Sp. Songca et al., A CONVENIENT ROUTE TO NEW FLUORINATED PHOTODYNAMIC THERAPEUTIC PHOTOSENSITIZERS BASED ON MESO-TETRA(HYDROXYPHENYL)PORPHYRINS, South African Journal of Chemistry, 50(1), 1997, pp. 40-47
A general synthetic route was developed for the synthesis of new fluor
inated tetra(hydroxyphenyl) porphyrins ,15,20-tetrakis(2-fluoro-3-hydr
oxyphenyl)porphyrin 10, 20-tetrakis(2,4-difluoro-3-hydroxyphenyl)porph
yrin 11, and 20-tetrakis(3,5-difluoro-4-hydroxyphenyl)porphyrin 12], a
nalogues of sensitisers 1-3 which are known to be active in vivo in ca
ncer photodynamic therapy.
