Wake-promoting agents: Search for next generation modafinil: Part I
摘要:
In search of a next generation molecule to the novel wake promoting agent modafinil, a series of bi-phenyl derived wakefulness enhancing agents (in rat) was developed. From this work, compound 17 has been selected for additional studies. (C) 2011 Elsevier Ltd. All rights reserved.

efficient catalytic method for the preparation of S‐aryl isothiouronium salts, and demonstrate that these air‐stable, odorless solids serve as user‐friendly sources of thiophenols in synthesis. Diverse isothiouronium salts featuring synthetically useful functionality are readily accessible by nickel‐catalyzed C−S cross‐coupling of (hetero)aryliodides and thiourea. Convenient, chromatography‐free isolation
The identification of MreB as essential for bacterial chromosome segregation provides a new target for antibiotic action. The MreB function is useful in the development of screening assays for new antibiotics, which may use, for example, genetic mutants in MreB, tests of MreB mediated chromosome segregation, and the like. In one embodiment of the invention, the antibiotic is an isothiourea compound, which may comprise a polyhalogenated benzyl group, e.g. at the 4 position, the 2,4 position, etc. A pharmaceutical composition comprising an MreB targeted antibiotic as an active agent is administered to a patient suffering from a microbial infection, particularly bacterial infections.
Structure-Activity Relationship Study of the Bacterial Actin-Like Protein MreB Inhibitors: Effects of Substitution of Benzyl Group in<i>S</i>-Benzylisothiourea
We comprehensively investigated the effects of substitution of the benzyl group in S-benzylisothiourea derivatives on antibacterial activity, because we found previously that some substitutions enhanced it. A 2,4-Cl2-derivative was found to be the most effective compound, it was stronger than the original one in Gram-negative rod shaped-bacteria such as Escherichia coli and Salmonella typhimurium.
