Synthetically-derived S,S-heterodisubstituted disulfides that exhibit potent in vitro antibacterial activity against a variety of bacteria, including Staphylococcus aureus, methicillin-resistant Staphylococcus aureus and Francisella tularensis. The present invention provides compounds, methods and compositions effective to treat microbial/bacterial infections, and, especially, infections arising from bacteria which have developed resistance to conventional antibiotics.

The central focus of this study is on the antibacterial and antifungal properties of synthetically produced S,S'-bis(heterosubstituted) disulfides as a means to control the growth of various infection-causing pathogens. Staphylococcus aureus, Francisella tularensis and Candida albicans were each found to be highly susceptible to several of these compounds by agar or broth dilution and Kirby-Bauer diffusion assays. These structurally simple, low molecular weight disulfides have shown promising bioactivities and may serve as leads to the development of effective new antibacterials for pathogenic bacteria such as methicillinresistant S. aureus and F. tularensis.

By the reaction with three N,N-dialkylanidosulfenyl chlorides 2 bearing representative sizes for the R group on the nitrogen atom, several substituted secondary propargylic alcohols (la-f) have been converted into the corresponding pairs of diastereoisomeric allenic sulfinamides 3a-n and 3′a-j,l.m. Their ratios have been determined by 1H NMR spectroscopy and were found to depend essentially on the
通过与在氮原子上的R基团具有代表性尺寸的三个N,N-二烷基氨基亚磺酰氯2反应,已将几种取代的仲炔丙醇(Ia-f)转化为相应的非对映异构烯丙亚磺酰胺3a-n和3 'aj,lm。它们的比率已经通过1 H NMR光谱法确定,并且发现其比率基本上取决于起始材料的R 1和R 2基团的大小。一种纯非对映异构体3m的立体化学已通过单晶X射线分析确定。
