MODIFIED BOUGANIN PROTEINS, CYTOTOXINS AND METHODS AND USES THEREOF

摘要

Modified forms of bouganin protein are provided having biological activity and a reduced propensity to activate human T cells as compared to the non-modified bouganin protein. Also provided are T-cell epitope peptides of bouganin, and modified T-cell epitope peptides of bouganin, which have a reduced propensity to activate human T cells as compared to the non-modified T-cell epitope peptide. Also provided are cytotoxins that comprise a ligand which binds to cancer cells, and is attached to modified bouganin proteins. Also provided are methods of inhibiting or destroying mammalian cancer cells using the cytotoxins and pharmaceutical compositions for treating human cancer. ® KIPO & WIPO 2007
