Our research has identified a couple of near-infrared (NIR) heptamethine indocyanine dyes exhibiting preferential tumor accumulation property for in vivo imaging. On the basis of our foregoing work, we describe here a preliminary structure-activity relationship (SAR) study of 11 related heptamethine indocyanine dyes and several essential requirements of these structures for in vivo tumor-targeted imaging.
