GtoPdb Ligand ID: 9616

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: POM2-C-HMBP is a synthetic, cell-permeable prodrug of the Vγ2Vδ2 effector T cell activating isoprenoid (E)-4-hydroxy-3-methyl-but-2-enyl diphosphate (HMBPP) [1]. This comound shows improved internalization into target cells compared to HMBPP. Internalization was essential for engagement of BTN3A1, and the enhanced Vγ2Vδ2 effector T cell-mediated lysis of cancer cells was BTN3A1-dependent. Note that Vγ2Vδ2 effector T cells are also known as Vγ9Vδ2 cells.

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
POM2-C-HMBP activates Vγ2Vδ2 effector T cell-mediated killing of malignant cells in vitro [1]. In these experiments, Vγ2Vδ2-mediated cell lysis is BTN3A1-dependent.
