Special Issue Information

Dear Colleagues,

Nature is the most important source of new bioactive compounds, and the field of natural product research is continuously developing. With an extensive and diverse chemical landscape, Nature holds great promise for future drug discovery. However, natural drug discovery has often been described as finding the needle in a haystack. The challenges encountered have led to the development of various methodologies for discovering bioactive molecules with new modes of action. In fact, with an ever-increasing need for new drugs, the development of new and efficient strategies and methods for drug discovery from Nature is pivotal for our success.

This Special Issue 'Current State-of-the-Art Methodologies for Drug Discovery from Nature' aims to serve as a platform for the natural products research society to share recent advancements in the field. These include, but are not limited to, technical advancements, screening strategies and platforms, biotechnological methodologies, and promising natural product sources.

In this context, we welcome high-quality contributions, from basic or applied scientists, describing new methodologies in natural product drug discovery, as well as review papers concerning specific areas within this field.

With the identification of novel antibiotics from nature being pivotal in the fight against human pathogenic bacteria, there is an urgent need for effective methodologies for expedited screening of crude extracts. Here we report the development and validation of a simple and dye-free antimicrobial assay in 96-well microplate format, for both determination of IC50 values and high-resolution inhibition profiling to allow pin-pointing of bioactive constituents directly from crude extracts. While commonly used antimicrobial assays visualize cell viability using dyes, the developed and validated assay conveniently uses OD600 measurements directly on the fermentation broth. The assay was validated with an investigation of the inhibitory activity of DMSO against Staphylococcus aureus, temperature robustness, interference by coloured crude extracts as well as inter-day reproducibility. The potential for high-resolution S. aureus growth inhibition profiling was evaluated on a crude extract of an inactive Alternaria sp., spiked with ciprofloxacin. Full article

The main challenge of plant chemical diversity exploration is how to develop tools to study exhaustively plant tissues. Their sustainable sourcing is a limitation as bioguided strategies and dereplication need quite large amounts of plant material. We examine if alternative solutions could overcome these difficulties by obtaining a secure, sustainable, and scalable source of tissues able to biosynthesize an array of metabolites. As this approach would be as independent of the botanical origin as possible, we chose eight plant species from different families. We applied a four steps culture establishment procedure, monitoring targeted compounds through mass spectrometry-based analytical methods. We also characterized the capacities of leaf explants in culture to produce diverse secondary metabolites. In vitro cultures were successfully established for six species with leaf explants still producing a diversity of compounds after the culture establishment procedure. Furthermore, explants from leaves of axenic plantlets were also analyzed. The detection of marker compounds was confirmed after six days in culture for all tested species. Our results show that the first stage of this approach aiming at easing exploration of plant chemodiversity was completed, and leaf tissues could offer an interesting alternative providing a constant source of natural compounds.
