SPECIFICATION

This application claims benefit of U.S. Provisional Patent Application No. 62/344,591, filed June 2, 2016, which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

The emergence of the Zika virus represents a global health threat (Sikka, V. et al. "The emergence of Zika Virus as a Global Health Security Threat: A Review and Consensus Statement of the INDUSEM Joint Working Groups (JWG). Journal of Global Infectious Diseases. 8 (2016): 3-15). The present invention represents a method for prevention and treatment of the Zika virus. It provides physical, chemical, and metabolic barriers to infection by this pathogenic agent.

The Zika virus is a member of the family Flaviviridae and is an RNA containing virus. It is usually transmitted by an Aedes mosquito which injects it into the skin with a stinger, causing infection of three types of skin cells (epidermal keratinocytes, dermal fibroblasts, dermal macrophages)(Hamel, R., et al., "Biology of Zika Virus Infection in Human Skin Cells" J. Virol. 89 (2015) :8880-8896.) and then proceeds to a viremia. It can also be transmitted sexually. It is asymptomatic in 80% of people infected, but causes mild to moderate systemic symptoms such as arthralgia, myalgia, and rash in 20% of people. Additionally it has caused catastrophic nervous system developmental impairment and microcephaly in fetuses and newborns, and Guillain-Barre paralytic syndrome in some adults. There is at this time no preventative vaccine or direct antiviral treatment. There is no way to reverse the catastrophic developmental impairment in embryos, fetuses, and newborns. For Guillain Barre Syndrome, only supportive care and immunoglobulin treatment, which is only partially effective, are available.

The inventor has found that mycophenolic acid, derivatives thereof, and combinations with other agents, such as minocycline, doxycycline, tetracycline, tetracycline derivatives, L- DOPA, and dopamine are effective in preventing and/or treating certain viruses. In addition, the inventor has found that minocycline, doxycycline, tetracycline, tetracycline derivatives, L- DOPA, dopamine, and combinations thereof are useful for preventing and/or treating a pathogenic infection in a patient, including, for example, viral infection, bacterial infection, fungal infection, parasitic infection, and combinations thereof.

The invention provides means for prevention and/or treatment of dangerous pathogenic organisms. The invention provides methods and pharmaceutical compositions which are active against an unusually wide range of pathogens and which have lesser toxicity compared to many currently available antimicrobial therapies. All references cited herein are incorporated herein by reference in their entireties.

BRIEF SUMMARY OF THE INVENTION

The method is comprised of two parts. These two parts can be administered together or sequentially.

Part A-Methods for depletion of guanosine-containing nucleosides and nucleotides.

Part B-Methods for administering melanin and/or increasing the body content of melanin by modulation of metabolic processes.

The parts are briefly summarized below.

Part A - Method for depletion of guanosine-containing nucleosides and nucleotides.

Guanine is a purine base which is a component of nucleosides such as guanosine and nucleotides such as guanosine monophosphate, guanosine diphosphate, and guanosine triphosphate, cyclic guanosine monophosphate, etc. Guanine is required for replication of most DNA and RNA. It is also a component of the ubiquitous G protein receptors, which are involved in innumerable signaling pathways.

Most microorganisms that cause disease do so partially by replicating themselves in high numbers. This includes viruses, bacteria, fungi, and parasites. This requires replication of DNA in bacteria, fungi, and parasites, and replication of DNA or RNA in viruses. In Zika, it is the RNA which replicates.

It has been demonstrated that restriction or complete inhibition of guanine supplies prevents replication of some viruses and other pathogenic organisms such as bacteria. This can be accomplished by several chemical agents (e.g. mycophenolic acid, tiazofurin, selenazofurin, ribavirin, 5 - ethinyl - 1 - β - D - ribofuranosylimidazole-4-carboxamide))(Neyts, J., and De Clercq, E. "Mycophenolate Mofetil Strongly Potentiates the Anti-herpesvirus Activity of Acyclovir." Antiviral research 40 (1998): 53-56.). Restriction of guanine supplies is generally not used in medical treatment of any infectious disease. It should be noted that early studies of mycophenolate showed relatively rapid emergence of bacterial resistance, and perhaps this is the reason why this strategy has not been adopted. Additionally, it is possible to significantly deplete a human's supply of guanosine by a novel selective diet restriction which is described below. Part B -Methods for administering melanin and/or increasing the body content of melanin by modulation of metabolic processes. Melanin is a pigment best known for its ability in human skin to absorb ultraviolet radiation from the sun. Melanin has been clearly demonstrated to have antimicrobial properties which are active against some viruses, bacteria, fungi and parasites. Its mechanism of action seems to be unknown. The best studied melanin in the literature is derived from cuttlefish ink. Cuttlefish is a type of cephalopod. Octopus and squid are also cephalopods and also have inks, which are used as a defense mechanism against predators. The ink contains approximately 15 to 20% melanin, about 5% protein and carbohydrates, and the rest is water.

Human beings also continuously synthesize melanin in the skin and perhaps in the nervous system. Various hormones and other agents have been demonstrated to be capable of increasing melanin synthesis in humans and other mammals. One example is Melanocyte- Stimulating Hormone (MSH).

The present invention represents a fundamentally novel strategy in developing therapy against Zika virus, other microbes and parasites. Historically, and increasingly so in the recent years, researchers, pharmaceutical companies, and governments devote their efforts toward targeting single agents or small groups of specific microbes. For instance, an enormous amount of resources has appropriately been devoted to fighting the HIV virus. However, as a result, most of the therapies developed are only active against that single microbe. Similarly, many of the new antibiotics developed in the last few decades are targeted to a small group of microbes. For instance the cephalosporins were developed specifically against penicillin resistant bacteria. While of course these advances are welcome, the cephalosporins are generally only active against the rather limited organisms against which they were developed.

The present invention represents a fundamentally different strategy from the historical strategy just described. The present invention targets the Zika virus and other disease-causing microbes including viruses, bacteria, fungi, and parasites. It does this using agents and methods with little toxicity compared to existing therapies.

DETAILED DESCRIPTION OF THE INVENTION

To the extent that the term "include," "have," or the like is used in the description or the claims, such term is intended to be inclusive in a manner similar to the term "comprise" as "comprise" is interpreted when employed as a transitional word in a claim.

The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments.

In order to provide a clear and consistent understanding of the specification and claims, including the scope given to such terms, the following definitions are provided:

Administration: The application or delivery of a drug to a mammal in need of the drug. This term is intended to include any means of administration which accomplishes the application or delivery of the drug (i. e., topical, oral, aerosol, suppository, parenteral, e. g., intravenous, intramuscular, subcutaneous injection, e. g., into the tissue, intraperitoneally and the like). The term is also intended to include any means necessary to accomplish such administration. The term is further intended to include the in vivo production of a drug or aggregation of a drug moderated by another substance such as an enzyme (tyrosinase) or enzyme gene (tyrosinase gene) to moderate production of a drug (melanin) or its precursors, or a concentrating hormone (MCH) subcutaneously to moderate drug (melanin) concentration.

Treatment: Treatment is defined as administration to a mammal suffering from infections or burns or administration to a mammal at risk for such infections. Melanin: Melanins are polymers produced by polymerization of reactive intermediates. The polymerization mechanisms include but are not limited to autoxidation, enzyme catalyzed polymerization and free radial initiated polymerization. The reactive intermediates are produced chemically or enzymatically from precursors. Suitable enzymes include, but are not limited to peroxidases and catalases, polyphenol oxidases, tyrosinases, tyrosine hydroxylases or lactases. The precursors which are connected to the reactive intermediates are hydroxylated aromatic compounds. Suitable hydroxylated aromatic compounds include, but are not limited to 1) phenols, polyphenols, aminophenols and thiophenols of aromatic or polycyclicaromatic hydrocarbons, including but not limited to phenol, tyrosine, pyrogallol, 3-aminotyrosine, thiophenol and. alpha, -naphthol; 2) phenols, polyphenols, aminophenols, and thiophenols of aromatic heterocyclic or heteropolycyclic hydrocarbons such as but not limited to 2- hydroxypyrrole, 2-pyrazole, 4- hydroxypyridine, 8-hydroxyquinoline, and 4, 5- dihydroxybenzothiazole. The term melanin includes naturally occurring melanins which are usually high molecular weight polymers and low molecular weight polymers as well as melanin analogs as defined below. Naturally occurring melanin includes eumelanins, phaeomelanins, neuromelanins and allomelanins. The term melanin is also intended to include trichochromes when used hereafter. The term "melanin"is further intended to include melanin, melanin precursors, melanin analogs, melanin variants and melanin derivatives unless the context dictates otherwise.

Melanin Analog: Melanin in which a structural feature that occurs in naturally occurring or enzymatically produced melanins is replaced by an unusual substituent divergent from substituents traditionally present in melanin. An example of an unusual substituent is selinium in place of sulfur, such as selinocysteine.

Melanin Derivative: This term is intended to include any derivative of melanin which is capable of being converted to either melanin or a substance having melanin activity. An example of a melanin derivative is melanin attached to a dihydrotrigonelline carrier such as described in Bodor, N. , Ann. N. Y. Acad. Sci. 507,289 (1987) to enable the melanin to cross the blood-brain barrier. The term melanin derivatives is also intended to include chemical derivatives of melanin, such as an esterified melanin.

Melanin Variant: Melanin variants include various subsets of melanin substances that occur as families of related materials. Included in these subsets, but not limited thereto, are: (1) Naturally occurring melanins produced by whole cells that vary in their chemical and physical characteristics; (2) Enzymatically produced melanins prepared from a variety of precursor substrates under diverse reaction conditions; (3) Melanin analogs in which a structural feature that occurs in (1) or (2) above is replaced by an unusual substituent divergent from the traditional; and (4) Melanin derivatives in which a substituent in a melanin produced in (1), (2) or (3) above is further altered by chemical or enzymatic means.

