[0002] This application contains an ST.26 compliant Sequence Listing, which is submitted concurrently in xml format and is hereby incorporated by reference in its entirety. The .xml copy, created on August 14, 2025, is titled “183B-412971 -WO_SL.xml” and is 2,872,748 bytes in size.BACKGROUND

[0003] Melanocortins are a group of small peptides that bind to a family of five known melanocortin receptors (MC1 R through MC5R). They are derived from a common precursor protein, pro-opiomelanocortin (POMC), which is expressed in the neurons of the central and peripheral nervous system, and in the pituitary gland. The proteolytic cleavage of POMC results in a-, p- and y-melanocortin and adrenocorticotrophic hormone (ACTH), in addition to several other biologically important peptides.

[0004] Melanocortin analogs have been synthesized for the potential regulation and treatment of many conditions, including weight regulation (e.g., obesity, anorexia, and cachexia), hormonal secretion, and hyposecretion of many exocrine glands. However, in regulating these physiological effects, melanocortin analogs have also been shown to cause certain side effects, such as, for example hypertension and cardiac arrhythmias.Docket No.: 183B-412971 -WO

[0005] Despite recent attempts to reduce melanocortin peptide side effects or enhance melanocortin in vivo activity, there still exists a need for highly stable and selective melanocortin analogs in the treatment and prevention of various melanocortin-related diseases.SUMMARY

[0008] The present technology provides non-naturally occurring melanocortin analogs and pharmaceutically acceptable salts, solvates, and stereoisomers thereof, referred to herein collectively as melanocortin analogs. The melanocortin analogs of the present technology may selectively bind the melanocortin 3 receptor and / or the melanocortin 4 receptor over the melanocortin 1 , melanocortin 2, and melanocortin 5 receptors. Some of the melanocortin analogs bind the melanocortin 3 receptor with greater affinity than the melanocortin 4 receptor, whereas other melanocortin analogs bind the melanocortin 4 receptor with greater affinity than the melanocortin 3 receptor. Certain melanocortin analogs bind the melanocortin 3 receptor with the same or generally similar affinity as the melanocortin 4 receptor.

[0009] Each of the melanocortin analogs may have one or more beta hairpin (p-hairpin) and / or beta turn (p-turn) structures. In general, cyclization such as, for example, via a disulfide or lactam bond, may stabilize beta-turns, structurally rigid amino acids, such as, for example, proline, and / or the presence of D-amino acids may induce and / or stabilize betaturns.

[0010] The non-naturally occurring melanocortin analogs of the present technology include one or more of the following features: an N-terminus that stabilizes the melanocortin analog; a pharmacophoric region that binds to one or more melanocortin receptor; and a C- terminus that provides enhanced transport and / or resistance to degradation. The melanocortin analogs may be linear or cyclized.Docket No.: 183B-412971 -WO

[0011] The following description is merely exemplary in nature and is not intended to limit the present technology, its applications, or its uses. The description of specific examples indicated in various embodiments of the present technology are intended for purposes of illustration only and are not intended to limit the scope of the present technology disclosed herein. Moreover, recitation of multiple embodiments having stated features is not intended to exclude other embodiments having additional features or other embodiments incorporating different combinations of the stated features.

[0012] While the embodiments are described in sufficient detail to enable those skilled in the art to practice the present technology, it should be understood that other embodiments may be realized, and that logical changes may be made without departing from the spirit and scope of the present technology. Thus, the detailed description herein is presented for purposes of illustration only and not of limitation. For example, steps recited in any method or process may be executed in any order and are not limited to the order presented. Moreover, any of the steps thereof may be outsourced to or performed by one or more third parties.Definitions

[0013] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present technology belongs. For the purposes of the present technology, the following terms are defined below.

[0014] The articles “a” and “an” are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article. By way of example, “an element” means one element or more than one element.

[0015] The term “about” means a quantity, level, value, number, frequency, percentage, dimension, size, amount, weight, or length that varies by acceptable levels in the art. Typically, such variation may be as much 10% above and below a reference quantity, level, value, number, frequency, percentage, dimension, size, amount, weight or length and such variation may be influenced by standard applicable measurement practices. When theDocket No.: 183B-412971 -WO term “about” is used in conjunction with a numerical range, it modifies that range by extending the boundaries above and below the numerical values set forth.

[0016] As used herein, a “composition” or a “pharmaceutical composition” refers to a mixture of the active ingredient with other chemical components, such as pharmaceutically acceptable carriers and / or excipients.

