients in a flavored basis, usually sucrose and acacia or tragacanth; and pastilles comprising the active ingredient in an inert basis such as gelatin and glycerin, or sucrose and acacia.
Compositions suitable for parenteral administration include aqueous and non-aqueous sterile injection solutions which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending agents and thickening agents. The formulations may be presented in unit-dose or multi-dose containers, for example, sealed ampules and vials, and may be stored in a freeze dried (lyophilized) condition requiring only the addition of the sterile liquid carrier, for example water for injections, immediately prior to use. Extemporaneous injection solutions and suspensions may be prepared from sterile powders, granules and tablets. In some embodiments, the epoxymetabolite of a long chain polyunsaturated fatty acid (LCPUFA) is administered by local injection into or near the cornea, choroid, retina, vitreous, uvea, orbit, eyelid, conjunctiva, or iris.
Such injection solutions may be in the form, for example, of 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.
The pharmaceutical compositions of the present application may be administered in the form of suppositories for rectal administration. These compositions can be prepared by mixing a compound of the present application 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.

Materials and methods.
Animals:
All animal procedures adhered to the Association for Research in Vision and Ophthalmology Statement for the Use of Animals in Ophthalmic and Vision Research. The Animal Care and Use Committee of Massachusetts Eye and Ear Infirmary approved the protocol for the experiments outlined herein. Tie2-CYP2C8 transgenic (Tg) mice, which overexpress human CYP2C8 in endothelial cells (Lee C R, et al. (2010) Endothelial expression of human cytochrome P450 epoxygenases lowers blood pressure and attenuates hypertension-induced renal injury in mice. FASEB J 24(10):3770-3781); Tie2-hsEH Tg mice, which overexpress human sEH in endothelial cells (Edin M L, et al. (2011) Endothelial expression of human cytochrome P450 epoxygenase CYP2C8 increases susceptibility to ischemia-reperfusion injury in isolated mouse heart. FASEB J 25(10):3436-3447); and sEH null mice, which have systemic knockout of sEH (Sinal C J, et al. (2000) Targeted disruption of soluble epoxide hydrolase reveals a role in blood pressure regulation. J Biol Chem 275(51):40504-40510), were kindly provided by Dr. Darryl C. Zeldin (NIH/NIEHS). All mice were on the C57BL/6 (area R16) genetic background from Charles River (Wilmington, Mass., USA). These C57BL/6 mice were used as control mice for CNV experiments involving the aforementioned CYP Tg mice. Male C57BL/6 mice (stock no. 000664) at 6 to 8 weeks of age obtained from Jackson Laboratories (Bar Harbor, Me., USA) were used for all other experiments.
Diet and Bioactive Lipid Metabolites:
Mice were fed one of three experimental diets: a diet containing high ω-3 LCPUFAs [eicosapentaenoic acid (EPA) 478.5 mg/g diet and docosahexaenoic acid (DHA) 193.5 mg/g diet, with no arachidonic acid (AA)], a diet devoid of ω-3 LCPUFAs but containing the ω-6 LCPUFA AA [2% (wt/wt)], and a standard control diet which was completely devoid of AA, EPA, and DHA; the base fatty acids in the diets originated predominantly from soybean. The ω-3 LCPUFAs were obtained from Pronova Biopharma (PronovaPure 500:200 EE, Denmark) and the experimental diets were formulated by ssniff (Germany). Mice were placed on these diets 2 weeks prior to the induction of CNV and for the rest of the experiment duration. The control diet was used for the experiments involving CYP-derived fatty acids to avoid the influence of fatty acids from the diet. CYP-derived fatty acids, 17,18-epoxyeicosaquatraenoic acid (EEQ), 19,20-epoxydocosapentaenoic acid (EDP), and 8,9-, 11,12-, 14,15-epoxyeicosatrienoic acid (EET), were obtained from Cayman Chemical (Ann Arbor, Mich., USA). Mice were injected intraperitoneally (i.p.) daily with 17,18-EEQ, 19,20-EDP, 8,9-, 11,12-, 14,15-EETs, or PBS as a