BACKGROUND OF THE INVENTION
RIG-I like receptors (RLRs) are a type of intracellular pattern recognition receptor involved in the detection of viruses by the innate immune system. RLRs are critical sentinels of viral infection, surveying the cytosol of all mammalian cell types for the presence of viruses containing RNA genomes. In addition, RLRs play a role in autoimmunity. Factors induced by RLRs are responsible for activating autoreactive T-cells, and as such, RLRs have emerged as important regulators for a growing list of non-infectious immunopathologies resulting from inappropriate host response to self RNA. Thus, depending on the clinical symptoms, some patients will benefit from inhibition of the RLR signaling pathways (e.g., patients with autoimmune disease) whereas others will benefit from activation of these pathways (e.g., patients suffering from RNA viral infection).
Despite a clinical utility for such therapeutic molecules, few RLR specific inhibitors and activators are currently available. Accordingly, there is a need for developing novel RLR specific inhibitors and activators for treating viral infection and autoimmune disorders.
SUMMARY OF THE INVENTION
As described below, the present invention is based upon the discovery of novel RIG-I like receptor (RLR) specific activators and inhibitors. The invention features compositions and kits containing the novel RLR activators or inhibitors. The invention also features methods for using these novel therapeutic molecules to treat a subject having or at risk of viral infection and/or autoimmune disease.
In aspects, the invention provides RLR inhibitors that inhibit the MAVS adaptor protein.
In embodiments, the RLR inhibitor comprises a polypeptide fragment of the MAVS protein (e.g., human MAVS protein). In related embodiments, the polypeptide fragment is a competitive inhibitor or dominant negative of the MAVS protein.
In embodiments, the RLR inhibitor comprises amino acids 10-77, 15-77, 20-77, 25-77, 30-77, 35-77, 40-77, 45-77, 50-77, 10-73, 15-73, 20-73, 25-73, 30-73, 35-73, 40-73, 45-73, and 50-73. In related embodiments, the RLR inhibitor further comprises amino acids from the PRR (any amino acids from 107-173) and/or the TM (any amino acids from 514-535). In some embodiments, the RLR inhibitor comprises amino acids 50-73 of the MAVS protein (GNRDTLWHLFNTLQRRPGWVEYFI; SEQ ID NO: 1).
In aspects, the invention provides RLR activators that activate the MAVS adaptor protein.
In any of the above aspects and embodiments, the RLR inhibitor or activator further contains a targeting moiety. In embodiments, the targeting moiety facilitates delivery of the RLR inhibitor or activator to the cytosol of a cell. In related embodiments, the targeting moiety contains a cell penetrating domain of the Drosophila antennapedia protein. The cell penetrating domain can contain amino acids RQIKIWFQNRRMKWKK (SEQ ID NO: 2).
In embodiments, the targeting moiety is TAT or Pep-1.
In any of the above aspects and embodiments, the RLR inhibitor or activator further contains a detectable moiety. Detectable moieties are well known in the art and can be detected by spectroscopic, photochemical, biochemical, immunochemical, physical, or chemical means. Exemplary moieties include, but are not limited to, enzymes, fluorescent molecules, particle labels, electron-dense reagents, radiolabels, biotin, digoxigenin, or a hapten or a protein that has been made detectable.
The RLR inhibitor or activator can be covalently or non-covalently linked to a moiety (e.g., targeting moiety and/or detectable moiety). In embodiments, the RLR inhibitor or activator are covalently linked to the moiety. In related embodiments, the covalent linkage of the moiety is N-terminal to the polypeptide fragment. In related embodiments, the covalent linkage of the moiety is C-terminal to the peptide fragment.
In aspects, the invention provides an RLR inhibitor containing GNRDTLWHLFNTLQRRPGWVEYFI (SEQ ID NO: 1). In embodiments, the RLR inhibitor further comprises RQIKIWFQNRRMKWKK (SEQ ID NO: 2).

DEFINITIONS
To facilitate an understanding of the present invention, a number of terms and phrases are defined below.
The terms “RIG-I like receptor” or “RLR” as used herein refer to a family of dsRNA helicase enzymes. There are three members of the RLR family: RIG-I (retinoic acid-inducible gene 1); MDA5 (melanoma differentiation-associated protein 5); and LGP2 (Laboratory of Genetics and Physiology 2; also known as Probable ATP-dependent RNA helicase DHX58 and RIG-1-like receptor 3). These molecules are involved in recognition of viruses by the innate immune system. For example, RIG-I and MDA5 activate MAVS (mitochondrial antiviral-signaling protein; also known as VISA (virus-induced signaling adapter), IPS-1 and Cardif), which triggers antiviral signaling pathways that result in the expression of cytokines, interferons (IFNs) and interferon stimulated genes (ISGs).
The terms “mitochondrial antiviral-signaling protein,” “MAVS,” “VISA,” “virus-induced signaling adapter,” “IPS-1,” and “Cardif” as used herein refer to an intracellular adaptor protein encoded by the MAVS gene. In embodiments, the terms refer to a polypeptide or fragment thereof having at least 85%, 90%, 95%, 99%, or more amino acid identity to NCBI Accession Nos. Q7Z434, Q7Z434.2, and NP_065797.2.
The exemplary sequence at NCBI Accession No. Q7Z434 is (SEQ ID NO: 4):

By “RLR activator,” “RLR specific activator,” and the like are meant an agent that increases the effects associated with RLR activation (e.g., increase in antiviral activity). The increase in RLR activity is relative to a reference (e.g., an untreated control). Such activation can be by about 10%, 25%, 50%, 75% or more. In embodiments, the agent is a MAVS specific activator and enhances the activity of the MAVS protein. MAVS activity can be enhanced by increasing the strength or the time of an effect of MAVS (e.g., increase expression of anti-viral cytokines, IFNs, and ISGs). In related embodiments, the MAVS specific activator is a polypeptide or fragment thereof. The activator can be covalently or 50 noncovalently linked to a moiety. Exemplary moieties can be any moiety well known in the art, including targeting moieties. A “targeting moiety” is a moiety that is capable of enhancing the ability of an agent to be targeted to, to bind with, or to enter a cell. For example, the targeting moiety can facilitate delivery of the activator into the cytosol of a cell. Exemplary moieties also include detectable labels that will allow tracking of the agent.
By “RLR inhibitor,” “RLR specific inhibitor,” and the like are meant an agent that decreases the effects associated with RLR activation (e.g., decrease in autoimmune effects). The decrease in RLR activity is relative to a reference (e.g., an untreated control). Such inhibition can be by about 10%, 25%, 50%, 75% or more. In embodiments, the agent is a MAVS specific inhibitor and decreases the activity of the MAVS protein. MAVS activity can be decreased by decreasing the strength or the time of an effect of MAVS (e.g., decrease activation of autoreactive T-cells). In related embodiments, the MAVS specific inhibitor is a polypeptide or fragment thereof. The inhibitor can be covalently or noncovalently linked to a moiety. Exemplary moieties can be any moiety well known in the art, including targeting moieties. The targeting moiety is capable of enhancing the ability of an agent to be targeted to, to bind with, or to enter a cell. For example, the targeting moiety can facilitate delivery of the inhibitor into the cytosol of a cell. Exemplary moieties also include detectable labels that will allow tracking of the agent.
As used herein, the singular forms “a”, “an”, and “the” include plural forms unless the context clearly dictates otherwise. Thus, for example, reference to “an RLR inhibitor” includes reference to more than one RLR inhibitor.
Unless specifically stated or obvious from context, as used herein, the term “or” is understood to be inclusive.
As used herein, the terms “comprises,” “comprising,” “containing,” “having” and the like can have the meaning ascribed to them in U.S. Patent law and can mean “includes,” “including,” and the like; “consisting essentially of” or “consists essentially” likewise has the meaning ascribed in U.S. Patent law and the term is open-ended, allowing for the presence of more than that which is recited so long as basic or novel characteristics of that which is recited is not changed by the presence of more than that which is recited, but excludes prior art embodiments.
