GtoPdb Ligand ID: 12868

Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: The structure for civorebrutinib was obtained from proposed INN list 129 (August 2023), where it is described as Bruton's tyrosine kinase inhibitor and antineoplastic agent. It is claimed in patent WO2019091440A1 (SINOMAB Bioscience) [1]. Review of SINOMAB's online pipeline page suggests that civorebrutinib is likely their lead BTK inhibitor SN1011.

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.
