# Chemical Patent & Novelty Analysis

**Discipline**: Patent Chemistry | **Tools Used**: 4 | **Servers**: 3

## Description

Analyze chemical novelty: PubChem substructure CAS search, ChEMBL similarity search, compound synonyms, and literature.

## Tools Used

- **`get_substructure_cas`** from `pubchem-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/8/Origene-PubChem`
- **`get_similarity_by_smiles`** from `chembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL`
- **`get_compound_synonyms_by_name`** from `pubchem-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/8/Origene-PubChem`
- **`search_literature`** from `server-1` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory`

## Workflow

1. Search CAS by substructure
2. Search ChEMBL by similarity
3. Get compound synonyms
4. Search patent literature

## Test Case

### Input
```json
{
    "smiles": "c1ccc(-c2ccccc2)cc1",
    "compound_name": "biphenyl"
}
```

### Expected Steps
1. Search CAS by substructure
2. Search ChEMBL by similarity
3. Get compound synonyms
4. Search patent literature

## 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).
