Presentation of the department
The department of Chemical Biology is naturally positioned at the interface between synthetic Chemistry and Biology. The department’s staff combines expertise in highly complementary disciplines such as organic (glycochemistry, peptide chemistry, molecular probes) and inorganic synthesis (organometallic lanthanides or transition metals complexes), in cellulo or in vitro chemistry, biochemistry and molecular biology, enzymology. This diversity of talents is federated around a common interest for the investigation of biological events, the design and elaboration of new tools and strategies for their study, their understanding, and potentially their regulation. Chemistry is principally concentrated on the search for properties or function, although this is not exclusive of the development of new, original methods or synthetic strategies, and the search for reactivity. Biology is mainly focusing on redox signaling in mammalian cells with a strong interest in nitrogen monoxide (NO) and hydrogen peroxide, two chemical messengers capable of triggering biological response, and two of their target proteins, including Fe-S proteins. The biological targets are selected according to their academic and/or societal interest, and find applications in various domains such as microbiology, agronomy or human health. Research conducted in the department can also find inspiration in the observation of biological processes, to construct new molecular objects with an interest for health and sustainable development. The department of Chemical Biology is organized around two thematic groups, entitled « Probes and modulators for biological targets » and « Oxidative stress, Iron-Sulfur proteins ans cancer », and a screening platform named « CiBi – Cibles Biologiques », focusing on the biological evaluation of small molecules