Tyrosinase: An enzyme which, in mammals, catalyzes : (a) the hydroxylation of tyrosine to dopa (3,4-dihydroxyphenylalanine) ; (b) the oxidation of dopa to dopaquinone; and (c) may catalyze the oxidation of 5,6-dihydroxyindole to indole-5,6- quinone. All of these reactions catalyzed by tyrosinase take place in the biosynthetic pathway which produces melanin. Tyrosinase is most commonly found in a glycosylated form in vivo.

Melanin Concentrating Hormone: Melanin concentrating hormone (MCH) is a peptide which has been isolated from fish pituitary glands, characterized and synthesized (Kawauchi, H. et al. , Nature 305,321 (1983) ). MCH has also been localized by immunohistochemistry in the brain and pituitary gland of salmon, frogs and rats (Baker, B.J. et al. , Gen. Comp. Endocrinol. 50,1423 (1983), Naito, N. et al. , Neurosci. Lett. 70,81 (1986), Skotfitsch, G. et al. , Proc. Natl. Acad. Sci. USA 83,1528 (1986) and Zamir, N. et al. , Brain Research 373,240 (1986) ).

A mammalian MCH-like substance has been detected using salmon MCH antiserum directed against salmon MCH by radioimmunoassay and immunohistochemistry (Zamir, N. et al. , Proc. Natl. Acad. Sci. USA, supra). This mammalian MCH exhibits distinct chromatographic properties on both Reversed Phase High Performance Liquid Chromatography (RP-HPLC) and gel chromatography when compared to the fish enzyme. Id. The persistence of this mammalian MCH in the mammalian hypothalamo- neurohypophyseal system suggests a role for MCH in posterior pituitary function, such as the regulation of food and water intake. Id.

Other functions of this mammalian MCH peptide have also been suggested.

For example, due to the identification of MCH fibers in the human median eminence and pituitary stalk, it has been suggested that the peptide causes the aggregation or concentration of melanin in cells of the central nervous system and may be involved in the regulation of anterior pituitary function (Pelletier, G. et al. , Brain Research 423,247 (1987) ). Furthermore, Sekiya, K. et al. (Neuroscience 25,925, 1988) suggest that MCH may act as a neurotransmitter and/or neuromodulator in the central nervous system or may regulate the pituitary portal-blood system and/or the neurosecretory system in mammals.

Melanin: Naturally occurring melanins include eumelanins, phaeomelanins, neuromelanins and allomelanins. Trichochromes which are low molecular weight polymers derived from the oxidation of tyrosine are also considered melanins for the purpose of this invention.

Melanins and melanin variants are as defined above. Melanin variants are considered melanins for the purpose of this invention unless the context indicates otherwise.

The patient or subject to be treated may be any animal or human. The subject is preferably mammalian. In some embodiments the subject is a human. In other embodiments the subject is an animal, more preferably a non-human mammal.

Part A - Methods for depletion of guanosine-containing nucleosides and nucleotides; Specialized Diets and Dietary Program for Treatment of Zika and other Viral Diseases

Part A can be implemented using either or both of the following approaches.

Part Al - Administering agents which depletes guanosine-containing nucleosides and nucleotides.

One approach is that of administering agents (e.g. chemicals, or molecules such as immunoglobulins) that have the effect of reducing the content of guanosine-containing nucleosides and nucleotides in particular tissues or the whole body. One way to do this, for example, is that used by mycophenolate and similar compounds that inhibit the EVIPDH enzyme, which is necessary for the production of guanosine monophosphate, a key intermediate in the nucleotide synthesis pathway. Another approach would be to administer agents which bind to guanine, or guanosine-containing nucleosides and nucleotides, to reduce their availability.

Part A2 - Dietary restriction of guanosine intake and substances used by the body to synthesize guanosine. We describe below specialized diets that we have constructed and used which specifically reduce the dietary intake of guanosine.

It utilizes diets which are low in nucleic acids and their components but which are not nucleotide-free. The diets contain approximately 3% to 50% of the amount by weight of nucleotides seen in the normal western diet (2000 mg/day, from Ekelman, K. Disodium 5'Guanylate and Disodium 5'-Inosate. WHO Food Additives Series, No. 32 (1993), and preferably 10%-40%. The percentage of nucleotides, nucleosides, and other nucleic acid components in specific foods has been published by different researchers using various analytic techniques over the years (e.g. Lassek, E, and A Montag. "Nucleic Acid Components in Carbohydrate-rich Food." Zeitschrift fur Lebensmittel-Untersuchung und -Forschung 190, no. 1 (1990): doi: 1689090; Souci, S W, W Fachmann, H Kraut, Eva Kirchhoff, and Forschungsanstalt Forschungsanstalt fur Deutsche. Food Composition and Nutrition Tables. Stuttgart: Medpharm, 2008; Brule, D, G Sarwar, and L Savoiet. "Purine Content of Selected Canadian Food Products." Journal of Food Composition and Analysis 1, no. 2 (1988): 130-138.). A survey of the world literature on nucleic acid content of foods was conducted. In some cases where the individual nucleotides were not reported, the amount of total nucleotides and of guanosine-containing nucleotides could be estimated from the reported purine content. A set of diets with different percentages of nucleotides (compared to the typical Western diet) was created. These range between about 10% to 40% of the typical Western diet. A registered dietitian created these diets which were low in nucleotides but balanced for other necessary nutrients.

Choosing a diet with a given percent (or range) of nucleotides is optimized by medical evaluation of the condition and needs of the individual patient. Medical evaluation may include the following: level of antibody titers such as those of anti-nuclear antibody, anti-dsDNA antibodies, anti-guanosine antibody, evaluation of the presence and degree of organ damage in kidneys, lungs, joints, brain, and skin, subjective symptomatology such as pain, headaches, and evaluation criteria.

Additionally, it is proposed that all patients with pathogenic infections, and individuals susceptible to developing pathogenic infections, will benefit from diets in which the nucleotide level is 45% or less than the typical western diet, and in which the guanosine and guanosine- containing nucleotides are less than 45% of the typical western diet.

2. The diets initially recommended by the physician to the patient are low in their content of guanine, a nitrogenous base, and/or guanosine, a nucleoside, compared to the usual Western diet. The patient's response to the diet is evaluated over time and diets with sequentially more nucleotide content and more palatability are recommended so that the compliance and tolerability and palatability is at such a level that the patient can for years be maintained on a reduced nucleotide diet. For instance, if the patient is started by the physician on a Step 1 diet, it is likely that after a period of weeks or months the patient will be advanced to a Step 2 diet which has a greater nucleotide content, reflected in a larger range of foods which can be taken, and is therefore more palatable. (Nucleotide-free diets are described in: Rudolph, F B, A D Kulkarni, W C Fanslow, R P Pizzini, S Kumar, and C T Van Buren. "Role of RNA As a Dietary Source of Pyrimidines and Purines in Immune Function." Nutrition 6, no. 1 (1990): 45-52; Kulkarni, A D, F B Rudolph, and C T Van Buren. "The Role of Dietary Sources of Nucleotides in Immune Function: A Review." The Journal of nutrition 124, no. 8 Suppl (1994): 1442S-1446S.: 45-52).

The inventor's reduced nucleotide diets are fundamentally different from nucleotide-free diets. The nucleotide-free diets used in published animal experiments were almost entirely devoid of nucleotides and were said to contain a level of only 0.001% (Rudolph, F B, A D Kulkarni, W C Fanslow, R P Pizzini, S Kumar, and C T Van Buren. "Role of RNA As a Dietary Source of Pyrimidines and Purines in Immune Function." Nutrition 6, no. 1 (1990): 45-52).

The inventor has conducted extensive analysis of the nucleotide content of human foods from a variety of sources, and evaluated the nutritional content and palatability of potential nucleotide-free diets. The inventor has concluded that it is not practical for most people to stay on a nucleotide-free diet in a compliant manner for the period of months required to obtain substantial clinical benefit from this approach. A nucleotide-free diet is unlikely to be sufficiently palatable for extended use and would deter compliance. Also, use of a nucleotide- free diet for months in humans would likely lead to other dietary deficiencies.

As set forth above, the invention provides treatment of a patient with a diet which contains approximately 3% to 50% of the amount by weight of nucleotides seen in the normal western diet, which contains about 2000 mg/day of nucleotides. In exemplary embodiments, the diet of the invention contains a nucleotide content of about 1000 mg/day, of about 750 mg/day, of about 500 mg/day, of about 250 mg/day, of about 100 mg/day, of about 75 mg/day, of about 50 mg/day, of about 25 mg/day. In exemplary embodiments, the diet of the invention contains a nucleotide content compared to the normal Western diet of about 50%, of about 40%, of about 30%, of about 20%, of about 10%, of about 5%, of about 3%. In exemplary embodiments, the diet of the invention contains a nucleotide content compared to the normal Western diet of 3- 50%, of about 10-40%, of about 20-30%, of about 3-40%, of about 3-30%, of about 10-30%, of about 10-20%.

