Virtual Screening Service
-
Receptor-Based Virtual Screening
Virtual screening uses computer-based techniques to identify potential drug candidates from large compound libraries.
It predicts the binding affinity of a compound to a known drug target.
It can include structure-based or ligand-based screening methods, and is used to evaluate libraries of tens of millions of compounds.
This approach is time- and cost-effective, enabling the faster screening of potential ligands against a target compared to traditional experimental methods.
-
Ligand-Based Virtual Screening
Pharmacophore virtual screening rapidly and efficiently identifies potential drug candidates by analyzing key chemical features using computational methods.
Ligand-based screening methods are faster and more efficient than structure-based screening.
By analyzing the chemical features of effective drugs, this approach identifies novel ligands beyond known compounds.

Hyperscale Database Virtual Screening
Ultra-large library screening is applied to libraries containing a much larger number of compounds (often billions or more) than traditional virtual screening.
It uses advanced computing technologies and algorithms to process large amounts of data and enable high-throughput screening.
This method maximizes compound diversity and chemical space, facilitating the discovery of new compounds that traditional screening methods struggle to explore.
It utilizes state-of-the-art computing resources to explore a vast chemical space.
