摘要
An amorphous formulation of hypocrellin A for photodynamic therapy is reported which can provide stable aqueous dispersion of such hydrophobic photosensitizers. In vitro studies have demonstrated the active uptake of amorphous formulation of hypocrellin A into the mitochondria of tumor cells. Compared with Tween-80 micelle embedded hypocrellin A, low dark-toxicity but similar light-toxicity of the amorphous one to drug impregnated tumor cells was observed. Thus, the potential of using amorphous formulation of hypocrellin A as drug delivery system for photodynamic therapy has been demonstrated.
