Other compositions, methods, features, and advantages will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional compositions, methods, features and advantages be included within this description, be within the scope of the present disclosure, and be protected by the accompanying claims.
Further aspects of the present disclosure will be readily appreciated upon review of the detailed description, described below, when taken in conjunction with the accompanying drawings.
Many modifications and other embodiments disclosed herein will come to mind to one skilled in the art to which the disclosed compositions and methods pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the disclosures are not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. The skilled artisan will recognize many variants and adaptations of the aspects described herein. These variants and adaptations are intended to be included in the teachings of this disclosure and to be encompassed by the claims herein.
Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
As will be apparent to those of skill in the art upon reading this disclosure, each of the individual embodiments described and illustrated herein has discrete components and features which may be readily separated from or combined with the features of any of the other several embodiments without departing from the scope or spirit of the present disclosure.
Any recited method can be carried out in the order of events recited or in any other order that is logically possible. That is, unless otherwise expressly stated, it is in no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not specifically state in the claims or descriptions that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow, plain meaning derived from grammatical organization or punctuation, or the number or type of aspects described in the specification.
While aspects of the present disclosure can be described and claimed in a particular statutory class, such as the system statutory class, this is for convenience only and one of skill in the art will understand that each aspect of the present disclosure can be described and claimed in any statutory class.
It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the disclosed compositions and methods belong. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the specification and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly defined herein.
Prior to describing the various aspects of the present disclosure, the following definitions are provided and should be used unless otherwise indicated. Additional terms may be defined elsewhere in the present disclosure.
As used herein, “comprising” is to be interpreted as specifying the presence of the stated features, integers, steps, or components as referred to, but does not preclude the presence or addition of one or more features, integers, steps, or components, or groups thereof. Moreover, each of the terms “by”, “comprising,” “comprises”, “comprised of,” “including,” “includes,” “included,” “involving,” “involves,” “involved,” and “such as” are used in their open, non-limiting sense and may be used interchangeably. Further, the term “comprising” is intended to include examples and aspects encompassed by the terms “consisting essentially of” and “consisting of.” Similarly, the term “consisting essentially of” is intended to include examples encompassed by the term “consisting of” as well as other chemicals or minor impurities that are not active and do not impact treating the condition, in other words, the composition only includes the listed active agents but other non-active component can be present.
It should be noted that ratios, concentrations, amounts, and other numerical data can be expressed herein in a range format. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms a further aspect. For example, if the value “about 10” is disclosed, then “10” is also disclosed.
When a range is expressed, a further aspect includes from the one particular value and/or to the other particular value. For example, where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure, e.g. the phrase “x to y” includes the range from ‘x’ to ‘y’ as well as the range greater than ‘x’ and less than ‘y’. The range can also be expressed as an upper limit, e.g. ‘about x, y, z, or less’ and should be interpreted to include the specific ranges of ‘about x’, ‘about y’, and ‘about z’ as well as the ranges of ‘less than x’, less than y′, and ‘less than z’. Likewise, the phrase ‘about x, y, z, or greater’ should be interpreted to include the specific ranges of ‘about x’, ‘about y’, and ‘about z’ as well as the ranges of ‘greater than x’, greater than y′, and ‘greater than z’. In addition, the phrase “about ‘x’ to ‘y’”, where ‘x’ and ‘y’ are numerical values, includes “about ‘x’ to about ‘y”.
It is to be understood that such a range format is used for convenience and brevity, and thus, should be interpreted in a flexible manner to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. To illustrate, a numerical range of “about 0.1% to 5%” should be interpreted to include not only the explicitly recited values of about 0.1% to about 5%, but also include individual values (e.g. about 1%, about 2%, about 3%, and about 4%) and the sub-ranges (e.g. about 0.5% to about 1.1%; about 5% to about 2.4%; about 0.5% to about 3.2%, and about 0.5% to about 4.4%, and other possible sub-ranges) within the indicated range.
As used herein, the terms “about,” “approximate,” “at or about,” and “substantially” mean that the amount or value in question can be the exact value or a value that provides equivalent results or effects as recited in the claims or taught herein. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art such that equivalent results or effects are obtained. In some circumstances, the value that provides equivalent results or effects cannot be reasonably determined. In such cases, it is generally understood, as used herein, that “about” and “at or about” mean the nominal value indicated ±10% variation unless otherwise indicated or inferred. In general, an amount, size, formulation, parameter or other quantity or characteristic is “about,” “approximate,” or “at or about” whether or not expressly stated to be such. It is understood that where “about,” “approximate,” or “at or about” is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise.
As used herein, the term “effective amount” refers to an amount that is sufficient to achieve the desired modification of a physical property of the composition or material. For example, an “effective amount” of a pharmaceutical composition refers to an amount that is sufficient to achieve the desired improvement in the property modulated by the formulation component, e.g. achieving the desired level of treatment. The specific level in terms of wt % in a composition required as an effective amount will depend upon a variety of factors including the amount and type of pharmaceutical composition, the subject, severity of illness, and the like.
As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.
As used herein, “therapeutic agent” can refer to any substance, compound, molecule, and the like, which can be biologically active or otherwise can induce a pharmacologic, immunogenic, biologic and/or physiologic effect on a subject to which it is administered to by local and/or systemic action, where the therapeutic agent can be present in a pharmaceutical composition. A therapeutic agent can be a primary active agent, or in other words, the component(s) of a composition to which the whole or part of the effect of the composition is attributed. A therapeutic agent can be a secondary therapeutic agent, or in other words, the component(s) of a composition to which an additional part and/or other effect of the composition is attributed. The term therefore encompasses those compounds or chemicals traditionally regarded as drugs and the like. Examples of therapeutic agents are described in well-known literature references such as the Merck Index (14th edition), the Physicians' Desk Reference (64th edition), and The Pharmacological Basis of Therapeutics (12th edition), and they include, without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of a disease or illness; substances that affect the structure or function of the body, or pro-drugs, which become biologically active or more active after they have been placed in a physiological environment. The agent may be a biologically active agent used in medical, including veterinary, applications and in agriculture, such as with plants, as well as other areas. The term therapeutic agent also includes without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of disease or illness; or substances which affect the structure or function of the body; or pro-drugs, which become biologically active or more active after they have been placed in a predetermined physiological environment.
