One-Click Web Application for Lead Discovery and Off-Target Effects
Including more than 1,000,000 bioactivity values for over 400,000 compounds associated with 3,500 protein targets*
In one-click a user can query:
- Protein targets to determine potential lead compounds for that target.
- Drugs to determine potential off-targets for which that drug might be associated.
- Disease pathways to determine lead compounds to modulate druggable targets in a disease of interest.
Plus many useful features to facilitate analysis such as downloadable spreadsheets and knowledge graphs.

CarlsbadOne is a one-step, bioactivity data-mining,evidence-driven application for biophamaceutical knowledge discovery via cheminformatics, chemogenomics and systems pharmaco-informatics.CARLSBAD = Confederated Annotated Research Libraries for Small molecule BioActivity Data.This web app queries the CARLSBAD database, which consists of targets, small molecules, bioactivities, related data, and chemical patterns comprised of scaffolds and MCES clusters.
- Disease-query mode: A single disease is the query. Diseases are from KEGG. KEGG also reports linked genes,which reference proteins via NCBI_GI and Uniprot IDs, and thereby CARLSBAD targets.The one-click network includes those targets, active compounds, their CCPs, and neighbor compounds.
- Drug-query mode: A single drug is the query. All targets for which the drug is active are included in the retrieved subnet. In addition, targets are included for which the active compounds are associated with the drug query via chemical patterns.
- Target-query mode: A single protein target is the query. All active compounds are included in the retrieved subnet.In addition, compounds are included which are associated with the active compounds via chemical patterns.
Relationship to Query (R2Q) – Targets and compounds found each have a relationship to the query, and in Carlsbad these relationships are either:
- Empirical – related via empirical activity data.
- Hypothesis – related via common chemical pattern (CCP) and empirical data.
Relationships generally also vary in network distance. However, in CarlsbadOne, to be regarded as empirical, entities must be associated by only ONE link of each type(e.g. target→compound→target).
Filters: Minimum scaffold weight: Scaffold-compound associations are weighted based on an approximation of the fraction of compound heavy atoms which are in the scaffold. Lower weights are thus correlated with weaker associations of less significance. Currently, this filter affects both the known active compounds and scaffold-associated unknowns.
Reduced-graph representations – To facilitate effective visualization of large networks, reduced-graph representations are available:
- Targets-only: target-target edges represent shared compounds.Activity profile information is reflected via visual cues (e.g. target-node size).
- Targets-and-CCPs: compounds are hidden and represented via their CCPs. Target-target edges representing shared compounds included.

Note to experienced CARLSBAD users about CarlsbadOne
The newly named CarlsbadOne web app responds to the needs and feedback of users,by providing a unified portal, designed for usability and simplicity,with useful, relevant results for scientifically meaningful queries.Specifically, this means:
- One webapp UI for query and network viewing via CytoscapeWeb.
- One step, one topic query logic, with queries defined by one disease, drug, or target.
- One degree of separation via chemical pattern associations to novel target/compound hypotheses.
- One unified, coherent data resource.
- Step One for bioactivity knowledge discovery.
The previous SNAKE→XGMML → Cytoscape → Carlsbad-Plugin workflow remains the most powerful and flexible way to utilize Carlsbad. However, even for advanced users with complex queries, CarlsbadOne can provide an effective starting point for initial and exploratory data analysis.
