Porphyrin Or Derivative Thereof Patents (Class 424/9.362)
  • Patent number: 11633505
    Abstract: [Problem] To provide a nuclear magnetic resonance diagnostic agent that has a lower toxicity to organisms and reduced side effects and yet has a site specificity toward a specific cell, tissue, organ, etc. [Solution] When ALA or an ALA derivative is administered in vivo, a metabolite thereof is accumulated in a specific cell, tissue, organ, etc. Focusing on this phenomenon, a nuclear magnetic resonance analysis was performed on a site wherein the metabolite of ALA that had been administered in vivo would be possibly accumulated. As a result, it was surprisingly found that ALA and an ALA derivative are useful as a diagnostic agent whereby the aforesaid problem can be solved.

  • Publication number: 20070014725
    Abstract: The invention relates to conjugates that consist of macrocyclic metal complexes with biomolecules and their production. The conjugates are suitable as contrast media in NMR diagnosis and radiodiagnosis as well as as agents for radiotherapy. High relaxivity is achieved by a special liganding of macrocyclic compounds, and a fine-tuning of the relaxivity is made possible.
