Description: Sonoflora 1, also known as SF1, a PDT photosensitivizer. Chemically, SF1 is an analog of chlorophyll in that its macrocycle backbone is porphyrin-based and the center of the porphyrin ring consists of a metal ion. Preclinical studies showed that SF1 had very high sonodynamic as well as photodynamic activity. The clinically tested results demonstrated positive therapeutic effects for treating patients with advanced refractory breast cancers that had failed to respond to conventional chemotherapy.

Additional Information

Sonodynamic therapy (SDT) has been developed as a complementary or alternative therapy to PDT. There are data to show that an additive effect might be obtained if SDT is combined with PDT. There are also data showing that PDT is synergistic with chemotherapeutic agents. In SDT treatment, patients first ingest a sonosensitizer, a drug that can be activated by ultrasound. This drug is then activated through the use of low-intensity ultrasound, producing a cascade of endogenous cytotoxic agents. The therapy is thus similar to PDT, except that the sensitizer is activated by ultrasound rather than by light. The body transmits ultrasound much more efficiently than light, and this is a decisive advantage when treating deeper tumors. ( Source: Integr Cancer Ther 8(3) (2009) 283)
