Abstract

The prevalence of the gelatinases, MMP-2 and MMP-9, in many human tumors, including breast, colorectal, prostate and gastric cancer, make them an attractive target for molecular imaging. A self assembling homotrimeric triple helical peptide (THP), incorporating sequences from type V collagen with high specificity to MMP-2 and MMP-9, was previously developed. To investigate the viability of a THP for gelatinase imaging, we conjugated 5FAM to ε-amino groups of lysine flanking the hydrolysis site and subjected this substrate (THP-5FAM) to vitro analysis. The synthesis and in vitro results was presented.
