Machine Learning Guided Peptide Drug Discovery Speeds up Lead
Identification as Demonstrated with Novel GLP-1R Agonists
We have developed streaMLine, an innovative platform for peptide drug discovery that greatly shortens the time from initial hit to clinical drug candidate. The platform allows for high throughput synthesis and screening. Thousands of peptides are systematically screened in in vitro assays and on chemical- and physical parameters, whereby the streaMLine platform enables complete sequence exploration and simultaneous optimization of key parameters.
We employ a fully digitalized laboratory system where detailed information on all aspects of a sample lifetime is tracked. This enables accurate distinction of key chemical peptide modification from artefact background effects, using a machine learning approach. This unique strategy for peptide screening integrates with state-of-the-art in vivo pharmacology facilities, including advanced animal models and rapid determination of PK/PD relationships.
Using the streaMLine platform, we developed novel GLP-1R agonists, to demonstrate how high throughput screening peptide libraries and machine learning guided drug design can be applied to accelerate drug discovery. We systematically synthesized and screened a total of 2,688 peptides in a parallelized optimization workflow. Using this approach, we identified a vast chemical solution space for generating novel GLP-1R agonists based on an alternative peptide starting point, that is, the secretin backbone. To validate the developed QSAR pipeline, we conducted an in-depth profiling of a
developed GLP-1R agonist that showed high receptor selectivity, attractive physicochemical properties and pharmacokinetic profiling, and a potent weight-lowering in vivo efficacy.
