[Technical Field]
[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of the filing date of U.S. Provisional Application No. 63 / 014,448, filed April 23, 2020, the entire contents of which are incorporated herein by reference. [Background technology]
[0002] Coronaviruses, members of the Coronaviridae and Coronavirinae subfamily, are enveloped viruses containing single-stranded, positive-sense RNA genomes 26–32 kilobases in length. Coronaviruses have been identified in several vertebrate hosts, including birds, bats, pigs, rodents, camels, and humans. Humans can acquire coronavirus infections from other mammalian hosts. Human coronavirus infections are one of the leading causes of harmful upper respiratory tract disease in humans. In addition to encoding structural proteins, most of the coronavirus genome is transcribed and translated into a polyprotein that encodes proteins essential for viral replication and gene expression. Functional polypeptides are released from the polyprotein by extensive proteolytic processing, one of the key steps in the coronavirus life cycle. Without proteolysis, the virus would not package. This is primarily accomplished by the 33.1 kDa main protease (MPro), also known as the 3C-like protease (3CLPro).
[0003] The central nervous system (CNS) includes the brain and spinal cord. The CNS is vulnerable to a variety of disorders that can be caused by a variety of factors, including genetics, trauma, infection, degeneration, structural defects and / or damage, tumors, impaired blood flow, and autoimmune diseases. Symptoms of CNS disorders vary depending on the area of the nervous system involved and the cause of the disorder.
[0004] The development of effective treatments for CNS disorders has lagged behind other therapeutic areas due to the complexity of such disorders and the lack of efficient technologies for delivering therapeutic agents across the blood-brain barrier. Therefore, there is great interest in developing novel therapeutic approaches for CNS disorders. Summary of the Invention

[0088] The term "pharmaceutically acceptable salt" refers to a salt that, within the scope of sound medical judgment, is suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response, etc., and is commensurate with a reasonable benefit / risk ratio.
[0089] Pharmaceutically acceptable salts are well known in the art. For example, Berge et al. describe pharmaceutically acceptable salts in detail in "J. Pharmaceutical Sciences, 1977, 66, 1-19," which is incorporated herein by reference. Pharmaceutically acceptable salts of the compounds described herein include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable non-toxic acid addition salts are salts of amino groups formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid, or by using other methods known in the art, such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecyl sulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxyethanesulfonate. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N-type salts of 2-phenylpropionate, ... +(C 1~4 Alkyl)4 - Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, etc. Further pharmaceutically acceptable salts include non-toxic ammonium, quaternary ammonium, and amine cations formed, where appropriate, using counterions such as halides, hydroxides, carboxylates, sulfates, phosphates, nitrates, lower alkyl sulfonates, and aryl sulfonates.
[0090] The term "solvate" refers to a form of a compound that is combined with a solvent, typically by solvolysis. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, dimethyl sulfoxide (DMSO), tetrahydrofuran (THF), diethyl ether, and the like. The compounds described herein can be prepared, for example, in crystalline form, and can be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric and non-stoichiometric solvates. In certain instances, a solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid. "Solvate" encompasses both solution-phase and isolable solvates. Representative solvates include hydrates, ethanolates, and methanolates.
[0091] It should also be understood that compounds that have the same molecular formula but that differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed "isomers." Isomers that differ in the arrangement of their atoms in space are termed "stereoisomers."
[0092] Stereoisomers that are not mirror images of one another are called "diastereomers," while stereoisomers that are non-superimposable mirror images of each other are called "enantiomers." When a compound has an asymmetric center, for example, when it is bonded to four different groups, a pair of enantiomers is possible. Enantiomers can be characterized by the absolute configuration of their asymmetric center and described by the R- and S-sequencing rules of Cahn and Prelog, or by the way molecules rotate the plane of polarized light and are designated as dextrorotatory or levorotatory (i.e., as (+)- or (-)-isomers, respectively). Chiral compounds can exist as either individual enantiomers or as mixtures thereof. A mixture containing equal proportions of enantiomers is called a "racemic mixture."