2. Example diets: The nucleotide content of one Example Diet is about 28+5% of the typical Western diet. The nucleotide content of another Example Diet is about 43+5% of the typical Western diet. 3. The diet program is comprised of a period of months, e.g. 6 months, during which a physician and a dietician evaluate and work to optimize diet treatment for each pathogenic infection patient.

a. The physician initially evaluates the severity of the patient's disease based on signs and symptoms, laboratory tests, evidence of organ damage, etc., and then recommends a specific diet. The patient is followed over the next few months with repeat followup disease evaluations and diet adjustments by the physician. The patient may be asked to keep, as individually necessary, logs of symptoms such as headaches, skin rashes, joint pains, etc. These logs are periodically reviewed by the physician.

b. The dietician has an initial meeting with the patient in which the practical aspects of the diet program are explained in detail. This first visit includes describing weighing the foods to be included in the diet, characterizing the portion size for each type of food, keeping a food log, advising on the effect of cooking on food nucleotide content, etc. The patient will have one or more followup visits, as well as occasional other phone, email or other communications with the patient to answer questions and direct the treatment.

c. Depending on the severity of the patient's disease, an initial diet will be selected. As the patient stabilizes clinically or based on laboratory testing, the patient will be moved through a series of diets with increasing nucleotide content but which are still substantially lower compared to the typical Western diet. It is believed that for each patient there is a threshold for reactivity, and that if the diets are below that threshold the patient will have successfully minimized signs, symptoms, and progression of the pathogenic infection. The goal of the program is then to put the patient on a convenient and palatable maintenance diet which they can pragmatically follow for a period of years.

d. A specialized version of the low-guanosine diet has been constructed which meets the needs of pregnant women.

Part B - Methods for administering melanin, and/or increasing the body content of melanin by modulation of metabolic processes.

Melanin from different sources and in different formulations has been shown to have some therapeutic activity against some viruses, bacteria, fungi and parasites, but is not used clinically at all as far as the inventor has been able to determine. Additionally, melanin is very hard (Majerus, M. E. N., Melanism, New York: Oxford University Press, 1998) and has been shown to represent a physical barrier to pathogens both on the skin (Tang, Huaping. Regulation and function of the melanization reaction in Drosophila .Fly 3 (2009): 105-111) and internally. It is amenable to a wide range of administration methods including topical and parenteral. It is generally considered to be non-toxic itself except to pathogens. Melanin has also been produced from genetically modified organisms including fungi and bacteria.

The present invention involves the use of one or more methods from each of Part A and part B. A method from Part A and a method from Part B can be administered together (e.g. in a single formulation, or singly at the same time), or sequentially in any order (e.g. A method from part A followed by a method from part B, or a method from part B followed by a method from part A)

Guanosine - depleting chemicals such as mycophenolate are active against microbes in much lesser doses than those currently used for its main indication that of immunosuppression for transplantation.

The present invention has the further advantage that it is unlikely that the Zika virus or other organisms will be able to develop a resistance to both of the different types of attack represented by Part A and Part B together. Another advantage of the present invention is that any microbes which were to develop resistance would still be susceptible to other available therapies.

Mycophenolate

As used herein, "mycophenolates" refers herein to mycophenolic acid ("MP A") and its analogs, and their pharmaceutically acceptable salts, derivatives, prodrugs, and metabolites. Exemplary mycophenolates for use in the present invention include mycophenolic acid and mycophenylate mofetil. Mycophenolic acid, or 6-(4-hydroxy-6-methoxy-7-methyl-3-oxo-l,3- dihydroisobenzofuran-5-yl)-4- methyl-hex-4-enoic acid, has the structure

Mycophenolate mofetil is the 2-morpholinoethyl ester of mycophenolic acid, and has the formula:

Analogs of mycophenolic acid that have high IMPDH-inhibiting activity are also useful in the practice of the present invention include compounds with varying substituents in the 2-, 4-, 5-, and 6-positions on the mycophenolate core structure, as well as pharmaceutically acceptable salts, derivatives, prodrugs, and metabolites of such mycophenolate analogs. Such compounds are described for example, in the following U.S. patents incorporated herein by reference: 5,688,529 Mycophenolate mofetil high dose oral suspensions; 5,633,279 5-Substituted derivatives of mycophenolic acid 5,554,612 4-Amino-6-substituted mycophenolic acid and derivatives 5,538,969 4-Amino derivatives of 5-substituted mycophenolic acid 5,536,747 6-Substituted mycophenolic acid and derivatives 5,493,030 5-Substituted derivatives of mycophenolic acid; 5,444,072 6-Substituted mycophenolic acid and derivatives 5,441,953 4-Amino derivatives of mycophenolic acid 5,380,879 Derivatives of mycophenolic acid 4,861,776 Heterocyclic aminoalkyl esters of mycophenolic acid and derivatives thereof; 4,753,935 Morpholinoethylesters of mycophenolic acid; 4,748,173 Heterocyclic aminoalkyl esters of mycophenolic acid and derivatives thereof; 4,727,069 Heterocyclic aminoalkyl esters of mycophenolic acid, derivatives thereof

Dose and administration time of mycophenolic acid for antiviral effects are surprisingly different than the current dose and administration time for prevention of transplant rejection. It is important to understand that mycophenolic acid's anti-viral effect is likely to require a small fraction

(about 1-2% or less) of the clinical dose which is approved and commonly used for prevention of transplant rejection. For instance, Chan et al., 2013, p. 612 indicated that for a virus in which mycophenolic acid demonstrated an EC50 of 0.17 mcg/ml, the usual clinical doses of mycophenolic acid would result in local concentrations 60-300x greater than needed. This is directly comparable for our results. For instance, in one of the Norovirus tests we document here, EC 50 of 0.151 mcg/mL was reported. Even less mycophenolic acid would be needed to treat viruses such as Influenza A H1N1 and RSV in which we report EC50 <0.10 mcg/ml. Dramatically lower doses may suffice for mycophenolic acid to treat Zika virus, where a value of EC50 of 0.049 mcg/ml was obtained in one of our tests. Therefore, it is not only possible to achieve adequate body levels of mycophenolic acid to treat these viruses clinically, but also a small fraction of the current clinical dose may be more than adequate. To et al, 2016 also presented data on page 1812 supporting these conclusions.

A second beneficial difference in the administration of the mycophenolic acid for antiviral use compared to its current clinical usage is the following. Mycophenolic acid, when currently used clinically to prevent transplant rejection in an individual patient, typically is given for months or years at doses of 2000 mg to 3000 mg per day, to block lymphocyte cell proliferation. In contrast, the highly effective low dose antiviral treatments of the invention may require, for example, just one to two weeks of administration in an individual patient to cure his viral infection.

A third beneficial point is that the combination of low dose and short time of administration of mycophenolic acid to achieve the antiviral effect, is likely to drastically decrease the occurrence of those side effects (adverse events) which have typically been reported clinically where it is currently used at very high dose for very long periods of time. At low dose for short periods of time it is extremely unlikely to have immunosuppressive effects which could be detrimental to the body's resistance to other pathogens.

A fourth beneficial point is that the low dose, short time of administration usage described above may also serve to reduce the teratogenic potential of this drug, which occurs when it is used at high dose for long periods of time.

A fifth beneficial point regarding dosing and time of administration relates to those pathogenic infections which result in development of autoimmunity causing neurological illness such as Guillain-Barre Syndrome, encephalitis, myelitis, paralysis, confusion, weakness, etc. In those situations, for instance, the low effective antiviral dose can be titrated up so that an appropriate degree of mild immunosuppression is achieved simultaneously or shortly after the antiviral effect to block the autoimmunity from causing neurological illness. (It has been demonstrated that the immunosuppressive effect of mycophenolic acid on lymphocytes is dose- dependent, with lower doses having less effect (Vethe et al., 2008).)

For example, West Nile infection is well-documented to cause neurological illness. In a mouse model where West Nile infection leads to neurological illness, administration of appropriate doses of mycophenolic acid is demonstrated to mitigate the degree and occurrence of neurological illness.

Effectiveness of mycophenolic acid against influenza

1. Data supporting the effectiveness of mycophenolic acid in treating important and currently clinically relevant strains of influenza.

To et al. (2016) pointed out that the demonstration by Chan et al. (2013) of effectiveness of mycophenolic acid against the historical Influenza A(H1N1) strain A/WSN/1933 in a chemical screening assay, was insufficient to determine whether it would be effective against other strains of influenza. To et al. (2016) then experimentally showed that mycophenolic acid is effective against pandemic flu Hl/415, which is A/Hong Kong/415742/2009, and is sometimes written as A(HlNl)pdm09. They also showed it to be effective against seasonal influenza A(H3N2) virus, and avian-origin influenza A (H7N9), as well as other influenza A and influenza B viruses. These strains which they tested include those which are currently clinically relevant.

2. The invention provides for the use of mycophenolic acid to be active also against the following respiratory viruses: Influenza A H3N2; Influenza A H5N1 (low path); Influenza B (Victoria); Influenza B (Yamagata); Parainfluenza virus-3; Rhinovirus-14; Influenza A H7N9 virus; Influenza A H5N1 (high path).

In the VYR assays, MPA reduced virus to zero in Huh7 cells pre- incubated with drug for 24 hrs.

Minocycline, Doxycycline, and other Tetracycline derivatives for Zika treatment

The invention provides the use of minocycline, doxycycline and other tetracycline derivatives, including for example tetracycline, for the prevention and treatment of infection by pathogenic agents, for example viruses, and in a specific embodiment the Zika virus. Minocycline is a preferred compound because it will also cross the blood brain barrier. Without being bound by any theory, it is believed that the primary mechanism is inhibition of viral replication, but other properties including antioxidant and anti-inflammatory effects on the host cells are believed to contribute. Several tetracycline derivatives have been demonstrated to inhibit other viruses, including retroviruses and other flaviviridae (Chapagain, 2012; Dutta, 2010; Michaelis, 2007; Rothan, 2014).

