Technology Overview: Porphyrin Structures and Mechanisms of Action

Porphyrin-based photodynamic therapy (PDT) agents remain at the forefront of innovation in oncological and antimicrobial therapeutics as of 2025. Porphyrins are macrocyclic compounds characterized by a core structure of four pyrrole rings linked via methine bridges, creating a highly conjugated system. This configuration endows them with strong absorption in the visible spectrum, particularly in the Soret (400–450 nm) and Q (500–700 nm) bands, which is critical for their role as photosensitizers in PDT.

Upon activation by specific wavelengths of light, porphyrin-based agents undergo intersystem crossing to a triplet excited state, facilitating energy transfer to molecular oxygen and generating reactive oxygen species (ROS), predominantly singlet oxygen. These ROS induce oxidative damage to cellular components, leading to targeted cell death—a mechanism that underpins both tumor ablation and microbial inactivation. The efficacy of this approach is closely tied to the photophysical and photochemical properties of the porphyrin structure, including absorption maxima, quantum yields, and subcellular localization.

Several generations of porphyrin-based agents have been developed and commercialized, reflecting ongoing structural refinements. First-generation agents, such as hematoporphyrin derivative (HPD), paved the way for more advanced second- and third-generation compounds with improved selectivity, reduced side effects, and enhanced phototoxicity.