vehicle control beginning immediately after CNV induction. Based on our earlier work, a dose of 50 μg/kg/day for these agents was used to assess the role of each of the aforementioned bioactive metabolites in the laser-induced CNV model (Yanai R, et al. (2014) Cytochrome P450-generated metabolites derived from omega-3 fatty acids attenuate neovascularization. Proc Natl Acad Sci USA 111(26):9603-9608). The stable 17,18-EEQ analog, named C21, was synthesized as previously described (Falck J R, et al. (2011) 17(R),18(S)-epoxyeicosatetraenoic acid, a potent eicosapentaenoic acid (EPA) derived regulator of cardiomyocyte contraction: structure-activity relationships and stable analogues. J Med Chem 54(12):4109-4118). This analog was also injected 50 μg/kg/day i.p. daily at the same dose as the other fatty acid metabolites. 1-Trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea, a potent sEH inhibitor, was synthesized as previously described (Rose T E, et al. (2010) 1-Aryl-3-(1-acylpiperidin-4-yl)urea inhibitors of human and murine soluble epoxide hydrolase: structure-activity relationships, pharmacokinetics, and reduction of inflammatory pain. J Med Chem 53(19):7067-7075), dissolved in polyethylene glycol 400 (PEG400), and administered in the drinking water at a dose of 1 mg/kg/day 3 days prior to the induction of CNV and through the duration of the experiment. Drinking water containing PEG400 alone served as the vehicle control group.
Laser-Induced CNV Model:
A 532 nm laser (Oculight GLx Laser System, IRIDEX) attached to a slit lamp was used for photocoagulation. In order to view the posterior pole of the eye, a coverslip with a drop of Goniosol was applied to applanate the cornea. For size and leakage studies, 4 laser-induced lesions were made around the optic nerve in a clock-wise manner (i.e., 3, 6, 9, and 12 o'clock). For fluorescence-activated cell sorting (FACS) and laser-capture microdissection (LCM) analysis, 10 lesions were placed. The laser was set as follows: 100 mW power, 100 μm spot size, and 0.1 s pulse duration. The appearance of a bubble at the site of photocoagulation signified a disruption in Bruch's membrane, and so any laser-injury without a corresponding bubble was excluded from analysis. Seven days after laser treatment, mouse eyes were enucleated and subsequently fixed in 4% paraformaldehyde. Whole retinas were then separated from the underlying choroid and sclera (i.e., eyecup). At a dilution of 1:100, Alexa Fluor 488 conjugated to isolectin B4 (Invitrogen) was used to stain the eyecup overnight at room temperature. PermaFluor aqueous mount (Thermo Scientific) was then used to flatmount the eyecup with the choroid facing upward and the sclera facing downward. Flatmount images were captured using a Zeiss AxioCam MRm camera and Zeiss AxioObserver (Z1) microscope, and ImageJ software (National Institutes of Health) was used to assess fluorescent CNV lesions.
Fluorescein Angiography:
A Micron IV Retinal Imaging Microscope (Phoenix Research Laboratories, Pleasanton, Calif.) was used to take fluorescein images. First, mice were anesthetized with Avertin (Sigma, St. Louis, Mo.) and kept on a heating pad (37° C.) to maintain body temperature. 5% phenylephrine and 0.5% tropicamide were used for pupil dilation. The corneas were covered with 2.5% Goniovisc (HUB Pharmaceuticals, Rancho Cucamonga, Calif.) and then placed in contact with the Micron camera lens. Images were obtained 3-5 and 7-10 minutes after i.p. injection of 0.1 ml of 2% fluorescein sodium (Akorn, Lake Forest, Ill.) using StreamPix software (Phoenix Research Laboratories, Pleasanton, Calif.). A previously established scheme was used to grade the hyperfluorescent lesions: faint or mottled fluorescence without leakage was scored as 0 (i.e., no leakage); hyperfluorescence without any increase in size or intensity was scored as 1 (i.e., debatable leakage); hyperfluorescence with constant size but increasing intensity was scored as 2A (i.e., definite leakage); and hyperfluorescence with increasing size and intensity was scored as 2B (i.e., clinically significant leakage).
