Drug Discovery Resources

MicroSource Discovery Systems, Inc. (MDSI) provide diverse libraries of FDA-approved drugs synthetic compounds, and natural products. Their test compounds are supplied in a “ready-to-use” microplate format. The US Drug Collection is an important collection of 1040 drugs that have reached clinical trial stages in the USA. Each compound has been assigned USAN or USP status and is included in the USP Dictionary (U.S. Pharmacopeia, 2005), the authorized list of established names for drugs in the USA.

The Prestwick Chemical Library® contains 1120 small molecules, 90% being marketed drugs and 10% bioactive alkaloids or related substances, thus it presents the greatest possible degree of drug-likeliness. The active compounds were selected for their high chemical and pharmacological diversity as well as for their known bioavailability and safety in humans. The Prestwick Chemical Library ® was designed to reduce the risk of "low quality" hits, reduce the cost of the initial screening, and accelerate lead discovery. This initial screening will provide hits that will then be used as starting points for a drug optimization program which will rely on medicinal chemistry expertise. If an initial hit has sufficient affinity for the target, it could be immediately tested in patients.
