Photoswitchable peptides

Our drug candidates are peptidic therapeutics, modified by photoisomerizable building blocks. They can toggle between two forms, inactive and active, upon irradiation with light of different wavelength. The inactive (and non-toxic) photoswitchable peptidic drugs are administered to the patients. Switching the biological activity “on” with non-thermal red light irradiation in the sites of lesions (tumors, wounds) allows avoiding side-effects in the healthy tissues.