[0093] The term "prodrug" refers to a compound having a cleavable group that becomes a compound described herein by solvolysis or under physiological conditions and is pharmaceutically active in vivo. Examples include, but are not limited to, choline ester derivatives, N-alkylmorpholine esters, and the like. Other derivatives of the compounds described herein are active in both their acid and acid-derivative forms, but the acid-sensitive forms often offer advantages of solubility, tissue compatibility, or delayed release in mammalian organisms (Bundgard, H., Design of Prodrugs, pp. 7-9, 21-24, Elsevier, Amsterdam 1985). Prodrugs include acid derivatives well known to those skilled in the art, such as esters prepared by reacting the parent acid with an appropriate alcohol, or amides prepared by reacting the parent acid compound with a substituted or unsubstituted amine, acid anhydride, or mixed anhydride. Simple aliphatic or aromatic esters, amides, and anhydrides derived from acidic groups pendant on the compounds described herein are specific prodrugs. In some cases, it is desirable to prepare double ester prodrugs, such as (acyloxy)alkyl esters or ((alkoxycarbonyl)oxy)alkyl esters. The compounds described herein can be used in combination with C1-C8 alkyl, C2-C8 alkenyl, C2-C8 alkynyl, aryl, C7-C 12Substituted aryl and C7-C 12 Aryl alkyl esters may be preferred.
[0094] The terms "inhibit," "inhibit," "inhibits," or "inhibitor" refer to the ability of a compound to reduce, slow, stop, or prevent the activity of a particular biological process in a cell relative to a vehicle.
[0095] When a compound, pharmaceutical composition, method, use, or kit is said to "selectively," "specifically," or "competitively" bind to a first protein, the compound binds to the first protein with a higher binding affinity (e.g., about 2-fold or more, about 5-fold or more, about 10-fold or more, about 30-fold or more, about 100-fold or more, about 1,000-fold or more, or about 10,000-fold or more) than it binds to a second protein (or a protein that is different from the first protein). When a compound is said to "selectively," "specifically," or "competitively" modulate (e.g., increase or inhibit) the activity of a protein, the compound modulates the activity of the protein to a greater extent (e.g., about 2-fold or more, about 5-fold or more, about 10-fold or more, about 30-fold or more, about 100-fold or more, about 1,000-fold or more, or about 10,000-fold) than the activity of at least one protein that is different from the first protein.
[0096] The term "abnormal activity" refers to activity that deviates from normal activity. The term "increased activity" refers to activity that is higher than normal activity.
[0097] The terms "composition" and "formulation" are used interchangeably.
[0098] A "subject," "individual," or "patient" to whom administration is contemplated refers to a human (i.e., a male or female of any age, e.g., a pediatric subject (e.g., an infant, child, or adolescent) or an adult subject (e.g., a young adult, middle-aged adult, or elderly)) or a non-human animal. A "subject" can be a human, but also includes other mammals, particularly mammals useful as laboratory models of human disease, such as mice, rats, rabbits, dogs, and the like. A "patient" refers to a human subject in need of treatment for a disease. In certain embodiments, the subject is a human with or at risk for a central nervous system (CNS) disorder, obesity, diabetes, or hyperlipidemia.
[0099] The terms "administer," "administering," or "administration" refer to implanting, absorbing, ingesting, injecting, inhaling, or otherwise introducing a compound described herein or a composition thereof into or onto a subject.
[0100] The terms "treatment," "treat," and "treating" refer to reversing, alleviating, delaying the onset, or inhibiting progression of a disease as described herein. In some embodiments, treatment may be administered after one or more signs or symptoms of a disease have appeared or been observed. In other embodiments, treatment may be administered in the absence of signs or symptoms of a disease. For example, treatment may be administered to a susceptible subject prior to the onset of symptoms (e.g., in light of a history of symptoms and / or exposure to a pathogen) to delay or prevent the onset of disease. Treatment may also be continued after symptoms have resolved, e.g., to delay or prevent recurrence.
