BACKGROUND OF THE INVENTION

Field of the Invention

[0001] The present disclosure is directed to novel heterocyclic prolinamide derivatives, pharmaceutical compositions containing such novel compounds, as well as methods for preventing and treating age-related macular degeneration (AMD) and related diseases of the eye.

Description of the Related Art

[0002] Age-related macular degeneration (AMD) is the leading cause of severe loss of vision in people over the age of 60. Age is the major risk factor for the onset of AMD: the likelihood of developing AMD triples after age 55. Many factors, however, contribute to the likelihood that an individual will develop AMD.

[0003] As summarized in WO2001/006262, "environmental" conditions may modulate the rate at which an individual develops AMD or the severity of the disease. Light exposure has been proposed as a possible risk factor, since AMD most severely affects the macula, where light exposure is high. (See Young, R. W. (1988), Surv. Ophthalmol. 32(4), 252- 69; Taylor, H. R. et al, (1990), Trans. Amer. Ophthalmol. Soc. 88, 163-73; Schalch W. (1992), Exs, 62, 280-98). The amount of time spent outdoors is associated with increased risk of choroidal neovascularization in men, and wearing hats and/or sunglasses is associated with a decreased incidence of soft drusen (Cruickshanks, K. et al, (1993), Arch. Ophthalmol., I l l, 514-518). Accidental exposure to microwave irradiation has also been shown to be associated with the development of numerous drusen (Lim, J. et al., (1993), Retina. 13, 230-3). Cataract removal and light iris pigmentation has also been reported as a risk factor in some studies (Sandberg, M. et al, (1994), Invest. Ophthalmol. Vis. Sci. 35(6), 2734-40). This suggests that: 1) eyes prone to cataracts may be more likely to develop AMD; 2) the surgical stress of cataract removal may result in increased risk of AMD, due to inflammation or other surgically-induced factors; or 3) cataracts prevent excessive light exposure from falling on the macula, and are in some way prophylactic for AMD. While it is possible that dark iris pigmentation may protect the macula from light damage, it is difficult to distinguish between iris pigmentation alone and other, co-segregating genetic factors which may be actual risk factors.

[0004] Smoking, gender (women are at greater risk), obesity, and repeated exposure to UV radiation also increase the risk of AMD.

[0005] More recently, a number of HTRA1 single nucleotide polymorphs (SNP) have been found to be associated with an increased risk of AMD. See, for example, WO2008/013893A2, WO2008/067040A2 and WO2008/094370A2. These SNP's include rsl 1200638, rsl0490924, rs3750848, rs3793917 and rs932275. In particular, the risk allele rsl 1200638, was found to be associated with increased HTRA1 mRNA and protein expression, and HTRA1 is present in drusen in patients with AMD. (See Dewan et al., (2006), Science 314:989-992; Yang et al., (2006), Science 314:992-993). These disclosures provide evidence that HTRA1 is an important factor in AMD and the progression thereof.

[0006] In broad terms, there are two forms of AMD: dry AMD and wet AMD. The dry form is the more common, and accounts for 85-90% of the patients with AMD, and does not typically result in blindness. In dry AMD, (also called non-neovascular AMD or non-exudative AMD) drusen appear in the macula of the eye, the cells in the macula die, and vision becomes blurry. Dry AMD can progress in three stages: 1) early, 2) intermediate, and 3) advanced dry AMD. Dry AMD can also progress into wet AMD during any of these stages.

[0007] Wet AMD (also called neovascular or exudative AMD), is associated with pathologic posterior segment neovascularization. The posterior segment neovascularization (PSNV) found in exudative AMD is characterized as pathologic choroidal neovascularization. Leakage from abnormal blood vessels forming in this process damages the macula and impairs vision, eventually leading to blindness.

[0008] The end stage of AMD is characterized by a complete degeneration of the neurosensory retina and of the underlying retinal pigment epithelium in the macular area. Advanced stages of AMD can be subdivided into geographic atrophy (GA) and exudative AMD. Geographic atrophy is characterized by progressive atrophy of the retinal pigment epithelium (RPE). While GA is typically considered less severe than the exudative AMD because its onset is less sudden, to date no treatment has been effective at halting or slowing its progression.

[0009] Currently, treatment of dry AMD includes the administration of antioxidant vitamins and/or zinc. For example, one study at the National Eye Institute assessed a composition comprising vitamin C, β-carotene, zinc oxide and cupric oxide.

[0010] Treatment of wet AMD is also wanting. Available drug therapies include: bevacizumab (Avastin®, Genentech, CA), ranibizumab (Lucentis®, Genentech, CA), pegaptanib (Macugen® Bausch & Lomb, NJ), and aflibercept (Eylea®, Regeneron, NY). In each instance, the medication is injected into the eye. Injections may be repeated every four to eight weeks to maintain the beneficial effect of the medication. Those with a positive result may partially recover vision as the blood vessels shrink and the fluid under the retina is absorbed, allowing retinal cells to regain some function.

