Effects of central metals on sugar decorated tetrakis-(4-methylthiophenyl) porphyrin considered for use in photodynamic therapy

Photodiagnosis and Photodynamic Therapy
This study focuses on the synthesis of sugar decorated porphyrins and their gold nanoparticle conjugates as photosensitizers for photodynamic therapy (PDT). Linking the sugar to the porphyrins imparted water solubility to the latter.

Supporting porphyrins on resin-beads by cyanuric chloride linker

, 2007
A straightforward procedure for supporting porphyrin-derivatives onto resin beads has been developed by reacting the commercially available 4,6-dichloro-1,3,5-triazene polymer-bound, with 5-(4-aminophenyl)-10,15,20-triphenylporphyrins as free base and as

Porphyrins with directly meso -attached disaccharide moieties: Synthesis, self-assembly and cellular study

, 2016
A series of porphyrins with directly meso-attached "sucrose" moiety by the carbon C-6′ of its "fructose" end was synthesized, and their physico-chemical and aggregation properties studied by spectroscopic (fluorescence, circular dichroism, resonance ...

New Complexes of Binaphthyl bis-Strapped Porphyrins

, 2006
Metalloporphyrin species are effective catalysts for hydrocarbon functionalizations [1]. We have developed a family of binaphthyl bis strapped porphyrins built on a tetra-aminophenylporphyrin scaffold [2].

C–C Coupling in sterically demanding porphyrin environments

Beilstein Journal of Organic Chemistry
Unlike their planar counterparts, classic synthetic protocols for C–C bond forming reactions on nonplanar porphyrins are underdeveloped. The development of C–C bond forming reactions on nonplanar porphyrins is critical in advancing this field of study ...

Spot urine porphyrins/creatinine ratio profile of healthy Brazilian individuals adjusted for personal habits

Brazilian Journal of Medical and Biological Research, 2009
Changes in urinary porphyrin excretion may be the result of hereditary causes and/or from environmental or occupational exposure. The objective of this study was to measure the amount of some porphyrins in spot urine samples obtained from volunteers ...

Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.
