Compound class: Synthetic organic
Comment: Baricitinib is a JAK1 and 2 selective inhibitor. The compound is orally bioavailable.

SARS-CoV-2 and COVID-19: The powerful anti-inflammatory activity of baricitinib (and potentially other approved JAK inhibitors such as fedratinib, and ruxolitinib) was suggested as potential therapeutic option to combat the immunopathological effects of SARS-CoV-2 infection in patients with severe COVID-19. A number of small-medium sized clinical studies have examined the effect of short-term baricitinib (or other JAK inhibitors) treatment in hospitalised patients with confirmed COVID-19. Such short term use of this drug during the course of SARS-CoV-2 infection (7-14 days) is not anticipated to cause serious side-effects. In March 2022, data reported from the largest of the baricitinib studies (part of the University of Oxford-led RECOVERY trial) indicated that it provided clinical benefit in hospitalised COVID-19 patients, including in those already receiving other standard care immunomodulatory treatments (e.g. dexamethasone, tocilizumab) or the antiviral drug remdesivir. This made baricitinib the 4th effective COVID-19 therapy to be identified by the RECOVERY trial.

Through the application of proprietary artificial intelligence (AI) algorithms baricitinib was predicted to possess antiviral activity in addition to its known anti-inflammatory efficacy [1,9-10]. Antiviral activity is predicted to arise from inhibition of the numb-associated kinase (NAK) AAK1 which is an important regulator of clathrin-mediated endocytosis. Inhibition of AAK1 would likely reduce the ability of viruses to infect lung cells, and is being proposed as a pharmacological mechanism that warrants further investigation as a treatment for SARS-CoV-2 infection.

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 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.