L-DOPA, Dopamine, and precursors in the melanin synthesis pathway for Zika treatment

The invention provides that L-dopa, dopamine and precursors in the melanin synthesis pathway prevent and treat infection by Zika virus. L-DOPA is a preferred compound because it can be given orally and will also cross the blood brain barrier. Without being bound by any theory, the primary mechanism is believed to be inhibition of viral replication, but other properties including are believed to contribute. It has been proposed that in insects, several compounds in the melanin synthesis pathways are important in insect immunity and have antimicrobial effects (Nappi et al., 2005). L-Dopahas been demonstrated to reduce West Nile virus proliferation somewhat in cell culture, but the RNA levels of the virus were not reduced by L- Dopa (Blazquez et al., 2016). Blazquez, A.

Melanins

Melanin is a pigment which is found in many cells and organisms (Majerus, M. E. N., Melanism, New York: Oxford University Press 1998). It is resistant to analysis and degradation by chemical and physical agents (Prota, G., Melanins And Melanogenesis, New York: Academic Press, 1992). Therefore the complete structures of many melanins remain unknown, although a few have been identified and even synthesized (Prota, G., Melanins And Melanogenesis, New York: Academic Press, 1992).

Melanin is naturally found in small packets called melanosomes (Prota, G. , Melanins

And York: Academic Press, 1992), which are membrane- enclosed vesicles. Melanin is a hard substance (Majerus, M. E. N., Melanism, New York: Oxford University Press, 1998). The presence of many small melanosomes strengthens cells. The melanin in cells is separated by membranes and other cytoplasmic components, This arrangement permits flexibility in movement while preserving hardness to resist pressure.

Melanin is normally present in mammalian skin in cells called melanocytes (Prota, G. , Melanins And Melanogenesis, New York: Academic Press, 1992). Melanocytes are most numerous in the epidermis and dermis of the skin, but are present in other tissues such as the eye, some nerves, the brain, and some blood cells.

In the epidermis there is approximately 1 melanocyte to 36 keratinocytes. In the dermis the ratio of melanocytes to fibroblasts is much more variable. Melanin is often found in healed skin (Majerus, M. E. N., Melanism, New York: Oxford University Press, 1998).

Mammalian colors are determined chiefly by two types, eumelanins and phaeomelanins. Eumelanins are derived from the precursor tyrosine and are generally insoluble and black or brown in color. Phaeomelanins have as their precursors tyrosine and cysteine and are generally alkali-soluble and lighter in color. Allomelanins ("alio" meaning other) are formed from nitrogen-free precursors, primarily catechol and 1,8- dihydroxynaphthalene (see The Merck Index, Tenth Edition, page 827, item 5629, Melanins). Quinones are the usual intermediates in allomelanin synthesis. The synthesis of melanins occurs in nature as well as being produced synthetically. A further group of low molecular weight yellow, red and violet pigments is known as trichochromes. The trichochromes are usually classified with the melanins, since they serve as pigments and are derived from the oxidation of tyrosine.

The enzyme, tyrosinase, plays a key role in the synthesis of melanin and its derivatives. In mammals, tyrosinase is a glycosylated enzyme found in melanocytes. It has been theorized that tyrosinase functions by means of separate catalytic sites; one site for tyrosinase hydroxylase activity, another site for dopa oxidase activity, and a third independent site for dopa as a cofactor. (Hearing, V. J. et al. , Biochem. J. , 157: 549 (1976)). Tyrosinase may also play a role in catalyzing the oxidation of 5,6-dihydroxyindole to indole-5,6-quinone. (Korner, A. M. et al. , Science 217,1163 (1982)). In vivo, mammalian tyrosinase undergoes extensive modification. When initially synthesized, tyrosinase has an apparent molecular weight of about 55,000. Glycosylation of the enzyme occurs as it is transferred through the Golgi complex and delivered to the melanocytes. (Imokawa, G. et al. , J. Invest. Derm. , 85,165 (1985)). During this modification of tyrosinase, sialic acid and 4 mol of asparagine-linked carbohydrate chains (containing mannose, glucosamine, galactose and are added to each mole of tyrosinase. (Ferrini, V. et al. , Int. J. Biochem. 19,229 (1987)). The glycosylated tyrosinase has an apparent molecular weight of about 70,000. (Laskin, J. D. et al. , J. Biol. Chem. 261, 16626 (1986)). The glycosylated tyrosinase is delivered to the melanocytes by coated vesicles. In the melanocytes, the tyrosinase is membrane bound and aggregates into a high molecular weight form. In vivo, tyrosinase is under active metabolic control involving an active degradation system which results in a biological half- like of about ten hours. (Jimenez, M. et al. , Fed. Proc. Fedn. Am. Socs. Exp. Biol. 45,1714 (1986)).

The melanins comprise a family of biopolymer pigments. A frequently used chemical description of melanin is that it is comprised of "heteropolymers of 5-6-dihydroxyindole and 5- 6-dihydroxyindole-2-carboxylic acid" (Bettinger et al., 2009). Melanins are polymers produced by polymerization of reactive intermediates. The polymerization mechanisms include, but are not limited to, autoxidation, enzyme-catalyzed polymerization and free radical initiated polymerization. The reactive intermediates are produced chemically, electrochemically, or enzymatically from precursors. Suitable enzymes include, but are not limited to, peroxidases, catalases, polyphenol oxidases, tyrosinases, tyrosine hydroxylases, and laccases. The precursors that are connected to the reactive intermediates are hydroxylated aromatic compounds. Suitable hydroxylated aromatic compounds include, but are not limited to 1) phenols, polyphenols, aminophenols and thiophenols of aromatic or polycyclicaromatic hydrocarbons, including, but not limited to, phenol, tyrosine, pyrogallol, 3-aminotyrosine, thiophenol and a-naphthol; 2) phenols, polyphenols, aminophenols, and thiophenols of aromatic heterocyclic or heteropoly cyclic hydrocarbons such as, but not limited to, 2-hydroxypyrrole,4-hydroxy-l,2-pyrazole, 4- hydroxypyridine, 8-hydroxyquinoline, and 4,5-dihydroxybenzothiazole.

The term melanin includes naturally occurring melanin polymers as well as melanin analogs as defined below. Naturally occurring melanins include eumelanins, phaeomelanins, neuromelanins and allomelanins.

As used here, the term "melanin" refers to melanins, melanin precursors, melanin analogs, melanin variants, melanin derivatives, and melanin-like pigments, unless the context dictates otherwise. The term "melanin-like" also refers to hydrogels with melanin-like pigmentation and quinoid electrophilicity. This electrophilicity can be exploited for facile coupling with biomolecules.

As used herein, the term "melanin analog" refers to a melanin in which a structural feature that occurs in naturally-occurring or enzymatically-produced melanins is replaced by a substituent divergent from substituents traditionally present in melanin. An example of such a substituent is a selenium, such as selenocysteine, in place of sulfur.

As used herein, the term "melanin derivative" refers to any derivative of melanin which is capable of being converted to either melanin or a substance having melanin activity. An example of a melanin derivative is melanin attached to a dihydrotrigonelline carrier such as described in Bodor, N., Ann. N.Y. Acad. Sci. 507, 289 (1987), which enables the melanin to cross the blood- brain barrier. The term melanin derivatives is also intended to include chemical derivatives of melanin, such as an esterified melanin.

As used herein, the term "melanin variant" refers to various subsets of melanin substances that occur as families of related materials. Included in these subsets, but not limited thereto, are:

(1) Naturally occurring melanins produced by whole cells that vary in their chemical and physical characteristics;

(2) Enzymatically produced melanins prepared from a variety of precursor substrates under diverse reaction conditions;

(3) Melanin analogs in which a structural feature that occurs in (1) or (2) above is replaced by an unusual substituent divergent from the traditional; and

(4) Melanin derivatives in which a substituent in a melanin produced in (1), (2) or

(3) above is further altered by chemical or enzymatic means.

As used herein, the term "Melanin-like substances" refers to heteropolymers of 5-6- dihydroxyindole and 5-6-dihydroxyindole-2-carboxylic acid which have one or more properties usually associated with natural melanins, such as UV absorption or semiconductor behavior. Melanin Sources

Melanin and Melanin-like compounds can be obtained:

-by extraction and purification from natural sources, e.g. cephalopods such as cuttlefish (e.g. Sepia) or squid (e.g. Loligo), bird feathers (e.g. from species with black strains such as Silkie chickens);

-by chemical synthesis, whether water or non-water based e.g. (Deziderio, 2004) (daSilva et al., 2004; Lawrie et al., 2008; Pezzella et al., 2006);

-by electrochemical synthesis, e.g. (Meredith et al., 2005);

-by bioreactors created by utilization of natural or genetically altered bacteria, fungi, lichens, or viruses e.g.(della-Cioppa , 1998).

Melanin Manufacturing and Fabrication

Melanin and melanin-like compounds can be manufactured as particles, nanoparticles, dust, beads, or fibers that are woven or non- woven e.g. by methods as described by (Greiner and Wendorff, 2007), sheets e.g. (Meredith et al., 2005), films (daSilva et al., 2004), plates, bricks, chars, spheres, nodules, balls, graphite-like sheets and shards, liquids, gels, or solids (e.g. thermoplastic or thermoset), and by common chemical engineering molding and fabrication methods or custom methods. Sheets can range from one molecular layer to several millimeters. Fibers can range from nanometers to several millimeters.

The melanin material may be natural or synthetic, with natural pigments being extracted from plant and animal sources, such as squid, octopus, mushrooms, cuttlefish, and the like. In some cases, it may be desirable to genetically modify or enhance the plant or animal melanin source to increase the melanin production. Melanins are also available commercially from suppliers.

