Dani is studying the pairing of nitroaromatic compounds to nitroreductase enzymes for the generation of electrophilic intermediates known as aza-quinone methides (aQMs). Using both synthetic and enzymatic methodology she is investigating the potential of these compounds to work as biological alkylators. Results of these studies may be used in the design of novel motifs used in drug design and site specific modification.
