title: [Determination and pharmacokinetics of photosensitizer ZnPcS2P2 uptaken by K562 cells].
abstract: The di-sulfonated di-phthalimidomethyl phthalocyanine zinc (ZnPcS2P2) was an amphiphilic photosensitizer for photodynamic therapy of cancer. According to fluorescence analytical method, extracting efficiencies of 2.0% SDS (Wt%), 1.5% Triton X-100 (phi) and DMF for ZnPcS2P2 in K562 cells were compared. The results showed that 1.5% Triton X-100 was the most efficient reagent for the first time extracting. Using 1.5% Triton X-100 as extracting reagent, the kinetic curves of cellular uptake of ZnPcS2P2 as well as LDL-ZnPcS2P2 complex by K562 cells were determined. Compared with ZnPcS2P2, the maximum cellular uptake of LDL-ZnPcS2P2 by K562 was doubled, which indicated that LDL was an effective targeting delivery vehicle for ZnPcS2P2.
