Sugar molecule with docking station
No wonder, therefore, that galectin-1 has become a major focus of research. Seibel and his colleague Dr. Clemens Grimm is interested in a very specific section of this protein, the so-called carbohydrate recognition domain. They have now designed a complex sugar molecule that fits perfectly into this domain, as the scientists report in journal "ChemBioChem". "We have equipped the sugar molecule with a docking site, for example, to connect it with a fluorescent dye or an drug," says Seibel. In addition, the scientists have described the binding of their molecule to galectin-1 with high-resolution X-ray structure analyzes.
"Our findings can serve the development of high-affinity ligands of the protein Galectin-1 and thus of new drugs," said Clemens Grimm.
Quick test for Galectin-1 in progress
Now the JMU scientists are working on a rapid test for the detection of galectin-1. It is designed to enable early detection of tumors such as neuroblastoma. For the future, Seibel's team would like to expand the sugar molecules into a kind of shuttle system that allows pharmaceutical agents to be transported directly to the tumors.
