GtoPdb Ligand ID: 14191

Compound class: Peptide
Comment: In >10% of solid tumours aberrant Wnt/β-catenin signalling is a recognised driver of resistance to immunotherapy and is associated with poor prognosis. Zolucatetide (FOG-001; Parabilis Medicines) is a first-in-class peptide that competitively inhibits formation of the β-catenin:T-cell factor (TCF) transcription complex [1]. This action disrupts Wnt signaling, and is proposed for anti-tumour potential. The peptide was created using Parabilis' proprietary Helicon™ technology. Helicons are alpha-helical peptides that are highly modified to optimise target engagement and pharmacokinetics (stability, delivery across the cell membrane). Antibody-Helicon conjugate (AHC) development is the focus of a collaboration between Parabilis and Regeneron that was announced in May 2026.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

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.