Spectral Domain-Optical Coherence Tomography:
Seven days after laser photocoagulation, a Bioptigen system was used to conduct spectral domain-optical coherence tomography (SD-OCT) as previously described (Yanai R, et al. (2014) Cytochrome P450-generated metabolites derived from omega-3 fatty acids attenuate neovascularization. Proc Natl Acad Sci USA 111(26):9603-9608). Mice were first anesthetized and placed on a freely rotating cassette customized for optimal eye alignment. AB-scan with an area size of 1.4×1.4 mm was obtained using 100 horizontal, raster, and consecutive B-scan lines, each composed of 1,000 A-scans. Cross-sectional CNV lesion size from these OCT images was measured in ImageJ using sections through the center (i.e., midline through the ruptured area of Bruch's membrane and the retinal pigment epithelium) of each CNV lesion.
Liquid Chromatography-Tandem Mass Spectrometry:
Seven days after CNV induction, plasma samples were obtained from mice fed ω-3, ω-6, or control diets for analysis of the CYP-mediated metabolite profile via liquid chromatography-tandem mass spectrometry (LC-MS/MS) as previously described (Arnold C, et al. (2010) Arachidonic acid-metabolizing cytochrome P450 enzymes are targets of {omega}-3 fatty acids. J Biol Chem 285(43):32720-32733). Plasma samples were combined with an internal standard solution (i.e., 10 ng each of 14,15-epoxyeicosatrienoic acid-d8, 20-hydroxyeicosatetraenoic acid-d6, and 14,15-dihydroxyeicosatrienoic acid-al; Cayman Chemical) for subsequent alkaline hydrolysis. Agilent Bond Elute Certify II columns were then used for the solid-phase extraction of metabolites. Metabolite analysis was performed in a solvent system (acetonitrile and 0.1% aqueous formic acid) with an Agilent 1200 HPLC system and Phenomenex Kinetex-C18 column (2.6 μm; 2.1 Ř150 mm). Starting at a 5% acetonitrile concentration, gradient elution was conducted by increasing the acetonitrile concentration to 90% in 10 min and then held at 90% for 10 min, with a flow rate of 0.3 mL/min. The HPLC system was linked to a mass spectrometer (Agilent 6460 triple quadrupole) with a source of electrospray ionization. As previously described (Arnold C, et al. (2010) Arachidonic acid-metabolizing cytochrome P450 enzymes are targets of {omega}-3 fatty acids. J Biol Chem 285(43):32720-32733), multiple reaction monitoring (negative mode) was used to analyze the CYP-mediated metabolites, and the results were calculated via Agilent Mass Hunter software. The concentrations of metabolites are expressed in ng/mL of serum or ng/mg of retina protein which were obtained with the Lowry assay.
