GtoPdb Ligand ID: 12637

Synonyms: EN-67
Compound class: Synthetic organic
Comment: EN67 is a molecular glue type protein degrader [1]. It is a derivative of EN450, and like its predecsor EN67 forms a covalent bond with the allosteric C111 residue on UBE2D E2 ubiquitin-conjugating enzymes. Direct interaction with the UBE2D2 isozyme has been demonstrated.

EN67 has been conjudated to the BRD4 inhibitor (+)-JQ1, to generate a PROTAC class degrader (named NF90), which demonstrates that E2 ubiquitin ligase components can be recruited by such molecules to promote degradation of neo-substrates, in addition to the many previously reported recruiters that target E3 components of the ubiquitin-proteasome system.

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 CDK toolkit. 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.
