TOPICAL COMPOSITIONS AND METHODS FOR UTILIZING PEPTIDES CONTAINING LIPID-MODIFIED CYSTEINE-CONTAINING PEPTIDES

RELATED APPLICATIONS

[0001] This application claims priority to U.S. provisional patent application serial number 61/067,161, filed February 25, 2008, the entire disclosure of which is incorporated herein by reference.

BACKGROUND

[0002] Notwithstanding a desire for healthy skin, consistent exposure to elements exterior to the body causes damage to skin. Such damage may be caused by wounding, photodamage, atrophy, dry skin, etc. Presently, many lotions and creams that are in the market are purported to help alleviate skin damage and/or associated discomfort. Intensive efforts have continued towards the discovery of novel agents to treat and alleviate skin damage.

SUMMARY

[0003] Accordingly, a first aspect of the present invention is directed to an isolated peptide or mixture of peptides having a lipidated cysteine residue, wherein the lipid is a polyisoprenoid, and a composition comprising the peptide or mixture thereof and a carrier suitable for topical administration. The term "topical administration" is meant to include direct or indirect application to a keratinous substrate such as skin, hair or scalp, or to mucosa (e.g., oral administration).

[0004] A second aspect of the present invention is directed to a method of promoting healthy skin or alleviating skin damage due to exposure to the elements, comprising applying to skin, directly or indirectly a composition comprising a peptide or mixture of peptides having a lipidated cysteine residue, wherein the lipid is a polyisoprenoid, and a carrier suitable for topical administration.

[0005] A third aspect of the present invention is directed to a method of making a topical composition for promoting healthy skin or alleviating skin damage due to exposure to the elements, comprising formulating a composition comprising a peptide or mixture of peptides having a lipidated cysteine residue, wherein the lipid is a polyisoprenoid, and a carrier suitable for topical administration.

[0006] In some embodiments of these aspects of the present invention, the sequence of a naturally occurring peptide or mixture of peptides contains a cysteine, whereas in other embodiments, a lipidated cysteine is introduced into the peptide.

[0007] In some embodiments, the peptide is about 2 to 200 amino acids in length while in other embodiments the mixture of peptides have an average size of about 2 to about 200 amino acids.

[0008] In some embodiments, a lipidated cysteine residue is present at the C- terminus. In some embodiments, a lipidated cysteine residue is at least one of the 5 C- terminal amino acid residues. In some embodiments, the peptide contains more than one lipidated cysteine residue, wherein two of the more than one cysteine residues are contiguous or non-contiguous, and wherein the C-terminus of the peptide may or may not be a lipidated cysteine residue. In some embodiments, the peptide contains a non-C-terminal lipidated cysteine residue. In some embodiments, the mixture of peptides may contain cysteine residues at varying amino acid positions in a lipidated peptide.

[0009] In some embodiments, the lipid group present on the cysteine is a geranyl, farnesyl, phytyl, or geranylgeranyl group, such that the lipidated residue is referred to as geranyl cysteine (GC) farnesyl cysteine (FC) phytyl cysteine (PC), and geranylgeranyl cysteine (GGC), respectively. In some embodiments, the peptide contains more than one lipidated cysteine residue wherein the lipid group is the same or different on each cysteine. [0010] In some embodiments, the peptide is present in an amount of about 0.01 to about 10% w/v of the composition.

[0011] In some embodiments, the carrier is aqueous-based and the composition is in the form of an emulsion such as a gel or lotion. In some embodiments, the carrier is nonaqueous based (wherein aside from water that may be present in a commercially available element of the composition, the composition otherwise contains no added water), and the composition is in the form of an ointment or paste. In some embodiments, the composition is suitable for oral use.

[0012] In some embodiments, a pure lipidated peptide is blended with an additional carrier such as hydrolyzed silk protein to result in a uniformly lipid modified peptide. In some embodiments, a uniformly lipid modified peptide is formulated into a hair conditioner. In some embodiments, the hair conditioner contains a base. In some embodiments, the hair conditioner contains water. In some embodiments, the hair conditioner contains cetearyl alcohol.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS

[0013] Topical compositions may contain a peptide or mixture of peptides containing a lipidated cysteine residue, and a carrier. Accordingly, peptides of the present invention

generally have at least one lipidated cysteine residue, and are also referred to herein as lipidated peptides. The inventive compositions may further contain non-lipidated peptides. [0014] Peptides of the present invention may contain as many as 200 amino acid residues, or more, although in some embodiments, the peptide is shorter in length. [0015] Peptides of the present invention may contain a lipidated cysteine residue at the C-terminus of the peptide. In some embodiments, the cysteine residue is located within about 5 residues of the C-terminus of the peptide.

[0016] In some embodiments, the peptide contains more than one cysteine residue.

Of these residues, one, some or all may be lipidated. In such cases when two or more cysteine residues are present in a single peptide, the cysteine residues may be next to each other or one or more amino acid residues may separate each cysteine residue. [0017] The lipid group may be bound to the cysteine residue by way of a chemical bond such as a thioether bond.

[0018] The lipidated peptides of the present invention may contain additional chemical modifications, such as in the N-terminal region. Chemical modification may be performed to the N-terminus or on other free amines in the peptide to enhance solubility, stability, or permeation of the lipidated peptide. Chemical modification techniques useful to enhance solubility, stability, or permeation of lipidated peptides are well known in the art. For example, techniques may include acetylation and/or BOC protection. Modifications may be made at or near the free amino group of the first amino acid in the peptide at the N- terminus in order to alter the chemical properties of the peptide. Other modifications that might be made are well known to those skilled in the art.

[0019] Lipids that may be useful for purposes of this invention are polyisoprenoids, including, for example, a geranyl group, farnesyl group, gernaylgeranyl group and phytyl group. More than one lipid may be used to modify cysteine residues in peptide. For example, if a peptide contains two or more cysteine residues, one cysteine residue may be lipidated with a phytyl group, while another cysteine residue may be lipidated with a farnesyl group.

