The Top 200 drugs (158 unique structures) were combined with 769 medicinal chemistry structures from WOMBAT (by selecting the highest active compounds for each target) to define a high-activity chemical space. These 923 compounds were clustered according to the Molecular Design Limited (MDL) "drug like" keys using Mesa Analytics & Computing software. The 1-D representation of biological activity space can be used to visualize novel compounds (single-SMILES similarity mode in a web interface) using SimNav, the Similarity Navigator. We will present our experience with SimNav, an on-line product from the University of New Mexico and Harvard Medical School.

Acknowledgments: John and Norah MacCuish (Mesa Analytics & Computing) and Andrew Dalke (Dalke Scientific Software) have contributed in this project.
