Research focus

My research is focused on the synthesis and development of cyclic lipodepsipeptide (CLiPs). These natural products, produced by Pseudomonas bacteria, are composed of a cyclic oligopeptide closed by an ester or ‘depsi’-bond and feature a fatty acid. Their biological properties are very diverse, making them the bacterial equivalent of a “Swiss Army Knife”. So far, interest has mainly focused on antimicrobial activity and antifungal activity. More recently, our attention has shifted to their promising anticancer potential. We are currently focusing on the fluorescent tagged CLiPs which would allow visualizing the peptide-cancer cell interaction using confocal microscopy.