The following procedure describes an exemplary technique for the extraction of melanin from cuttlefish (Sepia Officinalis). 100 gm of crude melanin are dissected from the ink sac of 10 cuttlefish and washed with distilled water (3x100 ml). The melanin is collected after each wash by centrifugation (200xg for 30 minutes). The melanin granules are then stirred in 800 ml of 8 M Urea for 24 hours to disassemble the melanosomes. The melanin suspension is spun down at 22,000xg for 100 minutes and then washed with distilled water (5x400 ml). The pellet is washed with 50% aqueous DMF (5x400 ml) until a constant UV baseline is achieved from the washes. Finally, the pellet is washed with acetone (3x400 ml) and allowed to air dry.

Synthetic melanins may be produced by enzymatic conversion of suitable starting materials, as described in more detail hereinbelow. The melanins may be formed in situ within the porous particles or may be preformed with subsequent absorption into the porous particles.

Suitable melanin precursors include but are not limited to tyrosine, 3,4-dihydroxy phenylalanine (dopa), D-dopa, catechol, 5-hydroxyindole, tyramine, dopamine, m-aminophenol, o-aminophenol, p-aminophenol, 4-aminocatechol, 2-hydroxyl-l,4-naphthaquinone (henna), 4- methyl catechol, 3,4-dihydroxybenzylamine, 3,4-dihydroxybenzoic acid, 1,2- dihydroxynaphthalene, gallic acid, resorcinol, 2-chloroaniline, p-chloroanisole, 2-amino-p- cresol, 4,5-dihydroxynaphthalene 2,7-disulfonic acid, o-cresol, m-cresol, p-cresol, and other related substances which are capable of being oxidized to tan, brown, or black melanin-like compounds capable of absorbing ultraviolet radiation when incorporated in the polymeric particle matrix of the present invention. Combinations of precursors can also be used.

The melanin precursor is dissolved in an aqueous solution, typically at an elevated temperature to achieve complete solution. A suitable amount of the enzyme tyrosinase (EC 1.14.18.1) is added to the solution, either before or after the melanin precursor. The concentration of tyrosinase is not critical, typically being present in the range from about 50 to about 5000 U/ml. The solution is buffered with an acetate, phosphate, or other suitable buffer, to a pH in the range from about 3 to 10, usually in the range from about 5 to 8, more usually being about 7. Melanin- like pigments can be obtained using suitable precursors even in the absence of an enzyme just by bubbling oxygen through a solution of a precursor for an adequate period of time.

Melanin material may be obtained by treatment of, e.g, cuttlefish ink or squid ink in a microwave, optionally with mixing.

Pathogenic Infections

In a preferred embodiment the pathogen is an intracellular pathogen, i.e. a pathogen capable of growing and reproducing inside the cells of a host. Bacterial examples which may be prevented and/or treated by the compositons and methods of the invention include but are not limited to Francisella tularensis, Listeria monocytogenes, Salmonella, Brucella, Legionella, Mycobacterium, Nocardia, Rhodococcus equi, Yersinia, Neisseria meningitidis, Chlamydia, Rickettsia, Coxiella, Mycobacterium, such as Mycobacterium leprae and Treponema pallidum. Fungal examples include but are not limited to Histoplasma capsulatum, Cryptococcus neoformans and Pneumocystis jirovecii. Examples of protozoa include but are not limited to Apicomplexans (e.g. Plasmodium spp., Toxoplasma gondii and Cryptosporidium parvum) and Trypanosomatids (e.g. Leishmania spp. and Trypanosoma cruzi).

The following is an exemplary but non-limiting discussion of various disease agents that could be the subject of prevention and/or treatment in accordance with the present invention. Bacterial Pathogens

There are hundreds of bacterial pathogens in both the Gram-positive and Gram-negative families that cause significant illness and mortality around the word, despite decades of effort developing antibiotic agents. Antibiotic resistance is a growing problem in bacterial disease. Bacterial pathogens may be prevented and/or treated by the compositons and methods of the invention.

One of the bacterial diseases with highest disease burden is tuberculosis, caused by the bacterium Mycobacterium tuberculosis, which kills about 2 million people a year, mostly in sub- Saharan Africa. Pathogenic bacteria contribute to other globally important diseases, such as pneumonia, which can be caused by bacteria such as Streptococcus and Pseudomonas, and food borne illnesses, which can be caused by bacteria such as Shigella, Campylobacter, and Salmonella. Pathogenic bacteria also cause infections such as tetanus, typhoid fever, diphtheria, syphilis, and leprosy.

Conditionally pathogenic bacteria are only pathogenic under certain conditions, such as a wound facilitates entry of bacteria into the blood, or a decrease in immune function. For example, Staphylococcus or Streptococcus are also part of the normal human flora and usually exist on the skin or in the nose without causing disease, but can potentially cause skin infections, pneumonia, meningitis, and even overwhelming sepsis, a systemic inflammatory response producing shock, massive vasodilation and death. Some species of bacteria, such as Pseudomonas aeruginosa, Burkholderia cenocepacia, and Mycobacterium avium, are opportunistic pathogens and cause disease mainly in people suffering from immunosuppression or cystic fibrosis.

Other bacteria invariably cause disease in humans, such as obligate intracellular parasites (e.g., Chlamydophila, Ehrlichia, Rickettsia) that are capable of growing and reproducing only within the cells of other organisms. Still, infections with intracellular bacteria may be asymptomatic, such as during the incubation period. An example of intracellular bacteria is Rickettsia. One species of Rickettsia causes typhus, while another causes Rocky Mountain spotted fever. Chlamydia, another phylum of obligate intracellular parasites, contains species that can cause pneumonia or urinary tract infection and may be involved in coronary heart disease. Mycobacterium, Brucella, Francisella, Legionella, and Listeria can exist intracellular, though they are facultative (not obligate) intracellular parasites.

Fungal Pathogens

Pathogenic fungi are fungi that cause disease in humans or other organisms. The pathogenic fungi which may be prevented and/or treated by the compositons and methods of the invention include but are not limted to the following.

Candida species are important human pathogens that are best known for causing opportunist infections in immunocompromised hosts (e.g., transplant patients, AIDS sufferers, and cancer patients). Infections are difficult to treat and can be very serious. Aspergillus can and does cause disease in three major ways: through the production of mycotoxins; through induction of allergenic responses; and through localized or systemic infections. With the latter two categories, the immune status of the host is pivotal. The most common pathogenic species are Aspergillus fumigatus and Aspergillus flavus. Cryptococcus neoformans can cause a severe form of meningitis and meningo-encephalitis in patients with HIV infection and AIDS. The majority of Cryptococcus species lives in the soil and do not cause disease in humans. Cryptococcus laurentii and Cryptococcus albidus have been known to occasionally cause moderate-to- severe disease in human patients with compromised immunity. Cryptococcus gattii is endemic to tropical parts of the continent of Africa and Australia and can cause disease in non-immunocompromised people. Histoplasma capsulatum can cause histoplasmosis in humans, dogs and cats. Pneumocystis jirovecii (or Pneumocystis carinii) can cause a form of pneumonia in people with weakened immune systems, such as premature children, the elderly, transplant patients and AIDS patients. Stachybotrys chartarum or "black mold" can cause respiratory damage and severe headaches. It frequently occurs in houses in regions that are chronically damp.

Examples include Malassezia furfur; Exophiala werneckii; Microsporum species; Trichophyton species; Epidermophyton floccosum; Sporothrix schenckii; Phialophora verrucosa; Cladosporiumcarrinonii; Fonsecaea species; Coccidioides; Histoplasma capsulatum; Blastomyces dermatitidis; Cryptococcus neoformans; Cryptococcus gattii; Candida albicans; Aspergillus fumigatus; Aspergillus flavus; Aspergillus niger; Rhizopus; Rhizomucor; Mucor; Exserohilum.

Pharmaceutical Dosage Forms

The compositions of the present invention can be processed by agglomeration, air suspension chilling, air suspension drying, balling, coacervation, coating, comminution, compression, cryopelletization, encapsulation, extrusion, wet granulation, dry granulation, homogenization, inclusion complexation, lyophilization, melting, microencapsulation, mixing, molding, pan coating, solvent dehydration, sonication, spheronization, spray chilling, spray congealing, spray drying, or other processes known in the art. The compositions can be provided in the form of a minicapsule, a capsule, a tablet, an implant, a troche, a lozenge (mini tablet), a temporary or permanent suspension, an ovule, a suppository, a wafer, a chewable tablet, a quick or fast dissolving tablet, an effervescent tablet, a buccal or sublingual solid, a granule, a film, a sprinkle, a pellet, a bead, a pill, a powder, a triturate, a platelet, a strip or a sachet. Compositions can also be administered as a "dry syrup", where the finished dosage form is placed directly on the tongue and swallowed or followed with a drink or beverage. These forms are well known in the art and are packaged appropriately. The compositions can be formulated for oral, nasal, buccal, ocular, urethral, transmucosal, vaginal, topical or rectal delivery.

The pharmaceutical composition can be coated with one or more enteric coatings, seal coatings, film coatings, barrier coatings, compress coatings, fast disintegrating coatings, or enzyme degradable coatings . Multiple coatings can be applied for desired performance. Further, the dosage form can be designed for immediate release, pulsatile release, controlled release, extended release, delayed release, targeted release, synchronized release, or targeted delayed release. For release/absorption control, solid carriers can be made of various component types and levels or thicknesses of coats, with or without an active ingredient. Such diverse solid carriers can be blended in a dosage form to achieve a desired performance. The definitions of these terms are known to those skilled in the art. In addition, the dosage form release profile can be affected by a polymeric matrix composition, a coated matrix composition, a multiparticulate composition, a coated multiparticulate composition, an ion-exchange resin-based composition, an osmosis-based composition, or a biodegradable polymeric composition. Without wishing to be bound by theory, it is believed that the release may be effected through favorable diffusion, dissolution, erosion, ion-exchange, osmosis or combinations thereof.

