Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: This compound is an optimised derivative of STING agonist 2 that has improved solubility and improved potency in primary cells [4]. Like agonist 2 it is one of the chemical structures claimed in GlaxoSmithKline's patent WO2017175147A1 [1]. it behaves as a cyclic dinucleotide mimic to activate the STING pathway.

SARS-CoV-2: Preclinical experimental evidence (in mice) suggests that this STING agonist may be effective in controlling infection by a range of SARS-CoV-2 variants, including B.1.351 (the beta variant [3]) [2]. The mechanistic hypothesis is that directly activating STING transiently stimulates interferon (IFN) signalling and circumvents the virus' ability to block IFN activation in infected respiratory epithelial cells, and re-establishes the innate immune response to infection.

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.
