GtoPdb Ligand ID: 12628

Compound class: Synthetic organic
Comment: TNG260 is an HDAC1 inhibitor with activity at the HDAC1/LSD1/RCOR1 (REST corepressor 1) complex. The compound reverses anti-PD1 resistance (immune evasion phenotype) that is driven by loss-of-function mutations in serine/threonine kinase 11 (STK11; LKB1). TNG260 is designed for potential to treat STK11 mutant cancers in combination with checkpoint inhibition. The chemical structure was disclosed during the 'First Disclosures of New Drug Candidates' session at the April 2023 (Orlando) meeting of the AACR.

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.
