Abstract Scope |
Despite the vast chemical space (billions) that can be potentially explored as therapeutic agents, we remain severely limited in the search owing to the high computational cost of the popular docking simulations-based screening procedures. In addition, the screening procedures are limited to the already known chemical spaces. Here, we present a de novo design strategy that leverages artificial intelligence to discover new ligands targeting the spike protein (S-protein) of SARS-CoV-2 at its host receptor region or S -protein:Angiotensin converting enzyme 2 (ACE2) receptor interface. Our workflow integrates a Monte Carlo Tree Search algorithm (MCTS) with a multi-task neural network (MTNN) and recurrent neural networks (RNN) to sample the vast chemical space. We generate several new biomolecules that outperform FDA and non-FDA biomolecules from existing databases. Although we focus on therapeutic biomolecules, our AI strategy is broadly applicable for accelerated design and discovery of any chemical molecules with user-desired functionality. |
