Prestwick Drug-Fragment Library

Prestwick Drug-Fragment Library : 1456 fragments arising from smart fragmentationof approved drugs

Acknowledged as powerful tool for successful identification of lead series, fragment-based drug design is widely implemented in industry and academia. To meet researchers’ expectations, Prestwick Chemical medicinal chemists have designed a unique collection of 1456 small molecules (MW<300) arising from the smart fragmentation of approved drugs (up to year 2016).


Prestwick Drug-Fragment Library : key features
