In the vital search for active compounds, there is great value in any approach that can focus experimental programs on the likeliest success routes, or that can deliver breakthrough insights. Machine learning is one such technology, with the potential to extract more value from existing data in order to guide drug discovery programs. But this data is often sparse and noisy – posing challenges to conventional machine learning and data analysis approaches. The Alchemite™ technology can master such data and, in collaboration with Optibrium, it is helping to reduce costs and optimise the drug discovery process.
Active learning for drug discovery with Cerella
Intellegens partners with Optibrium to embed the Alchemite™ deep learning algorithms within Cerella™ – a software platform for active learning in drug discovery. You can gain more value from your compound data, capturing complex relationships between structures, activities and other properties on a scale that cannot be achieved using conventional tools and supporting chemical space exploration beyond conventional QSAR models. Cerella™, powered by Alchemite™, increases confidence in decision making and lead optimisation and enables you to reduce costs and accelerate discovery cycles by targeting experimental resources more effectively.
Case study: Identifying a novel antimalarial compound
Intellegens succeeded with Optibrium in a global challenge organised by the Open Source Malaria consortium to design new antimalarial compounds with a novel mechanism of action, despite the sparsity of available experimental bioactivity data. The active compound identified by Alchemite™ deep learning as most likely to succeed was progressed through to synthesis and testing. Predictions from Alchemite™ were validated, and outperformed four alternative machine learning approaches assessed by the consortium.
