Structure−Activity Relationships in Carboxamide Derivatives Based on the Targeted Delivery of Radionuclides and Boron Atoms by Means of Peripheral Benzodiazepine Receptor Ligands
as carriers of radionuclides and boron atoms. Some new ligands show enhanced affinity and steroidogenic activity with respect to reference compound 1 and are interesting candidates for radiolabeling and PET studies. Moreover, carborane derivative 3q, representing the first example of PBR ligand bearing a carborane cage, can be useful to explore an alternative mechanism in BNCT.

With the aim of developing new SPECT imaging agents for the translocator protein (TSPO), a small library of iodinated quinoline-2-carboxamides have been prepared and tested for binding affinity with TSPO. N,N-Diethyl-3-iodomethyl-4-phenylquinoline-2-carboxamide was found to have excellent affinity (K-i 12.0 nM), comparable to that of the widely used TSPO imaging agent PK11195. (c) 2009 Elsevier Ltd.