[0101] The term "continuously" refers to uninterrupted administration for the period of time medically or therapeutically necessary, including, but not limited to, for example, infusion with or without a pump, respiratory therapy, inhalation therapy.
[0102] Alleviating the target disease / disorder includes delaying the onset or progression of the disease or reducing the severity of the disease. Alleviating the disease does not necessarily require a curative result. As used herein, "delaying" the onset of the target disease or disorder means postponing, hindering, slowing, delaying, stabilizing, and / or postponing the progression of the disease. This delay can be for various lengths of time, depending on the history of the disease and / or the individual being treated. A method of "delaying" or alleviating the onset of a disease, or a method of delaying the onset of a disease, is a method of reducing the likelihood of developing one or more symptoms of the disease within a given time frame and / or reducing the severity of symptoms within a specific time frame, compared to not using the method. Such comparisons are usually based on clinical studies using a sufficient number of subjects to produce statistically significant results.
[0103] "Onset" or "progression" of a disease refers to the initial symptoms and / or subsequent progression of the disease. Disease onset can be detected and assessed using standard clinical techniques well known in the art. However, onset also refers to progression, which may be undetectable. For purposes of this disclosure, onset or progression refers to the biological course of symptoms. "Onset" includes onset, recurrence, and onset. As used herein, "onset" or "onset" of a target disease or disorder includes initial onset and / or recurrence.

[0159] (III) Application of the composition of formula (I) The present disclosure provides pharmaceutical compositions and methods for treating and / or alleviating symptoms of certain disorders, diseases affecting a subject.
[0160] Viruses are small infectious agents that replicate only within the living cells of a host organism. Viruses can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. While not within an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or virions, consisting of (i) genetic material, i.e., long molecules of DNA or RNA that code for the structure of the proteins on which the virus acts; (ii) a protein coat, or capsid, that surrounds and protects the genetic material; and, in some cases, (iii) a lipid outer envelope.
[0161] Antivirals are a class of drugs designed to treat viral infections. Because the human body can deal with the majority of viruses through its immune system, these drugs target certain specific toxicities and life-threatening diseases that the body cannot fight alone or struggles to counter. Researchers working on "rational drug design" strategies to develop antiviral drugs have attempted to attack viruses at any stage of their life cycle (e.g., before cell entry, entry inhibition, and uncoating inhibition) during the viral synthesis, assembly, and release phases.
[0162] Members of the Coronaviridae family include virus strains with different phylogenetic origins (www.thelancet.com, published online January 29, 2020, https: / / doi.org / 10.1016 / S0140-6736(20)30251-8), which cause varying degrees of mortality and morbidity. Therefore, treatment of coronavirus infections varies depending on the specific strain causing the infection. Currently, there are no approved antiviral drug treatments for any coronavirus. Given the conservation of key residues and their functional importance, 3CLPro is expected to be an important target for the design of ubiquitous anticoronavirus drugs for infectious diseases.
[0163] In some embodiments, the present disclosure provides compositions capable of effectively inhibiting 3C-like protease (3CLPro), and uses thereof in inhibiting 3CLPro, treating patients suffering from a viral infection, reducing viral load in its clinical outcome, and / or reducing morbidity or mortality. The methods include administering to a subject in need thereof an effective amount of a composition comprising: (1) one or more compounds of Formula (I) or pharmaceutically acceptable salts thereof; and (2) a pharmaceutically acceptable carrier; wherein in some embodiments, the effective amount is a prophylactically effective amount (e.g., an amount effective to inhibit viral 3CLPro in a subject in need thereof, or an amount effective to treat a subject suffering from a viral infection, reducing viral load in its clinical outcome, and / or reducing morbidity or mortality).
[0164] In some embodiments, the target viral infection treated by the methods disclosed herein is pneumonia caused by infection with the coronavirus genus, which may include novel coronavirus (2019-nCoV), severe acute respiratory syndrome coronavirus (SARS-CoV), and Middle East respiratory syndrome coronavirus (MERS-CoV). In some embodiments, the target viral infection treated by the methods disclosed herein is caused by alphacoronavirus strains 229E and NL63, betacoronavirus strains OC43 and HKU1, and coronavirus strains caused by novel transmission from other mammals to humans that share protein homology and proteolytic function of 3CLPro.
