tooluniverse-drug-research

name	tooluniverse-drug-research
description	Generates comprehensive drug research reports with compound disambiguation, evidence grading, and mandatory completeness sections. Covers identity, chemistry, pharmacology, targets, clinical trials, safety, pharmacogenomics, and ADMET properties. Use when users ask about drugs, medications, therapeutics, or need drug profiling, safety assessment, or clinical development research.

Drug Research Strategy

Comprehensive drug investigation using 50+ ToolUniverse tools across chemical databases, clinical trials, adverse events, pharmacogenomics, and literature.

KEY PRINCIPLES:

1. Report-first approach - Create report file FIRST, then populate progressively
2. Compound disambiguation FIRST - Resolve identifiers before research
3. Citation requirements - Every fact must have inline source attribution
4. Evidence grading - Grade claims by evidence strength
5. Mandatory completeness - All sections must exist, even if "data unavailable"
6. English-first queries - Always use English drug/compound names in tool calls, even if the user writes in another language. Only try original-language terms as a fallback. Respond in the user's language

---

Critical Workflow Requirements

1. Report-First Approach (MANDATORY)

DO NOT show the search process or tool outputs to the user. Instead:

1. Create the report file FIRST - Before any data collection, create a markdown file:

   • File name: [DRUG]_drug_report.md (e.g., metformin_drug_report.md)
   • Initialize with all 11 section headers from the template
   • Add placeholder text: [Researching...] in each section

2. Progressively update the report - As you gather data:

   • Update each section with findings immediately after retrieving data
   • Replace [Researching...] with actual content
   • The user sees the report growing, not the search process

3. Use ALL relevant tools - For comprehensive coverage:

   • Query multiple databases for each data type
   • Cross-reference information across sources
   • Use fallback tools when primary tools return limited data

2. Citation Requirements (MANDATORY)

Every piece of information MUST include its source. Use inline citations:

## 3. Mechanism & Targets

### 3.1 Primary Mechanism
Metformin activates AMP-activated protein kinase (AMPK), reducing hepatic glucose 
production and increasing insulin sensitivity in peripheral tissues.

*Source: PubChem via `PubChem_get_drug_label_info_by_CID` (CID: 4091)*

### 3.2 Primary Target(s)
| Target | UniProt | Activity | Potency | Source |
|--------|---------|----------|---------|--------|
| AMPK (PRKAA1) | Q13131 | Activator | EC50 ~10 µM | ChEMBL |
| Mitochondrial Complex I | - | Inhibitor | IC50 ~1 mM | Literature |

*Source: ChEMBL via `ChEMBL_get_target_by_chemblid` (CHEMBL1431)*

Citation Format

For each data section, include at the end:

---
**Data Sources for this section:**
- PubChem: `PubChem_get_compound_properties_by_CID` (CID: 4091)
- ChEMBL: `ChEMBL_get_bioactivity_by_chemblid` (CHEMBL1431)
- DGIdb: `DGIdb_get_drug_info` (metformin)
---

3. Progressive Writing Workflow

Step 1: Create report file with all section headers
        ↓
Step 2: Resolve compound identifiers → Update Section 1
        ↓
Step 3: Query PubChem/ADMET-AI/DailyMed SPL → Update Section 2 (Chemistry)
        ↓
Step 4: Query FDA Label MOA + ChEMBL activities + DGIdb → Update Section 3 (Mechanism & Targets)
        ↓
Step 5: Query ADMET-AI tools → Update Section 4 (ADMET)
        ↓
Step 6: Query ClinicalTrials.gov → Update Section 5 (Clinical Development)
        ↓
Step 7: Query FAERS/DailyMed → Update Section 6 (Safety)
        ↓
Step 8: Query PharmGKB → Update Section 7 (Pharmacogenomics)
        ↓
Step 9: Query DailyMed → Update Section 8 (Regulatory)
        ↓
Step 10: Query PubMed/literature → Update Section 9 (Literature)
        ↓
Step 11: Synthesize findings → Update Executive Summary & Section 10
        ↓
Step 12: Document all sources → Update Section 11 (Data Sources)