By “activate” is meant an increase in activity, level, or other measurable parameter relative to a reference (i.e., an untreated control). Such activation can be by about 10%, 25%, 50%, 75% or more.
“Administering” is defined herein as a means of providing an agent or a composition containing the agent to a subject in a manner that results in the agent being inside the subject's body. Such an administration can be by any route including, without limitation, oral, transdermal (e.g., vagina, rectum, oral mucosa), by injection (e.g., subcutaneous, intravenous, parenterally, intraperitoneally, intrathecal), or by inhalation (e.g., oral or nasal). Pharmaceutical preparations are, of course, given by forms suitable for each administration route.
By “agent” is meant any small molecule chemical compound, antibody, nucleic acid molecule, or polypeptide, or fragments thereof.
By “analog” is meant a molecule that is not identical, but has analogous functional or structural features. For example, an amide, ester, carbamate, carbonate, ureide, or phosphate analog of an RLR activator or inhibitor is a molecule that either: 1) does not destroy the biological activity of the RLR activator or inhibitor and confers upon that RLR activator or inhibitor advantageous properties in vivo, such as uptake, duration of action, or onset of action; or 2) is itself biologically inactive but is converted in vivo to a biologically active compound. Analogs include prodrug forms of an RLR activator or inhibitor. Such a prodrug is any compound that when administered to a biological system generates the RLR activator or inhibitor as a result of spontaneous chemical reaction(s), enzyme catalyzed chemical reaction(s), and/or metabolic chemical reaction(s).
By “control” is meant a standard or reference condition.
The term “derivative” means a pharmaceutically active compound with equivalent or near equivalent physiological functionality to a given agent (e.g., an RLR activator or inhibitor). As used herein, the term “derivative” includes any pharmaceutically acceptable salt, ether, ester, prodrug, solvate, stereoisomer including enantiomer, diastereomer or stereoisomerically enriched or racemic mixture, and any other compound which upon administration to the recipient, is capable of providing (directly or indirectly) such a compound or an antivirally active metabolite or residue thereof.
By “disease” is meant any condition or disorder that damages or interferes with the normal function of a cell, tissue, or organ.
By “enhances” or “increases” is meant a positive alteration of at least about 10%, 25%, 50%, 75%, or 100% relative to a reference.
By “fragment” is meant a portion of a polypeptide or nucleic acid molecule. This portion contains at least 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, or 90% of the entire length of the reference nucleic acid molecule or polypeptide. A fragment may contain 10, 20, 30, 40, 50, 60, 70, 80, 90, or 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000 nucleotides or amino acids.
By “inhibit” is meant a reduction in activity, level, or other measurable parameter relative to a reference (i.e., an untreated control). Such inhibition need not be complete, but can be by about 10%, 25%, 50%, 75% or more.
By “isolated polynucleotide” is meant a nucleic acid (e.g., a DNA) that is free of the genes which, in the naturally-occurring genome of the organism from which the nucleic acid molecule of the invention is derived, flank the gene. The term therefore includes, for example, a recombinant DNA that is incorporated into a vector; into an autonomously replicating plasmid or virus; or into the genomic DNA of a prokaryote or eukaryote; or that exists as a separate molecule (for example, a cDNA or a genomic or cDNA fragment produced by PCR or restriction endonuclease digestion) independent of other sequences. In addition, the term includes an RNA molecule that is transcribed from a DNA molecule, as well as a recombinant DNA that is part of a hybrid gene encoding additional polypeptide sequence.
By an “isolated polypeptide” is meant a polypeptide of the invention that has been separated from components that naturally accompany it. Typically, the polypeptide is isolated when it is at least 60%, by weight, free from the proteins and naturally-occurring organic molecules with which it is naturally associated. In embodiments, the preparation is at least 75%, at least 90%, or at least 99%, by weight, a polypeptide of the invention. An isolated polypeptide of the invention may be obtained, for example, by extraction from a natural source, by expression of a recombinant nucleic acid encoding such a polypeptide; or by chemically synthesizing the protein. Purity can be measured by any appropriate method, for example, column chromatography, polyacrylamide gel electrophoresis, HPLC analysis, and the like.
“Pharmaceutically acceptable” refers to approved or approvable by a regulatory agency of the Federal or a state government or listed in the U.S. Pharmacopeia or other generally recognized pharmacopeia for use in animals, including humans.
“Pharmaceutically acceptable excipient, carrier or diluent” refers to an excipient, carrier or diluent that can be administered to a subject, together with an agent, and which does not destroy the pharmacological activity thereof and is nontoxic when administered in doses sufficient to deliver a therapeutic amount of the agent.
A “pharmaceutically acceptable salt” of an RLR activator or inhibitor recited herein is an acid or base salt that is generally considered in the art to be suitable for use in contact with the tissues of human beings or animals without excessive toxicity, irritation, allergic response, or other problem or complication. Such salts include mineral and organic acid salts of basic residues such as amines, as well as alkali or organic salts of acidic residues such as carboxylic acids. Specific pharmaceutical salts include, but are not limited to, salts of acids such as hydrochloric, phosphoric, hydrobromic, malic, glycolic, fumaric, sulfuric, sulfamic, sulfanilic, formic, toluenesulfonic, methanesulfonic, benzene sulfonic, ethane disulfonic, 2-hydroxyethylsulfonic, nitric, benzoic, 2-acetoxybenzoic, citric, tartaric, lactic, stearic, salicylic, glutamic, ascorbic, pamoic, succinic, fumaric, maleic, propionic, hydroxymaleic, hydroiodic, phenylacetic, alkanoic such as acetic, HOOC—(CH2)n—COOH where n is 0-4, and the like. Similarly, pharmaceutically acceptable cations include, but are not limited to sodium, potassium, calcium, aluminum, lithium and ammonium. Those of ordinary skill in the art will recognize further pharmaceutically acceptable salts for the RLR activators and inhibitors provided herein, including those listed by Remington's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, Pa., p. 1418 (1985). In general, a pharmaceutically acceptable acid or base salt can be synthesized from a parent compound that contains a basic or acidic moiety by any conventional chemical method. Briefly, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in an appropriate solvent.
The term “patient” or “subject” refers to an animal which is the object of treatment, observation, or experiment. By way of example only, a subject includes, but is not limited to, a mammal, including, but not limited to, a human or a non-human mammal, such as a non-human primate, bovine, equine, canine, ovine, or feline.
As used herein, the terms “prevent,” “preventing,” “prevention,” “prophylactic treatment,” and the like, refer to reducing the probability of developing a disease or condition in a subject, who does not have, but is at risk of or susceptible to developing a disease or condition.
By “reduces” is meant a negative alteration of at least about 10%, 25%, 50%, 75%, or 100% relative to a reference.
By “reference” is meant a standard or control condition.
As used herein, the terms “treat,” treating,” “treatment,” and the like refer to reducing or ameliorating a disorder and/or symptoms associated therewith. By “ameliorate” is meant decrease, suppress, attenuate, diminish, arrest, or stabilize the development or progression of a disease. It will be appreciated that, although not precluded, treating a disorder or condition does not require that the disorder, condition or symptoms associated therewith be completely eliminated.
The term “therapeutic effect” refers to some extent of relief of one or more of the symptoms of a disorder or its associated pathology. “Therapeutically effective amount” as used herein refers to an amount of an agent which is effective, upon single or multiple dose administration to the cell or subject, in prolonging the survivability of the patient with such a disorder, reducing one or more signs or symptoms of the disorder, preventing or delaying, and the like beyond that expected in the absence of such treatment. “Therapeutically effective amount” is intended to qualify the amount required to achieve a therapeutic effect. A physician or veterinarian having ordinary skill in the art can readily determine and prescribe the “therapeutically effective amount” (e.g., ED50) of the pharmaceutical composition required. For example, the physician or veterinarian could start doses of the compounds of the invention employed in a pharmaceutical composition at levels lower than that required in order to achieve the desired therapeutic effect and gradually increase the dosage until the desired effect is achieved.
