Synthesis of Immunotoxin of Anti-CD3 Monoclonal Antibody-Bongkrekic Acid and Cytotoxic Effect Against CD3+ T Cells in Peripheral Blood Mononuclear Cells

In silico assays revealed an interaction between the carboxylic groups of BKA and the primary amine group of antibodies. The Conjugates exhibited lower cytotoxicity compared to BKA and anti-CD3 Mab individually. In vitro assays have not been able to show the specificity of the conjugate due to the anti-CD3 MAb alone exhibiting cytotoxic properties in PBMCs.
