GtoPdb Ligand ID: 14495

Compound class: Peptide
Comment: CID-078 is an orally bioavailable macrocyclic peptide molecule, optimised for clinical application from the experimental macrocycle CIRc-014. Like its parent, CID-078 disrupts the protein-protein interactions between cyclins A and B and their cognate cyclin-dependent kinases (CDKs), as an anti-tumpour mechanism. The peptide binds to the same RxL motif within the conserved hydrophobic patch on the surface of the cyclins as CIRc-014.

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.
