A part of the biological activity of the TSC-CuII complexes restson their reactivity against cell reductants, as glutathione (GSH). The present paper describes the structure of the[Cu(PTSC)(ONO2)]n compound (1) (HPTSC =pyridine-2-carbaldehyde thiosemicarbazone) and its spectroscopicand magnetic properties. ESI studies performed on the reaction of GSH with 1 and the analogous [{Cu(PTSC*)(ONO2)}2] derivative (2, HPTSC* =pyridine-2-carbaldehyde 4N-methylthiosemicarbazone) show theabsence of peaks related with TSC-Cu-GSH species. However GSH-Cu ones are detected, in good agreement withthe release of CuI ions after reduction in the experimental conditions. The reactivity of 1 and 2 with cytochromec and myoglobin and their activities against HT-29 and SW-480 colon carcinoma cell lines are compared withthose shown by the free HPTSC and HPTSC* ligands.
