Combating bacterial resistance: optimisation of bacterial cell wall biosynthesis inhibitors (L1-6745, 1.7.2014-30.6.2017)

Principal Investigator: prof. dr. Stanislav Gobec

Infections caused by antibiotic-resistant bacteria continue to challenge health-care systems worldwide. We face growing resistance of Gram-positive and Gram-negative pathogens that cause infections in hospitals and in the community, with the so-called antibiotic-resistant ‘superbugs’ that now represent a major global health problem. It has been reported that 25,000 Europeans die each year as a direct consequence of infections with multidrug resistant strains of pathogenic bacteria, with an estimated economic impact of 1.5 billion Euro per year. However, the pipeline for new drugs is small, because the major pharmaceutical companies have largely abandoned antibiotic discovery even though new drugs are urgently needed. The obstacles of having few new antimicrobials on the horizon and facing increasing frequency of multidrug resistance mean that we must redouble our efforts in the search for new antimicrobials. It is imperative that we continue to search for new antibacterial drugs through innovative screening methods, and undertake rational drug design using the advances provided by protein crystal structures.

Peptidoglycan is a macromolecule that is essential for and specific to the bacterial cell wall. The enzymes involved in its biosynthetic pathway constitute potential targets for the discovery of new antibiotics. During the past 15 years, the group of PI Gobec has developed a number of important peptidoglycan biosynthesis inhibitors, the most important of which are inhibitors of the Mur enzymes (MurA to MurF) and DdlB, and of penicillin-binding proteins. In this Project, we will push forward the development of these inhibitors and optimise their on-target activities, and physico-chemical and pharmacokinetic properties.

Our approach to optimisation of inhibitors will combine the extensive knowledge within our team and our international collaborators of target enzymes and their inhibition, with cutting edge drug discovery and medicinal chemistry techniques. The Project will also benefit from detailed structural analyses, which will enable rapid in-silico design of improved inhibitor scaffolds, and subsequently, identification of novel and potent inhibitors with antibacterial activity. The optimisation of inhibitors is based on an iterative approach including computational design, and synthesis of libraries of inhibitor analogues, followed by biochemical, structural, microbiological, preliminary pharmacokinetic and toxicological evaluation. We expect to develop at least two optimised lead compounds or clinical candidates with potential to be taken forward in collaboration with the pharmaceutical industry, or to form the basis for creation of a Start-up Company. These are very important steps towards development of new broad-action antibacterials that will be of key importance in the fight against bacterial resistance. It is thus the intention of this Project to fill the gap between the burden of infections due to multidrug-resistant bacteria and the decreasing level of new antibiotics in development.

Theoretical and practical Aspects of Terminology and Terminography in Connection with Internet Terminological Resources (L6-4045, 1.7.2011 - 30.06.2014)

The research project involves theoretic and applicative work: researching and developing terminological and terminographical theory (terminological definitions, individual parts-of-speech in terminology, e.g. the verb in legal terminology, antonymy, researching the influence of English on Slovenian with an emphasis on terminology, Slovenianisation of terminology), publication of results in monographs, articles, lectures, creating new and updating existing computer tools for processing terminology (SlovarRed 2.1), creating and publishing specialised corpora, processing, translating and standardising the terminologies of various fields, compiling and publishing normative explanatory mono- and multilingual dictionaries in paper and electronic form (the internet), organising Slovenian and international professional meetings, conducting terminological counceling. We also intend to cooperate with the Slovenians living abroad and important European terminological centres.

Preclinical development of new antibacterial drugs (L1-4039,1.7.2011 - 30.06.2014)

Principal Investigator:  prof. dr. Stanislav Gobec

As society has become increasingly dependent upon antibiotics, the selection pressure for emergence of resistant bacterial strains has increased, and so-called antibiotic-resistant ‘superbugs’ are now a major global health problem. The development of resistance can interfere with, or even prevent, the treatment of bacterial infections, especially in hospitals. New drugs are urgently needed to provide doctors with fresh options to treat these infections. We intend to discover new inhibitors which will attack the formation of bacterial peptidoglycan, and this will either kill the bacteria directly or make them more susceptible to existing antibiotics.
Peptidoglycan is a macromolecule which is essential for and specific to the bacterial cell wall. The numerous enzymes involved in its biosynthetic pathway constitute potential targets for the discovery of new antibiotics. To identify novel lead compounds that are important for antibacterial drug discovery, we will target the selected enzymes that catalyze the intracellular stages (Mur ligases MurC-F and DdlB) and extracellular stages (the penicillin-binding proteins) of peptidoglycan biosynthesis. Strategies for inhibitor discovery will be based on the available X-ray crystal structures and will involve sophisticated computational techniques, like de novo structure-based inhibitor design and virtual high-throughput screening, and chemical synthesis of libraries of potential inhibitors and their biochemical (evaluation of inhibitory activities), structural (determination of X-ray crystal structures) and antimicrobial (determination of MIC values) evaluation. It is intended to discover several structurally distinct lead molecules with micromolar or nanomolar inhibition of target enzymes and with antimicrobial activities.
The strength of this project includes (1) the multi-targeted approach that involves enzymes from a variety of pathogenic species, and (2) the vast number of techniques employed, provided by the different types of highly complementary expertise of all partners incuded. The group of the partners from Slovenia is specialised in computational drug discovery methods like virtual high-throughput screening and de novo molecular design, medicinal chemistry and synthetic organic chemistry, while other international partner groups are specialised in bacterial peptidoglycan biosynthesis enzymes expression and purification, biochemistry, microbiology and X-ray crystallography. During the previous collaboration with international partners and Slovene pharmaceutical company Lek d.d. we have developed a series of promising inhibitors of bacterial peptidoglycan biosynthesis enzymes and this work will be countinued during this project. Lead compounds identified in this project will represent very important steps towards the development of new broad action antibacterials that will be of key importance in the fight against emerging bacterial resistance.

