- W1990556095 abstract "A series of amphiphilic benzylidene cycloalkanes ketone photosensitizers C1-C4 with or without folate receptor-targeted agent were designed and synthesized. Their photophysical properties and in vitro photodynamic therapy (PDT) effects were studied. The results showed that all compounds exhibited appropriate lipid-water partition coefficients and high reactive oxygen yields. The introduction of the folate receptor-targeted agent had no obvious influence on the basic photophysical & photochemical properties of C2 and C4 compared to those of their corresponding prototype compounds (C1 and C3). In vitro studies were carried out using MCF-7 cells (FR+), Hela cells (FR+) and A549 cells (FR-), which represented different levels of folate receptor (FR) expression. All of C1-C4 showed low dark toxicity and superior PDT effects compared with the clinical drug PSD-007 (a mixture of porphyrins). What’s more, folate receptor-targeted photosensitizers (C2 and C4) achieved higher accumulation and more excellent PDT effects in MCF-7 cells (FR+) and Hela cells (FR+) than photosensitizers (C1 and C3) without folate receptor-targeted agent and PSD-007. The photocytotoxicity of these photosensitizers showed no obvious differences in A549 cells (FR-)." @default.