[0011] Pharmacologic therapy for the treatment of macular edema associated with AMD is lacking. The current standard of care is laser photocoagulation, which is used to stabilize or resolve macular edema and retard the progression to later stage disease. Laser photocoagulation may reduce retinal ischemia by destroying healthy tissue and thereby decreasing metabolic demand; it also may modulate the expression and production of various cytokine and trophic factors. There are no current treatments for preventing loss of vision after dry AMD enters an advanced stage. There are also no definitive methods for preventing progression of dry AMD to an advanced stage, other than by avoiding and/or reducing risk factors and using dietary supplements, which cannot guarantee or be relied on to stop AMD progression. Thus, there is a need for therapeutics that can treat dry AMD and prevent progression of dry to wet AMD.

[0012] The compound (l- {3-cyclohexyl-2-[naphthalene-2-carbonyl)-amino]- propionyl}-pyrrolidine-2-carboxylic acid [5-(3-cyclohexyl-ureido)-l-dihydroxyboranyl-pentyl]- amide is disclosed in Grau, S. et. al., (2006), J. Biol. Chem., 281(10):6124-6129 and in WO2012/078540 (identified therein as NVP-LB976) as an inhibitor of HTRA1.

[0013] In addition to AMD, a number of publications have described a potential role of HTRAl and disease, including retinal angiomatous proliferation (Ohkuma, Y., et al, (2014) Clin. Ophthalmol, 8: 143-8), foveomacular proliferation (Chowers, I, et al, (2015) Progress in Retinal and Eye Research, 47:64-85), musculoskeletal diseases, including osteoarthritis, spinal disk degeneration rheumatoid arthritis, muscular dystrophy and osteoporosis (Taiden, A.N. and Richards, P.J. (2013) Am. J. Pathology, 182(5): 1482-8), and treatment of autologous chondrocytes prior to intraarticular implantation (Ollitrault, D. et al., (2015) Tissue Engineering, Part C Methods, 21(2): 133-47). An HTRAl inhibitor thus may demonstrate a therapeutic benefit in these additional indications.

Definitions

[0047] nless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise. In the event that there are a plurality of definitions for a term herein, those in this section prevail unless stated otherwise.

[0048] The term "patient" includes mammals such as mice, rats, cows, sheep, pigs, rabbits, goats, horses, monkeys, dogs, cats, and humans. [0049] The term "halo" or "halogen" refers to any radical of fluorine, chlorine, bromine or iodine.

[0050] The term "alkyl" refers to a saturated hydrocarbon chain that may be a straight chain or branched chain, containing the indicated number of carbon atoms. For example, Ci- ₆ alkyl indicates that the group may have from 1 to 6 (inclusive) carbon atoms in it. In some embodiments, an alkyl is a Ci- ₆ alkyl which represents a straight-chain or branched saturated hydrocarbon radical having 1 to 6 carbon atoms. Examples of alkyl include without limitation methyl, ethyl, ^-propyl, isopropyl, w-butyl, isobutyl, sec-butyl, and tert-butyl. The notation "Co- _n alkyl" indicates the absence of an alkyl moiety, or the presence of an alkyl moiety having 1 to n carbon atoms. Thus, for example, the term "Co- ₆ alkyl-R ⁵ " indicates that the R ⁵ group is attached directly to the parent moiety, or that there is an intervening alkyl group of 1 to 6 carbon atoms between R ⁵ and the parent moiety; such an intervening group may be, for example, -CH ₂ -, -CH2CH2-, -CH(CH ₃ )- and -C(CH ₃ ) ₂ -.

[0051] The term "haloalkyl" refers to an alkyl group in which at least one hydrogen atom is replaced by halo. In some embodiments, more than one hydrogen atom (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, or 14) are replaced by halo. In these embodiments, the hydrogen atoms can each be replaced by the same halogen (e.g., fluoro) or the hydrogen atoms can be replaced by a combination of different halogens (e.g., fluoro and chloro). "Haloalkyl" also includes alkyl moieties in which all hydrogens have been replaced by halo (sometimes referred to herein as perhaloalkyl, e.g., perfluoroalkyl, such as trifluoromethyl).

[0052] As referred to herein, the term "alkoxy" refers to a group of formula -O-(alkyl). Alkoxy can be, for example, methoxy, ethoxy, propoxy, isopropoxy, butoxy, iso- butoxy, sec-butoxy, pentoxy, 2-pentoxy, 3-pentoxy, or hexyloxy. Likewise, the term "thioalkoxy" refers to a group of formula -S-(alkyl). The terms "haloalkoxy" and "thiohaloalkoxy" refer to -O-(haloalkyl) and -S-(haloalkyl), respectively. The term "sulfhydryl" refers to -SH.

