Synthesis and some physicochemical properties of antamanide, retroantamanide, and perhydroantamanide

Summary

The synthesis of antamanide, retroantamanide, and perhydroantamanide has been effected. It has been shown that the inversion of the direction of acylation — the equilibrium interchange of the valine and alanine residues (retroantamanide) — lowers the stability of the complexes with sodium and potassium in ethanolic solutions, while the replacement of the phenyl groups by cyclohexyl groups has practically no effect on complex formation.