[0017] As used herein, a “pharmaceutically acceptable carrier” of the first or the second pharmaceutical composition refers to a carrier or diluent that does not cause significant irritation to an organism, does not abrogate the biological activity and properties of the administered active ingredient, and / or does not interact in a deleterious manner with the other components of the composition in which it is contained. The term “carrier” encompasses any excipient, binder, diluent, filler, salt, buffer, solubilizer, lipid, stabilizer, or other material well known in the art for use in pharmaceutical formulations. The choice of a carrier for use in a composition will depend upon the intended route of administration for the composition. The preparation of pharmaceutically acceptable carriers and formulations containing these materials is described in, e.g., Remington's Pharmaceutical Sciences, 21 st Edition, ed. University of the Sciences in Philadelphia, Lippincott, Williams & Wilkins, Philadelphia Pa., 2005, which is incorporated herein by reference in its entirety). Some examples of physiologically acceptable carriers include antioxidants including ascorbic acid; low molecular weight (less than about 10 residues) polypeptides; proteins, such as serum albumin, gelatin, or immunoglobulins; hydrophilic polymers such as polyvinylpyrrolidone; amino acids such as glycine, glutamine, asparagine, arginine or lysine; monosaccharides, disaccharides, and other carbohydrates including glucose, mannose, or dextrins; chelating agents such as EDTA; sugar alcohols such as mannitol or sorbitol; salt-forming counterions such as sodium; and / or nonionic surfactants such as TWEEN® (ICI, Inc.; Bridgewater, N.J.), polyethylene glycol (PEG), and PLURONICS™ (BASF; Florham Park, N.J.). An “excipient” of the first or the second pharmaceutical composition refers to an inert substance added to a composition to further facilitate administration of a compound. Examples, without limitation, of excipients include calcium carbonate, calcium phosphate, various sugars and types of starch, cellulose derivatives, gelatin, vegetable oils, and polyethylene glycols.Docket No.: 183B-412971 -WO

[0018] “Melanocortin analogs,” “melanocortin peptides,” or “melanocortins,” are used interchangeably and refer to melanocortin-receptor ligands, which are macromolecules containing at least one melanocortin pharmacophore. Melanocortin analogs are typically peptides that bind melanocortin receptors under physiological conditions. Melanocortin analogs include non-naturally occurring melanocortin peptides and truncated and / or modified versions of melanocortin full-length protein or peptides. For example, the full-length pro-opiomelanocortin protein (POMC), prior to proteolytic cleavage of “sub-peptides,” consists of 241 amino acids. Tissue-specific proteolytic cleavage of POMC yields peptides ranging in size from 13 amino acids to 76 amino acids. See Bicknell and Lawry, Encyclopedia of Stress, vol. 3, 257-265, Academic Press (2000). Synthesized, non- naturally occurring melanocortin analogs having increased melanocortin receptor activity as discussed herein are approximately 7-12 amino acids in size. Melanocortin analogs exhibit binding functionality with melanocortin receptors. In addition to peptides, the melanocortin analogs include small molecule analogs of melanocortin or portions thereof comprised of organic compounds, inorganic compounds, or combinations of peptide and small molecule — i.e., peptide mimetics, or various combinations thereof. “Melanocortin peptides” can be structurally similar and / or functionally similar to biological melanocortin proteins in their ability to bind melanocortin receptors. Further, the melanocortin analogs generally contain the pharmacophore: His-Phe-Arg-Trp (SEQ ID NO: 1 ) or a modified version thereof, or a structural or functional peptide mimetic thereof.

[0019] A “pharmacophore” is the minimum set of amino acid residues necessary to achieve a physiological effect; or a small molecule that is (with respect to a receptor) a structural mimic of the amino acid residues required for binding to and activation of a receptor. His-Phe-Arg-Trp (SEQ ID NO: 1 ) and their analogs are the pharmacophore of melanocortin for the regulated physiological effect. Therefore, non-naturally occurring melanocortin pharmacophore analogs can be small peptides or organic molecules designed to mimic the appearance or function (including activation or deactivation of receptor activity) of the melanocortin pharmacophore core sequence peptide.

[0020] The terms “bind,” “binding,” “complex,” and “complexing,” refer to all types of physical and chemical binding, reactions, complexing, attraction, chelating and the like.Docket No.: 183B-412971 -WO

[0021] The “peptides” described herein can be (a) naturally occurring, (b) produced by chemical synthesis, (c) produced by recombinant DNA technology, (d) produced by biochemical or enzymatic fragmentation of larger molecules, (e) produced by methods resulting from a combination of methods (a) through (d) listed above, or (f) produced by any other means for producing peptides.