Typically a therapeutically effective dosage should produce a serum concentration of compound of from about 0.1 ng/ml to about 50-100 μg/ml. The pharmaceutical compositions typically should provide a dosage of from about 0.001 mg to about 2000 mg of compound per kilogram of body weight per day. For example, dosages for systemic administration to a human patient can range from 1-10 μg/kg, 20-80 μg/kg, 5-50 μg/kg, 75-150 μg/kg, 100-500 μg/kg, 250-750 μg/kg, 500-1000 μg/kg, 1-10 mg/kg, 5-50 mg/kg, 25-75 mg/kg, 50-100 mg/kg, 100-250 mg/kg, 50-100 mg/kg, 250-500 mg/kg, 500-750 mg/kg, 750-1000 mg/kg, 1000-1500 mg/kg, 1500-2000 mg/kg, 5 mg/kg, 20 mg/kg, 50 mg/kg, 100 mg/kg, 500 mg/kg, 1000 mg/kg, 1500 mg/kg, or 2000 mg/kg. Pharmaceutical dosage unit forms are prepared to provide from about 1 mg to about 5000 mg, for example from about 100 to about 2500 mg of the compound or a combination of essential ingredients per dosage unit form.
The phrase “combination therapy” embraces the administration of an RLR activator or inhibitor and a second therapeutic agent as part of a specific treatment regimen intended to provide a beneficial effect from the co-action of these therapeutic agents. The beneficial effect of the combination includes, but is not limited to, pharmacokinetic or pharmacodynamic co-action resulting from the combination of therapeutic agents. Administration of these therapeutic agents in combination typically is carried out over a defined time period (usually minutes, hours, days, or weeks depending upon the combination selected). “Combination therapy” generally is not intended to encompass the administration of two or more of these therapeutic agents as part of separate monotherapy regimens that incidentally and arbitrarily result in the combinations of the present invention. “Combination therapy” is intended to embrace administration of these therapeutic agents in a sequential manner, that is, wherein each therapeutic agent is administered at a different time, as well as administration of these therapeutic agents, or at least two of the therapeutic agents, in a substantially simultaneous manner. Substantially simultaneous administration can be accomplished, for example, by administering to the subject a single capsule having a fixed ratio of each therapeutic agent or in multiple, single capsules for each of the therapeutic agents. For example, one combination of the present invention comprises an RLR activator or inhibitor and at least one additional therapeutic agent (e.g., an anti-viral agent, an immunosuppressive agent, an anti-inflammatory, and the like) at the same or different times or they can be formulated as a single, co-formulated pharmaceutical composition comprising the two compounds. As another example, a combination of the present invention (e.g., an RLR activator or inhibitor and at least one additional therapeutic agent) is formulated as separate pharmaceutical compositions that can be administered at the same or different time. Sequential or substantially simultaneous administration of each therapeutic agent can be effected by any appropriate route including, but not limited to, oral routes, intravenous routes, intramuscular routes, and direct absorption through mucous membrane tissues (e.g., nasal, mouth, vaginal, and rectal). The therapeutic agents can be administered by the same route or by different routes. For example, one component of a particular combination may be administered by intravenous injection while the other component(s) of the combination may be administered orally. The components may be administered in any therapeutically effective sequence.
The phrase “combination” embraces groups of compounds or non-drug therapies useful as part of a combination therapy.
Unless specifically stated or obvious from context, as used herein, the term “about” is understood as within a range of normal tolerance in the art, for example within 2 standard deviations of the mean. About can be understood as within 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, 0.1%, 0.05%, or 0.01% of the stated value. Unless otherwise clear from context, all numerical values provided herein are modified by the term about.
Ranges provided herein are understood to be shorthand for all of the values within the range. For example, a range of 1 to 50 is understood to include any number, combination of numbers, or sub-range from the group consisting 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50.
The recitation of a listing of chemical groups in any definition of a variable herein includes definitions of that variable as any single group or combination of listed groups. The recitation of an embodiment for a variable or aspect herein includes that embodiment as any single embodiment or in combination with any other embodiments or portions thereof.
Any compositions or methods provided herein can be combined with one or more of any of the other compositions and methods provided herein.



DESCRIPTION OF THE DRAWINGS
FIG. 1 is a schematic showing a novel RLR/MAVS signaling inhibitor. A peptide corresponding to amino acids 50-73 of MAVS (GNRDTLWHLFNTLQRRPGWVEYFI; SEQ ID NO: 1) was synthesized in frame with the cell penetrating domain of the antennapedia protein (RQIKIWFQNRRMKWKK; SEQ ID NO: 2), forming fusion peptide GNRDTLWHLFNTLQRRPGWVEYFI-RQIKIWFQNRRMKWKK (SEQ ID NO: 3). The underlined amino acid is the threonine that is necessary for MAVS signaling.
FIG. 2 includes graphs showing the inhibitory effects of the novel RLR/MAVS signaling inhibitor. The results are from T84 cells that were treated for 1 hr with the inhibitors shown and then treated with PolyIC (PIC) for 5 hours. Cytokine expression was then assessed by qPCR. The y-axis indicates fold induction over untreated cells (UI).
FIG. 3 includes graphs showing anti-viral effects of the novel RLR/MAVS signaling inhibitor. The results are from T84 cells that were pretreated for 1 hr with the inhibitors shown and infected with reovirus for 5 hours. Expression of the cytokines shown was assessed by qPCR. The y-axis indicates induction fold over untreated cells (UI).



DETAILED DESCRIPTION OF THE INVENTION
The invention is based, at least in part, on the discovery of novel RIG-I like receptor (RLR) specific activators and inhibitors. The invention features compositions and kits containing the novel RLR activators or inhibitor. The invention also features methods for using these novel therapeutic molecules to treat a subject having or at risk of viral infection and/or autoimmune disease.
RIG-I Like Receptors
RIG-I like receptors (RLRs) are a family of pattern recognition receptors that are responsible for detecting viral pathogens. RLRs detect pathogen-associated molecular pattern (PAMP) motifs present on viral antigens and initiate a cascade of events that activates the innate immune response. There are three members of the RLR family: RIG-I (retinoic acid-inducible gene 1); MDA5 (melanoma differentiation-associated protein 5); and LGP2 (Laboratory of Genetics and Physiology 2). RIG-I, MDA5, and LGP2 each share a common functional RNA helicase domain near the C terminus (HELICc) that specifically binds to RNA molecules with viral origin. However, two caspase activation and recruitment domains (CARDs) are present at the N terminal region of RIG-I and MDA5, but not LGP2, which trigger the host interferon response via activation of interferon regulatory factor 3 and NFκB.
RIG-I and MDA5 are expressed in all mammalian cells (e.g., immune and nonimmune cells) and provide the only known comprehensive immune-surveillance network operating to detect viral infections. Upon activation (e.g., detection of viral nucleic acids), RIG-I and MDA5 recruit specific intracellular adaptor proteins to initiate signaling pathways that lead to the synthesis of immunomodulatory molecules that are important for eliminating viruses (e.g., cytokines, interferons (IFNs), interferon stimulated genes (ISGs), and the like). One such adaptor protein is mitochondrial antiviral-signaling protein (MAVS).
