ANTI-VIRAL COMPOSITIONS AND METHODS OF PRODUCTION AND USE THEREOF

CROSS REFERENCE TO RELATED APPLICATIONS/INCORPORATION BY REFERENCE STATEMENT

[0001] Not Applicable.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not applicable.

BACKGROUND

[0003] Mosquito-borne viruses such as (but not limited to) Chikungunya virus (CHIKV), Dengue virus (DENV), Zika virus (ZIKV), Yellow Fever virus (YFV), Japanese Encephalitis virus (JEV), and West Nile virus (WNV) are major global health challenges that affect hundreds of millions of people worldwide. Mosquito-borne viruses are increasingly prevalent due to the geographical expansion of mosquito vectors due to global warming.

[0004] Recent unprecedented outbreaks of CHIKV and DENV in Asian countries (including India) and WNV in Europe have led to an urgent need for therapies to treat mosquito-borne viral infections; however, no approved specific treatments and therapies are currently available for mosquito-borne viral infections. Though post-bite topical applications are available on the market, these compositions typically only provide itch relief and/or wound healing properties, and do not possess any specific anti-viral activities. In addition, the continuous rise in mosquito borne illnesses clearly indicates the ineffectiveness of mosquito repellents and traps that are currently available. Therefore, preparedness for mosquito-borne viral epidemics are extremely important public health priorities, as vector borne viral transmission is rapidly accelerating every year with unpredictable outbreaks. [0005] Several challenges have been encountered in the development of broadspectrum antiviral therapies for treating mosquito-borne viral infections. First, most of these infections are acute, leading to a short time window for therapy. Second, many mosquito-borne viral infections often co-circulate/co-infect in the same geographical regions and exhibit overlapping clinical symptoms in patients, thus making diagnosis and treatment more complicated. Thus, disrupting the virus cycle at its source has clear advantages in breaking the chain of infection and spread of disease.

[0006] Thus, there is a need in the art for new and improved anti-viral compositions to treat mosquito-borne infections and other arthropod-borne infections (such as, but not limited to, tick-, flea-, fly-, midge-, and mite-borne infections), as well as other types of viral infections. It is to such new and improved compositions, as well as methods of production and use thereof, that the present disclosure is directed.

DETAILED DESCRIPTION

[0007] Before explaining at least one embodiment of the inventive concept(s) in detail by way of exemplary language and results, it is to be understood that the inventive concept(s) is not limited in its application to the details of construction and the arrangement of the components set forth in the following description. The inventive concept(s) is capable of other embodiments or of being practiced or carried out in various ways. As such, the language used herein is intended to be given the broadest possible scope and meaning; and the embodiments are meant to be exemplary - not exhaustive. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.

[0008] Unless otherwise defined herein, scientific and technical terms used in connection with the presently disclosed inventive concept(s) shall have the meanings that are commonly understood by those of ordinary skill in the art. Further, unless otherwise required by context, singular terms shall include pluralities and plural terms shall include the singular. The foregoing techniques and procedures are generally performed according to conventional methods well known in the art and as described in various general and more specific references that are cited and discussed throughout the present specification. The nomenclatures utilized in connection with, and the laboratory procedures and techniques of, analytical chemistry, synthetic organic chemistry, and medicinal and pharmaceutical chemistry described herein are those well- known and commonly used in the art. Standard techniques are used for chemical syntheses and chemical analyses.

[0009] All patents, published patent applications, and non-patent publications mentioned in the specification are indicative of the level of skill of those skilled in the art to which this presently disclosed inventive concept(s) pertains. All patents, published patent applications, and non-patent publications referenced in any portion of this application are herein expressly incorporated by reference in their entirety to the same extent as if each individual patent or publication was specifically and individually indicated to be incorporated by reference.

[00010] All of the compositions and/or methods disclosed herein can be made and executed without undue experimentation in light of the present disclosure. While the compositions and methods of the inventive concept(s) have been described in terms of particular embodiments, it will be apparent to those of skill in the art that variations may be applied to the compositions and/or methods and in the steps or in the sequence of steps of the methods described herein without departing from the concept, spirit, and scope of the inventive concept(s). All such similar substitutions and modifications apparent to those skilled in the art are deemed to be within the spirit, scope, and concept of the inventive concept(s) as defined by the appended claims.

