Novel cyclohexapeptide has been synthesized by replacing the unusual amino acids (dolaphenvaline and dolaphenleuine) of dolastatin 16 with (±)-cis-exo-norbarnane and phenyl alanine amino acids. Novel cyclic hexapeptide alongwith dimers, tetramers composed of alternating L-proline subunits have been synthesized in solution phase and well characterized.
