Thiocarbamoylation of hydrazones of aromatic aldehydes with tetramethylthiuram disulfide (TMTD) afforded diarylaldazines, 4,4-dimethylthiosemicarbazide, and 5-dimethylamino-1,3,4-thiadiazole-2-thiol. In addition, the reaction of TMTD with salicylaldehyde hydrazone yielded symmetrical thiocarbonyldihydrazone of salicylaldehyde, whereas the reactions with p-bromobenzaldehyde and m-nitrobenzaldehyde hydrazones afforded p-bromo- N, N-dimethyl- and N,N-dimethyl-m-nitrothiobenzamides, respectively. Possible pathways of formation of the resulting products are discussed.

therapies for metabolic and cardiovascular diseases. A series of novel adamantylheterocyclicketones provides potent and selective inhibitors of human 11β‐HSD1. Lead compounds display low nanomolar inhibition against human and mouse 11β‐HSD1 and are selective with no activity against 11β‐HSD2 and 17β‐HSD1. Selected potent 11β‐HSD1 inhibitors show moderate metabolic stability upon incubation with human liver
