Our research is directed at characterizing structures and biological functions of biogenic small molecules (BSM’s). BSM’s play important roles in most biological processes, and detailed knowledge of their chemical structures and their interactions with other biomolecules is essential for advancing our molecular understanding of life. BSM’s regulate development and immune responses in plants and animals, and serve important functions in interactions of different organisms with each other. As a result, an organism’s metabolome essentially comprises a collection of small molecules with potentially useful affinities for specific molecular targets. Not surprisingly, BSM’s constitute the most important source of lead structures for drug development.
Compared to template-derived biological macromolecules such as proteins and nucleic acids, BSM’s are chemically much more diverse and correspondingly present great analytical challenges. As a result, genomic and proteomic knowledge has not yet been complemented by a comprehensive characterization of structures and functions of metabolomes, presenting one of the most significant barriers toward advancing our understanding of biological pathways.
The Schroeder lab aims to help close this knowledge gap by developing approaches for a more systematic structural and functional characterization of BSM’s. Usually, BSM’s occur as – often minor – components of a more or less complex biological matrix, comprising a large number of BSM’s and other biomolecules. Traditional approaches for the characterization of BSM’s such as HPLC-MS or activity-guided fractionation have distinct disadvantages that severely limit their applicability. Our aims is to develop NMR spectroscopy-based approaches that complement or enhance traditional methodology by enabling detailed characterization of BSM’s in complex biological samples, with regard to both chemical structure and biological function.
Based on NMR-spectroscopic methodology we have engaged in a comprehensive effort to characterize structures and functions of the metabolome (the entirety of all BSM’s) produced by the model organism Caenorhabditis elegans, focusing on several newly discovered compounds that control development, and ultimately lifespan. In addition we have started a project directed at investigating the chemical ecology of microorganisms in search of leads for new antibiotics. Complementing our interests in analytical chemistry, we pursue development of efficient syntheses for newly identified compounds with particular biological significance.

- People have used aspirin to treat pain, fever and inflammation for more than a century, and the drug is also used to reduce the risk of strokes, heart attacks and some cancers. An estimated 100 billion aspirin tablets are taken worldwide each year, but how it works is still only partially understood. Dan Klessig, a […] Read more »
- We would like to congratulate a pair of BTI faculty members who recently published high-impact research papers in the prestigious research journal Nature. Frank Schroeder and colleagues discovered the first clues on how gut health influences brain health. Published on October 23, the researchers describe new cellular and molecular processes underlying communication between gut microbes […] Read more »
- Every day, people are exposed to myriad chemicals, both natural and synthetic. Some of these compounds may affect human physical development, but testing them directly on people would be grossly unethical. To get around this dilemma, researchers from Boyce Thompson Institute used Caenorhabditis elegans, a soil roundworm, to show that tiny amounts of natural compounds […] Read more »
- Protecting crops from pests and pathogens without using toxic pesticides has been a longtime goal of farmers. Researchers at Boyce Thompson Institute have found that compounds from an unlikely source – microscopic soil roundworms – could achieve this aim. As described in research published in the May 2019 issue of Journal of Phytopathology, these compounds […] Read more »
