Synthesis, physical–chemical properties and in vitro photodynamic activity against oral cancer cells of novel porphyrazines possessing fluoroalkylthio and dietherthio substituents
摘要:
Novel porphyrazines possessing fluoroalkylthio and dietherthio peripheral substituents were synthesized and tested from the peripheral substituent effects on their physical-chemical properties, including metal binding abilities and solvatochromic effects. Two porphyrazines were subjected to singlet oxygen generation measurements using 1,3-diphenylisobenzofuran as a singlet oxygen scavenger and examined in vitro towards oral cancer cells. Biological investigation performed on two human squamous carcinoma cell lines derived from the tongue (HSC-3) and from the buccal mucosa (H413) revealed moderate activity and selectivity of novel magnesium(II) porphyrazine possessing peripheral 4-fluorobutylthio substituents.