When formulated as a capsule, the capsule can be a hard or soft gelatin capsule, a starch capsule, or a cellulosic capsule. Although not limited to capsules, such dosage forms can further be coated with, for example, a seal coating, an enteric coating, an extended release coating, or a targeted delayed release coating. These various coatings are known in the art, but for clarity, the following brief descriptions are provided: seal coating, or coating with isolation layers: Thin layers of up to 20 microns in thickness can be applied for variety of reasons, including for particle porosity reduction, to reduce dust, for chemical protection, to mask taste, to reduce odor, to minimize gastrointestinal irritation, etc. The isolating effect is proportional to the thickness of the coating. Water soluble cellulose ethers are preferred for this application. HPMC and ethyl cellulose in combination, or Eudragit E100, may be particularly suitable for taste masking applications. Traditional enteric coating materials listed elsewhere can also be applied to form an isolating layer.

Extended release coatings are designed to effect delivery over an extended period of time. The extended release coating is a pH-independent coating formed of, for example, ethyl cellulose, hydroxypropyl cellulose, methylcellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, acrylic esters, or sodium carboxymethyl cellulose. Various extended release dosage forms can be readily designed by one skilled in art to achieve delivery to both the small and large intestines, to only the small intestine, or to only the large intestine, depending upon the choice of coating materials and/or coating thickness.

Enteric coatings are mixtures of pharmaceutically acceptable excipients which are applied to, combined with, mixed with or otherwise added to the carrier or composition. The coating may be applied to a compressed or molded or extruded tablet, a gelatin capsule, and/or pellets, beads, granules or particles of the carrier or composition. The coating may be applied through an aqueous dispersion or after dissolving in appropriate solvent. Additional additives and their levels, and selection of a primary coating material or materials will depend on the following properties: 1. resistance to dissolution and disintegration in the stomach; 2. impermeability to gastric fluids and drug/carrier/enzyme while in the stomach; 3. ability to dissolve or disintegrate rapidly at the target intestine site; 4. physical and chemical stability during storage; 5. non-toxicity; 6. easy application as a coating (substrate friendly); and 7. economical practicality. Dosage forms of the compositions of the present invention can also be formulated as enteric coated delayed release oral dosage forms, i.e., as an oral dosage form of a pharmaceutical composition as described herein which utilizes an enteric coating to affect release in the lower gastrointestinal tract. The enteric coated dosage form may be a compressed or molded or extruded tablet/mold (coated or uncoated) containing granules, pellets, beads or particles of the active ingredient and/or other composition components, which are themselves coated or uncoated. The enteric coated oral dosage form may also be a capsule (coated or uncoated) containing pellets, beads or granules of the solid carrier or the composition, which are themselves coated or uncoated.

Delayed release generally refers to the delivery so that the release can be accomplished at some generally predictable location in the lower intestinal tract more distal to that which would have been accomplished if there had been no delayed release alterations. The preferred method for delay of release is coating. Any coatings should be applied to a sufficient thickness such that the entire coating does not dissolve in the gastrointestinal fluids at pH below about 5, but does dissolve at pH about 5 and above. It is expected that any anionic polymer exhibiting a pH- dependent solubility profile can be used as an enteric coating in the practice of the present invention to achieve delivery to the lower gastrointestinal tract. Polymers for use in the present invention are anionic carboxylic polymers.

Shellac, also called purified lac, a refined product obtained from the, resinous secretion of an insect. This coating dissolves in media of pH>7. Colorants, detackifiers, surfactants, antifoaming agents, lubricants, stabilizers such as hydroxy propyl cellulose, acid/base may be added to the coatings besides plasticizers to solubilize or disperse the coating material, and to improve coating performance and the coated product.

In carrying out the method of the present invention, the combination of the invention may be administered to mammalian species, such as dogs, cats, humans, etc. and as such may be incorporated in a conventional systemic dosage form, such as a tablet, capsule, elixir or injectable. The above dosage forms will also include the necessary carrier material, excipient, lubricant, buffer, antibacterial, bulking agent (such as mannitol), anti-oxidants (ascorbic acid of sodium bisulfite) or the like.

The dose administered must be carefully adjusted according to age, weight and condition of the patient, as well as the route of administration, dosage form and regimen and the desired result. The pharmaceutical compositions of the invention may be administered in the dosage forms in single or divided doses of one to four times daily. It may be advisable to start a patient on a low dose combination and work up gradually to a high dose combination.

Tablets of various sizes can be prepared, e.g., of about 1 to 2000 mg in total weight, containing one or both of the active pharmaceutical ingredients, with the remainder being a physiologically acceptable carrier of other materials according to accepted pharmaceutical practice. These tablets can be scored to provide for fractional doses. Gelatin capsules can be similarly formulated.

Liquid formulations can also be prepared by dissolving or suspending one or the combination of active substances in a conventional liquid vehicle acceptable for pharmaceutical administration so as to provide the desired dosage in one to four teaspoonful.

Dosage forms can be administered to the patient on a regimen of, for example, one, two, three, four, five, six, or other doses per day

In order to more finely regulate the dosage schedule, the active substances may be administered separately in individual dosage units at the same time or carefully coordinated times. Since blood levels are built up and maintained by a regulated schedule of administration, the same result is achieved by the simultaneous presence of the two substances. The respective substances can be individually formulated in separate unit dosage forms in a manner similar to that described above.

In formulating the compositions, the active substances, in the amounts described above, may be compounded according to accepted pharmaceutical practice with a physiologically acceptable vehicle, carrier, excipient, binder, preservative, stabilizer, flavor, etc., in the particular type of unit dosage form.

Illustrative of the adjuvants which may be incorporated in tablets are the following: a binder such as gum tragacanth, acacia, corn starch or gelatin; an excipient such as dicalcium phosphate or cellulose; a disintegrating agent such as corn starch, potato starch, alginic acid or the like; a lubricant such as stearic acid or magnesium stearate; a sweetening agent such as sucrose, aspartame, lactose or saccharin; a flavoring agent such as orange, peppermint, oil of wintergreen or cherry. When the dosage unit form is a capsule, it may contain in addition to materials of the above type a liquid carrier such as a fatty oil. Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets or capsules may be coated with shellac, sugar or both. A syrup of elixir may contain the active compound, water, alcohol or the like as the carrier, glycerol as solubilizer, sucrose as sweetening agent, methyl and propyl parabens as preservatives, a dye and a flavoring such as cherry or orange.

One embodiment of this invention includes methods of treating, preventing, or diagnosing a particular disease or condition by administering the disclosed nanoparticles, composite nanoparticles, nanosuspension, or nanocapsules to a subject. In many instances, the nanoparticles, composite nanoparticles, or nanocapsules are administered alone or can be included within a pharmaceutical composition. An effective amount of a pharmaceutical composition, generally, is defined as that amount sufficient to ameliorate, reduce, minimize, or limit the extent of the disease or condition. More rigorous definitions may apply, including elimination, eradication, or cure of the disease or condition.

"Nanoparticles" are solid particles of an average particle diameter of, for example, less than about 1 micron (micrometer). One micron is 1,000 nanometers (nm). "Stabilized" nanoparticles are nanoparticles coated with a stabilizing material and having a reduced tendency for aggregation and loss of dispersion with respect to nanoparticles of the compound of the invention without a stabilizing coating. A nano-spray is a spray containing nanoparticles or a spray that produces nanoparticles. A nanodispersion is a dispersion containing nanoparticles. A nanosuspension is a suspension containing nanoparticles.

The liquid formulations useful herein may comprise a solvent, solution, suspension, microsuspension, nanosuspension, emulsion, microemulsion, gel or even a melt containing the active component or components. In some embodiments the nanoparticles, nanofibers, or nanofibrils may be in the form of, or within or on, granules, powders, suspensions, solutions, dissolvable films, mats, webs, tablets, orreleasable forms particularly releasable dosage forms. Other particular useful forms are concentrates to which a diluting liquid is added prior to use. The product may also be sprayed onto the inner surface of a container to which a liquid is added later prior to use and the nanoparticles, nanofibers, or nanofibrils, are released into the liquid. Pharmaceutical compositions of the present invention can include nanoparticles, composite nanoparticles, nanosuspension, or nanocapsules of the present invention.

The composition may also include various antioxidants to retard oxidation of one or more active ingredient or nanoparticles, composite nanoparticles, nanosuspension, or nanocapsules. The prevention of the action of microorganisms can be brought about by preservatives such as various antibacterial and antifungal agents, including but not limited to parabens (e.g., methylparabens, propylparabens), chlorobutanol, phenol, sorbic acid, thimerosal or combinations thereof. In order to increase the effectiveness of a treatment with the nanoparticles, nanogels, composite nanoparticles, nanosuspension, or nanocapsules of the present invention, it may be desirable to combine these nanoparticles, composite nanoparticles, or nanocapsules with other therapies effective in the treatment of a particular disease or condition.

The formulations as described above may be administered for a prolonged period, that is, for as long as the potential for a disease or condition remains or the symptoms continue. Neurological Symptoms

Mvcophenolic Acid and Zika Neurological Disease

The invention provides that mycophenolic acid and the other pharmaceutical compositions and methods of the invention will prevent, mitigate, and treat neurological disease resulting from infection by Zika virus.

Neurological sequelae of Zika infection include: Guillain Barre Syndome, encephalitis, myelitis, encephalomyelitis, meningitis, meningoencephalitis, facial paralysis, confusion, weakness, cognitive dysfunction and other neurological disorders (Araujo et al., 2016). Many of these neurological complications are believed to be due to autoimmune responses to the viral infection which lead to immunological cells of the human body attacking nerves and supporting cells. Mycophenolate is a rather unique antiviral drug in that at high doses it has clinically impressive immunosuppressive properties. It has been discovered that by providing doses of mycophenolic acid that are above the minimum dose required for its antiviral effect but generally below the high doses used clinically for prevention of transplantation rejection, that neurological sequelae of Zika virus infection can be prevented, mitigated, and treated.

