Creating a Synthetic Platform for Understanding and Exploiting Glycoconjugates
Lead Research Organisation:
University of Oxford
Department Name: Oxford Chemistry
Abstract
The evidence for the importance of carbohydrates in biology is increasing exponentially. Unlike other biomolecules (lipids, proteins, nucleosides) significant expertise is needed in the construction of corresponding glycoconjugate probes used to understand and exploit this biology: for example, no automated oligosaccharide synthesizer to date exists for the construction of all the glycoside linkages. The possible permutations for something as simple as the hexasaccharide structures stretch to greater than 1.05 x 1012 possible combinations. This level of complexity highlights that synthesis of glycoconjugates must be guided by functional design, and cannot simply be achieved through random synthesis of all possible combinations. There are a number of startling and challenging high-risk problems that exist in the field of glycoscience that the Platform would allow us to tackle. The risk is high, the challenges of complexity great (due, in part, to the typical lack of direct genetic control of glycoconjugate synthesis within biology) but the potential rewards are tremendous.

Sugar solutions - Interview
in MOLECULAR BIOSYSTEMS
Description | This Platform grant allowed us scientific freedom to explore some highly unconventional ideas for how molecules containing sugars (so-called glycoconjugates) might work in nature and might be used in medicine. From this work we have discovered new sugar-based drugs to treat disease (including new classes of antibiotics), new ways of detecting disease at a much earlier stage (e.g. TB or MS) and new ways of understanding how nature handles and builds sugars. |
Exploitation Route | The fundamental discoveries are allowing those interested in applications, such as diagnosing or treating disease to do this based on a better understanding. We too are developing these techniques, in partnership with leading clinicians. |
