Proteins control almost all vital processes in our cells. If they do not function correctly, if there is too much or too little of them, this can lead to the development of a variety of diseases including cancer. The associated proteins are therefore also important targets for drug discovery in biomedical research.
However, lamictal patent expiration there are large number of proteins that simply do not offer suitable targets for a conventional active ingredient to dock onto. That’s why scientists in UDE’s Collaborative Research Center 1093 are developing small, unusual molecules called supramolecular ligands that can precisely bind to their surface.
Molecules block pivotal site of the protein
Recently, the team of scientists led by Prof. Shirley Knauer, Prof. Elsa-Sanchez-Garcia and Prof. Thomas Schrader succeeded in targeting a critical interface that is important for the survival of cancer cells with such customized molecules. “The protein survivin is actually hardly found in healthy adult organisms,” so Prof. Shirley Knauer. “In cancer cells, however, its production is ramped up.” Using an artificial, tailored ligand, the scientists were able to cover the exact site of the survivin, which is responsible for its activation and transport out of the cell nucleus.