[0020] In certain embodiments, inventive compositions containing peptides can be used effectively in topical applications to promote healthy epithelia or to treat epithelial- related disorders. These inventive compositions do not exhibit systemic effects when topically applied. Such inventive compositions are useful for, inter alia, their soothing, moisturizing and detergent properties, for treating cosmetic conditions and/or for generally promoting healthy skin. The compositions of the present invention may be usefully

employed in cosmetic, cosmeceutical and general skincare compositions as well as in pharmaceutical compositions.

[0021] Below are certain definitions of terms used herein, many of which are understood by one skilled in the art.

[0022] The phrase "epithelia" or "epithelial" or "epithelial tissues" as used throughout the specification and claims is meant to include skin and mucosal membranes. Thus, the present invention offers compositions useful for treating a condition of the skin or a mucosal membrane, such as, but not limited to, that of a nose, a mouth, an eye, an ear, a vagina and a rectum.

[0023] In certain embodiments, compositions of the present invention include a pharmaceutical composition. As used herein, a "pharmaceutical composition" refers to a composition that is employed to prevent, reduce intensity, cure or otherwise treat a target condition or disease.

[0024] The terms "polypeptide" and "peptide" are used interchangeably herein. In certain embodiments, a "polypeptide" and "peptide" can refer to any sequence having 2 or more amino acids (e.g., 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75,

80, 85, 90, 95, 100, 200, 300, 400, 500, or more). In some embodiments, the number of amino acids is fewer than 1,000, 500, 400, 300, 200, 100, or so. In some embodiments, the term "dipeptide" refers to a "polypeptide" having 2 amino acids.

[0025] In certain embodiments, compositions of the present invention include a cosmetic composition, as defined herein.

1. Description of Exemplary Polypeptides

[0026] Peptides of the present invention may be generated from any known protein, peptide, or mixture of peptides suitable for topical application to keratinous tissue. Proteins known in the art and currently used in topical consumer products include soy protein, keratin, whey, casein, silk, wheat, rice, oat, and other natural sources of protein used in food or cosmetic products.

[0027] In addition, it is contemplated that naturally occurring enzymes within the cell signaling processes may be used to generate peptides of the present invention. For example, a peptide containing a CaaX motif or a lipidated cysteine may be applied topically, and then processed by endogenous enzymes to add a lipid in the case of the CaaX, and to remove the amino acids C-terminal to the cysteine in either case.

[0028] Table I depicts GENBANK® identifier and the C-terminal amino acid sequences of 113 of human proteins that exist in the human body in lipidated form. Included in Table I are sequences derived from G proteins. The four amino acid sequences at the C- terminal constitute the CaaX motif. The three amino acid residues after the cysteine residue of this motif can be removed after the cysteine residue at the C-terminus is lipidated. These modified peptides are thus representative examples of lipidated peptides of the present invention.

[0029] When choosing a peptide (or polypeptide) or combination of peptides (or polypeptides) from Table I for use in the present invention, one skilled in the art may look at the conservation of the upstream amino acid residues. While there is little if any homology or sequence similarity of amino acid sequences upstream of (or N-terminal with respect to) the C-terminal cysteine residue, there is some conservation of the amino acid residue immediately upstream from the C-terminal cysteine residue. Table II shows the conservation of the amino acid residue immediately upstream of the cysteine residue of the CaaX motif. It is believed that a more highly conserved amino acid residue will lead to greater activity of the specific peptide for cell signaling binding sites. For example, serine appears to be the most prevalent amino acid residue upstream from the cysteine residue of the CaaX motif and therefore peptides with a serine residue immediately upstream of a cysteine residue in the C-terminal region may have more activity with respect to cell regulation and signaling proteins. Without being bound by any particular theory or mechanism of action, peptides of the present invention may act to mimic or match sequences such as those in Table I and thus be more active than single amino acid mimics like N-acetyl-S-farnesyl-cysteine (AFC).

Table II

[0030] Known methods in the art may be used to prepare a peptide of desirable length for purposes of the present invention. By way of example, a natural protein may be partially hydro lyzed to achieve a mixture of peptides of about 2-200 amino acid residues, or more. [0031] Not all naturally occurring peptides contain a cysteine residue. Nonetheless, such peptides can be modified to include a lipidated cysteine at any desired position in the peptide sequence, e.g., within 5 residues of the C-terminus, either by introducing the cysteine residue and then adding the lipid group, or by directly introducing a lipidated cysteine residue into to peptide sequence. For example, farnesyl cysteine (FC) may be coupled to a peptide at the N or C-terminus. See Example 1.

[0032] In addition to peptides derived from natural protein sources, e.g., soy protein, keratin, whey, casein, proteins and the like, a synthetic peptide may be used as a starting material to synthesize peptides useful for purposes of the present invention. Like peptides derived from natural protein, synthetic peptides may be modified to include a cysteine residue.

[0033] When a peptide of the present invention contains two or more cysteine residues, and subsequent lipidation of the cysteine residues is desired, it is understood that by using conventional laboratory protocols, all cysteine residues present on the peptide may become lipid modified, i.e., lipidated with a single lipid.

[0034] Lipidated peptides of the present invention may be generated either by chemical modification or enriching for lipid modified peptides.

