Abstract
Description
[0001] Cross-reference to related applications
[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 324,087, filed Mar. 27, 2022, and U.S. Provisional Patent Application No. 63 / 398,038, filed Aug. 15, 2022. The entire contents of the above applications are incorporated herein by reference. Technical Field
[0003] The present invention generally relates to methods and compounds for treating viral infections, particularly avermectin-based methods and compounds for treating infections by coronaviridae SARS-CoV-2, flaviviridae dengue and Zika, and togaviridae chikungunya virus. Background Art
[0004] Human coronaviruses were first discovered in the mid-1960s and are common viruses that most people are infected with at some point in their lives, typically causing mild to moderate upper respiratory and gastrointestinal diseases. A novel coronavirus called "Middle East Respiratory Syndrome Coronavirus" (MERS-CoV or MERS) was first reported in Saudi Arabia in 2012 and spread to several other countries. SARS-CoV, the coronavirus that causes Severe Acute Respiratory Syndrome (SARS), caused a global outbreak in 2002 and 2003.
[0005] Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is a strain of coronavirus that causes COVID-19 (Coronavirus Disease 2019), a respiratory disease and the pathogen responsible for the ongoing COVID-19 pandemic. The World Health Organization declared the outbreak a Public Health Emergency of International Concern on Jan. 30, 2020, and a pandemic on Mar. 11, 2020. SARS-CoV-2 is a positive-sense single-stranded RNA virus that is infectious in humans.
[0006] As of December 2021, the number of cases continued to climb due to multiple factors, including new COVID-19 variants. As of Dec. 28, 2021, 282,790,822 people had been confirmed infected globally. As of Apr. 14, 2022, the global confirmed cases exceeded 500 million. Most cases are unconfirmed, and the Institute for Health Metrics and Evaluation estimated the true number of cases in early 2022 to be in the billions.
[0007] According to the World Health Organization (WHO), the increasing awareness of Aedes - transmitted viruses in recent years, especially chikungunya virus, Zika virus, and dengue virus, has become a global concern. Unfortunately, due to the lack of arbovirus disease surveillance and a comprehensive understanding of arboviral diseases, these diseases are hidden behind malaria. Underestimating arboviral diseases can lead to misdiagnosis and unnecessary medical costs, especially in febrile illnesses suspected of being malaria. Approximately 3.9 billion people from 120 different regions seem to be at risk of these three major arboviruses. Summary of the Invention
[0008] Technical Problem
[0009] Some compounds show antiviral activity in vitro, and some of them are used in disease treatment, but the treatment effect is sometimes insufficient. There are difficulties in increasing the bioavailability and permeability of drugs.
[0010] Ivermectin is a drug used to treat parasitic infections. In vitro, ivermectin has antiviral effects against several different RNA and DNA viruses. In vitro, ivermectin can inhibit the replication of RNA viruses such as Zika virus, dengue virus, yellow fever virus, West Nile virus, Hendra virus, Newcastle disease virus, Venezuelan equine encephalitis virus, chikungunya virus, forest virus, Sindbis virus, avian influenza A virus, porcine reproductive and respiratory syndrome virus, human immunodeficiency virus type 1, and severe acute respiratory syndrome coronavirus 2. In vitro, ivermectin can inhibit the replication of DNA viruses such as equine herpesvirus type 1, BK polyomavirus, pseudorabies virus, porcine circovirus type 2, and bovine herpesvirus type 1. In vitro, ivermectin can inhibit the replication of severe acute respiratory syndrome coronavirus 2 at concentrations of EC50 2.4 μM and EC90 5 μM.
[0011] The antiviral effect of ivermectin has been recorded:
[0012]
[0013]
[0014] The degree of inhibition of virus replication by ivermectin directly depends on the concentration of ivermectin in the cells. Once the concentration of ivermectin in the cells reaches the threshold concentration, each subsequent increase in the concentration of ivermectin in the body tissues will increase the inhibitory effect. Generally, the concentration of ivermectin in the body tissues is higher than that in the plasma. For example, the plasma - to - lung ratio of cattle is about 2.67, and that of humans is about 3.0.
[0015] Even a high dose of ivermectin in the form of a standard tablet at 600 μg / kg per day can only produce a pulmonary Cmax of 0.4 - 0.9 μM over 5 days, which is far below the concentration required to inhibit viral replication and cannot provide the concentration of ivermectin in body tissues necessary for effective inhibition of viral replication.

These isotopically labeled compounds are useful in metabolic studies, reaction kinetics studies, detection, or imaging techniques such as positron emission tomography (PET) or single photon emission computed tomography (SPECT), including tissue distribution analysis of drugs or substrates, or in the radiotherapy of patients. The present disclosure also includes compounds of FORMULA I, wherein 1 to n hydrogens attached to carbon atoms are replaced by deuterium, where n is the number of hydrogens in the molecule. These compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any FORMULA I compound when administered to mammals, particularly humans.
[0107] III. Key methods and concepts of the invention.
[0108] The solid dispersions of the present invention can be defined as the solid-state dispersion of one or more active ingredients (API) in an inert carrier or matrix (HOST) prepared by melting / fusion method, solvent method, melt-solvent method, mechanochemical treatment and other methods. The API drugs are hydrophobic in nature, while the matrix (HOST) is hydrophilic. The solid dispersions of the present invention can be molecular dispersions, simple eutectic mixtures, solid solutions, glass solutions and glass suspensions, mechanochemically obtained solid dispersions (including solid dispersions in the form of micro-machine complexes in which solid-phase fusion, mechanical synthesis, and mechanical activation processes have occurred), amorphous precipitates in crystal carriers, compound or complex formations. The solid dispersions of the present invention can be first-generation solid dispersions; second-generation solid dispersions; third-generation solid dispersions; fourth-generation solid dispersions. The solid dispersions of the present invention can be classified according to the physical state and molecular arrangement form of the API and the carrier: C-C type, C-A type, A-C type, A-A type, M-C type, M-A type.
[0109] Table 1. Classification according to the physical state and molecular arrangement of API and carrier (HOST)
[0110]
[0111]
[0112] Many analytical and instrumental techniques are used to characterize solid dispersions. The techniques used for characterization can be thermal analysis, spectroscopy, microscopy, microthermal analysis, macroscopic techniques, etc. A mere mixture of substances without treating the API and the carrier (HOST) will not yield the results brought about by solid dispersion. Solid dispersions are not mixtures in which synergists amplify each other's effects. Solid dispersions are not a kind of nanoparticles.
[0113] The non-covalent complexes of the present invention are molecular aggregates that have specific properties different from the environment as a whole, and their internal structure and form are determined by non-covalent interactions of atoms. This makes the non-covalent system different from molecular systems whose structures are mainly determined by covalent interactions. Non-covalent complexes are molecular complexes of two or more cations, anions or neutral molecules held together in a single system by hydrogen bonds, van der Waals interactions, donor-acceptor interactions, π-π interactions, ionic interactions, and hydrophobic interactions. Non-covalent complexes have the ability to form different structures while the chemical composition of the system remains unchanged. The non-covalent complexes of the present invention are composed of at least two different components, usually a matrix (HOST, host substance, "host", "host substance", "carrier", etc.) and a therapeutic agent (API, GUEST, active pharmaceutical ingredient, drug, guest, "guest drug", "guest drug compound", "guest substance", etc.). Many analytical and instrumental techniques are used to characterize non-covalent complexes (such as spectroscopy).
[0114] A treatment method is provided, which comprises administering a therapeutically effective amount of a solid dispersion to a patient in need (human, mammal, animal or bird), including: contacting an API and a matrix "HOST substance" under conditions sufficient to form a solid dispersion to form a solid dispersion; and (optionally) dissolving the solid dispersion in a solvent to form a liquid-dissolved non-covalent complex (forming a solution, gel, colloid, sol, suspension, etc.) under conditions sufficient to form a liquid-dissolved non-covalent complex.
