These designs are based on a generative machine learning model trained on very broad collection of known anti-viral compounds (HIV-1 Protease inhibitors, Ebola and Herpes antivirals, ...) and a hand curated selection of related molecules. The set of molecules generated by this model are then scored on chemical similarity to the COVID-19 / SARS-CoV-2 protease transition state analogue inhibitor template generated by the Quantum Corona project. The resulting high-scoring molecules were filtered on a series of AMDE and toxicity conditions, including Veber, Egan and Muegge violations. All molecules presented here are P-glycoprotein substrates, have a high GI absorption and have a favorable bioavailability score. The final subsection of molecules presented here was decided on by hand based on a range of factors including synthetic accessibility and some diversity measures.
Special thanks to Jeriek Van den Abeele at UiO's Department of Physics for computational support and to Jarvist Moore Frost at Imperial College London's Blackett Laboratory for kick-starting the the Quantum Corona project and making the protease transition state analogue inhibitor template widely available.