Autoperfused Microflow Chamber Microscopy:
An autoperfused microflow chamber assay was used to assess leukocyte rolling velocity as previously described (Mulki L, Sweigard J H, & Connor K M (2014) Assessing leukocyte-endothelial interactions under flow conditions in an ex vivo autoperfused microflow chamber assay. J Vis Exp (94)). A combination of intercellular adhesion molecule 1 (ICAM-1) and P-selectin (R&D Systems), each at a concentration of 5 μg/mL, was used to coat translucent microchambers (0.4×0.04×50 mm, VitroCom) overnight at 4° C. Biocompatible polyester tubing (PE10; Becton Dickinson) was attached to both ends of each microchamber, and the apparatus was subsequently incubated for 1 hour with 0.1% BSA (Sigma-Aldrich) in order to prevent nonspecific leukocyte interaction with the inner surface of the apparatus. The left jugular vein and right carotid artery in an anesthetized mouse were surgically connected to the free ends of both tubes, thus allowing blood to flow from the right carotid artery and into the microchamber (via the inlet tube), and then into the left jugular vein (via the outlet tube) for recirculation. Blood flow rate through the microchamber was controlled via a screw valve on the inlet tube that could change the tube diameter. For continuous blood pressure measurements, three-way connectors were used to embed microtransducers (Harvard Apparatus) before and after the microchamber. Digitizing the analog output from these microtransducers required an A/D converter (ML785 PowerLab/8SP; ADInstruments) linked to a computer running CHART V7 software (ADInstruments). In terms of the hemodynamic conditions in the chamber, the pressure drop (ΔP) was calculated as the difference between the recorded pressure readings before (inlet) and after (outlet) the microchamber, and ΔP was used to calculate shear stress (τ) as previously described (Almulki L, et al. (2009) Surprising up-regulation of P-selectin glycoprotein ligand-1 (PSGL-1) in endotoxin-induced uveitis. FASEB J 23(3):929-939; Hafezi-Moghadam A, Thomas K L, & Cornelssen C (2004) A novel mouse-driven ex vivo flow chamber for the study of leukocyte and platelet function. Am J Physiol Cell Physiol 286(4):C876-892). A fixed-stage intravital microscope (Leica) with a 63× objective and a monochromic camera (DFC 360 FX; Leica) were used to observe and record leukocyte rolling along immobilized adhesion molecules. Recordings lasted at least 30 s and incorporated ten different fields of view. Using ImageJ software, leukocyte rolling velocity was calculated based on individual cell displacement along the surface of the chamber over time (i.e., Δd/Δt). Flux was calculated as the mean number of leukocytes interacting with the chamber surface per field of view (i.e., average of 10 independent fields of view). There were no significant differences in the flux of peripheral blood leukocytes (PBLs) from mice on either ω-3 or ω-6 fatty acid diets.
Isolation of PBLs for Flow Cytometric Analysis of CD11b and CD18:
An EDTA-treated syringe was used to obtain blood from mouse hearts. The blood was then incubated on ice for 30 min with phycoerythrin conjugated to rat monoclonal antibodies CD18 (C71/16; BD Biosciences) or CD11b (M1/70; BD Biosciences), or with isotype control antibodies (concentration of 1 μg per 1×106 total cells). After lysing red blood cells (Easy-Lyse, Leinco Technologies), the solution was centrifuged and the remaining cells were resuspended for flow cytometry (Cytomics FC500 instrument, Beckman Coulter). PBLs were gated based on their characteristic forward and side scatter pattern, and subsequent analysis was conducted with FlowJo 10.0 software (Beckman Coulter).
Laser-Capture Microdissection:
Immediately after enucleation, mouse eyes were placed in optimum cutting temperature (OCT) compound and swiftly frozen. Under RNase-free conditions, eyes were cryosectioned (10 μm thickness per section) and mounted on polyethylene naphthalate glass slides (Leica). After dehydrating with washes of 50, 75, and 100% ethanol, the slides were stained with isolectin B4 at a dilution of 1:50 in 1 mM CaCl2. Laser-capture microdissection (Leica LMD 7000 system) was used to isolate chorioretinal vessels in CNV lesions, which were then placed in RNA-stabilizing buffer (RNeasy Micro Kit; Qiagen). Reverse transcription of the extracted RNA was achieved with SuperScript III reverse transcriptase and random hexamer primers (Invitrogen). Real-time PCR was conducted on a StepOne real-time PCR System (Applied Biosystems) with mouse TaqMan expression assays for the following genes (Applied Biosystems): E-selectin (Mm00441278_m1), kam-1 (Mm00516023_m1), and β-actin (Mm00607939_s1). All data were normalized to β-actin cDNA.
Statistical Analysis:
Results are shown as means±SEM. The student t test was used to compare two groups while Dunnett's test was used to compare more than two groups. Statistical significance was defined as a P value of <0.05.
Tie2-CYP2C8-Tg mice overexpress the monooxygenase CYP2C8 in endothelial cells, which promotes the metabolism of the primary LCPUFAs to their active downstream fatty acids.
