The epoxyalkanoyl derivatives were designed and synthesized as ACE inh
ibitors. Coupling of unsaturated carboxylic acids with amino acids and
following epoxidation with dimethyldioxirane gave the epoxyalkanoyls
with high yield. The inhibitory activity of synthesized compounds on a
ngiotensin converting enzyme was IC50 values of 0.06 similar to 5.5 mu
