Project title:
Conjugates of aminoglycosides with amphipathic peptides as antibacterials
Competition type: SONATA 15
Financing institution: National Science Centre (Narodowe Centrum Nauki)

Project description:
The aim of this project is to design and synthesize conjugates of aminoglycoside antibiotics with peptides, as well as determination of their antimicrobial activity. Positively charged antibiotics, such as aminoglycosides, do not easily pass through bacterial membranes. In order to enhance their transport through the bacterial membrane, they
will be combined with peptide-like carriers. Conjugation of aminoglycoside antibiotics with peptides that penetrate the bacterial membrane should increase their antibacterial activity. We will also use the stapling technique to stabilize the helical structure of the designed peptides and, in consequence, to improve effectiveness of their penetration through bacterial membranes. This should also improve the effectiveness of aminoglycoside transport to bacterial cells, and as a result their antibacterial activities.

Key responsibilities include:

– syntheses and purifications of peptides and their conjugates with aminoglycosides.
– studies of the interactions of peptide-aminoglycoside conjugates with bacterial membranes.
– performing bacterial growth inhibition and resistance assays.
– performing and analyzing experiments, writing reports, presenting the results at seminars and conferences.

Profile of candidates/requirements:
– MSc degree in biology, biotechnology, (bio)chemistry, (bio)physics or related field. The MSc degree should be obtained before the date of employment in the project – by 30.09.2020 at the latest;
– Confirmed status of a PhD student on the day of starting the work in the project (01.10.2020).