As used herein, “kit” means a collection of at least two components constituting the kit. Together, the components constitute a functional unit for a given purpose. Individual member components may be physically packaged together or separately. For example, a kit comprising an instruction for using the kit may or may not physically include the instruction with other individual member components. Instead, the instruction can be supplied as a separate member component, either in a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation.
As used herein, “instruction(s)” means documents describing relevant materials or methodologies pertaining to a kit. These materials may include any combination of the following: background information, list of components and their availability information (purchase information, etc.), brief or detailed protocols for using the kit, trouble-shooting, references, technical support, and any other related documents. Instructions can be supplied with the kit or as a separate member component, either as a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation. Instructions can comprise one or multiple documents, and are meant to include future updates.
As used herein, “attached” can refer to covalent or non-covalent interaction between two or more molecules. Non-covalent interactions can include ionic bonds, electrostatic interactions, van der Walls forces, dipole-dipole interactions, dipole-induced-dipole interactions, London dispersion forces, hydrogen bonding, halogen bonding, electromagnetic interactions, π-π interactions, cation-π interactions, anion-π interactions, polar π-interactions, and hydrophobic effects.
As used interchangeably herein, “subject,” “individual,” or “patient” can refer to a vertebrate organism, such as a bird, reptile, amphibian, mammal (e.g. human, canine, feline, equine, cattle, etc.). In an aspect, the subject is a human. In an aspect, the subject is a domesticated animal such as a dog or cat. “Subject” can also refer to a cell, a population of cells, a tissue, an organ, or an organism, preferably to human and constituents thereof.
As used herein, the terms “treating” and “treatment” can refer generally to obtaining a desired pharmacological and/or physiological effect. The effect can be, but does not necessarily have to be, prophylactic in terms of preventing or partially preventing a disease, symptom or condition thereof, such as infections and consequences thereof. The effect can be therapeutic in terms of a partial or complete cure of a disease, condition, symptom or adverse effect attributed to the disease, disorder, or condition. The term “treatment” as used herein can include any treatment of infections such as COVID-19 infections (or other virus) and mutants and variants thereof in a subject, particularly a human and can include any one or more of the following: (a) preventing the disease from occurring in a subject which may be predisposed to the disease but has not yet been diagnosed as having it; (b) inhibiting the disease, i.e., arresting its development; and (c) relieving the disease, i.e., mitigating or ameliorating the disease and/or its symptoms or conditions. The term “treatment” as used herein can refer to both therapeutic treatment alone, prophylactic treatment alone, or both therapeutic and prophylactic treatment. Those in need of treatment (subjects in need thereof) can include those already with the disorder and/or those in which the disorder is to be prevented. As used herein, the term “treating”, can include inhibiting the disease, disorder or condition, e.g., impeding its progress; and relieving the disease, disorder, or condition, e.g., causing regression of the disease, disorder and/or condition. Treating the disease, disorder, or condition can include ameliorating at least one symptom of the particular disease, disorder, or condition, even if the underlying pathophysiology is not affected, e.g., such as treating the pain of a subject by administration of an analgesic agent even though such agent does not treat the cause of the pain.
As used herein, “dose,” “unit dose,” or “dosage” can refer to physically discrete units suitable for use in a subject, each unit containing a predetermined quantity of a disclosed compound and/or a pharmaceutical composition thereof calculated to produce the desired response or responses in association with its administration. In an aspect, the dosage for administering to a subject (e.g., a mammal, specifically a human) each active agent the present disclosure is about 2 to 60 micrograms/kilogram, where dosage can be adjusted as needed based on the active agent, the type of subject, the condition of the subject, the state of the disease or condition (e.g., COVID-19 condition or disease), and the like.
As used herein, “therapeutic” can refer to treating, healing, and/or ameliorating a disease, disorder, condition, or side effect, or to decreasing in the rate of advancement of a disease, disorder, condition, or side effect.
As used herein, the term “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors within the knowledge and expertise of the health practitioner and which may be well known in the medical arts. In the case of treating a particular disease or condition, in some instances, the desired response can be inhibiting the progression of the disease or condition. This may involve only slowing the progression of the disease temporarily. However, in other instances, it may be desirable to halt the progression of the disease permanently. This can be monitored by routine diagnostic methods known to one of ordinary skill in the art for any particular disease. The desired response to treatment of the disease or condition also can be delaying the onset or even preventing the onset of the disease or condition.
For example, it is well within the skill of the art to start doses of a compound (e.g., active agent) at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. It is generally preferred that a maximum dose of the pharmacological agents of the disclosure (alone or in combination with other therapeutic agents) be used, that is, the highest safe dose according to sound medical judgment. It will be understood by those of ordinary skill in the art however, that a patient may insist upon a lower dose or tolerable dose for medical reasons, psychological reasons or for virtually any other reasons.
A response to a therapeutically effective dose of a disclosed compound (e.g., active agent) and/or pharmaceutical composition (e.g., including the active agent), for example, can be measured by determining the physiological effects of the treatment or medication, such as the decrease or lack of disease symptoms following administration of the treatment or pharmacological agent. Other assays will be known to one of ordinary skill in the art and can be employed for measuring the level of the response. The amount of a treatment may be varied for example by increasing or decreasing the amount of a disclosed compound and/or pharmaceutical composition, by changing the disclosed compound and/or pharmaceutical composition administered, by changing the route of administration, by changing the dosage timing and so on. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products.
As used herein, the term “prophylactically effective amount” refers to an amount effective for preventing onset or initiation of a disease or condition (e.g., COVID-19 infection or other viral infection).
As used herein, the term “prevent” or “preventing” refers to precluding, averting, obviating, forestalling, stopping, or hindering something from happening, especially by advance action. It is understood that where reduce, inhibit or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed.