[0022] The term “peptide” as used herein includes any structure comprised of two or more amino acids, including chemical modifications and derivatives of amino acids. The amino acids forming all or a part of a peptide may be naturally occurring amino acids, stereoisomers and modifications of such amino acids, non-protein amino acids, post- translationally modified amino acids, enzymatically modified amino acids, constructs or structures designed to mimic amino acids, and the like, so that the term “peptide” includes pseudopeptides and peptidomimetics, including structures which have a non-peptidic backbone. The term “peptide” also includes dimers or multimers of peptides. A “manufactured” peptide includes a peptide produced by chemical synthesis, recombinant DNA technology, biochemical, or enzymatic fragmentation of larger molecules, combinations of the foregoing or, in general, made by any other method. The term “peptide” includes peptides containing a variable number of amino acid residues, optionally with nonamino acid residue groups at the N- and C-termini, such groups including acyl, acetyl, alkenyl, alkyl, N-alkyl, amine, or amide groups, among others.

[0023] By employing chemical synthesis, a useful means of production, it is possible to introduce various amino acids which do not naturally occur along the chain, modify the N- or C-terminus, and the like, thereby providing for improved stability and formulation, resistance to protease degradation, and the like.

[0024] “Amino acids” are molecules containing an amine group, a carboxylic acid group, and a side-chain that is specific to each amino acid. The key elements of an amino acid are carbon, hydrogen, oxygen, and nitrogen and have the generic formula H2N — CHR — COOH, wherein R represents a side chain group. The various a-amino acids differ in the side-chain moiety that is attached to the a-carbon. The “amino acids” of the present technology include the known naturally occurring protein amino acids, which are referred to by both their common three letter abbreviation and single letter abbreviation. SeeDocket No.: 183B-412971 -WO generally Synthetic Peptides: A User’s Guide, G. A. Grant, editor, W.H. Freeman & Co., New York (1992), the teachings of which are incorporated herein by reference, including the text and table set forth at pages 11 through 24. As set forth above, the term “amino acid” also includes stereoisomers and modifications of naturally occurring protein amino acids, nonprotein amino acids, post-translationally modified amino acids, enzymatically synthesized amino acids, derivatized amino acids, constructs or structures designed to mimic amino acids, and the like. Modified and unusual amino acids are described generally in Synthetic Peptides: A User’s Guide, supra; Hruby et al., Biochem. J. 268:249-262 (1990); and Toniolo, Int. J. Peptide Protein Res. 35:287-300 (1990); the teachings of all of which are incorporated herein by reference.

[0025] The phrase “amino acid side chain moiety” used herein, including as used in the specification and claims, includes any side chain of any amino acid, as the term “amino acid” is defined herein. This thus includes the side chain moiety present in naturally occurring amino acids. It further includes side chain moieties in modified naturally occurring amino acids, such as glycosylated amino acids. It further includes side chain moieties in stereoisomers and modifications of naturally occurring protein amino acids, non-protein amino acids, post-translationally modified amino acids, enzymatically synthesized amino acids, derivatized amino acids, constructs, or structures designed to mimic amino acids, and the like. For example, the side chain moiety of any amino acid disclosed herein is included within the definition. A “derivative” of an amino acid side chain moiety is included within the definition of an amino acid side chain moiety.

[0026] The “derivative” of an amino acid side chain moiety includes any modification to or variation in any amino acid side chain moieties, including a modification of naturally occurring amino acid side chain moieties. By way of example, derivatives of amino acid side chain moieties include straight chain or branched, cyclic or noncyclic, substituted or unsubstituted, saturated or unsaturated, alkyl, aryl or aralkyl moieties.

[0027] In the peptides described herein, conventional amino acid residues have their conventional meaning as given in Chapter 2400, of the Manual of Patent Examining Procedure, 8th Ed. Thus, “Ala” is alanine; “Arg” is arginine; “Asn” is asparagine; “Asp” is aspartic acid; “Cys” is cysteine; “Gin” is glutamine; “Glu” is glutamic acid; “His” is histidine;Docket No.: 183B-412971 -WO“lie” is isoleucine; “Leu” is leucine; “Lys” is lysine; “Met” is methionine; “Phe” is phenylalanine; “Pro” is proline; “Ser” is serine; Thr is threonine; “Trp” is tryptophan; “Tyr” is tryosine; and “Vai” is valine. Unless otherwise indicated, all amino acids abbreviations represent either isomer, i.e., the L-isomer, the D-isomer, or combinations thereof can be used. Thus, for example, “L-Phe” or “IPhe” is L-phenylalanine; “D-Phe” or “dPhe” is D- phenylalanine; dVal is D-valine; dPro is D-proline; “D- / L-Phe” or “d / IPhe” is D-phenylalanine, L-phenylalanine, or combinations thereof; “Phe” is also D-phenylalanine, L-phenylalanine, or combinations thereof, and so on.

[0028] An alpha (oc)-amino acid has the generic formula H2N — CaHR — COOH, where R is a side chain moiety and the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (i.e., the oc-carbon). Other types of amino acids exist when the amino group is attached to a different carbon atom.