[0035] Chemical modification may be used to increase the content of lipid-modified cysteine residues within a desired peptide. In one embodiment, a lipid group and peptide containing a cysteine exist separately. The peptide may be chemically modified and thus, lipidated at the cysteine residue. By way of example, a free cysteine residue or peptide containing a cysteine residue may be reacted with an activated lipid such as farnesyl-bromide under suitable conditions such that free cysteine residues become lipidated. See Example 2. [0036] In another embodiment, a cysteine residue may be lipidated and then the lipidated cysteine residue may be used to modify a peptide so that the lipidated cysteine residue is at the C-terminus. A lipid-modified cysteine, such as farnesyl-cysteine, could be coupled to the C-terminus of naturally-derived peptides by protecting the amino groups in the peptide, such as with Fmoc or BOC, and then activating the peptide C-terminus with an activating group and reacting them together. The lipid-modified cysteine could also be coupled to a solid-phase support to enhance the process. See Example 3. [0037] In one such method, attachment of lipid moieties such as a farnesyl to a cysteine residue is performed by reacting the sulfhydryl group of cysteine with farnesyl bromide under basic conditions to attach the farnesyl group. In another method, lipidated peptides are made by using a lipid mercaptan to displace the bromide of a bromoalanine containing peptide. For example, farnesyl mercaptan can be synthesized according to the methods described in U.S. Patent 3,429,970 or Gilbert, et al, J. Am Chem. Soc. 114:3966- 3913 (1992).

[0038] It is also known that lipidated peptides of the present invention may exist naturally. In such instances, it is desirable to enrich for lipidated peptides, in which case they are extracted or isolated from their natural environment. This typically involves taking a natural source of lipidated peptides, i.e., hydrolyzed protein, and using a chromatographic or chemical separation to partially purify the mixture and thus increase the percentage of the peptides in the product that contain a lipid modified cysteine residue. Thus, a higher percentage of lipid modified peptides are present in the product than in the original protein source.

[0039] Alternatively, peptides of the present invention that have been chemically modified and thus lipidated may also be enriched. In this regard, a higher percentage of lipidated peptides or lipid modified cysteine residues will result.

[0040] Methods of enriching for lipidated peptides or lipidated cysteine residues are well known in the art. By way of example, enriching may include use of antibodies or aptamers that specifically recognize lipidated peptides. See Gilbert, et ah, Bioorganic and Medicinal Chemistry. 5(^: 1115-22 (1997).

[0041] In addition, column chromatography, solid-phase, or liquid extraction whose selectivity is based on the hydrophobic nature of the lipid may also be used to enrich for lipid modification. In this case a resin with general or specific affinity for lipids or lipid modified Cysteine residues may be used, i.e., C4 resin, a resin coupled to a hydrophobic dye molecule, serum albumin coupled to a solid support, or a resin with a custom functional group or binding site. Other standard methods of solid phase synthesis are described in Lumbierres, et ah, 11 (24):7405-l5 (2005); Pachamutha, et al, J. Org. Chem. 70(9):3720-3 (2005) and Douat et ah, J. Pept. Sci. 8(1 l):60l-\4 (2002), and Dolence et al, J. Comb. Chem. 2(5):522-36 (2000), all of which are herein incorporated herein by reference. See Example 3.

2. Modulation of the Natural Signaling Process

[0042] Peptides of the present invention may be substrates for isoprenylcysteine carboxyl methyltransferase (ICMT). ICMT is a gene that encodes one of three enzymes that post-translationally modify isoprenylated C-terminal cysteine residues in certain proteins and target those proteins to the cell membrane. This enzyme localizes to the endoplasmic reticulum.

[0043] Similar to AFC, and again without intending to be bound by a particular theory of operation, lipidated peptides of the present invention may compete with cellular targets for modification by ICMT. In addition, lipidated peptides of the present invention may also compete with G-proteins or other peptides modified with farnesyl, geranylgeranyl, or palmitoyl for sites of interaction.

[0044] For example, yeast a-factor is a farnesylated peptide, and is methylated by the same enzyme in the same fashion as the G-proteins. See Hrycyna, et al, EMBO J.

10(7): 1699-709 (1991). Synthetic farnesylated or geranylgeranylated peptides can be methylated by mammalian ICMT. See Stephenson and Clarke J. Biol Chem. 265(27): 16248-

54 (1990), Giner and Rando, Biochemistry 33(50): 15116-23 (1994) which are all herein incorporated herein by reference.

[0045] In addition, a subset of modified peptides may have a higher affinity for their cellular targets and thus may have superior potency to AFC in biochemical, and cellular assays and thus may be useful in the sprit of the present invention. Without being bound by any particular theory, applicants believe this to be the case because the lipidated peptides of the present invention have amino acids in addition to the modified cysteine residue in AFC.

3. Topical Preparations

[0046] The peptides of the present invention may be used with a carrier suitable for topical administration and thus are said to be cosmetically, pharmaceutically or dermatologically acceptable. Carriers are non-toxic to keratinous tissue such as skin and are generally inert, although the carrier can also provide a benefit.

[0047] Topical preparations may be uniformly lipid modified. In other words, all lipidated peptides included within a topical preparation may be modified with a single lipid. On the other hand, not every single peptide in the composition is necessarily lipidated. For example, in a partially hydrolyzed protein extract, not all peptides will contain a cysteine residue. Hence, if treated with farnesyl-bromide, only the fraction containing a cysteine residue will be Updated (see Example 2). Thus, the term "uniformly lipid modified" also refers to all lipidated peptides within a topical preparation that are in a well-defined and consistent distribution. For example, the lipidated peptides contained in a topical preparation may be modified with two or more lipids and be in a well-defined and consistent distribution so as to make the topical preparation uniformly lipid modified.

[0048] The term "topical" refers to administration of inventive compositions at, or immediately beneath, the point of application.

[0049] Topical applications referred to herein are for application onto one or more surfaces(s) including keratinous tissue, i.e., "topically applying." Topical application or "topically applying" may involve direct application to the area of the desired substrate. The topical preparation and/or composition may be applied by pouring, dropping, or spraying, if a liquid; rubbing on, if an ointment, lotion, cream, gel, or the like; dusting, if a powder; spraying, if a liquid or aerosol composition; or by any other appropriate means. [0050] In another embodiment, the topical preparation and/or composition. As used herein, a "cosmetic composition" refers to a composition that is intended to be rubbed, poured, sprinkled, or sprayed on, introduced into, or otherwise applied to a substrate or any part thereof for cleansing, beautifying, promoting attractiveness, or altering the appearance, or an article intended for use as a component of any such article.

