Prestwick Chemical Library®

The Prestwick Chemical LibraryThe Prestwick Chemical Library® contains 1280 small molecules, 100% approved drugs (FDA, EMA and other agencies), 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.

What's the ideal use of the library ?

The strategy we recommend is the "SOSA Approach" (C.G. Wermuth, J. Med. Chem. 2004, 47, 1303-1314). It consists of submitting to the target only a limited number of highly diverse drug molecules for which bioavailability and toxicity studies have already been performed and which have proven usefulness in humans. 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. It can be noticed that, if the initial hit has sufficient affinity for the target, it could be immediately tested in patients.

How provided ?

The Prestwick Chemical Library® comes in two different presentations, either in DMSO solution and therefore ready for screening, or in powder form. DMSO libraries are supplied at a precise 10 mM concentration with volume offerings tailored to suit modern screening and assay development platforms. Please contact us for more details on commercial and custom volume options. In powder packaging, compounds are supplied as dry powder in vials with quantities ranging from 10 to 100mg of substance.

A database ready for use

The Prestwick Chemical Library® is provided with a standard data file (SDF) containing more than 50 fields in a hierarchical structure that can be individually customized (some data are pre-registered). A database in DB as well as in XLS format is offered as well. Therefore, each library is supplied with a database containing structures, chemical names and smiles of the compounds of the library, as well as useful physicochemical and biological data, literature references and precautions.

Additional amounts of substances

For all the active substances of the Prestwick Chemical Library®, additional amounts up to 100mg can be provided at cost.

The Library is sold with "no strings attached" (i.e. no royalties or milestones are requested). © 2006 | Privacy policy | Site Map
