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 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.

Summary of Clinical Use Click here for help
Rivipansel is being assessed in a Phase 3 clinical trial as a potential therapy for vaso-occlusive crisis (VOC) in hospitalized patients with sickle cell disease.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
The selectins (E-selectin, L-selectin and P-selectin) are glycoprotein cell adhesion molecules implicated in inflammatory processes such as leukocyte adhesion which play a key role in VOC in sickle cell disease. Transgenic mice lacking both P- and E-selectins are protected from VOC [2], indicating the potential of these molecules for pharmaceutical inhibition. Phase II clinical trial with rivipansel in these patients sighnificantly decreased the time it took for the VOC to resolve. Rivipansel has been granted FDA orphan drug and fast track status for VOC, as the drug appears to benefit an as yet, unmet clinical need.
