Build a multi-hop knowledge graph from any protein or compound

Chemical Data Extractor traverses public chemistry, proteomics and pathway sources from a single query, then exports the assembled graph as a workbook, CSV, GraphML, Cypher and more.

How it works, and what a hop is
  1. 1.Enter a protein (for example “tubulin” or “EGFR”) or a compound (for example “Aspirin”).
  2. 2.Leave the type on Auto to let the engine detect it, or set it yourself.
  3. 3.Choose an expansion depth — how many relationship steps to follow.
  4. 4.Run the search and watch the live log; download the exports when it finishes.
1-hop
Direct relationships only — e.g. Aspirin → COX-1. Fastest.
2-hop
One step further — e.g. Aspirin → COX-1 → prostaglandin pathway.
3-hop
Deep network — e.g. adds pathway-associated diseases.
4-hop
Maximum depth across all databases. Broadest and slowest.

Answers are generated from the current search context. Verify critical values against the exported files before citing them.

Ready when you are

Enter a protein or compound on the left and run a search. The engine expands the query across every connected database and streams its progress here, then lists the files you can download.

Searches run in parallel. If the engine is already at its concurrency limit, yours is queued and starts automatically.
