  A New Generation of Radiofluorinated Pyrimidine-2,4,6-triones as MMP-Targeted Radiotracers for Positron Emission Tomography

  摘要：

  Radiolabeled C-5-disubstituted pyrimidine-2,4,6-triones have recently been suggested by our group as a class of potent matrix metalloproteinase (MMP) targeted radiotracers that can noninvasively visualize activated MMPs by means of positron emission tomography (PET). MMPs belong to the zinc- and calcium-dependent endopeptidases which are involved in the proteolytic degradation of components of the extracellular matrix (ECM) but also are capable of processing and releasing bioactive molecules such as growth factors, proteinase inhibitors, and cytokines. Locally increased levels of activated MMPs modulate and contribute to the progression of various diseases, such as cancer, atherosclerosis, stroke, arthritis, and others. Therefore, activated MMPs are suitable biological targets for the specific and noninvasive visualization of aforementioned pathologies in vivo. On the basis of our recent results, we here describe a series of new fluorinated pyrimidine-2,4,6-triones of the second generation with maintained MAP inhibition potencies (IC50 = 4-605 nM), which are fine-tuned toward more hydrophilic versions, and show the improved biodistribution behavior of one selected radiofluorinated pyrimidine-2,4,6-trione by means of small-animal PET.
