Abstract
3-Aryloxy- and 3-phenylsulfanylthietane-1,1-dioxides were synthesized by reacting 3,5-dibromo-1-(1,1-dioxothietan-3-yl)-1,2,4-triazole with sodium phenolates and thiophenolate. The 5-aryloxy- and 5-arenesulfonyl-3-bromo-1-(1,1-dioxothietan-3-yl)-1,2,4-triazoles were synthesized via oxidation by H2O2 of 5-aryloxy- and 5-phenylsulfanyl-3-bromo-1,2,4-triazoles containing thietane or thietane oxide rings. The 3-substituted thietane-1,1-dioxide IId (2 and 20 mg/kg) displayed antidepressant properties in tail-suspension (TST) and forced-swim tests (FST) that were comparable with those of imipramine. Low toxicity risks (mutagenicity, tumorigenicity, irritation, reproductive toxicity) and satisfactory pharmacokinetic characteristics (correspondence to Lipinski’s rule of five) were predicted (Osiris Property Explorer, Molinspiration) for it.
