MRI CONTRAST AGENTS FOR CELL LABELING

摘要

Porphyrin compounds useful in the field of magnetic resonance imaging (MRI) as contrast agents. The compounds are relatively lipophilic porphyrins, include one or more enzyme-reactive functional groups, and are cell membrane permeable. Relatively lipophilic group(s) can be enzymatically released within a cell to produce a relatively hydrophilic porphyrin compound.