As used herein, “administering” can refer to an administration that is oral, topical, intravenous, subcutaneous, transcutaneous, transdermal, intramuscular, intra-joint, parenteral, intra-arteriole, intradermal, intraventricular, intraosseous, intraocular, intracranial, intraperitoneal, intralesional, intranasal, intracardiac, intraarticular, intracavernous, intrathecal, intravireal, intracerebral, and intracerebroventricular, intratympanic, intracochlear, rectal, vaginal, by inhalation, by catheters, stents or via an implanted reservoir or other device that administers, either actively or passively (e.g. by diffusion) a composition the perivascular space and adventitia.
In a particular aspect, administering refers administration non-orally. For example non-oral administration includes topical, intravenous, subcutaneous, transcutaneous, transdermal, intramuscular, intra-joint, parenteral, intra-arteriole, intradermal, intraventricular, intraosseous, intraocular, intracranial, intraperitoneal, intralesional, intranasal, intracardiac, intraarticular, intracavernous, intrathecal, intravireal, intracerebral, and intracerebroventricular, intratympanic, intracochlear, rectal, vaginal, by inhalation, by catheters, stents or via an implanted reservoir or other device that administers, either actively or passively (e.g. by diffusion) a composition the perivascular space and adventitia.
The term “parenteral” can include subcutaneous, intravenous, intramuscular, intra-articular, intra-synovial, intrasternal, intrathecal, intralesional, and intracranial injections or infusion techniques.
In an aspect, administration is via inhalation. Administration can be continuous or intermittent. In various aspects, a composition or agent can be administered therapeutically; that is, administered to treat an existing disease or condition. In further various aspects, a composition or agent can be administered prophylactically; that is, administered for prevention of a disease or condition.
The disclosed composition (e.g., pharmaceutical composition including the active agent) or active agent can include those suitable for oral, rectal, topical, pulmonary, nasal, and parenteral administration (e.g., and in particular, rectal, topical, pulmonary, nasal, and parenteral administration), although the most suitable route in any given case will depend on the particular subject, and nature and severity of the conditions for which the active agent is being administered. In a further aspect, the disclosed composition (e.g., pharmaceutical composition) or agent can be formulated to allow administration orally, nasally, via inhalation, parenterally, transmucosally, transdermally, intramuscularly, intravenously, intradermally, subcutaneously, intraperitoneally, intraventricularly, intracranially and intratumorally (e.g., and in particular, nasally, via inhalation, parenterally, transmucosally, transdermally, intramuscularly, intravenously, intradermally, subcutaneously, intraperitoneally, intraventricularly, intracranially and intratumorally).
The term “pharmaceutically acceptable” describes a material that is not biologically or otherwise undesirable, i.e., without causing an unacceptable level of undesirable biological effects or interacting in a deleterious manner.
The term “pharmaceutically acceptable salts”, as used herein, means salts of the active principal agents which are prepared with acids or bases that are tolerated by a biological system or tolerated by a subject or tolerated by a biological system and tolerated by a subject when administered in a therapeutically effective amount. When compounds of the present disclosure contain relatively acidic functionalities, base addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired base, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable base addition salts include, but are not limited to; sodium, potassium, calcium, ammonium, organic amino, magnesium salt, lithium salt, strontium salt or a similar salt. When compounds of the present disclosure contain relatively basic functionalities, acid addition salts can be obtained by contacting the neutral form of such compounds with a sufficient amount of the desired acid, either neat or in a suitable inert solvent. Examples of pharmaceutically acceptable acid addition salts include, but are not limited to; those derived from inorganic acids like hydrochloric, hydrobromic, nitric, carbonic, monohydrogencarbonic, phosphoric, monohydrogenphosphoric, dihydrogenphosphoric, sulfuric, monohydrogensulfuric, hydriodic, or phosphorous acids and the like, as well as the salts derived from relatively nontoxic organic acids like acetic, propionic, isobutyric, maleic, malonic, benzoic, succinic, suberic, fumaric, lactic, mandelic, phthalic, benzenesulfonic, p-tolylsulfonic, citric, tartaric, methanesulfonic, and the like. Also included are salts of amino acids such as arginate and the like, and salts of organic acids like glucuronic or galactunoric acids and the like.
The term “pharmaceutically acceptable ester” refers to esters of compounds of the present disclosure which hydrolyze in vivo and include those that break down readily in the human body to leave the parent compound or a salt thereof. Examples of pharmaceutically acceptable, non-toxic esters of the present disclosure include C 1 -to-C 6 alkyl esters and C 5-to-C 7 cycloalkyl esters, although C 1 -to-C 4 alkyl esters are preferred. Esters of disclosed compounds can be prepared according to conventional methods. Pharmaceutically acceptable esters can be appended onto hydroxy groups by reaction of the compound that contains the hydroxy group with acid and an alkylcarboxylic acid such as acetic acid, or with acid and an arylcarboxylic acid such as benzoic acid. In the case of compounds containing carboxylic acid groups, the pharmaceutically acceptable esters are prepared from compounds containing the carboxylic acid groups by reaction of the compound with base such as triethylamine and an alkyl halide, for example with methyl iodide, benzyl iodide, cyclopentyl iodide or alkyl triflate. They also can be prepared by reaction of the compound with an acid such as hydrochloric acid and an alcohol such as ethanol or methanol.
The term “pharmaceutically acceptable amide” refers to non-toxic amides of the present disclosure derived from ammonia, primary C 1 -to-C 6 alkyl amines and secondary C 1 -to-C 6 dialkyl amines. In the case of secondary amines, the amine can also be in the form of a 5- or 6-membered heterocycle containing one nitrogen atom. Amides derived from ammonia, C 1 -to-C 3 alkyl primary amides and C 1 -to-C 2 dialkyl secondary amides are preferred. Amides of disclosed compounds can be prepared according to conventional methods. Pharmaceutically acceptable amides can be prepared from compounds containing primary or secondary amine groups by reaction of the compound that contains the amino group with an alkyl anhydride, aryl anhydride, acyl halide, or aroyl halide. In the case of compounds containing carboxylic acid groups, the pharmaceutically acceptable amides are prepared from compounds containing the carboxylic acid groups by reaction of the compound with base such as triethylamine, a dehydrating agent such as dicyclohexyl carbodiimide or carbonyl diimidazole, and an alkyl amine, dialkylamine, for example with methylamine, diethylamine, and piperidine.

