Title: Results From the World's Largest Distributed Prospective Application of Machine Learning to Small-Molecule Hit Discovery
Division: Computers in Chemistry
We report here the results from more than 100 prospective applications of machine-learning to small-molecule hit-discovery. Physical high-throughput screens are no longer a viable option for early-stage drug discovery because synthesized-on-demand ultra-large screening libraries (ULSL), which cover tens of billions of molecules, are too big for brute-force physical screening. Effectively exploring ULSL requires extraordinarily accurate algorithms, to avoid an overwhelmingly large number of false-positives because of the magnitude of the explored space. While machine learning tools promise to revolutionize drug discovery in precisely this manner, it has been extremely challenging to evaluate their actual prospective performance. We showed that the excellent performance reported on standard medicinal chemistry benchmarks are likely due to weaknesses in the design of these benchmarks, rather than the generalizability of the algorithms. Therefore, we have been running the largest assessment of machine learning for hit discovery in history, comprising over 700 projects on 575 targets with 330 universities in 40 countries. Our first 100+ results empirically demonstrate the viability of our machine-learning technology as a replacement for high-throughput screens.
Our team is comprised of over 30 PhD scientists who contribute to a high-performance academic-like culture that fosters robust scientific and technical excellence. We strongly believe that data wins over opinions, and aim for as little dogma as possible in our decision making. Learn more about our team and opportunities at Atomwise.