[0115] On the other hand, a treatment method is provided, which comprises administering a therapeutically effective amount of a solid dispersion or a non-covalent complex to a patient in need (human, mammal, animal or bird), wherein the "carrier substance" (HOST substance) molecules of the solid dispersion or the non-covalent complex interact with the biological membrane of the organism, thereby improving the transfer of API molecules and ions through such a biological membrane; the permeability of the API in the form of a non-covalent complex is improved. Therefore, the scope of the present invention includes solid dispersions and non-covalent complexes having special permeability characteristics; solid dispersions and non-covalent complexes having high permeability.
[0116] On the other hand, a method for treating a viral disease is provided, which comprises administering a therapeutically effective amount of a solid dispersion or a non-covalent complex to a patient in need (human, mammal, animal or bird), wherein the solid dispersion or the non-covalent complex of the API has a higher bioavailability than the API itself.
[0117] On the other hand, a method for treating a viral disease is provided, which comprises administering a therapeutically effective amount of a solid dispersion or a non-covalent complex to a patient in need (human, mammal, animal or bird), wherein the solid dispersion or the non-covalent complex of the API has lower toxicity and cytotoxicity than the API itself.
[0118] In another aspect, a method for treating a viral disease is provided by administering a therapeutically effective amount of a solid dispersion or a non-covalent complex to a patient or mammal or animal or bird in need, wherein the solid dispersion or the non-covalent complex of the API has pharmacokinetic parameters different from those of the API itself.
[0119] In another aspect, a method for preparing or manufacturing the solid dispersion or the non-covalent complex of the present invention is provided.
[0120] The method for obtaining the solid dispersion of the present invention includes:
[0121] 1) Solvent evaporation and cryogenic methods;
[0122] 2) Melt method and hot-stage extrusion method;
[0123] 3) Mechanochemical methods (but not limited to other methods).
[0124] The particle size of the solid dispersion may vary depending on the equipment (such as nozzle size), equipment operating parameters, and the degree of grinding of the finished product. The typical particle size is 0.5 - 1000 microns, but it can exceed 1000 microns, and the obtained solid dispersion can also be ground to submicron size after being obtained.
[0125] The solvent evaporation method involves dissolving the API and the carrier (HOST substance) in a volatile solvent and then evaporating the solvent. In this method, thermal decomposition of the API or the carrier can be prevented because the evaporation of the organic solvent occurs at low temperatures. The differences in the solvent evaporation process are related to the solvent evaporation procedures, which typically include vacuum drying, heating the mixture on a hot plate, slowly evaporating the solvent at low temperature, using a rotary evaporator, nitrogen gas flow, spray drying, freeze drying, using supercritical fluids (SCF), and other types of solvent evaporation.
[0126] The melting method involves melting the API in the carrier (HOST substance) and then cooling and grinding the resulting product. During the melting process, the molecular mobility of the carrier is high enough to change the incorporation of the drug. A common modification of the melting stage is to suspend the API in the pre-melted carrier instead of having both the drug and the carrier in the molten state, thereby reducing the process temperature. To cool and solidify the molten mixture, various processes are used, such as stirring in an ice bath, spreading a thin layer on stainless steel and blowing cold air, curing on a petri dish at room temperature in a desiccator, spreading on dry ice, immersing in liquid nitrogen or storing in a desiccator, and other types of cooling. After cooling, the mixture must be ground for easy handling. However, the use of high temperatures and the possible degradation of some drugs during melting may be a limitation of this method. The possible incomplete miscibility between the drug and the carrier due to the high viscosity of the polymer carrier in the molten state is another limitation of this process. To avoid the limitations of the melting method, various modifications have been made to the original method, such as hot stage extrusion, Meltrex, melt aggregation, etc.
[0127] The mechanochemical method for obtaining solid dispersions involves mechanical processing under conditions of high-intensity mechanical treatment (e.g., in a planetary or other type of mill), where processes of solid-phase fusion, mechanical synthesis, and mechanical activation between components occur, including the formation of microcomposites, where the processes of mechanochemical solid-phase fusion / melting, mechanical synthesis, and mechanical activation of the API with the HOST substance occur. When the components are mixed, reactions occur in the solid phase, forming a product with a high contact surface and an extremely high concentration of various defects. An interfacial surface required for physical-chemical interactions is formed. Under these conditions, the characteristic time of mass transfer between the reagents is reduced for physical-chemical reactions to occur. While comminuting and forming the solid dispersion obtained mechanochemically, additional structural defects are generated in the mixture components. In a macroscopic approximation, the activation energy barrier for chemical interactions is reduced. Generally, the longer the mechanical processing time, the higher the bioavailability and permeability of the resulting solid dispersion, while the particle size remains almost unchanged.
[0128] At the initial stage of mechanochemical processing, the initial collisions of powder particles with the spheres result in plastic deformation and flattening of the particles. The continuous plastic deformation is accompanied by an increase in the ratio of the particle surface area to its volume. During the deformation of the particles, the pure inner layer of the API is opened and comes into close contact with the pure layer of another component, leading to a welding process. The accompanying plastic deformation hardening reaches a critical value, and the formed object is broken. Then, the three processes of plastic deformation, welding, and fracture of the processed particles are repeatedly parallel many times. During this process, the material acquires a layered, distorted structure. At the end of the initial fusion stage, a hybrid heterogeneous system called a mechanical composite is formed. The mechanical composite has a morphologically metastable structure with a high density of phase interfaces between the initial components, providing a developed contact surface and a high concentration of defects due to a large number of atoms on the surface and near the surface layer. Such a system has a large amount of stored energy, which, together with the extremely large contact surface between the components, provides a high reactivity of the system. At the same time, although the contact surface of the reagents in the matrix is almost perfect, a large number of inclusions of the more brittle component in contact with the plastic reagent in the volume of the mechanical composite are still visible.
[0129] The mechanochemical processing method leads to the same results as other methods but excludes the use of toxic solvents or the process of thermal degradation of the API.
[0130] In the present invention, solid dispersions with high bioavailability and non-covalent complexes with high bioavailability are obtained and used. High bioavailability for the solid dispersions and non-covalent complexes means at least one of the following:
[0131] 1) The absolute or relative bioavailability of the solid dispersion or non-covalent complex of the API is higher than that of the API itself;
[0132] 2) The concentration of the API and / or its metabolites in blood, organs or tissues, the maximum plasma concentration, pharmacokinetic parameters, etc. are higher for the solid dispersion or non-covalent complex of the API than for the API itself.
[0133] The release rate of the API molecule from the non-covalent complex may play an important role in increasing bioavailability.
[0134] Non-covalent complexes play a particularly important role in biological systems, such as the transfer of molecules and ions across biological membranes. Highly permeable solid dispersions or non-covalent complexes are obtained and used in the present invention. High permeability for the solid dispersion or non-covalent complex means at least one of the following:
[0135] 1) The transfer of the API molecule, ion, metabolite across the biological membrane / cell membrane is better for the solid dispersion or non-covalent complex of the API than for the API itself;
[0136] 2) The transfer of the API molecule, ion, metabolite across the Caco-2 cell line layer or other cell line layers (such as the intestinal epithelial cell layer, etc.) is better for the solid dispersion or non-covalent complex of the API than for the API itself;
[0137] 3) The intestinal permeability of the solid dispersion or non-covalent complex of the API is better than that of the API itself;
[0138] 4) The permeability is increased according to the method for determining permeability in the biopharmaceutics classification system.