The size of CNV lesions 7 days after laser induction was significantly decreased in Tie2-CYP2C8-Tg mice fed a diet enriched with EPA and DHA compared to mice fed a control diet, as assessed in choroidal flatmounts and OCT cross-sectional images. Vascular leakage in CNV lesions, assessed by fluorescein angiography, was also significantly decreased in Tie2-CYP2C8-Tg mice fed a diet enriched with EPA and DHA compared to mice on a control diet.
Soluble epoxide hydrolase (sEH), an enzyme that functions downstream of the CYP pathway, metabolizes bioactive fatty acids derived from the primary LCPUFAs into less bioactive diols.
The loss of sEH had a similar effect as the overexpression of the monooxygenase CYP2C8 in endothelial cells. The size of CNV lesions 7 days after laser induction was significantly decreased in sEH null mice fed a diet enriched with EPA and DHA compared to mice on a control diet, as assessed in choroidal flatmounts and OCT cross-sectional images. The severity of vascular leakage in CNV lesions was also significantly decreased in sEH null mice fed a diet enriched with EPA and DHA compared to mice on a control diet.
Tie2-hsEH mice overexpress the sEH enzyme in endothelial cells, which rapidly breakdown CYP-derived fatty acids into less bioactive diols.
When Tie2-hsEH mice were fed a diet enriched with EPA and DHA, the protective effects against CNV seen with this diet were lost. When Tie2-hsEH mice were fed ω-3 diet, the protective effects against CNV obtained from the ω-3 diet were reversed in choroidal flatmount (
Feeding a diet enriched with AA in CYP Tg Mice and administration of EETs in C57BL/6 mice did not alter CNV size or severity compared to their respective base line controls. See
AA-derived EETs do not lead to progression of disease severity but do not affect CNV, while CYP-derived EEQs and EDPs confer protection.
Plasma concentrations of 17,18-EEQ and 19,20-EDP was measured in animals on experimental diets 7 days after laser induction of CNV. LC-MS/MS revealed that EPA-derived 17,18-EEQ was significantly increased in both Tie2-CYP2C8-Tg and sEH null mice fed an EPA and DHA enriched diet compared to their respective strain-matched mice fed a control diet (
17,18-EEQ and 19,20-EDP are the primary effector metabolites in CNV disease resolution (not the COX or LOX metabolites), and the protective effect of an enriched EPA and DHA diet is lost with over-expression of sEH, an enzyme that degrades these bioactive fatty acid metabolites.
Stable analog of 17,18-EEQ (compound C21, (Z)-16-(2-(methylamino)-2-oxoacetamido)hexadec-11-enoic acid) having the following chemical structure:
contains oxamide functional group (as opposed to the epoxide group in 17, 18-EEQ) and maintains its potent bioactive functions but is unable to be degraded by sEH. See Falck J R et al. 17(R),18(S)-epoxyeicosatetraenoic acid, a potent eicosapentaenoic acid (EPA) derived regulator of cardiomyocyte contraction: structure-activity relationships and stable analogues. J Med Chem, 2011, 54(12), 4109-4118.
Administration of C21 significantly reduced CNV size compared to administration of control vehicle as assessed in both choroidal flat mounts and SD-OCT. C21 significantly reduced the extent of vascular leakage observed in these lesions. Increasing resistance to degradation of ω-3 LCPUFA metabolites as well as increasing their corresponding bioavailability enhance protection against CNV.