In an embodiment of the present disclosure, the active agent can be administered to the subject using any means capable of resulting in the desired effect. Thus, the active agent can be incorporated into a variety of formulations for therapeutic administration. For example, the active agent can be formulated into pharmaceutical compositions by combination with appropriate, pharmaceutically acceptable carriers or diluents, and may be formulated into preparations in solid, semi-solid, liquid or gaseous forms, such as tablets, capsules, powders, granules, ointments, solutions, suppositories, injections, inhalants and aerosols.
In pharmaceutical dosage forms, the active agent may be administered in the form of its pharmaceutically acceptable salts, or a subject active composition may be used alone or in appropriate association, as well as in combination, with other pharmaceutically active compounds. The following methods and excipients are merely exemplary and are in no way limiting.
For oral preparations, the active agent can be used alone or in combination with appropriate additives to make tablets, powders, granules or capsules, for example, with conventional additives, such as lactose, mannitol, corn starch or potato starch; with binders, such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators, such as corn starch, potato starch or sodium carboxymethylcellulose; with lubricants, such as talc or magnesium stearate; and if desired, with diluents, buffering agents, moistening agents, preservatives and flavoring agents.
Embodiments of the active agent can be formulated into preparations for injection by dissolving, suspending or emulsifying them in an aqueous or nonaqueous solvent, such as vegetable or other similar oils, synthetic aliphatic acid glycerides, esters of higher aliphatic acids or propylene glycol; and if desired, with conventional additives such as solubilizers, isotonic agents, suspending agents, emulsifying agents, stabilizers and preservatives.
Embodiments of the active agent can be utilized in aerosol formulation to be administered via inhalation. Embodiments of the active agent can be formulated into pressurized acceptable propellants such as dichlorodifluoromethane, propane, nitrogen and the like.
Furthermore, embodiments of the active agent can be made into suppositories by mixing with a variety of bases such as emulsifying bases or water-soluble bases. Embodiments of the active agent can be administered rectally via a suppository. The suppository can include vehicles such as cocoa butter, carbowaxes and polyethylene glycols, which melt at body temperature, yet are solidified at room temperature.
Unit dosage forms for oral or rectal administration, such as syrups, elixirs, and suspensions, may be provided wherein each dosage unit, for example, teaspoonful, tablespoonful, tablet or suppository, contains a predetermined amount of the composition containing one or more compositions. Similarly, unit dosage forms for injection or intravenous administration may comprise the active agent in a composition as a solution in sterile water, normal saline or another pharmaceutically acceptable carrier.
Embodiments of the active agent can be formulated in an injectable composition in accordance with the disclosure. Typically, injectable compositions are prepared as liquid solutions or suspensions; solid forms suitable for solution in, or suspension in, liquid vehicles prior to injection may also be prepared. The preparation may also be emulsified or the active ingredient (triamino-pyridine derivative and/or the labeled triamino-pyridine derivative) encapsulated in liposome vehicles in accordance with the present disclosure.
In an embodiment, the active agent can be formulated for delivery by a continuous delivery system. The term “continuous delivery system” is used interchangeably herein with “controlled delivery system” and encompasses continuous (e.g., controlled) delivery devices (e.g., pumps) in combination with catheters, injection devices, and the like, a wide variety of which are known in the art.
Mechanical or electromechanical infusion pumps can also be suitable for use with the present disclosure. Examples of such devices include those described in, for example, U.S. Pat. Nos. 4,692,147; 4,360,019; 4,487,603; 4,360,019; 4,725,852; 5,820,589; 5,643,207; 6,198,966; and the like. In general, delivery of the active agent can be accomplished using any of a variety of refillable, pump systems. Pumps provide consistent, controlled release over time. In some embodiments, the active agent can be in a liquid formulation in a drug-impermeable reservoir, and is delivered in a continuous fashion to the individual.
In one embodiment, the drug delivery system is an at least partially implantable device. The implantable device can be implanted at any suitable implantation site using methods and devices well known in the art. An implantation site is a site within the body of a subject at which a drug delivery device is introduced and positioned. Implantation sites include, but are not necessarily limited to, a subdermal, subcutaneous, intramuscular, or other suitable site within a subject's body. Subcutaneous implantation sites are used in some embodiments because of convenience in implantation and removal of the drug delivery device.
Drug release devices suitable for use in the disclosure may be based on any of a variety of modes of operation. For example, the drug release device can be based upon a diffusive system, a convective system, or an erodible system (e.g., an erosion-based system). For example, the drug release device can be an electrochemical pump, osmotic pump, an electroosmotic pump, a vapor pressure pump, or osmotic bursting matrix, e.g., where the drug is incorporated into a polymer and the polymer provides for release of drug formulation concomitant with degradation of a drug-impregnated polymeric material (e.g., a biodegradable, drug-impregnated polymeric material). In other embodiments, the drug release device is based upon an electrodiffusion system, an electrolytic pump, an effervescent pump, a piezoelectric pump, a hydrolytic system, etc.
Drug release devices based upon a mechanical or electromechanical infusion pump can also be suitable for use with the present disclosure. Examples of such devices include those described in, for example, U.S. Pat. Nos. 4,692,147; 4,360,019; 4,487,603; 4,360,019; 4,725,852, and the like. In general, a subject treatment method can be accomplished using any of a variety of refillable, non-exchangeable pump systems. Pumps and other convective systems are generally preferred due to their generally more consistent, controlled release over time. Osmotic pumps are used in some embodiments due to their combined advantages of more consistent controlled release and relatively small size (see, e.g., PCT published application no. WO 97/27840 and U.S. Pat. Nos. 5,985,305 and 5,728,396). Exemplary osmotically-driven devices suitable for use in the disclosure include, but are not necessarily limited to, those described in U.S. Pat. Nos. 3,760,984; 3,845,770; 3,916,899; 3,923,426; 3,987,790; 3,995,631; 3,916,899; 4,016,880; 4,036,228; 4,111,202; 4,111,203; 4,203,440; 4,203,442; 4,210,139; 4,327,725; 4,627,850; 4,865,845; 5,057,318; 5,059,423; 5,112,614; 5,137,727; 5,234,692; 5,234,693; 5,728,396; and the like.