[0011] As utilized in accordance with the present disclosure, the following terms, unless otherwise indicated, shall be understood to have the following meanings:

[0012] The use of the term "a" or "an" when used in conjunction with the term "comprising" in the claims and/or the specification may mean "one," but it is also consistent with the meaning of "one or more," "at least one," and "one or more than one." As such, the terms "a," "an," and "the" include plural referents unless the context clearly indicates otherwise. Thus, for example, reference to "a compound" may refer to one or more compounds, two or more compounds, three or more compounds, four or more compounds, or greater numbers of compounds. The term "plurality" refers to

"two or more."

[0013] The use of the term "at least one" will be understood to include one as well as any quantity more than one, including but not limited to, 2, 3, 4, 5, 10, 15, 20, 30, 40, 50, 100, etc. The term "at least one" may extend up to 100 or 1000 or more, depending on the term to which it is attached; in addition, the quantities of 100/1000 are not to be considered limiting, as higher limits may also produce satisfactory results. In addition, the use of the term "at least one of X, Y, and Z" will be understood to include X alone, Y alone, and Z alone, as well as any combination of X, Y, and Z. The use of ordinal number terminology (i.e., "first," "second," "third," "fourth," etc.) is solely for the purpose of differentiating between two or more items and is not meant to imply any sequence or order or importance to one item over another or any order of addition, for example.

[0014] The use of the term "or" in the claims is used to mean an inclusive "and/or" unless explicitly indicated to refer to alternatives only or unless the alternatives are mutually exclusive. For example, a condition "A or B" is satisfied by any of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present).

[0015] As used herein, any reference to "one embodiment," "an embodiment," "some embodiments," "one example," "for example," or "an example" means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearance of the phrase "in some embodiments" or "one example" in various places in the specification is not necessarily all referring to the same embodiment, for example. Further, all references to one or more embodiments or examples are to be construed as non-limiting to the claims.

[0016] Throughout this application, the term "about" is used to indicate that a value includes the inherent variation of error for a composition/apparatus/ device, the method being employed to determine the value, or the variation that exists among the study subjects. For example, but not by way of limitation, when the term "about" is utilized, the designated value may vary by plus or minus twenty percent, or fifteen percent, or twelve percent, or eleven percent, or ten percent, or nine percent, or eight percent, or seven percent, or six percent, or five percent, or four percent, or three percent, or two percent, or one percent from the specified value, as such variations are appropriate to perform the disclosed methods and as understood by persons having ordinary skill in the art.

[0017] As used in this specification and claim(s), the words "comprising" (and any form of comprising, such as "comprise" and "comprises"), "having" (and any form of having, such as "have" and "has"), "including" (and any form of including, such as "includes" and "include"), or "containing" (and any form of containing, such as "contains" and "contain") are inclusive or open-ended and do not exclude additional, unrecited elements or method steps.

[0018] The term "or combinations thereof" as used herein refers to all permutations and combinations of the listed items preceding the term. For example, "A, B, C, or combinations thereof" is intended to include at least one of: A, B, C, AB, AC, BC, or ABC, and if order is important in a particular context, also BA, CA, CB, CBA, BCA, ACB, BAC, or CAB. Continuing with this example, expressly included are combinations that contain repeats of one or more item or term, such as BB, AAA, AAB, BBC, AAABCCCC, CBBAAA, CABABB, and so forth. The skilled artisan will understand that typically there is no limit on the number of items or terms in any combination, unless otherwise apparent from the context.

[0019] As used herein, the term "substantially" means that the subsequently described event or circumstance completely occurs or that the subsequently described event or circumstance occurs to a great extent or degree. For example, when associated with a particular event or circumstance, the term "substantially" means that the subsequently described event or circumstance occurs at least 80% of the time, or at least 85% of the time, or at least 90% of the time, or at least 95% of the time. For example, the term "substantially adjacent" may mean that two items are 100% adjacent to one another, or that the two items are within close proximity to one another but not 100% adjacent to one another, or that a portion of one of the two items is not 100% adjacent to the other item but is within close proximity to the other item.

