/ Introduction
/ Project aim and strategies
The emergence and spread of antimicrobial
resistance in common human pathogenic
bacteria, as well as the increased awareness
of biofilm production in the pathogenesis of
human bacterial infections has fuelled the
need for new antimicrobial compounds and
new antibacterial strategies1. There is also a
critical need for novel therapeutics for pain
management.
Natural products play an invaluable role in
the drug discovery process and the majority
of drugs currently in commercial use in addition to those being developed, are of natural
origin.
The wide repertoire of biological functions
covered by natural peptides makes them an
interesting target for bioprospecting and
drug discovery 2, 3.
