GtoPdb Ligand ID: 14214

Synonyms: D-Trp-Aib [1] | GAL101 | MRZ-99030 [3]
Compound class: Peptide
Comment: GAL-101 (Galimedix Therapeutics) is a small bioactive peptide that reduces formation of neurotoxic amyloid β 1-42 (Aβ1-42) oligomers [1-3]. GAL-101 binds to aromatic residues in Aβ1-42 recognition interfaces during oligomer assembly and also breaks the protein's β strands [1]. This mechanism is proposed to reduce neuronal damage in Aβ-driven diseases.

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.