[0020] As used herein, the term "added" is understood to refer to an element that is introduced into a composition and not to the element as it may naturally inherently exist in a composition.

[0021] When the content of one ingredient is expressed as "w/w," this expression indicates weight percentage (the ratio or percentage of one substance out of the total) of the ingredient in the composition.

[0022] The term "polypeptide" as used herein will be understood to refer to a polymer of amino acids. The polymer may include d-, I-, or artificial variants of amino acids. In addition, the term "polypeptide" will be understood to include peptides, proteins, and glycoproteins.

[0023] The term "polynucleotide" as used herein will be understood to refer to a polymer of two or more nucleotides. Nucleotides, as used herein, will be understood to include deoxyribose nucleotides and/or ribose nucleotides, as well as artificial variants thereof. The term polynucleotide also includes single-stranded and double-stranded molecules.

[0024] The terms "analog" or "variant" as used herein will be understood to refer to a variation of the normal or standard form or the wild-type form of molecules. For polypeptides or polynucleotides, an analog may be a variant (polymorphism), a mutant, and/or a naturally or artificially chemically modified version of the wild-type polynucleotide (including combinations of the above). Such analogs may have higher, full, intermediate, or lower activity than the normal form of the molecule, or no activity at all. Alternatively, and/or in addition thereto, for a chemical, an analog may be any structure that has the desired functionalities (including alterations or substitutions in the core moiety), even if comprised of different atoms or isomeric arrangements.

[0025] As used herein, the phrases "associated with" and "coupled to" include both direct association/binding of two moieties to one another as well as indirect association/binding of two moieties to one another. Non-limiting examples of associations/couplings include covalent binding of one moiety to another moiety either by a direct bond or through a spacer group, non-covalent binding of one moiety to another moiety either directly or by means of specific binding pair members bound to the moieties, incorporation of one moiety into another moiety such as by dissolving one moiety in another moiety or by synthesis, and coating one moiety on another moiety, for example.

[0026] As used herein, "substantially pure" means an object species is the predominant species present (i.e., on a molar basis it is more abundant than any other individual species in the composition), and preferably a substantially purified fraction is a composition wherein the object species comprises at least about 50 percent (on a molar basis) of all macromolecular species present. Generally, a substantially pure composition will comprise more than about 80 percent of all macromolecular species present in the composition, more preferably more than about 85%, 90%, 95%, and 99%. Most preferably, the object species is purified to essential homogeneity (contaminant species cannot be detected in the composition by conventional detection methods) wherein the composition consists essentially of a single macromolecular species.

[0027] The term "pharmaceutically acceptable" refers to compounds and compositions which are suitable for administration to humans and/or animals without undue adverse side effects such as (but not limited to) toxicity, irritation, and/or allergic response commensurate with a reasonable benefit/risk ratio.

[0028] The term "patient" as used herein includes human and veterinary subjects. "Mammal" for purposes of treatment refers to any animal classified as a mammal, including (but not limited to) humans, domestic and farm animals, nonhuman primates, and any other animal that has mammary tissue.

[0029] The term "treatment" refers to both therapeutic treatment and prophylactic or preventative measures. Those in need of treatment include, but are not limited to, individuals already having a particular condition/disease/infection as well as individuals who are at risk of acquiring a particular condition/disease/infection (e.g., those needing prophylactic/preventative measures). The term "treating" refers to administering an agent to a subject/patient for therapeutic and/or prophylactic/preventative purposes.

[0030] A "therapeutic composition" or "pharmaceutical composition" refers to an agent that may be administered in vivo to bring about a therapeutic and/or prophylactic/preventative effect.