[0051] Lipidated peptides are present in topical compositions in concentrations generally ranging from 0.01% to about 10% w/v of the topical composition. In some embodiments, the amount of lipidated peptides may exceed 10% w/v. More typically, however, lipidated peptides are present in topical compositions between 0.1% and 5% w/v. Such amounts are considered "effective" for purposes of the uses of the compositions as described herein.

[0052] Choice of carrier element(s) depends upon the type of formulation envisioned.

The topical preparations may be applied locally to the skin, hair, scalp or mucosa and may be in any form including solutions, oils, creams (e.g., moisturizers), ointments, emulsions (e.g., shampoos), suspensions, gels, lotions, milks, cleansers, sprays, transdermal patches and the like. See Example 4.

[0053] In another embodiment, a polyisoprenyl-protein inhibitor compound, carrier and, optionally, additional active ingredients are formed into a composition. [0054] A solution may be prepared by mixing a solute or dissolved substance (such as a lipidated peptide and, optionally, one or more active ingredient(s)) uniformly throughout a solvent carrier such as water or organic solvents, such as lower alcohols (e.g., lower alkanols such as ethanol and isopropanol) and acetone. A basic emulsion contains at least three components, the two immiscible liquid carriers and the emulsifying agent as well as the lipidated peptide. Most emulsions incorporate an aqueous phase into a non-aqueous phase (or vice versa). However, it is possible to prepare emulsions that are basically non-aqueous, for example, anionic and cationic surfactants of the non-aqueous immiscible system glycerin and olive oil. Gels differ from emulsions in one respect in that they do not contain emulsifiers.

[0055] In yet, another embodiment, the lipidated peptides may be mixed with a gel suspension, (a semi-solid carrier) or solid carrier to form a paste, powder, ointment, cream, lotion, hydrogel or the like.

[0056] For example, ointments may be prepared which are in gel-suspension form.

These are semi-solid preparations intended for external application to the epithelium. Generally, ointment bases are categorized into hydrocarbon bases (oleaginous), which may use white petroleum as a base; adsorption bases (anhydrous), which might use hydrophilic petroleum or anhydrous lanolin; emulsion bases (water and oil type); emulsion bases (oil and water type); and water soluble bases, which often use polyethylene glycol as an ointment base.

[0057] Additional topical preparations using lipidated peptides and carriers can be readily prepared using technology which is known in the art such as described in Remington's Pharmaceutical Sciences, 18th or 19th editions, published by the Mack Publishing Company of Easton, Pa.

[0058] Accordingly, non-limiting representative examples of carriers include moisturizing agents or humectants, pH adjusting agents, a deodorant agent, fragrances, hair conditioning agents, chelating agents, preservatives, emulsifiers or surfactants, thickeners, solubilizing agents, penetration enhancers, anti-irritants and colorants.

[0059] As used herein a "moisturizing agent" is a substance that adds or restores moisture to the skin.

[0060] As is widely recognized in the art, since the pH of the skin is 5.5, topical preparations for skin application, to avoid irritation, should preferably have a pH value of between 4.0 and 7.0, preferably between 5.0 and 6.0, most preferably about 5.5 or substantially 5.5. Accordingly, a pH adjusting composition is typically added to bring the pH of the composition to the desired value. The topical preparation therefore preferably are formulated to have a pH value that ranges between about 4.0 and about 7.0, more preferably between about 5.0 and about 6.0.

[0061] Suitable pH adjusting agents include, for example, but are not limited to, one or more adipic acids, glycines, citric acids, calcium hydroxides, magnesium aluminometasilicates, buffers or any combinations thereof.

Other deodorant agents include, without limitation, odor absorbing materials such as carbonate and bicarbonate salts, e.g., as the alkali metal carbonates and bicarbonates, ammonium and tetraalkylammonium carbonates and bicarbonates, especially the sodium and potassium salts, or any combination of the above. Antiperspirant agents can be incorporated in the compositions of the present invention either in a solubilized or a particulate form and include, for example, aluminum or zirconium astringent salts or complexes.

[0063] As used herein "fragrance" refers to a substance having an aroma. Suitable fragrances include, but are not limited to, eucalyptus oil, camphor synthetic, peppermint oil, clove oil, lavender, chamomile and the like.

[0064] Suitable hair conditioning agents that may be used include, for example, one or more collagens, cationic surfactants, modified silicones, proteins, keratins, dimethicone polyols, quaternary ammonium compounds, halogenated quaternary ammonium compounds, alkoxylated carboxylic acids, alkoxylated alcohols, alkoxylated amides, sorbitan derivatives, esters, polymeric ethers, glyceryl esters, or any combinations thereof.

[0065] Chelating agents may be optionally added to the topical preparation so as to enhance the preservative or preservative system. Preferred chelating agents are mild agents, such as, for example, ethylenediaminetetraacetic acid (EDTA), EDTA derivatives, or any combination thereof.

