Abstract

Abstract: The complexes of meso-tetra(4-N-R-pyridyl)porphyrin(R=CH₃, PhCH₂) with Cu(Ⅱ) (CuTMPyP and CuTBPyP) were synthesized by heterogeneous metal insertion reaction. The improved method is advangeous in simplicity and having good yield. Both comple xes showed a distinct O₂^-· scavenging effect and some protective effects on hemoglobin of human erythrocyte in the system of O₂^-· generating riboflavin on irradiation.

Key words: copper porphyrin complex, synthesis, peroxide anion radical, scavenging effect, hemoglobin
