“…On the other hand, the singlet oxygen quantum yields of the iodine-containing complexes 34 (60–71%) were higher than those observed for the non-iodinated complexes 32 (46–49%). These experimental results are in agreement with DFT and TDDFT computational calculations [ 47 , 48 ] performed with non-substituted and iodine substituted phosphorus corrole complexes. The results demonstrated that iodine-substituted phosphorus corrole complexes, such as 34 , are good candidates to act as photosensitizers in photodynamic therapy.…”

Corroles and hexaphyrins are porphyrinoids with great potential for diverse applications. Like porphyrins, many of their applications are based on their unique capability to interact with light, i.e., based on their photophysical properties. Corroles have intense absorptions in the low-energy region of the uv-vis, while hexaphyrins have the capability to absorb light in the near-infrared (NIR) region, presenting photophysical features which are complementary to those of porphyrins. Despite the increasing interest in corroles and hexaphyrins in recent years, the full potential of both classes of compounds, regarding biological applications, has been hampered by their challenging synthesis. Herein, recent developments in the synthesis of corroles and hexaphyrins are reviewed, highlighting their potential application in photodynamic therapy.

“…An interesting behavior is the ruffling of the corrole macrocycle in the iodine substituted systems (see Figure S1). This distortion is present in the corresponding solid state structure and was previously evidenced also in other substituted phosphorus corrole complexes . The differences found for the dihedral angles between theory and experiment can be due to the fact that measured and the estimated values are obtained in two different environments.…”

The search for new dyes to be used as photosensitizers in photodynamic therapy (PDT) is a field of great interest from both experimental and theoretical viewpoints.In this study, the main photophysical properties (excitation energies, singlet-triplet energy gap, and spin orbit coupling matrix elements) of some unsubstituted and iodine substituted phosphorus corrole complexes have been determined by using density functional theory and its time-dependent formulation. Results show that these compounds can be proposed as photosensitizers in PDT. The heavy atom effects have been rationalized on the basis of El-Sayed rules.

“…Corrole PDT can activate the mitochondrial apoptotic pathway through oxidation distribution by the singlet oxygen species and thus inhibit growth of tumor cells . Mitochondria destruction plays an important role in the process of apoptosis . In the early stage of apoptosis, the mitochondrial transmembrane potential is irreversibly reduced by the oxidation damage.…”

Study of photodynamic therapy (PDT) based on corroles has become one of the most important topics in corrole chemistry. Advances in synthetic methodology have made it possible for the preparation of structurally diverse corrole photosensitizers. This review covers the recent progress in the study of corrole as a photosensitizer in the photodynamic antitumor therapy. The content is organized in three sections: cellular uptaking and localization of corrole in tumor cells; morphological changes and cytotoxicity after corrole PDT treatment; and the animal level corrole PDT test. The possible mechanism of corrole‐based PDT antitumor activity is also summarized.
