2-Phenyl-imidazo[1,2-<i>a</i>]pyridine Compounds Containing Hydrophilic Groups as Potent and Selective Ligands for Peripheral Benzodiazepine Receptors: Synthesis, Binding Affinity and Electrophysiological Studies
GABA A receptors. The capability of flumazenil to reduce the stimulatory effect exerted by compound 9 supports the conclusion that the modulatory effects of the examined compounds occur involving the CBR. The ability of compound 16 to increase GABA A receptor-mediated miniature inhibitory postsynaptic currents in CA1 pyramidal neurons is indicative of its ability to stimulate the local synthesis and secretion
A peripheral benzodiazepinereceptor (PBR) ligand (TZ6, 5) has been selected as receptor-mediated carrier for antitumor cisplatin-like compounds. Compound 5, containing a thiazole ring in position 2 of the imidazopyridine nucleus, is able to act as a dinitrogen chelate toward platinum. The resulting complex, cis-[PtCl2(5)], that is, compound 8, has been fully characterized by NMR techniques and has

A stable Re complex containing an imidazopyridine ligand with a high affinity for TSPO has been synthesized as a model for new 99mTc or 188/186Re-based radiopharmaceuticals to be used in SPECT diagnosis or in therapy, respectively. The newcomplex fac-[ReBr(CO)3(TZ6)], structurally characterized, showed high affinity (nanomolar concentration) for the target protein.