Mvcophenolic Acid and Neurological diseases due to other viruses

In addition to Zika, other viruses are well known to have neurological sequellae, including West Nile virus (Morrey et al. , 2013), influenza virus (Cardenas et al., 2014, norovirus (Chen et al., 2009), dengue virus (Sil et al., 2017), and other flaviviridae (Soloman et al., 2016). The invention provides for the use of mycophenolic acid which can prevent and treat neurological sequelae of other viruses including the above.

Morrey et al., 2013, reviewed mouse and hamster models for neurological sequelae of

West Nile virus and showed how the animal models compare to the human neurological sequelae. The mouse model is utilized to demonstrate that administration of mycophenolic acid after infection with West Nile virus prevents and treats a range of neurological diseases and symptoms caused by West Nile virus. The invention provides for the use of mycophenolic acid in preventing and treating neurological sequelae of viral diseases is enhanced by simultaneously administering a low nucleotide diet, and especially a low-guanosine diet. Limiting the availability of guanosine from the diet reduces the body pool of guanosine, thus enhancing the guanosine lowering effect of mycophenolic acid, which is responsible for its antiviral and anti-inflammatory and immunosuppressive properties.

In addition, the invention provides a method of preventing and/or treating postviral neurological syndromes in a patient, the method comprising the steps of: selecting a patient in need of preventing and/or treating postviral neurological syndrome; administering to the patient at least one agent selected from the group consisting of minocycline, doxycycline, tetracycline, tetracycline derivatives, L-DOPA, dopamine, and combinations thereof; wherein the postvirasl neurological syndrome is prevented and/or treated in the patient. The invention provides a method wherein the postviral neurological syndromes is as a result of infection by a virus selected from the group consisting of Zika virus, Norovirus, Respiratory Syncytial Virus, Influenza, Adenovirus 5, HPV 11, Lassa Fever virus, Powassan virus, Rift Valley virus, and combinations thereof. The invention provides a method wherein at least one agent is administered in topical form.

Packaging/Treatment Kits

The present invention relates to a kit for conveniently and effectively carrying out the methods in accordance with the present invention. Such kits may be suited for the delivery of solid oral forms such as tablets or capsules. Such a kit may include a number of unit dosages. Such kits can include a means for containing the dosages oriented in the order of their intended use. An example of a means for containing the dosages in the order of their intended uses is a card. An example of such a kit is a "blister pack". Blister packs are well known in the packaging industry and are widely used for packaging pharmaceutical unit dosage forms. If desired, the blister can be in the form of a childproof blister, i.e., a blister that is difficult for a child to open, yet can be readily opened by an adult. If desired, a memory aid can be provided, for example in the form of numbers, letters, or other markings or with a calendar feature and/or calendar insert, designating the days and the sections of a day in the treatment schedule in which the dosages can be administered, such as an AM dose is packaged with a "mid day" and a PM dose.; or an AM dose is packaged with a PM dose. Alternatively, placebo dosages, or vitamin or dietary supplements, either in a form similar to or distinct from the pharmaceutical active dosages, can be included.

Blister packs, clamshells or trays are forms of packaging used for goods; thus, the invention provides for blister packs, clamshells or trays comprising a composition (e.g., a (the multi-ingredient combination of drugs of the invention) combination of active ingredients) of the invention. Blister packs, clamshells or trays can be designed to be non-reclosable, so consumers can tell if a package has already opened. They are used to package for sale goods where product tampering is a consideration, such as the pharmaceuticals of the invention. In one aspect, a blister pack of the invention comprises a moulded PVC base, with raised areas (the "blisters") to contain the tablets, pills, etc. comprising the combinations of the invention, covered by a foil laminate. Tablets, pills, etc. are removed from the pack either by peeling the foil back or by pushing the blister to force the tablet to break the foil. In one aspect, a specialized form of a blister pack is a strip pack.

In one aspect, a blister pack also comprises a method of packaging where the compositions comprising combinations of ingredients of the invention are contained in-between a card and a clear PVC. The PVC can be transparent so the item (pill, tablet, geltab, etc.) can be seen and examined easily; and in one aspect, can be vacuum- formed around a mould so it can contain the item snugly and have room to be opened upon purchase. In one aspect, the card is brightly colored and designed depending on the item (pill, tablet, geltab, etc.) inside, and the PVC is affixed to the card using pre-formed tabs where the adhesive is placed. The adhesive can be strong enough so that the pack may hang on a peg, but weak enough so that this way one can tear open the join and access the item. Sometimes with large items or multiple enclosed pills, tablets, geltabs, etc., the card has a perforated window for access. In one aspect, more secure blister packs, e.g., for items such as pills, tablets, geltabs, etc. of the invention are used, and they can comprise of two vacuum-formed PVC sheets meshed together at the edges, with the informative card inside.

In one aspect, blister packaging comprises at least two components (e.g., is a multi- ingredient combination of drugs of the invention): a thermoformed "blister" which houses the product (e.g., a pharmaceutical combination of the invention), and then a "blister card" that is a printed card with an adhesive coating on the front surface. During the assembly process, the blister component, which is most commonly made out of PVC, is attached to the blister card using a blister machine. This machine introduces heat to the flange area of the blister which activates the glue on the card in that specific area and ultimately secures the PVG blister to the printed blister card. The thermoformed PVG blister and the printed blister card can be as small or large.

As discussed herein, the products of manufacture of the invention can comprise the packaging of the therapeutic drug combinations of the invention, alone or in combination, as "blister packages" or as a plurality of packettes, including as lidded blister packages, lidded blister or blister card or packets, or a shrink wrap.

Other means for containing said unit dosages can include bottles and vials, wherein the bottle or vial comprises a memory aid, such as a printed label for administering said unit dosage or dosages. The label can also contain removable reminder stickers for placement on a calendar or dayminder to further help the patient to remember when to take a dosage or when a dosage has been taken.

Topical Formulations

The term "topical" as employed herein relates to the use of a compound, derivative or analogue as described herein, incorporated in a suitable pharmaceutical carrier, and applied at the site for exertion of local action. Accordingly, such topical compositions including those forms in which the compound is applied externally by direct contact with the skin surface to be treated. Conventional forms for this purpose include ointments, liniments, creams, shampoos, lotions, pastes, jellies, sprays, aerosols, soaps, and the like, and may be applied in patches or impregnated dressings depending on the part of the body to be treated. The term "ointment" embraces formulations (including creams) having oleaginous, absorption, water-soluble and emulsion-type bases, e.g., petrolatum, lanolin, polyethylene glycols, as well as mixtures of these.

For topical use, the agent of the invention can be advantageously formulated using ointments, creams, liniments or patches as a carrier of the active ingredients. Also, these formulations may or may not contain preservatives, depending on the dispenser and nature of use. Such preservatives include those mentioned above, and methyl-, propyl-, or butyl- parahydroxybenzoic acid, betain, chlorhexidine, benzalkonium chloride, and the like. Various matrices for slow release delivery may also be used. Typically, the dose to be applied is in the range of about 0.1 ng to about 100 mg per day, or about 1 ng to about 10 mg per day, or about 10 ng to about 1 mg per day depending on the formulation. Non- limiting examples of topical products can include, without limitation, application stick, mascara, eyebrow coloring products, eye shadow or other eye lid coloring products, eyeliner, make-up removal products, antiaging products, facial or body powder, nail polish, mousse, sprays, styling gels, nail conditioner, bath and shower gels, shampoos, conditioners, cream rinses, hair dyes and coloring products, hair conditioners, sun tanning lotions and creams and sprays, sunscreens and sunblocks, skin conditioners, cold creams, moisturizers, hair sprays, soaps, body scrubs, exfoliants, astringents, depilatories and permanent waving solutions, antidandruff formulations, antisweat and antiperspirant compositions, shaving, preshaving and after shaving products, moisturizers, deodorants, cold creams, cleansers, skin gels, and rinses.

Furthermore, the topical product can be applied topically through the use of a patch or other delivery device. Delivery devices can include, but are not limited to, those that can be heated or cooled, as well as those that utilize iontophoresis or ultrasound.

For instance, the topical product can be applied, for example, by applying a composition in the form of a skin lotion, clear lotion, milky lotion, cream, gel, foam, ointment, paste, emulsion, spray, conditioner, tonic, cosmetic, application stick, pencil, foundation, nail polish, after-shave, or the like which is intended to be left on the skin or other keratinous tissue (i.e., a "leave-on" composition). After applying the composition to the keratinous tissue (e.g., skin), it in one embodiment, it is left on for a period of at least about 15 minutes, or at least about 30 minutes, or at least about 1 hour, or for at least several hours, e.g., up to about 12 hours. In one embodiment, the topical product is left on overnight. In another embodiment, the topical product is left on all day. Any part of the external portion of the face, hair, and/or nails can be treated, (e.g., face, lips, under-eye area, eyelids, scalp, neck, torso, arms, legs, chest, hands, legs, feet, fingernails, toenails, scalp hair, eyelashes, eyebrows, etc.).

Any suitable method can be used to apply the topical product, including but not limited to for example using the palms of the hands and/or fingers or a device or implement (e.g., a cotton ball, swab, pad, applicator pen, spray applicator, eyebrow brush, eyebrow brush pencil, pencil, mascara brush, etc.) Another approach to ensure a continuous exposure of the keratinous tissue to at least a minimum level of the topical product is to apply the compound by use of a patch applied, e.g., to the face. The patch can be occlusive, semi-occlusive or non-occlusive, and can be adhesive or non-adhesive. The topical product can be contained within the patch or be applied to the skin prior to application of the patch. The patch can also include additional actives such as chemical initiators for exothermic reactions. The patch can be left on for any suitable period of time. For example, a period of at least about 5 minutes, or at least about 15 minutes, or at least about 30 minutes, or at least about 1 hour, or at night as a form of night therapy, or in another embodiment all day.

