Immunopharmacology Ligand
Compound class: Peptide
Comment: BMS-986238 is a macrocyclic peptide that inhibits programmed death-ligand 1 (PD-L1) [3]. It was designed as an alternative to anti-PD-L1 monoclonal antibodies and is a preclinical lead. Related structures are claimed in Bristol-Myers Squibb's patent WO2016077518A1 [1] with thioether peptide synthetic procedures described in [2].

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.
