Chlorophyll Sensitizers in Photodynamic Therapy
Photodynamic therapy (PDT) has proved to be a viable and interesting alternative to currently used less selective methods for palliative care of cancer and, in a limited number of cases, for curative treatment. Still, in spite of impressive progress and a few approvals for clinical applications, the great potential of PDT has not yet been fully realized because of current defi ciencies of appli...
متن کاملPhotodynamics of the bacteriochlorophyll-carotenoid system. 2. Influence of central metal, solvent and beta-carotene on photobleaching of bacteriochlorophyll derivatives.
Bacteriochlorophyll (BChl) derivatives (with central Mg replaced by metal "M") ([M]-BChl with M = 2H, Mg, Zn, Pd, Cu) have been investigated for their photodynamic capacity and stability toward photodegradation in organic solvents and aqueous micellar solution. A protocol has been developed for screening new sensitizers. BChl and [Zn]-BChl are efficient sensitizers, but they are also quickly de...
متن کاملNovel water-soluble bacteriochlorophyll derivatives for vascular-targeted photodynamic therapy: synthesis, solubility, phototoxicity and the effect of serum proteins.
New negatively charged water-soluble bacteriochlorophyll (Bchl) derivatives were developed in our laboratory for vascular-targeted photodynamic therapy (VTP). Here we focused on the synthesis, characterization and interaction of the new candidates with serum proteins and particularly on the effect of serum albumin on the photocytotoxicity of WST11, a representative compound of the new derivativ...
متن کاملProtein-A-mediated targeting of bacteriochlorophyll-IgG to Staphylococcus aureus: a model for enhanced site-specific photocytotoxicity.
A model for studying the efficiency of photodynamic action with a photosensitizer placed exclusively on the bacterial cell wall has been used. Bacteriochlorophyllide molecules, conjugated to rabbit immunoglobulin G (IgG), were synthesized. The conjugated pigment bacteriochlorophyll (Bchl)-IgG bound with high specificity to protein-A residues naturally exposed on the cell wall of the bacterium S...
متن کاملV ascular targeted photodynamic therapy ( VTP )
Introduction Studies in our laboratory focus on development of vascular targeted photodynamic therapy (VTP) based on bacteriochlorophyll derivatives as photosensitizer drugs, elucidation of its mechanism of action and development of new applications for photodynamic therapy (PDT) such as treatment of Extrauterine Pregnancy (EUP). These studies are in collaboration with Prof. Avigdor Scherz Dept...
