The reactions of benzodithiol-2-ones containing a 4-nitro group with NaHS led to mixtures of 6- aminobenzopentathiepines and 4-nitrobenzotrithiols. The product ratio and yields depend on the substituent in the aromatic ring. Based on the yields of benzopentathiepines, the following series of substituent efficiency can be inferred: CF3 F, Cl CN. Aminobenzopentathiepines are probably formed via the intermediate benzotrithiols; the transformation apparently starts with the reduction of the nitro group.
含有4- nitro基的苯二硫酮与NaHS反应,生成了6-氨基苯五硫啶和4-硝基苯三硫醇的混合物。产物的比例和产率取决于芳香环中的取代基。根据苯五硫啶的产率,可以推断出以下取代基效能的系列:CF3 > F > Cl > CN。氨基苯五硫啶可能是通过中间体苯三硫醇形成的;该转化显然是从硝基的还原开始的。

Striatal-enriched protein tyrosine phosphatase (STEP) is a brain specific protein tyrosine phosphatase that has been implicated in many neurodegenerative diseases, such as Alzheimer's disease. We recently reported the benzopentathiepin TC-2153 as a potent inhibitor of STEP in vitro, cells and animals. Herein, we report the synthesis and evaluation of TC-2153 analogs in order to define what structural features are important for inhibition and to identify positions tolerant of substitution for further study. The trifluoromethyl substitution is beneficial for inhibitor potency, and the amine is tolerant of acylation, and thus provides a convenient handle for introducing additional functionality such as reporter groups.

The cytotoxic and cancer preventive activities of synthetic analogs of natural varacins with polysulfide groups were studied. Presence of a sulfoxide group was found to have no significant effect on the cytotoxicity of these compounds. At the same time, this group is important for inhibition of colony formation of tumor cells treated with tumor promoter thus demonstrating cancer preventive activity. The most promising compound appears to be a synthetic varacin C analog, sulfoxide 10a, which exhibits the cancer preventive activity at dose into 100 times lower than its cytotoxic concentrations.

number of substituted benzopentathiepin-6-amines and their analogues without a polysulfur ring were synthesized and evaluated in vitro for antimicrobialactivity against a panel of reference bacterial and fungal strains. Trifluoroacetamide 14 demonstrated high antibacterial activity against Staphylococcus aureus (MRSA strain) with a MIC of 4 μg/mL, which was four-fold higher than the activity of a reference