[0053] The term "aralkyl" refers to an alkyl moiety in which an alkyl hydrogen atom is replaced by an aryl group. One of the carbons of the alkyl moiety serves as the point of attachment of the aralkyl group to another moiety. Non-limiting examples of "aralkyl" include benzyl, 2-phenylethyl, and 3-phenylpropyl groups. [0054] The term "alkenyl" refers to a straight or branched hydrocarbon chain containing the indicated number of carbon atoms and having one or more carbon-carbon double bonds. Alkenyl groups can include, e.g., vinyl, allyl, 1-butenyl, and 2-hexenyl. In some embodiments, an alkenyl is a C2- ₆ alkenyl.

Compound Forms and Salts

[0070] The compounds of this disclosure may contain one or more asymmetric centers and thus occur as racemates and racemic mixtures, enantiomerically enriched mixtures, single enantiomers, individual diastereomers and diastereomeric mixtures. The compounds of the present disclosure may, either by nature of asymmetric centers or by restricted rotation, be present in the form of isomers (e.g., enantiomers, diastereomers).

[0071] It will also be appreciated that when two or more asymmetric centers are present in the compounds of the disclosure, several diastereomers and enantiomers of the exemplified structures will often be possible, and that pure diastereomers and pure enantiomers represent preferred embodiments. It is intended that pure stereoisomers, pure diastereomers, pure enantiomers, and mixtures thereof, are within the scope of the disclosure.

[0072] All isomers, whether separated, pure, partially pure, or in racemic mixture, of the compounds of this disclosure are encompassed within the scope of this disclosure. The purification of said isomers and the separation of said isomeric mixtures may be accomplished by standard techniques known in the art. For example, diastereomeric mixtures can be separated into the individual isomers by chromatographic processes or crystallization, and racemates can be separated into the respective enantiomers either by chromatographic processes on chiral phases or by resolution.

All such isomeric forms of such compounds are expressly included in the present disclosure.

[0074] The compounds of the present disclosure include the compounds themselves, as well as their salts, solvate, solvate of the salt and their prodrugs, if applicable. Salts for the purposes of the present disclosure are preferably pharmaceutically acceptable salts of the compounds according to the present disclosure. Salts which are not themselves suitable for pharmaceutical uses but can be used, for example, for isolation or purification of the compounds according to the disclosure are also included. A salt, for example, can be formed between an anion and a positively charged substituent (e.g., amino) on a compound described herein. Suitable anions include chloride, bromide, iodide, sulfate, nitrate, phosphate, citrate, methanesulfonate, trifluoroacetate, and acetate. Likewise, a salt can also be formed between a cation and a negatively charged substituent (e.g., carboxylate) on a compound described herein. Suitable cations include sodium ion, potassium ion, magnesium ion, calcium ion, and an ammonium cation such as tetramethylammonium ion.

[0075] As used herein, "pharmaceutically acceptable salts" refer to derivatives wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. When the compound of the present disclosure is basic, pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfonic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, benzenesulfonic, toluenesulfonic, naphthalenedisulfonic, methanesulfonic, ethanesulfonic, ethanedisulfonic, camphorsulfonic, gluconic, mandelic, mucic, pantothenic, oxalic, isethionic, and the like.

[0077] Lists of suitable salts may be found in Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., 1985, p. 1418; S. M. Berge et al, "Pharmaceutical Salts", J. Pharm. Sci. 1977, 66, 1-19; and "Pharmaceutical Salts: Properties, Selection, and Use. A Handbook"; Wermuth, C. G. and Stahl, P. H. (eds.) Verlag Helvetica Chimica Acta, Zurich, 2002 [ISBN 3-906390-26-8]; each of which is incorporated herein by reference in its entirety.

[0078] Solvates in the context of the present disclosure are designated as those forms of the compounds according to the present disclosure which form a complex in the solid or liquid state by stoichiometric coordination with solvent molecules. Hydrates are a specific form of solvates, in which the coordination takes place with water. Hydrates are preferred solvates in the context of the present disclosure. The formation of solvates is described in greater detail in "Solvents and Solvent Effects in Organic Chemistry"; Reichardt, C. and Welton T.; John Wiley & Sons, 2011 [ISBN: 978-3-527-32473-6], the contents of which is incorporated herein by reference in its entirety. A person of ordinary skill in the art would recognize the solvates of the present disclosure.

[0079] The present disclosure also encompasses all suitable isotopic variants of the compounds according to the present disclosure, whether radioactive or not. An isotopic variant of a compound according to the present disclosure is understood to mean a compound in which at least one atom within the compound according to the present disclosure has been exchanged for another atom of the same atomic number, but with a different atomic mass than the atomic mass which usually or predominantly occurs in nature. Examples of isotopes which can be incorporated into a compound according to the present disclosure are those of hydrogen, carbon, nitrogen, oxygen, fluorine, chlorine, bromine and iodine, such as ² H (deuterium), ³ H (tritium), ¹³ C, ¹⁴ C, ¹⁵ N, ¹⁷ 0, ¹⁸ 0, ¹⁸ F, ³⁶ C1, ⁸² Br, ¹²³ I, ¹²⁴ I, ¹²⁵ I, ¹²⁹ I and ¹³¹ I. Particular isotopic variants of a compound according to the present disclosure, especially those in which one or more radioactive isotopes have been incorporated, may be beneficial, for example, for the examination of the mechanism of action or of the active compound distribution in the body. Due to comparatively

