Substructure-Activity Relationship

Discipline: Medicinal Chemistry | Tools Used: 4 | Servers: 3

Description

Analyze substructure-activity: ChEMBL substructure search, activity data, PubChem compounds, and similarity.

Tools Used

• get_substructure_by_smiles from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL
• search_activity from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL
• search_pubchem_by_smiles from pubchem-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/8/Origene-PubChem
• calculate_smiles_similarity from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool

Workflow

1. Search ChEMBL by substructure
2. Get bioactivity data for hits
3. Search PubChem for related compounds
4. Compute similarity matrix

Test Case

Input

{
    "smiles": "c1ccc2[nH]ccc2c1"
}

Expected Steps

1. Search ChEMBL by substructure
2. Get bioactivity data for hits
3. Search PubChem for related compounds
4. Compute similarity matrix

Usage Example

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