DB00078 - Ibritumomab


Identification
Name Ibritumomab
Accession Number DB00078 (BIOD00069, BTD00069)
Type biotech
Description Indium conjugated murine IgG1 kappa monoclonal antibody directed against the CD20 antigen, which is found on the surface of normal and malignant B lymphocytes. Ibritumomab is produced in Chinese hamster ovary cells and is composed of two murine gamma 1 heavy chains of 445 amino acids each and two kappa light chains of 213 amino acids each.
Structure
MOL SDF PDB SMILES InChI
Categories (*)
Molecular Weight 143375.5000
Groups approved
Monoisotopic Weight Not Available
Pharmacology
Indication For treatment of non-Hodgkin's lymphoma
Mechanism of action The Fab segment of the antibody targets the CD20 epitope on B-cells, allowing the radioactive yttrium to destroy the cell via production of beta particles.
Absorption Not Available
Protein binding Not Available
Biotransformation Most likely removed by opsonization via the reticuloendothelial system when bound to B cells, or by human antimurine antibody production
Route of elimination Not Available
Toxicity Not Available
Affected organisms
  • Humans and other mammals
Interactions
