Notes:
The syntheses of seven tripeptide isomers containing L-histidine, L-proline and L-glutamic acid residues, the same as found in the natural thyrotropin-releasing hormone (TRH), are reported. In addition L-pyroglutamyl-L-histidyl-L-proline and its amide as well as Nα-acetyl-L-glutamyl-L-histidyl-L-proline are described. Whereas eight peptides are inactive and L-pyroglutamyl-L-histidyl-L-proline shows a slight TRH activity, L-pyroglutamyl-L-histidyl-L-proline-amide has the full biological activity of the isolated thyrotropin-releasing hormone and, at the present state of knowledge, seems to be identical with it.
