Application

(S)-(-)-α-Amino-γ-butyrolactone hydrobromide may be used as a building block to prepare:
  • β-ketoamide N-acylated-L-homoserine lactones (AHLs) as quorum sensing molecules
  • p-coumaroyl-HSL (homoserine lactone)
  • calpain and lipid peroxidation inhibitors
Used to prepare pseudopeptide inhibitors for Ras farnesyl-protein transferase as well as selenomethionine.

Inhibitors of Ras farnesyl-protein transferase are described. These are reduced pseudopeptides related to the C-terminal tetrapeptide of the Ras protein that signals farnesylation. Deletion of the carbonyl groups between the first two residues of the tetrapeptides either preserves or improves
