FeaturesProvenance: all data is interlinked with the original sourceDrill-down: interactive sorting based on public and private propertiesHousekeeping: put compounds in „buckets“ to retain an overviewSearching: based on similarity, substructure or related targetPersistence: store a session and resume work later

Workflow IStart with a single compound name or a SMILES string and extend the molecule set by related compounds:
a) Find target via assay data and load all compounds from OPS, which are active against this target
b) Start a similarity searchc) Define a substructure and start a substructure search

Workflow IIStart with target nameThe CBN loads the target information from OPS. On mouse click, all active compounds are loaded in the CBN.

Workflow IIIStart with a set of SMILES or a SD file:The given compounds are initialized by NAOMI and annotated with data from the OPS.

Example: Find new lead structures for CSF-1 receptor inhibitionStart the CBN: www.chembionavigator.orgSearch for CW-2580 (a highly selective kinase inhibitor)Select the compound and explore the available data on the compound panel on the left hand side Perform a substructure search on the entire compoundSwitch to table view (buttons in the upper right corner) and explore the new compounds -> for which protein are they identified as inhibitors?Select this protein (Pharmacology tab on the Compound Panel)Go the Target Panel and download all active compounds of the proteinDownload this compound set
