Fungi account for billions of infections worldwide. The second most prominent causative agent for fungal infections is Candida albicans (C. albicans). As strains of fungi become resistant to antifungal medications, new treatment modalities must be investigated to combat these infections. One approach is to employ photodynamic therapy (PDT). PDT utilizes a photosensitizer, light, and cellular O2 to produce reactive oxygen species (ROS), which then induce oxidative stress resulting in apoptosis. Silicon phthalocyanine Pc 4 is a photosensitizer that has exhibited success in clinical trials for a myriad of skin diseases. The hydrophobic nature of Pc 4, however, poses significant formulation and delivery challenges in the use of this therapy. To mitigate these concerns, a drug delivery vehicle was synthesized to better formulate Pc 4 into a viable PDT agent for treating fungal infections. Utilizing poly(amidoamine) dendrimers as the framework for the vehicle, ∼13% of the amine chain ends were PEGylated to promote water solubility and deter nonspecific adsorption. In vitro studies with C. albicans demonstrate that the potency of Pc 4 was not hindered by the dendrimer vehicle. Encapsulated Pc 4 was able to effectively generate ROS and obliterate fungal pathogens upon photoactivation. The results presented within describe a nanoparticulate delivery vehicle for Pc 4 that readily kills drug-resistant C. albicans and eliminates solvent toxicity, thus, improving formulation characteristics for the hydrophobic photosensitizer.