[0029] When p-amino acids are incorporated into peptides, two main types of p- peptides exist: those with the side chain residue, R, on the carbon next to the amine are called p3peptides and those with the side chain residue on the carbon next to the carbonyl group are called p2amino acids. Further, p-amino acids may adopt L- or D- stereochemistry. Unless otherwise indicated, all p-amino acid abbreviations represent either isomer, i.e., the L-isomer, the D-isomer, or combinations thereof.

[0030] Gamma (y)-amino acids are amino acids with the carbon atom to which the amino group attaches is separated from the carboxylate moiety by two carbon atoms.

[0031] For additional modified and unusual amino acids, see §2422 of the MPEP, particularly Table 4 at 2400-24. Additionally, “Ac” indicates N-acetyl and “cyclo” and “c” refers to a cyclic structure. “NH2” indicates an amine group, typically added on the C- terminus of a polypeptide. Accordingly, as used herein, an — NH2 moiety on the C-terminus of a peptide indicates an amidated C-terminus.

[0032] Additional abbreviations are used as follows: Orn is ornithine; dOrn is D- ornithine; Dab is 2,4-diaminobutyric acid; dDab is 2,4-D-diaminobutyric acid; Dap is 2,3- diaminopropionic acid; dDap is 2,3-D-diaminopropionic acid; Aad is aminoadipic acid; PhgDocket No.: 183B-412971 -WO is phenylglycine; dPhg is D-phenylglycine; Pen is Penicillamine; dPen is D-Penicillamine; and 2’-D-naphthylalanine (dNal(2’)).

[0033] The term “acyl” includes a group RCO — , where R is an organic group. An example is the acetyl group CH3CO — , referred to herein as “Ac.”

[0034] A peptide or aliphatic moiety is “acylated” when an alkyl or substituted alkyl group as defined above is bonded through one or more carbonyl { — (C=O) — } groups. A peptide is most usually acylated at the N-terminus.

[0035] An “amine” includes compounds that contain an amine group ( — NH2).

[0036] An “amide” includes compounds that have a trivalent nitrogen attached to a carbonyl group (i.e., — CO — NH2), such as for example methylamide, ethylamide, propylamide, and the like. A peptide is most usually amidated at the C-terminus by the addition of an amine ( — NH2) moiety to the C-terminal carboxyl group.

[0037] Amino acids, including stereoisomers and modifications of naturally occurring amino acids, protein amino acids, non-protein amino acids, post-translationally modified amino acids, enzymatically synthesized amino acids, derivatized amino acids, constructs, or structures designed to mimic amino acids (peptide mimetics), and the like, including all of the foregoing, are sometimes referred to herein as “residues.”

[0038] “Substantial degradation” refers to the degradation of the N-terminal extension, the C-terminal extension, both N- and C-terminal degradation or degradation to other regions of the melanocortin peptide by physiological enzymes and other factors, in such a manner or to a degree that side effects appear. According to one aspect, a melanocortin analog having a C-terminal extension that resists substantial degradation is one where no more than 50% of the administered peptide causes side effects and / or displays a low half-life. In some embodiments, no more than 25% of the administered peptide causes side effects and / or displays a low half-life. More preferably, in some embodiments, less than 10% of the administered peptide causes side effects and / or displays a low half-life, as compared to a melanocortin analog that lacks a C-terminal extension.

[0039] The disclosure of all publications, patents, and published patent applications listed herein are hereby incorporated by reference in their entireties, including but not limitedDocket No.: 183B-412971 -WO to U.S. Patent Nos. 8,541 ,545 and 9,534,018 and PCT Publication Nos. WO 2024 / 086381 , WO 2024 / 173905, WO 2024 / 177909, WO 2024 / 177907, WO 2025 / 123055, and WO 2025 / 151135.Non-naturally Occurring Melanocortin Analogs

[0040] Non-naturally occurring melanocortin analogs described herein may be selective for the melanocortin 4 receptor and / or melanocortin 3 receptor over other melanocortin receptors, i.e., the melanocortin 1 , melanocortin 2, and melanocortin 5 receptors. Some of the melanocortin analogs bind the melanocortin 3 receptor with greater affinity than the melanocortin 4 receptor, whereas other melanocortin analogs bind the melanocortin 4 receptor with greater affinity than the melanocortin 3 receptor. Certain melanocortin analogs bind the melanocortin 3 receptor with the same or generally similar affinity as the melanocortin 4 receptor.

[0041] The non-naturally occurring melanocortin analogs of the present technology may be full antagonists for one or more melanocortin receptors. A full antagonist may comprise a non-naturally occurring melanocortin analog having a maximum effect (Emax) agonist value of greater than or equal to 80%.

