GtoPdb Ligand ID: 9564

Abbreviated name: 3AC
Synonyms: 3 α-aminocholestane
Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: 3AC is an inhibitor of inositol polyphosphate-5-phosphatase D (INPP5D) [1], an enzyme with a role in controlling immune regulatory cell numbers in vivo. INPP5D is more commonly referred to as SHIP1. SHIP1 inhibitors are being investigated as novel agents with potential clinical application in allogeneic transplantation and the treatment of hematologic malignancies.

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.