MAVS is a predicted 57 kDa protein consisting of three functional domains—a single N-terminal CARD domain (10-77 aa), a medial proline-rich region (PRR; 107-173 aa) and a C-terminal transmembrane domain (TM; 514-535 aa) that anchors it to the limiting membranes of mitochondria and peroxisomes. Full MAVS nucleotide and polypeptide sequences, and variants related thereto, are well known in the art. An exemplary nucleotide sequence can be found at NCBI Accession No. NC_000020 (SEQ ID NO: 7):

In addition to sensing viral nucleic acids, RLRs are important regulators of a growing list of non-infectious immunopathologies that result from inappropriate host response to self RNA. For example, the RLR family has been linked genetically to the development of Type 1 Diabetes (TID). The gene encoding MDA5 has been found to be causative for TID (Nejentsev et al., Science 324:387-389 (2009)), as patients that contain loss of function mutations in MDA5 are protected from this disease (Shigemoto et al., J. Biol. Chem. 284:13348-13354 (2009)).
Moreover, it is known that enterovirus infection is linked to T1D. As these viruses are specifically detected by MDA5 (Wang et al., J. Virol. 84:254-260 (2010); von Herrath, M., Nature 459:518-519 (2009)), enteroviral infection of pancreatic beta cells may result in RLR-mediated activation of immune responses that ultimately lead to T1D. Accordingly, RLRs play a role in activating autoreactive T-cells and RLR signaling can be deleterious in the context of autoimmunity.
RLR Activators and Inhibitors
In general, the invention features novel RLR activators and inhibitors that are useful in treating or preventing viral infection or autoimmune disorders. The RLR activators and inhibitors can be any agent (e.g., a small molecule chemical compound, antibody, nucleic acid molecule, or polypeptide) that increases or decreases the effects associated with RLR activation. In embodiments, the RLR activators and inhibitors are MAVS specific activators and inhibitors. In preferred embodiments, the MAVS specific activator or inhibitor is a polypeptide or polypeptide fragment. In related embodiments, the MAVS specific inhibitor is a polypeptide fragment that is a competitive inhibitor or dominant negative of the MAVS protein.
In aspects, the invention provides RLR inhibitors that inhibit the MAVS adaptor protein.
In embodiments, the RLR inhibitor comprises a polypeptide fragment of the MAVS protein (e.g., human MAVS protein). In related embodiments, the polypeptide fragment is a competitive inhibitor or dominant negative of the MAVS protein.
In embodiments, the RLR inhibitor comprises amino acids 10-77, 15-77, 20-77, 25-77, 30-77, 35-77, 40-77, 45-77, 50-77, 10-73, 15-73, 20-73, 25-73, 30-73, 35-73, 40-73, 45-73, and 50-73. In related embodiments, the RLR inhibitor further comprises amino acids from the PRR (any amino acids from 107-173, e.g., 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, or 67 amino acids thereof (or any number therebetween)) and/or the TM (any amino acids from 514-535, e.g., 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, or 22 amino acids thereof). In some embodiments, the RLR inhibitor comprises amino acids 50-73 of the MAVS protein (GNRDTLWHLFNTLQRRPGWVEYFI; SEQ ID NO: 1).
In aspects, the invention provides RLR activators that activate the MAVS adaptor protein.
In any of the above aspects and embodiments, the RLR inhibitor or activator further contains a targeting moiety. In embodiments, the targeting moiety facilitates delivery of the RLR inhibitor or activator to the cytosol of a cell. In related embodiments, the targeting moiety contains a cell penetrating domain of the Drosophila antennapedia protein. The cell penetrating domain can contain amino acids RQIKIWFQNRRMKWKK (SEQ ID NO: 2).
Additional targeting moieties suitable for use in the present invention are well known in the art. Exemplary targeting moieties include, but are not limited to TAT (see Wadia et al., Nat. Med. 10:310-315 (2004); and Kameyama et al., Bioconjugate Chem. 17:597-602 (2006)) and Pep-1 (see Morris et al., Nat. Biotechnol. 19:1173-1176 (2001)).
In any of the above aspects and embodiments, the RLR inhibitor or activator further contains a detectable moiety. Detectable moieties are well known in the art and can be detected by spectroscopic, photochemical, biochemical, immunochemical, physical, or chemical means. Exemplary moieties include, but are not limited to, enzymes, fluorescent molecules, particle labels, electron-dense reagents, radiolabels, biotin, digoxigenin, or a hapten or a protein that has been made detectable.
The RLR inhibitor or activator can be covalently or non-covalently linked to a moiety (e.g., targeting moiety and/or detectable moiety). In embodiments, the RLR inhibitor or activator are covalently linked to the moiety. In related embodiments, the covalent linkage of the moiety is N-terminal to the polypeptide fragment. In related embodiments, the covalent linkage of the moiety is C-terminal to the peptide fragment.
In aspects, the invention provides an RLR inhibitor containing GNRDTLWHLFNTLQRRPGWVEYFI (SEQ ID NO: 1). In embodiments, the RLR inhibitor further comprises RQIKIWFQNRRMKWKK (SEQ ID NO: 2). In related embodiments, the RLR inhibitor is the fusion protein GNRDTLWHLFNTLQRRPGWVEYFI-RQIKIWFQNRRMKWKK (SEQ ID NO: 3).
The invention further embraces variants and equivalents which are substantially homologous to the RLR inhibitors and activators described herein. These can contain, for example, conservative substitution mutations, i.e., the substitution of one or more amino acids by similar amino acids. For example, conservative substitution refers to the substitution of an amino acid with another within the same general class such as, for example, one acidic amino acid with another acidic amino acid, one basic amino acid with another basic amino acid, or one neutral amino acid by another neutral amino acid. What is intended by a conservative amino acid substitution is well known in the art
The invention also provides isolated polypeptides of the inhibitors or activators of the invention, as well as isolated polynucleotides encoding the polypeptides. In addition, the invention further provides expression vectors comprising the isolated polynucleotides, as well as host cells containing the expression vectors.
The term “polynucleotide encoding a polypeptide” encompasses a polynucleotide which includes only coding sequences for the polypeptide as well as a polynucleotide which includes additional coding and/or non-coding sequences. The polynucleotides of the invention can be in the form of RNA or in the form of DNA. DNA includes cDNA, genomic DNA, and synthetic DNA; and can be double-stranded or single-stranded, and if single stranded can be the coding strand or non-coding (anti-sense) strand.
The present invention further relates to variants of the polynucleotides, for example, fragments, analogs, and derivatives. The variant of the polynucleotide can be a naturally occurring allelic variant of the polynucleotide or a non-naturally occurring variant of the polynucleotide. In certain embodiments, the polynucleotide can have a coding sequence which is a naturally occurring allelic variant of the coding sequence of the disclosed polypeptides. As known in the art, an allelic variant is an alternate form of a polynucleotide sequence that have, for example, a substitution, deletion, or addition of one or more nucleotides, which does not substantially alter the function of the encoded polypeptide.
In embodiments, the polynucleotides can comprise the coding sequence for the mature polypeptide fused in the same reading frame to a polynucleotide which aids, for example, in expression and secretion of a polypeptide from a host cell (e.g., a leader sequence which functions as a secretory sequence for controlling transport of a polypeptide from the cell). The polypeptide having a leader sequence is a preprotein and can have the leader sequence cleaved by the host cell to form the mature form of the polypeptide. The polynucleotides can also encode for a proprotein which is the mature protein plus additional 5′ amino acid residues. A mature protein having a prosequence is a proprotein and is an inactive form of the protein. Once the prosequence is cleaved an active mature protein remains.
In embodiments, the polynucleotides can comprise the coding sequence for the mature polypeptide fused in the same reading frame to a marker sequence that allows, for example, for purification of the encoded polypeptide. For example, the marker sequence can be a hexa-histidine tag (SEQ ID NO: 8) supplied by a pQE-9 vector to provide for purification of the mature polypeptide fused to the marker in the case of a bacterial host, or the marker sequence can be a hemagglutinin (HA) tag derived from the influenza hemagglutinin protein when a mammalian host (e.g., COS-7 cells) is used. Additional tags include, but are not limited to, Calmodulin tags, FLAG tags, Myc tags, S tags, SBP tags, Softag 1, Softag 3, V5 tag, Xpress tag, Isopeptag, SpyTag, Biotin Carboxyl Carrier Protein (BCCP) tags, GST tags, fluorescent protein tags (e.g., green fluorescent protein tags), maltose binding protein tags, Nus tags, Strep-tag, thioredoxin tag, TC tag, Ty tag, and the like.