[0042] The non-naturally occurring melanocortin analogs of the present technology may be partial agonists or partial antagonists of one or more melanocortin receptor. A partial agonist or antagonist may comprise a non-naturally occurring melanocortin analog having a maximum effect Emax agonist value of less than 80%.

[0043] If a non-naturally occurring melanocortin analog’s Emax antagonist value is greater than it’s Emax agonist value, then the non-naturally occurring melanocortin analog may be classified as an agonist (e.g., a full agonist or a partial agonist). Similarly, if a non- naturally occurring melanocortin analog’s Emax agonist value is greater than it’s Emax antagonist value, then the non-naturally occurring melanocortin analog may be classified as an antagonist (e.g., a full antagonist or a partial antagonist).

[0044] The non-naturally occurring melanocortin analogs of the present technology may be one or more of (i) a full MC3R antagonist and a full MC4R antagonist; (ii) a full MC3R antagonist and a partial MC4R antagonist; (iii) a full MC3R antagonist having no MC4RDocket No.: 183B-412971 -WO agonist or antagonist activity; (iv) a full MC3R antagonist and a partial MC4R agonist; (v) a partial MC3R antagonist and a full MC4R antagonist; (vi) a partial MC3R antagonist and a partial MC4R antagonist; (vii) a partial MC3R antagonist having no MC4R agonist or antagonist activity; or (viii) a partial MC3R antagonist and a partial MC4R agonist.

[0045] The non-naturally occurring melanocortin analogs in accordance with the present technology may have structural features that impart specific properties on the analogs, such as, for example, degradation resistance, enhanced epithelial, gastrointestinal, and / or blood brain barrier transport, and binding affinity for the MC4R and / or MC3R. For example, in some embodiments, the non-naturally occurring melanocortin analogs comprise one or more of (i) blood brain barrier passage capabilities, (ii) enhanced epithelial and / or gastrointestinal transport; (iii) degradation resistance; or (iv) equipotency on MC3R and MC4R activity. In some embodiments, the non-naturally occurring melanocortin analogs comprise two or more of (i)-(iv). In some embodiments, the non-naturally occurring melanocortin analogs comprise each of (i)-(iv). Accordingly, in some embodiments, the melanocortin analogs include a stabilizing N-terminus, and / or a C-terminus that provides enhanced transport of the analog. In some embodiments, melanocortin analogs include a D-valine-D-proline (dVal-dPro) chain as their C-terminus, which may provide enhanced transport and resistance to degradation Additionally, in some embodiments, the melanocortin analogs have one or more beta hairpin (p-hairpin) and / or beta turn (p-turn) structures. In general, cyclization and D-amino acids may induce and / or stabilize beta-turns.

[0046] The presence of certain structural features may impart the non-naturally occurring melanocortin analogs of the present technology with specific binding properties. For example, inclusion of large amino acids like dNal(2’) at the R4position may result in enhanced inhibition of the melanocortin 4 and the melanocortin 3 receptors. Accordingly, melanocortin analogs having amino acids like and dNal(2’) at R4may be full antagonists on MC3R and MC4R. Additionally, smaller amino acids, such as p(F)dPhe, may confer inhibitory activity on the melanocortin analogs when Pro is included at the R3position. Such melanocortin analogs may by full antagonists on MC3R and have no activity or partial activity (agonist or antagonist) on MC4R.Docket No.: 183B-412971 -WO

[0094] The melanocortin analogs described herein may be readily synthesized by any known conventional procedure for the formation of a peptide linkage between amino acids. Such conventional procedures include, for example, any solution phase procedure permitting a condensation between the free alpha amino group of an amino acid or residue thereof having the carboxyl group or other reactive groups protected and the free primary carboxyl group of another amino acid or residue thereof having the amino group or other reactive groups protected. In an exemplary procedure, the peptides described herein may be synthesized by solid-phase synthesis and purified according to methods known in the art. Any of a number of well-known procedures utilizing a variety of resins and reagents may be used to prepare the peptides described herein.

[0095] The process for synthesizing the peptides may be carried out by a procedure whereby each amino acid in the desired sequence is added one at a time in succession to another amino acid or residue thereof or by a procedure whereby peptide fragments with the desired amino acid sequence are first synthesized conventionally and then condensed to provide the desired peptide. The resulting peptide is then cyclized to yield a cyclic peptide.

[0096] Solid phase peptide synthesis methods are well known and practiced in the art. In such methods, the synthesis of peptides can be carried out by sequentially incorporating the desired amino acid residues one at a time into the growing peptide chain according to the general principles of solid phase methods. These methods are disclosed in numerous references, including Merrifield, Angew Chem. 24:799-810 (1985) and Barany et al., The Peptides, Analysis, Synthesis and Biology, Vol. 2, Gross E. and Meienhofer J., Eds. Academic Press 1 -284 (1980).

