GtoPdb Ligand ID: 10078

Synonyms: example 5 [WO2016046755A1]
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This compound is reported as an orally active, inverse agonist of the nuclear hormone receptor RORγt (RORC2) [2]. RORγt is a drug target that is being expoited for the treatment of autoimmune conditions, as its inhibition reduces production of pro-inflammatory IL-17. The chemical structure is claimed as Example 5 in Pfizer's patent WO2016046755A1 [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.

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.

Bioactivity Comments
Inverse agonist 66 reduces IL-17 production by human Th17 cells with an IC50 of 9.5 nM in vitro, and by mouse Th17 cells with an IC50 of 32 nM [2]. At the gene transcription level, compound 66 inhibits production of mRNAs from a number of genes that are regulated by RORγt (IL-17A , IL-17F, IL-22, IL-26, and IL-23R). Oral bioavailability was optimised (to overcome its low aqueous solubility) by formulating the compound as a spray-dried dispersion. In vivo, compound 66 demonstrated a dose dependent inhibition of ear swelling in the mouse imiquimod-induced skin inflammation model, which was mirrored by a dose-dependent reduction in IL-17A protein in ear tissue.