[0031] Administering a therapeutically effective amount or prophylactica lly effective amount is intended to provide a therapeutic benefit in the treatment, prevention, and/or management of a disease, condition, and/or infection. The specific amount that is therapeutically effective can be readily determined by the ordinary medical practitioner, and can vary depending on factors known in the art, such as (but not limited to) the type of condition/disease/infection, the patient's history and age, the stage of the condition/disease/infection, and the co-administration of other agents.

[0032] The term "effective amount" refers to an amount of a biologically active molecule or sufficient to exhibit a detectable therapeutic effect without undue adverse side effects (such as (but not limited to) toxicity, irritation, and allergic response) commensurate with a reasonable benefit/risk ratio when used in the manner of the inventive concept(s). The therapeutic effect may include, for example but not by way of limitation, preventing, inhibiting, or reducing the occurrence of infection by or growth of microbes and/or opportunistic infections. The effective amount for a subject will depend upon the type of subject, the subject's size and health, the nature and severity of the condition/disease/infection to be treated, the method of administration, the duration of treatment, the nature of concurrent therapy (if any), the specific formulations employed, and the like. Thus, it is not possible to specify an exact effective amount in advance. However, the effective amount for a given situation can be determined by one of ordinary skill in the art using routine experimentation based on the information provided herein.

[0033] As used herein, the term "concurrent therapy" is used interchangeably with the terms "combination therapy" and "adjunct therapy," and will be understood to mean that the patient in need of treatment is treated or given another drug for the disease/infection in conjunction with the compositions of the present disclosure. This concurrent therapy can be sequential therapy, where the patient is treated first with one composition and then the other composition, or the two compositions are given simultaneously.

[0034] The terms "administration" and "administering," as used herein, will be understood to include all routes of administration known in the art. In addition, the compositions of the present disclosure (and/or the methods of administration of same) may be designed to provide delayed, controlled, or sustained release using formulation techniques which are well known in the art.

[0035] Turning now to the inventive concept(s), certain non-limiting embodiments of the present disclosure are directed to a composition having at least one anti-viral activity.

In addition, the anti-viral active ingredient(s) may be mixed with excipients which are pharmaceutically acceptable and compatible with the anti-viral active ingredient(s). Suitable excipients include, for example but not by way of limitation, water, saline, dextrose, glycerol, ethanol, and the like, or any combination thereof. [0060] The preparation of compositions for use as topical compositions is well known to those of skill in the art. Typically, such compositions are prepared either as liquid solutions, suspensions, creams, gels, ointments, lotions, serums, foams, pastes, balms, sprays, etc.; however, other gaseous, liquid, semi-solid, or solid forms are also contemplated. In addition, the compositions disclosed or otherwise contemplated herein may contain minor amounts of auxiliary substances, such as (but not limited to) wetting or agents, pH buffering agents, thickeners, diluents, dispersing aids, binders, scents/odorants, or the like, as well as any combination thereof. The compositions of the present disclosure may contain any such additional ingredients so as to provide the composition in a form suitable for administration.

[0061] The compositions of the present disclosure may be administered by any of the many suitable means described herein and/or which are well known to those of skill in the art, including but not limited to: topical, transdermal, or intradermal administration; as eye drops, sprays, etc.; and the like. In addition, one or more than one route of administration can be employed, either simultaneously or partially or wholly sequentially.

[0062] The compositions may be administered in conjunction with other compositions constructed in accordance with the present disclosure and/or other treatment modalities. In some embodiments, such additional treatment modalities may include (but are not limited to) various substances that have anti-inflammatory, antiitching, and/or wound healing properties. When multiple compositions are to be administered together, the compositions may be combined in a single composition or administered simultaneously or separately.

[0063] The compositions of the present disclosure possess multiple characteristics.

[0064] Yet further non-limiting embodiments of the present disclosure are directed to a method of producing one or more of any of the compositions described or otherwise contemplated herein. In one non-limiting embodiment of the method, one or more anti-viral active ingredients is mixed with one or more skin penetrants (and one or more milk oligosaccharides, if present) to produce the compositions described or otherwise contemplated herein. In another non-limiting embodiment, at least one natural anti-viral active ingredient is mixed with at least one pharmaceutical agent and one or more skin penetrants (and one or more milk oligosaccharides, if present) to produce the compositions described or otherwise contemplated herein. Particular (but non-limiting) examples of production methods are provided herein below in the Examples.

