Hyaluronate–Peanut Agglutinin Conjugates for Target-Specific Bioimaging of Colon Cancer
Colon
cancer is one of the most common death-related cancers in
the world. For treating colon cancer, it is crucial to detect and
remove malignant lesions early. Here, we developed hyaluronate (HA)–peanut
agglutinin (PNA) conjugates for the bioimaging of colon cancer. The
HA–PNA conjugates were successfully synthesized by the coupling
reaction between aldehyde-modified HA and the N-terminal amine group
of PNA. For diagnostic imaging, rhodamine B (RhoB) was chemically
conjugated onto PNA in HA–PNA conjugates. After intraluminal
injection of HA–PNA–RhoB conjugates into tumor-bearing
mice, small-sized colon cancers could be effectively visualized by
ex vivo imaging with an in vivo imaging system (IVIS) and a two-photon
microscope. With these results taken together, we could confirm the
feasibility of HA–PNA–RhoB conjugates as a bioimaging
agent for detecting colon cancers
