Surfing the ground and excited state energy surfaces towards new applications in chemical biology

The behavior of molecules in the excited states can be dramatically different from the ground state, which can lead to a whole host of new reactivity. We seek to design molecules that can be controlled to exhibit different responses (i.e. bond cleaving reactions, emission of different colors of light) depending on the environment and conditions set by the user. These designs have applications in biomaterials and medical diagnostics. We are also developing methods to insert thioamide isosteres into previously uncharted peptide sequence space.

Molecular imaging with lanthanide complexes - from in vitro to in vivo

Many physiological processes are governed by small reactive species, anions and cations. As such, many pathologies are also marked by substantial deviations in the concentration and distribution of these species. Molecular probes have proven invaluable tools at deciphering the roles of biologically-relevant species, both in vitro and in vivo. Nonetheless, despite advances in molecular imaging, many small cations, anions and reactive species remain difficult to image selectively under conditions relevant to physiological processes.

Asymmetric Catalysis and its Application towards the Development of an Ideal Synthesis for BI’s 11β-HSD 1 Inhibitor

Abstract: During the past few decades, active pharmaceutical ingredients are becoming increasingly complex and costly to synthesize. Development of sustainable, greener and economically viable manufacturing processes is demanding. Asymmetric catalytic transformations with the aid of chiral phosphine ligands have played a critical part for API development.
