Fluorinated Fragment Library

2 100 compounds

One of the powerful screening techniques widely used nowadays in fragment based drug discovery (FBDD) is 19F NMR spectroscopy. It has been appreciated because of the high speed of screening and sensitivity in detection of molecular interactions. Furthermore, involvement of fluorine atoms in binding with proteins (e.g. through carbonyls) has been recently acknowledged. It is also well known that fluorination often improves molecular and ADME/Tox profiles of the compounds making fluorinated fragments better starting points for hit-to-lead optimization.

Enamine is experienced in fluorine chemistry with over 50 scientific publications in this research area issued in past 10 years. Our chemists are heavily involved in researching on synthesis and new methodologies for introducing of fluorine atoms in wide range of aliphatic/aromatic heterocyclic cores and different side chains.