[0139] Within the scope of the present invention, an increase in the permeability and absorption of the API in the solid dispersion or non-covalent complex is achieved through the following mechanisms (but not limited to other mechanisms for increasing permeability):
[0140] 1) Due to the interaction of the membrane with the carrier substance (HOST) molecule, blocking / reducing the activity of CYP3A4 and / or P-glycoprotein, blocking / reducing the activity of other transmembrane carrier proteins, transporters, enzymes, etc.;
[0141] 2) Due to the interaction of the carrier substance (HOST) molecule with the membrane, blocking / reducing the activity of CYP3A4 and / or P-glycoprotein, blocking / reducing the activity of other transmembrane protein transporters, transporters, enzymes, etc., this adhesion may lead to an interaction with the transporter region located outside the cell membrane and block the action of the transmembrane transporter;
[0142] 3) Due to the incorporation of the carrier substance (HOST) molecule into the membrane rather than due to adhesion, resulting in a change in the cell membrane structure;
[0143] 4) Due to the direct action of the carrier substance (HOST) molecules on the intestinal epithelial cell membrane: This may include altering the properties of the lipid bilayer, the density of cell-cell contacts, or inhibiting transmembrane proteins involved in multidrug resistance;
[0144] 5) Due to changes in the hydrophilicity and hydrophobicity of the non-covalent complex, paracellular transport of the non-covalent complex may occur;
[0145] 6) Other changes in the membrane structure and properties caused by other mechanisms contribute to increasing its permeability.
[0146] Carriers play a major role in the formulation of solid dispersions. They can be hydrophilic, hydrophobic, or swellable upon water absorption. Depending on their properties, they can be used as release retardants or release enhancers. The dissolution characteristics of drug molecules also depend on the nature of the carrier. The criteria for selecting the carrier (HOST) are as follows:
[0147] a. It should be water-soluble or swellable and soluble in various solvents.
[0148] b. It should be economical, pharmacologically inert, and non-toxic.
[0149] c. It should be heat-resistant.
[0150] d. Chemically compatible with the drug.
[0151] e. Water-soluble and water-insoluble carriers must prevent the recrystallization tendency through hydrogen bond interaction and help maintain a supersaturated state after dissolution (spring and parachute effects).
[0152] Due to their diverse pharmaceutical applications, availability, biocompatibility, non-toxicity, and chemical inertness, polymers of plant origin are used in the present invention and are more favored compared to synthetic polymers. Polysaccharides are one of the most abundant industrial raw materials and are used due to their sustainability, biosafety, and biodegradability. Natural gums are metabolic by-products of plants and come from various parts of plants such as seeds, fruits, and cut tree trunks (gummy exudates), etc.
[0153] Natural polysaccharides are biodegradable and biocompatible materials for drug delivery systems. However, these materials have some limitations, such as uncontrolled hydration rates, viscosity changes during the shelf life, and microbial contamination. Therefore, in order to overcome these problems, some improvements have been made. The improvements can be carried out by physical modification and chemical modification. Physical modification methods include the use of dry heat, microwave technology, ultraviolet light, and gamma radiation. Chemical modification includes carboxymethylation / carboxyethylation, in which the free -OH groups are replaced, thus improving the solubility of the drug in water. Generally, modifying natural carriers by heating methods results in changes in their physical properties such as viscosity, density, swelling index, water - holding capacity, flow properties, etc. Due to these property changes, the modified natural carriers obtain improved results in use. The carboxymethylation of natural carriers increases their hydrophilicity and makes them more soluble in aqueous systems.

The grinding process can produce particles, mainly sized from 1 to 1000 microns, which are powders. The grinding should be carried out to a state where the structure and properties of the ground substance are changed to increase its bioavailability and permeability and to form a highly bioavailable and highly permeable solid dispersion. The grinding should cause structural changes such as defects, increased deformation, and aggregates. During the grinding process, solid-phase fusion, mechanical synthesis, and mechanochemical activation processes must occur, including the formation of microcomposites, in which the mechanochemical solid-phase fusion, mechanical synthesis, and mechanochemical activation processes of the API substance and the host substance have occurred.

[0199] Method 2 (High-energy stress grinding or milling with solvent; mechanochemical method with solvent): The "API" and "host substance" are wetted with a solvent, the wetted material is dried, and then ground in the same manner as in Method 1. The list of solvents used is the same as the solvents listed in Method 1;
[0200] Method 3 (Media milling method): A high-shear media mill is used to prepare the solid dispersion. The grinding chamber containing the grinding media, solvent, "API", and "host substance" is rotated at a very high shear rate at a controlled temperature. The grinding media consists of glass, zirconia, highly cross-linked polystyrene resin, or other standard grinding media. The high-energy shear force is generated due to the impact of the grinding media with the "API" and "host substance". The list of solvents used is the same as the solvents listed in Method 1;
[0201] Method 4 (Kneading method): This method is based on impregnating the "host substance" with a small amount of water or a water-alcohol solution to convert it into a paste. Then the "API" is added to the above paste and kneaded for a specified period of time. Then the kneaded mixture is dried and sieved as required. At the laboratory scale, kneading can be carried out using a mortar and pestle. At the large scale, kneading can be carried out using an extruder and other machines;
[0202] Method 5 (Hot melt method, melting method, fusion method): In this method, a physical mixture of the "API" and "host substance" is directly heated until both are melted. Then the molten mixture is rapidly cooled and solidified by vigorous stirring. The final solid mass is then crushed, pulverized, and sieved. The melting method involves melting the "API" within the "host substance" and then cooling and pulverizing the resulting product. Common modifications in the melting stage include suspending the "API" in the pre-melted "host substance" instead of using the "API" and "host substance" in the molten state, thereby reducing the process temperature. To cool and solidify the molten mixture, several processes are employed, such as stirring in an ice bath, coating on a thin stainless steel layer and then passing through a cold air stream, solidifying on a petri dish at room temperature in a desiccator, coating on dry ice, immersion in liquid nitrogen, or storing in a desiccator or other cooling methods. After cooling, the mixture must be pulverized for processing. Dispersion techniques can also be used;
[0203] Method 6 (Hot melt extrusion method, hot-stage extrusion method): Hot melt extrusion is a modification of the melting method. Hot melt extrusion is essentially the same as the melting method, except that intense mixing is introduced through an extruder. Hot-stage extrusion involves extruding the pre-mixed "API" and "host substance" at the melting temperature for a short period of time at a high rotational speed. Then the resulting product is collected and ground after cooling at room temperature. By combining hot-stage extrusion with the use of carbon dioxide as a plasticizer, the processing temperature can be reduced;
[0204] Method 7 (Meltrex method): Meltrex is an improvement of the melting method. Meltrex is a patented solid dispersion manufacturing process based on a melting process. The key elements of the Meltrex technology are the use of a special twin-screw extruder and the presence of two independent hoppers, the temperatures of which can vary over a wide temperature range;
[0205] Method 8 (molten aggregation method): Molten aggregation is an improvement of the melting method. Molten aggregation allows the preparation of solid dispersions in a conventional high-shear mixer. This step is completed by adding the molten "API" containing "host substance" to the heated excipient, or adding the molten "host substance" to the heated mixture of "API" and excipient, or heating the mixture of "API", "host substance" and excipient to a temperature within or above the melting range of the "host substance". Stable solid dispersions can also be produced by the molten aggregation method in a rotary processor;
[0206] Method 9 (high-pressure homogenization): In this method, a suspension of "API" and "host substance" passes through the microporous or sub-microporous valve of a high-pressure homogenizer under pressure;
