    • Fluorinated aldehydes and ketones are more extensively hydrated than the non-fluorinated counterparts and are also more potent inhibitors of serineand metalloproteases. Despite the fact that these inhibitors are largely hydrated, it has been shown that inhibition occurs by binding of the aldehyde or ketone form to the active site and formation of a serine-bound hemiacetal or hemiketal, a Gelb, M.

    • Another potential contributing factor might involve disorder caused by a rapid conformational change of the inhibitor. Ab initio and DFT molecular modeling studies indicate that a model hemiketal of 4α can adopt two slightly different exo envelope conformations in which the chlorines show the greatest differences in position. The low energy difference (0.1 -0.3 kcal/mol) and the low energy barrier (0.4-0.8 kcal/mol) for interconversion support this hypothesis Figures S3 and S4, Supporting Information
