.In the early stage of drug development, high-throughput screening is carried out using experimental assays. It is currently estimated that there are over 1063 potential compounds as drug candidates. Consequently, there has been growing interest in virtual drug screening as a cost-effective and time-efficient approach. Virtual screening methods can be divided into two types: an AI-based approach, which leverages machine learning models trained on existing experimental data, and a docking simulation, which is based on three-dimensional structures of target proteins. Whereas various techniques have been proposed in both approaches, a significant gap still exists in the virtual and real-world scenarios, such as imbalanced data and dynamics properties of molecules. In this presentation, we will introduce our efforts in practical evaluation of protein-compound evaluation in both the AI-based and the structure-based approaches. In the former, we have improved the model's generalizability with self-training method to address the lack of experimentally validated negative samples in the public databases. In the latter, we have successfully achieved molecular dynamics-based protein-drug screening by utilizing the supercomputer Fugaku. These achievements represent significant advances in next-generation computer-assisted drug discovery.