3 14 18 easy preparability and detectability, especially compounds labelled with H, C and/or F isotopes are suitable for this purpose. In addition, the incorporation of isotopes, for example of deuterium, can lead to particular therapeutic benefits as a consequence of greater metabolic stability of the compound, for example an extension of the half-life in the body or a reduction in the active dose required. Such modifications of the compounds according to the present disclosure may therefore in some cases also constitute a preferred embodiment of the present disclosure. In some embodiments, hydrogen atoms of the compounds described herein may be replaced with deuterium atoms. Isotopic variants of the compounds according to the present disclosure can be prepared by processes known to those skilled in the art, for example by the methods described below and the methods described in the working examples, by using corresponding isotopic modifications of the particular reagents and/or starting compounds therein.

[0080] The present disclosure includes within its scope prodrugs of the compounds of Formula I. Prodrugs are generally drug precursors that, following administration to a subject are converted to an active, or a more active species via some process, such as conversion by chemical hydrolysis or a metabolic pathway. Thus, in the methods of treatment of the present disclosure, the terms "administration of or "administering a" compound shall encompass the treatment of the various conditions described with the compound specifically disclosed or with a compound which may not be specifically disclosed, but which converts to the specified compound in vivo after administration to the patient. Conventional procedures for the selection and preparation of suitable prodrug derivatives are described, for example, in "Design of Prodrugs," ed. H. Bundgaard, Elsevier, 1985 (Amsterdam, NL). Examples of prodrugs include Ci-6 alkyl esters of carboxylic acid groups and esters of boronic acids, which, upon administration to a subject, are capable of providing active compounds.

[0081] Esters of boronic acids are illustrated by Formula II:

Pharmaceutical Compositions

[0085] The term "pharmaceutical composition" as used herein is intended to encompass a product comprising the active ingredient(s), and the inert ingredient(s) that make up the carrier, as well as any product which results, directly or indirectly, from combination, complexation or aggregation of any two or more of the ingredients, or from dissociation of one or more of the ingredients, or from other types of reactions or interactions of one or more of the ingredients. Accordingly, the pharmaceutical compositions of the present disclosure encompass any composition made by admixing a compound of the present disclosure, or a pharmaceutically acceptable salt, or solvate or solvate of the salt thereof, and a pharmaceutically acceptable carrier.

[0086] The term "pharmaceutically acceptable carrier" refers to a carrier or an adjuvant that may be administered to a patient, together with a compound of the present disclosure, or a pharmaceutically acceptable salt, solvate, salt of the solvate or prodrug thereof, and which does not destroy the pharmacological activity thereof and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the compound.

[0087] The amount administered depends on the compound formulation, route of administration, etc. and is generally empirically determined in routine trials, and variations will necessarily occur depending on the target, the host, and the route of administration, etc. Generally, the quantity of active compound in a unit dose of preparation may be varied or adjusted from about 1, 3, 10 or 30 to about 30, 100, 300 or 1000 mg, according to the particular application. For convenience, the total daily dosage may be divided and administered in portions during the day if desired.

Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

[0089] These pharmaceutical compositions may also contain adjuvants such as preservative, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of micro-organisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include isotonic agents such as sugars, sodium chloride, and the like. Prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents that delay absorption such as aluminium monostearate and gelatin. If desired, and for more effective distribution, the compounds can be incorporated into slow release or targeted delivery systems such as polymer matrices, liposomes, and microspheres.

[0090] The pharmaceutical compositions that are injectable formulations can be sterilised, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilising agents in the form of sterile solid pharmaceutical compositions that can be dissolved or dispersed in sterile water or other sterile injectable medium just prior to use.

[0091] Solid dosage forms of the instant pharmaceutical compositions for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active compound is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidone, sucrose, and acacia, c) humectants such as glycerol, d) disintegrating agents such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, e) solution retarding agents such as paraffin, f) absorption accelerators such as quaternary ammonium compounds, g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, h) absorbents such as kaolin and bentonite clay, and i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof. In the case of capsules, tablets and pills, the dosage form may also comprise buffering agents.

[0092] Solid pharmaceutical compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.

[0093] The solid dosage forms of the instant pharmaceutical compositions of tablets, dragees, capsules, pills, and granules can be prepared with coatings and shells such as enteric coatings and other coatings well known in the pharmaceutical formulating art. They may optionally contain opacifying agents and can also be of a formulation that they release the active ingredient(s) only, or preferentially, in a certain part of the intestinal tract, optionally, in a delayed manner. Examples of embedding pharmaceutical compositions which can be used include polymeric substances and waxes.

[0094] The active compounds can also be in microencapsulated form, if appropriate, with one or more of the above-mentioned excipients.