[0165] In yet another aspect, the disclosure further provides a method for reducing an individual's risk of developing a pathological coronavirus infection with clinical sequelae, the method generally involving administering a therapeutically effective amount of a composition comprising a 3CLPro) inhibitor and a therapeutically effective amount of a composition herein.
[0166] Any of the compounds described herein (e.g., compounds of Formula (I)) can be used to treat diseases or disorders. In certain embodiments, provided herein are methods for improving basic behavioral function, weight loss, hyperactivity, anxiety, depression, suicidal thoughts and / or behaviors, sensorimotor gating, pain threshold, memory, and / or cognitive function in a subject in need of treatment. Such compounds can also be used to treat diseases or disorders associated with DAAO, such as central nervous system disorders (e.g., those described herein). The compounds can also be used to treat obesity disorders.
[0167] As used herein, the term "treating" refers to the application or administration of a composition comprising one or more active agents to a subject in need of treatment, e.g., a subject with a target disease or disorder, a symptom of a disease / disorder, or a predisposition to a disease / disorder, with the intent to cure, relieve, alleviate, relieve, alter, relieve, improve, ameliorate, or affect the disorder, symptom of a disease, or predisposition to a disease or disorder.
[0168] Alleviating the target disease / disorder includes delaying the onset or progression of the disease or reducing the severity of the disease. Alleviating the disease does not necessarily require a curative result. As used herein, "delaying" the onset of the target disease or disorder means postponing, hindering, slowing, delaying, stabilizing, and / or postponing the progression of the disease. This delay can be for various lengths of time, depending on the history of the disease and / or the individual being treated. A method of "delaying" or alleviating the onset of a disease, or a method of delaying the onset of a disease, is a method of reducing the likelihood of developing one or more symptoms of the disease within a given time frame and / or reducing the severity of symptoms within a specific time frame, compared to not using the method. Such comparisons are usually based on clinical studies using a sufficient number of subjects to produce statistically significant results.
[0169] "Onset" or "progression" of a disease refers to the initial symptoms and / or subsequent progression of the disease. Disease onset can be detected and assessed using standard clinical techniques well known in the art. However, onset also refers to progression, which may be undetectable. For purposes of this disclosure, onset or progression refers to the biological course of symptoms. "Onset" includes onset, recurrence, and onset. As used herein, "onset" or "onset" of a target disease or disorder includes initial onset and / or recurrence.
[0170] To achieve any of the intended therapeutic effects described herein, an effective amount of a compound described herein (e.g., a compound of Formula (I)) can be administered to a subject in need of treatment via an appropriate route.
[0171] The terms "subject," "individual," and "patient" are used interchangeably herein and refer to a mammal being evaluated for therapy and / or treated. The subject can be a human, but also includes other mammals, particularly mammals useful as laboratory models of human disease, such as mice, rats, rabbits, dogs, and the like.
[0172] A human subject in need of treatment may be a human patient who has, is at risk for, or is suspected of having a target disease / disorder, such as a CNS disorder, or an obesity-related disease, such as diabetes, hyperglycemia, hypercholesterolemia, or hyperlipidemia. A subject with a target disease or disorder can be identified by routine medical examination, such as clinical tests, organ function tests, and / or behavioral tests. A subject suspected of having any of such target diseases / disorders may exhibit one or more symptoms of the disease / disorder. A subject at risk for a disease / disorder may be a subject with one or more risk factors for the disease / disorder, such as genetic factors. In some cases, the human subject is a child who has, is suspected of having, or is at risk for childhood-related obesity or CNS disorders, such as attention-deficit / hyperactivity disorder (ADHD), autism, Asperger's syndrome, obsessive-compulsive disorder, depression, suicidal thoughts and / or behaviors, psychosis, chronic pain, and learning disabilities.
