01

Identity & nomenclature

Survodutide is a lipidated synthetic peptide agonist at both the GLP-1 receptor and the glucagon receptor, built on a modified glucagon-family backbone with a branched side-chain linker.

A registry representation showing the main chain and the linker as separate sequences does not mean the substance is a mixture of two peptides. Survodutide and mazdutide are both GLP-1/glucagon dual agonists and are not interchangeable: they differ in main-chain sequence, nonstandard residue, conjugation position, linker and lipid. Shared receptor pharmacology is a classification, not chemical equivalence.

Position 2 is Ac4c, 1-aminocyclobutane-1-carboxylic acid. It is NOT Aib. The two differ by one carbon, 12.0000 Da exactly, and substituting one for the other imports the chemistry of a different peptide. The 29-residue main chain is also not the whole molecule: a gamma-Glu-Gly-Ser-Gly-Ser-Gly-Gly linker is amidated to the Lys24 side chain and carries a C18 dicarboxylic fatty acid.

03

Structural characteristics

The 29-residue main chain is glucagon-derived. Position 2 carries 1-aminocyclobutane-1-carboxylic acid (Ac4c), not the alpha-aminoisobutyric acid found in several other analogs here, with further substitutions along the chain, a C-terminal amide, and a branched linker from the lysine 24 side chain to a C18 fatty diacid. The related glucagon entry identifies scaffold ancestry; GLP-1(7-36) amide is a native receptor comparator. GLP-1 receptor activity is engineered and does not indicate GLP-1 ancestry. Zimmermann et al. (PMID 36356832) describe survodutide as made by introducing modifications into the human glucagon sequence, whereas a review by Cabri et al. (PMID 34195230) calls it an oxyntomodulin analogue; this record follows the design paper. Functional potencies at the two receptors have been reported in a single cAMP assay system containing bovine serum albumin. Those are assay-specific functional values, not equilibrium binding affinities, and protein content in the assay materially affects the apparent profile. The published values should not be restated as an invariant balanced ratio, and a full-versus-partial agonist classification independent of assay conditions is not established.

  • Ac4c at position 2
  • Lys24 side-chain branched linker
  • C18 dicarboxylic fatty-acid acylation

Terminal features: Free N-terminus, C-terminal amide at Ala29.

Analytical considerations

Confirmation requires the intact mass, the 29-residue main chain, Ac4c at position 2, conjugation at Lys24, the complete linker, the C18 diacid and the Ala29 amide. Tandem MS coverage is needed on both sides of Lys24; a backbone-only database match does not characterise the branch. A GLP-1R and GCGR cAMP panel confirms a functional profile, not molecular identity, because other dual agonists produce similar responses. For bulk powder, counterion, water and peptide content are separate measurements from chromatographic area purity.

Disagreements and mix-ups

Points where sources disagree about this compound's identity, or where a name or form is easily confused with another, as noted in this record. The discrepancy register quotes the passage for each one.

What the studies reported

Each finding describes one cited study in its stated model. These observations are specific to that study and do not establish effects in other settings.