[0097] In chemical syntheses of peptides, reactive side chain groups of the various amino acid residues are protected with suitable protecting groups, which prevent a chemical reaction from occurring at that site until the protecting group is removed. Also common is the protection of the alpha amino group of an amino acid residue or fragment while that entity reacts at the carboxyl group, followed by the selective removal of the alpha amino protecting group to allow a subsequent reaction to take place at that site. Specific protectingDocket No.: 183B-412971 -WO for solid phase synthesis methods and solution phase synthesis methods groups are known to those having ordinary skill in the art.

[0098] Alpha amino groups may be protected by a suitable protecting group, including a urethane-type protecting group, such as benzyloxycarbonyl (Z) and substituted benzyloxycarbonyl, such as p-chlorobenzyloxycarbonyl, p-nitrobenzyloxycarbonyl, p- bromobenzyloxycarbonyl, p-biphenyl-isopropoxycarbonyl, 9-fluorenylmethoxycarbonyl (Fmoc) and p-methoxybenzyloxycarbonyl (Moz); aliphatic urethane-type protecting groups, such as t-butyloxycarbonyl (Boc), diisopropylmethoxycarbonyl, isopropoxycarbonyl, and allyloxycarbonyl. Fmoc is useful for alpha amino protection.

[0099] Guanidino groups may be protected by a suitable protecting group, such as nitro, p-toluenesulfonyl (Tosyl), Z, pentamethylchromanesulfonyl (Pmc), adamantyloxycarbonyl, pentamethyldihydrobenzofuran-5-sulfonyl (Pbf) and Boc. Pmc is a useful protecting group for Arg.

[0100] Solid phase synthesis is commenced from the C-terminal end of the peptide by coupling a protected alpha amino acid to a suitable resin. Such starting material is prepared by attaching an alpha amino-protected amino acid by an ester linkage to a p- benzyloxybenzyl alcohol (Wang) resin or a 2-chlorotrityl chloride resin, by an amide bond between an Fmoc-Linker, such as p-[(R,S)-a-[1 -(9H-fluor-en-9-yl)-methoxyformamido]-2,4- dimethyloxybenzyl]-phenoxyacetic acid (Rink linker) to a benzhydrylamine (BHA) resin, or by other means well known in the art. Fmoc-Linker-BHA resin supports are commercially available and generally used when feasible. The resins are carried through repetitive cycles as necessary to add amino acids sequentially. The alpha amino Fmoc protecting groups are removed under basic conditions. Piperidine, piperazine, diethylamine, or morpholine (20- 40% v / v) in N,N-dimethylformamide (DMF) may be used for this purpose.

[0101] Following removal of the alpha amino protecting group, the subsequent protected amino acids are coupled stepwise in the desired order to obtain an intermediate, protected peptide-resin. The activating reagents used for coupling of the amino acids in the solid phase synthesis of the peptides are well known in the art. After the peptide is synthesized, if desired, the orthogonally protected side chain protecting groups may be removed using methods well known in the art for further derivatization of the peptide.Docket No.: 183B-412971 -WO

[0102] Reactive groups in a peptide may be selectively modified, either during solid phase synthesis or after removal from the resin. For example, peptides may be modified to obtain N-terminus modifications, such as acetylation, while on resin, or may be removed from the resin by use of a cleaving reagent and then modified. Methods for N-terminus modification, such as acetylation, and for C-terminus modification, such as amidation, are known in the art. Similarly, methods for modifying side chains of amino acids are well known to those skilled in the art of peptide synthesis. The choice of modifications made to reactive groups present on the peptide will be determined, in part, by the characteristics that are desired in the peptide.

[0103] The peptide may be cyclized prior to cleavage from the peptide resin. For cyclization through reactive side chain moieties, the desired side chains are deprotected, and the peptide suspended in a suitable solvent and a cyclic coupling agent added. Suitable solvents include, for example DMF, dichloromethane (DCM) or 1 -methyl-2-pyrrolidone (NMP). Suitable cyclic coupling reagents include, for example, 2-(1 H-benzotriazol-1 -yl)- 1 ,1 ,3,3-tetramethyluronium tetrafluoroborate (TBTU), 2-(1 H-benzotriazol-1 -yl)-1 ,1 ,3,3- tetramethyluronium hexafluorophosphate (HBTU), benzotriazole-1 -yl-oxy- tris(dimethylamino)phosphoniumhexafluorophosphate (BOP), benzotriazole-1 -yl-oxy- tris(pyrrolidino)phosphoniumhexafluorophosphate (PyBOP), 2-(7-aza-1 H-benzotriazol-1 - yl)-1 ,1 ,3,3-tetramethyluronium tetrafluoroborate (TATU), 2-(2-oxo-1 (2H)-pyridyl)-1 ,1 ,3,3- tetramethyluronium tetrafluoroborate (TPTU) or N,N'-dicyclohexylcarbodiimide / 1 - hydroxybenzotriazole (DCCI / HOBt). Coupling is convention initiated by use of a suitable base, such as N,N-diispropylethylamine (DIPEA), sym-collidine or N-methylmorpholine (NMM).

