of our search for new ligands acting on benzodiazepinereceptors among the fused 2-thiohydantoin derivatives, a series of 5-substituted imidazo[2,1-b]thiazepines was synthesized and investigated in radioligand binding studies at the benzodiazepinebinding site of GABA(A) receptors in rat brain cortical membranes. Among ortho-substituted 5-arylidene-imidazo[2,1-b]thiazepines compounds could be identified

Differently substituted 5-arylidene-2-thiohydantoins (2 a - f) were studied electrochemically in benzonitrile with 0.1 M tetra-n-butylammonium-perchlorate as supporting electrolyte using DC-, cyclic voltammetry (CV), coulometry and controlled potential electrolysis (CPE). These compounds are oxidized in a one two-electron transfer process or in irreversible two successive one-electron processes to the corresponding diradical, which simaltaneously reacts with the solvent to regenerate the starting species. On the other hand the reduction products are the 5-arylidene-4-imidazolidinone-2-thiols.
