Summary: | [Display omitted]
Designer fluoropeptidomimetics as protease inhibitors are revealed. The key peptidomimetic region in the inhibitors contains a ‘–CHF–S–’ moiety and is designed to mimic the tetrahedral oxyanion species during the hydrolysis of a peptide bond. Designed fluoropeptidomimetics in aqueous methanol slowly (in several hours to days) yielded the corresponding methyl ether and/or the oxazole derivatives after cyclization. Alkyl substitutions at the C-2 position exhibited enhanced aqueous stability. Nature of ‘–CHF–S–’ moiety and the stabilities of various fluoropeptidomimetics in aqueous solution are disclosed in detail. Fluoropeptidomimetics containing bulky substitutions at P1 such as compounds
15 and
16 exhibited time-dependent loss of activities against chymotrypsin, up to 67% and 79% with a
K
i of 63 and 120
μM, respectively. Fluoropeptidomimetics are a novel class of protease inhibitors and the next generation of fluoropeptidomimetics should incorporate enhanced stability. |