In some embodiments, the drug delivery device is an implantable device. The drug delivery device can be implanted at any suitable implantation site using methods and devices well known in the art. As noted herein, an implantation site is a site within the body of a subject at which a drug delivery device is introduced and positioned. Implantation sites include, but are not necessarily limited to a subdermal, subcutaneous, intramuscular, or other suitable site within a subject's body.
In some embodiments, the active agent can be delivered using an implantable drug delivery system, e.g., a system that is programmable to provide for administration of the agent. Exemplary programmable, implantable systems include implantable infusion pumps. Exemplary implantable infusion pumps, or devices useful in connection with such pumps, are described in, for example, U.S. Pat. Nos. 4,350,155; 5,443,450; 5,814,019; 5,976,109; 6,017,328; 6,171,276; 6,241,704; 6,464,687; 6,475,180; and 6,512,954. A further exemplary device that can be adapted for the present disclosure is the Synchromed infusion pump (Medtronic).
Suitable excipient vehicles for the active agent are, for example, water, saline, dextrose, glycerol, ethanol, or the like, and combinations thereof. In addition, if desired, the vehicle may contain minor amounts of auxiliary substances such as wetting or emulsifying agents or pH buffering agents.

See, e.g., Remington's Pharmaceutical Sciences, Mack Publishing Company, Easton, Pennsylvania, 17th edition, 1985. The composition or formulation to be administered will, in any event, contain a quantity of the active agent adequate to achieve the desired state in the subject being treated.
Compositions of the present disclosure can include those that comprise a sustained-release or controlled release matrix. In addition, embodiments of the present disclosure can be used in conjunction with other treatments that use sustained-release formulations. As used herein, a sustained-release matrix is a matrix made of materials, usually polymers, which are degradable by enzymatic or acid-based hydrolysis or by dissolution. Once inserted into the body, the matrix is acted upon by enzymes and body fluids. A sustained-release matrix desirably is chosen from biocompatible materials such as liposomes, polylactides (polylactic acid), polyglycolide (polymer of glycolic acid), polylactide co-glycolide (copolymers of lactic acid and glycolic acid), polyanhydrides, poly(ortho)esters, polypeptides, hyaluronic acid, collagen, chondroitin sulfate, carboxcylic acids, fatty acids, phospholipids, polysaccharides, nucleic acids, polyamino acids, amino acids such as phenylalanine, tyrosine, isoleucine, polynucleotides, polyvinyl propylene, polyvinylpyrrolidone and silicone. Illustrative biodegradable matrices include a polylactide matrix, a polyglycolide matrix, and a polylactide co-glycolide (co-polymers of lactic acid and glycolic acid) matrix.
In another embodiment, the pharmaceutical composition of the present disclosure (as well as combination compositions) can be delivered in a controlled release system. For example, the active agent may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. In one embodiment, a pump may be used (Sefton (1987). CRC Crit. Ref. Biomed. Eng. 14:201; Buchwald et al. (1980). Surgery 88:507; Saudek et al. (1989). N. Engl. J. Med. 321:574). In another embodiment, polymeric materials are used. In yet another embodiment a controlled release system is placed in proximity of the therapeutic target thus requiring only a fraction of the systemic dose. In yet another embodiment, a controlled release system is placed in proximity of the therapeutic target, thus requiring only a fraction of the systemic. Other controlled release systems are discussed in the review by Langer (1990). Science 249:1527-1533.
In another embodiment, the compositions of the present disclosure (as well as combination compositions separately or together) include those formed by impregnation of the active agent described herein into absorptive materials, such as sutures, bandages, and gauze, or coated onto the surface of solid phase materials, such as surgical staples, zippers and catheters to deliver the compositions. Other delivery systems of this type will be readily apparent to those skilled in the art in view of the instant disclosure.
Embodiments of the active agent can be administered to a subject in one or more doses. Those of skill will readily appreciate that dose levels can vary as a function of the specific the active agent administered, the severity of the symptoms and the susceptibility of the subject to side effects. Preferred dosages for a given compound are readily determinable by those of skill in the art by a variety of means.
In an embodiment, multiple doses of the active agent are administered. The frequency of administration of the active agent can vary depending on any of a variety of factors, e.g., severity of the symptoms, and the like. For example, in an embodiment, the active agent can be administered once per month, twice per month, three times per month, every other week (qow), once per week (qw), twice per week (biw), three times per week (tiw), four times per week, five times per week, six times per week, every other day (qod), daily (qd), twice a day (qid), or three times a day (tid). As discussed above, in an embodiment, the active agent is administered continuously.
The duration of administration of the active agent, e.g., the period of time over the active agent is administered, can vary, depending on any of a variety of factors, e.g., patient response, etc. For example, the active agent in combination or separately, can be administered over a period of time of about one day to one week, about two weeks to four weeks, about one month to two months, about two months to four months, about four months to six months, about six months to eight months, about eight months to 1 year, about 1 year to 2 years, or about 2 years to 4 years, or more.
Dosage at concentrations as high as 60 micrograms/kilograms that are non-toxic. Also lower concentrations, such as 1-4 micrograms/kilogram, show biological activity in in vivo systems. The concentration in in vitro established at 10−9-10−6 M are active and this concentration is expected to be achieved in the cell environment.

In brief, Example 1 describes molecular docking-based virtual screening studies predict that novel vitamin D and related lumisterol hydroxymetabolites are able to bind to the active sites of two SARS-CoV-2 transcription machinery enzymes with high affinity. These enzymes are the main protease (MP9 and RNA dependent RNA polymerase (RdRP) which play important roles in viral replication and establishing infection. Based on predicted binding affinities and specific interactions, we identified ten D3 and lumisterol analogs as likely binding partners of SARS-CoV-2 Mpro and RdRP and therefore tested their ability to inhibit these enzymes. Activity measurements demonstrated that 25(OH)L3, 24(OH)L3 and 20(OH)7DHC are the most effective of the hydroxymetabolites tested at inhibiting the activity of SARS-CoV-2 Mpro, causing 10-19% inhibition. These same derivatives as well as other hydroxylumisterols and hydroxyvitamin D3 metabolites inhibited RdRP by 50-60%. Thus, inhibition of these enzymes by vitamin D and lumisterol metabolites may provide a novel approach to hindering the SARS-CoV-2 infection.
