An efficient five-step synthesis method was developed to obtain tritolylporphyrin and protoporphyrin IX polyamine conjugates. These compounds were composed of either one polyamine unit (spermidine or spermine) covalently tethered to monocarboxyphenyl tritolylporphyrin or two molecules of polyamines borne by protoporphyrin IX. In each compound, an aliphatic spacer arm is linked to the N4 polyamine position. Photocytotoxicity of these new compounds was evaluated against K562 human chronic myelogenous leukemia cells and compared to Photofrin II®; protoporphyrin IX polyamine conjugates exhibited much stronger photocytocicity than Photofrin II® and were shown to readily induce necrosis in treated cells.
Biological tests were realised on K562 cells.Figure optionsDownload as PowerPoint slide
