Polyamine conjugates of meso-tritolylporphyrin and protoporphyrin IX: potential agents for photodynamic therapy of cancers.

, 2006
International audienceAn 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