In brief, Example 2 describes that active hydroxyl-forms of vitamin D are anti-inflammatory, induce anti-oxidative responses, and stimulate innate immunity against infectious agents. These properties are shared by calcitriol and the CYP11A1-generated non-calcemic hydroxyderivatives. They inhibit the production of pro-inflammatory cytokines, downregulate NF-κB, show inverse agonism on RORγ and counteract oxidative stress through the activation of NRF-2. Therefore, a direct delivery of hydroxyderivatives of vitamin D deserves consideration in the treatment of COVID-19 or ARDS of different etiology. We also recommend treatment of COVID-19 patients with high dose vitamin D since populations most vulnerable to this disease are likely vitamin D deficient and patients are already under supervision in the clinics. We hypothesize that different routes of delivery (oral and parenteral) will have different impact on the final outcome

The Coronavirus disease 2019 (COVID-19) pandemic has brought tremendous socio-economic losses, causing great adversity with some intriguing and complex scientific questions to be answered. The variations in mortality and severity of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected patients in different regions of the world is a challenging conundrum that still remains unanswered. A plethora of reports has made a striking and intriguing co-relation that vitamin D deficiency influences the risk of mortality in SARS-CoV-2 infected patients [1]. Vitamin D is a pleotropic hormone, which exerts genomic and non-genomic effects on expression of a large number of genes that modify many important biological functions [2]. The genomic effects initially involve the binding of 1,25(OH) 2 D3 (1,25-dihydroxyvitamin D3) to the VDR (vitamin D receptor). The ligand-based activation of this nuclear transcription factor can modulate the expression of genes positively or negatively. However, a variety of signaling pathways can be activated in a non-genomic manner by 1,25(OH)2D3 [2]. Multiple mechanisms have been proposed by which vitamin D protects against infection and reduces mortality when present in sufficient physiological levels [3-5]. Vitamin D modulates the innate and adaptive immune response [6] and hence vitamin D deficiency is a recognized risk factor for the cytokine storm and ARDS (Acute respiratory distress syndrome) (reviewed in [7, 8]). Vitamin D also has been reported to affect the expression of ACE2 and TMPRSS2, membrane receptors responsible for the cellular entry of the virus [9]. In addition, active forms of vitamin D can regulate the expression of the antiviral pathways and also viral load in the system, when used at high concentrations [5, 10]. However, as of 2021, there has been only one report confirming a direct relationship between vitamin D and inhibition of the SARS-CoV-2 viral replication where it was shown that calcitriol (1,25(OH)2D3) reduces the viral
load in the CPE (Cytopathogenic effect) assay [11]. Although the authors did not provide the mechanism behind this action, their study indicates that active forms of vitamin D3 (D3) may have the potential to inhibit or neutralize SARS-CoV-2 growth and reduce the severity of the infection.
The exposure of skin to ultraviolet radiation (UVB) leads to conversion of 7DHC to previtamin D3 (pre-D3) which then undergoes thermal isomerization to form D3 [6, 12]. With a high UVB dose, pre-D3 undergoes photoisomerization to lumisterol (L3) and tachysterol (T3). T3, being the most photoreactive product, undergoes UVB-driven conversion to L3 via pre-D3. The resulting product, L3, is the major photoisomer observed in skin after prolonged UVB
exposure [13]. Traditionally, only D3 was regarded as the important biological regulator from these photochemical reactions, while L3 was considered to not affect calcium metabolism nor
display any other significant biological activity [14]. It was postulated that transformation of pre-D3 into metabolically inactive L3 explained why UVB-induced cutaneous production of pre-D3
does not lead to systemic D3 intoxication [12]. It is now apparent that this assumption is erroneous since new CYP11A1- and CYP27A1-dependant pathways of hydroxylation of L3 have been discovered with the products such as 20(OH)L3, 22(OH)L3, 24(OH)L3 and 25(OH)L3 displaying biological activity [14-17]. CYP11A1-mediated pathways of of both L3 and vitamin D metabolism have been shown to occur in vivo with their products having phenotypic/biological activities determined by their structures and cellular targets [14].
To evaluate whether these novel L3 and D3 hydroxyderivatives possess anti-viral potential, we screened them for effects on viral replication and transcription machinery proteins that are the most promising drug targets against SARS-CoV-2. The proteins tested in the study were RNA-dependent RNA polymerase (RdRP or nsp12) and 3C-like protease (3CLP r° or Mpro). SARS-CoV-2 contains a —30-kb RNA genome encoding two large overlapping polyprotein precursors (pp1a and pp1ab), four structural proteins (spike, envelope, membrane, and nucleocapsid), and several accessory proteins [18, 19]. It is essential for SARS-CoV-2 replication that the two polyproteins (pp1a/pp1ab) be cleaved into individual nonstructural proteins. Mpro exclusively cleaves polypeptides after a glutamine (Gin) residue and no other human protease have the same cleavage specificity as Mpro [19, 20]. This critical function of SARS-CoV-2 Mpro in replication and transcriptional regulation has made it a prime target for drug discovery purposes [18, 19]. It shows a 96% similarity at the amino acid sequence level with SARS-CoV Mpro [20, 21]. RdRP is another conserved protein of retroviruses and is also a
proven target for the development of antiviral drugs [22]. RdRP has two binding sites for ligands, one is the active site which binds nucleoside inhibitors (NIs) and the other is an alosteric site that binds non-nucleoside inhibitors (NNIs). Remdesivir mimics a nucleoside triphosphate substrate for the polymerase becoming covalently linked to the replicating RNA which interferes with further synthesis of the RNA [23].
In this example, we used a systematic approach for structure-based drug discovery in the search for potential therapeutic candidates from a pool of vitamin D and lumiterol metabolites, targeting the SARS-CoV-2 replication machinery enzymes Mpro and RdRP. Structure-based virtual screening was used to predict analogs that could bind to these two proteins followed by enzyme inhibition studies to confirm these interactions.
