GtoPdb Ligand ID: 10094

Synonyms: compound 4b [PMID: 30216722]
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This compound is reported as a selective inhbitor of Bruton's tyrosine kinase (BTK) [2]. Compared to existing BTK inhibitors it has a novel aminotriazine scaffold. Inhibitor 4b has been advanced to preclinical studies for evaluation of its anti-inflammatory potential. This is one of the chemical structures claimed in Carna Bioscience's patent WO2015012149A1 [3]. The structure is identical to that for the INN sofnobrutinib.

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.

Immunopharmacology Comments
Inhibitor 4b is a selective BTK inhibitor that is being evaluated for preclinical anti-inflammatory efficacy [2]. Based on in vivo tests in rodents it is being considered as a lead compound for the treatment of rheumatoid arthritis. BTK activity is implicated in a number of pathologies that are driven by B-cell or macrophage activation, such as B-cell malignancies, asthma, rheumatoid arthritis, and systemic lupus erythematosus. BTK inhibitors have already proven useful in the clinic (see ibrutinib and acalabrutinib).