[0065] Yet further non-limiting embodiments of the present disclosure are directed to a method of using one or more of any of the compositions described or otherwise contemplated herein. In one non-limiting embodiment of the method, one or more of any of the compositions disclosed or otherwise contemplated herein is applied to at least a portion of a skin of a subject or patient. When two or more of the compositions are applied (or one or more of the compositions is applied in combination with another composition/agent), the two or more compositions may be administered simultaneously or wholly or partially sequentially.

[0066] Certain additional non-limiting embodiments of the present disclosure are directed to a method of preventing or reducing the occurrence or severity of a viral- borne infection in a subject or patient. In the method, one or more of any of the compositions disclosed or otherwise contemplated herein is applied to at least a portion of a skin of the subject/patient. [0067] In certain particular (but non-limiting) embodiments, the composition is applied to and/or in a vicinity of at least one insect bite.

[0068] Alternatively, and/or in addition thereto, the composition is applied in a vicinity of a break in the skin. For example (but not by way of limitation), application in this manner may be effective at substantially preventing or reducing the occurrence of sexually transmitted diseases (as discussed in detail elsewhere herein) or other types of skin infections caused by viruses.

[0069] In certain particular (but non-limiting) embodiments, the application of the composition reduces the occurrence of post-bite (or post-break) secondary infections.

[0070] The amount of composition that is administered to a subject in need thereof varies according to many factors, e.g., the age, weight, overall health, gender, genetic history, history of allergies, prior infection, stage of current infection, etc. of the subject. The compositions can be administered in a manner compatible with the dosage formulation and in such amounts as will be therapeutically effective. Precise amounts of active ingredient(s) required to be administered depend on the judgment of the practitioner and may be monitored on a patient-by-patient basis. The dosage may also depend, without limitation, on the route of administration, the patient's state of health and weight, and the nature of the formulation.

[0071] Subjects who may be treated using the formulations of compositions disclosed or otherwise contemplated herein are usually mammals and are frequently humans. However, this need not always be the case. Veterinary uses of the compositions and methods disclosed or otherwise contemplated herein are also contemplated, e.g., for companion pets, ruminants, or other animals that are of commercial value e.g., as a food source, or for any other animal, etc. For example (but not by way of limitation), dogs, cats, and horses are particularly susceptible to Arthropod-borne illnesses, and thus can particularly benefit from the compositions and methods of the present disclosure.

EXAMPLES [0072] Examples are provided hereinbelow. However, the present disclosure is to be understood to not be limited in its application to the specific experimentation, results, and laboratory procedures disclosed herein. Rather, the Examples are simply provided as one of various embodiments and are meant to be exemplary, not exhaustive.

Example 1

[0073] Production and screening of compositions comprising at least one anti-viral active ingredient and at least one skin penetrant

[0074] In this Example, compositions are disclosed that include one or more broad spectrum anti-viral actives, wherein the compositions have multiple targeted applications to health, hygiene, and nutrition. In one non-limiting embodiment, the composition is a post-mosquito bite, fast penetrating skin cream, gel, ointment, lotion, serum, foam, paste, balm, spray, etc., that delivers active anti-viral ingredient(s) to the dermal layers of a subject's skin, where the anti-viral ingredient(s) inhibits viral activity (such as, but not limited to, entry of virus into host cell and/or viral replication, etc.) without affecting wound healing.

[0075] The compositions of the present disclosure are developed to provide broadly applicable, cost-effective interventions for mosquito- and tick-borne infections, in contrast to the existing non-effective repellents and post-bite creams that simply possess anti-itching and/or wound healing properties, but have no effect on preventing transmission of the infection to the blood stream.