[0173] The methods and compositions described herein can be used to treat CNS disorders. Exemplary CNS disorders that can be treated by the methods and compositions described herein include schizophrenia, psychotic disorders, Alzheimer's disease, frontotemporal dementia, vascular dementia, dementia with Lewy bodies, senile dementia, mild cognitive impairment, benign amnesia, closed head injury, autism spectrum disorder, Asperger's syndrome, fragile X syndrome, attention deficit hyperactivity disorder, attention deficit disorder, obsessive-compulsive disorder, tic disorders, childhood learning disabilities, premenstrual syndrome, depression, major depressive disorder, anhedonia, and suicidal thoughts and / or behaviors. , bipolar disorder, anxiety disorder, panic disorder, post-traumatic stress disorder, chronic mild and unpredictable stress, eating disorders, addictive disorders, personality disorders, Parkinson's disorder, Huntington's disorder, multiple sclerosis, amyotrophic lateral sclerosis, ataxia, Friedreich's ataxia, Tourette's syndrome, nocturnal enuresis, non-epileptic seizures, blepharospasm, Duchenne muscular dystrophy, stroke, chronic pain, neuropathic pain including hyperalgesia and allodynia, diabetic polyneuropathy, and chronic pain syndromes.
[0174] Obesity-related diseases include diseases and disorders that lead to obesity and diseases and disorders that occur more frequently in obese patients.Obesity is a medical condition characterized by the accumulation of excess body fat to a degree that can adversely affect health.Obesity can be determined by body mass index (BMI), which is a measurement obtained by dividing a person's weight by the square of their height.For example, if a BMI is 30 kg / m 2 Exemplary diseases associated with obesity include, but are not limited to, eating disorders, anorexia nervosa, bulimia nervosa, stroke, coronary heart disease, heart attack, congestive heart failure, congenital heart disease, hypertension, diabetes mellitus, hyperlipidemia, hypercholesterolemia, nonalcoholic steatohepatitis, insulin resistance, hyperuricemia, hypothyroidism, osteoarthritis, gallstones, infertility (e.g., hypogonadism and hyperandrogenism), obesity hypoventilation syndrome, obstructive sleep apnea, chronic obstructive pulmonary disease, and asthma.
[0175] In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) four times a day to once every three months, inclusive. In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) four times a day, three times a day, twice a day, once a day, once every day, once every three days, once every week, once every other week, once a month, once every other month, or once every three months. In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) once a day, twice a day, three times a day, four times a day, five times a day, six times a day, seven times a day, eight times a day, nine times a day, or ten times a day. In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) four times a day. In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) once every three months. In some embodiments, a human subject is administered a compound described herein (e.g., a compound of Formula (I)) once every month, once every two months, once every three months, once every four months, once every five months, or once every six months. In some embodiments, a human subject is treated concurrently with, prior to, or subsequent to one or more additional pharmaceutical agents for treating and / or reducing the risk of a CNS disorder or obesity-related disease.
[0176] As used herein, "effective amount" refers to the amount of each active agent (e.g., a compound of Formula (I) described herein) required to confer a therapeutic effect on a subject, alone or in combination with one or more other active agents, such as one or more of the second therapeutic agents described herein. In some embodiments, the therapeutic effect is inhibiting DAAO activity in a subject (e.g., by at least 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or more). In some embodiments, the therapeutic effect is improving baseline behavioral function, weight loss, hyperactivity, anxiety, depression, suicidal thoughts and / or behaviors, sensorimotor gating, pain threshold, memory, and / or cognitive function. In some embodiments, the therapeutic effect is alleviating one or more symptoms associated with any of the CNS disorders described herein. Alternatively, or in addition, the therapeutic effect is maintaining or reducing the subject's weight.
