It streamlines the process of compound discovery for researchers and developers in the pharmaceutical industry, enhancing their ability to explore chemical diversity and identify potential drug candidates.

FAQ

How can I access the ZINC database?

You can access the ZINC database through the web interface at https://zinc.docking.org/ or programmatically via the CartBlanche22 API.

What types of searches can I perform?

You can perform searches by ZINC ID, SMILES notation, and supplier codes to retrieve specific compounds or explore chemical diversity.

Are there any limitations on the API usage?

The API allows for customizable search fields and returns data in text or JSON format, but ensure to check the documentation for any usage limits.

Can I conduct similarity searches using the API?

Yes, you can perform similarity searches using SMILES with optional distance parameters to find compounds with structural similarities.

What versions of the ZINC database are available?

The skill primarily focuses on ZINC22, the current version, but also supports queries for ZINC20 and ZINC15.
