- immunotoxin CMD-193
A humanized immunotoxin directed against the Lewis Y antigen conjugated with calicheamicin, a hydrophobic enediyne antibiotic, with potential antineoplastic activity. CMD193 binds to the Lewis Y antigen, a tetrasaccharide expressed on the cell surfaces of many tumor cell types. Upon binding, CMD-193 is internalized, thereby delivering the attached calicheamicin to Lewis Y antigen-expressing tumor cells. Calicheamicin binds non-covalently to the minor groove of DNA and prompts conformational changes and DNA oxidation, thereby inhibiting DNA synthesis and inducing apoptosis. Check for active clinical trials using this agent. (NCI Thesaurus)