[0177] The N-methyl-D-aspartate (NMDA) receptor is a subtype of glutamatergic receptor that plays an important role in cognition, memory, and neurotoxicity. Modulation of NMDA receptors has been suggested to be beneficial for the treatment of central nervous system disorders. D-amino acid oxidase (DAAO) is a peroxisomal enzyme that oxidizes D-amino acids to their corresponding imino acids. DAAO has been reported to be involved in the metabolism of D-amino acids, including D-serine, in the brain and in the regulation of glutamatergic neurotransmission. Therefore, DAAO is a target for treating central nervous system (CNS) disorders related to D-serine and / or glutamatergic neurotransmission. Furthermore, DAAO degrades D-serine to 3-hydroxypyruvate, a potential mediator of type 2 diabetes (Zhang, 2015). This suggests that DAAO inhibitors could be used to treat obesity, diabetes, and hyperlipidemia.
[0178] It will be clear to those skilled in the art how to determine whether the amount of the composition described herein achieves a therapeutic effect. As will be recognized by those skilled in the art, the effective amount will vary depending on individual patient parameters, including the specific condition being treated, the severity of the condition, age, physical condition, size, sex, and weight, the duration of treatment, the nature of concomitant therapy (if any), the specific route of administration, genetic factors, and similar factors within the knowledge and expertise of medical professionals. These factors are well known to those skilled in the art and can be addressed with only routine experimentation. In general, it is preferable to use the maximum dose of each component or combination thereof, i.e., the highest safe dose according to sound medical judgment.
[0179] Empirical considerations such as half-life generally contribute to the determination of dosage. The frequency and / or route of administration can be determined and adjusted over the course of treatment, and is generally, but not necessarily, based on the treatment and / or suppression and / or improvement and / or delay of the target disease / disorder. Alternatively, a continuous sustained-release formulation of the composition described herein may be appropriate. Various formulations and devices for achieving sustained release are known in the art.
[0180] In general, for administration of any composition, an exemplary daily dosage can range from about 0.1 μg / kg to 3 μg / kg to 30 μg / kg to 300 μg / kg to 3 mg / kg, to 30 mg / kg to 100 mg / kg, or to 300 mg / kg to 1 gram / kg or more, depending on the factors mentioned above. For repeated administration over several days or more, depending on the condition, treatment is sustained until a desired suppression of symptoms occurs or until a therapeutic level sufficient to alleviate the target disease or disorder or its symptoms is achieved. An exemplary dosing regimen involves administering one or more initial doses at appropriate intervals over an appropriate period of time. If desired, multiple maintenance doses can be administered to the subject at appropriate intervals over a suitable period of time. However, other dosing regimens may be useful depending on the pharmacokinetic decay pattern the physician desires to achieve. For example, administration from 1 to 24 times daily or weekly is contemplated. In some embodiments, a dosing range of about 3 μg / mg to about 2 mg / kg (e.g., about 3 μg / mg, about 10 μg / mg, about 30 μg / mg, about 100 μg / mg, about 300 μg / mg, about 1 mg / kg, about 3 mg / kg, about 30 mg / kg, and about 300 mg / kg) can be used. In some embodiments, the dosing frequency can be given hourly, every 2 hours, 4 times a day, 3 times a day, twice a day, once a day, once every other day, once weekly, once every other week, once every 4 weeks, once every 2 months, once every 3 months, or only once continuously for as long as medically or therapeutically needed. Dosing regimens can vary over time.
[0181] In some embodiments, a normal weight adult patient can be administered a dose ranging from about 0.3 to 500.00 mg / kg / day (e.g., 0.5 to 400 mg / kg / day, 1 to 300 mg / kg / day, 5 to 300 mg / kg / day, or 10 to 200 mg / kg / day). The particular dosing regimen, i.e., dose, timing, and repetition, will vary depending on the particular individual and their medical history, as well as the characteristics of the individual drug (such as the drug's half-life and other considerations known in the art).
[0182] The composition (e.g., a pharmaceutical composition, a health food composition, a dietary supplement composition, or a medical food composition) can be administered to a subject using conventional methods known to those skilled in the medical field, depending on the type of viral infection or the site of the disease being treated.
