Combinatorial Chemistry & High Throughput Screening - Volume 3, Issue 5, 2000

Finding drugs that inhibit protein-protein interactions is usually difficult. While computer-aided design is used widely to facilitate the drug discovery process for protein targets with well-defined binding pockets, its application to the design of inhibitors targeting a protein surface is very limited. In this mini-review we address two aspects of this issue: firstly, we overview the current state of design methodology for inhibitors specific Read More

Many contemporary applications in computer-aided drug discovery and chemoinformatics depend on representations of molecules by descriptors that capture their structural characteristics and properties. Such applications include, among others, diversity analysis, library design, and virtual screening. Hundreds of molecular descriptors have been reported in the literature, ranging from simple bulk properties to elaborate thr Read More

Phage display libraries offer a strategy to isolate peptide ligands to target proteins and to define potential interaction sites between proteins. Recent studies have indicated a novel utility for phage display in that bacteriophage engineered to express peptide ligands to specific cell surface receptors are internalized by mammalian cells. Thus, reporter genes such as green fluorescent protein and lacZ harbored in the phage genome c Read More

Molecular diagnosis of complex inherited disorders, population screening of genetic diseases, studies of the genetic basis of variable drug response (pharmacogenetics) as well as discovery and investigation of new drug targets (pharmacogenomics) involve screening for mutations in multiple DNA samples. Furthermore, the development of a third generation of the human genome map, based on single nucleotide polymorphis Read More

In the past several years, a new set of technologies based on whole genome analysis have revolutionized the study of gene expression. These microarray or "gene chip" technologies, which arose out of the development of large-scale sequencing approaches, are now coming into increasing use, generating a far greater volume of data than the data representing the sequences themselves. This review focuses on the current Read More

Genomics has caused an explosion in the number of potential therapeutic targets with varying degrees of validated pathophysiology. Among the first applications of combinatorial chemistry in genomics-driven drug discovery is the search for surrogate ligands or substrates. In the event that no surrogate is found for molecular assays, more exotic functional screens in whole cells or model organisms are used. Protein-protein i Read More

The use of fluorescence polarization (FP) has increased significantly in the development of sensitive and robust assays for high throughput screening of chemical compound libraries during the past few years. In this study, we show that FP is a useful assay miniaturization technology for reagent reduction during high throughput screening. We developed and optimized several FP assays for binding to estrogen receptor ?? Read More
