Cyclodextrin Dimers as Cleavable Carriers of Photodynamic Sensitizers
摘要:
Several phthalocyanines carrying hydrophobic components have been synthesized and shown to bind to a group of cyclodextrin dimers with a carbon-carbon double bond in the linker. The complexes are soluble in water. On irradiation in the presence of oxygen, the singlet oxygen produced cleaves the olefinic linkers in the complexes, resulting in precipitation of the sensitizers. This process concentrates the sensitizers in the light beam, a process that has useful potential in photodynamic therapy.

acid (RNA) specifically in tumor microenvironment. More importantly, OSPE-mediated RNA degradation is found to downregulate the expression of metastasis-related proteins, contributing to the inhibition of metastasis after treatment. Such a photoactivated and cancer-specific synergistic therapeutic action of OSPE enables complete inhibition of tumorgrowth and lung metastasis in mouse xenograft model