Systemic leukocyte recruitment to extravascular areas plays crucial role in the inflammatory process and the pathophysiology of several diseases. Leukocytes in the blood stream attach and roll on the surface of endothelial cells via interactions between adherent molecules and their ligands, such as intercellular cell-adhesion molecules (ICAM) or selectins, leading to leukocyte crawling and transendothelial migration. Leukocyte recruitment to CNV lesions is a critical step in increasing the severity of exudative AMD. Consuming an EPA and DHA enriched diet down-regulates CNV by reducing leukocyte infiltration into the CNV lesions. (See Yanai R, et al. (2014) Cytochrome P450-generated metabolites derived from omega-3 fatty acids attenuate neovascularization. Proc Natl Acad Sci USA 111(26):9603-9608; Mitroulis I, et al. (2015) Leukocyte integrins: role in leukocyte recruitment and as therapeutic targets in inflammatory disease. Pharmacol Ther 147:123-135; Ambati J & Fowler B J (2012) Mechanisms of age-related macular degeneration. Neuron 75(1):26-39; Noda K, et al. (2008) Vascular adhesion protein-1 blockade suppresses choroidal neovascularization. FASEB J 22(8):2928-2935).
Autoperfused Microflow Chamber assay was used to assess the impact of 17,18-EEQ and 19,20-EDP on systemic leukocyte recruitment during CNV development. The rolling velocity of peripheral blood leukocytes (PBLs) in the circulating blood was measured 3 days post CNV induction, as this reflects the peak of immune cell infiltration in this model.
The rolling velocity of PBLs on the chamber, which is coated with adherent molecules ICAM-1 and P-selectin, was significantly faster for mice administered 17,18-EEQ (1.48±0.16 μm/s) than for those administered PBS (0.94±0.06 μm/s). The rolling velocity of PBLs along the chamber was also significantly faster in mice administered 19,20-EDP (1.44±0.12 μm/s) than in mice administered PBS (0.94±0.06 μm/s). the functional down-regulation of ICAM-1 and P-selectin ligands on the surface of leukocytes in mice administered 17,18-EEQ and 19,20-EDP results in increased rolling velocity and decreased recruitment. To investigate the increase in ICAM-1-dependent rolling velocity of PBLs in mice administered 17,18-EEQ and 19,20-EDP, the expression of the ICAM-1 ligand, CD11b/CD18, on circulating leukocytes was measured. Flow cytometry analysis revealed that the surface expression level of CD11b on PBLs was significantly lower for mice administered 19,20-EDP, but not 17,18-EEQ, than for those administered PBS. On the contrary, the surface expression level of CD18 on PBLs was significantly lower for mice administered 17,18-EEQ, but not 19,20-EDP, than for those administered PBS. The effects of 17,18-EEQ and 19,20-EDP on the expression of adhesion molecules in CNV lesions were also examined. CNV lesions were collected using laser-capture microdissection. Mice administered 17,18-EEQ had significantly reduced mRNA levels of ICAM-1 and E-selectin in the CNV lesions 7 days post CNV induction compared to PBS injected controls. The increased rolling velocity of leukocytes from mice administered 17,18-EEQ and 19,20-EDP is attributable to the down-regulation of the expression of adhesion molecules (furthermore, each lipid metabolite has differential regulation on leukocytes or endothelial cells in CNV lesions).
The effect of CYP-derived eicosanoids of AA, EETs, on leukocyte recruitment was also determined.
The rolling velocity of PBLs along the chamber was significantly decreased for mice administered 8,9-EET (1.14±0.15 μm/s) than those administered PBS (2.30±0.13 μm/s). The rolling velocity of PBLs on the chamber was also significantly decreased in mice administered other regioisomeric EETs, 11,12-EET (1.41±0.45 μm/s) and 14,15-EET (1.41±0.11 μm/s), than in mice administered PBS (2.30±0.13 μm/s). The surface expression levels of CD11b on PBLs were unchanged for mice administered each EET compared to those administered PBS. Conversely, the surface expression levels of CD18 on PBLs were significantly higher for mice administered EETs compared to those administered PBS. Mice administered EETs had significantly increased levels of ICAM-1 mRNAs in the CNV lesions 7 days post CNV induction compared to PBS injected controls. In contrast, only 11,12-EET showed significant increase in the mRNA level of E-selectin compared to mice administered PBS. the decreased rolling velocity and increased recruitment of leukocytes from mice administered EETs are attributable to the up-regulation of the expression of adhesion molecules both on the surface of leukocytes and on endothelial cells in CNV lesions.
