Combinatorial carbohydrate chemistry.

Modern organic/medicinal chemistry is undergoing a “cultural revolution” in the way new drugs are discovered and developed. Instead of discrete synthess and biological screening of individual compounds, which often takes years to identify and optimize leads, the currently developing technology called “combinatorial chemistry” can rapidly provide large numbers of chemicals (libraries) in a short time. In conjunction with these new synthetic methods, high-throughput screening (HTS) can rapidly screen the libraries produced, and in so doing, can provide information for optimizing lead compounds. This is going to lighten the increasing burden traditional drug development places on the pharmaceutical industry. For this reason, the generation of chemical libraries through combinatorial chemistry, including parallel synthesis, is making explosive progress both in academic and industrial areas in the last two years, especially for creating peptide, nucleotide and small molecule libraries. A number of excellent reviews1 on this field have appeared.
