The peptides Ac-D-2Nal-D-4ClPhe-D-3Pal-OH and Boc-D-2Nal-D-4ClPhe-D-3Pal-OH are intermediates useful in the synthesis of LHRH analogs by coupling with suitable heptapeptides, in particular with the heptapeptides P1-Ser(P2)-MMeTry(P3)-D-Lys(Nic)-Leu-Lys(iPr,P4)-Pro-D-AlaNH2 and P1-Ser(P2)-NMeTry(P3)-D-Asn-Leu-Lys(iPr,P4)-Pro-D-AlaNH2.
肽类Ac-D-2Nal-D-4ClPhe-D-3Pal-OH和Boc-D-2Nal-D-4ClPhe-D-3Pal-OH是在合成LHRH类似物中有用的中间体,通过与适当的七肽偶联,特别是与七肽P1-Ser(P2)-MMeTry(P3)-D-Lys(Nic)-Leu-Lys(iPr,P4)-Pro-D-AlaNH2和P1-Ser(P2)-NMeTry(P3)-D-Asn-Leu-Lys(iPr,P4)-Pro-D-AlaNH2偶联。
