Drug Design and Optimisation

Prof Dr Anna K. H. Hirsch

The Hirsch group adopts a target-based rational design strategy focusing on biologically relevant, often underexplored enzymes, transporters and regulators within bacterial and parasitic pathogens. The group employs a variety of biophysical methods to investigate compound–target interactions and has established several in vitro and cell-based assays for straightforward evaluation of novel anti-infectives and multiparameter optimisation.

Our research and approach

The emergence of drug-resistant strains of human pathogens such as P. aeruginosa, S. aureus or S. pneumoniae is a recognised threat to human health and urgently calls for the development of new antibacterial agents with novel modes of action. The department adopts a target-based strategy focussing on a portfolio of two types of drug targets.

The first group comprises targets which impair vital mechanisms within the bacteria and effectively kill them. One example is the enzyme DXS which plays a crucial role in the methylerythritol phosphate pathway, which is essential for the biosynthesis of universal isoprenoid precursors in many gram-negative pathogens, but absent from humans. The second group comprises targets interfering with pathogenicity and virulence without affecting bacterial viability. These pathoblockers are believed to cause a lower rate of resistance development, whilst leaving the commensal microbiota untouched.

The Hirsch group applies a series of established hit-identification strategies, including structure- and fragment-based drug design, classical medicinal chemistry and virtual screening. In addition, pioneering of innovative protein-templated methods such as dynamic combinatorial chemistry and kinetic target-guided synthesis in terms of the scope of chemical reactions, biological targets and synergistic combinations addresses key bottlenecks. Use of established and innovative techniques to design, synthesize and profile the most promising inhibitors enables efficient subsequent multiparameter optimisation as well as elucidation of the mode of action.

Scientists in the interdisciplinary team have diverse backgrounds such as medicinal chemistry, synthetic organic chemistry, pharmacy, pharmacology, biology or biochemistry, resulting in a diverse skill set.

Research projects

Due to the rapidly increasing number of pathogenic bacteria being resistant to common antibiotics, the development of new antibacterial agents is urgently needed. To address these problems, the Hirsch group adopts a strategy based on the rational design and synthesis of anti-infectives with novel modes of action. In this context, the group is focusing on a portfolio of biologically relevant, ideally underexplored enzymes, transporters and regulators within bacterial pathogens. These drug targets can be grouped into those that impair vital mechanisms within the bacterium and effectively kill them (e.g., ECF-T, DnaN and DXS) and those that interfere with the pathogenicity and virulence without affecting bacterial viability (e.g., ColH and LasB). 

The group employs a variety of biophysical methods to identify novel hit compounds and to investigate compound–target interactions. Various in vitro and cell-based assays, the generation of in silico data and the co-crystallization of selected compounds with their targets support the straightforward evaluation of novel anti-infectives and their further optimisation by classical and innovative medicinal chemistry approaches.

Below you will find an overview of selected targets we are currently addressing and to which we apply the above-mentioned strategies:

ECF-T

The energy-coupling factor (ECF) transporters are a family of transmembrane proteins involved in the uptake of vitamins by a wide range of bacteria. Inhibition of the activity of these proteins could reduce the viability of organisms that depend on vitamin uptake, including pathogenic species such as Staphylococcus aureus, Streptococcus pneumoniae and Enterococcus faecium. As these bacteria cannot synthesize important vitamins such as folic acid, pantothenate and niacin de novo, they depend on ECF transporters to take them up from the environment. Due to this central role in the metabolism of bacteria, ECF transporters are novel potential antimicrobial targets to tackle infection. Recently we identified the first classes of selective antibacterial agents showing promising inhibition of the ECF transporters. We are currently trying to further develop these compounds.

MEP pathway (target: DXS, IspD, IspE):

The methyl erythritol phosphate (MEP) pathway is a rich, underexplored source of anti-infective targets that are absent from humans but essential in many pathogenic bacteria, protozoa and plants. This opens up the possibility of developing highly selective inhibitors that are active against clinically relevant pathogens such as four ESKAPE pathogens: Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter spp., all of which have highest priority according to the WHO Global Priority List of antibiotic-resistant bacteria – as well as Mycobacterium tuberculosis and Plasmodium falciparum. In these pathogens, the MEP pathway is the sole source of isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP). The latter are the universal building blocks for the biosynthesis of isoprenoids, a large and diverse class of natural products fulfilling a myriad of indispensable functions. With DXS, IspD, IspE we address three essential enzymes of this pathway. Our best compounds are highly active against the mentioned pathogens and show nanomolar IC50 values.

DnaN

Antibacterial drugs targeting essential multi-enzyme complexes are less prone to resistance development, since their malfunctioning is hard to bypass. In this context, the bacterial replisome machinery, which consists of at least twelve interacting enzymes that are highly conserved in bacteria, contains several attractive and promising antibacterial targets – including the bacterial β-sliding clamp DnaN. DnaN is a crucial subunit of the DNA polymerase III holoenzyme, preventing polymerase dissociation and enhancing polymerase activity. Furthermore, the β-sliding clamp shows interactions with a variety of other enzymes involved in replication and DNA repair processes. Its important functionality in the replication process and its highly conserved structure across bacterial species and its significant structural divergence to the mammalian counterpart (PCNA) make DnaN an attractive target for the treatment of various pathogens including Mycobacterium tuberculosis. Based on the natural product griselimycin (GM), a known DnaN binder, we adopted a semisynthetic approach, which resulted in a set of GM derivatives with promising antibacterial activities. Furthermore, we identified diverse small organic molecules binding to DnaN. The optimization of the most promising compounds is ongoing.

ColH

Clostridia represent a family of ubiquitously occurring gram-positive bacteria comprising perilous pathogens causing serious infectious diseases. The high lethality of these bacteria is related to collagenases, which are crucial for clostridial virulence, given their critical role in colonisation and evasion of host immune defence, acquisition of nutrients, facilitation of dissemination, or tissue damage during infection. The inhibition of these extracellular collagenases is conceptually attractive, as it does not attack the pathogen directly but rather blocks the colonisation and infiltration of the host by the clostridia. Targeting extracellular enzymes has the added benefit that inhibitors do not need to cross the bacterial cell wall, which has been challenging in many cases. Clostridial collagenases are zinc metalloproteinases with a multi-domain organisation, homologues of which are also found in many bacilli. Our group was the first who published compounds showing not only a highly potent inhibition of clostridial and bacillal collagenases (ColH IC50 in nM range) but also a strong selectivity over human MMPs.

LasB

Pseudomonas aeruginosa (PA), a highly problematic gram-negative pathogen, which has been assigned critical priority by the WHO, is responsible for many nosocomial infections. The opportunistic pathogen is also commonly found in burns, and in lungs of COPD and cystic fibrosis patients. PA-derived virulence factors play pivotal roles in mechanisms mediating its pathogenesis and infectivity. The strategy to develop “pathoblockers” targeting such virulence factors is expected to leave the commensal microbiome intact and to be less prone to the development of resistance compared to conventional antibiotics. One of the major virulence factors of PA is the extracellular zinc-metalloprotease elastase LasB. LasB substantially contributes to disease progression in PA-infected individuals by facilitating host invasion and immune evasion, and was furthermore reported to be involved in the formation of PA biofilms. Inhibition of LasB is a promising strategy to effectively reduce virulence of PA without affecting viability of the pathogen and the host microbiome. Our most promising LasB inhibitors show nanomolar IC50 values and a promising safety profile.
