`
`(57) Abstract: The invention relates to GLP-1 receptor agonist compounds with a modified N- terminus. The compounds are of
`the formula Chem. 1: Y-Z-P, wherein P represents a fragment of a GLP-1 receptor agonist peptide lacking the two N-terminal
`amino acid residues; and Y-Z represents novel His-Ala mimetics. Examples of GLP-1 receptor agonist compounds are derived
`from human GLP-1 (7-37), exendin-4(1-39), or GLP-1 A (1-37). The invention also relates to derivatives of these compounds, in
`particular compounds with one or more albumin binding side chains capable of protracting the duration of action in vivo of these
`compounds. The peptides and derivatives of the invention have a good potency, a protracted pharmacokinetic profile, are stable
`against degradation by gastro intestinal enzymes, and/or have a high oral bioavailability. These properties are of importance in the
`development of GLP-1 receptor agonist compounds for subcutaneous, intravenous, and/or in particular oral administration. The
`invention also relates to intermediate products for use in the preparation of the GLP-1 receptor agonist compounds of the inven(cid:173)
`tion.

`The term "peptide", as e.g. used in the context of the GLP-1 receptor agonist
`
`peptides of the invention, refers to a compound which comprises a series of amino acids
`
`5
`
`intereconnected by amide (or peptide) bonds.
`
`In a particular embodiment the peptide is to a large extent, or predominantly,
`
`composed of amino acids interconnected by amide bonds (e.g., at least 50%, 60%, 70%,
`
`80%, or at least 90%, by molar mass). In another particular embodiment the peptide consists
`
`of amino acids interconnected by peptide bonds.
`
`10
`
`The peptides of the invention comprise at least five constituent amino acids
`
`connected by peptide bonds. In particular embodiments the peptide comprises at least 10,
`
`preferably at least 15, more preferably at least 20, even more preferably at least 25, or most
`
`preferably at least 28 amino acids.
`
`In particular embodiments, the peptide is composed of at least five constituent
`
`15

`In a still further particular embodiment the peptide consists of amino acids
`
`interconnected by peptide bonds.
`
`Amino acids are molecules containing an amine group and a carboxylic acid group,
`
`and, optionally, one or more additional groups, often referred to as a side chain.
`
`25
`
`The term "amino acid" includes proteogenic amino acids (encoded by the genetic
`
`code, including natural amino acids, and standard amino acids), as well as non-proteogenic
`
`(not found in proteins, and/or not coded for in the standard genetic code), and synthetic
`
`amino acids. Thus, the amino acids may be selected from the group of proteinogenic amino
`
`acids, non-proteinogenic amino acids, and/or synthetic amino acids.
`
`30

`
`A "GLP-1 receptor agonist peptide" is a peptide as defined above, and also a GLP-1
`
`receptor agonist as defined above.
`
`The peptides of the invention are GLP-1 receptor agonist peptides.
`
`Additional examples of GLP-1 receptor agonist peptides are the following known
`
`compounds: Human GLP-1(7-37), exendin-4(1-39), exendin-3(1-39), and GLP-1A(1-37).
`
`10
`
`In a particular embodiment, the GLP-1 receptor agonist compound of the invention
`
`may be derived, or is derivable, from any one or more of these known GLP-1 receptor
`
`agonist peptides.
`
`The term "fragment" as it refers to a GLP-1 receptor agonist peptide means a
`
`peptide which is shorter than the peptide referred to.
`
`15
`
`In a particular embodiment corresponding to the definition of group P in formula I,
`
`the fragment lacks the two N-terminal amino acids as compared to the corresponding full(cid:173)
`
`length peptide being a GLP-1 receptor agonist.
`
`In another particular embodiment this particular fragment is not in itself a GLP-1
`
`receptor agonist, due to a i) substantial, ii) preferably almost complete, or iii) more preferably
`
`20
`
`for all practical purposes complete, loss of biological activity (i.e., GLP-1 receptor agonism).
`
`Particular examples of P (fragments of a GLP-1 receptor agonist peptide lacking the
`
`two N-terminal amino acid residues) are the following: GLP-1 (9-37), exendin-4(3-39), and
`
`GLP-1A(3-37), which are included in the appended sequence listing as SEQ ID NO: 1, SEQ
`
`ID NO: 2, and SEQ ID NO: 3, respectively. Another example of Pis exendin-3(3-39) which is

