Abstract

Conjugates of trichothecenes and agents that bind to a defined population of cells are disclosed. Preferred are conjugates of trichothecene molecules with polyclonal or monoclonal antibodies or fragments thereof that recognize antigens that are present only on tumor cells or are augmented in their expression on tumor cells as compared to normal tissues. Trichothecene molecules are coupled to the agent through non-covalent and covalent linkages, such as peptide bonds, disulfide bonds, thioester bonds, or thioether bonds. Methods for reducing intoxification in a recipient of a trichothecene and an agent and for producing a trichothecene conjugate with improved solubility are also disclosed.
