Research Summary:

The process of drug discovery needs to be accelerated if our society is to cope with rapidly rising numbers of cancer patients, newly unveiled mechanisms of drug resistance and the realization that cancer represents a collection of diseases that will require the tailoring of more selective therapies. Synthetic, combinatorial and genetic approaches are being applied in our laboratory to design peptide-oligonucleotide-based delivery shuttles or to re-engineer large structural templates such as bacterial toxins with the view to generating selective vehicles, imaging agents and therapies to treat cancer patients. The strategies developed in our laboratory will be applicable to other diseases.
