Abstract: | An efficient method for the synthesis of some Gn-RH analogues based on Ugi reaction has been developed. Four-component reaction of N- and C-terminus peptides, aromatic aldehydes and isocyanides affords novel Gn-RH analogues derived from triptorelin and gonadorelin. All of the products were purified using preparative HPLC and the structures were assigned according to MALDI-mass spectrometry data. |
