Abstract
The syntheses of Z-Leu-Leu-Tyr-CH2F (1) and Z-Tyr-Ala-CH2F (3) are described. The ability of Z-Leu-Leu-Tyr-CH2F (1) and Z-Leu-Tyr-CH2F (2) to inactivate in vitro calcium-activated proteinase from chicken gizzard are compared. Like the analogous diazomethyl ketones 4 and 5, these inhibitors were also found to inactivate cathepsin L in common with other inhibitors under current investigation. However, other specific inactivators for cathepsin L are available, for example, the fluoromethyl ketone 3 and diazomethyl ketone 6 of Z-Tyr-Ala-OH, which have no effect on the calcium-activated proteinase and therefore provide control inhibitors for observations made with Z-Leu-Leu-Tyr-CH2F (1).Entities:
