New chalcogen-nitrogen π-heterocycles covering 3,1,2,4-benzothiaselenadiazines, 1,3,2,4-benzodithiadiazines and 1,2,4,3,5-benzotrithiadiazepines were synthesized via the electrophilic cyclization of compounds Ar-NSN-SiMe3 under the action of SeCl2, SeCl4/FeCp2, SCl2 and S2Cl2. Heterocycles obtained were thermolyzed into persistent 2,1,3-benzothiaselenazolyls and 1,2,3-benzodithiazolyls (Herz radicals), which were characterized using EPR spectroscopy and DFT calculations. Reaction of the archetypal 3,1,2,4-benzothiaselenadiazine with SCl2 afforded 2,1,3-benzothiaselenazolium chloride (Herz salt), whereas that of sterically hindered 1,3,2,4-benzodithiadiazine resulted in a complex of the corresponding Herz salt with unexpected carbocycle-chlorinated and non-chlorinated 3,3-dioxides of the starting material, which is a rare example of a molecular complex involving a Herz cation. Formation of the dioxides can be explained through intermediate participation of the benzodithiadiazine radical cation. Hydrolysis of 3,1,2,4-benzothiaselenadiazine or 1,3,2,4-benzodithiadiazine led to Se-(2-aminophenyl)selenosulfate (Se-Bunte salt) or S-(2-aminophenyl)thiosulfate (Bunte salt), respectively.

A novel series of 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) inhibitors has been identified. These inhibitors, based on a dibenzazocine core, exhibited picomolar to low nanomolar inhibition of 17β-HSD3 in cell-free enzymatic as well as in cell-based transcriptional reporter assays.

A number of new pyrrolobenzothiazepine derivatives and a pyrrolobenzothiazocine derivative have been synthesized and evaluated for their affinity towards the 'peripheral-type' benzodiazepine receptor (PBR). The new compounds were tested in rat cortex, a tissue expressing a high density of mitochondrial PBR. Some of the pyrrolobenzothiazepines exhibited IC50 values in the low nanomolar range as measured by the displacement of [3H]PK 11195 binding. Compound 4i was found to be the most potent ligand for this receptor in the pyrrolobenzothiazepine subgroup with an IC50 practically identical to that determined for PK 11195. Structure-affinity relationships (SARs) have been developed to elucidate the topology of the PBR binding site.