[0095] Liquid dosage forms of the instant pharmaceutical compositions for oral administration include pharmaceutically acceptable emulsions, solutions, suspensions, syrups and elixirs. In addition to the active compounds, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, dimethyl formamide, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofurfuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. [0096] Besides inert diluents, the oral pharmaceutical compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavouring, and perfuming agents.

[0097] Suspensions of the instant compounds, in addition to the active compounds, may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminium metahydroxide, bentonite, agar-agar, and tragacanth, and mixtures thereof.

[0098] Pharmaceutical compositions for rectal or vaginal administration are preferably suppositories which can be prepared by mixing the compounds with suitable non- irritating excipients or carriers such as cocoa butter, polyethylene glycol or a suppository wax which are solid at room temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active compound.

[0099] Dosage forms for topical administration of a compound or pharmaceutical composition of the present disclosure include powders, patches, sprays, ointments and inhalants. The active compound is mixed under sterile conditions with a pharmaceutically acceptable carrier and any needed preservatives, buffers, or propellants which may be required.

[0100] Dosage forms for application to the eye include solutions, suspensions, ointments, gels, emulsions, strips, inserts such as contact lenses, and implants, which may be administered topically, intravitreally, perioccularly, and the like.

[0103] 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, dosage form, and/or route of administration. 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, 219-244 (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 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 the present disclosure 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.

[0104] 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, and the judgment of the treating physician.

[0105] Dosage forms include from about 0.001 milligrams to about 2,000 milligrams (including, from about 0.001 milligrams to about 1,000 milligrams, from about 0.001 milligrams to about 500 milligrams, from about 0.01 milligrams to about 250 milligrams, from about 0.01 milligrams to about 100 milligrams, from about 0.05 milligrams to about 50 milligrams, and from about 0.1 milligrams to about 25 milligrams) of a compound of Formula I (and/or a compound of any of the other formulae described herein) or a salt (e.g., a pharmaceutically acceptable salt) thereof as defined anywhere herein. The dosage forms can further include a pharmaceutically acceptable carrier and/or an additional therapeutic agent.

[0106] With regard to ophthalmic preparation, because AMD and related diseases (including dry-AMD, Wet-AMD, geographic atrophy, diabetic retinopathy, retinopathy of prematurity, polypoidal choroidal vasculopathy, and degeneration of retinal or photoreceptor cells) primarily afflict the back of the eye, local administration such as topical administration, trans-scleral drug delivery and intravitreal administration may be preferable over systemic administration. Intravitreal administration can be further divided into intravitreal injection and intravitreal implants. Of these, intravitreal injection appears to be the most widely used. Products utilizing intravitreal injection include Trivaris® (triamcinolone acetonide), Triescence® (triamcinolone acetonide, Alcon Fort Worth, TX), Macugen®(pegaptanib sodium, Bausch and Lomb, Rochester, NY), Lucentis® (ranibizumab injection, Genentech, South San Francisco, CA), Ozurdex® (dexamethasone, Allergan, Inc., Irvine, CA) and Iluvien® (flucinolone acetonide, Alimera Sciences, Alpharetta, GA). The preferred dosage range for local administration to the back of the eye ranges from 0.001 mg to 100 mg (including from about 0.01 milligrams to about 500 milligrams, from about 0.05 milligrams to about 250 milligrams, from about 0.05 milligrams to about 100 milligrams, from about 0.1 milligrams to about 50 milligrams, from about 0.1 milligrams to about 25 milligrams, and from about 0.1 milligrams to about 10 milligrams).

[0107] For the treatment and/or prevention of ocular disorders, as described above, the preferred route for administering the compounds of the present disclosure is topically at the eye or by an ocular drug delivery system. Intraocular injections are another way to administer the compounds of the present disclosure that is suitable for such purposes.

[0108] Delivery to areas within the eye can be accomplished by injection, employing a cannula or another invasive device designed to introduce precisely metered amounts of a desired formulation to a particular compartment or tissue within the eye (e.g., posterior chamber or retina). An intraocular injection may be into the vitreous (intravitreal), under the conjunctiva (subconjunctival), behind the eye (retrobulbar), into the sclera, or under the Capsule of Tenon (sub-Tenon), and may be in a depot form. Other intraocular routes of administration and injection sites and forms are also contemplated and are within the scope of the present disclosure.

[0109] The compounds according to the present disclosure may be formulated in a manner known to those skilled in the art so as to give adequate delivery to the back of the eye, which may be by regular dosing, such as with eye drops, or by using a delivery system to give a controlled release, such as slow release, of the compounds according to the present disclosure.

[0110] Preferred ocular formulations for the compounds of the present disclosure include aqueous solutions, suspensions or gels of these compounds in the form of drops of liquid, liquid washes, sprays, ointments or gels, in a mixture with excipients suitable for the manufacture and use of such application forms. Alternatively, the compounds of the present disclosure may be applied to the eye via liposomes or other ocular delivery systems that are known in the art.