In embodiments, the present invention provides isolated nucleic acid molecules having a nucleotide sequence at least 80% identical, at least 85% identical, at least 90% identical, at least 95% identical, or at least 96%, 97%, 98% or 99% identical to a polynucleotide encoding a polypeptide comprising an RLR activator or inhibitor of the present invention.
By a polynucleotide having a nucleotide sequence at least, for example, 95% “identical” to a reference nucleotide sequence is intended that the nucleotide sequence of the polynucleotide is identical to the reference sequence except that the polynucleotide sequence can include up to five point mutations per each 100 nucleotides of the reference nucleotide sequence. In other words, to obtain a polynucleotide having a nucleotide sequence at least 95% identical to a reference nucleotide sequence, up to 5% of the nucleotides in the reference sequence can be deleted or substituted with another nucleotide, or a number of nucleotides up to 5% of the total nucleotides in the reference sequence can be inserted into the reference sequence. These mutations of the reference sequence can occur at the amino- or carboxy-terminal positions of the reference nucleotide sequence or anywhere between those terminal positions, interspersed either individually among nucleotides in the reference sequence or in one or more contiguous groups within the reference sequence.
As a practical matter, whether any particular nucleic acid molecule is at least 80% identical, at least 85% identical, at least 90% identical, and in some embodiments, at least 95%, 96%, 97%, 98%, or 99% identical to a reference sequence can be determined conventionally using known computer programs such as the Bestfit program (Wisconsin Sequence Analysis Package, Version 8 for Unix, Genetics Computer Group, University Research Park, 575 Science Drive, Madison, Wis. 53711). Bestfit uses the local homology algorithm of Smith and Waterman, Advances in Applied Mathematics 2: 482 489 (1981), to find the best segment of homology between two sequences. When using Bestfit or any other sequence alignment program to determine whether a particular sequence is, for instance, 95% identical to a reference sequence according to the present invention, the parameters are set such that the percentage of identity is calculated over the full length of the reference nucleotide sequence and that gaps in homology of up to 5% of the total number of nucleotides in the reference sequence are allowed.
The polynucleotide variants can contain alterations in the coding regions, non-coding regions, or both. In some embodiments, the polynucleotide variants contain alterations which produce silent substitutions, additions, or deletions, but do not alter the properties or activities of the encoded polypeptide. In some embodiments, nucleotide variants are produced by silent substitutions due to the degeneracy of the genetic code. Polynucleotide variants can be produced for a variety of reasons, e.g., to optimize codon expression for a particular host (change codons in the human mRNA to those preferred by a bacterial host such as E. coli).
The polypeptides of the present invention can be recombinant polypeptides, natural polypeptides, or synthetic polypeptides comprising an RLR activator or inhibitor as described herein. It will be recognized in the art that some amino acid sequences of the invention can be varied without significant effect of the structure or function of the protein. Thus, the invention further includes variations of the polypeptides which show substantial activity or which include regions of the RLR activators or inhibitors of the present invention. Such mutants include deletions, insertions, inversions, repeats, and type substitutions.
The polypeptides and analogs can be further modified to contain additional chemical moieties not normally part of the protein. Those derivatized moieties can improve the solubility, the biological half life or absorption of the protein. The moieties can also reduce or eliminate any desirable side effects of the proteins and the like. An overview for those moieties can be found in Remington's Pharmaceutical Sciences, 20th ed., Mack Publishing Co., Easton, Pa. (2000).
The isolated polypeptides described herein can be produced by any suitable method known in the art. Such methods range from direct protein synthetic methods to constructing a DNA sequence encoding isolated polypeptide sequences and expressing those sequences in a suitable transformed host. In some embodiments, a DNA sequence is constructed using recombinant technology by isolating or synthesizing a DNA sequence encoding a wild-type protein of interest. Optionally, the sequence can be mutagenized by site-specific mutagenesis to provide functional analogs thereof. See, e.g. Zoeller et al., Proc. Nat'l. Acad. Sci. USA 81:5662-5066 (1984) and U.S. Pat. No. 4,588,585.
In embodiments, a DNA sequence encoding a polypeptide of interest would be constructed by chemical synthesis using an oligonucleotide synthesizer. Such oligonucleotides can be designed based on the amino acid sequence of the desired polypeptide and selecting those codons that are favored in the host cell in which the recombinant polypeptide of interest will be produced. Standard methods can be applied to synthesize an isolated polynucleotide sequence encoding an isolated polypeptide of interest. For example, a complete amino acid sequence can be used to construct a back-translated gene. Further, a DNA oligomer containing a nucleotide sequence coding for the particular isolated polypeptide can be synthesized. For example, several small oligonucleotides coding for portions of the desired polypeptide can be synthesized and then ligated. The individual oligonucleotides typically contain 5′ or 3′ overhangs for complementary assembly.
Once assembled (e.g., by synthesis, site-directed mutagenesis, or another method), the polynucleotide sequences encoding a particular isolated polypeptide of interest will be inserted into an expression vector and optionally operatively linked to an expression control sequence appropriate for expression of the protein in a desired host. Proper assembly can be confirmed by nucleotide sequencing, restriction mapping, and expression of a biologically active polypeptide in a suitable host. As well known in the art, in order to obtain high expression levels of a transfected gene in a host, the gene can be operatively linked to transcriptional and translational expression control sequences that are functional in the chosen expression host.
Recombinant expression vectors are used to amplify and express DNA encoding the RLR activators or inhibitors. Recombinant expression vectors are replicable DNA constructs which have synthetic or cDNA-derived DNA fragments encoding an RLR activator or inhibitor or a bioequivalent analog operatively linked to suitable transcriptional or translational regulatory elements derived from mammalian, microbial, viral or insect genes. A transcriptional unit generally comprises an assembly of (1) a genetic element or elements having a regulatory role in gene expression, for example, transcriptional promoters or enhancers, (2) a structural or coding sequence which is transcribed into mRNA and translated into protein, and (3) appropriate transcription and translation initiation and termination sequences, as described in detail below. Such regulatory elements can include an operator sequence to control transcription. The ability to replicate in a host, usually conferred by an origin of replication, and a selection gene to facilitate recognition of transformants can additionally be incorporated. DNA regions are operatively linked when they are functionally related to each other. For example, DNA for a signal peptide (secretory leader) is operatively linked to DNA for a polypeptide if it is expressed as a precursor which participates in the secretion of the polypeptide; a promoter is operatively linked to a coding sequence if it controls the transcription of the sequence; or a ribosome binding site is operatively linked to a coding sequence if it is positioned so as to permit translation. Generally, operatively linked means contiguous, and in the case of secretory leaders, means contiguous and in reading frame. Structural elements intended for use in yeast expression systems include a leader sequence enabling extracellular secretion of translated protein by a host cell. Alternatively, where recombinant protein is expressed without a leader or transport sequence, it can include an N-terminal methionine residue. This residue can optionally be subsequently cleaved from the expressed recombinant protein to provide a final product.
The choice of expression control sequence and expression vector will depend upon the choice of host. A wide variety of expression host/vector combinations can be employed. Useful expression vectors for eukaryotic hosts, include, for example, vectors comprising expression control sequences from SV40, bovine papilloma virus, adenovirus and cytomegalovirus. Useful expression vectors for bacterial hosts include known bacterial plasmids, such as plasmids from Escherichia coli, including pCR 1, pBR322, pMB9 and their derivatives, wider host range plasmids, such as M13 and filamentous single-stranded DNA phages.
