DYE CONJUGATE IMAGING AGENTS

摘要

The present invention relates to imaging agents suitable for in vivo optical imaging, which comprise conjugates of dihydrocarbazolium dyes with biological targeting moieties, such as peptides. Also disclosed are pharmaceutical compositions and kits, as well as in vivo imaging methods. The dihydrocarbazolium dyes are functionalised with water solubilising groups and have functional groups which facilitate conjugation to biological targeting moieties.
