A comparative study of the photophysicochemical and photodynamic activity properties of meso-4-methylthiophenyl functionalized Sn(IV) tetraarylporphyrins and triarylcorroles

Abstract

Tin(IV) complexes of a 4-methylthiophenyl functionalized porphyrin (1-Sn) and its corrole analogue (2-Sn) were synthesized so that their photophysicochemical properties and photodynamic activities against MCF-7 breast cancer cells could be compared. Singlet oxygen luminescence studies revealed that 1-Sn and 2-Sn have comparable [Formula: see text] values in DMF of 0.59 and 0.60, respectively, while the IC[Formula: see text] values after irradiation of MCF-7 cells for 30 min with a Thorlabs 625 nm LED (432 J · cm[Formula: see text] were determined to be 12.4 and 8.9 [Formula: see text]M. The results demonstrate that the cellular uptake of 2-Sn and its molar absorptivity at the irradiation wavelength play a crucial role during in vitro cytotoxicity studies.
