Combinatorial chemistry has emerged as a powerful tool for accelerating drug discovery process. Compared to traditional drug discovery approach, which requires many days of work to synthesize and analyze a single new compound, combinatorial chemistry can produce and screen thousands of compounds in weeks
for the discovery of novel drug entities against various disease targets. The continuous development of high throughput bioassay screening formats coupled with human genomics as a potential source of new biological targets, has created an acute need for a large number of structurally diverse molecules.