[0111] Appropriate dosage levels may be determined by any suitable method known to one skilled in the art of treating eye diseases. Preferably, the active substance is administered at a frequency of 1 to 4 times per day for topical administration, or less often if a drug delivery system is used. Typically, an ocular formulation intended for topical application contains the active ingredient in a concentration range of about 0.001% to 10%.

[0112] Nevertheless, actual dosage levels and time course of administration of the active ingredients in the pharmaceutical compositions of the present disclosure may be varied so as to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition and mode of administration, without being toxic to the patient. It may therefore be necessary where appropriate to deviate from the stated amounts, in particular as a function of age, gender, body weight, diet and general health status of the patient, route of administration, individual response to the active ingredient, nature of the preparation, and time or interval over which administration takes place. Thus, it may be satisfactory in some cases to manage with less than the aforementioned minimum amount, whereas in other cases the stated upper limit must be exceeded. It may in the event of administration of larger amounts be advisable to divide these into multiple individual doses spread over the day.

[0113] In one aspect the compounds of the present disclosure may be co-administered with one or more additional agents. The additional agents include, but are not limited to Acuvail® (ketorolac tromethamine ophthalmic solution), AK-Con-A®/OcuHist® (pheniramine maleate-naphazoline HC1, ophthalmic solution), Akten® (lidocaine HC1 ophthalmic gel), Alamast® (pemirolast potassium ophthalmic solution), Alphagan® (brimonidine tartrate ophthalmic solution), Bepreve® (bepotastine besilate ophthalmic solution), Besivance® (besifloxacin ophthalmic suspension), Betaxon® (levobetaxolol HC1 ophthalmic suspension), Cosopt® (dorzolamide HC1 - timolol maleate, ophthalmic solution), Cystaran® (cysteamine HC1 ophthalmic solution), Durezol® (difluprednate ophthalmic emulsion), Eylea® (aflibercept intravitreal injection), Jetrea® (ocriplasmin intravitreal injection), Lotemax® (loteprednol etabonate ophthalmic suspension), Lucentis® (ranibizumab injection), Lumigan® (bimatoprost ophthalmic solution), Macugen® (pegaptanib intravitreal injection), Ocuflox® (ofloxacin ophthalmic solution), Omidria® (phenylephrine and ketorolac injection), Ozurdex® (dexamethasone intravitreal implant), Quixin® (levofloxacin ophthalmic solution), Rescula® (unoprostone isopropyl ophthalmic solution 0.15%), Restasis® (cyclosporine ophthalmic emulsion), Salagen® (pilocarpine HC1 tablets), Travatan® (travoprost ophthalmic solution), Valcyte® (valganciclovir HC1 tablets and oral solution), Vistide® (cidofovir tablets), Visudyne® (verteporfin injection), Vitrasert® (ganciclovir implant), Vitravene® (fomivirsen injection), Zioptan® (tafluprost ophthalmic solution), Zirgan® (ganciclovir ophthalmic gel), and Zymaxid® (gatifloxacin ophthalmic solution). Furthermore the compounds of the disclosure may be co-administered with one or more inhibitors of VEGF-mediated angiogenesis, such as, for example, ACTB-1003 (Edding Pharm, CN), apatinib, axitinib, bevacizumab, bevasiranib, BMS- 690514 (Bristol-Myers Squibb (BMS), NY), bnvanib, cediranib, CT-322 (Adnexus/BMS, MA), dovitinib, lenvatinib, foretinib, KH-902/conbercept (approved in CN for exudative macular degeneration), linifanib, MGCD-265 (Mirati Therapeutics, CA), motesanib, elpamotide, pazopanib, pegaptanib, ranibizumab, regorafenib, ruboxystaurin, sorafenib, SU-14813 (Pfizer, CT), sunitinib, telatinib, TG- 100801, tivozanib, TSU-68 (Taiho Pharmaceuticals, JP), vandetanib, vargatef, vatalanib and Carbometyx® (cabozantinib tablets, Exelixis, CA), or with inhibitors of other signaling pathways, such as disulfiram, fenretinide, mecamylamine, PF-04523655 (Pfizer, CT), sonepcizumab, tandospirone and volociximab.

[0114] Additional agents which may be utilized for co-administration include: known vitamins and antioxidants such as AREDS/AREDS2 (supplements used in Age-Related Eye Disease Study/Study 2, National Eye Institute, US), omega-3 fatty acids, lutein, zeaxanthin, vitamin A; visual-cycle modulators such as emixustat (ACU-4429, Acucela, WA); anti-inflammatory agents such as Illuvien® (fluocinolone acetonide), sirolimus, Triesence® /Trivaris® (triamcinolone acetonide); complement modulators such as lampalizumab, Soliris® (eculizumab, Alexion, CT); amyloid- modulators such as GSK933776 (GlaxosmithKline, PA), RN6G (PF-04382923, Pfizer, CT) and platelet-derived growth factor modulators such as, for example, Fovista® (pegpleranib, Ophthotech, NY).

