# Compound-to-Drug Analysis Pipeline

**Discipline**: Drug Development | **Tools Used**: 4 | **Servers**: 4

## Description

Full compound-to-drug pipeline: name-to-SMILES conversion, structure analysis, drug-likeness, and FDA drug lookup.

## Tools Used

- **`NameToSMILES`** from `server-31` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/31/SciToolAgent-Chem`
- **`ChemicalStructureAnalyzer`** from `server-28` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/28/InternAgent`
- **`calculate_mol_drug_chemistry`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`
- **`get_drug_by_name`** from `chembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL`

## Workflow

1. Convert name to SMILES
2. Analyze chemical structure
3. Calculate drug-likeness
4. Search in ChEMBL drug database

## Test Case

### Input
```json
{
    "compound_name": "caffeine"
}
```

### Expected Steps
1. Convert name to SMILES
2. Analyze chemical structure
3. Calculate drug-likeness
4. Search in ChEMBL drug database

## Usage Example

> **Note:** Replace `sk-b04409a1-b32b-4511-9aeb-22980abdc05c` with your own SCP Hub API Key. You can obtain one from the [SCP Platform](https://scphub.intern-ai.org.cn).
