A compound comprising a target cell specific portion and a cytotoxic portion, characterised in that the cytotoxic portion of the compound is a constitutively active caspase or has the same apoptosis-inducing activity as a caspase. Alternatively, the invention provides a compound comprising a mediator portion and a cytotoxic portion, characterised in that the cytotoxic portion of the compound is a constitutively active caspase or has the same apoptosis-inducing activity as a caspase. Preferably, the cytotoxic portion is a constitutively active caspase-3, caspase-6 or caspase-7, and the target cell specific portion is and antibody specific for a tumour cell antigen, such an HMFG-1 antibody. The invention further provides nucleic acids encoding the compounds of the invention, and the use of such compounds in medicine, such as in the treatment of cancer. |
