Synonyms: compound 40 [PMID: 28498658] | PF-06650833 | PF06650833
PDB Ligand Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: PF-06650833 is a small molecule, reversible, potent and selective IRAK4 inhibitor identified as a clinical lead [1]. Its pharmacokinetic profile suggests it will be orally bioavailable. Structurally it is an analogue of PF-06426779. The chemical structure for the INN zimlovisertib is identical to the structure of PF-06650833.

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.

Bioactivity Comments
PF-06650833 inhibits TLR7/8 agonist R848-induced TNFα production in human peripheral blood mononuclear cells with an IC50 of 2nM [1]. Further preclinical results detailing the pharmacokinetic and ADME profiles of PF-06650833 are reported in [1]. In a kinome selectivity profile 200nM PF-06650833 completely inhibited IRAK4 activity, and inhibited the additional kinases IRAK1, MNK2, LRRK2, CLK4, and CK1γ1 by > 70%. In a more physiologically relevant screen, other than IRAK4, 200nM PF-06650833 inhibited only CK1γ2, IRAK3/M, PIPK2C, and CK1δ/ε by > 50%.