[0207] Method 10 (solvent evaporation method): In this method, "API" and "HOST substance" are dissolved in a common solvent, and then the solvent is evaporated to produce a solid solution. The basic process for preparing or manufacturing such solid dispersions includes dissolving "API" and the polymer "host substance" in a common solvent or solvent mixture (the list of solvents used is the same as the solvents in Method 1). Usually, the resulting film is crushed and / or ground. A partially suspended rather than dissolved "host substance" can also be used. Solvent evaporation procedures usually include vacuum drying, heating the mixture on a hot plate, slowly evaporating the solvent at a low temperature, using a rotary evaporator, a nitrogen stream or other drying procedures;
[0208] Method 11 (spin coating film method): The spin coating film method is a modified version of the solvent evaporation method, which includes dissolving "API" and "HOST substance" in a common solvent, and then dropping it on a clean substrate rotating at a high speed. The solvent evaporates during rotation;
[0209] Method 12 (spray drying method): Spray drying is a modified version of the solvent evaporation method. The process includes dissolving or suspending "API" and "host substance", and then spraying it into a heated gas stream to remove the solvent;
[0210] Method 13 (Supercritical Fluid (SCF) Process): The supercritical fluid process is a modified version of the solvent evaporation method. In this method, the "API" particles are dissolved in an SCF (usually carbon dioxide). Several SCF processing methods can be used to address individual aspects, such as the compressed antisolvent process (PCA), SCF solution enhanced dispersion (SEDS), supercritical antisolvent process (SAS), rapid expansion of supercritical solutions (RESS), gas antisolvent recrystallization (GAS), and aerosol supercritical extraction system (ASES). In the modification of this method, the technique involves dissolving the "API" and "HOST substance" in a common solvent and introducing them simultaneously with CO2 through a nozzle into a particle formation vessel. When the solution is sprayed, the solvent is rapidly extracted by the SCF, causing solid dispersion particles to precipitate on the walls and bottom of the vessel;
[0211] Method 14 (Cryogenic Technology): The cryogenic method is a method of dissolving the "API" and "HOST substance" in a common solvent prior to a cryogenic solvent evaporation procedure. The common solvent can be the same as in the solvent evaporation method. The solution can be frozen after injection. The injection device can be a capillary, rotary, pneumatic, ultrasonic nozzle, or other type of injection device. The position of the nozzle can be above or below the cryogenic liquid surface. The composition of the cryogenic liquid can be hydrofluoroalkane, fluorocarbon, N2, Ar, O2, organic solvent, or other types of cryogenic liquids. After cryogenic treatment, dry powder can be obtained through various drying processes such as spray freeze-drying, atmospheric freeze-drying, vacuum freeze-drying, lyophilization, or other cryogenic drying processes. The list of common solvents used is the same as the solvents in Method 1;
[0212] Method 15 (Lyophilization / Freeze-Drying Technology): The lyophilization method is a modification of the cryogenic technology. In this technology, the common solvent in the solution is removed by primary freezing and subsequent drying of the solution containing the "API" and "HOST substance" under reduced pressure. The basic freeze-drying process involves dissolving the "API" and "HOST substance" in a common solvent and then immersing it in a cryogenic liquid until it is completely frozen. Then, the frozen solution is further lyophilized;
[0213] Method 16 (Spray Freezing onto a Cryogenic Liquid): This method is a modification of the cryogenic technology. In this technology, the "API" and "HOST substance" are dissolved in a common solvent and atomized onto the surface of a boiling and agitated cryogenic liquid refrigerant;
[0214] Method 17 (Spray Freezing into a Cryogenic Liquid (SFL)): This method is a modification of the cryogenic technology. It combines direct liquid-liquid impingement (through spraying) between the solution and the cryogenic liquid to provide intense droplet atomization. Then, the frozen particles are lyophilized to obtain dry and free-flowing micropowder;
[0215] Method 18 (Spray Freezing into Vapor above Liquid (SFV / L)): This method is a modification of cryogenic technology. The “API” solution is frozen in the cryogenic liquid vapor and then the frozen solvent is removed. During the SFV / L process, the atomized droplets usually start to freeze in the vapor phase before contacting the cryogenic liquid. When the solvent freezes, the “API” becomes supersaturated in the unfrozen regions of the atomized droplets;
[0216] Method 19 (Ultra-rapid Freezing): This method is a modification of cryogenic technology. The “API” solution is applied to the solid surface of a cryogenic substrate, resulting in instant freezing and subsequent lyophilization;
[0217] Method 20 (Precipitation Technique, Co-precipitation Method): In the precipitation method, the “API” is dissolved in a solvent and then added to a non-solvent to precipitate the crystals. While stirring continuously, the non-solvent is dropped into the solution of “API” and “HOST Substance”. During the addition of the non-solvent, the “API” and “HOST Substance” co-precipitate to form microparticles. Finally, the resulting microparticle suspension is filtered and dried. The list of solvents used is the same as those listed in Method 1.
[0218] Method 21 (Microwave Radiation Method): This method involves a microwave radiation reaction between the “API” and the complexing agent using a microwave oven. The “API” and “HOST Substance” are dissolved in a mixture of water and / or organic solvents in a certain proportion to a container at a certain molar ratio. The mixture reaction is carried out in a microwave oven. After the reaction is completed, an appropriate amount of solvent mixture is added to the above reaction mixture to remove the remaining uncomplexed free “API” and “HOST Substance”. The resulting precipitate is separated by filtration and dried. The list of solvents used is the same as those listed in Method 1.
[0219] Method 22 (Energy Input Method): This method includes exposing the HOST Substance and the “API” to energy input until a highly bioavailable and highly permeable solid dispersion is formed in which the “API” is trapped as an amorphous material in the HOST Substance.
[0220] Method 23 (Thermal / Shear Energy Input Method): This method includes exposing the HOST Substance and the “API” to energy input, where the energy input is heat and / or shear force, until a highly bioavailable and highly permeable solid dispersion is formed in which the “API” is trapped as an amorphous material in the HOST Substance.
[0221] Method 24 (Combination Method): This method includes any combination of Methods 1 - 23.
[0222] Methods 1 - 24 should result in the formation of highly bioavailable solid dispersions.

[0258] Combination therapies can provide “synergy” and “synergistic effects”, i.e., when the active ingredients are used together, the effect achieved is greater than the sum of the effects when these compounds are used alone. Synergistic effects can be achieved when the active ingredients (1) are combined and administered or delivered simultaneously in a combination drug; (2) are delivered alternately or in parallel as separate drugs; or (3) by other regimens. When the drugs are used alternately, synergistic effects can be achieved when the compounds are administered or delivered sequentially, e.g., in separate tablets, pills or capsules, or in separate syringes for different injections. Generally, in alternation, the effective doses of each active ingredient are administered sequentially, i.e., continuously, while in combination therapy, the effective doses of two or more active ingredients are administered together. A synergistic antiviral effect means an antiviral effect that exceeds the pure additive effect of the individual compounds in the combination.
[0259] Kits containing compounds of FORMULA I-V are also provided. In some embodiments of the present invention, a single kit is provided, containing compounds selected from each of the formulas provided herein, and each of its subgroups and embodiments, including FORMULA II, FORMULA II, FORMULA IV, FORMULA V. In one aspect, the kit includes a compound of FORMULA I. Each individual kit described herein may include a label and / or instructions for administering to a subject in need (e.g., a human) to treat a disease or disorder. In some embodiments of the present invention, the disease or disorder is a human viral infection. In other embodiments of the present invention, each individual kit may further contain instructions for administering additional pharmaceutical agents in combination with the compound of FORMULA I to treat a disease or disorder in a subject in need (e.g., a human). In some embodiments of the present invention, the disease or disorder is a human viral infection. In each embodiment provided herein, there is also an embodiment in which the kit includes separate dosage units of the compounds described. Examples of separate dosages may include tablets, tablets, capsules, prefilled syringes or syringe cartridges, intravenous infusion bags, etc., each containing a therapeutically effective amount of the relevant compound. In some embodiments, the kit may contain a single dosage unit, while in other embodiments, the kit may contain multiple dosage units, e.g., the number of dosage units required for a particular regimen or period.