[0104] Following cleavage of peptides from the solid phase following their synthesis, the peptide can be purified by any number of methods, such as reverse phase high performance liquid chromatography (RP-HPLC), using a suitable column, such as a C18 column. Other methods of separation or purification, such as methods based on the size or charge of the peptide, can also be employed. Once purified, the peptide can be characterized by any number of methods, such as high performance liquid chromatograph (HPLC), amino acid analysis, mass spectrometry, and the like.Docket No.: 183B-412971 -WOSalt Forms of Non-Naturallv Occurring Melanocortin Analogs

[0150] The following examples are intended to illustrate various embodiments of the present technology. As such, the specific embodiments discussed are not to be construed as limitations on the scope of the present technology. It will be apparent to one skilled in the art that various equivalents, changes, and modifications may be made without departing from the scope of present technology, and it is understood that such equivalent embodiments, are to be included herein. Further, all references cited herein are hereby incorporated by reference in their entirety, as if fully set forth herein.Example 1: Peptide Synthesis-Generic

[0151] The non-naturally occurring melanocortin analogs described herein were synthesized by conventional procedures (e.g., solution-phase procedure, solid-phase synthesis) for the formation of a peptide linkage between amino acids. The solution-phase procedure involved a condensation between the free alpha amino group of an amino acid or derivative thereof having the carboxyl group or other reactive groups protected and the free primary carboxyl group of another amino acid or derivative thereof having the amino group or other reactive groups protected. The solid-phase synthesis utilized a variety of resins and reagents and may involve additional purification steps.

[0152] The process for synthesizing the non-naturally occurring melanocortin analogs was generally performed by a procedure as follows. Each amino acid in the desired sequence of the non-naturally occurring melanocortin analogs was added one at a time in succession to another amino acid or derivative thereof or by a procedure whereby peptide fragments with the desired amino acid sequence were first synthesized conventionally and then condensed to provide the desired peptide. In most cases, the resulting peptide was then cyclized to yield a cyclic peptide.

[0153] Solid-phase peptide synthesis was carried out by sequentially incorporating the desired amino acid residues one at a time into the growing peptide chain coupled to a solidphase support according to the general principles of solid phase methods (seeDocket No.: 183B-412971 -WOMerrifield, Angew Chem. 24:799-810 (1985) and Barany et al., The Peptides, Analysis, Synthesis and Biology, Vol. 2, Gross E. and Meienhofer J., Eds. Academic Press 1 -284 (1980)). An exemplary solid-phase synthesis of non-naturally occurring melanocortin analogs is provided below.

[0154] Initially, the C-terminal amino acid residue of the non-naturally occurring melanocortin analog was coupled to a solid-phase support, e.g., a solid-phase resin. Coupling of the C-terminal amino acid residue and the solid-phase support may be carried out according to any method know in the art. Depending on the coupling method, the alphaamine of the C-terminal amino acid residue may or may not be protected with an amine protecting group, as described below. Likewise, the carboxyl group of the amino acid residue may or may not be activated prior to coupling to the solid-phase support in order to increase its electrophilicity. Some methods of coupling rely on the formation of an ester bond between the carboxyl group of the amino acid and a reactive handle on the solid-phase resin. For example, an amino acid residue may be coupled to a p-benzyloxybenzyl alcohol resin (Wang) or a 2-chlorotrityl chloride resin via an ester linkage. Some methods of coupling rely on the formation of an aminde bond between the carboxyl group of the amino acid and a reactive handle on the solid-phase resin For example, an amino acid residue may be coupled to a benzhydrylamine (BHA) resin through an Fmoc-linker such as, for example, p- [(R,S)-a-[1 -(9H-fluor-en-9-yl)-methoxyformamido]-2,4-dimethyloxybenzyl]-phenoxyacetic acid (Rink linker) via an amide linkage.

[0155] The non-naturally occurring melanocortin analog was then synthesized by sequential amino acid addition or combination of peptide fragments. Subsequently, the peptide was cleaved from the solid-phase support and purified by methods known in the art, such as, for example, reverse phase high performance liquid chromatography (RP-HPLC) using a suitable column, such as a C18 column. Additionally, or alternatively, other methods of separation or purification were employed, including, but not limited to, methods based on the size or charge of the peptide. Once purified, the peptide was characterized by methods such as high-performance liquid chromatograph (HPLC), amino acid analysis, mass spectrometry, and the like.Docket No.: 183B-412971 -WOExample 2: Peptide Synthesis-Protecting Groups

[0156] During synthesis of the non-naturally occurring melanocortin analogs, reactive side chain groups of the various amino acid residues were protected with suitable protecting groups, which prevented undesirable chemical reaction from occurring at that site until the protecting group was removed.

