Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add zinc-database
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("zinc-database")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install zinc-database

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/zinc-database/SKILL.md https://app.decimal.ai/s/zinc-database/SKILL.md

Copy SKILL.md

Save it in your project, as

.claude/skills/zinc-database/SKILL.md

This gets SKILL.md only. The skill's 1 other file is not included.

curl "https://cartblanche22.docking.org/substance/random.txt:count=1000&subset=lead-like&output_fields=zinc_id,smiles,tranche"

Common Workflows

Workflow 1: Preparing a Docking Library

Define search criteria based on target properties or desired chemical space

Query ZINC22 using appropriate search method:

# Example: Get drug-like compounds with specific LogP and MW
curl "https://cartblanche22.docking.org/substance/random.txt:count=10000&subset=drug-like&output_fields=zinc_id,smiles,tranche" > docking_library.txt

Parse results to extract ZINC IDs and SMILES:

import pandas as pd

# Load results
df = pd.read_csv('docking_library.txt', sep='\t')

# Filter by properties in tranche data
# Tranche format: H##P###M###-phase
# H = H-bond donors, P = LogP*10, M = MW

Download 3D structures for docking using ZINC ID or download from file repositories

Workflow 2: Finding Analogs of a Hit Compound

Obtain SMILES of the hit compound:

hit_smiles = "CC(C)Cc1ccc(cc1)C(C)C(=O)O"  # Example: Ibuprofen

Perform similarity search with distance threshold:

curl "https://cartblanche22.docking.org/smiles.txt:smiles=CC(C)Cc1ccc(cc1)C(C)C(=O)O&dist=5&output_fields=zinc_id,smiles,catalogs" > analogs.txt

Analyze results to identify purchasable analogs:

import pandas as pd

analogs = pd.read_csv('analogs.txt', sep='\t')
print(f"Found {len(analogs)} analogs")
print(analogs[['zinc_id', 'smiles', 'catalogs']].head(10))

Retrieve 3D structures for the most promising analogs

Workflow 3: Batch Compound Retrieval

Compile list of ZINC IDs from literature, databases, or previous screens:

zinc_ids = [
    "ZINC000000000001",
    "ZINC000000000002",
    "ZINC000000000003"
]
zinc_ids_str = ",".join(zinc_ids)

Query ZINC22 API:

curl "https://cartblanche22.docking.org/substances.txt:zinc_id=ZINC000000000001,ZINC000000000002&output_fields=zinc_id,smiles,supplier_code,catalogs"

Process results for downstream analysis or purchasing

Workflow 4: Chemical Space Sampling

Select subset parameters based on screening goals:
- Fragment: MW < 250, good for fragment-based drug discovery
- Lead-like: MW 250-350, LogP ≤ 3.5
- Drug-like: MW 350-500, follows Lipinski's Rule of Five

Generate random sample:

curl "https://cartblanche22.docking.org/substance/random.txt:count=5000&subset=lead-like&output_fields=zinc_id,smiles,tranche" > chemical_space_sample.txt

Analyze chemical diversity and prepare for virtual screening

Output Fields

Customize API responses with the output_fields parameter:

Available fields:

zinc_id: ZINC identifier
smiles: SMILES string representation
sub_id: Internal substance ID
supplier_code: Vendor catalog number
catalogs: List of suppliers offering the compound
tranche: Encoded molecular properties (H-count, LogP, MW, reactivity phase)

Example:

curl "https://cartblanche22.docking.org/substances.txt:zinc_id=ZINC000000000001&output_fields=zinc_id,smiles,catalogs,tranche"

Tranche System

ZINC organizes compounds into "tranches" based on molecular properties:

Format: H##P###M###-phase

H##: Number of hydrogen bond donors (00-99)
P###: LogP × 10 (e.g., P035 = LogP 3.5)
M###: Molecular weight in Daltons (e.g., M400 = 400 Da)
phase: Reactivity classification

Example tranche: H05P035M400-0

5 H-bond donors
LogP = 3.5
MW = 400 Da
Reactivity phase 0

Use tranche data to filter compounds by drug-likeness criteria.

Downloading 3D Structures

For molecular docking, 3D structures are available via file repositories:

File repository: https://files.docking.org/zinc22/

Structures are organized by tranches and available in multiple formats:

MOL2: Multi-molecule format with 3D coordinates
SDF: Structure-data file format
DB2.GZ: Compressed database format for DOCK

Refer to ZINC documentation at https://wiki.docking.org for downloading protocols and batch access methods.

Python Integration

Using curl with Python

import subprocess
import json

def query_zinc_by_id(zinc_id, output_fields="zinc_id,smiles,catalogs"):
    """Query ZINC22 by ZINC ID."""
    url = f"https://cartblanche22.docking.org/[email protected]_id={zinc_id}&output_fields={output_fields}"
    result = subprocess.run(['curl', url], capture_output=True, text=True)
    return result.stdout

def search_by_smiles(smiles, dist=0, adist=0, output_fields="zinc_id,smiles"):
    """Search ZINC22 by SMILES with optional distance parameters."""
    url = f"https://cartblanche22.docking.org/smiles.txt:smiles={smiles}&dist={dist}&adist={adist}&output_fields={output_fields}"
    result = subprocess.run(['curl', url], capture_output=True, text=True)
    return result.stdout

def get_random_compounds(count=100, subset=None, output_fields="zinc_id,smiles,tranche"):
    """Get random compounds from ZINC22."""
    url = f"https://cartblanche22.docking.org/substance/random.txt:count={count}&output_fields={output_fields}"
    if subset:
        url += f"&subset={subset}"
    result = subprocess.run(['curl', url], capture_output=True, text=True)
    return result.stdout

Parsing Results

import pandas as pd
from io import StringIO

# Query ZINC and parse as DataFrame
result = query_zinc_by_id("ZINC000000000001")
df = pd.read_csv(StringIO(result), sep='\t')

# Extract tranche properties
def parse_tranche(tranche_str):
    """Parse ZINC tranche code to extract properties."""
    # Format: H##P###M###-phase
    import re
    match = re.match(r'H(\d+)P(\d+)M(\d+)-(\d+)', tranche_str)
    if match:
        return {
            'h_donors': int(match.group(1)),
            'logP': int(match.group(2)) / 10.0,
            'mw': int(match.group(3)),
            'phase': int(match.group(4))
        }
    return None

df['tranche_props'] = df['tranche'].apply(parse_tranche)

Best Practices

Query Optimization

Start specific: Begin with exact searches before expanding to similarity searches
Use appropriate distance parameters: Small dist values (1-3) for close analogs, larger (5-10) for diverse analogs
Limit output fields: Request only necessary fields to reduce data transfer
Batch queries: Combine multiple ZINC IDs in a single API call when possible

Performance Considerations

Rate limiting: Respect server resources; avoid rapid consecutive requests
Caching: Store frequently accessed compounds locally
Parallel downloads: When downloading 3D structures, use parallel wget or aria2c for file repositories
Subset filtering: Use lead-like, drug-like, or fragment subsets to reduce search space

Data Quality

Verify availability: Supplier catalogs change; confirm compound availability before large orders
Check stereochemistry: SMILES may not fully specify stereochemistry; verify 3D structures
Validate structures: Use cheminformatics tools (RDKit, OpenBabel) to verify structure validity
