摘要:
A ligand and a metal complex having the ligand are provided. The ligand and a paramagnetic metal ion form a metal complex with high stability, high relaxivity and high biocompatibility. The metal complex of the present invention is applicable to the preparation of MRI contrast agents for detecting atherosclerosis. The MRI contrast agent includes a peptide sequence specific to a matrix metalloprotease, and can be recognized by a pathological thrombocyte to target a specific site, so as to enhance the imaging contrast.

摘要:
This invention provides a novel probe, which contains a prostate peptide substrate. The probe can be used as a prostate diagnostic agent for optical imaging. An 11 amino acid peptide substrate is synthesized for specific prostate-specific antigen (PSA). This protected graft copolymer (PGC) consists of a poly-L-lysine (PL) backbone and methoxypoly(ethylene glycol) (MPEG). Two terminals of peptide substrate are bound to poly-L-lysine and Cy5.5 fluorochrome. This probe will be used as a NIR (near-infrared fluorescence) probe for optical imaging.