Suitable host cells for expression of a polypeptide include prokaryotes, yeast, insect or higher eukaryotic cells under the control of appropriate promoters. Prokaryotes include gram negative or gram positive organisms, for example E. coli or bacilli. Higher eukaryotic cells include established cell lines of mammalian origin. Cell-free translation systems could also be employed. Appropriate cloning and expression vectors for use with bacterial, fungal, yeast, and mammalian cellular hosts are well known in the art (see Pouwels et al., Cloning Vectors: A Laboratory Manual, Elsevier, N.Y., 1985).
Various mammalian or insect cell culture systems are also advantageously employed to express recombinant protein. Expression of recombinant proteins in mammalian cells can be performed because such proteins are generally correctly folded, appropriately modified and completely functional. Examples of suitable mammalian host cell lines include the COS-7 lines of monkey kidney cells, described by Gluzman (Cell 23:175, 1981), and other cell lines capable of expressing an appropriate vector including, for example, L cells, C127, 3T3, Chinese hamster ovary (CHO), HeLa and BHK cell lines. Mammalian expression vectors can comprise nontranscribed elements such as an origin of replication, a suitable promoter and enhancer linked to the gene to be expressed, and other 5′ or 3′ flanking nontranscribed sequences, and 5′ or 3′ nontranslated sequences, such as necessary ribosome binding sites, a polyadenylation site, splice donor and acceptor sites, and transcriptional termination sequences. Baculovirus systems for production of heterologous proteins in insect cells are reviewed by Luckow and Summers, Bio/Technology 6:47 (1988).
The proteins produced by a transformed host can be purified according to any suitable method. Such standard methods include chromatography (e.g., ion exchange, affinity and sizing column chromatography, and the like), centrifugation, differential solubility, or by any other standard technique for protein purification. Affinity tags such as hexahistidine (SEQ ID NO: 8), maltose binding domain, influenza coat sequence, glutathione-S-transferase, and the like can be attached to the protein to allow easy purification by passage over an appropriate affinity column. Isolated proteins can also be physically characterized using such techniques as proteolysis, nuclear magnetic resonance and x-ray crystallography.
For example, supernatants from systems which secrete recombinant protein into culture media can be first concentrated using a commercially available protein concentration filter, for example, an Amicon or Millipore Pellicon ultrafiltration unit. Following the concentration step, the concentrate can be applied to a suitable purification matrix. Alternatively, an anion exchange resin can be employed, for example, a matrix or substrate having pendant diethylaminoethyl (DEAE) groups. The matrices can be acrylamide, agarose, dextran, cellulose or other types commonly employed in protein purification. Alternatively, a cation exchange step can be employed. Suitable cation exchangers include various insoluble matrices comprising sulfopropyl or carboxymethyl groups. Finally, one or more reversed-phase high performance liquid chromatography (RP-HPLC) steps employing hydrophobic RP-HPLC media, e.g., silica gel having pendant methyl or other aliphatic groups, can be employed to further purify a cancer stem cell protein-Fc composition. Some or all of the foregoing purification steps, in various combinations, can also be employed to provide a homogeneous recombinant protein.
Recombinant protein produced in bacterial culture can be isolated, for example, by initial extraction from cell pellets, followed by one or more concentration, salting-out, aqueous ion exchange or size exclusion chromatography steps. High performance liquid chromatography (HPLC) can be employed for final purification steps. Microbial cells employed in expression of a recombinant protein can be disrupted by any convenient method, including freeze-thaw cycling, sonication, mechanical disruption, or use of cell lysing agents.

One of skill in the art can readily formulate a pharmaceutical composition having the desired characteristics (e.g., route of administration, biosafety, and release profile).
Methods for preparing the pharmaceutical compositions include the step of bringing into association the active ingredient with a pharmaceutically acceptable carrier and, optionally, one or more accessory ingredients. The pharmaceutical compositions can be prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers, or finely divided solid carriers, or both, and then, if necessary, shaping the product. Additional methodology for preparing the pharmaceutical compositions, including the preparation of multilayer dosage forms, are described in Ansel's Pharmaceutical Dosage Forms and Drug Delivery Systems (9th ed., Lippincott Williams & Wilkins), which is hereby incorporated by reference.
Methods of Delivery
The pharmaceutical compositions of the invention can be administered to a subject by oral and non-oral means (e.g., topically, transdermally, or by injection). Such modes of administration and the methods for preparing an appropriate pharmaceutical composition for use therein are described in Gibaldi's Drug Delivery Systems in Pharmaceutical Care (1st ed., American Society of Health-System Pharmacists), which is hereby incorporated by reference.
In embodiments, the pharmaceutical compositions are administered orally in a solid form.
Pharmaceutical compositions suitable for oral administration can be in the form of capsules, cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, granules, or as a solution or a suspension in an aqueous or non-aqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert base, such as gelatin and glycerin, or sucrose and acacia) and/or as mouth washes and the like, each containing a predetermined amount of a compound(s) described herein, a derivative thereof, or a pharmaceutically acceptable salt or prodrug thereof as the active ingredient(s). The active ingredient can also be administered as a bolus, electuary, or paste.
In solid dosage forms for oral administration (e.g., capsules, tablets, pills, dragees, powders, granules and the like), the active ingredient is mixed with one or more pharmaceutically acceptable carriers, excipients, or diluents, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, lactose, sucrose, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinyl pyrrolidone, sucrose and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; and (10) coloring agents.

Solid compositions of a similar type can also be prepared using fillers in soft and hard-filled gelatin capsules, and excipients such as lactose or milk sugars, as well as high molecular weight polyethylene glycols and the like.
A tablet can be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets can be prepared using binders (for example, gelatin or hydroxypropylmethyl cellulose), lubricants, inert diluents, preservatives, disintegrants (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-actives, and/or dispersing agents. Molded tablets can be made by molding in a suitable machine a mixture of the powdered active ingredient moistened with an inert liquid diluent.
The tablets and other solid dosage forms, such as dragees, capsules, pills, and granules, can optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the art.
The pharmaceutical compositions can also be formulated so as to provide slow, extended, or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymer matrices, liposomes and/or microspheres. The pharmaceutical compositions can also optionally contain opacifying agents and may be of a composition that releases the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally, in a delayed manner. Examples of embedding compositions include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more pharmaceutically acceptable carriers, excipients, or diluents well known in the art (see, e.g., Remington and Remington's).
The pharmaceutical compositions can be sterilized by, for example, filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use.
In embodiments, the pharmaceutical compositions are administered orally in a liquid form.
Liquid dosage forms for oral administration of an active ingredient include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredient, the liquid dosage forms can contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents and emulsifiers, such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols and fatty acid esters of sorbitan, and mixtures thereof. In addition to inert diluents, the liquid pharmaceutical compositions can include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming and preservative agents, and the like.
Suspensions, in addition to the active ingredient(s) can contain suspending agents such as, but not limited to, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.
In embodiments, the pharmaceutical compositions are administered by non-oral means such as by topical application, transdermal application, injection, and the like. In related embodiments, the pharmaceutical compositions are administered parenterally by injection, infusion, or implantation (e.g., intravenous, intramuscular, intraarticular, subcutaneous, and the like).
Compositions for parenteral use can be presented in unit dosage forms, e.g. in ampoules or in vials containing several doses, and in which a suitable preservative can be added. Such compositions can be in form of a solution, a suspension, an emulsion, an infusion device, a delivery device for implantation, or it can be presented as a dry powder to be reconstituted with water or another suitable vehicle before use. One or more co-vehicles, such as ethanol, can also be employed. Apart from the active ingredient(s), the compositions can contain suitable parenterally acceptable carriers and/or excipients or the active ingredient(s) can be incorporated into microspheres, microcapsules, nanoparticles, liposomes, or the like for controlled release. Furthermore, the compositions can also contain suspending, solubilising, stabilising, pH-adjusting agents, and/or dispersing agents.
