In the search of novel strategies for the treatment of cancer, photodynamic therapy (PDT) has emerged as an effective, safe for repeated use, and non-invasive method. This technique involves the use of two major non-toxic components, a photosensitizer (PS) and a visible or near-infrared (NIR) light source, combined to induce cellular damage in an oxygen-dependent or -independent manner. Macrocyclic compounds, involving porphyrin and their derivatives, represent the major class of PS agents used in PDT. However, due to the drawbacks associated with these PS, like photosensitivity, dark toxicity, and low wavelength absorbance, new classes of PS appear to be needed. This review summarizes over the recent advances in drug discovery of non-porphyrinic PS suitable as anticancer therapeutics in PDT. The different compounds are grouped by chemical classes and discussed in terms of phototoxicity, together with the critical aspects of design and structure-activity relationship.
