Amino-phthalocyanine-mediated photodynamic inactivation of Leishmania

21 Photodynamic inactivation (PDT) of Leishmania spp. requires cellular uptake of 22 photosensitizers, e. g. endocytosis of silicon (IV)-phthalocyanines (PC) axially substituted with 23 bulky ligands. We report here that, when substituted with amino-containing ligands, the PCs 24 (PC1 and PC2) were endocytosed and displayed improved potency against Leishmania tropica 25 promastigotes and axenic...

Fluorescence imaging during photodynamic therapy of experimental tumors in mice sensitized with disulfonated aluminum phthalocyanine.

A fluorescence imaging system was used to monitor the emission of disulfonated aluminum phthalocyanine (AlS2Pc) during the photodynamic therapy (PDT) of murine tumors. Cells of the MS-2 fibrosarcoma were injected in mice in two compartments in order to cause the development of tumors in different host tissues. Two drug doses and two uptake times were considered. Moreover, the fluorescence of th...

Photodynamic Inactivation of Endopathogenic Microbiota Using Curcumin- mediated Antimicrobial Photodynamic Therapy

Root canal disinfection is one of the main factors governing success of endodontic therapy. Antimicrobial photodynamic therapy (aPDT) is presented as a promising antimicrobial therapy that can eliminate microbiota present in infected root canal systems. In this study, a series of experiments investigated the effects of aPDT on cell viability and biofilm degradation ability of endopathogenic mic...

Cellular inactivation and antitumor efficacy of a new zinc phthalocyanine with potential use in photodynamic therapy.

The aim of the present study was to evaluate the photodynamic efficacy of a novel phthalocyanine derivate 2,3,9,10,16,17,23,24-octakis[(N,N-dimethylamino) ethylsulfanyl]phthalocyaninatozinc(II) (referred here as S1) using MCF-7c3 human breast cancer cells and the LM2 adenocarcinoma subcutaneously implanted in Balb/c mice as experimental models. The S1-l-alpha-dimyristoyl-phosphatidylcholine lip...

Photodynamic Inactivation of Candida albicans by Hematoporphyrin

Aim: To evaluate the capacity of hematoporphyrin monomethyl ether 23 (HMME) in the presence of light to cause photodynamic inactivation (PDI) of C. 24 albicans. Materials & methods: HMME photoactivity was evaluated against 25 azole-susceptible and resistant C. albicans. The mechanisms by which PDI of C. 26 albicans occurred were also investigated. Results: HMME-mediated PACT caused a 27 dose-de...
