Synonyms: ZP-1848 | ZP1848
Compound class: Peptide
Comment: Glepaglutide (ZP1848, Zealand Pharma) is a long-acting human glucagon like peptide-2 (GLP-2) analogue with a C-terminal hexa-lysine addition.
The wild type peptide sequence is
HADGSFSDEMNTILDNLAARDFINWLIQTKITD, compared to the glepaglutide sequence which is HGEGTFSSELATILDALAARDFIAWLIATKITDKKKKKK (the hexa-lysine is inderlined).
GLP-2 receptor agonists have therapeutic potential in clinical indications with compromised absorptive capacity at the intestinal mucosa, such as in short bowel syndrome. GLP2 analogues have been designed to be less susceptible to enzymatic cleavage and renal clearance and hence have an improved circulating half-life compared to the endogenous peptide. Teduglutide is already approved but has a once-daily injection regimen, so longer-acting analogues are still of development interest.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Bioactivity Comments
In vitro, glepaglutide is less potent and less selective at the GLP-2 receptor than apraglutide and teduglutide [1]. The elimination half-lives (in a rat PK model) of human glucagon-like peptide 2, teduglutide, glepaglutide, and apraglutide are 6.4, 19, 16, and 159 minutes, respectively.
