GtoPdb Ligand ID: 12636

Synonyms: EN-450
Compound class: Synthetic organic
Comment: A chemoproteomic approach identified EN450 as a molecular glue type degrader of the (oncogenic) transcription factor NF-κB1 [1]. It binds covalently to an E2 ubiquitin-conjugating enzyme (most likely UBE2D1 and UBE2D4), and this initiates the formation of a ternary complex with NF-κB1 that ultimately promotes proteasome-dependent degradation of NF-κB1. This mechanism impairs viability of leukemia cells in vitro.

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.