To elucidate the effect of CYP-derived fatty acids of EPA and DHA on CNV, the sEH inhibitor was utilized (1-trifluoromethoxyphenyl-3-(1-propionylpiperidin-4-yl) urea), which can block the degradation of 17,18-EEQ and 19,20-EDP by sEH (See Rose T E, et al. (2010) 1-Aryl-3-(1-acylpiperidin-4-yl)urea inhibitors of human and murine soluble epoxide hydrolase: structure-activity relationships, pharmacokinetics, and reduction of inflammatory pain. J Med Chem 53(19):7067-7075). Daily intraperitoneal injections of 17,18-EEQ and 19,20-EDP were administered to mice on a control diet with or without sEH inhibitor administered orally in the drinking water.
The administration of both 17,18-EEQ and 19,20-EDP alone significantly attenuated CNV size in choroidal flat mounts (

cData from Kitamura et al., (2015).
The results presented herein show that CYP-derived ω-3 metabolites modulate CNV disease progression and severity (e.g., using transgenic mice that either overexpress or lack CYP-specific enzymes, see, e.g., Examples 1-3). Overexpression of the monooxygenase CYP2C8 (see, e.g., Example 1) or genetic ablation or inhibition of the soluble epoxide hydrolase (sEH) enzyme (see, e.g., Example 2) leads to increased levels of EDP and EEQ with attenuated CNV development. In contrast, degradation of these CYP-derived metabolites was promoted by transgenic overexpression of she (see, e.g., Example 3), the protective effect against CNV was lost. As shown herein, endothelium-specific overexpression of human CYP2C8, coupled with a EPA and DHA enriched diet, markedly attenuated CNV development with a corresponding increase in the plasma levels of 17,18-EEQ and 19,20-EDP (See, e.g., Example 5). Pharmacological inhibition of sEH (see, e.g., Example 9) and chemical stabilization of 17,18-EEQ (see, e.g., Example 6) were shown to be effective in attenuating CNV development.
Without being bound by any particular theory, it is believed that the present application provides results showing contribution of the CYP monooxygenases and their metabolites on CNV, and the effect of CYP-dependent fatty acids on leukocyte recruitment during CNV formation. The results show that CYP-dependent fatty acids regulate the leukocyte rolling velocity by modulating the expression of adhesion molecules both on the surface of circulating leukocytes and in the CNV lesions. (see, e.g., Examples 7 and 8). The results presented in these examples show that 17,18-EEQ and 19,20-EDP down-regulate peripheral blood leukocyte adhesion ability. The interaction between β2-integrins on leukocytes and their endothelial ligands, such as ICAM-1 and E-selectin, is required for modulating adhesion, migration, and infiltration of leukocytes into inflammatory sites (41). Integrin CD11b/CD18, which consists of a heterodimer of the αM (CD11b) and β2 (CD18) subunits, is the most crucial β2-integrin for leukocyte recruitment (41). The present data shows that 17,18-EEQ and 19,20-EDP reduced CD11b/CD18 expression in PBLs, and that 17,18-EEQ reduced ICAM-1 and E-selectin expression in endothelial cells in CNV lesions (see, e.g., Example 7). These findings indicate that the inhibitory effect of 17,18-EEQ and 19,20-EDP on CNV may be due to their inhibitory effect on leukocyte recruitment by reducing the expression of adherent molecules on both leukocytes and endothelial cells.
The major dietary ω-6 LCPUFA is arachidonic acid (AA). The results presented herein show that dietary intake of AA (see, e.g., Example 1-3) and direct administration of its epoxy metabolites (EETs) (see, e.g., Example 4) did not have a significant effect on CNV development. Rather, EETs promoted PBL adhesion, increased CD18 expression in PBLs, and increased ICAM-1 and E-selectin expression in endothelial cells in CNV lesions (see, e.g., Example 8). These results are consistent with the general idea that ω-6 LCPUFAs and their metabolites are pro-inflammatory as opposed to ω-3 LCPUFAs and their metabolites.