[0115] In certain embodiments, the additional agents may be administered separately (e.g., sequentially; on different overlapping schedules), as part of a multiple dose regimen, from the compounds of the present disclosure (e.g., one or more compounds of Formula (I) and/or a compound of any of the other formulae, including any subgenera or specific compounds thereof). In other embodiments, these agents may be part of a single dosage form, mixed together with the compounds of the present disclosure 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 as that of one or more compounds of Formula (I) (and/or a compound of any of the other formulae, including any subgenera or specific compounds thereof) are administered (e.g., simultaneously with the administration of one or more compounds of Formula (I) (and/or a compound of any of the other formulae, including any subgenera or specific compounds thereof)). When the compositions of the present disclosure include 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 can 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.

[0116] The compositions of the present disclosure 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.

[0117] The compositions of the present disclosure 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 and then combined with emulsifying and/or suspending agents. If desired, certain sweetening and/or flavoring and/or coloring agents may be added.

Biological Function

[0118] The utility of the present disclosure can be demonstrated by one or more of the following methods or other methods known in the art:

Full Length HTRA1 Assay

[0119] Serial dilutions (1/3) from 1000 μΜ down to 0.051 μΜ of test compounds were prepared in dimethyl sulfoxide (DMSO). Then 2 μL of solution from each dilution were added to 100 μL of 4 nM full-length human His-HTRAl in assay buffer (50 mM Tns, pH 7.5, 200 niM NaCl and 0.25% 3-[(3-cholamidopropyl)dimethylammonio]-l -propanesulfonate or CHAPS) in white non-binding 96-well plates. The assay solutions were mixed for 5 seconds on a shaker plate and incubated for 10 minutes at room temperature. Mca-H ₂ 0PT (Mca-Ile-Arg-Arg-Val-Ser-Tyr-Ser-Phe-Lys(Dnp)-Lys-OH trifluoroacetate salt)

(Mca = 7-methoxycoumarin-4-acetic acid; Dnp = dinitrophenyl) (5 μΜ) in 100 μΙ_, of assay buffer was added to the assay solutions. The reaction mixture was shaken for 5 seconds on a shaker plate and cleavage of Mca-H ₂ 0PT was monitored by spectrofluorometry (SpectraMax M3 by Molecular Devices, CA) for 10 minutes (Εχλ = 330 nm; Έτηλ = 420 nm). Percent inhibition was calculated by fitting values to a standard mathematical model for determining the dose response curve.

General Synthetic Scheme

[0121] In some embodiments, compounds described herein can be prepared as outlined in the following general synthetic schemes. These compounds may be viewed as consisting of four units as shown in the general structure: A - the R ^x -Y group, B - an a-amino acyl group, C - the prolyl group, and D - an aminoheterocyclic group; and this shorthand notation is used below to refer to such units and the various combinations thereof. All the variables in the general structure and in the synthetic schemes are, unless otherwise specified, as defined in the claims; the triazole substituent R is a substituent for the heteroaryl group, as defined in the claims. General Structure

Method I: Synthesis of aminoheterocyclic 2-hydroxyacetamides (1-6, D)

[0122] The reduction of a suitably protected (e.g., Boc-protected) aminoheterocyclic carboxylic acid (I-l) to the corresponding alcohol (1-2) using a reducing agent such as LAH, followed by oxidation with, for example, DMP provides the aminoheterocyclic aldehyde (1-3). Alternatively, the protected aminoheterocyclic carboxylic acid (I-l) is coupled to N.O-dimethylhydroxylamine and the resulting N-methoxy-N- methylacetamide (1-7) is reduced, using for example LAH, to afford the corresponding aminoheterocyclic aldehyde (1-3). The aldehyde is treated with KCN and NaHSC to give the desired cyanohydrin (1-4), which can then be hydrolyzed to the protected hydroxyacetamide (1-5) using standard basic conditions such as K2CO3/H ₂ O ₂ or urea hydrogen peroxide/K^CC (similar to method as in Li, Yun-Long, et ah, PCT Int. Appl. 2015191677, Dec 17, 2015). The hydroxyacetamide (1-5) is then deprotected (e.g. using HCl for Boc) to provide the aminoheterocyclic 2-hydroxyacetamide (1-6, D). Alternatively, the cyanohydrins (1-4) can be hydrolyzed using cone. HCl to provide the deprotected aminoheterocyclic 2-hydroxyacetamide (1-6) in one step.

[0123] The hydroxyl amides containing cyclic ethers, cyclic sulfones or cyclic amides are oxidized to the corresponding ketoamides using a number of oxidative reagents such as DMP or IBX. The hydroxyamides containing a thio ether necessitate protection of the sulfide (e.g. via the addition of stoichiometric Pd/C or copper(II) acetate) to avoid oxidation of the thio ether to the corresponding sulfoxide.

