Henrik Franzyk

Associate Professor

Henrik Franzyk (HF) has for more than 10 years designed and synthesized biologically active peptides and peptidomimetics as well as glycolipids and cationic lipids (used as components for drug delivery and nanoparticles). In addition, HF has performed optimization of several lead structures via medicinal chemistry.

National collaborators comprise:

Lone Gram (Prof. Systems Biology, DTU); Peter M. H. Heegaard (Prof. Immunology, DTU-VET); Anders Løbner-Olesen (Prof. Biology, KU); Peter E. Nielsen, Prof. Dept. Cellular and Molecular Biology, KU); Peter P. Damborg (Assoc. Prof., IVS, KU); Statens Serum Institut (several senior scientists); Dept. Pharmacy (Prof. Hanne M. Nielsen and Assoc. Prof. Camilla Foged; KU)

International collaborators comprise:

Claes Dahlgren, Sahlgrenska Academy, University of Gothenburg, Sweden; R. E. W. Hancock, University of British Columbia, Vancouver, Canada; Luca Guardabassi, Ross University School of Veterinary Medicine, St. Kitts; Ian Mellor, University of Nottingham.

Current projects are supported by University of Copenhagen and EU (IMI project: ENABLE). The scientific outcome during 2012-2016 comprise identification and characterization of:

(i) Potent antibacterial peptidomimetics with activity against multidrug-resistant (MDR) bacteria and biofilm;

(ii) Antimicrobial activity of AMP-PNA conjugates (i.e. antimicrobial peptides covalently linked to peptide nucleic acid oligomers);

(iii) Immunomodulatory peptidomimetics capable of LPS- and LTA-neutralization as well as with nanomolar agonistic and antagonistic selective effects on formyl peptide receptor 2 (FPR2); 

(iv) Components for liposomal and nanoparticular drug formulations, e.g. of siRNA aiming at silencing of genes (or the resulting mRNA) involved in chronic diseases. 

During 2012-2016 these studies have been published in 41 articles in peer-reviewed journals. Currently, HF has published a total of 109 peer-reviewed articles and monographies, 2 book chapters, and 55 other research contributions (e.g. communications/presentations/posters);
