Lead Compound Optimization

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

Description

Optimize a lead compound: validate SMILES, compute drug-likeness, predict ADMET properties, and check ChEMBL bioactivity.

Tools Used

• is_valid_smiles from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• calculate_mol_drug_chemistry from server-2 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool
• pred_molecule_admet from server-3 (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/3/DrugSDA-Model
• search_activity from chembl-server (streamable-http) - https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL

Workflow

1. Validate SMILES
2. Calculate drug-likeness metrics
3. Predict ADMET
4. Search ChEMBL bioactivity

Test Case

Input

{
    "smiles": "CC(=O)Oc1ccccc1C(=O)O"
}

Expected Steps

1. Validate SMILES
2. Calculate drug-likeness metrics
3. Predict ADMET
4. Search ChEMBL bioactivity

Usage Example

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