Substance Name: Abatacept [USAN:INN:BAN:JAN]
RN: 332348-12-6
UNII: 7D0YB67S97

Notes

  • A fusion protein immunoconjugate of the extracellular domain of CTLA4 and the Fc domain of human IgG1. It functions as a T-cell co-stimulation blocker that inhibits TNF-ALPHA and prevents the activation of T-LYMPHOCYTES. It is used in the treatment of RHEUMATOID ARTHRITIS.
  • BMS-188667 is comprised of two homologous glycosylated polypeptide chains of CTLA4Ig (i.e., a homodimer) of approximately 46 kDa each which are held together by one disulfide bond and non-covalent interactions.
  • NLM: Inhibits Tumor Necrosis Factor-alpha; used for Rheumatoid Arthritis; inhibits T-cell function without depleting T cells; called a selective costimulator modulator.

    NCI: A soluble fusion protein consisting of the extracellular domain of human cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) linked to a modified Fc (hinge, CH2, and CH3 domains) portion of human immunoglobulin G1 (IgG1) with immunosuppressive activity. See More (NCI Thesaurus)
