GtoPdb Ligand ID: 10544

Compound class: Synthetic organic
Comment: QC-01-175 is a functional degrader of pathogenic tau protein [1]. It is a bifunctional molecule that simultaneously engages tau and cereblon (CRBN; a component of the E3 ubiquitin ligase complex) to trigger tau ubiquitination and proteasomal degradation. Such molecules can be described as PROTACs (proteolysis targeting chimeras). Cereblon engagement is mediated by the probe's pomalidomide module, and tau recruitment is achieved by a variant of the tau PET tracer T807 (flortaucipir (18F)). QC-01-175 retains the tau ligand-binding capacity of the parent T807, but with reduced off-target MAO inhibition liability.

QC-01-175 is commercially available from our sponsors

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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.
