Virtual Screening in Drug Discovery Computational methods can be used to predict or simulate how a particular compound interacts with a given protein target. VS takes place at the early discovery phase, in which the most promising lead compounds are found in large chemical databases. As an alternative or complementary approach to high-throughput screening (HTS) assays with high cost and low hit rate, virtual screening is an efficient computational method to identify drug candidates in silico from large chemical compound databases. Virtual screening (VS) has emerged in drug discovery as a powerful computational approach to screen large libraries of small molecules for new hits with desired properties that can then be tested experimentally. This method can screen only thousands of compounds at a time, which is a tiny fraction of the compounds that can be screened using AI. Therefore, a new process was developed in drug discovery termed hit-to-lead (H2L), or more fully, hit series-to-lead optimisation. The conventional virtual screening approach requires sequential.
