GtoPdb Ligand ID: 8011

Synonyms: KU 0060648
Compound class: Synthetic organic
Comment: KU-0060648 is a dual inhibitor of DNA dependent protein kinase (DNA-PK) and the phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) α, β and δ subunits. This compound is an analogue of NU-7441 with improved solubility and potency, and additional activity against PI3Ks [1]. This is compound 39 in Cano et al. (2013) [1].

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

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.

Mechanism Of Action and Pharmacodynamic Effects Click here for help
DNA-dependent protein kinase (DNA-PK) activity is essential for repair of DNA double-strand breaks [5]. Inhibition of DNA-PK sensitises cells to chemo- or radio-therapy agents [2,4], leading to increased DNA damage being induced by these types of cancer therapies. DNA-PK is a member of the phosphatidylinositol (PI) 3-kinase related kinase (PIKK) family involved in the signalling of cellular stress responses, which also includes the mammalian proteins ATM, ATR, mTOR and hSMG1 [2,6]. By inhibiting DNA-PK and PI3K activity, KU-0060648 sensitises tumour cells to DNA damaging chemotherapeutics and increases cell death [3].
