A general and modular synthetic route is developed for the synthesis of azidoalkylthiol molecules, which contain an amide functional group, from common and easily available precursors. SAMs (self-assembled monolayers) formed by these amide containing azidoalkylthiols are characterised by attenuated total reflectance FTIR spectroscopy, X-ray photoelectron spectroscopy, contact angle goniometry and surface enhanced Raman spectroscopy. Signature peaks are identified in the data which allows direct observation of all the functional groups on Au electrodes bearing these monolayers. The terminal azide group is functionalised with electroactive ferrocene group in situ, using "click" chemistry. An alkyne bearing heme derivative is covalently attached using the same technique resulting in O2 reducing electrodes.

Photodynamic therapy (PDT) is a promising treatment strategy for malignant and nonmalignant lesions. 5-Aminolaevulinic acid (ALA) is used as a precursor of the photosensitizer, protoporphyrin IX (PpIX), in dermatology and urology. However, the effectiveness of ALA-PDT is limited by the relatively poor bioavailability of ALA and rapid conversion of PpIX to haem. The main goal of this study was to prepare and investigate a library of single conjugates designed to coadminister the bioactive agents ALA and hydroxypyridinone (HPO) iron chelators. A significant increase in intracellular PpIX levels was observed in all cell lines tested when compared to the administration of ALA alone. The higher PpIX levels observed using the conjugates correlated well with the observed phototoxicity following exposure of cells to light. Passive diffusion appears to be the main mechanism for the majority of ALA-HPOs investigated. This study demonstrates that ALA-HPOs significantly enhance phototherapeutic metabolite formation and phototoxicity.
