Click Chemistry in Biology and Medicine

Click Chemistry in Biology and Medicine
Reported by
Megan Stephan

Posted November 21, 2014


Click chemistry is a new approach to synthetic organic chemistry that uses simple chemical building blocks and mild aqueous conditions to produce high-specificity ligands and labeling molecules for the investigation of biological systems. These reactions mimic those found in nature for building large complex molecules such as proteins, DNA, and RNA. Since its inception by K. Barry Sharpless, click chemistry has yielded several novel reactions that have been used to produce experimental tools and therapeutic agents, some of which are now in preclinical testing. The products of these reactions are particularly useful for investigating difficult-to-synthesize biological products such as glycans, and challenging, highly transient signaling activities such as those depending on redox reactions. On September 15, 2014, pioneers and young investigators in the field presented their recent work, providing a glimpse into the expanding possibilities of this synthetic methodology. The symposium, Click Chemistry in Biology and Medicine: New Developments and Strategies, was presented by the Academy's Chemical Biology Discussion Group.