The pharmaceutical compositions can be in the form of sterile injections. To prepare such a composition, the active ingredient is dissolved or suspended in a parenterally acceptable liquid vehicle. Exemplary vehicles and solvents include, but are not limited to, water, water adjusted to a suitable pH by addition of an appropriate amount of hydrochloric acid, sodium hydroxide or a suitable buffer, 1,3-butanediol, Ringer's solution and isotonic sodium chloride solution. The pharmaceutical composition can also contain one or more preservatives, for example, methyl, ethyl or n-propyl p-hydroxybenzoate. To improve solubility, a dissolution enhancing or solubilising agent can be added or the solvent can contain 10-60% w/w of propylene glycol or the like.
The pharmaceutical compositions can contain one or more pharmaceutically acceptable sterile isotonic aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders, which can be reconstituted into sterile injectable solutions or dispersions just prior to use. Such pharmaceutical compositions can contain antioxidants; buffers; bacteriostats; solutes, which render the formulation isotonic with the blood of the intended recipient; suspending agents; thickening agents; preservatives; and the like.
Examples of suitable aqueous and nonaqueous carriers, which can be employed in the pharmaceutical compositions of the invention include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol, and the like), and suitable mixtures thereof, vegetable oils, such as olive oil, and injectable organic esters, such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.
In some embodiments, in order to prolong the effect of an active ingredient, it is desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material having poor water solubility. The rate of absorption of the active ingredient then depends upon its rate of dissolution which, in turn, can depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally-administered active ingredient is accomplished by dissolving or suspending the compound in an oil vehicle. In addition, prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents that delay absorption such as aluminum monostearate and gelatin.
Controlled release parenteral compositions can be in form of aqueous suspensions, microspheres, microcapsules, magnetic microspheres, oil solutions, oil suspensions, emulsions, or the active ingredient can be incorporated in biocompatible carrier(s), liposomes, nanoparticles, implants or infusion devices.
Materials for use in the preparation of microspheres and/or microcapsules include biodegradable/bioerodible polymers such as polyglactin, poly-(isobutyl cyanoacrylate), poly(2-hydroxyethyl-L-glutamine) and poly(lactic acid).
Biocompatible carriers which can be used when formulating a controlled release parenteral formulation include carbohydrates such as dextrans, proteins such as albumin, lipoproteins or antibodies.
Materials for use in implants can be non-biodegradable, e.g., polydimethylsiloxane, or biodegradable such as, e.g., poly(caprolactone), poly(lactic acid), poly(glycolic acid) or poly(ortho esters).
In embodiments, the active ingredient(s) are administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation, or solid particles containing the compound. A nonaqueous (e.g., fluorocarbon propellant) suspension can be used. The pharmaceutical composition can also be administered using a sonic nebulizer, which would minimize exposing the agent to shear, which can result in degradation of the compound.
Ordinarily, an aqueous aerosol is made by formulating an aqueous solution or suspension of the active ingredient(s) together with conventional pharmaceutically-acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular compound, but typically include nonionic surfactants (Tweens, Pluronics, or polyethylene glycol), innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars or sugar alcohols. Aerosols generally are prepared from isotonic solutions.
Dosage forms for topical or transdermal administration of an active ingredient(s) includes powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches and inhalants. The active ingredient(s) can be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants as appropriate.
Transdermal patches suitable for use in the present invention are disclosed in Transdermal Drug Delivery: Developmental Issues and Research Initiatives (Marcel Dekker Inc., 1989) and U.S. Pat. Nos. 4,743,249, 4,906,169, 5,198,223, 4,816,540, 5,422,119, 5,023,084, which are hereby incorporated by reference. The transdermal patch can also be any transdermal patch well known in the art, including transscrotal patches. Pharmaceutical compositions in such transdermal patches can contain one or more absorption enhancers or skin permeation enhancers well known in the art (see, e.g., U.S. Pat. Nos. 4,379,454 and 4,973,468, which are hereby incorporated by reference). Transdermal therapeutic systems for use in the present invention can be based on iontophoresis, diffusion, or a combination of these two effects.
Transdermal patches have the added advantage of providing controlled delivery of active ingredient(s) to the body. Such dosage forms can be made by dissolving or dispersing the active ingredient(s) in a proper medium. Absorption enhancers can also be used to increase the flux of the active ingredient across the skin. The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the active ingredient(s) in a polymer matrix or gel.
Such pharmaceutical compositions can be in the form of creams, ointments, lotions, liniments, gels, hydrogels, solutions, suspensions, sticks, sprays, pastes, plasters and other kinds of transdermal drug delivery systems. The compositions can also include pharmaceutically acceptable carriers or excipients such as emulsifying agents, antioxidants, buffering agents, preservatives, humectants, penetration enhancers, chelating agents, gel-forming agents, ointment bases, perfumes, and skin protective agents.
Examples of emulsifying agents include, but are not limited to, naturally occurring gums, e.g. gum acacia or gum tragacanth, naturally occurring phosphatides, e.g. soybean lecithin and sorbitan monooleate derivatives.
Examples of antioxidants include, but are not limited to, butylated hydroxy anisole (BHA), ascorbic acid and derivatives thereof, tocopherol and derivatives thereof, and cysteine.
Examples of preservatives include, but are not limited to, parabens, such as methyl or propyl p-hydroxybenzoate and benzalkonium chloride.
Examples of humectants include, but are not limited to, glycerin, propylene glycol, sorbitol and urea.
Examples of penetration enhancers include, but are not limited to, propylene glycol, DMSO, triethanolamine, N,N-dimethylacetamide, N,N-dimethylformamide, 2-pyrrolidone and derivatives thereof, tetrahydrofurfuryl alcohol, propylene glycol, diethylene glycol monoethyl or monomethyl ether with propylene glycol monolaurate or methyl laurate, eucalyptol, lecithin, Transcutol®, and Azone®.
Examples of chelating agents include, but are not limited to, sodium EDTA, citric acid and phosphoric acid.
Examples of gel forming agents include, but are not limited to, Carbopol, cellulose derivatives, bentonite, alginates, gelatin and polyvinylpyrrolidone.
In addition to the active ingredient(s), the ointments, pastes, creams, and gels of the present invention can contain excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof.
Powders and sprays can contain excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons, and volatile unsubstituted hydrocarbons, such as butane and propane.
Injectable depot forms are made by forming microencapsule matrices of compound(s) of the invention in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of compound to polymer, and the nature of the particular polymer employed, the rate of compound release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissue.
Subcutaneous implants are well known in the art and are suitable for use in the present invention. Subcutaneous implantation methods are preferably non-irritating and mechanically resilient. The implants can be of matrix type, of reservoir type, or hybrids thereof. In matrix type devices, the carrier material can be porous or non-porous, solid or semi-solid, and permeable or impermeable to the active compound or compounds. The carrier material can be biodegradable or may slowly erode after administration. In some instances, the matrix is non-degradable but instead relies on the diffusion of the active compound through the matrix for the carrier material to degrade. Alternative subcutaneous implant methods utilize reservoir devices where the active compound or compounds are surrounded by a rate controlling membrane, e.g., a membrane independent of component concentration (possessing zero-order kinetics). Devices consisting of a matrix surrounded by a rate controlling membrane also suitable for use.
Both reservoir and matrix type devices can contain materials such as polydimethylsiloxane, such as SilasticTM, or other silicone rubbers. Matrix materials can be insoluble polypropylene, polyethylene, polyvinyl chloride, ethylvinyl acetate, polystyrene and polymethacrylate, as well as glycerol esters of the glycerol palmitostearate, glycerol stearate, and glycerol behenate type. Materials can be hydrophobic or hydrophilic polymers and optionally contain solubilising agents.
Subcutaneous implant devices can be slow-release capsules made with any suitable polymer, e.g., as described in U.S. Pat. Nos. 5,035,891 and 4,210,644, which are hereby incorporated by reference.
