Orion® Ready-for-Search Library Collection

Making your large scale virtual screening faster and easier

Orion provides a single point of access to various databases, including commercial vendors’ libraries, making your large scale virtual screening faster and easier.

You no longer need to access different vendors’ sites or manually process their data. Orion does the work for you! This enables you to efficiently perform structure-based and ligand-based searches by 2D similarity, 3D shape (FastROCS™), and 3D docking (Gigadock™), at an ultra large scale.

Through Orion, you can rapidly search billions of stereoenumerated molecules, encompassing tens of billions of conformers. This means you could identify promising drug-like molecules from billions of compounds in seconds (for 2D) and in as little as 30 minutes (for 3D) at a fraction of the cost of in vitro high-throughput screening assays.
