title: New fluoroketones as human renin inhibitors.
abstract: Renin inhibition has been evaluated for a new class of fluorinated ketones, true analogues of peptides that have been retroinverted at the C-terminal position. The readily formed hydrate of the ketone is proposed to mimic the tetrahedral intermediate that occurs during the enzyme-catalyzed hydrolysis of amide linkage. From this series of compounds it appears that the number of reverted amide bonds is crucial in terms of activity. Furthermore, a shortening of the C-terminal part of our peptide analogues and the replacement of the leucine residue in P1 by a cyclohexylalanine leads to the tripeptide analogue 12 a potent renin inhibitor (IC50 = 3.5 x 10(-9) M).
