  Design of a serotonin 4 receptor radiotracer with decreased lipophilicity for single photon emission computed tomography

  摘要：

  With the aim to develop a suitable radiotracer for the brain imaging of the serotonin 4 receptor subtype (5-HT4R) using single photon emission computed tomography (SPECT), we synthesized and evaluated a library of di- and triazaphenanthridines with lipophilicity values which were in the range expected to favour brain penetration, and which demonstrated specific binding to the target of interest. Adding additional nitrogen atoms to previously described phenanthridine ligands exhibiting a high unspecific binding, we were able to design a radioiodinated compound [I-125]14. This compound exhibited a binding affinity value of 0.094 nM toward human 5-HT4R and a high selectivity over other serotonin receptor subtypes (5-HTR). In vivo SPECS imaging studies and competition experiments demonstrated that the decreased lipophilicity (in comparison with our previously reported compounds 4 and 5) allowed a more specific labelling of the 5-HT4R brain-containing regions.

  Substituted diazino[c]quinolin-5(6H)-ones and -isoquinolin-6(5H)-ones, diazino[c]naphthyridin-6(5H)- and -5(6H)-ones were obtained using two synthetic routes: one-pot cross-coupling/cyclisation and two-step cross-coupling/KOH-mediated anionic ring closure. The two strategies gave yields in the same order of magnitude and their choice depends on the availability of the starting material.
