GtoPdb Ligand ID: 1152

Immunopharmacology Ligand
Compound class: Endogenous peptide in human, mouse or rat
Comment: Sequences of human, mouse and rat VIP are identical

VIP was first isolated and sequenced from pig small intestine [12,15].

As with many peptide molecules, there is ambiguity surrounding representations of the exact stereochemistry of VIP. The structure shown here does not specify stereochemistry.
Species: Human, Mouse, Rat

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.

Summary of Clinical Use Click here for help
Clinical evaluation of VIP as an inhalation therapeutic for the treatment of pulmonary hypertension in COPD patients (NCT00464932) has been completed, but there is no indication of further development. Clinical use of native VIP is limited by its short circulating half-life and its gastrointestinal side-effects caused by activation of VPAC1 receptors which are found predominantly in the gastrointestinal tract. To overcome these limitations PHASEBio have developed a congugated VIP analogue that has an extended half-life (~60 hours) and selectivity for myocardial VPAC2 receptors. Coded as PB1046 (pemziviptadil INN; VasomeraTM), this synthetic VIP has advanced to Phase 2 clinical trial for evaluation as a once-weekly injection for patients with pulmonary arterial hypertension (see NCT03556020).
In response to the SARS-CoV-2 pandemic and severe COVID-19 ARDS, PB1046 was entered into a clinical trial to evaluate its efficacy in COVID-19 patients at high risk of deterioration.
