<abstract xmlns="http://www.w3.org/1999/xhtml"> The metal complexes have a significant role in photodynamic therapy (PDT). The most common metals studied for PDT of tumors are transitional metals. In this paper we have studied the copper(II) complexes of N-salicyliden-L-glutamate. The photocytostatic effect was monitored against mouse leukemic cell line L1210. Photocytostatic effect was confirmed for [Cu(N-salicyliden-L-glutamato・2H2O]・isoquinoline (CuCIQ), but it wasn’t observed for the parental molecule [Cu(N-salicyliden-L-glutamato・2H2O]・H2O. CuCIQ had photocytotoxic effect already at 10 μM concentration. Irradiated cells (1050 mJ.cm-2, λ = 365 nm) had half the viability of the cells incubated with CuCIQ in the dark (72 h). Co-incubation of the cells with CuCIQ and ascorbic acid increased this photocytotoxic effect and this effect correlated with the elevated level of lipoperoxidation.</abstract>
