E-mail: yoonil71@inje.ac.kr (I. Y.); ykshim@inje.ac.kr (Y. K. S.)Received March 14, 2011, Accepted April 8, 2011A comparative study of the photodynamic and antioxidant activities of methyl pheophorbide-a (MPa, 1) andits transition metal(II) complexes ( 2-5) is described. Four transition metal complexes (palladium(II): 2, zinc(II):3, cobalt(II): 4 and copper(II): 5) of MPa were prepared by reaction between the corresponding transition metaland 1, respectively, and were characterized by
