Uses
B7/CD28 interaction inhibitor 1 (copmound 6b) is a potent B7.1-CD28 interaction inhibitor with an IC50 of 50 nM[1].
Biological Activity
MDK 24720 (CTLA-4 inhibitor, copmound 6b) is a Cytotoxic T-Lymphocyte-Associated protein 4 (CTLA-4, CD152) inhibitor with IC50 of 50 nM for B7.1–CD28 inhibition.
in vitro
Bivalent CTLA4 homodimers bridge bivalent B7.1 homodimers to form an unusually stable signaling complex. Blocking B7/CD28 interactions with monoclonal antibodies or soluble receptors results in immunosuppression and enhanced allograft survival, while B7/CTLA-4 blockade results in enhanced antitumor immune responses. The interaction of co-stimulatory antigen molecules on T cells with B7 molecules on presenting cells plays an important role in the activation of naive T cells. Consequently, agents that disrupt these interactions should have applications in treatment of transplant rejection as well as autoimmune diseases.
