         “This was identified from a large screen of compounds
      from  the  Calibr  library  at  Scripps  Research,  which  is
      comprised of 11,000 drug-like molecules,” Bush said.
         From that initial screen, they identified 69 compounds
      that inhibited translation of the toxic C9 mutation. They
      then further refined the compounds by eliminating those that
      could not cross the blood-brain barrier based on size, weight,
      structure and other factors. This resulted in 16 candidate
      compounds, one of which was selected for further refinement
      based on its potency and structural simplicity.