[0076] The anti-viral active ingredient(s) are GRAS and substantially non-toxic, and as such, will be safe to use on the wound/bite area. In addition, the anti-viral active ingredient(s) can effectively protect from mosquito-borne viruses based on: (i) broad spectrum anti-viral activity; (ii) high and quick skin penetrability to act on inactivating the virus within a short window of time (and potentially in the skin layers before the virus reaches the blood stream and spreads through the body); (iii) stimulation of skin macrophages for enhancing viral clearance; and/or (iv) broad range anti-microbial effects to prevent post-bite secondary infections. Further, the compositions may have soothing, anti-itching, anti-inflammatory, and/or wound healing properties.

[0077] The compositions may be utilized prior to or after exposure to the Arthropods. As such, the compositions provide mechanisms to manage both infection and disease manifestation.

[0078] In certain particular (but non-limiting) embodiments, the compositions provide a treatment for post-vector bites to stop the spread of virus into the blood stream. The composition uses, in one non-limiting embodiment, at least one anti-viral active ingredient that is GRAS and substantially safe on the skin beneficial microbiome, while substantially preventing or reducing the occurrence or severity of secondary bacterial/fungal infections (due to, for example (but not by way of limitation) scratching).

[0079] The virucidal efficacy (ICso) and cytotoxicity of the anti-viral actives of this Example are studied in vitro and in a 3D skin model.

[0080] Screening of the anti-viral actives involves the following protocol. At least six Arboviruses are procured (Dengue, Chikungunya, Zika, West Nile, Japanese encephalitis, and Yellow Fever viruses) and grown under Institutional Biosafety Committee (IBC) and BSL-3 protocols. Required cell lines are obtained from ATCC. Virus titration techniques are standardized. The cytotoxicities of at least twelve (12) compounds/substances are then tested on cell lines used to grow and test antiviral effects, as well as on primary cells isolated from blood. In addition, the antiviral effects of the twelve organic compounds are evaluated at different non-toxic concentrations on four Arboviruses in a BSL-2 laboratory (Dengue, Chikungunya, Zika, and Yellow Fever viruses), and on two Arboviruses in a BSL-3 laboratory (West Nile and Japanese Encephalitis viruses). The results are then analyzed to identify anti-viral active ingredients that are safe/GRAS and that exhibit anti-viral activity against at least one of the six viruses tested. The top performing anti-viral active ingredient(s) formulations are then tested on a 3D skin culture model to determine skin permeability and stimulation of skin macrophages for virus clearance. [0081] The formulations being tested include anti-viral active ingredients singularly and in combination with one or more other anti-viral active ingredients, and these ingredient(s) are also tested in combination with skin penetrant(s) and HMO(s), so as to identify formulations that have a synergistic effect and that can work against a broad panel of viruses. Formulations of active(s) at differing concentrations are also tested, both alone and in combination with skin penetrant(s), so as to determine optimal concentrations thereof along with rapid release thereof to allow for clearance of the virus before it enters the blood stream.

[0082] The formulations tested are also analyzed to determine that they are safe on the skin microbiome (i.e., high MIC for beneficial microbiome). As disclosed in Ruiz- Lopez (Front. Microbiol. (09 Dec 2020) 11:573371), the microbiota is able to influence host health and individual fitness through multiple pathways, such as nutrient synthesis, immune system development, and even behavioral processes. Thus, changes in the microbiome's composition can lead to physiological changes that can increase the risk of opportunistic pathogen infection or impair the immune response.

[0083] In addition, the formulations tested are also analyzed to determine if they are capable of preventing secondary bacterial/fungal skin infections (such as, but not limited to, due to scratching; i.e., low MIC on pathogenic strains). The Minimum Inhibitory Concentration (MIC) is determined by culturing the microorganism in liquid media or on plates of solid growth medium. A lower MIC value indicates that less drug is required for inhibiting growth of the organism; therefore, drugs with lower MIC scores are more effective antimicrobial agents.

Example 2

[0084] Analysis of Compositions where the anti-viral active ingredient(s) includes at least one natural ingredient, such as (but not limited to) a plant-based anti-viral ingredient

[0085] Several natural products, especially from plants such as Tea tree oil, Eucalyptus oils, Essential oils, Cyclodextrins (i.e., naturally occurring modified sugar molecules) are known to have virucidal properties.