[0066] Suitable preservatives for use may include, without limitation, one or more alkanols, disodium EDTA (ethylenediamine tetraacetate), EDTA salts, EDTA fatty acid conjugates, isothiazolinone, parabens such as methylparaben and propylparaben, propylene glycols, sorbates, urea derivatives such as diazolindinyl urea, or any combinations thereof. [0067] Emulsifiers (also known as surfactants), as used herein promote the formation and stabilization of an emulsion. Suitable emulsifiers may be natural materials, finely divided solids, or synthetic materials. Natural emulsifying agents may be derived from either animal or vegetable sources. Those from animal sources may include gelatin, egg yolk, casein, wool fat, or cholesterol. Those from vegetable sources may include acacia, tragacanth, chondrus, or pectin. Vegetable sources specifically from cellulose derivatives include methyl cellulose and carboxymethyl cellulose to increase the viscosity. Finely divided emulsifiers may include bentonite, magnesium hydroxide, aluminum hydroxide, or

magnesium trisylicate. Synthetic agents are anionic, cationic, zwitterionic or nonionic. Examples of emulsifiers employed in topical compositions include sodium lauryl sulfate, benzalkonium chloride, polyethylene glycol 400 monostearate, and combinations thereof. [0068] "Thickeners" (also known as gelling agents) as used herein refer to agents that make a topical preparation denser or more viscous in consistency. Thickeners are water- based or oil-based. Suitable thickeners that may be used in the context of the present invention include, for example, non-ionic water-soluble polymers such as hydroxyethylcellulose (commercially available under the Trademark Natrosol™ 250 or 350), cationic water-soluble polymers such as Polyquat 37 (commercially available under the Trademark Synthalen™ CN), fatty alcohols, fatty acids, anionic polymers, and their alkali salts and mixtures thereof.

[0069] As used herein "solubilizing agents" are those substances that enable solutes to dissolve. Representative examples of solubilizing agents that may be used in the context herein include, without limitation, complex-forming solubilizers such as citric acid, ethylenediamine-tetraacetate, sodium meta-phosphate, succinic acid, urea, cyclodextrin, polyvinylpyrrolidone, diethylammonium-ortho-benzoate, and micelle-forming solubilizers such as TWEEN™ and spans, e.g., TWEEN 80™. Other solubilizers that are usable for topical preparations may be, for example, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene n-alkyl ethers, n-alkyl amine n-oxides, polyoxamers, organic solvents, such as acetone, phospholipids and cyclodextrins.

[0070] A "penetration enhancer" is an agent known to accelerate the delivery of a substance through the skin. Suitable penetration enhancers may include, but are not limited to, dimethylsulfoxide (DMSO), dimethyl formamide (DMF), allantoin, urazole, N,N- dimethylacetamide (DMA), decylmethylsulfoxide (Cio MSO), polyethylene glycol monolaurate (PEGML), propylene glycol (PG), propylene glycol monolaurate (PGML), glycerol monolaurate (GML), lecithin, the 1 -substituted azacycloheptan-2-ones, particularly 1-n-dodecylcyclazacyclo- heptan-2-one (available under the trademark Azone™ from Whitby Research Incorporated, Richmond, Va.), alcohols, and the like. The permeation enhancer may also be a vegetable oil. Such oils may include, for example, safflower oil, cottonseed oil and corn oil.

[0071] Additional thickeners, penetration enhancers and other carrier materials or adjuvants may generally be found in Remington's Pharmaceutical Sciences, 18th or 19th editions, published by the Mack Publishing Company of Easton, Pa. which is herein incorporated herein by reference.

[0072] As used herein, an "anti-irritant" is an agent that prevents or reduces soreness, roughness, or inflammation of a bodily part. Suitable anti-irritants that may be used include, for example, but are not limited to, steroidal and non steroidal anti-inflammatory agents or other materials such as aloe vera, chamomile, alpha-bisabolol, cola nitida extract, green tea extract, tea tree oil, licoric extract, allantoin, caffeine or other xanthines, glycyrrhizic acid and its derivatives.

[0073] The presently known anti-irritants can be divided into water-soluble anti- irritants and water-insoluble anti-irritants. Representative examples of such compositions are described, for example, in U.S. Patent 5,482,710 which is herein incorporated herein by reference.

[0074] Colorants may include pigments or dyes or a combination thereof. Preferred pigments may include, but are not limited to, iron oxides, and titanium oxides. Suitable dyes include FD&C approved colorants, D&C approved colorants, and those approved for use in Europe and Japan. See Marmion, D. M., Handbook of US Colorants for Food, Drugs, Cosmetics, and Medical Devices , 3rd ed, 1991 herein incorporated herein by reference. [0075] In certain embodiments, a pharmaceutically acceptable carrier is included in compositions of the present invention. As used herein, "a pharmaceutically acceptable carrier" is any substantially non-toxic carrier conventionally useable for taopical administration of pharmaceuticals in which the peptide will remain stable and bioavailable when applied directly to skin or mucosal surfaces.

[0076] In certain embodiments, compositions of the present invention include a cosmetically acceptable carrier. As used herein, the phrase "cosmetically acceptable carrier" refers to a substantially non-toxic carrier, conventionally useable for the topical administration of cosmetics, with which polypeptides of the present invention will remain stable and bioavailable. It will be understood by one skilled in the art that cosmetically acceptable carriers and pharmaceutically acceptable carriers are similar, if not often identical, in nature.

[0077] Other suitable carriers of the present invention may include pharmaceutically acceptable carriers. For example, water, petroleum jelly (VASELINE®), mineral oil, vegetable oil, animal oil, organic and inorganic waxes, such as microcrystalline, paraffin and ozocerite wax, natural polymers, such as xanthanes, gelatin, cellulose, collagen, starch, or gum arabic, alcohols, polyols, carriers described in the CTFA International Cosmetic Ingredient Dictionary and Handbook, 8th edition, edited by Wenninger and Canterbery, (The Cosmetic, Toiletry, and Fragrance Association, Inc., Washington, D. C, 2000), which is

herein incorporated herein by reference, and the like. Also included are other carriers as described herein.

[0078] The carrier of the composition of the present invention may provide a sustained release or delayed release effect. The carrier can be any material capable of sustained or delayed release of lipidated peptides to provide a more efficient administration resulting in less frequent and/or decreased dosage of lipidated peptides, ease of handling, and extended or delayed effects on epithelial-related conditions. Non-limiting examples of such carriers may include liposomes, microsponges, microspheres, or microcapsules of natural and synthetic polymers and the like. Liposomes which may enhance the localized delivery of lipidated peptides within skin layers may be formed from a variety of phospholipids, such as cholesterol, stearylamines or phosphatidylcholines.

