An improved total synthesis of the emetic toxin cereulide and the preparation of four lysine-linked cereulide analogues is described. The cereulide analogues are prepared by replacing one of the amino acid residues in cereulide with lysine. The cereulide analogues demonstrate ionophoric activity towards alkali metal ions and inorganic ammonium ions, and are currently being used to develop an enzyme-linked immunosorbent assay for cereulide.
Compounds of the formula ##STR1## wherein X is various amino or imino acids and esters are disclosed. These compounds are useful as anti-hypertensive agents due to their angiotensin converting enzyme inhibition activity and depending upon the definition of X may also be useful as analgesics due to their enkephalinase inhibition activity.
