Recently, halogen bonds have gained increased recognition as a useful molecular interaction in the life sciences and drug discovery. However, despite the potential of halogen moieties to positively affect ligand binding, standard libraries for fragment-based screening display very low number of compounds containing heavy halides. Halogen-enriched fragment libraries (HEFLibs) consist of chemical probes that allow to identify halogen bonds as one of the main features of the protein-ligand binding mode. Besides that, these fragment libraries provide smart starting points for hit-to-lead evolution.
Halogen-Enriched Fragment Library available from Reaxense consists of 2,659 fragment molecules facilitating the identification of favourable halogen bonds by sharing the advantages of classical fragment-based screening. Selected by modified Ro3 parameters, all compounds in this library contain at least one atom of halogen.
