ZINC Database

Overview

ZINC is a freely accessible repository of 230M+ purchasable compounds maintained by UCSF. Search by ZINC ID or SMILES, perform similarity searches, download 3D-ready structures for docking, discover analogs for virtual screening and drug discovery.

When to Use This Skill

This skill should be used when:

• Virtual screening: Finding compounds for molecular docking studies
• Lead discovery: Identifying commercially-available compounds for drug development
• Structure searches: Performing similarity or analog searches by SMILES
• Compound retrieval: Looking up molecules by ZINC IDs or supplier codes
• Chemical space exploration: Exploring purchasable chemical diversity
• Docking studies: Accessing 3D-ready molecular structures
• Analog searches: Finding similar compounds based on structural similarity
• Supplier queries: Identifying compounds from specific chemical vendors
• Random sampling: Obtaining random compound sets for screening