`
`Therefore, generally, any reference herein to an amino acid residue number or a
`
`position number in the context of the peptides of SEQ ID NO: 1, 2, or 3 or analogues thereof
`
`is to the sequence starting with Glu at position 9, Glu at position 3, or Asp at position 3,
`
`respectively; and ending with Gly at position 37, Ser at position 39, or Ser at pas. 37,
`
`respectively.
`
`10
`
`Additional particular examples of P are analogues of SEQ ID NO: 1, SEQ ID NO: 2,
`
`and/or SEQ ID NO: 3.
`
`An "analogue" as used herein in the context of SEQ ID NO: 1, 2, or 3 refers to a
`
`peptide, or a compound, which is a variant of any one or more of SEQ ID NO: 1, 2, or 3.
`
`In a particular embodiment, the analogue of SEQ ID NO: 1 refers to a modification of
`
`15
`
`SEQ ID NO: 1 in which a number of amino acid residues have been exchanged as compared
`
`to SEQ ID NO: 1. These exchanges, or modifications, may represent, independently, one or
`
`more amino acid substitutions, additions, and/or deletions. Additions at the N-terminus are,
`
`however, preferably excluded. Analogues of SEQ ID NO: 2, and SEQ ID NO: 3 are defined
`
`similarly, by analogy to the definition of analogues of SEQ ID NO: 1.
`
`20
`
`Analogues may be described by reference to a reference sequence, the number of
`
`the amino acid residue in the reference sequence corresponding to the one which is
`
`modified, i.e., its position, and to the actual modification.
`
`In particular embodiments, the reference sequence is i) GLP-1(9-37) (SEQ ID NO:
`
`1); ii) exendin-4(3-39) (SEQ ID NO: 2); or iii) GLP-1A(3-37) (SEQ ID NO: 3).

`
`The following are non-limiting, illustrative examples of suitable analogue

`nomenclature, as used herein:

`
`analogue in which the alanine at position 30 has been substituted with glutamic acid, the
`
`arginine at position 36 has been substituted with lysine, and a glutamic acid has been added
`
`at the C-terminus, viz. at position 38; and
`N3-{2-[2-(1 H-lmidazol-4-yl)-methylcarbamoyl]-2-methyl-propionyl}-
`[Arg 17,Arg20,Arg 33,Lys 38]GLP-1A(3-37)-peptide is a GLP-1 receptor agonist peptide of the
`
`5
`
`invention derivable from GLP-1A(3-37) (SEQ ID NO: 3), i.e. Pin Chem. 1 is an analogue of
`
`SEQ ID NO: 3, viz. the analogue in which the lysines at position 17, 20, and 33 have been
`
`substituted with arginine, and a lysine has been added at the C-terminus, viz. at position 38.
`
`This peptide, by the way, is also derivable from SEQ ID NO: 1, and it can therefore
`
`10
`
`also be designated as analogue (17T, 18Q, 19Q, 21 D, 22E, 23R, 26R, 30D, 331, 34N, 36G,
`
`37P, 38S, 39R, 40E, 411,421, 43S, 44K) of GLP-1(9-37) (SEQ ID NO: 1), having {2-[2-(1H(cid:173)
`lmidazol-4-yl)-methylcarbamoyl]-2-methyl-propionyl}- attached to the N-terminus, N9
`
`.
`
`As another example, a GLP-1 receptor agonist peptide of the invention which
`
`"comprises at least one of the following substitutions as compared to GLP-1 (9-37) (SEQ ID
`
`15
`
`NO: 1): 18K; 22E; 30E; 31H; 34Q,R; 36K; 37K; and/or38E" refers to a GLP-1 receptor
`
`agonist peptide in which P of Chem. 1 is considered an analogue of SEQ ID NO: 1, which
`
`analogue has a lysine at position 18, a glutamic acid at position 22, a glutamic acid at
`
`position 30, a histidine at position 31, a glutamine at position 34, a lysine at position 36, a
`
`lysine at position 37, and/or a glutamic acid at position 38, and which analogue may
`
`20
`
`comprise further modifications as compared to SEQ ID NO: 1.
`
`As is apparent from the above examples, amino acid residues may be identified by
`
`their full name, their one-letter code, and/or their three-letter code. These three ways are fully
`
`equivalent.
`
`The expressions "a position equivalent to" or "corresponding position" may be used
`
`25
`
`to characterise the site of modification in a modified GLP-1 receptor agonist peptide
`
`sequence by reference to any one or more of SEQ ID NO: 1, 2, or 3. Equivalent or
`
`corresponding positions, as well as the number of modifications, are easily deduced, e.g. by
`
`simple handwriting and eyeballing; and/or a standard protein or peptide alignment program
`
`may be used, such as "align" which is a Needleman-Wunsch alignment. The algorithm is
`
`30
`
`described in Needleman, S.B. and Wunsch, C.D., (1970), Journal of Molecular Biology, 48:
`
`443-453, and the align program by Myers and W. Miller in "Optimal Alignments in Linear
`
`Space" CABIOS (computer applications in the biosciences) (1988) 4:11-17. For the
`
`alignment, the default scoring matrix BLOSUM50 and the default identity matrix may be
`
`used, and the penalty for the first residue in a gap may be set at -12, or preferably at -10, and
`
`35
`
`the penalties for additional residues in a gap at -2, or preferably at -0.5.