[0086] Oleuropein contained in olive leaves is a powerful inhibitor to a wide range of viruses that blocks the production of enzymes for virus replication.

[0087] Quinoids in Pau d'arco inhibit virus replications by damaging viral DNA/ RNA.

[0088] Methanol extract of roots of Ampelocissus tomentosa have a low ICso (7.79 pg/ml) for CHIKV and higher CCso or cytotoxic 50% effector dose of 36.6 pg/ml. In addition, these extracts have high other antimicrobial inhibitory ability, showing 100% relative inhibition for E. coll, P. aeruginosa, S. aureus, and L. innocua; 93% relative inhibition for 5. sonnei; 62% relative inhibition for C. albicans; and 14% relative inhibition for 5. enterica. In addition, the MIC for 5. aureus and P. aeruginosa is below the CCso level.

[0089] The natural flavone baicalein exerts potent activity against DENV, JEV, and CHIKV adsorption to the host and post-entry viral replication. The complexity of chemical structures that flavonoids offer presents potential broad-spectrum antiviral activities that can target various enzymes to disrupt the viral replication cycle.

[0090] Another natural compound 6-deoxyglucose-diphyllin (DGP), also known as Patentiflorin A, is a naphthalene-derived bioactive phytoconstituent molecule from a medicinal plant Justicia gendarussa. It can be chemically synthesized and exhibits broadspectrum antiviral activity that potently blocks infection by Zika, Dengue, Yellow Fever, Tickborne Encephalitis, Japanese Encephalitis, West Nile, and Ebola viruses. DGP has been shown to be highly effective against Zika virus infection in vivo at very low concentrations (nM range) with undetected toxicity, and has reached into clinics as Diphyllin. [0091] Thus, plant products utilized as the anti-viral active ingredient(s) in accordance with the present disclosure are natural, substantially non-toxic, and mild to human skin, with no allergy or health risks aroused by skin contact. In addition, plant products are typically readily available and have very few or no side effects. Further, the resources of most natural viral inhibitors identified above have been well documented with easy extraction processes.

[0092] In addition to the various anti-viral active ingredients described in the Examples, each of the compositions of the present disclosure also contain at least one skin penetrant in the formulations thereof. These ingredients have good skin penetrability and include (for example, but not by way of limitation) emulsifiers that form micelles which can surround and encapsulate the "active" ingredients of the compositions. For example, emulsion penetration can be enhanced by reducing the particle size of the emulsion.

[0093] Particular (but non-limiting) examples of skin penetrants utilized in the compositions of the present disclosure include an emulsion system, a microemulsion system, a nanoemulsion system, an emulsifier (such as, but not limited to, phosphatidylcholine, propylene glycol, polyethylene glycol, diethylene glycol monoethyl ether, oleic acid and laurocapram, a ceramide, a phospholipid, an essential fatty acid (EFA), and the like, as well as any combinations thereof), a surfactant (such as, but not limited to, sodium lauryl sulfate (SLS), an oleic acid, a lauryl ether, a polysorbate, a cetyl alcohol, sorbitan stearate, a stearyl alcohol, a cetostearyl ether, a cetostearyl alcohol), Phytosome, propylene glycol, allantoin, panthenol, dexpanthenol, paraffin, soap nut surfactant, and the like, as well as combinations thereof.

[0094] In a particular (but non-limiting) example, micro-emulsions and nanoemulsions of phosphatidylcholine and propylene glycol are excellent penetration enhancers and are used to help shuttle soluble active ingredients through the lipid top layers of the skin into the lower layers. Similarly, Phytosome, a complex of a natural active ingredient and a phospholipid (mostly lecithin), is claimed to increase absorption of "conventional herbal extracts" or isolated active principles both topically as well as orally.

