Claim:
1. A peptide analog comprising: wherein P is a peptide having the amino acid sequence wherein X1 is a D-serine, α-aminoisobutyric acid (aib), 1-Amino-1-cyclobutane carboxylic acid (Acb) residue, 1-Amino-1-cyclohexane carboxylic acid (Acx); alpha-aminobutyric acid (Abu); D-alpha-aminobutyric acid (D-Abu); Aminovaleric acid (Nva); beta-cyclopropyl-alanine (Cpa); propargylglycine (Prg); Allylglycine (Alg); 2-Amino-2-cyclohexyl-propanoic acid (2-Cha); D-tertbutylglycine (D-tbg); Vinylglycine (Vg); 1-Amino-1-cyclopropane carboxylic acid (Acp); or 1-Amino-1-cyclopentane carboxylic acid (Acpe) residue; X2 is a tyrosine (Y) or lysine (K) residue; X3 is serine (S) or lysine (K) residue; X4 is serine (S), α-aminoisobutyric acid (aib), or glutamic acid (E) residue; X5 is an arginine (R) or glutamic acid (E) residue; X6 is an arginine (R) or alanine (A) residue; X7 is a glutamine (Q) or lysine (K) residue; X8 is a methionine (M), norleucine (Nle), methionine sulfoxide (m), or O-methyl-L-homoserine (o) residue; X9 is a gamma glutamic acid (γGlu) residue; X10 is a gamma glutamic acid (γGlu) residue or absent; Z1 is an optionally present protecting group that, if present, is joined to the N-terminal amino group, M is (i) a cysteine residue covalently linked to a cholesterol moiety by a hydrophilic linker, (ii) a lysine residue covalently linked to a lipid moiety by a spacer comprising one or more gamma glutamic acid residues, or (iii) a lipid moiety, wherein M is covalently linked to a C-terminal or internal amino acid of P by a spacer comprising one or more gamma-glutamic acid residues; and Z2 is an optionally present protecting group that, if present, is joined to the C-terminal carboxy group; and pharmaceutically acceptable salts thereof, wherein the peptide analog or salt thereof has a pI of less than 6.0 and is a dual GLP-1 receptor agonist and glucagon receptor agonist.