4. Report Detail Requirements

Each section must be comprehensive and detailed:

• Tables: Use tables for structured data (targets, trials, adverse events)
• Lists: Use bullet points for features, findings, key points
• Paragraphs: Include narrative summaries that synthesize findings
• Numbers: Include specific values, counts, percentages (not vague terms)
• Context: Explain what the data means, not just what it is

BAD (too brief):

### Clinical Trials
Multiple trials completed. Approved for diabetes.

GOOD (detailed with sources):

FDA Label Core Fields Bundle

For approved drugs, ALWAYS retrieve these FDA label sections early (after getting set_id from DailyMed_search_spls):

Critical Label Sections

Call DailyMed_get_spl_sections_by_setid(setid=set_id, sections=[...]) with these sections:

Phase 1 (Mechanism & Chemistry):

• mechanism_of_action → Section 3.1
• pharmacodynamics → Section 3.1
• chemistry → Section 2.4

Phase 2 (ADMET & PK):

• clinical_pharmacology → Section 4
• pharmacokinetics → Section 4.1-4.4
• drug_interactions → Section 4.3, 6.5

Phase 3 (Safety & Dosing):

• warnings_and_cautions → Section 6.3
• adverse_reactions → Section 6.1
• dosage_and_administration → Section 6.6, 8.2

Phase 4 (PGx & Clinical):

• pharmacogenomics → Section 7
• clinical_studies → Section 5.5
• description → Section 2.5 (formulation)
• inactive_ingredients → Section 2.5

Label Extraction Strategy

1. Get set_id: DailyMed_search_spls(drug_name)
   
2. Batch call for all core sections (or 3-4 calls with 4-5 sections each):
   DailyMed_get_spl_sections_by_setid(setid=set_id, sections=["mechanism_of_action", "pharmacodynamics", ...])
   
3. Extract and populate report sections as you retrieve data

This ensures you have authoritative FDA-approved information even if prediction tools fail.

Compound Disambiguation (Phase 1)

CRITICAL: Establish compound identity before any research.

Identifier Resolution Chain

1. PubChem_get_CID_by_compound_name(compound_name)
   └─ Extract: CID, canonical SMILES, formula
   
2. ChEMBL_search_compounds(query=drug_name)
   └─ Extract: ChEMBL ID, pref_name
   
3. DailyMed_search_spls(drug_name)
   └─ Extract: Set ID, NDC codes (if approved)
   
4. PharmGKB_search_drugs(query=drug_name)
   └─ Extract: PharmGKB ID (PA...)

Handle Naming Ambiguity

Issue	Example	Resolution
Salt forms	metformin vs metformin HCl	Note all CIDs; use parent compound
Isomers	omeprazole vs esomeprazole	Verify SMILES; separate entries if distinct
Prodrugs	enalapril vs enalaprilat	Document both; note conversion
Brand confusion	Different products same name	Clarify with user

Key API notes:

• FAERS analytics: ALL require operation parameter
• FAERS count tools: use medicinalproduct NOT drug_name
• DrugBank tools: ALL require query, case_sensitive, exact_match, limit (4 params)
• ADMETAI tools: smiles must be a list [smiles_string]
• PubMed: returns plain list, NOT {articles: [...]}
• DailyMed: get set_id first via DailyMed_search_spls, then call section tools

---

Common Use Cases

• Approved drug profile: Full 11-section report (emphasize clinical, FAERS, PGx)
• Investigational compound: Emphasize preclinical, mechanism, early trials; safety sparse
• Safety review: Deep dive FAERS + warnings + interactions + PGx
• ADMET assessment: Focus Sections 2 & 4; other sections brief
• Clinical landscape: Heavy Section 5; trial tables with phases/indications
