Synonyms: SGN-CD33A
Immunopharmacology Ligand
Compound class: Antibody
Comment: Vadastuximab talirine (SGN-CD33A; Seattle Genetics) is an humanized anti-CD33 antibody-drug conjugate (ADC) which delivers a toxic payload to CD33 +ve cells [1]. Talirine is a pyrrolobenzodiazepine (PBD) dimer (PubChem CID 45257190), which is a DNA crosslinking agent, causing DNA damage and ultimately apoptosis of targeted cells. Talirine is conjugated to engineered Cys residues in the antibody via a cathepsine B cleavable linker.
Annotated peptide sequences for this antibody are available from its IMGT/mAb-DB record.
