Corrole-based photodynamic antitumor therapy

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.
