GtoPdb Ligand ID: 9028

Synonyms: Fagarasterol | Lupeol
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Oral administration of Lupeol to dextran sulfate sodium (DSS)-induced colitis mice reduced intestinal inflammation and increased survival. This was associated with decreased expression of M1-related genes and increased expression of M2-related genes. Lupeol ameliorates experimental inflammatory bowel disease, at least in part, through inhibiting M1 and promoting M2 macrophages [2]. Similar results were simultaneously published in a different journal [1]. Note there are many isomers of this structure that can be found using the "same connectivity" operator in the PubChem CID entry.

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
No direct binding targets were identified but the authors propose that Lupeol acts through a specific receptor and down-stream signaling pathways, such as p38 MAPK, inhibits IRF5 and possibly other transcription factors critical for M1 polarization, resulting in decreased expression of M1 genes and enhanced expression of M2 genes, thereby causing an M1 to M2 switch [2].
