Molecular Representation, Similarity and Search

submitted by: jcbradley
Rajarshi Guha presents at the final fall 09 Chemical Information Retrieval class at Drexel University on December 3, 2009. The audio for the first 45 seconds is a little off but the rest is fine. Implicit and explicit molecular representations in 1D, 2D and 3D formats are introduced. Approaches to quantifying molecular similarity using fingerprinting are discussed, such as the Tanimoto index. The relevance of these methods to drug design in terms of virtual screening and QSAR is explored....

Mel Reichman on Pool Shark’s Cues for More Efficient Drug Discovery

submitted by: jcbradley
Mel Reichman, senior investigator and director of the LIMR Chemical Genomics Center at the Lankenau Institute for Medical Research presents at the chemistry department at Drexel University on November 12, 2009. Introduction by Jean-Claude Bradley. Modern drug discovery by high-throughput screening (HTS) begins with testing hundreds of thousands of compounds in biological assays. The confirmed hit rate for typical HTS is less than 0.5%; therefore, 99.5% of the costs of HTS are for...