[0157] Additionally, protection of the alpha amino group of an amino acid residue or fragment was performed while that entity reacting with the carboxyl group, followed by the selective removal of the alpha amino protecting group to allow a subsequent reaction to take place at that site. Specific protecting groups for solid phase synthesis methods and solution phase synthesis methods are known to those having ordinary skill in the art. Alpha amino groups were protected by a suitable protecting group, including a urethane-type protecting group, such as benzyloxycarbonyl (Z) and substituted benzyloxycarbonyl, such as p- chlorobenzyloxycarbonyl, p-nitrobenzyloxycarbonyl, p-bromobenzyloxycarbonyl, p- biphenyl-isopropoxycarbonyl, 9-fluorenylmethoxycarbonyl (Fmoc) and p- methoxybenzyloxycarbonyl (Moz); aliphatic urethane-type protecting groups, such as t- butyloxycarbonyl (Boc), diisopropylmethoxycarbonyl, isopropoxycarbonyl, and allyloxycarbonyl. Fmoc was also used for alpha amino protection. Guanidino groups, if present, were protected by a suitable protecting group, such as nitro, p-toluenesulfonyl (Tos), Z, pentamethylchromanesulfonyl (Pmc), adamantyloxycarbonyl, pentamethyldihydrobenzofuran-5-sulfonyl (Pbf) and Boc. Pmc was used as a protecting group for Arg.

[0158] Alpha aminoprotecting groups may be removed under basic conditions, such as, for example, using a solution of piperidine, piperazine, diethylamine, or morpholine (20- 40% v / v) in N,N-dimethylformamide (DMF). In synthesis methods in which alpha amino protecting groups were used, protecting groups were removed after synthesis of the peptide and before or after cleavage of the solid-phase support.Example 3: Peptide Synthesis-Additional Modifications

[0159] If necessary, the peptides were further modified to obtain N-terminus modifications, such as acetylation, while on resin, or were removed from the resin by use ofDocket No.: 183B-412971 -WO a cleaving reagent and then modified. Likewise, C-terminus modification (e.g., amidation), was performed if needed.

[0160] Additionally, the cyclized peptide structures were obtained prior to cleavage from the peptide resin. For cyclization through reactive side chain moieties, the desired side chains were deprotected, and the peptide suspended in a suitable solvent and a cyclic coupling agent added. Suitable solvents, for example DMF, dichloromethane (DCM) or 1 - methyl-2-pyrrolidone (NMP), were used for the cyclization. Suitable cyclic coupling reagents (e.g., 2-(1 H-benzotriazol-1 -yl)-1 ,1 ,3,3-tetramethyluronium tetrafluoroborate (TBTU), 2-(1 H- benzotriazol-1 -yl)-1 ,1 ,3,3-tetramethyluronium hexafluorophosphate (HBTU), benzotriazole- 1 -yl-oxy-tris(dimethylamino)phosphoniumhexafluorophosphate (BOP), benzotriazole-1 -yl- oxy-tris(pyrrolidino)phosphoniumhexafluorophosphate (PyBOP), 2-(7-aza-1 H-benzotriazol- 1 -yl)-1 ,1 , 3, 3-tetramethyluronium tetrafluoroborate (TATU), 2-(2-oxo-1 (2H)-pyridyl)-1 ,1 ,3,3- tetramethyluronium tetrafluoroborate (TPTU), N,N'-dicyclohexylcarbodiimide / 1 - hydroxybenzotriazole (DCCI / HOBt)) were also used for the cyclization. Coupling was initiated by a suitable base, such as N,N-diispropylethylamine (DIPEA), sym-collidine or N- methylmorpholine (NMM).Example 4: Biological Data

[0168] For antagonist test (384well): 5 pl of cells were mixed in the wells of an assay plate with 5 pl of a mix of the test compound at increasing concentrations for a final concentration corresponding to the historical EC80. The plates were then incubated 30 min at room temperature.

[0169] On each day of experimentation and prior to the testing of compounds, reference compounds were tested at several concentrations in duplicate (n=2) to obtain a dose-response curve and an estimated EC50 and / or IC50 values.

[0170] Reference values thus obtained for the test were compared to historical values obtained from the same receptor and used to validate the experimental session.

[0171] A session was considered as valid only if the reference value was found to be within a 0.5 logs interval from the historical value.

[0172] For replicate determinations, the maximum variability tolerated in the test was of + / -20% around the average of the replicates.Non-naturally occurring melanocortin analog grouping
