Researchers at Karolinska Institutet in Sweden have developed the first method for directly measuring the extent to which drugs reach their targets in the cell.
The method, which is described in the scientific journal Science, could make a significant contribution to the development of new, improved drug substances.
Most drugs operate by binding to one or more proteins and affecting their function, which creates two common bottlenecks in the development of drugs; identifying the right target proteins and designing drug molecules able to efficiently seek out and bind to them. No method has been available for directly measuring the efficiency of the drug molecules to locate and bind to its target protein. Now researchers from Karolinska Institutet have developed a new tool called CETSA (Cellular Thermal Shift Assay), which utilise the concept that target proteins usually get stabilised when drug molecules bind.
