The FieldFocus concept of biologically-targeted libraries builds upon BioFocus DPIs proven success in designing high efficiency lead-finding libraries. The FieldFocus Ion Channel (FFI) libraries are designed using Cressets proprietary molecular field technology, creating what can be described as a proteins-eye view of ligands. Library FFI01 contains approximately 500 novel, drug-like molecules with scaffolds unique for ion channels; it is available on a non-exclusive, easy access basis.