[0095] Sodium lauryl sulfate (SLS), an anionic surfactant, possesses skin penetration enhancer properties and enhances penetration into the skin by increasing the fluidity of epidermal lipids. The increase in lipid fluidity below the applied site may allow SLS to diffuse in all directions including the radial path. SLS thus increases intraepidermal drug delivery when utilized in the formulations of the present disclosure.

Example 3

[0096] Analysis of Compositions where the anti-viral active ingredient(s) includes at least one pharmaceutical agent

[0097] In this Example, anti-viral compositions of Example 1 and similar to those described in Example 2 are provided, except that where Example 2 utilizes natural and/or plant-based anti-viral active ingredient(s), this Example utilizes one or more pharmaceutical agents, either alone or in combination with one or more plant-based anti-viral active ingredients (or other natural anti-viral ingredient(s)).

[0098] Recently ALDARA® (Imiquimod, Graceway Pharmaceuticals, LLC, Bristol, TN), which was originally approved for treating genital warts, has been repurposed to stimulate skin resident macrophages. This was demonstrated to effectively clear viruses from skin for up to five hours in experimental animals with post mosquito bite situation (Bryden et al., Sc/. Transl. Med. (2020) 12, eeax2421).

[0099] WO 2017/029298 discloses a topical antiviral composition for treating cold sores. The topical antiviral composition comprises antiviral active ingredient or analogues or derivatives thereof in combination with antiherpes oils and an acid active ingredient.

[0100] However, no compositions for use post-arthropod bite and containing antiviral pharmaceutical active ingredient(s), skin penetrant(s), and/or HMOs have been described prior to the present disclosure.

[0101] Non-limiting examples of pharmaceutical agents utilized in formulations of the compositions of the present disclosure include acyclovir, valacyclovir, famciclovir, ganciclovir, penciclovir, docosanol, edoxudine, ibacitabine, idoxuridine, imiquimod, inosine, muramidase, podophyllotoxin, sinecatechins, tromantadine, an analogue or derivative of any of the above, and any combinations of two or more of any of the above.

Example 4

[0102] Analysis of anti-viral active ingredient-containing compositions that further include at least one milk oligosaccharide

[0103] In this Example, compositions are prepared that include at least one anti-viral active ingredient, at least one skin penetrant, and at least one milk oligosaccharide. The milk oligosaccharide(s) serves to enhance viral clearance by (for example, but not by way of limitation) recruiting skin macrophages, as described in greater detail herein below.

[0104] Interestingly, some milk components/human milk oligosaccharides (HMO), such as (but not limited to) sialyl(a2,3)lactose and lacto-N-fucopentaose III, were reported to increase TLR signaling (YingYing He et al., Adv Nutr. (15 Jan 2016) 7(l):102- 11). Toll like receptors (TLRs) play crucial roles in the innate immune system by recognizing pathogen-associated molecular patterns derived from various microbes.

[0105] After a mosquito bite, a wound healing repair mechanism begins; however, the skin does not prepare itself to respond to viral attack, and so the mosquito-borne viruses entering the skin through a bite are able to reach the bloodstream and lymphatic system to spread throughout the body. Considering the short window of operation, a broad-spectrum antiviral agent combined with suitable milk components/HMOs can quickly act on the virus released by the mosquito in the dermis/deep layers of the skin. This is achieved through combined activities of skin macrophages recruited by HMOs and direct virucidal action of anti-viral actives.

[0106] The combination of the anti-viral active ingredient(s), skin penetrants, and milk oligosaccharides/HMOs can effectively protect from mosquito-borne viruses based on: (i) broad spectrum anti-viral activity; (ii) H MO-mediated stimulation of skin macrophages that enhances virus clearance; (iii) additional anti-bacterial/anti-fungal activities that prevents post-bite secondary infections; and (iv) rapid skin penetrability to act on virus inactivation in a short window of time.

[0107] Thus, the compositions of this Example include the presence of milk oligosaccharides/HMOS that further enhance the efficacy and direct virucidal action of one or more GRAS anti-viral actives, wherein the compositions also provide additional benefits such as (but not limited to) skin repair/wound healing, anti-bacterial activity, and anti-fungal activity.
