Biognos AB is a CRO providing services in computational screening, both structure-based and ligand-based. We have 4 people working in the company and we have a computer cluster with 35 “real” cores. The structure based screening is performed using both commercial and public domain software. The dockings are done with large databases of commercially available compounds. Especially in cases when the structure of the target protein in unknown it is of interest to perform ligand-based screening. We can do this with large libraries also allowing for some flexibility in the ligand. Through ligand-based screening it is possible to achieve scaffold hopping thus allowing reinforcement or circumvention of patents. We can also perform chemoinformatics services e.g. prediction ADME, diversity selection and nearest neighbour analysis. We work under CDA and we have no claims on IP.
