Drug Discovery building blocks

Cheminformatics and Modeling Toolkits

The OpenEye toolkits are programming libraries for creating custom applications, scripts and/or web services. All of the toolkits are developed in C++ to ensure exceptional performance but are also available to developers in Python, Java, and .NET for maximum flexibility and utility. Each toolkit has its own well documented and stable API with extensive examples.
