SpletThe same results were also obtained with TPPS2a in the malignant glioma cell line U87 having a SP of ~ 0.1%. In contrast, both uptake and PDT-induced cytotoxicity was strongly enhanced for PhA when combined with FTC (P < 0.001)). Specific and efficient light-controlled killing of EGFR+/ABCG2 + MA11 cells was obtained by PCI of the targeting ... SpletSurprisingly, TPPS2a is more efficient in causing photoinduced cell death. The lethal concentration on cell viability of 50% (LC50) found for TPPS2a was ~3.5 (raw data) and ~5 (considering photosensitizer incorporation) times smaller than for CisDiMPyP. CisDiMPyP damaged mainly mitochondria and triggered short-term phototoxicity by necro-apop...
