Development of new antimicrobial agents targeting Gram-positive bacterial sortase A



Project Title: „Development of new antimicrobial agents targeting Gram-positive bacterial sortase A” 

Funding: European Regional Development Fund (ERDF), Measure “Industry-Driven Research”

Project No.:

Period: 1st June 2017 – 31 st May 2020

Project costs: 583 689.55 EUR 

Principle Investigator: Dr. biol. A.Leončiks 


The aim of the project is to develop new antibacterial agents that target the enzyme sortase A found in most Gram-positive bacteria. Such agents with a new mode of action are urgently needed due to a notable increase of antibiotic-resistance among community- and hospital-acquired bacterial infections. Sortase A is a very attractive target for the development of new antibacterials because it plays a key role in bacterial virulence and infection by attaching important surface proteins to the cell wall, though not being essential for bacterial viability and thus reducing the possibility of developing resistance.

The aim of the project corresponds to the Latvian Smart Specialization Strategy in the field of development of human capital in science and technology and in creation of new knowledge in the following fields: biomedicine, medicinal technology, biopharmacy and biotechnology. The main and most basic part of the project that includes selection of the inhibitory compounds, structure and ligand interaction studies, and tests in animals will be carried out in the Biomedical Research and Study Centre where is the necessary infrastructure including equipment and competent scientific personnel. The additional studies of NMR structural analysis of inhibitors and all necessary chemical synthesis will be organized as outsourcing in a way as it was realized before in similar projects. It is possible to achieve the main goal of the project – discovery, selection and characterization of new antimicrobials against Gram+ pathogens Staphylococcus aureus, Listeria monocytogenes and Bacillus anthracis in a planned time frame of 36 months. By completing the project three scientific articles will be prepared and submitted.
