## 🔧 Technical Implementation

### DrugDesigner V2 Architecture

#### Scaffold Libraries:
1. **Peptidominetics** (for GLP-1R, GIP)
   - Phe-Leu dipeptide
   - Trp-Gly dipeptide
   - Lys-Phe dipeptide
   - Ser-Val dipeptide

2. **Kinase Inhibitors** (for cancer)
   - Imatinib-like
   - Erlotinib-like
   - Gefitinib-like

3. **GPCR Modulators** (allosteric PAMs)
   - Indole-based PAMs
   - Sulfonamide modulators
   - Benzimidazole derivatives

4. **Generic Drug-like**
   - Beta-blockers
   - Tropane alkaloids
   - Oxazoles, thiazoles

#### Validation Pipeline:
```python
1. Select scaffold from disease-specific library
2. Parse with RDKit: Chem.MolFromSmiles()
3. Sanitize: Chem.SanitizeMol()
4. PAINS check: FilterCatalog.GetMatches()
5. Lipinski validation: MW, LogP, HBD, HBA
6. Calculate properties: Descriptors.*
7. Estimate affinity based on properties
8. Return DesignedMolecule object