`
`This algorithm may also suitably be used for determining the degree of identity of
`
`the P-group of a GLP-1 receptor agonist peptide of the invention to each of SEQ ID NO: 1, 2,
`
`and 3, e.g. with a view to determining which of these three sequences has the highest
`
`percentage of identity to the P-group in question, and thus for determining the number of
`
`5
`
`amino acid residues that have been exchanged as compared to the closest related sequence
`
`of SEQ ID NOs: 1-3 (the one with the highest percentage of identity). If the percentages of
`
`identity of a given P group of a GLP-1 receptor agonist of the invention to SEQ ID NO: 1, 2,
`
`and 3, respectively, should happen to be the same, any of those having the same highest
`
`percentage of identity may be used for the determination.
`

`
`An example of such alignment is inserted hereinbelow, in which sequence no. 1 is
`
`SEQ ID NO: 1, and sequence no. 2 is SEQ ID NO: 3:

`
`The above alignment is just for illustration, as typically an analogue of one of SEQ
`
`ID NOs: 1, 2, or 3 will be compared with either of these reference sequences.
`
`In case of analogues comprising non-natural amino acids such as Imp, and/or Aib
`
`30
`
`being included in the sequence, these may, for alignment purposes, be replaced with X. If
`
`desired, X can later be manually corrected.
`
`Derivatives
`
`The terms "derivative" as used herein in the context of the GLP-1 receptor agonist
`
`35
`
`peptides of the invention means a chemically modified peptide or analogue, in which one or
`
`more substituents have been covalently attached to the peptide. The substituent(s) may also
`
`be referred to as side chain(s). In a particular embodiment, the derivative of the invention has
`
`one side chain. In another particular embodiment it has two side chains. For the purpose of
`
`this definition, the group Y-Z- of formula I is preferably not considered a substituent/side
`
`40
`
`chain.

`
`WO 2011/073328
`
`PCT /EP2010/069929
`
`11
`
`In particular embodiments, the side chain has at least 10 carbon atoms, or at least
`
`15, 20, 25, 30, 35, 40, or at least 43 carbon atoms. In further particular embodiments, the
`
`side chain may further include at least 5 hetero atoms, in particular O and N, for example at
`
`least 7, 9, 10, 12, 15, 17, or at least 20 hetero atoms, such as at least 1, 2, 3, or 4 N-atoms,
`
`5
`
`and/or at least 3, 4, 6, 9, 12, 13, or 15 O-atoms.
`
`Non-limiting examples of GLP-1 receptor agonist derivatives include heterologous
`
`fusion proteins or conjugates of the GLP-1 receptor agonist peptides of the invention, with
`
`e.g. the Fe portion of an immunoglobulin such as lgG, with human albumin, with antibodies
`
`such as a glucagon binding antibody heavy chain variable region, or with fragments or
`
`10
`
`analogues of any of these (see, e.g., US 2007/0161087, WO 2005/058958, and WO
`
`2007/124463 A2). Additional examples include PEGylated peptides (see, e.g., WO
`
`2005/058954, WO 2004/093823, and WO 2006/124529), as well as acylated peptides (see,
`
`e.g., WO 98/08871, WO2005/027978, WO 2006/097537, and WO 2009/030771).
`
`In a preferred embodiment, the side chain is capable of forming non-covalent
`
`15
`
`aggregates with albumin, thereby promoting the circulation of the derivative with the blood
`
`stream, and also having the effect of protracting the time of action of the derivative, due to
`
`the fact that the aggregate of the derivative and albumin is only slowly disintegrated to
`
`release the active pharmaceutical ingredient. Thus, a preferred substituent, or side chain, as
`
`a whole may be referred to as an albumin binding moiety.
`
`20
`
`In another particular embodiment, the albumin binding moiety comprises a portion
`
`which is particularly relevant for the albumin binding and thereby the protraction, which
`
`portion may accordingly be referred to as a protracting moiety. The protracting moiety may
`
`be at, or near, the opposite end of the albumin binding moiety, relative to its point of
`
`attachment to the peptide.
`
`25
`
`In a still further particular embodiment, the albumin binding moiety comprises a
`
`portion in-between the protracting moiety and the point of attachment to the peptide, which
`
`portion may be referred to as a linker, linker moiety, spacer, or the like. The presence of a
`
`linker is optional; hence if no linker is present the albumin binding moiety may be identical to
`
`the protracting moiety.
`
`30
`
`In particular embodiments, the albumin binding moiety and/or the protracting moiety
`
`is lipophilic, and/or negatively charged at physiological pH (7.4).
