Abstract
Kohonen neural networks generate projections of large data sets defined in high-dimensional space. The resulting self-organizing maps can be used in many applications in the drug discovery process, such as to analyze combinatorial libraries for their similarity or diversity and to select descriptors for structure−activity relationships. The ability to investigate thousands of compounds in parallel also allows one to conduct a study based on single-dose experiments of high-throughput screening campaigns, which are known to have a greater uncertainty than IC50 or Ki values. This is demonstrated here for a data set of 5513 compounds from one combinatorial library. Furthermore, a method was developed that uses self-organizing maps not only as an indicator of structure−activity relationships, but as the basis of a classification system allowing predictive modeling of combinatorial libraries.

Steffen Wagner, Raul Arce, Renato Murillo, Lothar Terfloth, Johann Gasteiger and Irmgard MerfortJournal of Medicinal Chemistry2008 51 (5), 1324-1332Sesquiterpene lactones are the active components of a variety of medicinal plants from the Asteraceae familiy. They possess biological activities such as the inhibition of NF-κB and the release inhibition of the vasoactive serotonin. On the basis of a ...

Ligand-Based Virtual Screening by Novelty Detection with Self-Organizing Maps
Dimitar Hristozov, Tudor I. Oprea, and Johann GasteigerJournal of Chemical Information and Modeling2007 47 (6), 2044-2062Ligand-Based Virtual Screening by Novelty Detection with Self-Organizing Maps
Dimitar Hristozov, Tudor I. Oprea, and Johann GasteigerJournal of Chemical Information and Modeling2007 47 (6), 2044-2062We describe a novel method for ligand-based virtual screening, based on utilizing Self-Organizing Maps (SOM) as a novelty detection device. Novelty detection (or one-class classification) refers to the attempt of identifying patterns that do not belong to ...

Ecker, and Johann GasteigerJournal of Medicinal Chemistry2007 50 (7), 1698-1702Self-organizing maps were trained to separate high- and low-active propafenone-type inhibitors of P-glycoprotein. The trained maps were subsequently used to identify highly active compounds in a virtual screen of the SPECS compound library.
