The peptide bond formation was achieved in solution phase using pentafluorophenyl ester activation of the N-protected amino acids. The analogues were tested for their ability to release thyrotropin and for CNS activities and proved to be fully inactive. %Z Z9: 1 WC: Chemistry, Applied; Chemistry, Multidisciplinary
