Název v původním jazyce
Novel porphyrin conjugates with a potent photodynamic antitumor effect: differential efficacy of mono- and bis-b-cyclodextrin derivatives. In vitro and in vivo
Popis výsledku v původním jazyce
In the present study we investigated photosensitizing properties of two novel mono- and bis-cyclodextrin tetrakis(pentafluorophenyl) porphyrin derivatives in several tumor cell lines and in BALB/c mice bearing subcutaneously transplanted syngeneic mousemammary carcinoma, 4T1. Both studied sensitizers were localized mainly into lysosomes and were found to induce cells death by triggering apoptosis in human leukemic cells HL-60. In 4T1 and other cell lines both apoptotic and necrotic modes of cell deathoccurred dependently on drug and light doses. Mono-cyclodextrin porphyrin derivative, P(b-CD)1, exhibited stronger in vitro photodynamic efficacy than bis-cyclodextrin derivative, P(b-CD)2. However, when their efficacy was evaluated in vivo, P(b-CD)2 displayed faster tumor uptake with maximal accumulation 6 h after application leading to complete and prolonged elimination of subcutaneous tumors within 3 days after irradiation (100 J/cm2). In contrast P(b-CD)1 uptake was slower (48 h) and