[0079] In some embodiments, the carrier of the composition of the present invention contains a film- forming polymer. Examples of topical carriers with film- forming polymers include sunscreens (U.S. Patent 5,653,965), topical disinfectants (U.S. Patent 7,323,163), and barrier compositions (U.S. Patent 6,210,688). Other examples include carriers containing commercial film- forming polymers such as dehydroxanthan gum, Eastman AQ 38 S, Dermacryl AQF®, Dermacryl 79®, Dermacryl LT®, Dermacryl C®, Aquamere, Avalure™, and the like. Such a film-forming polymer may impart water-resistant characteristics, or delayed-release characteristics.

[0080] In some embodiments, the topical preparation may be incorporated into a carrier which is suitable for administration to the oral mucosa, e.g., a mouthwash, rinse, oral spray, suspension, dental gel, and the like. Typical oral carriers known in the art may be used in the present invention. The pH value of the oral vehicle is generally from about 4 to about 7, and preferably from about 5 to about 6.5. The oral topical preparation may further contain conventional additives normally employed in those products such as a fluorine providing compound and a sweetening agent, providing the additives do not interfere with the therapeutic or cosmetically beneficial properties of the inventive compositions. [0081] Fluorine providing compounds may be fully or slightly water soluble and are characterized by their ability to release fluoride ions or fluoride containing ions in water and by their lack of reaction with other components in the composition. Typical fluorine providing compounds are inorganic fluoride salts such as water-soluble alkali metal, alkaline earth metal, and heavy metal salts, for example, sodium fluoride, potassium fluoride, ammonium fluoride, cuprous fluoride, zinc fluoride, stannic fluoride, stannous fluoride, barium fluoride, sodium fluorosilicate, ammonium fluorosilicate, sodium fluorozirconate,

sodium monofluorophosphate, aluminum mono- and di-fluorophosphates and fluorinated sodium calcium pyrophosphate. Alkali metal fluorides, tin fluoride and monofluorophosphates, such as sodium and stannous fluoride, sodium monofluorophosphate and mixtures thereof, are preferred.

[0082] The amount of fluorine providing compound present may be dependent upon the type of fluorine providing compound employed, the solubility of the fluorine compound, and the nature of the final oral topical preparation. The amount of fluorine providing compound used must be a nontoxic amount. In general, the fluorine providing compound when used will be present in an amount up to about 1%, preferably from about 0.001% to about 0.1%, and most preferably from about 0.001% to about 0.05%, by weight of the oral topical preparation.

[0083] When sweetening agents (sweeteners) are used, those sweeteners well known in the art, including both natural and artificial sweeteners, may be employed. The sweetening agent used may be selected from a wide range of materials including, but not limited to, water-soluble sweetening agents, water-soluble artificial sweetening agents, water-soluble sweetening agents derived from naturally occurring water-soluble sweetening agents, dipeptide based sweetening agents, and protein based sweetening agents, including mixtures thereof.

[0084] The topical composition may further include one or more additional compatible active ingredients which are aimed at providing the topical preparation with another pharmaceutical, cosmeceutical or cosmetic effect, in addition to that provided by a lipidated peptide. "Compatible" as used herein means that the components of such a composition are capable of being combined with each other in a manner such that there is no interaction that would substantially reduce the efficacy of the topical preparation under ordinary conditions of use.

[0085] As used herein, the phrase "additional active ingredient" refers to an agent, other than the lipidated peptide, that exerts a pharmacological, dermatological or any other beneficial activity such as a cosmetic effect. It is to be understood that "other beneficial activity" may be one that is only perceived as such by the subject using the topical preparation described herein.

[0086] Topical preparations containing lipidated peptides, which further include one or more additional active ingredients, can therefore be further efficiently used, in addition to their use as a treatment for an epithelial-related condition, or simply as a cosmetic.

[0087] Additional active ingredients, without limitation, may include one or more, in any combination, of a protective agent, an emollient, an astringent, an irritant, a keratolytic, a sun screening agent, a sun tanning agent, an antibiotic agent, an antifungal agent, an antiviral agent, an antiprotozoal agent, an anti-acne agent, an anesthetic agent, a steroidal antiinflammatory agent, a non-steroidal anti-inflammatory agent, an antipruritic agent, an antioxidant agent, a chemotherapeutic agent, an anti-histamine agent, a vitamin, a hormone, an anti-dandruff agent, an anti-wrinkle agent, an anti-skin atrophy agent, a sclerosing agent, a cleansing agent, a caustic agent and a hypo-pigmenting agent.

[0088] A "protective" is any agent that isolates the exposed surface of the skin or other membrane from harmful or annoying stimuli. Protectives as described herein may take the form of dusting powders, adsorbents, mechanical protective agents, and plasters. Dusting powders are relatively inert and insoluble materials that are used to cover and protect epithelial surfaces, ulcers and wounds. Usually, these substances are finely subdivided powders that absorb moisture and can act as a desiccant. The absorption of skin moisture decreases friction and also discourages certain bacterial growth. Some of the materials used as protective adsorbents include bentonite, insoluble salts of bismuth, boric acid, calcium carbonate, (precipitated), cellulose, corn starch, magnesium stearate, talc, titanium dioxide, zinc oxide, and zinc stearate.