INTEGRATE - Interdisciplinary Training Network for Validation of Gram-Negative Antibacterial Targets (H2020 MSCA ITN)

Duration of the project: 2015 – 2018
Slovenian PI: prof. dr.Danijel Kikelj

Antimicrobial resistance is posing a continuously-rising threat to global health. Indeed, one key recommendation from the recent “Action plan against the rising threats from Antimicrobial Resistance” report (submitted by the Commission to the European Parliament and Council (15.11.2011)) is the development of effective antimicrobials or alternatives for treatment of human and animal infections. The INTEGRATE project is a direct response to this. We have assembled a team of ten beneficiaries from eight EU member states, encompassing both academic and nonacademic sectors and different disciplines, to form a consortium committed to training Early Stage Researchers (ESRs) in the discovery and preclinical validation of novel Gram-negative antibacterial agents and antibacterial targets. The principle aim of the consortium is to provide a training platform where students are exposed to every aspect of the antimicrobial discovery process, ranging from target identification and validation, through organic synthesis, in silico design and compound screening, to mode-of-action and possible resistance mechanisms. This exposure will be accomplished through a concrete secondment plan, coupled with a series of high-level consortiumwide training events and networking programmes. Our intention is to reverse the current fragmentation of approaches towards antibacterial discovery through mutual cooperation. The INTEGRATE training framework is built on an innovative research project aimed at targeting important but non-essential gene products as an effective means of reducing bacterial fitness, thereby facilitating clearance of the pathogen by the host immune system. To achieve this, the individual work programmes have been designed to seamlessly inter-mesh contributions from the fields of in silico design, organic synthesis, molecular biology and biochemistry, and the very latest in vitro and in vivo screening technologies.

An ambitious four-year project to discover and develop potential new medicines against multiple drug resistance tuberculosis (TB) has been launched by an international consortium of 12 diverse groups.

The ORCHID alliance (Open Collaborative Model for Tuberculosis Lead Optimization) brings together TB expertise from academia, government research centres, non-for-profit organizations and small biotechnology companies with funding from the EU’s Seventh Framework Programme for Research (FP7). Under the leadership of the pharmaceutical company GlaxoSmithKline, more than 25 scientists worldwide will pool their expertise to investigate the potential of three different areas of research, all of which have shown potential activity against TB.

The aim is to complete drug discovery research to have identified and validated a novel candidate molecule ready to be tested in humans. It is only through the collaboration of such diverse experts group that all three areas can be progressed in a coordinated fashion.

The three areas to be investigated are:

  • β-lactams  new evidence suggests a novel approach could make these broad spectrum antibioitics effective against TB. This approach will seek to design new animal models to demonstrate the potential of B-lactams as treatments against TB.
  • New InhA inhibitors – GSK in collaboration with TB Alliance have recently identified a chemical series that can inhibit recognised known TB target (InhA), which is essential for the bacterium’s survival. Tool compounds in this series have shown activity against multi drug resistant strains (MDR-TB) in the lab and have also demonstrated promising activity in animal models of Mycobacterium tuberculosis.
  • Whole-cell hits – Compounds that have been shown to be active against TB in high through put screening, but their mode of action is unknown. The project will aim to understand this activity.

Biodiversity in the seas is only partly explored, although marine organisms are excellent sources for many industrial products. Through close co-operation between industrial and academic partners, the MAREX project will collect, isolate and classify marine organisms, such as micro- and macroalgae, cyanobacteria, sea anemones, tunicates and fish from the Atlantic, Pacific and Indian Oceans as well as from the Mediterranean, Baltic and Arabian Seas. Extracts and purified compounds of these organisms will be studied for several therapeutically and industrially significant biological activities, including anticancer, anti-inflammatory, antiviral and anticoagulant activities by applying a wide variety of screening tools, as well as for ion channel/receptor modulation and plant growth regulation. Chromatographic isolation of bioactive compounds will be followed by structural determination. Sustainable cultivation methods for promising organisms, and biotechnological processes for selected compounds will be developed, as well as biosensors for monitoring the target compounds. The work will entail sustainable organic synthesis of selected active compounds and new derivatives, and development of selected hits to lead compounds.

The project will expand marine compound libraries. MAREX innovations will be targeted for industrial product development in order to improve the growth and productivity of European marine biotechnology. MAREX aims at a better understanding of environmentally conscious sourcing of marine biotechnology products and increased public awareness of marine biodiversity and potential. Finally, MAREX is expected to offer novel marine-based lead compounds for European industries and strengthen their product portfolios related to pharmaceutical, nutraceutical, cosmetic, agrochemical, food processing, material and biosensor applications.

The introduction of antibiotics in the medical practice has drastically reduced illness and death from infectious diseases. However, bacteria have exhibited a remarkable capacity to become resistant to commonly used antibacterial compounds. In parallel to efforts aimed at better understanding the strikingly diverse mechanisms they use, it is important to design strategies which will allow to counteract them and to search for new targets, ideally essential and specific to bacterial physiology.

The approach followed in EUR-INTAFAR is based on the well established facts that peptidoglycan biosynthesis and cell morphogenesis are related phenomena and that they are totally specific to bacterial cells, without even remotely equivalent processes in eukaryotic cells.
By attempting to interfere with these processes by inhibiting enzyme activities or perturbing protein-protein interactions, one should be able to design new antibacterial compounds active against pathogenic organisms such as streptococci, staphylococci, enterococci or chlamydiae.
