Immunotoxins - By creating novel gene fusions using sequences coding for antibodies and toxic peptides, it may be possible to create cytotoxic drugs or 'magic bullets' called immunotoxins. These drugs will attack specific targets in, the patient. Some success in this direction has already been achieved in the synthesis of an immunotoxin using a toxic peptide which has properties similar to those of melittin.

Immunotoxins, are conjugates of cell binding antibody or antigen, covalently bound to a plant or a bacterial toxin, so that when an immunotoxin is supplied to a patient, the antibody or antigen helps in recognition of the target cells to be killed and the toxin component. helps in killing the cells, which maybe harmful being cancerous.
