Synthesis of novel (±)-cis-exo-norbornane amino acid containing cyclic hexapeptide: Analogue of Dolastatin 16
1  NATIONAL INSTITUTE OF PHARMACEUTICAL EDUCATION AND RESEARCH, HYDERABAD-500037

Abstract:

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.

Keywords: Dolastatin 16, exo-norbornane amino acid, peptide synthesis, cyclic hexapeptide.