Method II: Synthesis of 4-triazoloproline intermediates (Π-5, B-C)

[0124] The alcohol moiety of a protected 4-hydroxyproline ester (II-l) is converted to a mesylate with MsCl and then reacted with NaN ₃ to afford 4-azidoproline (II-2). The azide intermediate is treated with substituted acetylenes in the presence of metal catalysis to afford the triazole adduct (Π-3; see Boren, B. C, et al. J. Am. Chem. Soc. 2008, 130, 8923-8930 and Himo, F., et al. J. Am. Chem. Soc. 2005, 127, 210-216). Deprotection of the proline ring nitrogen, followed by coupling with another suitably protected amino acid using standard amide coupling conditions provides the triazoloproline (Π-4). Hydrolysis of the ester under standard basic conditions such as LiOH affords the triazoloproline intermediate (Π-5, B-C).

Method III: Synthesis of 4-triazoloproline intermediates (ΠΙ-3, A-B-C)

[0125] Alternatively, the azidoproline derivative (Π-2) can be directly deprotected with HCl and then coupled with a suitably protected amino acid using standard amide coupling conditions to form the azidoproline intermediate (ΠΙ-l). Deprotection with HCl followed by reaction with a carboxylic acid (or equivalent) using standard amide coupling conditions provides the N-acyl azidoproline intermediate (ΙΠ-2). A [3+2] cycloaddition of this azide with a substituted acetylene using a metal catalysis as in Boren, B. C, supra, or Himo, F. supra, followed by hydrolysis under standard basic conditions such as LiOH gives the corresponding triazoloproline intermediate (ΙΠ-3, A-B-C).

111-3 A-B-C Method IV: Synthesis of heterocyclic ketoamides intermediates (IV-3, B-C-D)

[0126] The protected B-C triazoloproline acid (Π-5) is coupled with aminoheterocyclic 2-hydroxypropanamide (1-6, D) using standard amide coupling procedures to provide the protected hydroxyamide intermediate (IV-1). Oxidation of the hydroxyamide (IV-1) provides the corresponding ketoamide (IV-2). Hydroxyamides containing cyclic ethers, cyclic sulfones or cyclic amides can be oxidized to the corresponding ketoamides using an oxidative reagent such as DMP or IBX. For hydroxyamides containing a thioether, a stoichiometric amount of Pd/C or copper(II) acetate is added to avoid oxidation of the thioether to the corresponding sulfoxide. The Boc group can be deprotected using HC1 to give the amino ketoamides (IV-3, B-C-D).

for X = S: DMP/Cu ²⁺ or DMP/Pd

Method V: Synthesis of product ketoamides (V-l, B-C-D to A-B-C-D)

[0127] The B-C-D amino ketoamide (IV-3) can be coupled with carboxylic acid, acid chloride, sulfonyl chloride or isocyanate using standard procedures to form the amide linked, sulfonamide linked or urea linked ketoamide (V-l, A-B-C-D).

IV-3 B-C-D V-1 A-B-C-D

Method VI: Synthesis of product ketoamides (VI-2, A-B-C to A-B-C-D)

[0128] Triazoloproline carboxylic acid (ΙΠ-3, A-B-C) can be coupled to the amino hydroxyamide (1-6, D) using standard amide coupling conditions to afford the corresponding hydroxyamide (VI-1), which can be oxidized as described in Method IV to afford the ketoamide (VI-2, A-B-C-D).

VI-2 A-B-C-D

Method VII: Synthesis of hydroxyprolines (VH-5, A-B-C-D)

[0129] 4-Hydroxyproline methyl ester can be coupled with a protected amino acid using standard amide coupling procedures to provide the corresponding Boc protected hydroxyproline ester (VII- 1, B-C). The protecting group can be cleaved using standard deprotection methods (e.g. for a Boc, deprotection can be accomplished via HC1) and the resulting amino ester can be reacted with acid chloride or carboxylic acid using standard conditions to afford the hydroxyproline esters (VII-2, A-B-C). The ester is hydrolyzed using basic protocols such as LiOH or NaOH in THF/MeOH to provide the carboxylic acid (VII-3), which is then coupled with aminoheterocyclic 2-hydroxyacetamide (1-6, D) to provide the hydroxyamide (VII-4). Oxidation of the hydroxyamide as described in Method IV provides the hydroxyproline ketoamide (VII-5, A-B-C-D).

[0133] The sulfonamides (XI-1) can be prepared from the corresponding ketone using the method of Nitta, A., et al. Bioorg. Med. Chem. Lett. 2008, 18, 5435. This sulfonamide is converted to the corresponding boronate ester (XI-2) using the method of Ellman, J., et al. J. Org. Chem. 2014, 79, 3671. The sulfonamide group is deprotected using standard procedures such as HC1 to afford the amino boronate ester (XI-3). The amino boronate is coupled to a carboxylic acid (A-B-C-OH) using standard amide coupling procedures to afford the fully elaborated boronate ester (XI-4). Deprotection of the boronate ester using standard acidic methods such as HCl/isobutane boronic acid gives the corresponding boronic acid (XI-5, A-B-C-D).
