An I6P7 peptide modified fluorescent probe for bio-imaging?
New Journal of Chemistry Pub Date: 2018-12-04 DOI: 10.1039/C8NJ04255A
Abstract
The I6P7 peptide was proved to specifically bind to the interleukin-6 receptor, which can be exploited as an effective tumor-targeting moiety. Herein, a novel tumor-targeting fluorescent probe (DMP) conjugated with the I6P7 peptide was designed and synthesized. This probe was validated to possess valuable photophysical properties. The biocompatibility was evaluated by investigating its cytotoxicity on HUVEC and U87 cells, respectively. The tumor cell affinity has been confirmed by bio-imaging of this probe on different human cancer cells (U87, A549 and MCF-7 cells) and normal cells (HUVEC cell). The probe demonstrates low cytotoxicity, high tumor cell affinity and favorable mitochondria-targeting capability. Overall, these results revealed that DMP can serve as an important fluorescent probe for tumor-targeted bio-imaging.
