Fimaporfin | TPSC2a | CAS#1443547-43-0 | photosensitizer

MedKoo Cat#: 206129 | Name: Fimaporfin

Description:

WARNING: This product is for research use only, not for human or veterinary use.

Fimaporfin, also known as TPCS2a, is a potent chlorin-based photosensitizer, Fimaporfin is consisted of a mixture of three isomers A, B and C (25%,50%,25%). Fimaporfin has been developed by di-imide reduction of disulfonated tetraphenyl porphine (TPPS(2a)). The synthesized TPCS(2a) contains 3 isomers as shown by HPLC with low (<4%) inter-batch variation with respect to isomer formation, less than 0.5% (w/w) of the starting material TPPS(2a) and absorbs light at 652 nm. TPCS(2a) was found to be a clinically suitable PCI photosensitizer for photochemical activation of molecules that do not readily penetrate the cellular plasma membrane.

More Info

The absorption and fluorescence spectra of TPCS(2a) were examined in a range of solvents together with fluorescence lifetime measurements. The fluorescence lifetime of TPCS(2a) was found to be 8.5 ns in methanol, whereas non-exponential decays were observed in distilled water due to sensitiser dimerisation. The singlet oxygen quantum yield of TPCS(2a) was determined as 0.62 in deuterated methanol by direct observation of singlet oxygen phosphorescence. In a human oral squamous carcinoma (HN5) cell line, intracellular co-localisation of TPCS(2a) and Alexa488-labelled saporin, a macromolecular toxin, was observed corresponding predominantly to a lysosomal distribution. Intracellular fluorescence redistribution of TPCS(2a) and Alexa488-saporin was observed after 405 nm irradiation. Using two-photon confocal microscopy at 840 nm, and fluorescence lifetime imaging (FLIM), the lifetime was measured as 6 ns in HN5 cells. PCI using TPCS(2a) was shown to be very effective, and a synergistic increase in saporin toxicity was achieved in HN5 cells where viability was significantly reduced after light exposure compared to saporin (25 nM) treatment alone. The results demonstrate the favourable photophysical and photobiological properties of TPCS(2a) for PCI, which induces the relocalisation of a macromolecular anti-cancer toxin inside cells and significantly enhances cell death.
