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. %J JOURNAL FUR PRAKTISCHE CHEMIE-CHEMIKER-ZEITUNG %D 1994 %A Somlai Csaba %A BalĂĄspiri L %T Synthesis of Analogues of Thyrotropin-Releasing Hormone %L publicatio31990 %V 336
