  Discovery of LFF571: An Investigational Agent for Clostridium difficile Infection

  摘要：

  Clostridium difficile (C. difficile) is a Gram positive, anaerobic bacterium that infects the lumen of the large intestine and produces toxins. This results in a range of syndromes from mild diarrhea to severe toxic megacolon and death. Alarmingly, the prevalence and severity of C. difficile infection are increasing; thus, associated morbidity and mortality rates are rising. 4-Aminothiazolyl analogues of the antibiotic natural product GE2270 A (1) were designed, synthesized, and optimized for the treatment of C. difficile infection. The medicinal chemistry effort focused on enhancing aqueous solubility relative to that of the natural product and previous development candidates (2, 3) and improving antibacterial activity. Structure-activity relationships, cocrystallographic interactions, pharmacokinetics, and efficacy in animal models of infection were characterized. These studies identified a series of dicarboxylic acid derivatives, which enhanced solubility/efficacy profile by several orders of magnitude compared to previously studied compounds and led to the selection of LFF571 (4) as an investigational new drug for treating C. difficile infection.

• Ni-catalyzed two-component reductive dicarbofunctionalization of alkenes <i>via</i> radical cyclization
  作者：Yulong Kuang、Xuefeng Wang、David Anthony、Tianning Diao

  DOI：10.1039/c8cc00358k

  日期：——

  A reductive dicarbofunctionalization reaction of alkenes has been developed and applied to the preparation of substituted carbo- and heterocycles. The reaction conditions avoid the use of air-sensitive organometallic reagents, and are compatible with a broad range of bromo-electrophiles and a wide variety of substituents to give cyclic products in excellent yields.

  已经开发了烯烃的还原性双碳官能化反应，并将其用于制备取代的碳环和杂环。反应条件避免了使用对空气敏感的有机金属试剂，并且可与各种溴亲电子试剂和各种取代基兼容，从而以优异的收率得到环状产物。
