| 英文摘要 | Based on theoretical prediction of the molecular polarity, water-soluble sodium HB-14-carboxylate (SCHB) was prepared and its photosensitization activity was evaluated. SCHB shows not only very good amphiphilicity but also much stronger absorption at 620 nm than its parents. In DMSO-PBS (3:1 by volume) solution (pH 7.4) of SCHB, the photosensitization generated the serniquinone anion radicals (SCHB.-) under anaerobic condition or superoxide anion radicals (O-2(.-)) in the presence of oxygen. In the oxygenated PBS solution of SCHB, hydroxyl radicals ((OH)-O-.) were photogenerated. In addition, SCHB could also be photosensitized to generate singlet oxygen (O-1(2)) with a quantum yield about 0.26. These findings suggest that SCHB can exert photodynamic action via photosensitization. (C) 2004 Elsevier Ltd. All rights reserved. |
