GtoPdb Ligand ID: 9043

Synonyms: ARN-509 | ARN509 | Erleada® | JNJ-56021927
Approved drug
apalutamide is an approved drug (FDA (2018), EMA (2019))
Compound class: Synthetic organic
Comment: Apalutamide is a novel androgen receptor (AR) antagonist (antiandrogen) that is approved as a treatment for castration-resistant prostate cancer (CRPC) [3]. This compound (91) was discovered in a structure/activity relationship-guided medicinal chemistry program designed to identify antiandrogens devoid of agonistic activity in the setting of androgen receptor overexpression [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.

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.

Summary of Clinical Use Click here for help
Apalutamide (using research codes ARN-509 and JNJ-56021927) was evaluated in several Phase 3 clinical trials in prostate cancer patients. As a result of positive clinical outcomes (see NCT01946204 results in Smith et al. (2018) [4]), the US FDA approved use of apalutamide for the treatment of non-metastatic castration-resistant prostate cancer in February 2018. This approval was expanded in September 2019 to include treatment of metastatic castration-sensitive prostate cancer. Click here to link to ClinicalTrials.gov's complete list of apalutamide trials.