[0260] In certain embodiments, the product container can be a vial, jar, ampoule, prefilled syringe, blister pack, tin can, bottle, box or intravenous infusion bag.
[0261] Furthermore, certain embodiments of the present invention provide the use of a compound selected from each of FORMULA I-II herein in the preparation of a medicament for treating human diseases.

[0286] IV. Formulations and Pharmaceutical Compositions
[0287] The compounds of the present invention are formulated with common carriers and excipients, which are selected according to conventional practice. Tablets will contain excipients, preservatives, fillers, binders, etc. Aqueous formulations are prepared in a sterile form and are usually isotonic if they are not intended for oral administration. All formulations optionally contain excipients such as those described in the Handbook of Pharmaceutical Excipients (1986). Excipients include ascorbic acid and other antioxidants, chelating agents such as EDTA, sugars such as dextran, hydroxyalkylcellulose, hydroxyalkylmethylcellulose, stearic acid, etc. The pH of the formulations ranges from about 3 to about 11, but is usually between 7 and 10. In some embodiments of the present invention, the pH of the formulations ranges from about 2 to about 5, but is usually between 3 and 4.
[0288] While the active ingredients may be administered alone, it is preferred to present them as pharmaceutical compositions. The compositions of the present invention, whether for veterinary or human use, include at least one active ingredient, as described above, together with one or more acceptable carriers and optionally contain other therapeutic ingredients, particularly other therapeutic ingredients discussed herein. The carrier must be "acceptable", i.e., compatible with the other ingredients of the composition and physiologically harmless to the recipient.
[0289] These compositions include compositions suitable for the above-described routes of administration. The compositions may conveniently be presented in unit dosage form and may be prepared by any method well known in the pharmaceutical art. These methods and compositions are generally described in Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, Pa.). These methods involve bringing the active ingredient into association with a carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing the active ingredient into association with a liquid carrier or a finely divided solid carrier or both, and then shaping if necessary.
[0290] Formulations of the present invention suitable for oral administration may be presented in discrete unit forms such as capsules, sachets or tablets, each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may be administered as a bolus, paste or cream.
[0291] Tablets are made by compression or molding, optionally with the addition of one or more additional ingredients. Compressed tablets can be prepared by compressing the active ingredient in free-flowing form, such as a powder or granules, in a suitable machine, further mixed with a binder, lubricant, inert diluent, preservative, surfactant or dispersant. Molded tablets can be made by molding a mixture of powdered active ingredient moistened with an inert liquid diluent in a suitable machine. Tablets can additionally be coated with a shell or pellet and optionally formulated in a form that allows for slow or controlled release of the active ingredient.
[0292] For infections of the eye or other external tissues (such as the oral cavity and skin), the composition is preferably applied in the form of an ointment or cream containing the active ingredient, for example, in an amount of from 0.075 to 20% wt. (including the active ingredient in the range of 0.1% to 20% in 0.1% wt. increments, for example, 0.6% wt., 0.7% wt., etc.), more preferably from 0.2 to 15% wt., and most preferably from 0.5 to 10% wt. When formulated as an ointment, the active ingredient can be used with paraffin or a water-soluble ointment base. Alternatively, the active ingredient can be formulated as a cream with an oil-in-water cream base.
[0293] Optionally, the aqueous phase of the cream base can include (if desired) at least 30% wt. of a polyol, i.e., an alcohol having two or more hydroxyl groups, such as propylene glycol, butane-1,3-diol, mannitol, sorbitol, glycerol, polyethylene glycol (including PEG400) and mixtures thereof. The composition for topical use can preferably include a compound that enhances the absorption or penetration of the active ingredient through the skin or other affected area. Examples of such skin penetration enhancers include dimethyl sulfoxide and its analogs.
[0294] The oil phase of the emulsion of the present invention can be composed of known ingredients in a known manner. Although this phase can contain only an emulsifier (or emulsifying agent), preferably it contains at least one emulsifier together with a fat or oil or a mixture containing both a fat and an oil. Hydrophilic emulsifiers are preferably used together with lipophilic emulsifiers as stabilizers. It is also preferred to contain both oil and fat at the same time. The emulsifier (with or without a stabilizer) together constitutes a so-called emulsifying wax, and the emulsifying wax together with the oil and fat constitutes a so-called emulsifying ointment base, which forms the oily dispersed phase of the cream composition.
[0295] Emulsifiers and emulsion stabilizers suitable for the formulations of the present invention include 60, 80, cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glyceryl monostearate and sodium lauryl sulfate. Other emulsifiers and emulsion stabilizers suitable for the formulations of the present invention include 80.
[0296] The choice of oil or fat suitable for the formulation depends on achieving the desired cosmetic properties. Creams can be non-greasy, non-staining and washable products with an appropriate consistency to avoid leakage from tubes or other containers. Straight-chain or branched-chain alkyl esters, mono- or di-esters, such as diisoadipate, isocetostearate, propylene glycol dicaprylate, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a mixture of branched-chain esters known as Crodamol CAP, the latter three being preferred. They can be used alone or in combination, depending on the desired properties. As an alternative, high-melting-point lipids such as white soft paraffin and / or liquid paraffin or other mineral oils can also be used.
[0297] According to the present invention, the pharmaceutical composition comprises a combination with one or more pharmaceutically acceptable carriers or excipients and optionally other therapeutic agents. The pharmaceutical composition containing the active ingredient can be in any form suitable for the intended route of administration. For oral administration, the composition can be prepared, for example, as tablets, lozenges, troches, aqueous or oily suspensions, dispersible powders or granules, emulsions, hard or soft gelatin capsules, syrups or elixirs. The formulations for oral use can be prepared by any method known in the pharmaceutical art, and such compositions can contain one or more excipients, including sweetening agents, flavoring agents, coloring agents and preservatives, to provide a palatable preparation. Tablets containing the active ingredient admixed with non-toxic pharmaceutically acceptable excipients suitable for tablet production are acceptable. These excipients can be, for example, inert diluents such as calcium carbonate or sodium carbonate, lactose, calcium phosphate or sodium phosphate; granulating and disintegrating agents such as corn starch or alginic acid; binding agents such as starch, gelatin or gum arabic; and lubricants such as magnesium stearate, stearic acid or talc. Tablets can be uncoated or can be coated using known methods, including microencapsulation, to delay disintegration and absorption in the gastrointestinal tract and thereby provide a sustained action over an extended period of time. Delayed-release materials such as glyceryl monostearate or glyceryl distearate can be used alone or in combination with waxes.
[0298] The products for oral use can also be designed as hard gelatin capsules in which the active ingredient is admixed with an inert solid diluent such as calcium phosphate or kaolin, or as soft gelatin capsules in which the active ingredient is admixed with a water or oil medium such as peanut oil, liquid paraffin or olive oil.
[0299] The aqueous suspension according to the present invention comprises an active material mixed with excipients suitable for preparing an aqueous suspension. These excipients may include suspending agents such as sodium carboxymethylcellulose, methylcellulose, hydroxypropylmethylcellulose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum arabic, and dispersing or wetting agents such as naturally occurring phospholipids (such as lecithin), condensation products of alkyl oxides with fatty acids (such as polyethylene glycol stearate), condensation products of ethylene oxide with long-chain fatty alcohols (such as heptadecaethylene glycol), condensation products of ethylene oxide with partial esters of fatty acids and hexitol anhydrides (such as polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives such as ethyl or propyl p-hydroxybenzoate, one or more colorants, one or more flavorings, and one or more sweeteners such as sucrose or saccharin. Other non-limiting examples of suspending agents include cyclodextrin and Captisol.