In general, at least four different approaches are applicable in order to provide rate control over the release and transdermal permeation of a drug compound. These approaches are: membrane-moderated systems, adhesive diffusion-controlled systems, matrix dispersion-type systems and microreservoir systems. It is appreciated that a controlled release percutaneous and/or topical composition can be obtained by using a suitable mixture of these approaches.
In a membrane-moderated system, the active ingredient is present in a reservoir which is totally encapsulated in a shallow compartment molded from a drug-impermeable laminate, such as a metallic plastic laminate, and a rate-controlling polymeric membrane such as a microporous or a non-porous polymeric membrane, e.g., ethylene-vinyl acetate copolymer. The active ingredient is released through the rate controlling polymeric membrane. In the drug reservoir, the active ingredient can either be dispersed in a solid polymer matrix or suspended in an unleachable, viscous liquid medium such as silicone fluid. On the external surface of the polymeric membrane, a thin layer of an adhesive polymer is applied to achieve an intimate contact of the transdermal system with the skin surface. The adhesive polymer is preferably a polymer which is hypoallergenic and compatible with the active drug substance.
In an adhesive diffusion-controlled system, a reservoir of the active ingredient is formed by directly dispersing the active ingredient in an adhesive polymer and then by, e.g., solvent casting, spreading the adhesive containing the active ingredient onto a flat sheet of substantially drug-impermeable metallic plastic backing to form a thin drug reservoir layer.
A matrix dispersion-type system is characterized in that a reservoir of the active ingredient is formed by substantially homogeneously dispersing the active ingredient in a hydrophilic or lipophilic polymer matrix. The drug-containing polymer is then molded into disc with a substantially well-defined surface area and controlled thickness. The adhesive polymer is spread along the circumference to form a strip of adhesive around the disc.
A microreservoir system can be considered as a combination of the reservoir and matrix dispersion type systems. In this case, the reservoir of the active substance is formed by first suspending the drug solids in an aqueous solution of water-soluble polymer and then dispersing the drug suspension in a lipophilic polymer to form a multiplicity of unleachable, microscopic spheres of drug reservoirs.
Any of the above-described controlled release, extended release, and sustained release compositions can be formulated to release the active ingredient in about 30 minutes to about 1 week, in about 30 minutes to about 72 hours, in about 30 minutes to 24 hours, in about 30 minutes to 12 hours, in about 30 minutes to 6 hours, in about 30 minutes to 4 hours, and in about 3 hours to 10 hours. In embodiments, an effective concentration of the active ingredient(s) is sustained in a subject for 4 hours, 6 hours, 8 hours, 10 hours, 12 hours, 16 hours, 24 hours, 48 hours, 72 hours, or more after administration of the pharmaceutical compositions to the subject.

Example 1
Design of a Peptide-Based Inhibitor of RLR Signaling
The study of the innate immune responses to viral infection has been greatly advanced by the use of reverse genetic approaches to dissect virus-induced signaling pathways (Akira et al., Cell 124:783-801 (2006)). In mammalian cells, these approaches have led to the identification of the two primary antiviral response systems known as the Toll-like Receptor (TLR) family and the RIG-I like Receptor (RLR) family. Among these, RLRs are unique in that they function in all mammalian cells, and thus, provide the only known comprehensive immune-surveillance network operating to detect infections (Beutler et al., Annu. Rev. Immunol. 24:353-389 (2006)).
There are currently no known inhibitors that specifically target the RLR-mediated antiviral signaling pathways. In considering how to create a RLR-specific inhibitor, focus was directed to the earliest-acting regulators of signal transduction because it is at the receptor proximal level that the RLR regulators differ from their TLR counterparts (Beutler et al., Annu. Rev. Immunol. 24:353-389 (2006); and Nakhaei et al., Semin. Immunol. 21:215-222 (2009)). The only factors that are unique to the RLR pathways are the receptors themselves, RIG-I and MDA5, and the MAVS adaptor. Since MAVS is essential for both receptors, an inhibitor of MAVS is likely to provide a simple way of blocking all RLR signaling without affecting TLR-mediated signal transduction.
To design an inhibitor that targets MAVS, peptides were designed that corresponded to regions that are important for protein-protein interactions. MAVS alleles that contain a threonine to alanine mutation at position 54 exhibit a dominant negative phenotype (Seth et al., Cell 122:669-682 (2005)). This mutation is present within the CARD-like domain of MAVS, which is responsible for interactions with other CARD-containing proteins such as the RLRs themselves (Meylan et al., Nature 437:1167-1172 (2005)). Thus, a fusion peptide that consists of a 23 mer that overlaps with this region of MAVS and the cell penetrating domain of the Drosophila antennapedia protein was generated (FIG. 1).
As antennapedia-containing peptides rapidly enter the cytosol of any mammalian cell (Joliot, A., Sci. STKE 2005:pe54 (2005)), the generated fusion peptide is an inhibitor that is capable of entering the cytosol of any mammalian cell and has the potential of altering the RLR/MAVS signaling pathways that cause various human diseases.
Example 2
MAVS Peptide Inhibitor Specifically Blocks RLR-Induced Antiviral Signaling in Human Cells
To determine if the MAVS peptide can block RLR signaling in human cells, experiments were performed in the human intestinal epithelial cell (IEC) line T84 comparing the peptide to a previously characterized antennapedia-peptide that targets the TLR adaptor MyD88. These cells were chosen because it is well-known that many viruses penetrate the intestinal epithelium and it has been shown that they respond naturally to both TLR and RLR ligands (FIG. 2 and data not shown). Polarized T84 cells were pretreated for 1 hour with each peptide and then treated for 5 hours with synthetic viral RNA PolyIC, which activates signaling by both RLRs. Quantitative RT-PCR analysis showed that PolyIC activated the expression of the Type I IFN (IFNβ) and Type III IFN IL-29, also known as IFN lambda (FIG. 2). Interestingly, the MAVS peptide completely abolished the expression of both IFNs in response to PolyIC. This inhibitory affect was specific, as the IFN expression was unaffected in cells treated with control peptides. Moreover, neither chloroquine (which blocks TLRs that detect viral RNA) nor inhibitors of the dsRNA dependent kinase PKR, affected polyIC-induced IFN expression. These results indicate that the RLR/MAVS pathway is primarily responsible for PolyIC induced IFN expression. Similar results were obtained when examining PolyIC-induced IFN expression in 293T human kidney cells, indicating that the inhibitory effects of the MAVS peptides are not restricted to T84 cells (not shown).
Finally, to determine if the MAVS inhibitor could prevent RLR-mediated responses to an actual virus, Type III Dearing Strain of mammalian reovirus, which naturally infects human intestinal epithelial cells (Neutra, M. R., J. Infect. Dis. 179 Suppl 3:S441-443 (1999)), were utilized. Reovirus-induced Type I and Type III IFN expression was prevented by MAVS inhibitors, but not MyD88 inhibitors (FIG. 3). Collectively, these data demonstrate the potency of the MAVS peptide inhibitor, and indicates the importance of the RLR/MAVS pathway (as opposed to the TLR/MyD88) pathway in regulating antiviral responses in human cells.
Accordingly, described herein is a cell-permeable peptide inhibitor of antiviral pathways that operates in every human cell. It consists of the cell penetrating domain of the Drosophila antennapedia protein and amino acids 50-73 of the human MAVS protein. This peptide blocks antiviral responses in human cells at micromolar concentrations, and the responses blocked include the expression of Type I and III interferons and various interferon stimulated genes, including viperin. This peptide represents the first described means of blocking antiviral responses in human cells before or at any time after infection by a virus. Moreover, this molecule can serve as a therapeutic to treat inflammatory autoimmune diseases (e.g., those that are caused by inappropriate activation of antiviral responses). No other method currently exists to accomplish these goals.
