05/30/2005 A New Way To Fight Bacteria: Inhibitor blocks biosynthesis of key bacterial iron-scavenging agent (Chemical & Engineering News)

A novel strategy for fighting bacterial infections has been demonstrated: blocking bacterial biosynthesis of siderophores, compounds that make it possible for certain bacteria to obtain iron, which they require to grow and to cause disease. [Full text]
05/26/2005 Chemical Biology: Ironing out bugs (Nature)

Researchers from Cornell University and the Memorial Sloan Kettering Cancer Center in New York have devised a molecule that binds to and inhibits enzymes involved in siderophore synthesis. The compound successfully reduces the growth of both Mycobacterium tuberculosis and Yersinia pestis under iron-poor in vitro conditions. [Full text]
01/04/2005 NIH Initiatives Target Chemistry: New road-map-related initiatives show agency values role of chemistry in biomedical research (Chemical & Engineering News)

Graduate student Shiying Shang and postdoctoral fellow Jae-Sang Ryu work on developing diversity-oriented syntheses of libraries in the lab of Tan—work that fits nicely into a new road-map-related initiative. [Full text (membership req’d) | Full text (PDF)]
03/15/2004 Pin the Tail on the Olefin: Researchers seek practical methods for adding terminal functional groups to alkenes (Chemical & Engineering News)

Chemists have been trying for some time to find a practical synthetic method that the chemical industry could use to add terminal functional groups such as alcohols, ethers, and amines to olefins. Several research teams have now progressed toward that goal by developing anti-Markovnikov reactions that add such functional groups to alkene double bonds. [Full text (membership req’d)]
