Polypharmacology Analysis

Discipline: Pharmacology | Tools Used: 4 | Servers: 3

Description

Analyze a drug's multi-target pharmacology: get targets from ChEMBL, functional enrichment from STRING, and pathway links from KEGG.

Tools Used

• get_target_by_name from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL
• get_functional_enrichment from string-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/6/Origene-STRING
• kegg_link from kegg-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/5/Origene-KEGG
• get_mechanism_by_id from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL

Workflow

1. Get drug targets from ChEMBL
2. Run functional enrichment on targets
3. Link to KEGG pathways
4. Get mechanism details

Test Case

Input

{
    "drug_name": "imatinib"
}

Expected Steps

1. Get drug targets from ChEMBL
2. Run functional enrichment on targets
3. Link to KEGG pathways
4. Get mechanism details

Usage Example

Note: Replace <YOUR_SCP_HUB_API_KEY> with your own SCP Hub API Key. You can obtain one from the SCP Platform.