[0089] Protectives also can be administered to the skin to form an adherent, continuous film that may be flexible or semi-rigid depending on the materials and the formulations as well as the manner in which they are applied. This material may serve several purposes including providing occlusion from the external environment, providing chemical support, and serving as vehicles for other medicaments. Mechanical protectives are generally either collodions or plasters. Examples may include aluminum hydroxide gel, collodium, dimethicone, petrolatum gauze, absorbable gelatin film, absorbable gelatin sponge, zinc gelatin, kaolin, lanolin, anhydrous lanolin, mineral oil, mineral oil emulsion, mineral oil light, olive oil, peanut oil, petrolatum, silicones, hydrocolloids and the like. [0090] An example of a protective that may be included is demulcents. Demulcents are protective agents employed primarily to alleviate irritation, particularly mucous membranes or abraded tissues. They often are applied to the surface in a viscid, sticky preparation that covers the area readily and may be medicated. A number of chemical substances possess demulcent properties. These substances may include the alginates, mucilages, gums, dextrins, starches, certain sugars, and polymeric polyhydric glycols. Others include acacia, agar, benzoin, carbomer, gelatin, glycerin, hydroxyethyl cellulose,

hydroxypropyl cellulose, hydroxypropyl methylcellulose, propylene glycol, sodium alginate, tragacanth, hydrogels and the like.

[0091] "Emollients" are generally bland, fatty or oleaginous materials which can be applied locally, particularly to the skin. Emollients increase the tissue moisture content, thereby rendering the skin softer and more pliable. Increased moisture content in the skin can be achieved by preventing water loss with an occlusive water-immiscible barrier, by increasing the water-holding capacity in the skin with humectants, or by altering the desquamation of the outermost skin layer, the stratum corneum. Useful emollients include lanolin, spermaceti, mineral oil, paraffin, petrolatum, white ointment, white petroleum, yellow ointment. Also included are vegetable oils, waxes, cetyl alcohol, glycerin, hydrophilic petrolatum, isopropyl myristate, myristyl alcohol, and oleyl alcohol. [0092] "Astringents" are locally applied, generally protein precipitants, that have such a low cell penetrability that the action essentially is limited to the cell surface and interstitial spaces. The astringent action is accompanied by contraction and wrinkling of the tissue and by blanching. Astringents are used therapeutically to arrest hemorrhage by coagulating the blood, to promote healing, to toughen the skin or to decrease sweating. The principal components of astringents are salts of aluminum, zinc, manganese, iron or bismuth. [0093] An "irritant" is a material that may act locally on the skin to induce, based on irritant concentration, hyperemia, inflammation, and desiccation. Irritant agents include, but are not limited to, alcohol, aromatic ammonia spirits, benzoin tincture, camphor capsicum, and coal tar extracts. Preferably, the irritant is a rubefacient. As used herein "rubefacients" are agents that may induce hyperemia, wherein hyperemia means an increased amount of blood in a body part or organ. Rubefaction, which is induced by rubefacients, results from increased circulation to an injured area and is accompanied by a feeling of comfort, warmth, itching and hyperesthesia.

[0094] Representative examples of sun screening agents usable in context of the present invention may include, without limitation, p-aminobenzoic acid and its salts and derivatives thereof (ethyl, isobutyl, glyceryl esters; p-dimethylaminobenzoic acid); anthranilates (i.e., o-amino-benzoates; methyl, menthyl, phenyl, benzyl, phenylethyl, linalyl, terpinyl, and cyclohexenyl esters); salicylates (amyl, phenyl, octyl, benzyl, menthyl, glyceryl, and di-propylene glycol esters); cinnamic acid derivatives (menthyl and benzyl esters, alpha- phenyl cinnamonitrile; butyl cinnamoyl pyruvate); dihydroxycinnamic acid derivatives (umbelliferone, methylumbelliferone, methylaceto-umbelliferone); trihydroxy-cinnamic acid derivatives (esculetin, methylesculetin, daphnetin, and the glucosides, esculin and daphnin);

[0095] Representative examples of sunless tanning agents usable in the present invention may include, without limitation, dihydroxyacetone, glyceraldehyde, indoles and their derivatives. The sunless tanning agents can be used in combination with the sunscreen agents.

A variety of exemplary formulation techniques that are usable in the process of the present invention is described, for example, in Harry's Cosmeticology , Seventh Edition, Edited by J B Wilkinson and RJ Moore, Longmann Scientific & Technical, 1982. [00117] In another embodiment, the inventive composition entails adding the lipidated peptides to peptides an existing e.g., commercial, topical composition. The existing topical composition may be a pharmaceutical composition, in which case the lipidated peptide or peptides may be considered to be a "new excipient" by the U.S. F.D.A. Characteristics of new excipients can be found in the Guidance for Industry Nonclinical Studies for the Safety Evaluation of Pharmaceutical Excipients issued by the US Food and Drug Administration Center for Drug Evaluation and Research, in May, 2005, herein incorporated by reference. [00118] According to another aspect of the present invention, there is provided a method of treating a medical, cosmetic and/or cosmeceutical condition associated with epithelial tissues. The method is effected by topically applying, an effective amount of the composition of the present invention as described above onto a surface. [00119] As used herein the term "effective amount" refers to the amount of any of the topical preparations of the invention that result in a therapeutic or beneficial effect following its administration to a subject, an animal or human in need thereof. The effect may be curing, minimizing, preventing or ameliorating a disease or disorder, improving the physical appearance and aesthetics (e.g., skin hydration), or may have any other beneficial effect. The concentration of the substance is selected so as to exert its pharmaceutical, cosmeceutical or cosmetic effect, but low enough to avoid significant side effects within the scope and sound judgment of the skilled artisan. The effective amount of the composition may vary with the particular epithelial tissue being treated, the age and physical condition of the biological subject being treated, the severity of the condition, the duration of the treatment, the nature of concurrent therapy, the specific compound, composition or other active ingredient employed, the particular carrier utilized, and like factors.

EXAMPLES

[00139] As depicted in the Examples below, in certain exemplary embodiments, peptides and formulations of the same are prepared according to the following general procedures. It will be appreciated that, although the general methods depict the synthesis of certain peptides and formulations of the present invention, the following general methods, and other methods known to one of ordinary skill in the art, can be applied to each of the peptides and formulations disclosed herein.