[0300] The oily suspension can be prepared by suspending the active ingredient in a vegetable oil such as peanut oil, olive oil, sesame oil or coconut oil, or in a mineral oil such as liquid paraffin. A thickening agent such as beeswax, solid paraffin or cetyl alcohol can be included in the oral suspension. Sweeteners and flavorings as described above can be added to make a palatable oral preparation. These compositions can be preserved by adding an antioxidant such as ascorbic acid.
[0301] The dispersible powders and granules of the present invention, suitable for preparing or manufacturing an aqueous suspension by adding water, comprise an active ingredient mixed with a dispersing or wetting agent, a suspending agent and one or more preservatives. Suitable dispersing or wetting agents and suspending agents are those exemplified above. Additional excipients such as sweeteners, disintegrants and colorants may also be present.
[0302] The pharmaceutical composition of the present invention may also be presented as a water-in-oil emulsion. The oil phase may be a vegetable oil such as olive oil or peanut oil, a mineral oil such as liquid paraffin, or a mixture thereof. Suitable emulsifying agents include gums of natural origin such as gum arabic and gum tragacanth, phospholipids of natural origin such as soybean lecithin, esters or partial esters derived from fatty acids and hexitol anhydrides such as sorbitan monooleate, and condensation products of these partial esters with ethylene oxide such as polyoxyethylene sorbitan monooleate. The emulsion may also contain sweeteners and flavorings. Syrups and elixirs may contain sweeteners such as glycerol, sorbitol or sucrose. These formulations may also contain a lubricant, a preservative, a flavoring or a colorant.
[0303] The pharmaceutical composition of the present invention can be a sterile injectable preparation, such as a sterile aqueous injection solution or an oily suspension. This suspension can be prepared using the above-mentioned suitable dispersants or wetting agents and suspending agents according to the prior art. The sterile injectable preparation can also be a sterile injectable solution or suspension in a non-toxic acceptable diluent or solvent, such as a solution in 1,3-butanediol or prepared as a lyophilized powder. Acceptable carriers and solvents include water, Ringer's solution, and isotonic sodium chloride solution. In addition, a sterile fixed oil is usually used as a solvent or suspension medium. Any odorless fixed oil can be used for this purpose, including synthetic monoglycerides or diglycerides. In addition, fatty acids such as oleic acid can also be used to prepare injectable preparations. Acceptable carriers and solvents that can be used include water, isotonic Ringer's solution, isotonic sodium chloride solution, and hypertonic sodium chloride solution.
[0304] The amount of the active ingredient that can be combined with the carrier material to produce a single dosage form will vary depending on the recipient and the specific route of administration. For example, a human sustained-release formulation intended for oral administration may contain about 1 to 1000 milligrams of the active ingredient, combined with a suitable and convenient amount of carrier material, which can account for about 5% to about 95% (by weight) of the total amount of the composition. The pharmaceutical composition can be prepared into a dosage amount convenient for measurement. For example, an aqueous solution intended for intravenous infusion may contain about 3 to 500 picograms of the active ingredient per milliliter of solution, providing an appropriate infusion volume at a rate of about 30 milliliters per hour.
[0305] Formulations suitable for topical use in the eye also include eye drops, in which the active ingredient is dissolved or suspended in a suitable carrier, especially an aqueous solution of the active ingredient. The concentration of the active ingredient in such a composition is preferably from 0.5% to 20%, more preferably from 0.5% to 10%, especially about 1.5% w / w.
[0306] Formulations suitable for topical use in the mouth include lozenges containing the active ingredient, usually made from a flavoring base of sucrose and gum arabic or tragacanth; lozenges containing the active ingredient made from an inert matrix of gelatin and glycerol or sucrose and gum arabic; and mouthwashes containing the active ingredient, with a suitable liquid carrier.
[0307] Formulations suitable for rectal administration can be in the form of suppositories, with a suitable matrix, including for example cocoa butter or salicylates.
[0308] Formulations suitable for pulmonary or nasal administration have a particle size, for example, in the range of 0.1 to 500 micrometers, such as 0.5, 1, 30, 35, etc., and reach the alveolar sacs by rapid inhalation through the nose or inhalation through the mouth. Suitable compositions include aqueous or oily solutions of the active ingredient. Formulations suitable for administration as an aerosol or dry powder can be prepared according to conventional methods and can be delivered together with other therapeutic agents, such as compounds for the treatment or prevention of viral infections or viral diseases, as described below.
[0309] Formulations suitable for vaginal administration may be in the form of vaginal suppositories, tampons, creams, gels, pastes, foams or sprays and, in addition to the active ingredient, contain carriers known in the art to be appropriate.
[0310] Formulations suitable for parenteral administration include aqueous and non-aqueous sterile solutions for injection which may contain antioxidants, buffers, bacteriostats and solutes which render the formulation isotonic with the blood of the intended recipient; and aqueous and non-aqueous sterile suspensions which may include suspending and thickening agents.
[0311] These formulations are presented in single-dose or multi-dose containers, for example sealed ampoules and vials, and may be stored in a freeze-dried (lyophilized) state, requiring only the addition immediately prior to use of a sterile liquid carrier, for example water for injection.

[0373] The compounds of FORMULA I-V described herein can be administered in solid or liquid dosage forms (e.g., orally). In both cases, the compound can be encapsulated in a material to protect it from acids and other natural conditions that may inactivate the compound. The compound can be made into aqueous solutions, liquid dispersions, (swallowable) tablets, buccal tablets, lozenges, capsules, elixirs, powders, granules, ointments, adhesive skin patches, sprays, suspensions, syrups, and wafers. These dosage forms can include pharmaceutically acceptable excipients, diluents, and / or carriers such as binders, disintegrants, emulsifiers, lubricants, flavorings, antioxidants, and preservatives. Liquid dosage forms can include diluents such as normal saline or aqueous buffers.
[0374] Any route of administration of FORMULA I-V can be selected in the methods described herein. For example, the route of administration can be selected from oral, nasal, topical, buccal, rectal, vaginal, ophthalmic, subcutaneous, intramuscular, intraperitoneal, epidural, intravenous, intraarterial, intratumoral, spinal, intrathecal, intra-articular, intraarterial, subarachnoid, sublingual, oral mucosa, pulmonary, bronchial, lymphatic, intrauterine, subcutaneous, intratumoral, integrated on an implantable device, intradural, intracortical, intradermal, cutaneous, epidermal, transdermal, vaginal, rectal, ocular (e.g., transconjunctival), intraocular, ureteral, and parenteral. An advantage of the compounds of the present invention is that they have high bioavailability and can be administered orally. The preferred route of administration is oral.
[0375] In the method for treating viral infections of the present invention, the compounds of the present invention can be administered at any time when contacting a person suffering from a viral infection or a person already infected with a virus. In some embodiments, the compounds of the present invention can be prophylactically administered to a person in contact with a person suffering from a viral infection. In some embodiments of the present invention, the compounds of the present invention can be administered to a person who tests positive but has no symptoms of viral infection. In some embodiments of the present invention, the compounds of the present invention can be administered after the appearance of symptoms of viral infection.
