Chemical Biology elucidates the course and the modulation of molecular biological processes, including the interactions and functions of proteins, oligonucleotides, oligosaccharides, and secondary metabolites, by employing the power of chemical concepts and molecular probes. Chemical Biology research adopts state-of-the art methods such as computer-aided design, compound collections, molecular probing techniques, structural biology as well as latest analytical and screening technologies to identify new biologically active compounds or activity principles.