EXAMPLE 1

Method of making lipidated peptides

[00140] Protein extract (100 mL, 5 mg/ml) is mixed with trypsin (100 mL, 0.1 mg/ml) or other endopeptidases (0.1 mg/ml) and incubated at 37 ⁰ C for 2 hours. The extract is further digested by exopeptidases (100 mL, 0.1 mg/ml). After digestion, the free amino group of hydrolyzed protein (-4.6 mmole) in buffer solution is stirred with acetic anhydride (10 mL) at room temperature overnight. The protected peptide is converted to an activated ester with 2- (lH-7-Azabenzotriazol-l-yl)-l,l,3,3-tetramethyl uranium hexafluorophosphate (HATU) (1.79 g, 4.6 mmole). The active peptides are coupled to lipidated cysteine residue such as farnesyl-S-cysteine, phytyl-S-cysteine, or geranylgeranyl-S-cysteine (4.6 mmole) with N,N- diisopropylethylamine (1.2 g, 9.2 mmole) at room temperature overnight to yield 1.0 g to 1.8 g of the desired mixture of uniformly lipid modified peptides.

EXAMPLE 2

Method of making lipidated peptides

[00141] Protein extract (100 mL, 5mg/ml) is mixed with trypsin (100 mL, 0.1 mg/ml) or other endopeptidases (0.1 mg/ml) and incubated at 37 ⁰ C for 2 hours. The resulting hydrolyzed mixture of peptides is treated with DTT (770 mg, 4.6 mmole) overnight at room

temperature for reducing disulfide bonds. The free thiol content of a sample of the material is measured using a method such as reaction with Ellman's reagent (DTNB, 5,5'-dithiobis-(2- nitrobenzoic acid)). A sample of hydro lyzed protein extract (1 ml) is dissolved in 0.1 M potassium phosphate buffer at pH 7.4, and is mixed with 20 mM DTNB solution (50 μL) in the same buffer. Absorbance is observed at 412 nm at 3O ⁰ C. The DTNB reagent reacts with free thiol to release 2-nitro-5-thiobenzoic acid (TNB) (1 eq.), which has a molar extinction coefficient of 14,150 M ¹ Cm ^"1 at 3O ⁰ C (the concentration of TNB is equal to the concentration of thiol groups in the protein sample). The peptide digest (50 g) is suspended in ethanol (200 mL) and potassium carbonate (2M aqueous) is added to adjust pH to 9.0. Phytyl-bromide (1.5 mol), farnesyl bromide, or other activated lipid is added slowly at a rate of 500 μL per minute for each mol of free thiol, with vigorous stirring to ensure uniform dispersion of the lipid in the reaction mixture. Stirring is continued for three hours after addition is complete, pH is adjusted to 6.0 with ice cold hydrochloric acid (3N), the reaction mixture is evaporated to dryness, resuspended in water (200 mL) and washed with three portions of hexane (200 mL). The salts are removed by filtering the product through a Sephadex G- 10 column (equilibrated in water), and the desired product is evaporated to dryness. The resultant product is 50.0 g to 52.5 g of uniformly lipid modified peptides.

EXAMPLE 3

Method of making lipidated peptides

The mixture is titrated to pH 7 with aqueous cesium carbonate (3 mL, 2M) and the solvent is evaporated to form crude BOC-FC cesium salt, which is then dissolved in dry tetrahydrofuran (THF, 20 mL each), and is evaporated three times to yield purified BOC-FC cesium salt (10.4551 g). Separately, the Merrifield resin (8.54 g, 1 eq. resin : 1.2 eq. Boc-FC) is pre-swelled in dichloromethane (DCM, 100 mL) for one hour, the DCM is rinsed with N,N-dimethylformamide (DMF, 2x100 mL) to yield an equilibrated Merrifield resin.

[00143] Purified BOC-FC cesium salt is dissolved in DMF (15 mL) is added to the equilibrated Merrifield resin in a 125 mL Erlenmeyer flask. The reaction mixture is placed in a vigorously shaking incubator at 55°C overnight to form BOC-FC-Merrified resin. The BOC-FC-Merrifield resin is recovered by suction filtration, is washed with DMF (3 x 100 mL), 1: 1 DMF: water (3x 100 mL), DCM (3x 100 mL), and methanol (3 x 100 mL), and is

dried in a vacuum desiccator containing potassium hydroxide for 36 hours at 20-25 ⁰ C ambient room temperature to yield BOC-FC-Merrifield resin (11.0608 g). [00144] BOC-FC-Merrifield resin (5.6020 g) is placed in a 250 mL round-bottom flask, and 1: 1 trifluoroacetic acid:DCM (100 mL) is added.

1.0 mmol) is dissolved in DMF (2.5 mL) with HATU (418.3 mg, 1.1 mmol) and triethylamine (415.9 μL, 3 mmol) in a 250 mL Erlenmeyer flask and is swirled for 5 minutes to pre-activate the amino acid. To this mixture is added deprotected FC-resin (1 g, 0.5 mmol). The flask is covered with aluminum foil and is placed in a shaking incubator overnight at 55 ⁰ C to form Boc-Phe-FC-resin.

[00146] Boc-Phe-FC-resin is isolated from the reaction mixture by suction filtration and is washed sequentially with DMF (3x 100 mL), DCM (4x100 mL), and THF (2x 100 mL), then resuspended in a lithium hydroxide solution (100 mL, 0.77M; 3229.4 mg LiOH, 40 mL deionized water, 40 mL THF, 20 mL methanol). The reaction mixture is placed in a shaking incubator at 55 ⁰ C for 3 hours to cleave the desired Boc-Phe-FC from the resin. The resin, which no longer holds the product, is removed by suction filtration, and washed with water (3x 100 mL) and ethyl acetate (3x 100 mL). The combined washes are acidified to pH 5 with saturated aqueous ammonium chloride (25 mL), and extracted in ethyl acetate (3x100 mL). The combined organic phase is dried over sodium sulfate and is evaporated to dryness to yield the desired Boc-Phenylalanyl-FC (254.3 mg).
