  Synthesis and in vitro characterization of novel fluorinated derivatives of the TSPO 18 kDa ligand SSR180575

  摘要：

  SSR180575 (1) is a high-affinity (0.83 nM) TSPO 18 kDa ligand belonging to the pyridazino[4,5-b]indole-1-acetamides family. Herein we describe the synthesis and in vitro characterization of two series of new fluorinated analogues. Eleven compounds (out of fifteen) displayed nanomolar to subnamolar affinities (0.30-8.1 nM) and high selectivities (Ki(CBR)/Ki(TSPO) > 10(3)). Two derivatives stand out as promising candidates for drug development or use as PET probes for in vivo neuroinflammation imaging, once fluorine-18-labelled. (C) 2015 Elsevier Masson SAS.