Methods of production of the compounds tested in this study and their structures are described in Table S1.
In this study, a systematic in silico approach was utilized using a number of bioinformatics software, such as MGL AutoDock Tools [22], AutoDock Vina and Discovery Studio Visualizer [24]. The three-dimensional coordinates of SARS-CoV-2 Mpro and RdRP were retrieved from the RCSB Protein Data Bank (PDB). The structure of SARS-CoV-2 Mpro in complex with a Michael acceptor inhibitor known as N3 provides a basis to design high-affinity
inhibitors with improved pharmacological properties [17]. The atomic coordinates of SARS-CoV-2 Mpro were taken from the PDB (ID: 6LU7) for molecular docking-based virtual screening. The structural coordinates of SARS-CoV-2 RdRP in apo form and in complex with Remdesivir were taken from the PDB (ID: 7BV1 and 7BV2, respectively). The structure was prepared by removing co-crystallized inhibitors and adding hydrogens, and assigning appropriate atom types. AutoDock Vina was used to carry out molecular docking, where the search space was structurally blind for all the compounds with default docking parameters. High-affinity compounds were selected, and their docked conformations were generated for analyzing their possible interaction towards SARS-CoV-2 Mpro and RdRP. Only those compounds which specifically interact with the critical residues of the binding pockets of SARS-CoV-2 Mpro and RdRP were selected from the interaction analysis.
The SARS-CoV-2 3CLPro (Mpro), MBP-tagged Assay Kit (BPS Biosciences, San Diego, CA, USA) was used to measure 3CL Protease (Mpro) activity for screening and profiling applications. The 3CL inhibitor GC376 was included as a positive control and also used as a standard. The assay was performed according to the protocol provided by the manufacturer with the concentration of compounds tested being 10−7 M.
The assay for RdRP activity was outsourced to BPS Biosciences (San Jose, California, USA) using the following protocol. Dilutions of the compounds tested were prepared in assay buffer containing 5% ethanol, then 2 μl of this was added to the reaction mix to give a final volume of 10 μl, thus making the final ethanol concentration 1% in all reactions (controls without compounds similarly contained 1% ethanol). The RdRP reactions were performed in triplicate at 37° C. for 60 min in a 10 μl mixture containing assay buffer, RNA duplex, ATP substrate and enzyme, and the test compound. The reactions were carried out in wells of 384-well Optiplate (PerkinElmer). After enzymatic reactions, 10 μl of anti-Dig Acceptor beads (PerkinElmer, diluted 1:500 with lx detection buffer) were added to the reaction mix. After brief shaking, the plate was incubated for 30 min. Finally, 10 μl of AlphaScreen Streptavidin-conjugated donor beads (Perkin, diluted 1:125 with lx detection buffer) were added. After 30 min, the samples were measured using an AlphaScreen microplate reader (EnSpire Alpha 2390 Multilabel Reader, Perkin Elmer). The values of % activity versus the concentrations of the compound tested were then plotted using non-linear regression analysis of a Sigmoidal dose-response curve generated with the equation Y=B+(T−B)/1+10((LogEC50−X)×Hill Slope), where Y=percent activity, B=minimum percent activity, T=maximum percent activity, X=logarithm of compound and Hill Slope=slope factor or Hill coefficient. The IC50 value was determined as the concentration causing half-maximal activity.
Structure-based virtual screening of an in-house library of D3, L3 and 7DHC analogs was performed to search for high-affinity binding partners of SARS-CoV-2 Mpro and RdRP that
could be used in the design of potential therapeutics against COVID-19 [24]. We first calculated the binding affinities of the available compounds in the library when bound to SARS-CoV-2 pro and RdRP, and then performed interaction analysis to identify better hits. Based on the specific interaction, we identified a set of ten D3, L3 and 7DHC derivatives out of 35 compounds tested that had substantial affinity and specific interactions with the active site pocket of SARS-CoV-2 Mpro and RdRP (Table 1a & 1b). The predicted binding affinities of the 10 compounds compared well with those of recognized anti-virals, Danoprevir, Lopinavir and Ritonavir (Table 1a & 1b).
A detailed analysis of all the docked conformers of the top ten hits was performed to find compounds binding specifically to the SARS-CoV-2 Mpro and RdRP substrate-binding pockets (
Similar to Mpro molecular docking, we selected top 10 hits based on interaction with the SARS-CoV-2 RdRP active site pocket, from which we identified seven compounds that form interactions with a set of critically essential residues of SARS-CoV-2 RdRP. The residues Lys545, Arg555, Asp623, Ser682, Thr687, Asn691, Ser759, Asp760, and Asp761 of SARS-CoV-2 in RdRP substrate binding pocket that interact with Remdesivir, also offered a significant number of interactions with each of the seven compounds (
The binding data predict that the selected sterols and secosteroids are likely to function as inhibitors of Mpro and RdRP enzyme activity and potentially serve as therapeutics against
COVID-19. Consistent with this prediction, we found that the compounds inhibited Mpro enzyme activity using the 3CL Protease, MBP-tagged (SARS-CoV-2) Assay kit (
RdRP catalyzes the replication of RNA from an RNA template and it is known that SARS-CoV-2 RdRP only functions when all three subunits are present (nsp12, nsp7 & nsp8). Hence, establishing the assay to measure its activity was difficult so this was outsourced to BPS biosciences who had already developed an in-house assay to measure enzyme activity. Although, the inhibition of RdRP activity did not precisely reflect the pattern of docking energies, all of the compounds tested exhibited inhibitory activity ranging from 40-60% at a concentration of 2×10−7 M (
Overall, these results provide strong support for the ability of D3, L3 and 7DHC hydroxy-metabolites to reduce the viral load in infected cells or the blood stream. A deficiency of these hydroxyometabolites may play a vital role in enabling the transition of SARS-CoV-2 patients from becoming asymptomatic to symptomatic. For Mpro, 25(OH)D3, the major form of vitamin D3 present in blood, significant inhibition was observed at a concentration of 100 nM which compares to a plasma concentration in non-deficient people typically between 50 to 100 nM [15]. For RdRP, the IC50 for 25(OH)D3 was 1.3 μM, approximately one order of magnitude above its plasma concentration. For the hydroxylumisterols tested, plasma concentrtions are
unknown except for 20(OH)L3 where a value of 25 nM has been reported [17], but based on the enzymology, 25(OH)L3 which had the lowest IC50 (0.5 μM) for inhibition of RdRP, is likely to be substantially higher [15].