[0376] The effective dose of the active ingredient depends at least on the nature of the disease being treated, its toxicity, whether the compound is used prophylactically (lower dose) or to treat an active viral infection, the method of administration and the pharmaceutical formulation, and is determined by the doctor through conventional dose escalation studies. The expected range can be from about 0.0001 to about 100 mg / kg body weight per day; usually from about 0.01 to about 10 mg / kg body weight per day; more usually from about 0.01 to about 5 mg / kg body weight per day; most usually from about 0.2 to about 1 mg / kg body weight per day. For example, for an adult with a body weight of about 70 kg, the daily candidate dose is about 1 mg to 1000 mg, preferably 5 mg to 500 mg, and can be a single or multiple doses. All doses are based on the equivalent amount of pure "API".
[0377] The effective dose of the compounds of the present invention for treating viral infections may depend on whether it is used prophylactically or to treat a person already infected with a virus. In addition, the dose may also depend on whether the person infected with the virus has not yet shown symptoms or has already shown symptoms of viral infection. Persons who test positive and show symptoms of viral infection may require a higher dose of treatment, whereas the dose for those receiving prophylactic treatment may be lower.
[0378] Suitable dosing periods are conceivable. For example, the dosing time can be from 1 day to 100 days, including 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80 or 90 days. The dosing time can also be from 1 week to 15 weeks, including 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 weeks. Longer dosing periods are also recommended. The dosing time may depend on whether the compound is administered prophylactically or to treat a person infected with a virus. For example, prophylactic administration can be carried out during continuous contact with other persons infected with a virus and for an appropriate period of time after the last contact with the person infected with a virus. For a person already infected with a virus, the treatment time can be any duration required to treat the patient, as well as an appropriate period of time after testing negative for viral infection to ensure that the viral infection does not recur.
[0379] VI. Examples
[0380] A. Preparation of Compounds
[0381] Example 1.
[0382] Medicinal-grade ivermectin, CAS No. 70288-86-7, was purchased from Aecochem Co., Ltd., Xiamen, China. Apple pectin was purchased from Ronas Chemical Industry Co., Ltd., Chengdu, China. All other chemicals were of analytical grade and were not further purified.
[0383] The compound of FORMULA 1 was prepared by Method 1. Mechanochemical synthesis of the solid dispersion was carried out using a roller ball mill. Processing mode: driving speed was 400 rpm, grinding jar speed was 100 rpm, grinding jar volume was 2000 ml, grinding medium was steel balls (diameter 12 mm, loading amount 800 g), and the processing time varied from 2 to 24 hours. The sample was a loose powder (particle size from 0.1 to 10 microns). The compositions and results of obtaining highly bioavailable solid dispersions using FORMULA I are shown in Table 2.
[0384] Table 2. The compound of FORMULA I obtained in Example 1.
[0385]
[0386] Example 2.
[0387] The compound of FORMULA 1 was prepared by Method 10. Acetone or ethanol (refined 96%) was used as the organic solvent: 40 - 70 parts of the solvent were used per 100 parts of the polymer and avermectin mixture (calculated by gram equivalent). These solvents could dissolve the polymer matrix. After thoroughly stirring the polymer and avermectin wetted with the solvent in a mortar to form a dough-like substance, and after drying by solvent evaporation. The dried polymer substance could be ground using a ball mill or other grinding machines, and the particle size of the polymer product should not exceed 5 - 9 microns. The compositions and results of obtaining highly bioavailable nanocomposites using FORMULA I are shown in Table 3.
[0388] Table 3. The compound of FORMULA I obtained in Example 2.
[0389]
[0390] Example 3.
[0391] The compound of FORMULA 1 is obtained using Method 6. Ivermectin and PVA - polypropylene glycol graft copolymer are used to prepare a solid dispersion. Thermal stage extrusion is carried out using a co - rotating, fully meshing conical mini twin - screw extruder. The temperature is set at 195 °C, and the screw speed varies between 90 and 105 rpm. 7.5 grams are fed manually for each run; the internal circulation time after feeding is 5 minutes. The extrudate is collected after cooling to ambient temperature on a conveyor belt. The extruded samples are then ground in a laboratory mill for 4 minutes and sieved to remove particles with a particle size greater than 400 microns.
[0392] B. Bioavailability study
[0393] Example 4. Study of the concentration of ivermectin in bovine plasma
[0394] The free ivermectin substance is processed in a planetary ball mill with the following parameters: material weight - 5 grams, grinding jar volume - 200 ml, grinding medium - steel balls (diameter 8 mm, load 90.0 grams), processing time - 20 minutes. The compound of FORMULA I is processed according to Example 1 №1.
[0395] The cows are divided into 2 groups of 1 cow each. Free ivermectin (IVM) and the compound of FORMULA I are orally administered to the fasting cows. Blood samples are taken from the jugular vein at appropriate time intervals (0, 4, 20 hours) after administration.
[0396] The concentration of ivermectin in plasma is analyzed according to the method of Na - Bangchang, K. High - performance liquid chromatography (HPLC) is used to determine ivermectin in plasma, see Southeast Asian J Trop Med Public Health, September 2006, 37(5):848 - 58, PMID: 17333725.
[0397] The internal standard (moxidectin) and ivermectin are separated on a Hypersil Gold C18 column (150x4.6 mm, 5 - micron particle size) with retention times of 3.7 and 7.0 minutes respectively. Fluorescence detection is set with excitation and emission wavelengths of 365 and 475 nm respectively. The mobile phase consists of acetonitrile, methanol, and distilled water (50:45:5, v / v / v) and passes through the column at a flow rate of 1.5 ml / min. Chromatographic analysis is carried out at 25 °C. Sample preparation (100 μl plasma) is carried out by one - step protein precipitation with acetonitrile, followed by derivatization with an N - methylimidazole solution (1:1, v / v) in 100 μl acetonitrile and a trifluoroacetic acid anhydrous solution (1:2, v / v) in 150 μl acetonitrile. The calibration curve for a concentration range of 20 - 8,000 ng / ml plasma is linear with a correlation coefficient better than 0.995.
[0398] All blood samples were centrifuged at 3000 rpm for 15 minutes to obtain serum. Bovine plasma samples (100 μL each) were placed in 1.5 mL Eppendorf tubes and then subjected to protein precipitation. The samples were vortexed for 1 minute and then centrifuged at 13,400 rpm for 10 minutes. 20 μL of the supernatant was injected into the HPLC.
[0399] The pharmacokinetic parameters of ivermectin and the FORMULA I compound are shown in Figure 2 and Table 4. The results showed a significant increase in the bioavailability and permeability of the FORMULA I compound. Oral administration of FORMULA I 600 μg / kg IVM can exceed the EC 50 of SARS-CoV-2, which is 2.4 μM.
[0400] Table 4. Pharmacokinetic parameters after oral administration of ivermectin and the FORMULA I compound (ivermectin concentration)
[0401]
[0402] C. Permeability study
[0403] Example 5. Permeability of solid dispersions or non-covalent complexes on the Caco-2 cell line
[0404] The Caco-2 cell line is a standard in vitro model for evaluating the permeability of drugs through the gastrointestinal wall. These cells retain almost all the morphological and functional characteristics of intestinal epithelial cells, including the expression of multi-drug resistance proteins such as P-glycoprotein. Generally, the data obtained in such experiments has a good correlation with the bioavailability of drugs in vivo.
[0405] Caco-2 cells were cultured in Dulbecco's medium in a standard manner, supplemented with 10% heat-inactivated fetal bovine serum (FBS, USA). The permeability study through the Caco-2 cell monolayer was carried out according to the standard procedure. A Transwell 12-well plate (Corning, USA) containing a 0.4 μm polyester membrane was used, and the cells were seeded at a density of 1x105 cells per well. Before the experiment, the cells were grown in IMDM medium supplemented with 10% FBS. The medium was changed every two days. The integrity of the cell monolayer was evaluated by measuring the transepithelial electrical resistance (TEER) at the beginning and end of the experiment using a Millicell ERS-2 (Millipore, USA). The test substance (FORMULA I compound treated according to Example 1 No. 2) was dissolved in Hank's balanced salt solution (HBSS) at a concentration of 3 μM (calculated as pure IVM). Ivermectin was also dissolved in Hank's balanced salt solution at the same concentration of 3 μM.
