Abstract:5-(4-Carboxyphenyl)-10,15,20-tris(3-hydroxyphenyl)chlorin-PEG-Folic acid and 5-(4-carboxyphenyl)-10,15,20-tris(3-hydroxyphenyl)chlorin-PEG-NH-Boc were synthesized starting from poly(ethylene glycol)-diamine,folic acid and 5-(4-carboxyphenyl)-10,15,20-tris(3-hydroxyphenyl)chlorin. The structures of the target compounds were characterized by UV-Vis,IR,HPLC,1HNMR and MS spectra. The synthesis condition of target compound 3a was investigated by L9(33)orthogonal experiment,and found that the yield of compound 3a was the highest as the molar ratio of DCC to chlorin was 2∶1,temperature was 50℃ and reaction time was 5 d.
Key words:photosensitizer;chlorin;folic acid;poly(ethylene glycol)-diamine
