✦ Synopsis

Studies with protoporphyrin (PP) and tin protoporphyrin (SnPP) were carried out to assess the effects of tin insertion on the sites of dye localization. Fluorescence emission spectra and studies on the sites of photodamage were consistent with a concentration of PP at membrane loci. In contrast, SnPP photodamage involved an intracellular site.

Methionine-auxotrophic L1210 cells were used to study the effect of methotrexate (MTX) on methionine uptake and metabolism. MTX was shown to inhibit amino acid transport systems and cause a decrease of methionine uptake into L1210 cells. Conversely, a nonmetabolizable amino acid analogue reduced MTX

The selectivity and efficacy of photodynamic therapy (PDT) may be improved by the combined use of photosensitizers in a similar manner to the combined use of drugs in cancer chemotherapy. Two photosensitizers (haematoporphyrin derivative (HPD) and rhodamine 123 (Rh-123) were analysed which can be ir