[0406] The test solution was added to the top of the wells, and the bottoms of the wells were filled with pure HBSS. Then, the wells were incubated at 37.5 °C and shaken on an orbital shaker at 100 rpm. 100 μL samples were taken from the bottoms of the wells at 20, 40, 60, 80, 100, and 120 minutes. The required volume was immediately replenished with fresh HBSS solution after sampling. The substance concentration was determined by an Agilent 1200 high performance liquid chromatograph (equipped with an ultraviolet detector). Chromatographic analysis was performed on a reversed-phase column. The permeability coefficient was calculated according to the formula published in the literature.
[0407] Table 5. Comparison of the permeability of IVM non-covalent complexes through Caco-2 cell monolayers with pure IVM at similar points
[0408]
[0409] Therefore, the non-covalent ivermectin complex has better permeability than pure ivermectin.
[0410] D. Toxicity study
[0411] Example 6. Toxicity of solid dispersions or non-covalent complexes
[0412] The compounds of FORMULA I were processed according to Example 1 №2. The results of the oral toxicity (for Syrian hamsters) of the compounds of FORMULA I showed that the LD50 of pure ivermectin = 340 mg / kg, while the LD50 of pure ivermectin = 62 mg / kg, that is, the toxicity of the compounds of FORMULA I was reduced by 5.48 times.
[0413] F. Spectroscopy
[0414] Example 7. Spectroscopic analysis of non-covalent complexes
[0415] The compounds of FORMULA I were processed according to Example 1 №2. In the infrared spectrum of the obtained non-covalent complex, the valence vibration frequency of the hydroxyl group was manifested as a broad shoulder peak, which indicated the presence of intermolecular hydrogen bonds during the complex formation. Based on the infrared spectroscopic analysis, it was determined that the non-covalent complex was stable due to the presence of intermolecular hydrogen bonds.
[0416] To confirm the physicochemical values and chemical structure of the non-covalent complex and to more accurately analyze the formation of the main molecular ions, the mass spectrometry of the complex was analyzed by liquid chromatography-mass spectrometry (TOF LC-MS, Agilent Technologies). The mass spectrometry analysis showed that in addition to the peaks belonging to the individual carrier and API components, there were also peaks corresponding to various heterogeneous non-covalent structural compositions. The presence of ions corresponding to the molecular ions of the non-covalent complex in the mass spectrometry indicated that the carrier and API molecules formed a non-covalent complex due to mutual non-covalent interactions.
[0417] G. Antiviral activity
[0418] Another aspect of the present invention relates to methods for inhibiting viral infection, including treating a sample or a subject suspected of requiring such inhibition with a composition of the present invention. In the context of the present invention, samples suspected of containing a virus include natural or artificial materials such as organisms; tissue or cell cultures; biological samples such as biological material samples (blood, serum, urine, cerebrospinal fluid, tears, sputum, saliva, tissue samples, etc.); laboratory samples; food, water or air samples; biological product samples such as cell extracts, especially recombinant cell extracts for synthesizing the required glycoproteins, etc. Generally, the sample will be suspected of containing an organism that induces viral infection, usually a pathogen such as an oncovirus. The sample can be contained in any medium, including water and organic solvent / water mixtures. Samples include organisms such as humans, as well as artificial materials such as cell cultures.
[0419] If desired, after application of the composition, the antiviral activity of the compounds of the present invention can be observed by any method, including methods for directly and indirectly detecting such activity. Methods for quantitatively, qualitatively and semi-quantitatively determining such activity are all contemplated. Generally, one of the above screening methods is applied, but any other method, such as observing the physiological characteristics of an organism, is also applicable.
[0420] The antiviral activity of the compounds of the present invention can be measured using known standard screening protocols. For example, several general protocols can be used to measure the antiviral activity of a compound.
[0421] Example 8. Human blood oxygen saturation study
[0422] The blood oxygen saturation of a symptomatic male patient and another symptomatic male patient who tested positive for SARS-CoV-2 was measured. The compound of FORMULA I was treated according to Example 1 №3.
[0423] Humans were divided into 2 groups, with 1 person in each group. The compound of FORMULA I of 600 μg / kg pure ivermectin was orally administered to the humans in the second group. Blood oxygen saturation was extracted at appropriate time intervals (0, 24, 48, 72, 96 hours) after administration.
[0424] The change in oxygen saturation of each study group on days 0 - 4 is shown in Table 6 and Figure 3. As shown in Table 6 and Figure 3, the people who received the compound of FORMULA I showed a recovery of the saturation level related to SARS-CoV-2 infection compared to those who did not receive treatment. As shown in Figure 3, the people who received the compound of FORMULA I had significantly reduced infectious virus on days 1 and 2 after infection. These data show that the compound of FORMULA I reduced the replication of SARS-CoV-2 in the lungs.
[0425] Table 6. Blood oxygen saturation before treatment and after oral administration of FORMULA I compounds.
[0426]
[0427] Example 9. Human SARS-CoV-2 viral load study
[0428] The viral load of a symptomatic male patient tested positive for SARS-CoV-2 was measured. The compound of FORMULA I was processed according to Example 2 №2.
[0429] Before use, the SARS-CoV-2 viral load in nasopharyngeal swab samples stored at -40 °C was quantified. Viral RNA was isolated from the stored samples using the QIAamp Viral RNA Mini Kit (Qiagen, Hilden, Germany).
[0430] Then, quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) targeting the SARS-CoV-2 N gene was performed. The standard curve was constructed by serial dilution of in vitro transcribed viral RNA in a cellular RNA matrix, and the cellular RNA was from nasopharyngeal negative samples.
[0431] This assay included measurement of a housekeeping gene as an internal control and normalization gene. The cycle threshold (Ct) of the housekeeping gene was used to correct the specific SARS-CoV-2 Ct value according to the number of cells in the sample. Therefore, the viral load measurement results were expressed as log10 copies per reaction.
[0432] Before oral administration of the FORMULA I compound, the log10 value of the viral load was 6.3 copies / mL, and 24 hours after oral administration of 1200 μg / kg (per pure ivermectin) of FORMULA I, the log10 value of the viral load was 5.1 copies / mL. The log10 value of the viral load at the start of treatment (6.3 copies / mL) was significantly different from the log10 value of the viral load 24 hours after the start of treatment (5.1 copies / mL). These data indicate that the compound of FORMULA I can reduce the replication of SARS-CoV-2.

[0434] Patient 1, log10 copies per ml, Compound of Formula I, 1200 μg / kg (per pure ivermectin) 0h 6.3 24h 5.1
[0435] Example 10. Patient study
[0436] Dengue, chikungunya, yellow fever, and Zika are common in the tropics, South and Central America, Mexico (including Veracruz, Jalisco, Chiapas, Oaxaca, and Quintana Roo), and the Caribbean. The virus is transmitted by female Aedes aegypti and Aedes albopictus mosquitoes.
[0437] A 38-year-old male tested positive for NS1, which detects the non-structural NS1 protein of the dengue virus. Symptoms included a high fever of 40 °C / 104 °F, severe headache, nausea, and muscle aches. The patient was orally administered a compound of FORMULA I (obtained according to Example 1 No. 2) mixed with 300 ml of water at a dose of 800 μg / kg of pure ivermectin. The compound was administered orally. The patient's fever gradually subsided, muscle pain recovered, and the illness disappeared after another 2 days.
