Going Barcode-Free: Screening Massive Small Molecule Libraries for Early Drug Discovery

Our recent study co-authored by researchers at Bright Giant, FSU Jena, Leiden University and Oncode Institute introduces a major leap forward in affinity selection screening for early drug discovery: Self-Encoded Libraries. Our approach uses advanced mass spectrometry to screen hundreds of thousands of small molecules in a single experiment, bypassing the significant limitations of traditional high-throughput screening as well as affinity selection with barcoded libraries. It allows drug discovery teams to identify high-affinity drug candidates faster, more affordably, and against targets previously inaccessible to common screening methods.

How to Constrain the Molecular Structure Search Space with Chemical Labeling

Unlocking the chemical ‘dark matter’ in metabolomics is a persistent challenge. A new approach addresses this by integrating derivatisation reactions for chemical labeling directly into the mass spectrometry workflow. It provides crucial structural information which is fed into small molecule annotation tools like SIRIUS to significantly constrain the molecular structure search space and boost annotation accuracy, even for previously undiscovered compounds. This powerful approach offers a scalable solution to unlock the vast, uncharted chemical space of the metabolome.

Unlocking a Greater Perspective: Mapping the Chemical Space of Biomes Using SIRIUS

Untargeted mass spectrometry is a powerful tool for analyzing the immense chemical complexity of natural environments. However, interpreting such large datasets remains a significant challenge. To overcome this, researchers have developed an innovative approach using SIRIUS that prioritizes chemical profiling over exhaustive identification. This method allows for more effective comparisons of (micro-)biomes, providing deeper insights into biochemical diversity across different environments.

Why Training Data Matters: Exploring Coverage Bias in Small Molecule Machine Learning

Machine learning is transforming analytical chemistry by enabling predictions of small molecule properties, crucial for drug development and other applications. However, ensuring reliable results requires careful selection of training data to avoid biases that can mislead models. Here, we explain why it was important to prepare high-quality training datasets for the machine learning methods in SIRIUS, especially given that many widely used datasets fail to evenly represent the diversity of biomolecular structures.
