摘要
In this work we report the synthesis of a set of labeled ligands targeting the human 5-HT6, receptor (h5-HT6R). Among the synthesized compounds, fluorescent probe 10 (K-i = 175 nM and Phi(f) = 0.21 and biotinylated derivative 15 (K-i = 90 nM) deserve special attention because they enable direct observation of the h5-HT6R in cells. Thus, they represent the first molecular probes for 5-HT6R visualization. These results are the starting point for introducing a variety of tags in these or other 5-HT6R ligand scaffolds aimed at the development of optimized probes with tailored profiles in terms of fluorescence, affinity, or selectivity.