Administration

The pharmaceutical compositions may be optimized for particular types of delivery. For example, pharmaceutical compositions for oral delivery are formulated using pharmaceutically acceptable carriers that are well known in the art. The carriers enable the agents in the composition to be formulated, for example, as a tablet, pill, capsule, solution, suspension, sustained release formulation; powder, liquid or gel for oral ingestion by the subject.

The liquid or solid compositions may contain suitable pharmaceutically acceptable excipients as set out above. Preferably the compositions are administered by the oral, intranasal or respiratory route for local or systemic effect. Compositions in preferably sterile pharmaceutically acceptable solvents may be nebulized by use of inert gases. Nebulized solutions may be breathed directly from the nebulizing device or the nebulizing device may be attached to a face mask, tent or intermittent positive pressure breathing machine. Solution, suspension or powder compositions may be administered, preferably orally or nasally, from devices that deliver the formulation in an appropriate manner.

Typically, the composition may be applied repeatedly for a sustained period of time topically on the part of the body to be treated, for example, the eyelids, eyebrows, skin or scalp. The dosage regimen will generally involve regular, such as daily, administration for a period of treatment of at least one month, or at least three months, or at least six months.

Alternatively, the composition may be applied intermittently, or in a pulsed manner. Accordingly, an alternative embodiment of the invention is to apply the composition on an intermittent or pulsed dosage schedule. For example, the composition of the invention may be used for two or more days, stopped, then restarted again at a time from between 2 weeks to 3 months later, and at even more long-spaced intervals in the case of the scalp.

The treatments may include various "unit doses." Unit dose is defined as containing a predetermined-quantity of the therapeutic composition. The quantity to be administered, and the particular route and formulation, are within the skill of those in the clinical arts. A unit dose need not be administered as a single injection but may comprise continuous infusion over a set period of time. Alternatively, the amount specified may be the amount administered as the average daily, average weekly, or average monthly dose.

The invention will be illustrated in more detail with reference to the following Examples, but it should be understood that the present invention is not deemed to be limited thereto.

EXAMPLES

Example 1.

Prevention and treatment of a male at risk for Zika infection

In this example, the new method prevents or minimizes infection of humans by Zika virus. Here, a male at risk for being stung by an Aedes mosquito takes the following steps. He starts taking daily low dose oral mycophenolate one week before he travels to a Zika infested area and continues taking it while in the area. He applies a melanin containing lotion daily to skin not covered by clothing.

The use of these methods inhibits the infection in the following ways.

1. The lotion containing melanin is applied to the skin and is partially absorbed into the epidermis and dermis. It rapidly evaporates to leave a thin tough film. The external film of melanin minimizes or entirely prevents the entry of the virus in the skin from the stinger of the Aedes mosquito vector. If any virus is successfully injected into the epidermis or dermis, the absorbed melanin, which is toxic to the virus but not to human cells, eliminates or reduces the amount of live virus which has been introduced.

2. It has been demonstrated that three types of cells in the skin are normally susceptible to infection by the Zika virus: epidermal keratinocytes, dermal fibroblasts, and (dermal) macrophages. It has also been demonstrated that mycophenolate dramatically reduces guanosine levels in all three cell types. Thus because of relative depletion of guanosine in these cells, there is reduced (or absent) replication of the viral RNA in these cells as the guanosine necessary for replication of RNA is in short supply. Thus viral particles injected are only able to reproduce at a lower amount, or not at all, minimizing or terminating the infective load.

3. If in spite of the prior steps, the virus is successful in penetrating to the blood stream and causing a viremia, the systemic mycophenolate directly inhibits the the replication of the Zika virus in the blood and throughout the body. 4. Note that since a very small amount of antigen is known to trigger the immune system responses, it is likely that even if the injected viral load is partially destroyed and the ability of remaining virus particles to replicate is limited, there is likely to be adequate viral antigen to stimulate the normal antiviral responses of the innate and adaptive immune systems.

Example 2.

Prevention and treatment of a female at risk for pregnancy and Zika infection.

Here, a female who is sexually active and may become pregnant is at risk for being stung by an Aedes mosquito and takes the following steps. She starts on a reduced guanosine diet designed for women who are pregnant or may become pregnant, one week before she travels to a Zika infested area and continues adhering to this diet while in the area. She applies a melanin containing lotion daily to skin not covered by clothing.

1. The lotion containing melanin is applied to the skin and is partially absorbed into the epidermis and dermis. It rapidly evaporates to leave a thin tough film. The external film of melanin minimizes or entirely prevents the entry of the virus in the skin from the stinger of the Aedes mosquito vector. If any virus is successfully injected into the epidermis or dermis, the absorbed melanin, which is toxic to the virus but not to human cells, eliminates or reduces the amount of live virus which has been introduced.

2. It has been demonstrated that three types of cells in the skin are normally susceptible to infection by the Zika virus: epidermal keratinocytes, dermal fibroblasts, and (dermal) macrophages. The reduced guanosine diet reduces guanosine levels in all three cell types. Thus because of relative depletion of guanosine in these cells, there is reduced (or absent) replication of the viral RNA in these cells as the guanosine necessary for replication of RNA is in short supply. Thus viral particles injected are only able to reproduce at a lower amount, or not at all, minimizing or terminating the infective load.

3. If in spite of the prior steps, the virus is successful in penetrating to the blood stream and causing a viremia, the relative lack of guanosine caused by the reduced diet limits the ability of the virus to replicate.

4. The above steps are successful in interdicting the infection sufficiently that an embryo or fetus is not damaged by the maternal viral infection.

Example 3

Treatment of a patient with multi-drug resistant tuberculosis.

A traveler from the US contracts multi-drug resistant tuberculosis while in India. There are no known effective antibiotics. The patient is administered 3 ounces (about 90 gm) of cuttlefish ink (which contains melanin) mixed in his regular food twice per day for two weeks. Then mycophenolate mofetil 250mg twice per day is added. The regimen is continued for 3 months leading to cure of the multidrug-resistant tuberculosis.

Example 4

Treatment of a patient with infectious pulmonary aspergillosis.

As asthma patient contracts infectious pulmonary aspergillosis, a fungal disease. The patient is administered 2 grams of melanin (1 gm/capsule) mixed in his regular food twice per day for two weeks. Then mycophenolate mofetil 250mg twice per day is added. The regimen is continued for 3 months leading to cure of the aspergillosis.

Example 5

Diets with reduced guanosine content

These invented diets are low in nucleic acids and their components but are not nucleotide-free. The diets contain approximately 3% to 50% of the amount by weight of nucleotides seen in the normal western diet (2000 mg/day, from Ekelman, K. Disodium 5'Guanylate and Disodium 5'-Inosate. WHO Food Additives Series, No. 32 (1993), and preferably 10%-40%.

The inventor has conducted extensive analysis of the nucleotide content of human foods from a variety of sources, and evaluated the nutritional content and palatability of potential nucleotide-free diets. The inventor has concluded that it is not practical for most people to stay on a nucleotide-free diet in a compliant manner for the period of months required to obtain substantial clinical benefit from this approach. A nucleotide-free diet is unlikely to be sufficiently palatable for extended use and would deter compliance. Also, use of a nucleotide- free diet for months in humans would likely lead to other dietary deficiencies.

As set forth above, the invention provides treatment of a patient with a diet which contains approximately 3% to 50% of the amount by weight of nucleotides seen in the normal western diet, which contains about 2000 mg/day of nucleotides. In exemplary embodiments, the diet of the invention contains a nucleotide content of about 1000 mg/day, of about 750 mg/day, of about 500 mg/day, of about 250 mg/day, of about 100 mg/day, of about 75 mg/day, of about 50 mg/day, of about 25 mg/day. In exemplary embodiments, the diet of the invention contains a nucleotide content compared to the normal Western diet of about 50%, of about 40%, of about 30%, of about 20%, of about 10%, of about 5%, of about 3%. In exemplary embodiments, the diet of the invention contains a nucleotide content compared to the normal Western diet of 3- 50%, of about 10-40%, of about 20-30%, of about 3-40%, of about 3-30%, of about 10-30%, of about 10-20%.

Example 6

Diets with reduced guanosine content optimized for women who are pregnant or may become pregnant.

The diets in Example 5 are modified to make them appropriate for women who are pregnant. The modified diets contain additional calcium, trace minerals, and B vitamin supplements. A supplement like Ensure or Boost would be added to the diet. There would be additional fatty acids and protein.

Example 7

In vitro demonstration of method efficacy

Using methods similar to those of Diamond et al, 2002, (Diamond, M., Zachariah, M, and Harris, E. "Mycophenolic Acid Inhibits Dengue Virus Infection by Preventing Replication of Viral RNA." Virology 304, no. 2 (2002): 211-221) mycophenolate and melanin are shown together, or when administered sequentially, to inhibit the replication of the Zika virus in vitro. For example, Zika virus is added to monolayers of hepatoma cells or hamster kidney cells at several different doses. They are incubated for 2 hours at a temperature of 37C. The cells are washed several times. Mycophenolate or melanin or both are added to the cells after they are exposed to Zika. After 72 hours the cells are harvested. RNA, viral antigen, and virion are quantitated. The results show that mycophenolate and melanin together inhibit almost all replication of the Zika virus. Depending on the type of cells used, the dose of Zika virus, the doses of mycophenolate and/or melanin, the viral replication is inhibited in various degrees. Example 8.
