Synthesis and antimicrobial activities of structurally novel S,S′-bis(heterosubstituted) disulfides
摘要:
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.

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.

Methods, devices, systems, and materials are disclosed for diffraction unlimited photofabrication. A method is provided where a photoresponsive material is illuminated with a first optical pattern at a first wavelength of light. The first wavelength of light alters a solubility of the photoresponsive organic material. The photoresponsive material is also illuminated with a second optical pattern at a second wavelength of light. The second wavelength of light hinders the ability of the first wavelength of light to alter the solubility of the photoresponsive organic material where the second optical pattern overlaps the first optical pattern. The photoresponsive organic material is then developed.
