There is a gigantic chemical universe of small-molecule compounds—an estimated 10 to the thirty third energy (or a billion trillion trillion) molecules—that may be manufactured utilizing natural chemistry. Trillions of those molecules may result in therapeutic advances. However as a result of measurement of this chemical universe, brute-force exploration of its contents is doomed to failure as a result of synthesis is time-consuming and resource-intensive. One other technique is required.

The purpose of recent drug discovery is to develop drugs which might be safely administered with minimal uncomfortable side effects whereas strongly binding to disease-associated proteins in our our bodies. And but regardless of a rising record of validated goal proteins within the wake of the Human Genome Undertaking, the speed of latest FDA approvals for novel small-molecule medicine has stagnated over the previous 15 years.