A plethora of reports strongly suggests that vitamin D plays a vital role in protection against SARS-COV-2 which includes preventing infected patients from developing severe disease. Here, we report for the first time that a range of vitamin D3 related compounds, including 7DHC and L3 hydroxyderivaties, display anti-SARS-CoV-2 activities of and we provide a possible target on which they may act directly. Vaccines against SARS-CoV-2 are clearly a major advance in controlling COVID-19, however, new viral variants emphasize the need for alternative therapeutic approaches. This study presents novel vitamin D and L3 metabolites as candidates for anti-viral drugs.
The COVID-19 is currently the foremost health issue in the world. SARS-CoV-2 (severe acute respiratory syndrome coronavirus) is an enveloped positive strain RNA virus in the family Coronaviridae, which also includes the virus SARS-CoV-1 (which was another outbreak in 2002-2003) 1 . COVID-19 has a fatality rate up to —5%, which is several times higher than influenza2,3. The leading cause of death in the patients is due to acute respiratory distress syndrome (ARDS) 2 induced by proinflammatory responses and oxidative stress (
Vitamin D is a fat-soluble prohormone, which after production in the skin or oral delivery affects important physiological functions in the body including regulation of the innate and adaptive immunity 4-6 . Vitamin D can be activated through canonical and non-canonical pathways (
An alternative pathway of vitamin D activation by CYP11A1 leads to production of more than 10 metabolites some of which are non-calcemic even at high doses5,10,11. These hydroxyderivatives, including 20(OH)D3 and 20,23(OH)2D3,l are produced in humans12-15. In addition, 20(OH)D3 has been detected in the honey, which defines it as a natural product16. CYP11A1 is expressed not only in adrenals, placenta and gonads but also in immune cells and other peripheral organs17.
Both 1,25(OH)2D 3 and non-calcemic CYP11A1 derived metabolites use various, although partially overlapping, mechanisms in enacting their anti-inflammatory and anti-oxidative effects (
The non-calcemic CYP11A1-derived vitamin D compounds also have their own methods to fight inflammation (
A leading cause of ARDS is “cytokine storm”, a hyperactive immune response triggered by the viral infection (
Oxidative stress is also involved in the development of ARDS through action of reactive oxygen species (ROS) and nitrogen species (NRS)31-33. The production of ROS and RNS can be triggered by pathogens promoting the secretion of cytokines, which stimulate ROS production thereby producing a positive feedback loop (
There is a strong experimental evidence that active forms of vitamin D including the classical 1,25(OH)2D3, and novel CYP11A1-derived hydroxyderivatives8,11 exert potent anti-inflammatory activities including inhibition of IL-1, IL-6, IL-17, TNFα and INFγ production or other proinflammatory pathways (Supplemental table 1)11,18,20,37,38. The mechanism of action includes downregulation of NF-κB involving action on VDR and inverse agonism on RORγ leading to attenuation of Th17 responses (
Low vitamin D status in winter permits viral epidemics and vitamin D supplementation could reduce the incidence, severity, and risk of viral diseases42-46. In addition, several reports have found a strong association between vitamin D deficiency/insufficiency and enhanced COVID-19 severity and mortality46-63 with the most recent study defining low plasma 25(OH)D3 as an independent risk factor for COVID-19 infection and hospitalization54. Therefore, we retrospectively analyzed microarray data of human epithelial cells treated with 20,23(OH)2D3 and 1,25(OH)2D324. We found the downregulation of pathways connected with influenza infection and viral RNA transcription, translation, replication, life cycle and of subject interactions with influenza factors with 20,23(OH)2D3 expressing higher anti-viral potency (Table 1).
While 1,25(OH)2D3 has the limitation imposed by the toxicity that includes hypercalcemia7,9, CYP11A1-derived 20(OH)D3, 20(OH)D2 and 20,23(OH)2D3 are not toxic and non-calcemic at very high doses (3-60 μg/kg) at which 1,25(OH)2D3 and 25(OH)D3 are calcemic55-59.
The hyperinduction of proinflammatory cytokines production (cytokine storm), further magnified by oxidative stress induced by the viral infection or cytokines themselves, acting reciprocally in self-amplifying circuitry, gradually damage/destroy the affected organs leading to death in the severe cases of COVID-19 infection (
As relates to the vitamin D precursor it is reasonable to propose that patients being admitted with COVID-19 infection to receive as soon as possible 200,000 IU of vitamin D2 or vitamin D3 followed by 4,000-10,000 IU/day, if justifiable46,66. Vitamin D3 at 200,000 IU orally has been used to attenuate inflammatory responses induced by the sunburn66. It must be noted that application of 250,000-500,000 IU of vitamin D was reported be safe in critically ill patients and was associated with decreased hospital length of stay and improved ability of the blood to carry oxygen (reviewed in67,68)
Different routes of delivery of vitamin D precursor can have a profound effect on the final panel of circulating in the body vitamin D derivatives (
Since vitamin D is readily available, easy to use and relatively nontoxic, it can represent an immediate solution to the problems at relatively high doses, since populations most vulnerable to negative outcome of COVID-19 disease are likely vitamin D deficient and the patients are already under supervision in the hospital environment and are monitored for adverse effects. Vitamin D toxicity is typically not observed until extremely high doses of vitamin D in the range of 50,000-100,000 !Us daily for several months or years71. Doses up to 500,000 IUs have been routinely given to nursing home patients twice a year in Scandinavian countries to reduce risk for fracture without any evidence of vitamin D intoxication including hypercalcemia, hyperphosphatemia and soft tissue calcification71.
In addition, we believe that routes of delivery are likely to impact the final outcome, because bypassing liver vitamin D3 will also be accessible to CYP11A1 for metabolism in organs expressing this enzyme.
